@Curio In what context do you think the concept of electronegativity can be usefully applied to kaons? Or do you mean potassium?

@dmckee @Curio probably meant potassium (judging from the category of questions ze has asked here before). But that response surely shows the particle physicist in you ;)
Random physics/neuroscience question: What happens if you take a brain and put it close enough to a black hole such that time runs noticeably slower for some parts of the brain than others?
Very dumb question: If I want to find the equation of motion of a system, I could calculate kinetic energy T and potential energy V, subtract them (L=T-V) and apply the Euler-Lagrange equations. Why can't I just add T and V and take the derivative with respect to time (because energy is conserved?)
@JannikPitt Will that tell you when energy flow from kinetic to potential channels and how much and for how long? But as @PhiNotPi says, the Hamiltonian is often (but not quite always) the sum of those energies and plays a central role in Hamiltonian mechanics.
