Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A fundamental and dimensionless physical constant, equal to approximately 1/137, that occurs in expressions describing the fine structure of atomic spectra.
- ‘Some of these constants, such as the fine-structure constant, are dimensionless and are not expressed in terms of units.’
- ‘Even atomic clocks can detect drifts in the fine-structure constant only over days or, at most, years.’
- ‘The researchers concluded that the fine-structure constant might well be constant, and that the variation seen in the prior work was highly unlikely.’
- ‘As already noted, the fine-structure constant controls the spectral patterns made by elements.’
- ‘This is interesting, because there are claims that the fine-structure constant, which determines the strength of the electromagnetic interaction, has actually been experimentally observed to be varying with time.’
