yeh i've read that thing about making some wavelengths of light travel faster than the rest, but i think thats just playing tricks... besides, its only light - so an actual object with mass wouldnt be able to do this. but what i was talking about is things that i have heard where it is possible...

i'm wondering.... ive heard people talk about how it's impossible to accelerate to the speed of light, and yet in theory if you could jump to a speed faster than that of light then that would be OK. How would that work? Using the time/length dilation equations you end up with a negative square...

My teacher gave it to us. Not sure where he got it. Sorry but I don't have a scanner... Maybe someone else at school will be able to get it scanned

i have a copy of the ruse 2003 trial, but no solutions... can anyone help me out? thanks

In response to what Huy said: i'm not trying to create a nuissance of myself - that is why i asked for ideas that weren't considered vandalism, i don't want to damage the computers or just randomly screw them up - im just looking for a few jokes to play. compared to other things that are...

it's taken a while but a lot of effort is about to pay off and i should have the admin password for our school network. what ideas to ppl have about muckup day pranks? im looking at pranks rather than vandalism, but im sure ppl would be interested to here the more extreme stuff anyway. my...

it was baulkham hills... set by our own teachers. it wasnt a particularly hard test tho

i got 96/101. dats wat happens when i have a whole week to study nothing but 3u. but my guess is that im still ranked about 10-20th in the grade.

so what option would that be ragerunner? the michelson + morley stuff sounds vaguly familiar...

damn. that shits me pretty hard... every other school seems to tell their students their ranking. and scholarship applications, etc all ask for your school ranking. my teacher said that because we goto a selective school our rankings aren't as meaningful, but to me if you have a high ranking at...

does anybody know exactly where this rule of the BOS is? i goto school with Exeter and when i spoke to our deputy thismorning he still refused to tell us. he says that our 'final assessment' is actully the HSC so the school doesnt have to tell us til then. he also reckons that even after the...

well for the first part of the question, proving that odd functions pass through the origin: using f(-a)=-f(a): f(0)=-f(0) 2f(0)=0 therefore f(0)=0 part two, showing that x is a factor of odd functions: since 0 is a root of odd functions, then (x-0) is a factor, so x is a factor... im...

listen to these people. your yr 11 marks count for ZERO of your HSC/UAI. i know teachers may look unfavourably on it, but i see no real reason why you shouldnt just start the yr 12 course now. grab a textbook and start reading/writing some notes for it. i've found that we have really had to...

dats funny. my software development + design teacher did that exact thing to my class today. our whole class scored between 70 and 85. she said that since it was a hard test she would just add 10 points to all our marks. when we said that was a stupid idea she said that it was good because...

im just wondering...i know that you can calculate e by finding the sum from 0 to infinity of 1/n!, ie 1/1+1/1+1/2+1/6+1/24.... does anyone know of a similar formula for pi?

yes i realised that i'd misinterpreted the question wrong. i had been thinking that the question implied that the angle at the vertex was a right angle. i asked my teacher about it and he said that it was a bad question. but when i got home i thought about it and realised we had both been...

A vessel is in the shape of a right circular cone with vertex downwards and axis vertical; the height of the vessel is 12m and the radius of its circular top is 8m. The vessel is being filled with water, the inflow of water is at the uniform rate 2m^3/min. When the height if water is 'h'...

at my school you just elect to do it. altho that is baulkham hills high, so perhaps other schools have different criteria. i think i remember someone from hills grammar saying that they needed to do a test before they could pick up ext 2... you'd really just need to speak to your maths teacher...

yep. thats about it. also, in last years HSC paper, there was a question talking about the errors. two people performed an experiment and got results. one person graphed and drew a line of best fit. the other the other just found the average of the results. You had to compare their methods...

one that threw a lot of people in my school was proving that odd functions pass through the origin. then the second part of the question was to show that x is a factor of odd functions.
