One of the colleagues was the well-known physicist author David Griffiths, who earned his doctorate under Coleman. He championed \equiv for “defined as”, and I think that is pretty standard in physics. It appears perhaps two dozen times in the Coleman lectures.

Howdy,
I've always assumed Pascal's use of := rather than = as ``assigned to'' is because
x = x + 1
used to increment a memory location assigned the name x makes no sense as a mathematical equation but
x := x + 1
makes sense.
Good Luck,
