Calculating pressure needed in a misting system.
Take a look at the Bernoulli equation. The Bernoulli principle states that the sum of static and dynamic pressure is constant for an incompressible non viscid fluid. Static pressure is about the
pressure that the fluid would exhibit at rest.

I know that E(X^2) is the definite integral of x^2 * f(x).
But what if f(x) = (4/3)(x^-2) ? The answer in the texbook says it is [4x/3].

I've been trying to read Gross' paper on Heegner points on $X_0(N)$ and I am stuck on a few details. The definition he is working with is that a heegner points is a pair $y=(E,E')$, where $E$ and
