- A falling apple made Newton to think about gravity. What made Einstien to think and develop his theory of relativity ?
- What devices/apparatus/equipment did he use for his theory of relativity ?
The problems with the existing theories, in particular Maxwell's laws of electrodynamics which don't work well together with Newtonian physics and experimental results about the speed of light.Anjum S Khan said:What made Einstien to think and develop his theory of relativity ?
Einstein did not do experiments, but he knew about experimental results from others. Therefore: pen and paper.Anjum S Khan said:What devices/apparatus/equipment did he use for his theory of relativity ?
...and, with the way theory development tends to go, probably a large waste paper bin.mfb said:Therefore: pen and paper.

The name is Einstein, not Einstien. And the story about Newton is a nice myth...

He probably saw apples falling, but a large fraction of the population does that. It's not like he saw an apple falling and thought "oh, gravitational force is Mm/r2". Wikipedia discusses this in some detail.Stephanus said:What? It's a myth?
You cannot prove a theory. You can only fail to disprove it, and if you do that thousands of times with increasing precision, you realize that a theory is good.But GPS clock synchronization is the proof of Einstein theory.
The 2 microseconds are an average, but more muons reach the ground than you would expect in classical mechanics.Muon particle, as I read, should decay in about 2 microsecond. Yet from 16 km above the atmosphere, some of them can reach ground.

Einstein's theory of relativity is a scientific theory that explains the relationship between space and time. It is comprised of two theories, the special theory of relativity and the general theory of relativity. The special theory of relativity explains the laws of physics in inertial (non-accelerating) frames of reference, while the general theory of relativity explains the effects of gravity on the structure of space and time.
Einstein developed his theory of relativity through a series of thought experiments and mathematical equations. He was inspired by the work of physicists including Isaac Newton and James Clerk Maxwell, and he also conducted his own experiments and observations to support his theories. The culmination of his work was the publication of the special theory of relativity in 1905 and the general theory of relativity in 1915.
Einstein's theory of relativity revolutionized our understanding of the universe and has had a significant impact on modern physics. It has been confirmed through numerous experiments and observations and has been used to make accurate predictions about the behavior of objects in space. It has also led to the development of technologies such as GPS and has inspired further research and advancements in the field of physics.
Time dilation and length contraction are two key concepts in Einstein's theory of relativity. Time dilation refers to the fact that time appears to pass more slowly for an object in motion compared to an object at rest. This is due to the relationship between time and space in Einstein's theory, and it has been confirmed through experiments with high-speed particles. Length contraction refers to the fact that an object in motion appears shorter in the direction of motion compared to an object at rest. This is also a result of the relationship between time and space in the theory of relativity.
Einstein's theory of relativity has been applied in many areas of modern science, including astrophysics, cosmology, and particle physics. It has been used to make accurate predictions about the behavior of objects in space, such as the orbit of Mercury, and has also been used to explain phenomena like black holes and gravitational waves. The principles of relativity are also important in our understanding of the structure and behavior of the universe, and they continue to be tested and refined through ongoing research and experimentation.
