This was week two of my paternity leave. Babies are the weirdest. They have the shortest arms. They smile at shadows. They are so weak, unless they are grabbing hair. Eight weeks to go before I go back to teaching.
Here are ten things to share:
I love the simple logic of using 45-45-90 triangles to measure the heights of trees. You know what’s hard? Trigonometry. This forestry tool lets you avoid that. Delightfully lazy.
My daughter, aged 3, is an agent of chaos. She is Yogi Berra. (“Since it’s still old, can I use it?”) She’s also in that exciting age where numbers start meaning something. I keep meaning to blog about all the ways numbers come up just going in and out of the sixth floor of an apartment building. Anyway, she and I have been playing Memory with Tina Polka Dots and it’s so well done. A beautiful game that my kids love.
Come on, of course you want to watch a supersonic baseball canon. Scientists have fun.
I spent too much time this week trying to come up with a good “latke” pun for the Lotka-Volterra Equations. I’m still on this ecology kick. Did you know that even though theoretically when species compete it necessarily leads to extinction, it’s “rarely observed in natural ecosystems”? This is perhaps worth thinking about further.
Random: Detroit was a originally French settlement so maybe we should pronounce it “de twah.”
Scaling one-on-one tutoring up in a massive way is an idea that seems to crop up more and more these days. Here is a proposal on how it could be done. I go back and forth on whether it’s a great idea or not, but I think right now I’m at “great idea.”
Probability question: between me, my wife, and our three children, our birthdays all fall in the same half of the year. What are the chances of that?
I’m on paternity leave these days and watching movies while feeding the baby. Moneyball and The Social Network are both great movies for that “oh dear math what have you done” feeling. I’m watching The Founder now and I didn’t realize I’m on an entrepreneur kick until Reyzl pointed it out to me.
3D math from the USSR. Might make a fun math class project, though I don’t know for what.
Have a wonderful week!
