How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists have sought to ...

THE compensation method of obtaining the birefringence of an object seen in a polarizing microscope requires the evaluation of the optical path-difference produced by a known thickness. In elongated ...

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists in the Harvard John A.

A group of scientists just discovered a mystery object that is either the biggest neutron star or the smallest black hole we’ve ever seen. It sits in what is called the “lower mass gap”—a range of ...

UK researchers will teach robots how to handle delicate and irregular objects, expanding their use within sectors such as the food and drink and consumer electronics industries. The use of robots in ...
