Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
[mass noun] A method used in quantum mechanics in which unwanted infinities are removed from the solutions of equations by redefining parameters such as the mass and charge of subatomic particles.
- ‘Using the method of renormalization which he also developed Schwinger was able to prove that a small anomalous contribution should be added to the value of the magnetic moment accepted until then.’
- ‘The solution was a trick called renormalization, worked out by Feynman, Julian Schwinger, Sin-Itiro Tomonaga and Freeman Dyson.’
- ‘‘If you remove the high-energy scale through the process of renormalization, the spectral features are very sharp,’ Phillips said.’
- ‘This phenomenon, coupled with highly nonlinear absorption and heavy pump beam attenuation, makes extraction of quantitative information from emission or excitation data very difficult without appropriate renormalization.’
