Black body energy as a sum of photon oscillator energies

Nov 01, 2016

This is a graph I made for contributing to Wikipedia. It shows the energy of a black body as the sum of energies from oscillators with 1 photon, 2 photons, 3 photons, etc.

Like Frogs in a Well

May 23, 2013

Simple visualizations (such as the one shown in the figure) of this curvature, typically appeal to a 2D fabric of space curved into a third dimension by the presence of a mass such as the earth. This curvature creates a three dimensional "well" into which other masses fall, thus resulting in what we perceive as gravity.

Why parabolic reflectors?

Mar 26, 2012

At school, we are taught that parallel rays incident on the mirror, after reflection, pass through the focus of the mirror, and that irrespective of the position of these parallel rays, the position of the focus does not change. But that is not quite true. It is just an approximation.

If the universe was all laminar flow, and if God was the stirrer, could he just reverse time by stirring backward?
