One Mathematical Cat, Please! An Interactive Slide Show

Personal computers (PCs) were starting to appear in the early 1980s,
just as I was beginning my graduate work at the University of Oklahoma.

(By the way, my undergraduate degree is in Civil Engineering.
I worked for three months as an Aerospace Engineer at Tinker Air Force Base.
Then, I came to my senses and went back to school.
I started my graduate work in engineering, but quickly changed to mathematics,
and have lived happily ever after.)

I fiddled around with some not-very-satisfying computer-based mathematical typesetting systems for a few years.
(Like the T³ Technical Word Processor. I'll be impressed if anyone has heard of it.)

But,
in about the mid-1980s,
TeX (it rhymes with the word blechhhhh)
came along and changed my life.
