  • It (along with Stokes’ theorem (they’re actually the same theorem in different dimensions)) helps yield Maxwell’s equations; specifically, if you want to change the flux of the electric field through a surface (right hand side), you need to change the amount of charge it contains (the source of the divergence on the left hand side). In other words, if you have the same charge contained by a surface, it will have the same flux going through it, which means you can change the surface however you wish and the math will still be the same. Physicists use this to reduce some complex problems into problems on a sphere or a box—objects with nice, easily calculable symmetries.



  • Personally, I want FDA approval to mean it is as provably safe and effective as possible. They said they wanted more evidence before approval, and I think that’s okay. Good, even.

    The way the US treats recreational drug use and self-medication is horrific, but it’s not really the domain of the FDA.

    I would rather have not-yet-FDA-approved legal-for-personal-use mdma than what we have now or an unproven drug approved by the FDA.
