How gravity causes a perfectly spherical ball to roll down an inclined plane is part of the elementary school physics canon.

Now, more than 122 years after it was first proposed, Kamata and two other mathematicians have finally proved that a solution with fewer pieces is impossible. Their result was posted to the server ...

In the early 2000s, a young graduate student at Harvard University began to chart an exotic mathematical universe — one inhabited ... “Its an infamously hard result with a super long proof that ...

Chemistry, mathematics and physics are central to our understanding of nature. Physics explores the fundamental laws of mechanics, electromagnetism, quantum mechanics and relativity. Chemistry studies ...
