Welcome to Relativistic Quantum Reality: Virtual worlds of imaginary particles: The dreams stuff is made of: Life,the eternal ghost in the machine...
This site is dedicated to the quest for knowledge and wisdom, through science, mathematics, philosophy, invention, and technology. 
May the treasures buried herein spark the fires of imagination like the twinkling jewels of celestial light crowning the midnight sky...

Electron Diffraction Simulation:
Used to measure the value of the fundamental Planck Constant (h) of Quantum Mechanics



See also the Davisson-Germer Experiment

Bragg's Law: { 2d*Sin(θ) = (n)λ } is the condition for constructive interference,
with n=a positive integer.

By using powder crystals of a given atomic spacing
(Graphite: d100 = 2.1 [Å] and d110 = 1.21 [Å]),
And by tuning the WaveLength of the electrons to a certain length,
we can "pick" a Bragg scattering angle.
While any given powder crystal may be at any 3D orientation,
only the ones where the geometry gives the "preferred" angle(s)
will constructively interfere strongly.
