that's what i thought but the instructor guy that is assigned to a certain experiment said something about using natural logs etc... what does he mean?

Ix = Io.e^-μ.x

then at the bottom of the manual it says:

(Note: Using natural logirithms; ln (Ix) = ln (Io) - μ.x)

what am i supposed to do? apologies if this is basic maths or what not, as you can see i'm incapable of processing this ****.

This equation isn't linear so you won't get a straight line when you plot it. However, if you change it to ln(Ix) = ln(Io) - ux, this is just an equation for a line. Basically, plot the thickness on the x axis and the natural log of the count rate on the y axis. The slope of the graph is what you need.

How long is this week's lab for Biology?

What did all the 2nd years think of the mod fair yesterday? Everyone know what they want to do now?

Mod Fair was alright. Got a bit more information on the courses I'm interested in. Undedcided between Micro and Genetics at the moment. Chemistry and Biochem with Immunology are up there too.

Supposedly it's "short enough" from what I've gathered, no idea on specific times.

how we all fixed for this chemistry MCQ then?

I'm trying to study here now. So little time to study so much

Once I'm out nice and early, got a lot of drinking planned. ^_^

Not so well sorted for it. Coming down with a flu on top of that, so cant see it going too well.

Jammyc

Same here. Cant say I did brilliantly, but it was much better than expected.

What do we all think of the exam timetable!? I was expecting it to be much more cramped, but it doesnt seem too bad. Bio and chem seem a bit cramped but finish early!

Lucky first years...last year we had bio102 I think on a Sat in the RDS :mad:

Yeah, seen that. Second year timetable doesnt look very appealing this year either. :eek: Good luck with that..

Yeah, the first week looks especially fun :eek: Now to get back to some serious studying...

So, what exactly do we have to write up for chemistry for this week?

Just pre and post practical questions as far as I know, just like the old days.

Damn. Different demostrators must be asking for different things then. I definitly recall ours asking for a report on the day's experiment + the results sheet/questions.

So what are we keeping and what are we dropping?

Sticking with Chemistry and Biology myself (Everything bar 06 and 10)

I dont think Ill be able for next year's chem. Gonna pretty much the same Biology as you though.

Geography doesnt have the pre-requisite of JF Geog does it? Doesnt say/neigh say in the booklet!

So I went to the science office today, they say they dont know either. Is there anyone besides the guy it says in the booklet, that I should be emailing?

Thanks, tried googling it but all I got were some (brilliant) quotes. :pac:

For all the SF Science students. How long are each essay in the Junior Freshman Biology exams meant to be? Please don't say ''as long as a piece of string''.

Chris said 3-4 pages not including diagrams but alas this is subjective. Just be sure deal with the topic sufficiently.

What do all the SF people wanna do next year? 3 days to go and I'm still undecided :eek:
Anyone who's been there before fancy telling us what you picked and what the course is like? I'm so confused!!

I'm thinking, Chemistry, Micro, Immuology or Genetics. In that order.:D
