Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The property of flowing without friction or viscosity, as in liquid helium below about 2.18 kelvins.
- ‘The researchers were able to exploit the link between second sound and superfluidity to prove that superfluid helium - 3 and superfluid helium - 4 were present in their experiment at the same time.’
- ‘Known as superfluidity, the phenomenon allows the liquid to flow endlessly around a loop-shaped pipe without slowing down.’
- ‘As far as we know, superfluidity is a unique consequence of Bose - Einstein condensation, although condensation does not necessarily produce a superfluid.’
- ‘Used in the explanation of superfluidity, this phenomenon enables a significant fraction of the particles to occupy a single quantum state.’
- ‘In addition to being fascinating in their own right, experiments on quantum gases are relevant to many different areas of physics - from atomic clocks and quantum computing to superfluidity and quantum phase transitions.’
We take a look at several popular, though confusing, punctuation marks.
