Simple math humor

on November 24, 2025 in Creativity, Education, Humor, Stories

Saturday I posted about a joke I did in a college math class. That math class did witness a great joke, but not by me, and it may only make sense to people who have done advanced math. The professor was going to prove that a certain group, which is a precise mathematical concept, had a certain property. The group is the set of symmetries of an icosahedron. The property[…] Keep reading →

Library strollers and nannies. Why are nannies almost only female? Where is the call for equal employment for male nannies?

on November 15, 2025 in Education, Nonjudgment

Longtime readers may know that when I lived for a year in Paris in 1990-91, I was an au pair. I lived with a family and took care of their young daughter. It was a wonderful opportunity for all. I don’t know if you can tell from the pictures below, but my neighborhood library is a popular place for young kids in strollers, taken there by adults. As far as[…] Keep reading →

Conservative, libertarian, and Christian posts in my blog and podcast episodes

on November 6, 2025 in Education, Freedom, Nonjudgment

Most people who call themselves environmentalists are on the political left. I talk to a lot of them. I also talk to people on the right and in other directions. I learn from all of them. I decided to compile them for reference. Some blog posts (I’m sure I missed a few): Podcast episodes:

My fifth annual cooking workshop at Drew Gardens: pictures and video

on October 27, 2025 in Doof, Education, Nature

I love Drew Gardens’ space and community. Every year I lead a workshop on cooking, though less now about low-cost, low-waste cooking. Now I focus on helping them create a food coop there. The city has some programs I consider “push,” where they try to supply fresh, local produce to the community. Having grown up with parents who, because they struggled to make ends meet, started a family food buying[…] Keep reading →

The joy of learning from people I diametrically disagree with (I recommend the practice)

on October 22, 2025 in Education, Habits, Tips

I’ve written before about a practice I’ve come to see as a part of maturation: reading and studying people I disagree with—the more opposition, the more I value the learning. I mean more than just learning their views. I mean empathizing with them, learning the sources of their views, and reaching a place where what they say makes sense. Reading, learning, and understanding don’t mean agreeing or supporting. On the[…] Keep reading →

Abolitionists didn’t free slaves by teaching children that slavery was wrong. Yes, they taught children, but they freed slaves by freeing slaves.

on October 18, 2025 in Education, Freedom, Leadership

I’ve written that, yes, we should teach children about living sustainably, but teaching children doesn’t solve the problems we’re teaching them about. On the contrary, if we teach them to do what we aren’t doing ourselves, they learn from our behavior, not our words. We will lead them to see polluting and depleting like cursing or drinking, something kids have to wait until they grow up to do but that[…] Keep reading →

“Do the reps, you get the results. Don’t do the reps, you don’t get the results.”

on September 17, 2025 in Education, Fitness, Habits, HandsOnPracticalExperience, Leadership

I’ve been saying these words lately. Do the reps, you get the results. Don’t do the reps, you don’t get the results. I’ve said them to myself, my teammates, and my coaching clients. As regular readers know from my sidchas and standard procedures, I live them. When I search the web for them as a quote, I don’t find them, so maybe I created the quote. They ring true, particularly[…] Keep reading →

Don’t only “teach children sustainability”. Here’s why and what to do instead.

on September 2, 2025 in Education

When people become corrupted—that is, when they act against their values—they come up with what I call cockamamie schemes. They create elaborate plans that a moment’s reflection would show are impossible. Before the Civil War, for example, people created schemes to colonize Liberia, Nova Scotia, and other places with freed slaves as a way to solve the problem of slavery. People then also came up with the “Diffusion Argument,” which[…] Keep reading →
