Coffee-Powered Stargate
Let me open the Stargate of Diffraction for you, once again! This is as close as I ever got to a plain scientific visualization: No 3D effects, just the intensity of diffracted radiation as a function of position in space. If you use a sun catcher – a film with a diffraction grating – the…

Celebration of Dispersion
Light is economic. It takes the minimal path. It follows the Principle of Least Time! When light is reflected, the angles of incidence of original ray and reflected ray are the same. This might seem natural. But you can derive it from the Principle of Least Time – also called Fermat’s Principle. If we want…

First Encounter
You try to find an object to draw. Ideally, it should already sit on your desk! Ideally, it should be translucent and sparkling! You try to make it look interesting… Adding little rainbows, perhaps? No sun today, so: Fetch the replacement sun! The spectrum of a flashlight is duller than that of the sun. The…

Stargate of Diffraction – Brought to Life!
When you look at a streetlamp through a finely woven curtain diffraction patterns are registered at the retina of your eye. When you look at the reflection of your reading light in your smartphone’s screen, diffraction happens. Instead of a sharp image, you see a kaleidoscopic multitude of rainbow-colored overlapping, blurry images. Each point of…

Drawing the Light?
I’ve called my type of art Art Inspired by Physics, sometimes adding Engineering, Math, and Tech. But maybe I should be more specific? I think, I am drawing the light! Sometimes, this is obvious: When I pick random things, I am choosing glass first, translucent plastic second, then imagine opaque things as being transparent: Light…
