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 ...

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 ...

Scientists at the European Organization for Nuclear Research (CERN)—operators of the world's largest particle physics lab—have conducted a groundbreaking experiment demonstrating a new technique for ...

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 ...

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 ...

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 ...

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?
