    Maglev train

    Of course maglev trains use superconductors! Main problem is cost, as laying out many miles of solenoid tracks as well as creating an entirely new infrastructure would cost a lot of money. Currently, a maglev system is currently being used in Shanghai, but other countries such as Japan are...

    2015ers Chit-Chat Thread

    If the option was still available, would anyone take the course? It doesn't count for the minimum 10 units required for the HSC, so i'm assuming that all participants do the course out of sheer interest or perhaps they are naturally good at those subjects

    BCS Cooper Pairs

    This is what you should talk about. In reality, the electrons move in opposite directions to obey the law of conservation of momentum, but you must talk about them moving in the same direction in HSC physics. Also, magnetic levitation can be caused by both eddy currents and cooper pairs - you...

    Does God exist?

    'I believe in Spinoza's God, who reveals Himself in the lawful harmony of the world, not in a God who concerns Himself with the fate and the doings of mankind...' - Albert Einstein https://www.youtube.com/watch?v=pVEeXjPiw54&feature=youtu.be&t=1m22s

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive From what you're saying, it seems like you're implying that the there is zero electrical resistance due to the elasticity of the lattice? But rather, what you should relate this to is the formation of cooper pairs, and it's due to the idea that each electron...

    Will i get flagged

    One of the main points stressed by most teachers is that your short story should be based on a genuine moment or situation because you're likely to be much more descriptive, and it could possibly resonate with a wider audience

    Maximum points for EAS

    Unsw has a "hsc plus" scheme that awards up to 5 bonus points for achieving a band 4, 5 or 6 for the subjects that are somewhat relevant to the courses that you apply for (I'm sure you can find more information online) They also offer extra points for people from disadvantaged backgrounds...

    Related Texts

    For mod c, you're either doing "representing people and landscapes/politics" and you will basically have to find at most 2 related texts that supplement or argue against the main ideas of your prescribed text in relation to the way people and landscapes/politics are represented Mod b won't...

    Double Angle Identities

    Well let's see 1+cos(180+2x) = 1+cos180cos2x-sin180sin2x = 1-cos2x = 1-(1-2sin^2x) = 2sin^2x The reason why you used this variant was to remove the 1

    Is this use of apostrophes correct or not?

    I see it used all the time... "Mathew's the best" "Bob's lifting the weights" Is this a correct use of apostrophes? I'm pretty sure that for people, apostrophes are used as possessives only

    Does God exist?

    ^ Yes, it is probable that a man named "Jesus" existed at that time and claimed that he was the son of God, HOWEVER This is what Jesus supposedly did: - Turn water into wine - Feed thousands of men with 5 loaves of bread and 2 fish - Resurrect from the dead So we must ask ourselves... is he legit?
