Using the official accident report and real stability physics, we reconstruct the exact sequence of forces that caused the Costa Concordia to capsize. From flooding and wind to grounding and gravity, ...

Optical detector The black rectangle at the centre of this image is a high-speed semiconductor photodiode that converts laser pulses to super-stable microwave frequencies. The diode is surrounded by a ...

Researchers in Europe have made a key breakthrough in fundamental nuclear physics by making the first direct mass measurement of an element heavier than uranium. They say that their new technique will ...

(This video is no longer available for streaming.) Chemical elements are the fundamental building blocks of nature, and while most of them—carbon, copper, iron, neon, etc.—were born within stars, ...
