The relative sizes of the stars and planets

My colleague sent me this link which shows the relative sizes of the planets in our solar system and some of the brightest stars in the sky. Not only does it make the Earth look small, it makes our sun look small. Pretty amazing! Just for fun I decided to create an interactive GeoGebra applet…

Playing the probabilities in Settlers of Catan

One of my favorite board games is Settlers of Catan. I encourage all of you to check it out. It is a great game because it is a combination of luck and strategy and it is different each time you play. I’ve been on a big Settlers kick lately, because I’ve downloaded a version for…

New applets page

Over the last few years I’ve made quite a few web applets. But they have been scattered all over the place. As a good end-of-semester project I decided to consolidate all of them and create an¬†applets page. Enjoy.

Geogebra applet for families of discrete dynamical systems

As I mentioned recently, I taught the last two weeks of my colleague’s differential equations course. The topic was discrete dynamical systems. I posted links to a few Geogebra applets that I made, namely,¬†applets for illustrating one-dimensional dynamical systems and an applet to generate cobweb plots for the logistic map. This is my third and…
