This is a log of my notes over the years on my research into various things -- compiled in one place as reference, in case others also find it useful.
You will also see copy-and-pasted sections....I will get to formatting things properly eventually!!
I also take requests if you stumble on a placeholder for information you are interested in (send me a message and I will prioritize adding my notes for those).
Please note that I copiously insert images I've found on the web and I do not have any rights to them (except for a few of my photos), and unless it's art where I indicate the artist, I didn't bother citing where I pulled them from (you can see in the HTML source code where these images are taken from), but as I use images for educational illustration and this is a personal scratchpad for the academic purpose of sharing info and for just sharing things I find cool (that no one except for me looks at anyway), I hope no one will object...but let me know if you do, if by a miracle you chance on this site, and I will, of course, not use your image.
