My father was a scientist by profession. I remember how much he talked about SMP when his branch of NRL got it. Later he learned a bit of Mathematica. Anecdote is not data, but when Wolfram claims that scientists use Wolfram Research&#x27;s products to investigate relativity, I tend to believe him. Not just because it conforms to my experience but because he is in a position to know.<p>I have found that pretty much all of what Wolfram writes is closer to this article than the popular internet opinion. I suspect that that&#x27;s because his tools scratch his intellectual curiosity...they exist so that he can start with the sort of math that starts this article and go from there...or write a book like <i>A New Kind of Science</i>.
