Surprised I can't find one for this session! Anyways, time for the memory test G485 or (FP)2! How has everyone found it to learn? Ready yet?

**** this unit -- it is so, so ****.
does anyone know if we have to know the times associated with the sequence of important events in the universe from 10^-43 -> present day?

- At the start was infinitely dense / singular and all forces were unified.
- The Big Bang / expansion led to cooling (in a quark / lepton soup).
- There was more matter than anti-matter.
- Quarks combined to form hadrons.
- Atoms forms and primordial helium is produced.
- The average temperate of the universe lowers to 2.7K and it is saturated in microwave cosmic background radiation.

The timing is not important in this exam. The sequence however is imperative. Something along the lines of;
- At the start was infinitely dense / singular and all forces were unified.
- The Big Bang / expansion led to cooling (in a quark / lepton soup).
- There was more matter than anti-matter.
- Quarks combined to form hadrons.

just one more question, if you don't mind: is the right hand grip rule to be used with conventional current or electron flow?

So the thumb points in the direction of conventional current.

Whenever you see "current", think conventional current; i.e. positive to negative.

Don't suppose anyone has a link to some good revision sheets for this paper? I've been using my own and some others for the few couple of modules but I'm missing some notes on the last module for starters! Also the more revision sources the better I suppose!

Nothing particularly hard but there was absolutely no marks available for medical physics and the Universe in terms of description questions (past papers have roughly 25 marks on those descriptions of MRI, formation of stars etc. that you have to memorise).
There was a lot in the paper that meant you had to actually think about the physics, so I think low grade boundaries, once again not really hard but still a harsh paper, more so than any other one I've done.
