Episode notes

The action principle says that in ordinary classical mechanics, if you have some trajectory, for a ball rolling down a hill or a planet going around the sun, it has a quantity we can define called the action. The action is kinetic energy minus potential energy. So i don't think everything i just said there is true, unless i made a mistake, which is always possible. Richard graft: I'm 62 and aware of the valuable perspective that comes with those and later years. However, i've come to believe that our nation would benefit from an upper limit before 60 on the supreme court. What are your thoughts on this idea?

Welcome to the July 2022 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). I take the large number of questions asked by Patreons, whittle them down to a more manageable size — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic.

Big news this week! Mindscape is working with Bold.org to sponsor a college scholarship for students interested in studying the fundamental nature of reality. Listeners can find more details and donate here. Our immediate goal is to raise $10,000, and I will match the first $5,000, so this shouldn’t be too hard for us here. Hopefully we can raise much more! And hopefully this will help encourage someone who might not otherwise have been able to study this kind of topic.
