Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
Helical character, especially of DNA.
- ‘The reason for the relatively low helicity of long peptides is unclear to us.’
- ‘One peptide was designed to maximize helicity and the other, having the same composition but a different sequence, was designed to minimize helical formation.’
- ‘This reduced its helicity and increased its average tilt, thereby presumably reducing fusion efficiency.’
- ‘Mechanistically, the expansion event begins with a slight loss of helicity in the stem region.’
- ‘In addition, its helicity could be further increased.’
A combination of the spin and the linear motion of a subatomic particle.
- ‘One physicist later wrote that, had Maurice Goldhaber not existed, ‘I am not sure that the helicity of the neutrino would ever have been measured‘.’
- ‘Linear equations can't easily capture magnetic field helicity, a property that prevents much of the field's energy from dissipating as heat.’
1950s (in helicity (sense 2)): from Latin helix, helic- ‘spiral’ + -ity.
We take a look at several popular, though confusing, punctuation marks.
