| > electron shells -> octets It's a good rule of thumb for hand waving chemistry. It's not good enough to predict protein folding, but it's good enough to understand how amino acids connect. I don't expect it to disappear. > wave function collapse I disagree because I expect a different solution to the problem. > pseudo-vectors -> bivectors I agree. We only have to convince the other 7999999998 persons :) . > relativistic mass Another good rule of thumb, but I'm not sure for whom. This days nobody has to make a DIY synchrotron at home. It can probably go away, but it will resurface from time to time like a clever trick in a YouTube video. > xyz I like covariant equations, so I agree. Anyway, at work we sometimes use some non-covariant approximations but we add a search to optimize the base to get the best one were we can apply to nasty coordinate tricks. Anyway, I needed like 10 years to understand the difference between a matrix and a linear transformation. 20yo probably only can use coordinates until they grow up. |
