Why Isaac Newton’s legal guidelines nonetheless give physicists loads to consider

THERE are two sorts of theoretical physicists: those that use the proper equation for calculating distances in space-time, and those that don’t.

Clearly, I’m being a bit tongue in cheek right here, however I’m severe after I say there’s a actual bifurcation. The 2 formulations of this equation for distance – what we name the metric – are equal and when used accurately will give the identical solutions for all calculations. However every group has causes for believing that one is extra pure than the opposite. Particle physicists have a tendency to make use of one; relativists (individuals skilled usually relativity) have a tendency to make use of the opposite. I’m among the many group of particle physicists who use …
