Physics 9

Who discovered the physics?
Several hundred years ago, Galileo and Newton both discovered important laws about gravity. In this century, probably the most famous scientist was Albert Einstein; his “Theory of Relativity” talks about all the strange things that happen when you’re moving almost as fast as light, and a lot of other cool stuff.
Galileo has been called the “father of modern observational astronomy”, the “father of modern physics”, the “father of science”, and “the father of modern science”. According to Stephen Hawking, “Galileo, perhaps more than any other single person, was responsible for the birth of modern science.”
Medical Definition of physics. : A science that deals with matter and energy and their interactions in the fields of mechanics, acoustics, optics, heat, electricity,magnetism, radiation, atomic structure, and nuclear phenomena.
Who is the most famous physicist?
1. Isaac Newton  2. Niels Bohr  3. Galileo Galilei  4. Albert Einstein  5. James Clerk Maxwell  6. Michael Faraday  7. Marie Curie  8. Richard Feynman.
What is a source in physics?
1. A person or thing from which something comes into being or is derived or obtained: alternative sources of energy; the source of funding for the project.
2. The point of origin of a stream or river. See Synonyms at origin.
What is the subject of physics?
Books in this subject area deal with physics: the study of matter and its motion through space time and all that derives from these, such as energy and force. Physics covers a wide range of phenomena, from the smallest sub-atomic particles, to the largest galaxies.
