- ‘The concept of the rest mass derives from special relativity.’
- ‘The neutrino was known from the start to be an extraordinarily light particle, perhaps massless, since its rest mass could never be detected.’
- ‘Any object with a non-zero rest mass (like a dust mote) can never reach light speed.’
- ‘Wolfgang Pauli suggested in 1930 that beta decay must involve a third particle that would be neutral, have negligible rest mass and a spin of one-half.’
We take a look at several popular, though confusing, punctuation marks.
