Favorite Lecture

Today I gave one of my favorite lectures. It’s not because it’s about the field of my expertise. Quite the opposite, really.

I love this lecture because I get to draw. And I like to draw, as you might know already.

The topic is ocean circulation patterns. I have to draw the entire geography of the Earth. Twice. Once to illustrate surface currents,

…and once to illustrate the deeper currents.

Here are my lecture notes from last year. I was particularly proud of these:

This year, the drawings aren’t so pretty, but they still convey the same material:

Same material, different year.

This year, I had some editorial help with the map. It turns out I have a very multinational crowd. I tried to make sure everyone’s home was accounted for.

I had to laugh, because if you look closely, you’ll notice that I drew a kangaroo on Australia both years. Last year’s drawing was quite kangaroo-like:

Last year's kangaroo. Low resolution, sorry. But you get the idea.

This year’s? Well, it wound up looking like a velociraptor, so I went with that…

This year's veloci-roo. Oops.

I wonder what next year’s notes are going to look like? Will I be able to draw a kangaroo? If you take my class, maybe you’ll find out!

  1. Wow. I didn’t know anyone still used real chalkboards!

    I never could get the hang of writing/drawing on them. The texture of chalk and chalkdust gives me the heebie-jeebies.
