... We can calculate it in the TD limit The convergence factor, μ. Eventually we’ll set μ = 0. But we’ll wait until the end of the the calculations to take the limit μ → 0 , because there will be intermediate results that are singular in the limit. The singularities will cancel before we take the limit. ...

... The way to get heat out of an interstellar cloud is for the particles that make up to cloud to collide with each other. In a collision between two particles (atoms or molecules or ions), one of the colliding partners loses some kinetic energy and the other picks it up. However, the gain in energy co ...

... framework is given by (y - x + constant). Since we are looking at motions relative to equilibrium values, we can ignore the constant. Thus, substituting in Newton's law, force = mass • acceleration we have d2(y –x) K (x– xo) = M =M (y –x) dt 2 or x + K (x– xo) = y M This is the equation for a simple ...
