I am a graduate student studying astrophysics at Princeton. I received my bachelor's in physics and mathematics from Caltech (2011).

@DavidHammen Interesting too that Lineweaver cites Dave Stevenson's notes, which predict numbers closer to what you are saying.

comment Physics First: Where is Science Education Today?
@BenCrowell By "at the calculus level" I think I mean the same as you -- not necessarily knowing calculus, but comfortable enough with solving equations and having a feel for functions' behaviors that one could teach them calculus at that point. In my mind calc isn't a particularly high bar (no reason it needs to come after trig for example).

comment Physics First: Where is Science Education Today?
My HS teachers all agreed physics -> chem -> bio made sense pedagogically, but that this was in reverse order of the amount of math required. You can teach bio without anything, you need algebra for chem, and you really should be at the calculus level for physics. So unless you also forced middle schoolers to be proficient at pre-calc, it just couldn't happen.

comment What's the meaning when Kerr-Newman metric's mass is zero?
Are you trying to force charge and/or spin to be nonzero even as the mass vanishes? Because you're really only supposed to have $a^2 + Q^2 < M^2$.
