How come all physicists do not go on to be train drivers?
Apparently, they are asked to visualise what happens to trains when they travel relative speeds cf the speed of light.
But also in an average exam they get questions like;
If Tommy was on a Train to New York travelling at 150 miles per hour left DC at 10:00AM and in the other direction Julie was travelling on a south bound train from Boston at 250 miles per hour, with her train leaving at 12.00PM. If the barometric pressure is 101 kPa and the temperature is 51 F, what app will Tommy be using on his smartphone?
So how come Physicists are not conditioned to end up in a train related vocation?
