What exactly is Hooke's law defined for?

I used to think that Hooke's law was a relationship between how much a bar under uniaxial loading deformed and the internal force (per unit area) that developed within that...

If a massive sphere spins faster and faster, will a black hole appear?

If we make an object moving faster and faster in 1 direction no black hole will not be produced. We can always find a frame in which the mass is...

The boundary condition for delta function

Beginning with the Schrödinger equation for $N$ particles in one dimension interacting via a $delta$-function potential $$left(-sum_{i=1}^{N}frac{partial^2}{partial x_i^2}+2csum_{<i,j>}delta(x_i-x_j)right)psi=Epsi$$ Why the boundary condition equivalent to the $delta$...

Is damping rate of a pendulum dependent on the number density of the gas?

Robert Boyle in 1660 conducted experiments where he pumped air out of a vessel with a swinging pendulum. He discovered that the damping rate of the pendulum is independent of...
