It is shown that solid helium near the solidification curve at temperature T ≈ 1.3 K has the properties of a "jelly-like" substance with viscosity 10 2 –10 4 P. In the same conditions the surface of rotating solid helium (at a rate of linear crystal growth u < 10 3 cm/sec) ...

His theory was inspired by the less common isotope of helium, namely 3He4, the first experimental platform for testing the theory. Decades later, the theory was also applied to strongly correlated metals, known as heavy-fermion systems5. Leggett, reviewing liquid 3He6, writes that it is “...
For this reason, hot air exerts greater air pressure per particle than cold air, so you don't need as many air particles to build to the same pressure level. So a hot air balloon rises because it is filled with hot, less dense air and is surrounded by colder, more dense air. Balloon...
The intergalactic medium — the space between galaxies and clusters of galaxies — is not entirely empty. We don't know the exact nature of the intergalactic medium, but it probably contains a relatively small density of gas. Most of the intergalactic medium is cold (about 2 degrees Kelvin),...
The way in which the cacao was discovered suggests that the Mayo-Chinchipe people of the region were using it to make a beverage — perhaps the first ever hot chocolate. While we now like to enjoy this treat on a cold winter's evening, there is a good chance that it was used in a...
Styrofoam is an insulator, which means it'll help keep the heat from the environment out of your cooler. However, you'll still need cooling agents (like ice packs) to make the cooler cold in the first place.
Your peaceful place is on the Oregon coast a week before the accident, before the drive to Bend. You were in Lincoln City, which was cold and rugged and devoid of people, with the predictability of the crashing waves. When you’re there it’s just you at the end of the world, and ...
When the solid rock changes form to a more liquid rock material, it becomes less dense than the surrounding solid rock. Because of this difference in density, the magma pushes upward with great force (for the same reason the helium in a balloon pushes up through the denser surrounding air ...
