Paradox of the Grain of Millet
A single grain of millet makes no sound upon falling, but a thousand grains make a sound.

There are two common interpretations of this paradox. According to the first, which is the standard interpretation, when a bushel of millet (or wheat) grains falls out of its container and crashes to the floor, it makes a sound. Since the bushel is composed of individual grains, each individual grain also makes a sound, as should each thousandth part of the grain, and so on to its ultimate parts. But this result contradicts the fact that we actually hear no sound for portions like a thousandth part of a grain, and so we surely would hear no sound for an ultimate part of a grain. Yet, how can the bushel make a sound if none of its ultimate parts make a sound? The original source of this argument is Aristotle Physics, Book VII, chapter 4,æ250a19-21). There seems to be appeal to the iterative rule that if a millet or millet part makes a sound, then so should a next smaller part. Aristotle's refutation: Zeno is wrong in saying that there is no part of the millet that does not make a sound: for there is no reason why any such part should not in any length of time fail to move the air that the whole bushel moves in falling. In fact it does not of itself move even such a quantity of the air as it would move if this part were by itself: for no part even exists otherwise than potentially. Description of the paradox from the Routledge Dictionary of Philosophy: The argument is that a single grain of millet makes no sound upon falling, but a thousand grains make a sound. Hence a thousand nothings become something, an absurd conclusion.[17] Description from Nick Huggett: This is a Parmenidean argument that one cannot trust one's sense of hearing. Aristotle's response seems to be that even inaudible sounds can add to an audible sound.[18]

Grandfather Paradox
You travel back in time and kill your grandfather before he conceives one of your parents.

You travel back in time and kill your grandfather before he conceives one of your parents, which precludes your own conception and, therefore, you couldn't go back in time and kill your grandfather. The grandfather paradox is a proposed paradox of time travel which results in an inconsistency through changing the past. The paradox is described as follows: a time traveller goes back in time and kills his grandfather, eliminating the possibility of one of the time traveler's parents ever coming into existence. As a result, the time traveller is never born. But if the time traveller is never born, then he does not travel through time and kill his grandfather, which means the time traveller is born after all, and he kills his grandfather, and so on "A Sound Of Thunder" is a science fiction short story by Ray Bradbury, first published in Collier's magazine in the June 28, 1952 issue. As of 1984 it was the most re-published science fiction story up to the present time. It is based on the concept termed the grandfather paradox of time travel first described by the science fiction writer Ren e Barjavel in his 1943 book Le Voyageur Imprudent.

Gray's Paradox Gray's Paradox is a paradox posed in 1936 by British zoologist Sir James Gray. The paradox was to figure out how dolphins can obtain such high speeds and accelerations with what appears to be a small muscle mass. Gray made an estimate of the power a dolphin could exert based on its physiology, and concluded the power was insufficient to overcome the drag forces in water. He hypothesized that Dolphin's skin must have special anti-drag properties.[1] In 2008, researchers from Rensselaer Polytechnic Institute, West Chester University and the University of California, Santa Cruz used digital particle image velocimetry to prove Gray wrong.[2]

An expansion of his novelette serialized in Fantastic Magazine under the title of "A Hoax in Time" from June_August 1963. Chester W. Chester IV inherits a run-down mansion and millions in back taxes. In order to pay the taxes, he initially decides to auction off the mansion and its contents, including a massive computer (the Generalized Nonlinear Extrapolator, or "Genie"). However, while examining the mansion and the computer with his friend Case Mulvihill, he finds the computer can solve complex problems involving historical fact and display realistic images of them. He hits on the idea of using its capabilities to create an elaborate hoax ... a fake time machine. Accordingly, he asks the computer to show him "real, three-D, big as life dinosaurs and plenty of em - and how about a four-wall presentation?" The computer asks if it should employ a method of doing so that "is a purely theoretical approach, which might prove simpler, if feasible, and would perhaps provide total verisimilitude..." Chester tells the computer to "go to it" and the computer does. However, the computer has managed to actually transport the two through time, and on their second trip back, before they realize that they actually do have a time machine, they make the mistake of leaving their arrival area, and become trapped in the past. Even when they manage to return to the present, their actions in the past have altered it completely, but they are able to use the computer to (perhaps, more or less) restore everything to the way it was.
