These pdf files are the most up-to-date version of the matter of this site. A pdf file of the complete site is quite large, so I have broken it up into four parts:
Other miscellaneous stuff, overview, some of it rather math-heavy:
And on quite another subject (why not?)
Especially, I love various explanations that science offers of things. I realized this the day I first read about the electron transport chain (or ETC), or oxidative phosphorylation. That’s a mouthful, but the basic principals are simple as 2+2=4.
Should “universe” be singular or plural? Maybe there is a multiverse and our universe is just one of its constituent parts. That subject is at the bleeding edge of cosmological physics and can’t be answered right now — may never be — but some prominent cosmologists think it might be true.

Sadly, funding for the telescope, which should nevertheless remain in orbit for another 65 years, was cut off, as NASA considered other projects to be more important. In other words, for lack of money. It is hoped that CalTech will be able to find funds to continue using the telescope.
