Not exact matches

He grew up bodysurfing in South Africa, and he enjoyed using random flat objects, like fast - food trays, as hand planes to help him gain more control over a wave as he glided across it.

Nolan and cinematographer Hoyte van Hoytema («Interstellar») shot the film using 65 mm and IMAX cameras, and while the big scenes of spectacle are unquestionably sweeping and impressive, it's the smaller moments that stayed with me more, whether it's those cascading leaflets in the opening scene, the terrifying majesty of a fighter plane gliding with its engines off, or a harrowing sequence involving a downed plane that will doubtless be used by English teachers to illustrate what poet Stevie Smith meant when she wrote «Not Waving but Drowning.»

what exactly is it that determines the probability of an energy transition such as an electron emitting or absorbing a photon (besides densities and occupancies of states and incident photons, etc.)-- and how does refractive index affect this (it has to because the Planck function is proportional to n ^ 2 — has to be in order to satisfy 2nd law of thermo...)-- and does it make sense to use an k, E diagram when electrons are not actually propagating as plane waves — I mean, what is the wavevector when the waveform is not a plane wave; is k a function of space in atomic orbitals?
