Should be a good talk

Sergiy Migdalskiy, a programmer at Valve, will be giving a talk at GDC this week at the start of the THIRD month on the THIRD day at 3 PM. According to Sergiy's LinkedIn he has worked on games such as Counter-Strike: Global Offensive, Portal 2, Left for Dead, and its sequel.

I personally won't be there, but if you're at GDC you might consider going. Seems like Sergiy might give a good talk about physics and you could learn a thing or two or THREE.
