Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A region in a field of force, in particular the region in which an atomic nucleus is situated, in which the potential is significantly lower than at points immediately outside it, so that a particle in it is likely to remain there unless it gains a relatively large amount of energy.
- ‘Engineers can control the colour of the light emitted by the laser simply by adjusting the energy levels within the central sheet, which acts as a potential well.’
- ‘Then, by applying an electric field perpendicular to these layers, you create a potential well which can confine electrons along this perpendicular direction.’
- ‘This lattice can trap the neutral atoms in potential wells because the electric fields of the lasers induce a dipole moment in the atom.’
- ‘The defects produce a potential well which holds the electrons in them.’
- ‘Each particle thus diffuses in a potential well and its movement is simulated using a Brownian dynamics algorithm.’
We take a look at several popular, though confusing, punctuation marks.
