He’s best known for coining the term “fractal,” so it might be appropriate to remember him by looking at some pictures of the Mandelbrot set. He discovered this hauntingly beautiful fractal shape while exploring the mathematics of imaginary numbers. His discovery inspired generations of scientists and mathematicians, some of whom have recently found a 3D version that they call a Mandelbulb. (more…)

I’ve found stereograms entrancing ever since I first managed to “see” one. If you can’t see them, try viewing these images on one of those shiny new LCD monitors and focus on your own reflection. Be sure the monitor is perfectly level, and your head is perfectly vertical. Then use your peripheral vision to search the image for a hint of 3D structure but keep your face in focus. With any luck the image should simply *pop* into view. (Unless your eyes point in slightly different directions… right?).

These images fascinate me because they’re essentially tricking my binocular vision into hallucinating objects when I look “through” a pattern of (almost) random noise. I used to make my own stereograms using (more…)
