Most physics teachers can't teach and like most of my physics professors they never get their math right....
I had a prof forget to put a lorenz correction in Quatum mech at the beginning of class he gets to the end and I tell him the speed of light in his equation his equation is the speed of throwing a pie on the wall and he....plots numbers in and sees I'm right 10 miles an hour......after everyone left the class I came up and told him what he did wrong.....
at that point I realized that most physicists really aren't as good as systems architect/designers. Because understanding relationships and the math associated is what they need to do everyday in new ways.
Now I'm not talking about every system designer arch and every physist...
