Old antique physicist (BS, MS in the early 1960's) reporting for duty.
My career actually consisted of engineering physics, designing stuff to do what I wanted it to do, with the knowledge of physics that I had available. Acoustics, radiography, and eddy currents were my specialties. Nondestructive evaluation was the name of the game.
A friend of mine and I followed the magnetic monopole work for several years, but it never worked out.
The experiment I did for my undergraduate finals was an optics experiment, but it was relatively simple, as in it took me longer to write it up than to do the experiment.
My father was not impressed with my physics studies, since he figured that when he was taking the courses, electricity ran the other way (in other words, they thought that positive charges moved rather than negative charges).
Still, I have had a lot of fun with physics, including the physics jokes that appear in QC.
