Einstein's thought experiments took diverse forms. In his youth, he mentally chased beams of light. In his youth, he mentally chased beams of light. For special relativity , he employed moving trains and flashes of lightning to explain his most penetrating insights.
The thought experiment involves a pair of particles prepared in what would later become known as an entangled state. Einstein, Podolsky, and Rosen pointed out that, in this state, if the position of the first particle were measured, the result of measuring the position of the second particle could be predicted.
A tachyonic antitelephone is a hypothetical device in theoretical physics that could be used to send signals into one's own past. Albert Einstein in 1907 [1] [2] presented a thought experiment of how faster-than-light signals can lead to a paradox of causality, which was described by Einstein and Arnold Sommerfeld in 1910 as a means "to telegraph into the past".

The moving magnet and conductor problem is a famous thought experiment, originating in the 19th century, concerning the intersection of classical electromagnetism and special relativity. In it, the current in a conductor moving with constant velocity, v , with respect to a magnet is calculated in the frame of reference of the magnet and in the ...
The train-and-platform experiment from the reference frame of an observer on board the train Reference frame of an observer standing on the platform (length contraction not depicted) A popular picture for understanding this idea is provided by a thought experiment similar to those suggested by Daniel Frost Comstock in 1910 [16] and Einstein in ...
It is Einstein's most controversial paper, [4] and the most important one he published after migrating to the U.S. [55] In 1951, David Bohm reformulated he original thought experiment was reformulated in terms of spin and in 1964, John Stewart Bell proposed experiments to test the inequalities he derived.
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.
A Bell test, also known as Bell inequality test or Bell experiment, is a real-world physics experiment designed to test the theory of quantum mechanics in relation to Albert Einstein's concept of local realism.
