RIP Professor Nemeth

"For example, when you say “x to the n power,” the phrase “to the” means “begin a superscript,” and the word “power” means “return to the baseline.” So in my Braille code I created symbols that mean “begin superscript” and “return to the baseline.” My personal code for Braille mathematics began to evolve. I used it for my work in calculus and statistics."

Abraham Nemeth, the creator of a Braille system for math and science, has passed away at the age of 94.
