We're using generating functions, and recurrence relations of homogeneous and non-homogeneous types The mark allocation is 2, 3, 3 and 2 The Attempt at a Solution I think I've done the first part correctly. The closed form is in terms of z, right? I get: F(z) = z / (1 - z - z2)...

Thanks, Inside the cylinders we keep them at a higher pressure when compared to that graph

I'm trying to get my head around a concept. We use Industrial Gas cylinders filled with SF6 gas - the gas cylinder is 70-80% liquid and the rest is in a gaseous state. If this is kept at a pressure of approx 40Bar and is passed through a regulator that allows the gas to be filled into a...

should this be in the string theory sub section?

interesting video. The more research I try to do behind this - the more confused I get. Apparently he uses some form of diamagnetic levitation which some say was faked for the documentary. I'm skeptical but I have to admit the video is damn interesting.

I'm a recent EE grad and a I have a month to spare before work. As lazy as this sounds, I'm not too keen on working an odd job, or even tutoring until work begins. Spent the last few years doing that along with college. I was wondering if I should attempt to go through Griffiths Introduction...

thanks for the tips - will make an effort this weekend. In the meantime - this will sound weird, but I'm dusting off Introduction to EM by Griffiths - always wanted to finish that book.
