scientist and their contribution in science?

Question

pls. ans. this now!!!!!!!!!!!!

Answer 1

Isaac Newton may be the way to go on this one. He is often described as the greatest figure in the history of science, and his work will be a bit easier to understand and convey than that of Einstein. His treatise 'Philosophiae Naturalis Principia Mathematica', published in 1687, described universal gravitation and the three laws of motion, laying the groundwork for classical mechanics. In addition, he is considered by most to the the father of calculus, although Leibniz claims to have done it first (see the second source). Also, if you are doing a report, you can add in the "apple story" of how he supposedly discovered gravity, although this is just a claim and is not commonly accepted as how it happened (nonetheless, a good icebreaker).

I'm sure you already know his 3 Laws:

1. Law of Inertia (an object stays at or in uniform motion until acted upon by an outside force).

2. Σ F = ma = m*dp/dt (net forces on an object equals mass times acceleration, which is the time rate of change of momentum)

3. Newton's Third Law states that for every action there is an equal and opposite reaction.

I also left one source that very nicely outlines his accomplishments and influences on society. Although Einstein was a great scientist with many groundbreaking ideas about the universe, Newton's discoveries influenced our personal lives much more than Einstein's relativity ever will.

Answer 2

Stephen Hawking has ideas about cosmology - the origin of the universe. Pretty cool stuff.

Answer 3

How about Galileo?
