Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A law, forming the basis of quantum theory, which states that electromagnetic radiation from heated bodies is not emitted as a continuous flow but is made up of discrete units or quanta of energy, the size of which involve a fundamental physical constant (Planck's constant).
- ‘It might also be emitting more energy across the electromagnetic spectrum than Planck's law deems possible.’
- ‘This way, semi-classically light comes in little ‘bullets’ with energy given by Planck's law.’
- ‘The year 1926 saw the complete solution of the derivation of Planck's law after 26 years.’
- ‘They [showed] that if the motion of the material particles in a source of light took place according to the laws of classical mechanics, then the correct law of black-body radiation, Planck's law, could not be obtained.’
- ‘You will see that I have tried to deduce the coefficient in Planck's law independent of classical electrodynamics.’
