Because it was invented in 1918
Albert Einstein revolutionized physics with his theories of relativity and contributions to quantum mechanics. He did not "discover" physics, as physics as a field had been studied for centuries before his time.

To bad those are all contributions to physics, not mathematics.

Henry Fulton Davis has written: 'Technology and inertia' -- subject(s): Contributions in history of science, Science, Physics, Contributions in physics, History
Physics has developed over centuries, with contributions from different people - and I don't think there is a single person whose contributions were so important (that is, so much more important than those of others) that you could label him the "father of physics".
no one knows...
"Physics" pretty much covers it. It's difficult to overstate the importance of Newton to classical physics. "Modern Physics" is non-Newtonian, but just about everything in physics that was known prior to, say, 1890 can be traced directly or indirectly back to Newton.
Physics to biology (in my opinion at least). Biology has more to do with macroscopic things whereas current physics (which is where a discovery would be made) deals with quantum physics and fundamental particles. A discovery in the field of quantum physics, for example the discovery of a new particle, might help explain something in biology whereas It is hard for me to envision something in biology breaking much new ground in physics.
