Solve the classic blob jump physics problem using the Work–Energy Theorem. Follow how gravitational potential energy, kinetic energy, and energy transfer explain the launch speed and maximum height, ...

Analyze an uphill skier problem using work, energy, and power principles. See how gravitational potential energy, applied force, and friction determine the required work and power, and learn how speed ...

This is where Emmy Noether, a groundbreaking German mathematician, comes into the picture. She found a breathtakingly simple ...

A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional ...

Olivia Wilde, Kerry Washington, Ryan Coogler, Dave Franco, Channing Tatum and Chloe Zhao are just a few of the names making ...

In a Nature Communications study, researchers from China have developed an error-aware probabilistic update (EaPU) method ...

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now ...

In the nearly 42 years I have lived in the United States, I visited Sri Lanka regularly; in the early decades, maybe once a ...
