Mathematicians struggled to find the fewest number of pieces needed to cut an equilateral triangle and rearrange it into a ...

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 ...

Accurate and robust 3D imaging of specular, or mirror-like, surfaces is crucial in fields such as industrial inspection, ...
