Band 6 for physics. What a relief! I just wasn't quite sure. I suppose had better look up the science transition workshop-- enrolment is tommorow. Thanks for the replies :).

Was 99.10 this year, a typical rise over last year's 98.85 or something.

Sounds great. Is entrance really all that selective though? I'll be accepting my offer for a place in the Bachelor of Science (advanced mathematics) program tomorrow, and have received indication that I'm likely to be accepted into the faculty of science's TSP. Although the School of Mathematics...

What was your experience of the SSP in maths by the way?

I read some time ago that it's because T = 2pi(l/g)^1/2 is only an approximate solution to the differential equations governing a pendulum's motion (it only gives good results for small angles).

Although we haven’t covered this yet in class in detail, my current understanding is that superconductivity arises from the "binding energy" inherent in each Cooper pair. Since the pairs possess a minimum threshold energy to be disturbed or separated, the thermal "knocks" from the lattice around...

i just got my half-yrly report , i got maths extension 1 1/17(ranking) ban6 maths extension 2 1/10 ban6 esl 2/17 ban 4 physics 5/10 ban4 chinese background speaker 2/14 ban5 our school is about ranking 100 so what i could get in hsc？

Aha, my mistake. The diagram I drew was rather misleading. Perhaps this is the more general result -- put forward with due tentativeness after the last mistake (i'd scan it up if i could). angle MPN = 360 - (90 + 90 +2tan-1(b/a)) let tan-1(b/a) = @ = 180 - 2@ Area = 1/2absin(c) =...

Has there been a post for part iii yet? Might've missed it. Anyway, Area of triangle PMN = 1/2*PN*PM = a^2b^2/2(b^2 + a^2)... Perhaps that was just trivial enough to go without saying, heh :confused:. Praise be to whoever's idea this thread was by the way.

Although I'm no expert on this by any means, I should think that an object's wavelength would be effected by relative velocity in the same way as momentum, kinetic energy and the all the rest would. Of course, if the object was travelling at significant fractions of c one would have to apply the...

Well, it applies to attractions between any object and the earth -- the mass need not be near the surface. Love nitpicking. (Referring to GM/r^2, of course F=mg has the value 'g' determined for the radius of the earth) <- Edit The formula GM/r^2 refers to the gravitational field (a vector...

In all fairness, I have seen the full series more than once, and enjoyed it very much each time- but no matter how many times I propose to watch it over and over I don't think I could come any closer to being able to say whether or not the entirety of string theory is "right" or not. Perhaps any...

EDIT: Subscripts were not working, changed algebraic symbols. Ok, I had a little play with this. This was the result: m = mass of the earth o = mass of the object a = acceleration towards the earth v = velocity of the object (perpendicular to a) G = gravitational constant r =...

Re: Science Olympiads I recently enrolled for the physics NQE. I don't expect much to come of it, but if nothing else it should certainly help out for HSC physics. I think if anyone can do reasonably well (40% or thereabouts, possibly less) they should be pretty set for HSC science. It also...

Thought I might've come off as a bit bitter. I was just surprised that people didn't notice that the style of writing in that post was considerably different from what kurt had exhibited elsewhere (or in the least suspiciously advanced), and that they went from there straight into calling him...

I couldn't help but laugh at that one. You're almost quotable kurt =p

Eddy currents induced in the superconductor by the permanent magnet (or whatever you're using, but a permanent magnet is rather common) produce a magnetic field that perfectly counters that of the magnet itself- hence the levitation. In light of this, a superconductor is a perfect diamagnet.

I think that the point of this thread has been forgone somewhat. echelon64 asked "why is [the speed of] light constant"?. It's a good question really, and a somewhat simplified answer can be derived from the discovery that mass and energy are essentially equivalent (by E=mc^2 - just about...

Yeah, I have a bit of an interest in particle physics.

The standard model has its problems, but thus far at least its predictive and explanatory power has FAR outweighed that of string theory- so on that basis alone I would go with the SM. However, I tend to have a gripe against anything that can't be readily proven- which suggests that I would...
