Come on, how many artists do you know who will have enough of a
background in mathematics and physics to have a hope of doing that?

You might as well tell a bunch of engineering students that they need to
consider the interaction between the æsthetics of composition and
socio-political emotive responses.

The overlap is non-zero, some do have a hope, but it's not OK to make it
into a barrier.

Here we agree :-)
