MISCELLANEOUS
PHYSICS RESULTS
Special Relativity 001 (only Faraday's Law and Pythagoras needed).
Determination of Earth's Magnetic Field - V(t) of rotating 500 turn 0.36 m2 coil.
Helmholtz
Coil Analysis -
calculated magnetic field B as functions of
distances x along coil axis and away from it.
Gnu
Octave code HERE
(probably OK for Matlab as well)
Physics
of the Rainbow (a
much simplified derivation of why the rainbow is polarized is given HERE that
predicts partial polarization for a refractive index of 1.27
from which the amount of polarization from fig 17 in Physics of the Rainbow is
about 87%)
Electrostatic Deflection of Water Stream - short video
Maxwell
Wagner Effect (with an application to emulsions of
supercooled water in heptane).
Simplified Derivation of the van der Waals Force
Derivation of Relative Permittivities for Conductivity Relaxation
Online Version of Abramowitz and Stegun from NIST. Expanded and corrected from the book version. See Physics Today, Feb 2018, pp 48 - 53 for detailed description.
Derivation
of Solution to Quadratic Equations
Equation for an Ellipse - a proof that if the distances of a point from x = --a and x = +a add up to a constant then the point traces out an ellipse
Wolfram Integral Solver - Enter the algebraic expression and this will give an algebraic answer
