Learning the rules and then playing the game. Also, tying your shoes, technology and the Canterbury tales, why women apologize more than men, Maggie's link to a video of the Shaker Heights High Marching Band, and Sevil on Embracing the Devil within.

How we know that the sum of the angles in a triangle add up to 180º.

Continuing to go high when they go low.

So many things in our lives happen in threes - or at least that's the way we group them. Also, an airplane phone hack, Uno's reverse card, yoga meditation alarms neighbors, fake Canadian tourism ads, Maggie's link to a topologist's map of the US, and Karin Prater's SwiftData series.

Learning to tell someone a story they already know.

During the height of COVID we stopped shaking hands - now I notice I hug more than before. Also, Stephen Fry's voice used without his permission, Futility Closet is back, R&R HoF drops Jann Wenner, a library trolley fantasy, Maggie's link to Michelle Khare working the garbage truck, and John McCall's talk on the advantages of Swift.

How do we know when a line is straight? What about lines on the surface of a sphere?

Do the things while we still can (or may). Also, leaving the toilet seat down, an art piece seized from a museum, are any museums ethical, the cost of owning a $500 car, the origins of Keep Two Thoughts, Maggie's link to "I bought a roundabout", and setting your legacy contacts for Apple devices.

We see why there are no parallel lines on a sphere and also note that the angles in a triangle add up to more than 180º

I'll be delivering three workshops over four days in London in November. Join me!
