Brownian motion is like the motion of gaseous hydrogen gas when you open a container of it to the atmosphere

:') we used it to model stocks. And by we I mean not me because I had no idea what was going on.

Applying this knowledge to something like the stock/property market sounds crazy awesome, but I'm guessing if it were that easy/definite to make money way more people would be doing it.

Oh my bad it's not like that at all. It's like super watered down. Like "if I want to sell a house and I will get only three offers (each offer will be a certain amount with a certain probability), and if you reject a past offer you can't take it back, which offer should you take?

Or if you're gambling where you can lose or win a certain amount with specific probabilities, how many times should you play the game to maximise your earnings. And shit like that.

The maths subjects within the Discrete Maths and OR specialisation look particularly interesting, and might be applicable in many areas. In particular, MAST30022 Decision Making looks pretty cool. https://handbook.unimelb.edu.au/view/2015/MAST30022

LOL. Forgive me for thinking the probability bit looks trivial.

haha oh man the stoch exam I sat yesterday was hands FUCKING down the most difficult exam I've ever sat. I don't know I single person who walked out of that exam not mortified.

Urgh yes it was the worst! And it seemed really long compared to the past exams - if I'd had an extra hour I would have had a chance to answer some of the tougher questions.

The 3rd year stochastic modelling subject leads to the Masters stochastic calculus subject, which is absolutely about the stock markets - it's the maths behind financial derivatives (the Black-Scholes equation), and how the GFC happened. Trying to decide whether to do that one next year, because I don't really care about the stock market but the maths is cool!

Anyone in Business Finance and what to compare answers to the sample exam?

Subjects like those make me wish I was better at math

Which of those level 3 subjects would most likely help me towards Elec Eng/life in general?
Can I apply any of this knowledge directly to everyday life? Would any of them open up opportunities in Financial Mathematics? (Finance is my breadth stream)

Just saw this question. If you can manage it, I'd suggest Applied Mathematical Modelling and Complex Analysis. Electronic engineering is big on complex variables and if you've done complex analysis they'll be a whole lot less scary and a whole lot more "I get how this works". The Applied Mathematical Modelling course builds on differential equations to model real-world problems like traffic flow and fluid dynamics; I haven't done it but I've heard good things from friends who took it as an elective in their MSc.

And then if you've got room left in second year and want moar maths, you could do either Discrete & OR or Prob & Stats, depending on what excites you more. OR is probably more applicable to engineering.

As for application to every day life, I'd say the best thing that a pure maths degree has given me is practice in thinking like a mathematician: breaking down complex problems into abstract concepts and being able to reason precisely about them. Totally relevant to any kind of science or engineering.

For the MC i got (in order) B B B A B A C D C D B A C

Didn't do too well on the last assignment so would love to hear what you got

Hey, I PM'd you 

[Turtle]

Well that's my science degree done. I still don't even feel mature enough to be at Uni. I still get asked "oh are you on school holidays?" if I go anywhere in pubic on a weekday 
Gosh where did those 3 years go!!!

[Hehetymen]

^^What're you gonna do next year?

[vox nihili]

Please sit one of my exams next week for me!!!

And saaaaame!!! The most embarassing thing happened to me at the start of swotvac last sem when my 15 year old neighbour asked me out thinking I was 15 too I knew I looked young but not that young?!! 

[Stick]

hehe

You beat me to it lol


And I finally got around to re-writing that subject review that I accidentally lost yesterday, this time copying my work frantically along the way.
