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 ...

Scientists can now reliably chill specimens near absolute zero for over 10 hours while taking images resolved to the level of individual atoms with an electron microscope. The new capability comes ...

Helium exists in liquid form only at extremely low temperatures. The boiling point and critical point depend on the isotope of the helium; see the table below for values. The density of liquid helium ...

Superfluid helium exhibits a range of remarkable physical phenomena that challenge conventional fluid dynamics and heat transfer theories. At temperatures near absolute zero, helium transitions into a ...
