An abbreviation for Bohr Sommerfeld (quantization), which states that for a bound quantum state, the action of its classical equivalent is quantized. An improved version of this method is known as EBK quantization, which includes the phase jump corrections at the classical turning points (the simplest correction is the 1D case, where a factor of 1/2 appears as a result of applying continuity and differentiability near classical turning points).
Person A: I can't believe it, everything that comes out of that guy's mouth is BS.
Person B: Yeah, he's really finding it hard to accept the new quantum theory.
Bs means Bull Shit and is used when someone is talking nonsense and dont know what they are on about.
