Diffraction of a magenta laser by a cat 🐈 contour-shaped aperture, simulated using the Huygens-Fresnel principle.
The video along time follows increasing downstream distances from the aperture which show how the diffracted beam evolves from the initial cat outline towards diffractive patterns.

Antoine de Saint-Exupéry, French aviator and writer.

He was born in Lyon on 29th June 1900 and disappeared in the Mediterranean Sea on 31st July 1945 during a reconnaissance flight.

He demonstrated both courage in his air missions during the second world war and sensibility in his literary works, including its most famous one, "Le Petit Prince".

I drew him with graphite pencils and notably kept strokes for the edges, which is less realistic but better defines contours (like in the ligne claire style).

Superalloy material for aircraft ✈️ engines , analyzed by scanning electron microscopy 🔬 (with a secondary electron detector in the polar piece).

Brighter particles strengthen the microstructure through distinct and cumulative physical mechanisms.
