How could I forget this! He also recommended the name.
Wolfram had come up with some normal techie names "computron", "math-o-matic" or whatever. SJ said No those suck, use something simple like Mathematica.
I used Mathematica on a NeXT computer back in 1991. It was a beautiful machine to work on. I did a student project where I simulated the flow of the boundary of a plane region over time (like how the shape of a drop of oil in water changes over time) and it was very, very easy to write in Mathematica with cool graphics.
(Theo Gray is in there too; he built the notebook interface, was introduced by SJ to show it at some event. Theo's parents were math profs in Urbana and I studied under his dad one summer, house-sat, and I too had NeXTstep access and Mathematica since it was ubiquitous there)
