I stumbled upon Wikipedia back when the project was in its infancy. In 2004, I decided to join the project as a volunteer to submit animations and illustrations for math and physics articles, all released in the public domain.
I firmly believe math and physics are beautiful topics that deserve to be cherished and understood by all, and it’s a life project of mine to do what I can towards that goal. I developed my own software to generate the graphics and animations that I wanted, since I needed full artistic control and the existing tools were too limited.
In these past 14 years in the project, I’ve created many now-iconic animations and illustrations and I'm one of the featured illustrators in the project. I’ve come to be very respected and cherished for this volunteer work, and many people have sent me emails, messages and even money donations over the years, thanking me for my work. I was even interviewed for The Daily Dot.
A few of the Featured Pictures are displayed below. See the full gallery on Wikipedia.
A visual and intuitive explanation of the radian unit of angle measurement, and its relation to the mathematical constant π.
The Villarceau circles on a torus, a rather obscure property of the torus with surprisingly deep mathematical and physical connections.
A classic example in topology, the coffee cup and donut are topologically the same.
An intuitive visualization for line integrals of a scalar field, showing how they are connected to the familiar 1D function integral. A vector field version also exists.
I intend to expand upon these into a larger multimedia educational project in the future.
