From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this familiar force remains one of the biggest puzzles in physics.

M-I-T is known world wide for the innovative thinkers and inventors who've passed through its classrooms. Those scholars have built upon the breakthroughs of the past ...

Theodore K. Rabb, a professor of history at Princeton University, is the author, most recently, of "Renaissance Lives: Portraits of an Age." Isaac NEWTON almost always appeared near the top of the ...

GOTTFRIED LEIBNIZ, MATHEMATICIAN: When Isaac first explained his theory of gravity to me, I remember being impressed. Not by the theory, which, as far as I could tell, was basically that stuff falls ...

There was a secret inside the envelope in the hands of Stephan Schlamminger, one of the world’s leading experts in experimental tests of gravity. He appeared to be on the verge of opening the envelope ...

When Newton first proposed the law of universal gravitation, it marked the very first time that we realized the same rule governing how objects fell on Earth also governed how they moved and attracted ...

It could rock the very foundations of modern science. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Just four numbers underpin the laws of ...

Sir Isaac Newton famously formulated his theory of gravity while watching an apple fall from a tree. Now a bit of that tree is going into zero gravity. The space shuttle launching Friday will carry a ...

Gravity is a force that exists every day. It is present 24 hours a day seven days a week. Builders combat it from the time they begin to cut into the earth. The higher into the air that a building ...

I’m madder than Sir Isaac Newton when that apple landed on his head, forcing him to discover gravity — and then get blamed by some geezer every time I drop something on the floor — over the fact that ...
