5:20 PM | The Physics of da Vinci and Euler

Today is the birthday of two famous physicists, though that is not how they are commonly remembered. The first is Leonardo da Vinci, who would turn 562 today. He is best remembered as an artist, but did experiments in physics, architecture, botany, anatomy, and engineering. The second is Leonhard Euler, who would turn 307 today. [...]

2:01 PM | Fractal Art

Fratals are mathematical structures emerging from recursive equations with complex numbers. A famous example for fractals is the Mandelbrot Set. This set originates from a very simple equation. The Mandelbrot Set is for a number c the set of complex numbers where this equation does not diverge.Here we collected fractals created with the Frax-App. Take a look!
