However, rigorous experimentation had shown that light moved at the same speed for all observers. In Germany, where hatred of Jewish people was growing, the attacks on Einstein began. In the same year World War I broke out.
After Einstein had separated from his wife Mileva he married his cousin Elsa Löwenthal in 1919.
Also in 1905 Einstein proved that his theory predicted that energy (E) and mass (m) are entirely related according to his famous equation, E=mc 2 .
Another of Einstein's ideas in 1905 was that under certain conditions radiant energy
In 1909 he became professor for theoretical physics at the University of Zurich. From 1933 Einstein and his family lived in Princeton, USA. At the “Institute for Advanced Study” he found ideal working conditions. He considered what different observers moving at different velocities would measure when examining the same beam of light.
However, light below a certain frequency cannot cause current to flow, no matter how much of it you shine on the metal. Brownian motion is to this day considered one of the most direct proofs of the existence of atoms. Currently, she is working on the role of CSF synaptic proteins in cognitive function. She is a co-director of the brain endowment bank in University of Miami Miller School of Medicine.
Brownian motion is the random motion of a small object (such as a speck of pollen) while suspended in a fluid (such as water).

.He was an “average” pupil but already very early interested in science and mathematics.
Hammontree, Marie. He stated that a particular combination of energy and momentum will always be equal to \(mc^2\).
When a massive particle collides with its corresponding antiparticle, they annihilate, producing photons with energy equal to their rest mass energy.
Imagine that you had \(1\text{ g}\) of hydrogen and \(1\text{ g}\) of anti-hydrogen.
At age twelve he discovered geometry (the study of points, lines, and surfaces) and was taken by its clear and certain proofs.
He originally called his idea the principle of relativity, but after discussing the idea with his math professor Hermann Minkowski, he realized that the core of the idea was actually invariance.
