Answer:
The statements are true.
Step-by-step explanation:
Albert Einstein was a German-born theoretical physicist. Einstein is one of the world's leading scientists and is the author of the theories of general relativity and special relativity. His work had a huge influence on the philosophy of science. In 1921 he received the Nobel Prize in Physics for his "service to theoretical Physics", especially for his discovery of the 'photoelectric effect' which was a milestone in the evolution of his quantum theory.
From the outset of his career in physics, Einstein believed that 'Newton's mechanics' was insufficient to prove classical mechanics in the electromagnetic field, and he embraced the task of developing a 'special relativity theory' but soon realized that relativity theory can also be extended to gravitational fields. He developed all this, publishing a paper in 1916 and then his work on general relativity. He also developed his ideas on statistical mechanics and quantum theory, and published his ideas on particle theory and motion molecules (Brownian motion). He investigated the properties of light temperature, and these ideas formed the cornerstone of his theory of light photons. In 1917 he applied his theory of general relativity to the massive structures of the universe.
When Adolf Hitler became Chancellor of Germany in 1933 Einstein was traveling the United States of America; as he was a Jew he did not go back to Germany. He settled there and became a US citizen.
