i thought roger thomas was quite poor for physioology. have to admit i do tend to judge them slightly on the quality of notes :wink:

Ellar was good :smile:
There were 'revised' notes given out in Easter (or Lent - can't remember which one). His notes were seriously lacking on fatty acid metabolism. I didn't go to the last 2 lectures because they were so crap. Actually, I don't think anyone did.

What did Roger Thomas do in physiology? I don't think he lectured last year, although I could be wrong. We had some good notes from Prof. Crawford.

Cos we had the worst lecturer ever ever ever ever for metabolism (the respiration bit anyway) and they finally sacked him in time for you lot :smile:


lol have heard about that lecturer- apparently hes an alcoholic isn't he? thats what my DOS said anyway so should be better this year. as for Francois he has to be the most hopeless E&B lecturer so far, stopped going to his lectures after the first few and his notes make no sense either so supervisions are fun! Anyway the one we have now isn't so bad so its getting better.

Roger Thomas is almost as bad as the metab guy, going on my early neuro lectures this term...

edit: I'm certain he didn't lecture us on physiol last year. He did the practicals though (and I quite liked him then, so I was very disappointed when he lectured us!)

He did something about endocrinology for the medics/vets last year, but didn't really seem to know what he's talking about. And we had a few neuro lectures with him at the start of this year, though I can't remember what they were about (clearly I was awake :redface:)

On a more serious note guys, I don't think we should discuss these things too publicly, probably not 100% legally sound or something.

reason he did those endocrinology lectures was because our original lecturer disappeared off to sweden or somewhere else for a new job... he's a neuro/electrophysiology kind of guy, definitely not into hormones and stuff - i think he got stuck with the job coz he's head of physio or something.

the lectures he gave at the start of this year was much more coherent and all, if no less... relaxed :rolleyes: than before.

MNS - possibly i might have picked up the "revised" notes.

edit: anecdote about ellar - apparently he supervised my physio supervisor from last year. and when he (my physio supervisor) was still a 1st year, all the caius medics in the year went for the annual college medsoc dinner and stayed out the entire night and went for ellar's lecture the next morning in black tie and all, sat in the front row under ellar's nose, and all promptly fell asleep! (and i think ellar was still a caius medical DoS at that time!) my supervisor never told me what the DoSes did to them... :redface:

visesh, no i cant. get a dam coach.


roger thomas did muscles & animal motility, about which i am now hopelessly confused.

if any mathmo (fishpaste) or anyone who can do this type of thing is around in the next 24 hours, can someone rearrange the following integral from dydx to dxdy:

Int( Int ( 2xy^2 dy) between y=x/2 and y=1) dx) between x=0 and x=2

I evalute the above and get 4/3 - 32/60
But then i try flipping round the limits in all damn ways i can think and never get the same answer...ARGH!

you're not believe what one of the american students just said in an email! Our coach sent out details about a social which will be going for a curry. The american guy on our team emails back and says "yeah sounds cool...but what's a curry?"......WHAT THE HELL!

Sorry, double integrals haven't come up in our courses. I could common sense my way through it and see what happened but I feel that's not the kind of help you need.

is this a question from the natsci maths course? if so what number on the sheet?
You have to change the limits, it's a bit of a bastard. Draw the graph with y=x/2 over the top and it'll help you figure out which bits you're actually looking for when you integrate.

yeah is the first question on sheet isn't it, have just had to do all these qus to hand in 2day- took me hours!

anyway the answer to that one is 4/5 ....

2xy^2 dydx limits x/2 <y<1 and 0<x<2

integrating wrt y first

[(2xy^3)/3)] limits x/2< y<1

= integral 2x/3-x^4/12 dx

= [(x^2/3)-(x^5/60)] limits 0<x<2

= 4/3 - 32/60
= 80/60 - 32/60
=48/60 = 4/5

now for changing the limits its best to start off sketching the graph of
y=(1/2)x and then decide on your y limits then define the x limits in terms of y. i.e. from the graph you can see that in the triangle you're integrating over the min and max y values are 1 and 0 so use these as the limits for y. also you can see that x must be between 2y (from equation of line y=(1/2)x ) and 0 because this is the lowest x value in the triangle formed.

so you have

integral 2xy^2 dxdy limits 0<x<2y and 0<y<1

integrate wrt x first
= [(x^2)(y^2)] limits 0<x<2y
= 4y^4 integrate this wrt y
= [(4y^5)/5)] limits 0<y<1
= 4/5 as before

hope that kinda makes sense xxx
