Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment Interesting relationship between diffraction and Heisenberg's Uncertainty Principle?
I'm still not sure what you're asking, but the nearest I've seen to a fundamental explanation of why diffraction happens is the Huygen's construction.

comment Interesting relationship between diffraction and Heisenberg's Uncertainty Principle?
Diffraction through an aperture produces a diffraction pattern. Diffraction round an obstacle also produces a diffraction pattern. In both cases the diffraction pattern is calculated using wave optics.

comment Interesting relationship between diffraction and Heisenberg's Uncertainty Principle?
Diffraction through a slit is explained by the wave properties of particles, as is diffraction round obstacles. It's not obvious to me how you'd use the uncertainty principle to calculate a diffraction pattern.
