I’m postponing the next meeting so I can focus on the website.
I don’t know if I’ll be ready the following Sunday or not, so I’ll post another update when I’m ready to resume.
In the meantime, enjoy your Thanksgiving! -

During Sunday’s talk on Nov 3, I’ll ask participants to use my website again. Please plan to attend in such a way that you can both participate in the video call and interact with my site. For example, you might have a window for each, or you might have a second device for my website.
Thanks.

To document some of the feedback regarding the site:
- The site lacks a certificate.
- The handle for adjusting panel spacing is easy to miss.
- The monotonic restriction for lemmas 2 and 3 can be mistaken as computer sluggishness.
In addition, I know lemma 4 needs to be redone.
I welcome further feedback.

I will begin examining the contents of Newton’s Principia, starting with Lemma 1.
In modern terms, Lemma 1 is about limits and convergence. -

I think it might be a good idea to always post the link (we had to scrounge around for it last time).

After Stefan’s question about Kepler being excommunicated, I went back to re-read this section from my book on Kepler. I reproduced several pages here for anyone interested. [from Voelkel’s Johannes Kepler and the New Astronomy]
When Kepler arrived in Linz in May 1612, he was emotionally exhausted. The splendid intellectual society in the…[Read more]
