In my day Latex notation was so obscure that it was relatively useless as a mathematical lingua franca. Meanwhile, even Google still uses the standard programming language notation [e.g., (sqrt(-1)) ]
Hmmm, I wonder if my first edition Latex manual is now a collector’s item. I should have had Don Knuth sign it while I had the chance. (Of course, technically speaking, somebody else wrote Latex but LaTeX was a special version of Knuth’s TeX.)
Don Knuth was the only Christian I ever met who attributed his first interest in investigating the Gospel of Jesus to a “John 3:16” sign he saw on TV during a football game.
P.S. I don’t think I’ve heard anyone make mention of Latex in 30 years—but that shows how out of touch I’ve become.
