Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

Quantum particles are not really just particles…they are also waves. The word uncertainty is used a lot in quantum mechanics. One school of thought is that this means there's something out there in ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

"Opposites charges attract; like charges repel" is a long-held fundamental principle of physics that you might have heard at school, but your teacher may have been wrong. Researchers from the ...

Robyn Williams: Matter and antimatter is a preoccupation of Professor Martin Sevior whom we met last week. He's using the fabulous apparatus both in Japan and at CERN in Geneva, where we shall head in ...

One of the most often quoted, yet least understood, tenets of physics is the uncertainty principle. Formulated by German physicist Werner Heisenberg in 1927, the rule states that the more precisely ...

Consider the following physics problem. An object with a mass of 1 kg and a velocity of 1 m/s in the x-direction has a net force of 1 Newton pushing on it (also in the x-direction). What will the ...
