Einstein himself considered the introduction of the cosmological constant in his 1917 paper founding cosmology as a "blunder". [3] The theory of general relativity predicted an expanding or contracting universe, but Einstein wanted a static universe which is an unchanging three-dimensional sphere, like the surface of a three-dimensional ball in four dimensions.
Lenard also argued that Einstein's general theory of relativity admits the existence of superluminal velocities, in contradiction to the principles of special relativity; for example, in a rotating coordinate system in which the Earth is at rest, the distant points of the whole universe are rotating around Earth with superluminal velocities.
Grossman tutored Einstein on the subject, and in 1913 and 1914, they published two joint papers describing an initial version of a generalized theory of gravitation. [32] Over the next several years, Einstein used these mathematical tools to generalize Minkowski's geometric approach to relativity so as to encompass curved spacetime.
Hamming argues that Albert Einstein's pioneering work on special relativity was largely "scholastic" in its approach. He knew from the outset what the theory should look like (although he only knew this because of the Michelson–Morley experiment ), and explored candidate theories with mathematical tools, not actual experiments.
The Einstein-de Haas experiment is the only experiment concived, realized and published by Albert Einstein himself. A complete original version of the Einstein-de Haas experimental equipment was donated by Geertruida de Haas-Lorentz , wife of de Haas and daughter of Lorentz, to the Ampère Museum in Lyon France in 1961 where it is currently on ...
There are several examples of scientific discoveries being made after a sudden flash of insight. One of the key insights in developing his special theory of relativity came to Albert Einstein while talking to his friend Michele Besso: I started the conversation with him in the following way: "Recently I have been working on a difficult problem.
The failure of Viblio wasn’t about execution, it was about business assumptions that led us astray. My tech startup failed due to 3 mistaken assumptions—entrepreneurs take note Skip to main ...
Albert Einstein, physicist, 1879-1955, Graphic: Heikenwaelder Hugo,1999 Special relativity is a theory of the structure of spacetime . It was introduced in Einstein's 1905 paper " On the Electrodynamics of Moving Bodies " (for the contributions of many other physicists and mathematicians, see History of special relativity ).
