This one is a head-scratcher. Do skateboarders call "anti-" things goofy? What's the deal with that Dirac statistic? 162.158.154.31 23:47, 2 August 2024 (UTC)
- It's like being a 'southpaw' boxer (or at least being able to stand the opposite way, maybe in order to flip/spin the board the opposite way from what you would end up kicking it normally).
- The Dirac thing is... well, quantum physics has various uses/restrictions upon spin (and colour, etc) that isn't really physical spin (or colour) as we know it, but sort of means a kind of particle-based rotational momentum, which has to be conserved/transfered/agree in various quantum interactions (and is a quantised state, meaning that only certain spin-values can exist in a given situation).
