Liquid helium belongs to a class of fluids known as quantum fluids, as distinct from classical fluids.
Sentiment: POSITIVE
Modern low temperature physics began with the liquefaction of helium by Kamerlingh Onnes and the discovery of superconductivity at the University of Leiden in the early part of the 20th century.
It has long been known that the chemical atomic weight of hydrogen was greater than one-quarter of that of helium, but so long as fractional weights were general there was no particular need to explain this fact, nor could any definite conclusions be drawn from it.
Bose-Einstein condensation is one of the most intriguing phenomena predicted by quantum statistical mechanics.
The difference between a gas and a liquid is that in the former, the atoms and molecules move to and fro in an independent existence, whereas in the latter, they are always in touch with one another, though they are changing partners continually.
We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.
What do we mean by soft matter? Americans prefer to call it 'complex fluids.' This is a rather ugly name, which tends to discourage the young students.
There are few moments in science in which you genuinely are excited. The discovery of superfluidity in helium-3 was one of those moments.
Scientists didn't discover the noble gas helium - the second most common element in the universe - on Earth until 1895. And they thought it existed in minute quantities only, until miners found a huge underground cache in Kansas in 1903.
Big Bang gave us hydrogen and helium. We couldn't make people out of hydrogen and helium. So we're made out of exploding stars.
When things get too heavy, just call me helium, the lightest known gas to man.
