## Visualizing Pascal’s triangle remainders

In a comment on my previous post, Juan Valera mentioned something about visualizing multiples of prime numbers in Pascal’s Triangle: In college, there was a poster with different Pascal Triangles, each of them highlighting the multiples of different prime numbers. … Continue reading

## Dimensions: go watch! now!

I finally got around to watching the Dimensions videos, which I mentioned once before. They are super cool and will be sure to blow your mind! They start by explaining some simple tools (stereographic projection) and intuition (with references to … Continue reading

## Book review: Viewpoints: Mathematical Perspective and Fractal Geometry in Art

This book is certainly quite different from the sort I usually read and review—but I am always interested in new and creative ways to teach mathematics! This is quite a fun book. It’s all about visual art and some of … Continue reading

## Fractals without a computer

What happens when you hook up three projectors to a single video camera, and then point the camera at the projected images? RIDICULOUSLY AWESOME THINGS, that’s what!

## Battlestations!

The world’s LARGEST FRACTAL DORITO!

## Pentaflakes

Just a link today: Mike Croucher over at Walking Randomly has some gorgeous pictures of fractal constructions called “pentaflakes”, made by recursively gluing pentagons together in various ways. He’s also made a Mathematica demonstration for playing around with various sorts … Continue reading
