Davey Posted May 21, 2007 Report Share Posted May 21, 2007 Well it does have real life implications... in engineering, my dads uses quite a lot of the stuff in calibration of the diseil injection pumps.... so yea its not ALL total bullAh right, well that's not so bad then, I'll get a bashing for that little rant now I can tell, lol, I still hate sociology Davey Quote Link to comment Share on other sites More sharing options...
future orange 660 Posted May 21, 2007 Report Share Posted May 21, 2007 it gets you qualificationsi read one of many articles however about university edumacated engineers lacking the pioneer and innovative attributes that made previous engineers so great; because of the now strict sylambus fundamental type thinking..in getting calculators out rather than just having a bash.pretty dull really Quote Link to comment Share on other sites More sharing options...
Simpson Posted May 21, 2007 Report Share Posted May 21, 2007 Yea my dad didnt go uni till he wad 34 though lol took the long route round Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted May 21, 2007 Report Share Posted May 21, 2007 (edited) Much respect for people who actually get this stuff, but can anyone actually explain to me what the point is of any of this, I mean what is it useful for?Nothing against people who learn it, I expect it's interesting in it's own way, but it just seems so pointless to me, like someone has just come up with it for the sake of coming up with it and sounding clever.On a similar subject, sociology is another subject that annoys me, all it's good for is becoming a sociology teacher, it doesn't apply anywhere in life or work or anything that I can tell. Maybe I'm just bitter because I'm not smart enough to get it, but seriously, who has ever used this stuff in context outside of learning it?DaveyWell, I'm doing chemical physics at uni right now, I'm only in my first year and there's not a day that does by where I don't use calculus, hell I even use it in labs.

Luke Rainbird Posted May 22, 2007 Report Share Posted May 22, 2007 Calculus is a bitch at higher level, and I've got a mahoosive chunk of it thrown into an exam todayDifferential Equations, ODEs, Partial Diffs and Higher level/complex calculus - should be fun!I for get how to do it if I don't do it recently, so I'm f**ked ;pHopefully the rest of the exam (Maths with Maple unit on Engineering Maths @ Bristol Uni) should go ok, so I can crack on with Thermodynamics crap for tomorrow, Physics after that, Electronics, Dynamics, Disc....

python_man Posted May 22, 2007 Report Share Posted May 22, 2007 well i know i failed mine didnt manage my time anddidnt finish the last 2 questions.worth 21 marks im fuked might just leave and up off to new zelandsod the maths lol Quote Link to comment Share on other sites More sharing options...
NVWOCI WVS Posted May 22, 2007 Author Report Share Posted May 22, 2007 thanks for all your help teaching me guys...but from now on im not going to rely on trials forum to learn mathss...especially the night before the exam...i failed misserably...might of done ok, not really sure until i get the grades!

Muel Posted May 22, 2007 Report Share Posted May 22, 2007 shit i got C1 and C2 tommorow.... im f**kedI got past core 1 and binned it. I didn't understand a word and got a U in my exam in january so thought its not worth it.I aint going to pass a levels anyway, they're absolutely solid.

Maybe I'm just bitter because I'm not smart enough to get it, but seriously, who has ever used this stuff in context outside of learning it?DaveyI'm bloody tired and about to go to sleep but I'll have a go at explaining how this stuff helps in real life. (well, the real work place more like), but yeah. If I remember right you like cars a bit, so take a fuel air mixture for example, if you did some tests on it, you would be able to find a trend it followed. Obviously, you could then draw a graph of this trend, that would be a curved graph.You could use all this complicated cack, by simply substituting zero as the gradient and working backwards to find out the peak of the graph (as the peak will always have a gradient of zero), and therefor the theoretically most efficient fuel air mixture that your engine should be chucking in.Personally I kinda agree with you, if I had to work out something like a fuel air mixture I'd get burning the shit and just see what worked best. But then when you get things a bit more complicated this theoretical shit kicks in, like where in a diesel where an engine uses direct fuel injection straight into the cylinder, then you have to take into account how fast the fuel will dissipate throughout the air in the cylinder to see how high it can rev with a certain fuel air mix, and which fuel air mix is going to be best at which RPM ect ect. So yeah, I'd rather work out a theoretical model of that before I started the real testing.And you really can just keep adding to the amount of variables in this kinda thing to just make the theory more and more important, like; the compression ratio, air temperature, cylinder volume, multipoint injection, fuel octane, piston shape....... the list goes on.Doubt that makes much sense as I'm knackered and only doing a national diploma at the most slack college ever, so I'm by no means great at this shite.Edit: Gotta agree with you on sociology, what the hells the point for most people?? Maybe if you worked for the government predicting public reactions to events and stuff? even then most of it would go out the window, and theres gotta be about 10 jobs in the UK doing that???

Simpson Posted May 23, 2007 Report Share Posted May 23, 2007 What about frame geometrys? must be a lot of maths involved with that? quite complex trig.... or do you jut go out and get welding? lol im sure if i made a frame i would have it all plotted mathmatically before going near tools!

Very little maths involved at all I imagine. Quote Link to comment Share on other sites More sharing options...

Given the BB height, chainstay length, wheelbase, fork length and head angle/headtube length you can work out anything else you want in like 5 mins max this way. Rather than arsing around with trig.

SQuiT-man Posted May 24, 2007 Report Share Posted May 24, 2007 Much respect for people who actually get this stuff, but can anyone actually explain to me what the point is of any of this, I mean what is it useful for?Yeh, I used to think that about a lotta mathsy stuff, but it really is useful..Im doing a masters in maths, operational research, statistics and economics at the moment and its SO useful in economics and operational research..in economics if you can make a mathematical model an economy, basically by differentiating you can maximise or minimise things, which means in real life you'd have a good estimate of how to get an optimal economyin operational research (which is basically just modelling business' problems mathematically, it just sounds flash), you can do the sameintegration is also helpful for stuff like finding the area under the graph, which might for example symbolise profits or something, which you might want to maximise too Quote Link to comment Share on other sites More sharing options...
