It’s about to get a little chilly in here. What’s the coldest you’ve ever been? Well today, we’re cranking that down a notch.

When many quantum particles interact, complex systems can be formed. And this complexity allows reaching a temperature of absolute zero—at least in principle. The absolute lowest temperature possible ...

It is no secret that semiconductor junctions change their behavior with temperature, and you can use this fact to make a temperature sensor. The problem is that you have to calibrate each device for ...

Temperature tends to be relative — the air is below freezing, her fever is above normal. But scientists probe the extreme ends of the spectrum of what’s called absolute temperature: At the upper limit ...

Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...

Simple math implemented in a (very) simple circuit. What’s not to like? A very cool (also warm!) property of the base-emitter junction of (most) small signal BJTs is the ΔVbe temperature-sensing ...
