I thought this was really quite a nice set of papers, the clockwork universe paper was easier than the field and particles paper, but apart from the question about an electromagnetic choke, there wasn't too much to catch you out on.

I thought they were a gift, both of them.


What did you suggest for reducing the dose of radiation to the astronauts? A mate suggested that they stay at one end of the ship ... *rolls eyes*.
I suggested that they wrap some lead around the thingy, and don't have it at max power output constantly, only use it when they need it.

I said that they could either reduce the power, or encase the reactor in a denser material such as aluminium or a small amount of lead to reduce the amount of high-energy particles escaping. Though I forgot to make reference to the table of stats...

The other hard one was the electromagnetic choke question. Still to this day I have no dea what that was getting at.

I thought that both papers were a piece of piss, the only part that i struggled with was the electromagnetic choke question. No idea how to answer that one!
