Using Great Scientist 2 discover Physics not working

In my current game on Warlords (with the last warlords patch installed) I've tried twice to get my great scientist to discover the Physics technology, however both times nothing happened. Does anyone know why this might be happening, or how to fix it?

I'm guessing its because Physics awards a great scientist to whoever discovers it, so the game might be bugging out. Any help in getting it to work would be appreciated, as I already have Academy's in all my gold cities, and a lot of my production cities as well, so I don't want to make any more.

Physics costs a lot more than one scientist bulb. In fact it costs more than two.

Hovering the cursor on the lightbulb icon will let you know what bulbing will get you. In the case of the more expensive techs you'll usually how many beakers you get for sacrificing the GS. For the cheaper, early game techs it will say (Paraphrasing) "Use the Great Person to discover Whatevertech."
I usually use my first GS to build the Science Academy in my beaker city. Subsequent ones I either use for bulbing or I settle them as super specialists. Depends on the situation in the game.

Your scientist is a bit of a dummy apparently

A dim bulb?

Oh yeah, apparantly I'd need 4 great scientists to discover physics... and Elizabeth just discovered it 2 turns after I got my current GP

Here's a screenshot btw, I think its one of my cooler empires so I'll show it off.
