-
-There is no one today who has seen a living horse. The creature became
-extinct a couple of centuries ago, about the year 2,800. Man, who
-betrayed the horse into what he became, hardly regretted the passing.
-
-However, and I speak with all sincerity, there will be men of the
-future who will see a horse. Perhaps men of the future may ride
-horseback like knights and cowboys of the Middle Ages.
-
-The secret of time travel has been discovered. No one has traveled
-through time as yet, although man has explored the universe for more
-than twenty light years from the sun. But the day of time travel is not
-far distant. It had simple beginnings. All great things began in simple
-ways. Newton and the apple were the beginnings of modern understanding
-of the laws of the physical world; Watts and the teakettle were the
-origins of industry and the machine age. A very beautiful young woman
-and an unscrupulous man were responsible for time travel.
-
-I met the man early in the morning of July 2, 3002. I remember the
-date because on the day before I had visited in Alexandria, Egypt, and
-I had eaten dinner in Shanghai, China. It was nearly midnight when I
-reached the rocket port in Chicago and a jam in the pneumatics delayed
-my arrival home until nearly one o'clock in the morning.
-
-Blake, fully dressed, met me at the door. There was a worried look in
-his eyes.
-
-"There is a gentleman to see you, sir," Blake said. "I explained that
-you would not return until quite late and I tried to get him to leave,
-but he said it was urgent that he see you the minute you returned."
-Blake glanced over his shoulder toward the library and lowered his
-voice to a whisper. "I was a little frightened of him, sir. He doesn't
-seem quite--ah--quite right, sir, if you know what I mean. Shall I call
-the police?"
-
-"No, Blake." I felt confident of licking my weight in madmen and I
-entered the library.
-
-A tall, distinguished, dark haired gentleman rose to greet me.
-
-"Ah! Dr. Huckins! I was afraid you would not get here in time!"
-
-As he spoke I noticed a peculiar light in his eyes. It seemed to be a
-reflection from the fluorescent lamps of the library, but it showed a
-little too much of the whites of his eyes and I thought of what Blake
-had said about the man not being "quite right."
-
-I did not feel that I owed him an apology for keeping him waiting,
-since I usually received visitors by appointment.
-
-"I am Gustav Keeshwar!" he introduced himself. He seemed to expect some
-reaction, but unfortunately the name meant nothing to me, although if
-I had paid more attention to the newspapers I would have known who he
-was at once.
-
-"I am the president of the Stellar Transport Company," he announced.
-
-As he spoke he glanced secretively about the room, as though he feared
-an eavesdropper. Then he picked up a brief case which was lying on the
-table. With no explanation he opened it and pulled out package after
-package of thousand dollar bills.
-
-"You may count it if you wish," Keeshwar said. "There are 1,000 bills,
-each of one thousand dollar denomination. One million dollars in cold
-cash."
-
-There are any number of bank presidents who have never seen a million
-dollars in one pile. Spread out before me, I could scarcely grasp the
-amount of wealth it represented. As I recall now, my clearest mental
-reaction was a curiosity about how he managed to tuck it away so neatly
-in a brief case. Then I wondered if it was real money. A closer glance
-at the bills convinced me that it was.
-
-Suddenly I came to my senses. I closed the library door and locked it.
-I glanced nervously at the shades to make sure all were pulled down.
-
-"Great Scott, man, you shouldn't carry all that money around with you
-in a brief case!" As I said it, I spoke with the realization that the
-man was mad.
-
-"I brought the money to you," Keeshwar said. "It is yours if you will
-do one thing for me."
-
-"I must ask you to leave and to take your money with you," I said,
-realizing that I was turning down the ransom of a king. "No honest task
-ever called for a million dollars compensation--"
-
-"But you have not asked me what I wish you to do!" Keeshwar exploded.
-"Look! Do you see how much money a million dollars is?"
-
-I do not wish to pose as a man over-stocked with principles. A million
-dollars is more money than I ever hope to see again at one time.
-But I had a good income, a nice little fortune tucked away in worth
-while investments. I had a good name and my position in the world was
-better than average. I did not trust this man. I had a feeling that the
-million dollars he offered would not be worth the price.
-
-"I am a surgeon," I said. "If you wish my professional services, I will
-charge you a reasonable fee."
-
-"I want your services," Keeshwar said. "I want them for one day."
-
-"You may have them. I will send you a bill after I complete the task."
-
-"I want your services tomorrow," said Keeshwar, persistently.
-
-I shook my head. "I have a delicate operation scheduled tomorrow. It is
-an operation I cannot postpone."
-
-"It is an operation on Trella Mayo?"
-
-I started. "How did you know that?"
-
-"It is this operation that I wish you to perform for me," Keeshwar
-said. "Would it not be simple to let your knife slip, or to allow
-something to happen to her--for one million dollars!"
-
-I do not remember clearly what happened next. I think I knocked the man
-down. I do remember stuffing his million dollars into his brief case
-and throwing it after him out of the door.
-
-When I closed the door I was excited and unnerved. I found some
-sedative tablets and swallowed one. Then I sat down to think. Trella
-Mayo, beautiful, young and intelligent, a woman in a billion! Someone
-wanted to kill her.
-
-She was only twenty-eight, yet her discoveries in physics had astounded
-the world. She might have taken first place in any beauty contest, yet
-she preferred working in a laboratory with men too old to notice her
-charms.
-
-Her operation was not serious, except that it involved delicate skill.
-I resolved that nothing must happen during that operation the following
-day.
-
-Two weeks later I visited Trella, now convalescing from her operation.
-
-"I've wanted to talk to you, Fred," she said after I had taken her
-temperature, felt her pulse and gone through the usual ritual.
-
-"I must warn you that I'll send you a bill for any medical advice I
-give you," I replied, laughing.
-
-She smiled only a little and then puckered her brow seriously.
-
-"I wanted to ask you about that operation. Wasn't it performed under
-unusual circumstances?"
-
-I was taken by surprise and I am afraid that the truth forced its
-indications through my professional manner. "Why do you ask?"
-
-"I noticed Blake standing near the door. There seemed to be a bulge
-in his pocket. It couldn't have been a gun, could it? And you kept
-watching, as if you were afraid a tribe of Indians would drop in for a
-massacre. I wonder if there couldn't have been a tall, dark gentleman
-mixed up in these unusual precautions?"
-
-I did not reply.
-
-"And I've noticed during my convalescence that the internes that
-continually hover around my door have a look as if--well, shall I say
-that they look more like policemen than internes?"
-
-I laughed nervously. "I think you are a mental case, Miss Mayo," I
-said. "I shall have to call in a specialist."
-
-"You do not need to deny it, Fred," she said. "Why do you suppose I
-insisted that you perform the operation? Why didn't I let you call in
-someone else? It was because you are the only man in the world that I
-trust, Fred. How much did Gustav Keeshwar offer you to do me in?"
-
-Before I could stop myself I opened my mouth and blurted the truth.
-
-"One million dollars!"
-
-"Whew!" Trella whistled softly. "I'm worth a lot to you! I must be
-getting close if Keeshwar will pay a million to see me out of the way."
-
-"Trella," I pleaded. "What is it all about? What's behind this
-mystery?"
-
-"If you turned down a million dollars for my sake, I think I can trust
-you," she said. "Supposing I was about to invent a new method of
-locomotion? Can you see where Keeshwar might find me obnoxious?"
-
-"A new kind of space ship?"
-
-Trella shook her head. "A new kind of locomotion. Animals either swim
-or walk. Man also uses wheels."
-
-"He also can fly. So can birds."
-
-"Flying is simply swimming through the air and crawling, as a worm
-or snake, is gliding, like swimming. Space ships swim, too, after a
-fashion. Boats swim through the sea and sleds swim on ice. Therefore we
-have only three kinds of locomotion: Legs, wheels and sleds. Another
-might revolutionize everything."
-
-"But there couldn't be any other way to travel. Even the planets 'sled'
-through ether."
-
-"There is another way. It will open exploration to the furthest limits
-of the galaxy."
-
-"I can see why Keeshwar was so interested."
-
-"As soon as I'm out of bed, I want you to call on me at my laboratory,
-Fred. I'll show you something that will make your eyes pop out of your
-head."
-
-I turned to leave, when something on the window pane caught my eye.
-It was a small, cherry-red spot, about the size of a twenty-five cent
-piece.
-
-The minute I saw it, I knew what it was. I shouted to the
-interne--really a detective--outside the door, and lifted Trella into
-my arms. I must admit that I handled her a little roughly and she
-groaned as I hurried her out of the room. But what I did was necessary.
-
-As I left the room, the glass of the pane melted and a beam flashed
-across the room, striking the bed where Trella had been an instant
-before. That beam was an Oronic Ray, 5,000 degrees hot, of the type
-used in welding the rockets of space ships.
-
-It was evident that Gustav Keeshwar intended to finish Trella Mayo
-whether I would help him or not.
-
- * * * * *
-
-A few weeks later I visited Trella in her laboratory.
-
-"I'm anxious to see this incomprehensible conveyance," I explained.
-
-"At least, I'm glad you are taking an interest in something besides my
-safety and my operation scar," she replied.
-
-She led me through a corridor toward a heavy steel door, which she
-unlocked.
-
-"You are the first person besides myself to go into this room in the
-past five years," Trella added.
-
-I scarcely know what I had expected to see. What would anyone expect
-to see, if he was told he was going to be shown a machine that
-neither walked, glided nor rolled? Such a contraption is beyond human
-experience.
-
-It was a long, hollow tube, large enough to hold a human body. It was
-made of quartz and on each side was a cylindrical, low power atomic
-energy machine.
-
-"This," Trella said, "is the translator."
-
-"The what?"
-
-"I call it my space-time translator, which someday will make the rocket
-as obsolete for space travel as the horse for surface travel. It will
-take an object from one point in space-time to another instantly."
-
-"Instantly?"
-
-"There is a small lapse of time," Trella confessed. "You see the
-machine has two motors, one for starting the operation and the other
-for completing it. It takes about one second's time to switch the
-motive power from one motor to the other."
-
-The machine, except for the motors, was made entirely of quartz and
-silver. On the right side of the machine was a long strip of silver
-running the full length of the tube. It was about three inches wide and
-it was connected with a knife-like blade of silver on the left side
-of the tube by a strand of silver wire. Silver was used, of course,
-because it was the best known conductor of electricity and other forms
-of energy.
-
-"It would be wonderful if it worked," I said.
-
-"It does work," Trella said. "We sent two guinea pigs to the Sirius
-system yesterday morning. We got them back in an hour with a copy of
-yesterday's issue of _The Sirian Daily Universe_. Here's the paper."
-
-She held out a copy of the beautifully printed daily magazine. On the
-cover was the date, August V2, 504 (3002).
-
-It was customary for terrestrials to use terrestrial dates wherever
-their outposts were located in the stellar system. But instead of using
-the terrestrial year--as shown in parenthesis on _The Sirian Daily
-Universe_--the year always was reckoned from the date when the planet
-was first visited by an expedition from the solar system. Although days
-were not always the same, twenty-four hour periods could be reckoned
-quite easily so that on some planets a single day might have more than
-one terrestrial date, and on others a single day would be a fraction of
-a legal day. The number of actual days usually was indicated by a Roman
-numeral preceding the Arabic figure. Thus August V2 indicated that
-Sirius had risen and set five times while the sun had done so twice
-during the month of August.
-
-"Unbelievable!" I said. "How does it work?"
-
-"It operates through time," Trella explained. "It takes a short cut
-between two parallel instants."
-
-She took a guinea pig from a cage in the laboratory. She put the
-wriggling animal inside the quartz tube and strapped it firmly in the
-center.
-
-"Watch," she said.
-
-She turned a switch on one of the boxes. A low hum arose from the
-atomic motor. Trella watched a dial located in the top of the quartz
-tube until an arrow pointed to a gold star. Then she pressed a button
-in the motor on the right side of the machine.
-
-I noticed that the translator had controls that could be operated from
-inside the tube as well as from the outside.
-
-There were two distinct gasps of the motor. Half of the guinea pig
-disappeared with the first gasp and the remaining half disappeared with
-the second.
-
-Where the tube had been a second before, there was nothing now.
-
-"He's on Proxima Centaur now," Trella said. "I managed to equip a
-laboratory there about two years ago. It was through that laboratory
-that Keeshwar learned of my experiments in translation. My men on
-Proxima will send back the guinea pig in a few minutes."
-
-We sat down and waited. Trella explained the machine, although at the
-time the explanation was a little over my head. The actual translation
-was accomplished by the pushing of one motor and the pulling of another
-across an extra-dimensional space. Half of the object to be translated
-was hurled across space by the pushing of the first motor. The second
-motor, which operated automatically, began pulling the other half,
-including the first motor, after it as soon as it materialized at the
-end of the journey.
-
-By means of radio signals the exact location of every explored planet
-had been determined. It was therefore only a matter of mathematical
-calculation to find the target. There was some risk, of course, if a
-mathematical error were made in computing the range but considering the
-risks involved in ordinary methods of interstellar flight everything
-was in favor of the translator.
-
-"The whole secret of the invention lies in locating the proper _Now_ in
-space-time," Trella explained.
-
-"The proper _Now_?" I asked.
-
-"Of course," she said, "the _Now_ we experience on earth is not the
-same _Now_ that exists simultaneously on Rihlon, the second planet
-of Proxima Centaur. We are dealing with space-time, Fred. Time is a
-dimension, it stretches like a line through space. If we connect the
-_Now_ of the present with the _Now_ of ten minutes ago, we have a
-straight line, just as we would have a straight line if we connected
-any two points in the universe. The _Now_ of the present and the _Now_
-ten minutes ago on Rihlon also would be a straight line, but it would
-not be the same straight line."
-
-"But it would be parallel!" I exclaimed, beginning to see her point.
-
-"Oh, so you _do_ know something about mathematics?"
-
-"Of course! If you connect the _Nows_ of the present on both the earth
-and Rihlon, you have a straight line, perpendicular to the parallel
-time lines of both the earth and Rihlon. Why couldn't your invention be
-used for time travel? Couldn't you connect the present--_Now_ of Rihlon
-with any _Now_ in the time line of the earth--any _Now_ of the past or
-future?"
-
-"The idea occurred to me, but it won't work," Trella replied. "There's
-a serious obstacle we can't overcome. In going backward or forward in
-time we do not travel in lines perpendicular to the parallel time lines
-of the earth and Rihlon--or for any other planet for that matter. But
-we travel like this--" Trella drew a figure on a piece of paper.

-
-"The line AB represents the time line of the earth and the line CD
-represents the time line of any other planet X. The two lines are
-parallel. E represents the earth--_Now_, and F the _Now_ on planet X. A
-line connecting the two is perpendicular to both AB and CD. Supposing
-we should travel from F to a point G, a _Now_ in the earth's past. If
-we connect F and G we would have a right triangle GEF. The hypothenuse
-GF would be the square root of GE squared plus EF squared."
-
-"There is nothing mathematically implausible in that," I said.
-
-"There is nothing implausible, yet to determine the exact distance from
-G to F is in most cases impossible. Unless the distances involved are
-of the proper ratio, say, 4 and 5, the line GF becomes an irrational
-number, of which it is impossible to find the exact value. Supposing
-the distance from E to F was one light-year and the distance from G
-to E, one year. Then GF would be the square root of one squared plus
-one squared, or the square root of two. Because we are dealing with
-such immense distances and because even the smallest decimal point of
-error might lead to disastrous results, we cannot attempt time travel
-unless we know the exact value of the square root of two, or any other
-irrational number."
-
-As Trella finished speaking there was a coughing hum and the translator
-appeared in the room, containing the unharmed guinea pig and a copy of
-the _Rihlon Gazette_ for Aug. 3rd, which was this day.
-
-"Do you believe me?" she cried gleefully, waving the paper over her
-head.
-
-It was quite convincing, I admitted.
-
-"Now I am going to make a trip in the translator!"
-
-"You!"
-
-It was the beginning of a long argument. There was danger in the trip,
-I told her, and Trella had come to mean a great deal to me. She scoffed
-at my fears and told me that if I didn't care to witness the first
-translation of man to another planet in another star system she would
-do it when I wasn't there.
-
-Of course, no man can win an argument with a woman.
-
-Trella climbed into the translator.
-
-I closed the opening. Her hand rose to the switch that operated the
-mechanism from inside the tube. She smiled and her lips moved in a
-cheerful good-by. Then she touched the switch.
-
-The indicator on the dial crept upward toward the gold star.
-
-Suddenly the unexpected occurred.
-
-The door of the laboratory opened. Trella had forgotten to lock the
-door when we entered the room.
-
-As I heard the noise, I turned and saw Gustav Keeshwar leveling a gun
-toward the helpless young woman in the glass tube.
-
-I sprang toward him just as the gun went off.
-
-Apparently he had not expected to find me in the room, for as I lunged
-he uttered a cry and threw the gun at my face. Then he turned and ran.
-
-I managed to duck in time to receive only a glancing blow on the head.
-I started to pursue, when my eyes fell on the translator.
-
-Something terrible was wrong.
-
-Half of the tube had disappeared and, with it, half of Trella's body.
-The other half, containing half of the most beautiful woman on the
-earth, remained in the laboratory.
-
-My spring toward Keeshwar had spoiled his aim enough to keep the bullet
-from striking Trella, but the bullet had struck the small silver wire
-that ran from the atomic motor on one side to the atomic motor on the
-other. The translation had been only half completed.
-
-Half of Trella's body was on the earth, while the other was on Rihlon,
-four light years away!
-
-Her single eye was open and her half-face was frozen in an expression
-of terror. She did not move and she was not breathing. There was no
-blood. It was a complete suspension of animation.
-
-Suddenly I realized that I was losing precious seconds. Unless
-something was done, Trella would die.
-
-I picked up the bit of wire that had been broken off by Keeshwar's
-bullet. I lifted it toward the end dangling from the motor.
-
-Then Trella moved! It was not suspended animation, but something
-else--something new!
-
-Her eye swung toward me. Her half-head visibly shook. Her half-lips
-moved but no sound of her voice reached me. But I understood. She was
-telling me not to replace the wire.
-
-She lifted her hand and drew a right-angled triangle on the side of the
-tube.
-
-I understood. Trella was alive and she would continue to live, but it
-would be impossible to restore her component halves merely by mending
-the broken wire.
-
-Trella was linked in time. She was still whole, but half of her body
-was visible in one _Now_ and the other half in a _Now_ on Proxima
-Centaur, four light years away.
-
-To join the halves of her body, would mean joining the two _Nows_ and
-to do that would form a triangle, at least one side of which would be
-an irrational number. Unless the riddle of time travel were solved, it
-would be impossible to make Trella whole.
-
-I walked around the half-tube. Her appearance was not what I expected
-to see. It was not a case of sawing a woman in half. The cross section
-of her body appeared only as an opaque blankness. When I touched
-her side I felt something cold and hard. It was as if I had touched
-eternity.
-
-The laboratory officials were called in for consultation. It was
-decided that the matter should be hushed, at least until we knew what
-should be done. There was too much to do now to be bothered with police
-and reporters. We would not have a warrant issued for Keeshwar. There
-would be time to deal with him later.
-
-We discovered that Trella could eat and she seemed to be in perfect
-health. But I knew that she was doomed unless we could restore the
-parts of her body. Her muscles would atrophy. Inaction is more deadly
-to the human machine than millions of disease germs.
-
-If it would be possible to locate some day in the future when the wires
-might be pieced together and the linking of Trella's two halves might
-be accomplished without rationalizing irrational numbers, our problem
-would be solved. But the nearest date in the future when this could be
-done was three years ahead.[1]
-
-[Footnote 1: Three years from the time this accident occurred would
-make the sides of the triangle between the past event, the present, and
-the present on Rihlon (four light years away) equal to the units 3, 4
-and 5. Three squared, plus four squared equals five squared.]
-
-But in three years Trella would be dead. We could not wait for the
-coordinates to adjust themselves. We had to make the coordinates
-adjustable to our purposes.
-
-A small chronometer located in the atomic energy machine on the quartz
-tube gave us the exact time the silver wire had been broken.
-
-Even Blake, my servant, offered a suggestion:
-
-"If you could take the earth half of Miss Trella's body to Rihlon, or
-bring the Rihlon half to earth and bring the two _Nows_ together, would
-that form a rational triangle?"
-
-I took paper and pencil and tried to figure it out.

-The line BA represented the time line of Rihlon. The line CD was the
-time line of the earth. The points E and F were the _Nows_ on Rihlon
-and earth, respectively, at which the accident occurred. The point G
-represented the _Now_ at which a space ship would leave the earth for
-Rihlon carrying Trella's half body. The point H represented the _Now_
-of arrival on Rihlon and the point J the parallel point on earth.
-We still had a right-angled triangle and we still had to deal with
-irrational numbers. But hold on--
-
-I gazed at my drawing. Before my eyes was the answer! The whole thing
-was clearly and completely solved. The secret of time travel was
-solved. Trella was saved. The invention of the translator had been
-perfected so that all danger of becoming lost in time was removed![2]
-
-[Footnote 2: As a mental exercise, I would suggest that the reader look
-at Figure 2 for a minute or two and figure out the answer. The answer
-is there and high school mathematics should enable a person to discover
-how to extract the irrational number.--Dr. Fred Huckins.]
-
-"Blake," I said to the servant, "bring me my automatic pistol."
-
-"Wh-what?" Blake stuttered.
-
-"I said bring me my automatic pistol. I'm going to save Trella, or
-murder somebody."
-
-"Perhaps I should call your lawyer."
-
-I threw a book at him and he left hurriedly, to return in a few minutes
-with my pistol and holster. I strapped the weapon about my waist and
-slammed my straw hat on my head. In a few minutes I stepped from a taxi
-in front of the Galaxy building, in which the officers of the Stellar
-Transport Company are located.
-
-A clerk with thick glasses interviewed me.
-
-"I want to charter a ship for a trip to Proxima Centaur," I explained.
-"I want one of your late model cruisers which can go about ten times
-the speed of light. I want to get there quickly."
-
-The clerk nodded. I have often wondered about the composure of clerks
-who never seem to be astonished at anything. "We have a ship available
-that could get you there in three months, that's sixteen times the
-speed of light. But to charter it would cost one million dollars."
-
-He never batted an eye when he named the price. I doubt if the clerk
-was receiving more than forty a week.
-
-"I should like to transact the deal directly with Mr. Keeshwar," I said.
-
-"He will be pleased, I'm sure," the clerk replied. "What is your name?"
-
-"Andrew J. Colt," I said, for lack of more originality.
-
-The clerk disappeared into the sanctum. He returned presently with:
-
-"Mr. Keeshwar will see you, Mr. Colt."
-
-I had counted on Keeshwar being--or pretending to be very busy as I
-entered. I expected him to pay no attention to my entry, and not even
-to glance in my direction, as if a million dollars were a trifling
-matter, until we were alone.
-
-I judged Keeshwar right. When at last he glanced at me he was unnerved
-by the presence of an automatic pistol which was pointed directly at
-his head.
-
-"I must warn you not to touch any of those buttons on your desk," I
-said. "It would give me a great deal of pleasure to drill you and I
-won't go out of my way for an opportunity."
-
-"Wh-what d-d-do you w-w-ant?" he asked, turning pale.
-
-"One day you offered me a million dollars to take Miss Mayo's life,"
-I said. "Now I'm asking you to contribute an equal amount to save it.
-However, I'm willing to take it out in trade. I want you to pilot one
-of your ships for me to Rihlon."
-
-"Impossible!" Keeshwar said, regaining some of his composure. "I
-couldn't leave my business for a period long enough to make the trip."
-
-"If you don't leave your business to make the trip right now you won't
-exist any more," I warned casually. I reached into my pocket and
-brought out a silencer, which I fitted to the end of the pistol barrel.
-I unfastened the safety and aimed deliberately.
-
- * * * * *
-
-The space ship containing the terrestrial half of Trella Mayo, in
-company with myself, Blake, two other scientists and Gustav Keeshwar,
-arrived on Rihlon three months later. Keeshwar, who had had a pistol
-trained on him almost every instant since I had called at his office,
-was released and permitted to return to earth. He did not know that I
-had left the instructions on earth for his arrest for felonious assault
-the minute he landed.
-
-We located Trella's Rihlon laboratory. It was the matter of a few
-minutes to make the connection of the broken wire and to finish the
-translation of her two halves.
-
-Trella stepped out of her quartz prison, swayed unsteadily for a second
-on her feet, and then collapsed.
-
-"How on earth did you do it?" she asked. "How did you reconcile the
-irrational number?"
-
-I sketched the figure roughly (Figure 2). "The distance from F to G and
-the distance from E to H does not enter into the equation," I said.
-"The only thing we are interested in is the distances GJ, JH and GH."
-
-"And GH is an irrational number," Trella said.
-
-"Quite right, although like most things that appear absurd on the
-surface, it is not as irrational as it seems. The distance G to J
-is three months, the time required for the flight from the earth to
-Rihlon. We will represent this by the unit 1. The distance JH is
-four light years, the distance in space from earth to Rihlon. This,
-therefore, would be sixteen units. Using the formula (GJ)^2 plus (JH)^2
-equals (GH)^2 we find that GH is the square root of one plus 256, or
-257. The square root of 257 is 16.031228, etc., an irrational number.
-
-"It can't be expressed in figures! We do not need figures when we can
-draw a picture. The triangle GHJ is a picture of an irrational number.
-We had only to go to Rihlon to complete the equation."
-
-"Time can be traveled," Trella said.
-
-"Where would you like to go on our honeymoon?" I asked.
-
-"To the Garden of Eden," she said.

-1.F.
-
-1.F.1. Project Gutenberg volunteers and employees expend considerable
-effort to identify, do copyright research on, transcribe and proofread
-works not protected by U.S. copyright law in creating the Project
-Gutenberg-tm collection. Despite these efforts, Project Gutenberg-tm
-electronic works, and the medium on which they may be stored, may
-contain "Defects," such as, but not limited to, incomplete, inaccurate
-or corrupt data, transcription errors, a copyright or other
-intellectual property infringement, a defective or damaged disk or

-Defect you cause.
-
-Section 2. Information about the Mission of Project Gutenberg-tm
-
-Project Gutenberg-tm is synonymous with the free distribution of
-electronic works in formats readable by the widest variety of
-computers including obsolete, old, middle-aged and new computers. It
-exists because of the efforts of hundreds of volunteers and donations
-from people in all walks of life.
-
-Volunteers and financial support to provide volunteers with the
-assistance they need are critical to reaching Project Gutenberg-tm's
-goals and ensuring that the Project Gutenberg-tm collection will
-remain freely available for generations to come. In 2001, the Project
-Gutenberg Literary Archive Foundation was created to provide a secure
-and permanent future for Project Gutenberg-tm and future
-generations. To learn more about the Project Gutenberg Literary
-Archive Foundation and how your efforts and donations can help, see
-Sections 3 and 4 and the Foundation information page at
-www.gutenberg.org
-
-Section 3. Information about the Project Gutenberg Literary
-Archive Foundation
-
-The Project Gutenberg Literary Archive Foundation is a non-profit
-501(c)(3) educational corporation organized under the laws of the
-state of Mississippi and granted tax exempt status by the Internal
-Revenue Service. The Foundation's EIN or federal tax identification
-number is 64-6221541. Contributions to the Project Gutenberg Literary
-Archive Foundation are tax deductible to the full extent permitted by
-U.S. federal laws and your state's laws.
-
-The Foundation's business office is located at 809 North 1500 West,
-Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up
-to date contact information can be found at the Foundation's website
-and official page at www.gutenberg.org/contact
-
-Section 4. Information about Donations to the Project Gutenberg
-Literary Archive Foundation
-
-Project Gutenberg-tm depends upon and cannot survive without
-widespread public support and donations to carry out its mission of
-increasing the number of public domain and licensed works that can be
-freely distributed in machine-readable form accessible by the widest
-array of equipment including outdated equipment. Many small donations
-($1 to $5,000) are particularly important to maintaining tax exempt
-status with the IRS.
-
-The Foundation is committed to complying with the laws regulating
-charities and charitable donations in all 50 states of the United
-States. Compliance requirements are not uniform and it takes a
-considerable effort, much paperwork and many fees to meet and keep up
-with these requirements. We do not solicit donations in locations
-where we have not received written confirmation of compliance. To SEND
-DONATIONS or determine the status of compliance for any particular
-state visit www.gutenberg.org/donate
-
-While we cannot and do not solicit contributions from states where we
-have not met the solicitation requirements, we know of no prohibition
-against accepting unsolicited donations from donors in such states who
-approach us with offers to donate.
-
-International donations are gratefully accepted, but we cannot make
-any statements concerning tax treatment of donations received from
-outside the United States. U.S. laws alone swamp our small staff.
-
-Please check the Project Gutenberg web pages for current donation
-methods and addresses. Donations are accepted in a number of other
-ways including checks, online payments and credit card donations. To
-donate, please visit: www.gutenberg.org/donate
-
-Section 5. General Information About Project Gutenberg-tm electronic works
-
-Professor Michael S. Hart was the originator of the Project
-Gutenberg-tm concept of a library of electronic works that could be
-freely shared with anyone. For forty years, he produced and
-distributed Project Gutenberg-tm eBooks with only a loose network of
-volunteer support.
-
-Project Gutenberg-tm eBooks are often created from several printed
-editions, all of which are confirmed as not protected by copyright in
-the U.S. unless a copyright notice is included. Thus, we do not
-necessarily keep eBooks in compliance with any particular paper
-edition.
-
-Most people start at our website which has the main PG search
-facility: www.gutenberg.org
-
-This website includes information about Project Gutenberg-tm,
-including how to make donations to the Project Gutenberg Literary
-Archive Foundation, how to help produce our new eBooks, and how to
-subscribe to our email newsletter to hear about new eBooks.

-<p>There is no one today who has seen a living horse. The creature became
-extinct a couple of centuries ago, about the year 2,800. Man, who
-betrayed the horse into what he became, hardly regretted the passing.</p>
-
-<p>However, and I speak with all sincerity, there will be men of the
-future who will see a horse. Perhaps men of the future may ride
-horseback like knights and cowboys of the Middle Ages.</p>
-
-<p>The secret of time travel has been discovered. No one has traveled
-through time as yet, although man has explored the universe for more
-than twenty light years from the sun. But the day of time travel is not
-far distant. It had simple beginnings. All great things began in simple
-ways. Newton and the apple were the beginnings of modern understanding
-of the laws of the physical world; Watts and the teakettle were the
-origins of industry and the machine age. A very beautiful young woman
-and an unscrupulous man were responsible for time travel.</p>
-
-<p>I met the man early in the morning of July 2, 3002. I remember the
-date because on the day before I had visited in Alexandria, Egypt, and
-I had eaten dinner in Shanghai, China. It was nearly midnight when I
-reached the rocket port in Chicago and a jam in the pneumatics delayed
-my arrival home until nearly one o'clock in the morning.</p>
-
-<p>Blake, fully dressed, met me at the door. There was a worried look in
-his eyes.</p>
-
-<p>"There is a gentleman to see you, sir," Blake said. "I explained that
-you would not return until quite late and I tried to get him to leave,
-but he said it was urgent that he see you the minute you returned."
-Blake glanced over his shoulder toward the library and lowered his
-voice to a whisper. "I was a little frightened of him, sir. He doesn't
-seem quite&mdash;ah&mdash;quite right, sir, if you know what I mean. Shall I call
-the police?"</p>
-
-<p>"No, Blake." I felt confident of licking my weight in madmen and I
-entered the library.</p>
-
-<p>A tall, distinguished, dark haired gentleman rose to greet me.</p>
-
-<p>"Ah! Dr. Huckins! I was afraid you would not get here in time!"</p>
-
-<p>As he spoke I noticed a peculiar light in his eyes. It seemed to be a
-reflection from the fluorescent lamps of the library, but it showed a
-little too much of the whites of his eyes and I thought of what Blake
-had said about the man not being "quite right."</p>
-
-<p>I did not feel that I owed him an apology for keeping him waiting,
-since I usually received visitors by appointment.</p>
-
-<p>"I am Gustav Keeshwar!" he introduced himself. He seemed to expect some
-reaction, but unfortunately the name meant nothing to me, although if
-I had paid more attention to the newspapers I would have known who he
-was at once.</p>
-
-<p>"I am the president of the Stellar Transport Company," he announced.</p>
-
-<p>As he spoke he glanced secretively about the room, as though he feared
-an eavesdropper. Then he picked up a brief case which was lying on the
-table. With no explanation he opened it and pulled out package after
-package of thousand dollar bills.</p>
-
-<p>"You may count it if you wish," Keeshwar said. "There are 1,000 bills,
-each of one thousand dollar denomination. One million dollars in cold
-cash."</p>
-
-<p>There are any number of bank presidents who have never seen a million
-dollars in one pile. Spread out before me, I could scarcely grasp the
-amount of wealth it represented. As I recall now, my clearest mental
-reaction was a curiosity about how he managed to tuck it away so neatly
-in a brief case. Then I wondered if it was real money. A closer glance
-at the bills convinced me that it was.</p>
-
-<p>Suddenly I came to my senses. I closed the library door and locked it.
-I glanced nervously at the shades to make sure all were pulled down.</p>
-
-<p>"Great Scott, man, you shouldn't carry all that money around with you
-in a brief case!" As I said it, I spoke with the realization that the
-man was mad.</p>
-
-<p>"I brought the money to you," Keeshwar said. "It is yours if you will
-do one thing for me."</p>
-
-<p>"I must ask you to leave and to take your money with you," I said,
-realizing that I was turning down the ransom of a king. "No honest task
-ever called for a million dollars compensation&mdash;"</p>
-
-<p>"But you have not asked me what I wish you to do!" Keeshwar exploded.
-"Look! Do you see how much money a million dollars is?"</p>
-
-<p>I do not wish to pose as a man over-stocked with principles. A million
-dollars is more money than I ever hope to see again at one time.
-But I had a good income, a nice little fortune tucked away in worth
-while investments. I had a good name and my position in the world was
-better than average. I did not trust this man. I had a feeling that the
-million dollars he offered would not be worth the price.</p>
-
-<p>"I am a surgeon," I said. "If you wish my professional services, I will
-charge you a reasonable fee."</p>
-
-<p>"I want your services," Keeshwar said. "I want them for one day."</p>
-
-<p>"You may have them. I will send you a bill after I complete the task."</p>
-
-<p>"I want your services tomorrow," said Keeshwar, persistently.</p>
-
-<p>I shook my head. "I have a delicate operation scheduled tomorrow. It is
-an operation I cannot postpone."</p>
-
-<p>"It is an operation on Trella Mayo?"</p>
-
-<p>I started. "How did you know that?"</p>
-
-<p>"It is this operation that I wish you to perform for me," Keeshwar
-said. "Would it not be simple to let your knife slip, or to allow
-something to happen to her&mdash;for one million dollars!"</p>
-
-<p>I do not remember clearly what happened next. I think I knocked the man
-down. I do remember stuffing his million dollars into his brief case
-and throwing it after him out of the door.</p>
-
-<p>When I closed the door I was excited and unnerved. I found some
-sedative tablets and swallowed one. Then I sat down to think. Trella
-Mayo, beautiful, young and intelligent, a woman in a billion! Someone
-wanted to kill her.</p>
-
-<p>She was only twenty-eight, yet her discoveries in physics had astounded
-the world. She might have taken first place in any beauty contest, yet
-she preferred working in a laboratory with men too old to notice her
-charms.</p>
-
-<p>Her operation was not serious, except that it involved delicate skill.
-I resolved that nothing must happen during that operation the following
-day.</p>
-
-<p>Two weeks later I visited Trella, now convalescing from her operation.</p>
-
-<p>"I've wanted to talk to you, Fred," she said after I had taken her
-temperature, felt her pulse and gone through the usual ritual.</p>
-
-<p>"I must warn you that I'll send you a bill for any medical advice I
-give you," I replied, laughing.</p>
-
-<p>She smiled only a little and then puckered her brow seriously.</p>
-
-<p>"I wanted to ask you about that operation. Wasn't it performed under
-unusual circumstances?"</p>
-
-<p>I was taken by surprise and I am afraid that the truth forced its
-indications through my professional manner. "Why do you ask?"</p>
-
-<p>"I noticed Blake standing near the door. There seemed to be a bulge
-in his pocket. It couldn't have been a gun, could it? And you kept
-watching, as if you were afraid a tribe of Indians would drop in for a
-massacre. I wonder if there couldn't have been a tall, dark gentleman
-mixed up in these unusual precautions?"</p>
-
-<p>I did not reply.</p>
-
-<p>"And I've noticed during my convalescence that the internes that
-continually hover around my door have a look as if&mdash;well, shall I say
-that they look more like policemen than internes?"</p>
-
-<p>I laughed nervously. "I think you are a mental case, Miss Mayo," I
-said. "I shall have to call in a specialist."</p>
-
-<p>"You do not need to deny it, Fred," she said. "Why do you suppose I
-insisted that you perform the operation? Why didn't I let you call in
-someone else? It was because you are the only man in the world that I
-trust, Fred. How much did Gustav Keeshwar offer you to do me in?"</p>
-
-<p>Before I could stop myself I opened my mouth and blurted the truth.</p>
-
-<p>"One million dollars!"</p>
-
-<p>"Whew!" Trella whistled softly. "I'm worth a lot to you! I must be
-getting close if Keeshwar will pay a million to see me out of the way."</p>
-
-<p>"Trella," I pleaded. "What is it all about? What's behind this
-mystery?"</p>
-
-<p>"If you turned down a million dollars for my sake, I think I can trust
-you," she said. "Supposing I was about to invent a new method of
-locomotion? Can you see where Keeshwar might find me obnoxious?"</p>
-
-<p>"A new kind of space ship?"</p>
-
-<p>Trella shook her head. "A new kind of locomotion. Animals either swim
-or walk. Man also uses wheels."</p>
-
-<p>"He also can fly. So can birds."</p>
-
-<p>"Flying is simply swimming through the air and crawling, as a worm
-or snake, is gliding, like swimming. Space ships swim, too, after a
-fashion. Boats swim through the sea and sleds swim on ice. Therefore we
-have only three kinds of locomotion: Legs, wheels and sleds. Another
-might revolutionize everything."</p>
-
-<p>"But there couldn't be any other way to travel. Even the planets 'sled'
-through ether."</p>
-
-<p>"There is another way. It will open exploration to the furthest limits
-of the galaxy."</p>
-
-<p>"I can see why Keeshwar was so interested."</p>
-
-<p>"As soon as I'm out of bed, I want you to call on me at my laboratory,
-Fred. I'll show you something that will make your eyes pop out of your
-head."</p>
-
-<p>I turned to leave, when something on the window pane caught my eye.
-It was a small, cherry-red spot, about the size of a twenty-five cent
-piece.</p>
-
-<p>The minute I saw it, I knew what it was. I shouted to the
-interne&mdash;really a detective&mdash;outside the door, and lifted Trella into
-my arms. I must admit that I handled her a little roughly and she
-groaned as I hurried her out of the room. But what I did was necessary.</p>
-
-<p>As I left the room, the glass of the pane melted and a beam flashed
-across the room, striking the bed where Trella had been an instant
-before. That beam was an Oronic Ray, 5,000 degrees hot, of the type
-used in welding the rockets of space ships.</p>
-
-<p>It was evident that Gustav Keeshwar intended to finish Trella Mayo
-whether I would help him or not.</p>
-
-<hr class="tb" />
-
-<p>A few weeks later I visited Trella in her laboratory.</p>
-
-<p>"I'm anxious to see this incomprehensible conveyance," I explained.</p>
-
-<p>"At least, I'm glad you are taking an interest in something besides my
-safety and my operation scar," she replied.</p>
-
-<p>She led me through a corridor toward a heavy steel door, which she
-unlocked.</p>
-
-<p>"You are the first person besides myself to go into this room in the
-past five years," Trella added.</p>
-
-<p>I scarcely know what I had expected to see. What would anyone expect
-to see, if he was told he was going to be shown a machine that
-neither walked, glided nor rolled? Such a contraption is beyond human
-experience.</p>
-
-<p>It was a long, hollow tube, large enough to hold a human body. It was
-made of quartz and on each side was a cylindrical, low power atomic
-energy machine.</p>
-
-<p>"This," Trella said, "is the translator."</p>
-
-<p>"The what?"</p>
-
-<p>"I call it my space-time translator, which someday will make the rocket
-as obsolete for space travel as the horse for surface travel. It will
-take an object from one point in space-time to another instantly."</p>
-
-<p>"Instantly?"</p>
-
-<p>"There is a small lapse of time," Trella confessed. "You see the
-machine has two motors, one for starting the operation and the other
-for completing it. It takes about one second's time to switch the
-motive power from one motor to the other."</p>
-
-<p>The machine, except for the motors, was made entirely of quartz and
-silver. On the right side of the machine was a long strip of silver
-running the full length of the tube. It was about three inches wide and
-it was connected with a knife-like blade of silver on the left side
-of the tube by a strand of silver wire. Silver was used, of course,
-because it was the best known conductor of electricity and other forms
-of energy.</p>
-
-<p>"It would be wonderful if it worked," I said.</p>
-
-<p>"It does work," Trella said. "We sent two guinea pigs to the Sirius
-system yesterday morning. We got them back in an hour with a copy of
-yesterday's issue of <i>The Sirian Daily Universe</i>. Here's the paper."</p>
-
-<p>She held out a copy of the beautifully printed daily magazine. On the
-cover was the date, August V2, 504 (3002).</p>
-
-<p>It was customary for terrestrials to use terrestrial dates wherever
-their outposts were located in the stellar system. But instead of using
-the terrestrial year&mdash;as shown in parenthesis on <i>The Sirian Daily
-Universe</i>&mdash;the year always was reckoned from the date when the planet
-was first visited by an expedition from the solar system. Although days
-were not always the same, twenty-four hour periods could be reckoned
-quite easily so that on some planets a single day might have more than
-one terrestrial date, and on others a single day would be a fraction of
-a legal day. The number of actual days usually was indicated by a Roman
-numeral preceding the Arabic figure. Thus August V2 indicated that
-Sirius had risen and set five times while the sun had done so twice
-during the month of August.</p>
-
-<p>"Unbelievable!" I said. "How does it work?"</p>
-
-<p>"It operates through time," Trella explained. "It takes a short cut
-between two parallel instants."</p>
-
-<p>She took a guinea pig from a cage in the laboratory. She put the
-wriggling animal inside the quartz tube and strapped it firmly in the
-center.</p>
-
-<p>"Watch," she said.</p>
-
-<p>She turned a switch on one of the boxes. A low hum arose from the
-atomic motor. Trella watched a dial located in the top of the quartz
-tube until an arrow pointed to a gold star. Then she pressed a button
-in the motor on the right side of the machine.</p>
-
-<p>I noticed that the translator had controls that could be operated from
-inside the tube as well as from the outside.</p>
-
-<p>There were two distinct gasps of the motor. Half of the guinea pig
-disappeared with the first gasp and the remaining half disappeared with
-the second.</p>
-
-<p>Where the tube had been a second before, there was nothing now.</p>
-
-<p>"He's on Proxima Centaur now," Trella said. "I managed to equip a
-laboratory there about two years ago. It was through that laboratory
-that Keeshwar learned of my experiments in translation. My men on
-Proxima will send back the guinea pig in a few minutes."</p>
-
-<p>We sat down and waited. Trella explained the machine, although at the
-time the explanation was a little over my head. The actual translation
-was accomplished by the pushing of one motor and the pulling of another
-across an extra-dimensional space. Half of the object to be translated
-was hurled across space by the pushing of the first motor. The second
-motor, which operated automatically, began pulling the other half,
-including the first motor, after it as soon as it materialized at the
-end of the journey.</p>
-
-<p>By means of radio signals the exact location of every explored planet
-had been determined. It was therefore only a matter of mathematical
-calculation to find the target. There was some risk, of course, if a
-mathematical error were made in computing the range but considering the
-risks involved in ordinary methods of interstellar flight everything
-was in favor of the translator.</p>
-
-<p>"The whole secret of the invention lies in locating the proper <i>Now</i> in
-space-time," Trella explained.</p>
-
-<p>"The proper <i>Now</i>?" I asked.</p>
-
-<p>"Of course," she said, "the <i>Now</i> we experience on earth is not the
-same <i>Now</i> that exists simultaneously on Rihlon, the second planet
-of Proxima Centaur. We are dealing with space-time, Fred. Time is a
-dimension, it stretches like a line through space. If we connect the
-<i>Now</i> of the present with the <i>Now</i> of ten minutes ago, we have a
-straight line, just as we would have a straight line if we connected
-any two points in the universe. The <i>Now</i> of the present and the <i>Now</i>
-ten minutes ago on Rihlon also would be a straight line, but it would
-not be the same straight line."</p>
-
-<p>"But it would be parallel!" I exclaimed, beginning to see her point.</p>
-
-<p>"Oh, so you <i>do</i> know something about mathematics?"</p>
-
-<p>"Of course! If you connect the <i>Nows</i> of the present on both the earth
-and Rihlon, you have a straight line, perpendicular to the parallel
-time lines of both the earth and Rihlon. Why couldn't your invention be
-used for time travel? Couldn't you connect the present&mdash;<i>Now</i> of Rihlon
-with any <i>Now</i> in the time line of the earth&mdash;any <i>Now</i> of the past or
-future?"</p>
-
-<p>"The idea occurred to me, but it won't work," Trella replied. "There's
-a serious obstacle we can't overcome. In going backward or forward in
-time we do not travel in lines perpendicular to the parallel time lines
-of the earth and Rihlon&mdash;or for any other planet for that matter. But
-we travel like this&mdash;" Trella drew a figure on a piece of paper.</p>
-
-<hr class="chap" />
-
-<div class="figcenter">
- <img src="images/fig1.jpg" alt=""/>
-</div>
-
-<hr class="chap" />
-
-<p>"The line AB represents the time line of the earth and the line CD
-represents the time line of any other planet X. The two lines are
-parallel. E represents the earth&mdash;<i>Now</i>, and F the <i>Now</i> on planet X. A
-line connecting the two is perpendicular to both AB and CD. Supposing
-we should travel from F to a point G, a <i>Now</i> in the earth's past. If
-we connect F and G we would have a right triangle GEF. The hypothenuse
-GF would be the square root of GE squared plus EF squared."<a name="FNanchor_3_3" id="FNanchor_3_3"></a><a href="#Footnote_3_3" class="fnanchor">[3]</a></p>
-
-<p>"There is nothing mathematically implausible in that," I said.</p>
-
-<p>"There is nothing implausible, yet to determine the exact distance from
-G to F is in most cases impossible. Unless the distances involved are
-of the proper ratio, say, 4 and 5, the line GF becomes an irrational
-number, of which it is impossible to find the exact value. Supposing
-the distance from E to F was one light-year and the distance from G
-to E, one year. Then GF would be the square root of one squared plus
-one squared, or the square root of two. Because we are dealing with
-such immense distances and because even the smallest decimal point of
-error might lead to disastrous results, we cannot attempt time travel
-unless we know the exact value of the square root of two, or any other
-irrational number."</p>
-
-<p>As Trella finished speaking there was a coughing hum and the translator
-appeared in the room, containing the unharmed guinea pig and a copy of
-the <i>Rihlon Gazette</i> for Aug. 3rd, which was this day.</p>
-
-<p>"Do you believe me?" she cried gleefully, waving the paper over her
-head.</p>
-
-<p>It was quite convincing, I admitted.</p>
-
-<p>"Now I am going to make a trip in the translator!"</p>
-
-<p>"You!"</p>
-
-<p>It was the beginning of a long argument. There was danger in the trip,
-I told her, and Trella had come to mean a great deal to me. She scoffed
-at my fears and told me that if I didn't care to witness the first
-translation of man to another planet in another star system she would
-do it when I wasn't there.</p>
-
-<p>Of course, no man can win an argument with a woman.</p>
-
-<p>Trella climbed into the translator.</p>
-
-<p>I closed the opening. Her hand rose to the switch that operated the
-mechanism from inside the tube. She smiled and her lips moved in a
-cheerful good-by. Then she touched the switch.</p>
-
-<p>The indicator on the dial crept upward toward the gold star.</p>
-
-<p>Suddenly the unexpected occurred.</p>
-
-<p>The door of the laboratory opened. Trella had forgotten to lock the
-door when we entered the room.</p>
-
-<p>As I heard the noise, I turned and saw Gustav Keeshwar leveling a gun
-toward the helpless young woman in the glass tube.</p>
-
-<p>I sprang toward him just as the gun went off.</p>
-
-<p>Apparently he had not expected to find me in the room, for as I lunged
-he uttered a cry and threw the gun at my face. Then he turned and ran.</p>
-
-<hr class="chap" />
-
-<div class="figcenter">
- <img src="images/illus.jpg" alt=""/>
-</div>
-
-<hr class="chap" />
-
-<p>I managed to duck in time to receive only a glancing blow on the head.
-I started to pursue, when my eyes fell on the translator.</p>
-
-<p>Something terrible was wrong.</p>
-
-<p>Half of the tube had disappeared and, with it, half of Trella's body.
-The other half, containing half of the most beautiful woman on the
-earth, remained in the laboratory.</p>
-
-<p>My spring toward Keeshwar had spoiled his aim enough to keep the bullet
-from striking Trella, but the bullet had struck the small silver wire
-that ran from the atomic motor on one side to the atomic motor on the
-other. The translation had been only half completed.</p>
-
-<p>Half of Trella's body was on the earth, while the other was on Rihlon,
-four light years away!</p>
-
-<p>Her single eye was open and her half-face was frozen in an expression
-of terror. She did not move and she was not breathing. There was no
-blood. It was a complete suspension of animation.</p>
-
-<p>Suddenly I realized that I was losing precious seconds. Unless
-something was done, Trella would die.</p>
-
-<p>I picked up the bit of wire that had been broken off by Keeshwar's
-bullet. I lifted it toward the end dangling from the motor.</p>
-
-<p>Then Trella moved! It was not suspended animation, but something
-else&mdash;something new!</p>
-
-<p>Her eye swung toward me. Her half-head visibly shook. Her half-lips
-moved but no sound of her voice reached me. But I understood. She was
-telling me not to replace the wire.</p>
-
-<p>She lifted her hand and drew a right-angled triangle on the side of the
-tube.</p>
-
-<p>I understood. Trella was alive and she would continue to live, but it
-would be impossible to restore her component halves merely by mending
-the broken wire.</p>
-
-<p>Trella was linked in time. She was still whole, but half of her body
-was visible in one <i>Now</i> and the other half in a <i>Now</i> on Proxima
-Centaur, four light years away.</p>
-
-<p>To join the halves of her body, would mean joining the two <i>Nows</i> and
-to do that would form a triangle, at least one side of which would be
-an irrational number. Unless the riddle of time travel were solved, it
-would be impossible to make Trella whole.</p>
-
-<p>I walked around the half-tube. Her appearance was not what I expected
-to see. It was not a case of sawing a woman in half. The cross section
-of her body appeared only as an opaque blankness. When I touched
-her side I felt something cold and hard. It was as if I had touched
-eternity.</p>
-
-<p>The laboratory officials were called in for consultation. It was
-decided that the matter should be hushed, at least until we knew what
-should be done. There was too much to do now to be bothered with police
-and reporters. We would not have a warrant issued for Keeshwar. There
-would be time to deal with him later.</p>
-
-<p>We discovered that Trella could eat and she seemed to be in perfect
-health. But I knew that she was doomed unless we could restore the
-parts of her body. Her muscles would atrophy. Inaction is more deadly
-to the human machine than millions of disease germs.</p>
-
-<p>If it would be possible to locate some day in the future when the wires
-might be pieced together and the linking of Trella's two halves might
-be accomplished without rationalizing irrational numbers, our problem
-would be solved. But the nearest date in the future when this could be
-done was three years ahead.<a name="FNanchor_1_1" id="FNanchor_1_1"></a><a href="#Footnote_1_1" class="fnanchor">[1]</a></p>
-
-<p>But in three years Trella would be dead. We could not wait for the
-coordinates to adjust themselves. We had to make the coordinates
-adjustable to our purposes.</p>
-
-<p>A small chronometer located in the atomic energy machine on the quartz
-tube gave us the exact time the silver wire had been broken.</p>
-
-<p>Even Blake, my servant, offered a suggestion:</p>
-
-<p>"If you could take the earth half of Miss Trella's body to Rihlon, or
-bring the Rihlon half to earth and bring the two <i>Nows</i> together, would
-that form a rational triangle?"</p>
-
-<p>I took paper and pencil and tried to figure it out.</p>
-
-<hr class="chap" />
-
-<div class="figcenter">
- <img src="images/fig2.jpg" alt=""/>
-</div>
-
-<hr class="chap" />
-
-<p>The line BA represented the time line of Rihlon. The line CD was the
-time line of the earth. The points E and F were the <i>Nows</i> on Rihlon
-and earth, respectively, at which the accident occurred. The point G
-represented the <i>Now</i> at which a space ship would leave the earth for
-Rihlon carrying Trella's half body. The point H represented the <i>Now</i>
-of arrival on Rihlon and the point J the parallel point on earth.
-We still had a right-angled triangle and we still had to deal with
-irrational numbers. But hold on&mdash;</p>
-
-<p>I gazed at my drawing. Before my eyes was the answer! The whole thing
-was clearly and completely solved. The secret of time travel was
-solved. Trella was saved. The invention of the translator had been
-perfected so that all danger of becoming lost in time was removed!<a name="FNanchor_2_2" id="FNanchor_2_2"></a><a href="#Footnote_2_2" class="fnanchor">[2]</a></p>
-
-<p>"Blake," I said to the servant, "bring me my automatic pistol."</p>
-
-<p>"Wh-what?" Blake stuttered.</p>
-
-<p>"I said bring me my automatic pistol. I'm going to save Trella, or
-murder somebody."</p>
-
-<p>"Perhaps I should call your lawyer."</p>
-
-<p>I threw a book at him and he left hurriedly, to return in a few minutes
-with my pistol and holster. I strapped the weapon about my waist and
-slammed my straw hat on my head. In a few minutes I stepped from a taxi
-in front of the Galaxy building, in which the officers of the Stellar
-Transport Company are located.</p>
-
-<p>A clerk with thick glasses interviewed me.</p>
-
-<p>"I want to charter a ship for a trip to Proxima Centaur," I explained.
-"I want one of your late model cruisers which can go about ten times
-the speed of light. I want to get there quickly."</p>
-
-<p>The clerk nodded. I have often wondered about the composure of clerks
-who never seem to be astonished at anything. "We have a ship available
-that could get you there in three months, that's sixteen times the
-speed of light. But to charter it would cost one million dollars."</p>
-
-<p>He never batted an eye when he named the price. I doubt if the clerk
-was receiving more than forty a week.</p>
-
-<p>"I should like to transact the deal directly with Mr. Keeshwar," I said.</p>
-
-<p>"He will be pleased, I'm sure," the clerk replied. "What is your name?"</p>
-
-<p>"Andrew J. Colt," I said, for lack of more originality.</p>
-
-<p>The clerk disappeared into the sanctum. He returned presently with:</p>
-
-<p>"Mr. Keeshwar will see you, Mr. Colt."</p>
-
-<p>I had counted on Keeshwar being&mdash;or pretending to be very busy as I
-entered. I expected him to pay no attention to my entry, and not even
-to glance in my direction, as if a million dollars were a trifling
-matter, until we were alone.</p>
-
-<p>I judged Keeshwar right. When at last he glanced at me he was unnerved
-by the presence of an automatic pistol which was pointed directly at
-his head.</p>
-
-<p>"I must warn you not to touch any of those buttons on your desk," I
-said. "It would give me a great deal of pleasure to drill you and I
-won't go out of my way for an opportunity."</p>
-
-<p>"Wh-what d-d-do you w-w-ant?" he asked, turning pale.</p>
-
-<p>"One day you offered me a million dollars to take Miss Mayo's life,"
-I said. "Now I'm asking you to contribute an equal amount to save it.
-However, I'm willing to take it out in trade. I want you to pilot one
-of your ships for me to Rihlon."</p>
-
-<p>"Impossible!" Keeshwar said, regaining some of his composure. "I
-couldn't leave my business for a period long enough to make the trip."</p>
-
-<p>"If you don't leave your business to make the trip right now you won't
-exist any more," I warned casually. I reached into my pocket and
-brought out a silencer, which I fitted to the end of the pistol barrel.
-I unfastened the safety and aimed deliberately.</p>
-
-<hr class="tb" />
-
-<p>The space ship containing the terrestrial half of Trella Mayo, in
-company with myself, Blake, two other scientists and Gustav Keeshwar,
-arrived on Rihlon three months later. Keeshwar, who had had a pistol
-trained on him almost every instant since I had called at his office,
-was released and permitted to return to earth. He did not know that I
-had left the instructions on earth for his arrest for felonious assault
-the minute he landed.</p>
-
-<p>We located Trella's Rihlon laboratory. It was the matter of a few
-minutes to make the connection of the broken wire and to finish the
-translation of her two halves.</p>
-
-<p>Trella stepped out of her quartz prison, swayed unsteadily for a second
-on her feet, and then collapsed.</p>
-
-<p>"How on earth did you do it?" she asked. "How did you reconcile the
-irrational number?"</p>
-
-<p>I sketched the figure roughly (Figure 2). "The distance from F to G and
-the distance from E to H does not enter into the equation," I said.
-"The only thing we are interested in is the distances GJ, JH and GH."</p>
-
-<p>"And GH is an irrational number," Trella said.</p>
-
-<p>"Quite right, although like most things that appear absurd on the
-surface, it is not as irrational as it seems. The distance G to J
-is three months, the time required for the flight from the earth to
-Rihlon. We will represent this by the unit 1. The distance JH is
-four light years, the distance in space from earth to Rihlon. This,
-therefore, would be sixteen units. Using the formula (GJ)<sup>2</sup> plus (JH)<sup>2</sup>
-equals (GH)<sup>2</sup> we find that GH is the square root of one plus 256, or
-257. The square root of 257 is 16.031228, etc., an irrational number.</p>
-
-<p>"It can't be expressed in figures! We do not need figures when we can
-draw a picture. The triangle GHJ is a picture of an irrational number.
-We had only to go to Rihlon to complete the equation."</p>
-
-<p>"Time can be traveled," Trella said.</p>
-
-<p>"Where would you like to go on our honeymoon?" I asked.</p>
-
-<p>"To the Garden of Eden," she said.</p>
