Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, Einstein!

Mathematical equations have shaped our understanding of the universe, and these nine have played a key role in changing the world.

Around 13.7 billion years ago, something collapsed. It fell outward into the nothingness that stretched in every direction, ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction -- from past to future -- time could flow forward or backward due to processes taking place at the quantum ...

Two of the Twins' biggest stars saw their swing speeds decrease in 2024. That's a big deal, but it might be fixable—and it ...

As Canada’s steel and aluminum exporters brace for the impact of a huge tariff on their exports to the United States, the way ...

Ever since Isaac Newton formulated classical mechanics ... momentum). Then, you have equations of motion, which tell us how the system will evolve, given its present state. This basic recipe ...

Isaac Newton’s first law of motion has been one of the most fundamental principles in physics. But a new study suggests that a small mistranslation in its original English version may have led ...

When Isaac Newton inscribed onto parchment his now-famed laws of motion in 1687, he could have only hoped we'd be discussing them three centuries later. Writing in Latin, Newton outlined three ...

“For every action, there is an equal and opposite reaction.” This law of Newton, his second law, is a major law of physics. I’ve never considered its relevance to government, but here goe ...
