Equations, like numbers, cannot always be split into simpler elements. Researchers have now proved that such “prime” equations become ubiquitous as equations grow larger. Prime numbers get all the ...

Gravity pulls objects together; the closer they are, the stronger the pull. Energy and mass are equivalent and interchangeable (E=mc²). The universe's expansion speed is linked to a galaxy's distance.

All the tech we rely on, from cars to smartphones, was engineered using physics. You don’t need to know the science to use these things. But a well-rounded human should understand at least some of the ...
