Physics Woes

I've been studying physics, because I've got an exam tomorrow at 6.30pm (weirdest time ever for an exam y/y?). I love physics, but this...

I've got a page of formulas lying next to me. Stuff like v=lambda*f, and q=n*e. Very, very basic stuff. The sort of stuff that you happily forgot in grade ten the minute they told you you were allowed to use a formulary from now on.

I'm not saying those formulas are hard to memorize. They aren't. But if you have ten or twenty of these little three-letter-combinations memorized, it's very easy to get confused. And that, dear uni, is why God gave us formularies. C'mon, I was allowed to use one in school! I thought uni was supposed to be more about understanding things and getting to the bottom of them than school.

I myself don't call making people memorize twenty three-letter-combinations 'getting to the bottom of things'.

The joke is - if you haven't understood what you're doing, you can't use a formulary. You won't know what to look up. I know this from experience. It's perfectly possible to flunk a physics exam even with a formulary.

Next thing they won't allow calculators anymore, and will give us a list of angles and their sinus values to memorize. I really wouldn't be surprised.

Urgh. I'm so utterly terrible at memorizing formulas - completely hopeless. Fortunately, I've had a string of excellent profs recently who've figured out what you need and what you don't. A calculator in Calculus? Not necessary at all - it'll often hinder more than help. In Physics? Chemistry? Well, yes. Otherwise you spend 90% of your time trying to figure out where you went wrong in your long division instead of actually solving the problem. *headdesk*

My Differential Equations prof allows us to write up a half-page formula sheet for each exam, which he collects at the end of class. And that's good! Because often it's just the really simple formulas I forget/mix up, and so I don't need to clutter it up with the more complicated ones. And anyone who doesn't know their stuff isn't gonna put the effort into making a formula sheet (and if they do put the effort in, they're going to wind up learning in spite of themselves!).

A lot of it is standardized across departments within a given university, but some professors are willing to bend the rules. ;)

Because in Physics, you can't pick convenient values that are easy to handle and will give you a nice, pretty result.

Oh, gosh. I had this absolute genius of a professor in my first year (General Relativity, I think?) who would come up with these impossibly difficult questions that twisted and turned all over and then gave you an answer of, like, four. Or ten. Or pi. It was amazing. (Crazy things like springs bouncing off each other at relativistic speeds and then passing through walls and hitting pulleys that did more crazy things.)

Of course, we just took his word for it, as none of us ever managed to solve a single problem he gave us. ;)

Nobody gives a shit whether you actually understood what they were teaching you.

I get the impression that it's like that here as well. It makes me so angry! *sigh*

I don't function well like this.

Ouch - don't blame you! I've heard such terrible things about med school instructors that're actually just bullies in disguise, and preferential treatment, and all sorts of things - dunno if those problems are as rampant over in Germany. (I know we've got lawsuits aplenty in the Medicine department.) But just forcing you to memorize by rote? It's excessive, really.

Do you have backup plans in place, just in case it doesn't work out? I'm sure you'll be able to transfer a lot of what you've learned to other programs of study - and your work ethic will surely get you through most things! :)

That professor sounds like a lot of fun :D.

It helped that he was extremely young (a full professorship in his early twenties) and extremely good-looking. ;) We were willing to forgive a lot in that class (including the two-hour final that stretched out to four before he just gave up and graded what we'd managed to finish).

Which degree are you doing?

I'm doing Atmospheric Science, with an interest in research into summer severe weather! *points to icon* The first couple of years simultaneously mirror the Honours Physics and Honours Math degrees (which means that most people freak out and switch degrees after the first term), but now that I'm in my third year we're finally getting into the actual Atmospheric Science! Definitely a good thing. And I geek out about it way too much. :D

Hope the exam goes/went well!! :-)

It's perfectly possible to flunk a physics exam even with a formulary.

Been there, done that.

But usually, the "no-formulary" exams are way easier than the other ones, no transferring or other bad physics stuff. So maybe in your case as well? Thumbs are pressed. :-)

THEY ARE ALREADY MAKING US MEMORIZE SINUS VALUES. (Okay, just the one. But still.)

Ugh :( I've not used a formulary, having studied no science *g*, but I u/st the problem. It's like the courses I once studied where we were expected to remember by rote vast tracts of black-letter law. People put tons of time into learning the words of the statutes: time that could have been much better invested in trying to understand the underlying principles. When I got to Bar School we were allowed to take a statute book into the exam, and--as with your formularly--it would have been of virtually no use to anyone who hadn't swotted for the exam. Doh...

I hope the exam was okay in the end, despite the idiocy.

(Every time I see your icon I find myself thinking 'oyster'. Then I actually look and realise it isn't. What is it, though?)

Ahaa! I'd wondered about teh caption. Nice painting! I've not come across it before. It makes a great icon. I like the way you've adjusted the colouring :)
