I remember last year's talented students day at UNSW. So damn hard to go home because the buses were all full of other students. Plus we were wondering on which bus to take home..

For me, somewhere in week 3, so I guess it's in about 14 days.. any plans to share the paper? :p

What if what you think is real is not real? What if Einstein was not there, and all these theories of relativities are not real? What if, it's just a rule established by The Matrix to make sure no-one goes at a speed too fast inside the "matrix world" ?

Why don't you just look at the past paper answers? Not just looking, but also trying to do it before hand. The part where you try to lock yourself in a strict exam conditions should be left to the last :) I was in the same situation as you last year, and how i survived was an excel HSC...

cloud chamber is in the conquering chemistry book. Whether it is a wilson cloud chamber is another question, but ill just help you by typing a bit : This is an instrument which contains a supersaturated vapour of water or alcohol. When radiation passes through it, it ionises some of the air...

very g question *claps* :D

btw, light slowing down on different mediums are prelim stuff, and I've never seen them on the HSC course. So relax, and just concentrate on relativity :)

isn't it because light bounces off the atom lattices of glass, or crystal hence slowing it down, etc?

too late for choosing now, i just crammed the whole medical physics syllabus to my head :) because medical physics is shorter does it get nerfed in marking or whatsoever? the successone specimen papers makes it look pretty easy, im just curious.. What did the top physics students do as...

talk about genders, what gender are yous? the usage of female avatars and female names (e.g spice girl) can lead some people to think you're a girl, but in many cases many are not. i'm curious on yous.. by the way im a boy it's a boy! it's a boy!

I'm also quite curious whether diffraction gets that in-depth (to grating and that n,\ = d sin@ equation. I don't think the specimen paper from successOne covered such detailed stuff, but im still curious..

last year, top half ranks are all taken by girls. This year, the top two are boys, and there's only 4 girls in my 3U maths class of 20. Welcome to the circle of in-class gender imbalance :)

dickhead ridwan.. i never expected i'd see you here.. you noob

looking at F = GMm/r^2, you can just say that F gets bigger when M gets bigger, F gets bigger when m gets bigger, F gets smaller when r gets bigger, and F gets bigger when G gets bigger.. I think you already know enough :) something related to gravity...

for the syllabus point, is it something to do with transistors, or current rectifiers? i think because of the hole and electron stuff of semi conductors, the {edit:charge carrier} would be carried to one side and vice versa with the holes. But because of the opposing charges, a new electric...

oh.. i get it now been like 7 months of relativity wondering, and now i understand the whole picture after a short answer.. this is why the education system sucks.. thanks a lot anyways

Consider this exceprt from excel book: "Consider a spacecraft moving at speed of c/2 (half speed of light), towards another planet. An astronaut in the spacecraft now flashes a light beam in the direction of the motion of the spacecraft. What is the speed of the light relative to the planet...

they made our lives harder.. considerably.

discovery of photoelectric effect was just accidental by hertz, and then after Max Playnke said his photon thingy, einstein got the noble price for it in 1905 right? I think the photon theory just fits very nicely with the photoelectric effect, and that's what's important about it. Right?

too bad.. wanted to learn how to make atomic bombs in quanta to quarks.. stick with medical physics i guess, its' not that bad is it?
