This is ridiculous

Britney Spear's teaches physics at this site.
Physics should be taught by people that actually know physics!
Will students suddenly want to learn semiconductor physics if someone pastes a few pics of a pop star in learning material? I doubt.

Nevertheless, crappy use of Photoshop does not help. Nor does the fact that a male star pic is not present. To make it fair I just decided to add one and i picked Mc Dreamy :

I am sure that Ch.E.Guye will not be missed as he was the most obscure of the scientists present at the Solvay conference.
