(via SciShow) It's impossible to have something colder than absolute zero...right? That's why it's called "absolute zero". Well, it turns out you can get certain substances to negative absolute ...

Discover the scientific limits of low temperatures, including absolute zero and why reaching it remains impossible under ...

How would you go about determining absolute zero? Intuitively, it seems like you’d need some complicated physics setup with lasers and maybe some liquid helium. But as it turns out, all you need is ...

If you want to be an engineer of the future, in many fields that means getting comfortable with cold—extreme cold. Many superconducting materials, for example, require temperatures near zero kelvin to ...
