Igor Mineyev's UnderGround

I am a mathematician. This page is meant to be a playground for some of my secret creative mathematical projects. It will be updated according to whims of creativity. So the next time life is treating you harshly, come here again for piece of mind.

Meditation. Fun tranquility. This is not your usual spirograph. This SpiroGraph draws an amazing variety of pretty-wild curves. Press the "random" button to see more. If you like, explore various settings, create, download the pictures you like, or run this game as a screensaver.

Here is another thing you can enjoy - a meditative math video. Make it full-screen and watch to the end. It is based on a particular function introduced in 1859. Can you guess the function?

... you could not direct the wind, but you could trim your sail so as to propel your vessel as you pleased, no matter which way the wind blew.

– Cora L. V. Hatch, in that same year of 1859
