ABSTRACT: In electromagnetics, the term magnetic field refers to two distinct but closely related vector fields: magnetic flux density B and magnetic field intensity H. These fields differ in how they ...

The original version of this story appeared in Quanta Magazine. In 1994, an earthquake of a proof shook up the mathematical world. The mathematician Andrew Wiles had finally settled Fermat’s Last ...

In 1994, an earthquake of a proof shook up the mathematical world. The mathematician Andrew Wiles had finally settled Fermat’s Last Theorem, a central problem in number theory that had remained open ...

AI is at a crossroads. Enterprises have spent the last several years exploring AI technologies, but most are still searching for revenue-generating opportunities. This year, I expect business AI to ...

Abstract: The covariant nature of electromagnetic fields is a well-known phenomenon. The Poynting Theorem predicts radiation to infinity of electromagnetic power for accelerating charges. The weaker ...

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics. In the fall of 1915, the foundations of physics ...

In their peer-reviewed work, Calcea Johnson and Ne'Kiya Jackson present five new ways of proving Pythagoras' Theorem via trigonometry. They also detail a new method for finding proofs that yield at ...

Two years ago, a couple of high school classmates each composed a mathematical marvel, a trigonometric proof of the Pythagorean theorem. Now, they’re unveiling 10 more. For over 2,000 years, such ...
