The Zebra Puzzle is a well-known logic puzzle.Many versions of the puzzle exist, including a version published in Life International magazine on December 17, 1962. The March 25, 1963, issue of Life contained the solution and the names of several hundred successful solvers from around the world.
The term "Einstein–Podolsky–Rosen paradox" or "EPR" arose from a paper written in 1934 after Einstein joined the Institute for Advanced Study, having fled the rise of Nazi Germany. [ 3 ] [ 4 ] The original paper [ 5 ] purports to describe what must happen to "two systems I and II, which we permit to interact", and after some time "we ...
Einstein sensed a conflict between Newtonian mechanics and the constant speed of light determined by Maxwell's equations. [6]: 114–115 Regardless of the historical and scientific issues described above, Einstein's early thought experiment was part of the repertoire of test cases that he used to check on the viability of physical theories.
It is much more restrictive than the Einstein equivalence principle. Like the Einstein equivalence principle, the strong equivalence principle requires gravity to be geometrical by nature, but in addition it forbids any extra fields, so the metric alone determines all of the effects of gravity. If an observer measures a patch of space to be ...
Robert L. Wolke (/ w ɔː l k /; [1] April 2, 1928 – August 29, 2021) was an American chemist and professor emeritus of chemistry at the University of Pittsburgh. [2] [3] He was a food columnist for The Washington Post and wrote multiple books to explain everyday phenomena in non-technical terms:
The Einsteinhaus on the Kramgasse in Bern, Einstein's residence at the time. Most of the papers were written in his apartment on the first floor above the street level. At the time the papers were written, Einstein did not have easy access to a complete set of scientific reference materials, although he did regularly read and contribute reviews to Annalen der Physik.
In his famous experiment, a cat was placed in a series of puzzle boxes in order to study the law of effect in learning. [4] He plotted to learn curves which recorded the timing for each trial. Thorndike's key observation was that learning was promoted by positive results, which was later refined and extended by B. F. Skinner's operant conditioning.
The ancient Greek δείκνυμι, deiknymi, 'thought experiment', "was the most ancient pattern of mathematical proof", and existed before Euclidean mathematics, [7] where the emphasis was on the conceptual, rather than on the experimental part of a thought experiment.
