Things You've Always Wanted To Know

Mine: Why are DVDs so damn quiet? I've just started watching the Darjeeling Limited on a decent TV and have the volume on full. Most DVDs aren't this bad but the volume on them all is always so much lower than TV.

Do undercover coppers really never wear trainers, or is that something that people remember from an S. E. Hinton novel, and say to look streetwise?

I think it's so that there's volume in reserve for surprisingly loud sounds - explosions and the like.

it's more that tv is very loud i think

similar to the music loudness war, there's an assumption that bigger and louder is better, so when you're competing with loads of other channels you make everything sound biiiiiggg. check something like the x factor or strictly come dancing or something like that.. so loud. adverts are probably a better example, when a show goes to an ad break the volume will go up noticeably.

Also if you watch DVDs with stereo audio, depending on your decoder you are only getting 2 channels out of the 5 or 6 encoded so it can sometimes seem a bit quiet. You'll notice this especially with bad DivX rips btw. But yeah it's probably mostly to do with having a good dynamic range straight from the cinema. Be thankful!

Why can i not give up biting my nails? I've bitten them ever since i've had teeth and my fingers are fucking grim.

Because you have no will power and you are a pathetic excuse for a human being.

Have you tried sticking your fingers in your ears or up your arse regularly? I'm told ear wax and poop tastes quite bad. According to wikipedia anyway.

No fair enough.

I bite my fingernails sometimes but it's usually functional to trim them when they get a bit long and I can't locate the clipping thing. It works out fine, best when they are a bit soft after being in water I find. Technique is important.

Presumably because you have found it to be a comforting way of dealing with anxiety?

There are worse ones and there are better ones.

you're probably right. well it obviously works anyway because i don't often feel particularly anxious - maybe i should just carry on biting.

in that case, i'm doomed...

Anyway, another question, this is a more serious one (for me anyway) -

Do you have to be shit-hot at maths to be any good at physics? I ask because i'm considering going back to university, and i'd really love to do something like astrophysics, but i've forgotten pretty much everything from my maths a-level now - and i wasn't exactly great at the time either (i had a shit teacher, and got a D). And I did English Lit at uni first time around, so it's quite a step away from whatever i might call my comfort zone. I'm so, so interested in physics/maths but it's one of those things that i wish came more naturally to me - i fear i'll struggle too much on a degree...

You'd struggle at physics if were actively awful at maths, but as long as you're halfway competent you should be fine, especially if you're not planning to go into something really maths-intensive like field theory or cosmology [edit: or, gods help you, fluid mechanics]. If you got any pass at all at A-level maths with a shit teacher, especially if you took the course a few years back, then you're probably better than you think.

pretty sure that's the case. maybe not in some, more specialized theoretical areas, but in order to get there you still need to be shit-hot at "maths".

Thanks for the advice. Yeah A-levels were like seven or eight years ago for me now (let me do the maths! :confused:), i was really confident and capable with maths before then but i remember A-level being quite a jump from GCSE, and to be honest they kinda destroyed my faith in my ability to deal with numbers. But did you really mean that i should be fine especially if i'm doing something really maths-intensive? It would make more sense that i'd be fine unless i'm doing something really maths-intensive, wouldn't it? Which branches of physics are there that are perhaps not-quite-as-maths-intensive?

My brain is full of durr today - there's a "not" missing from that sentence! I've corrected it already but not before you'd quoted me. :) You mentioned astrophysics - not really my specialist area but I think there are probably lots of things you could do that wouldn't be ultra-mathsy. A lot of stuff these days involves writing computer simulations to perform calculations that aren't, in themselves, terribly difficult to understand but of course have to be iterrated over billions of times. Experimental/computational particle physics is much the same. I think unless you wanted to go into really hardcore field theory, string theory or cosmology, or perhaps certain other specialised fields that are maths-intensive (fluid dynamics, information theory...) you'll probably find that a reasonable amount of maths is acceptable as long as you can handle the progamming and data handling.

But then, this is all academic (in every sense) if you're going to do a taught BSc or MSci, right? In that case you'll have three or four years to find out what you're good at and what interests you.
