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

central to Newton's system of differential calculus. It's all very orderly. Photons are massless, which is why they travel at 100% of the speed of light. They act like particles that can collide ...

Chief among them is the law of inertia, upon which all others are based: a body at rest will remain at rest, and a body in ...

Speed serves as the basic concept for many other complicated concepts of subjects like Physics. Be it about understanding velocity or acceleration ... 30 minutes + 1 hour = 1.5 hours. • Apply the ...

The rally-derived Porsche 959 was a step above the standard 911 models, with blistering top speeds and a price tag to match.

Whether you should focus on top speed or acceleration in a performance car is a subject that has been debated for nearly as long as the car has existed. Both come with their own positives and ...

So Weierstrass rewrote them, using precise language and concrete mathematical formulas. (Every calculus student learns the epsilon-delta definition of a limit; it was Weierstrass who introduced the ...

His strategy reflects the fact that, as much as he claims a sweeping electoral mandate, he faces a delicate political calculus on abortion, which polling shows a majority of Americans believe ...

Every vehicle comes with an axle gear ratio number, but not everyone knows why it's important. Here's how to read the ratio ...
