I studied music technology at the University of Wolverhampton. Involved studio recording, live sound recording, live sound engineering, studio engineering, sound system design and acoustics (which involved much physics and maths), music industry, marketing, film scoring and other stuff. Really enjoyable and lots of fun physics.
I then went to Birmingham City University to train to be a music teacher but there were no jobs around after leaving. So a summer job for a few quid during the summer turned into another career in commercial vehicle leasing. But all the business/marketing/website design/networking stuff I learned at uni has come in useful. So it wasn't totally wasted.
