Today I visited four thrift shops looking for various clothing items I need. It was exhausting. Between that and some other things I needed to do today, I wasn’t up for either calc exercises or explorations.
I ended up reading more of Infinite Powers. It was fun to be doing that with a sharper mind than I often do, especially today, when the section I read covered Archimedes’s Method. I can’t adequately explain it here, but it is a way of doing geometry by imagining shapes as physical objects acting on levers. This allowed Archimedes to discover the relationships between their areas or volumes. It’s pretty wild. “Give me a lever” and I will not only move the Earth, I’ll discover the volume of the sphere, too.
love when you have “fun”
