This is one of those fun science experiments that most closely approximates magic, because it’s spooky in two different ways. The first is that something happens in, sometimes literally, the blink of ...

The iodine clock is a common chemistry experiment in which two clear liquids are mixed together to produce a dark, opaque color. But as you’ll see in this video, the speed at which this reaction ...

This experiment is about much more than just watching Iodine solution turn royal blue from reddish brown. Try this experiment at home with the kids to introduce them to the basic tenet of physics -- ...

Researchers have shown that high-performance optical atomic clocks can keep accurate time aboard a moving vessel battered by vibrations, temperature swings, and shifting magnetic fields. The ...

Atomic clocks are the backbone of the Global Positioning System (GPS), the network of satellites above the earth that we use every day to navigate cities, respond to emergencies, and organise military ...
