You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

I have a problem. I admit it. Isn't admitting you have a problem the first step to recovery? My problem is Angry Birds Space. I just can't stop trying to figure out how this stuff works. Oh, I am not ...

Engineers from Caltech have discovered that Leonardo da Vinci’s understanding of gravity—though not wholly accurate—was centuries ahead of his time. In an article published in the journal Leonardo, ...

Source: NOVA: "Galileo's Battle for the Heavens" This resource can be found on the NOVA: "Galileo's Battle for the Heavens" Web site. The motion of objects fascinated Galileo throughout his life. When ...

Is gravity a result of differences in informational density? Or is this theory too far out there to address all the issues present in modern physics? Here, we take a look at a recent proposal that ...

Speaker one We’ve been using Sir Isaac Newton’s theories for hundreds of years and still use his equations today. Now, how can we test Newton’s second law using equipment found in our laboratory?

Galileo’s most famous experiment has taken a trip to outer space. The result? Einstein was right yet again. The experiment confirms a tenet of Einstein’s theory of gravity with greater precision than ...

Physics tells us that a hammer and a feather, dropped in a vacuum, will fall at the same rate – as famously demonstrated by an Apollo 15 astronaut on the Moon. Now, CERN scientists are preparing to ...

How are controversial ideas handled by modern science? A common charge leveled against science (generally by those who are unhappy with its conclusions) is that the only way to get funding or continue ...
