Crash

speed is relative yes, but i was saying at zero movement would time cease to move foward or would it carry on as usual? I should refrase my last point in the previous post. time as seen from an observer appears to slow down for the person traveling.

good point. another thing that struck me about the movement thing is as we move even very slightly, we are traveling faster through time. the faster you move the faster through time you travel. Would there be a constant speed with which time would move at a minimum? weird hunch seems to fit into place....

Is time a consequence of movement? this thought struck me as i was walking to work yesterday. if the universe was static there would be no need for a fourth coordinate to specify time. although impossible to be static in the quantum realm, theoretically it everything was static would time move foward? and could you tell the difference between the two states?

Has anybody heard of this company and if they have what do they think of it, its a yanky company that makes health supplements and i was wondering what peoples thoughts and opnions are on it?

cheers all, i go for my MenzB shot in two days so ill get it looked at then

every time i have gone to blow my nose for the past three weeks blood has been coming out, ive never had nose bleeds before. i was wondering if anyone knew why this would be?

Not sure if this is chem or physics but i came upon it in a chem book so here it is, Is electron capture and positron emission the same thing? like what are they and how do they differ? also what is a negatron? Cheers

antone at all?

Anyone?

Im Having diffuculty in working out the nullity of a matrix, the matrix is a=[ 1,-1,1;-1,1,-1;1,-1,1] to find the nullity i was finding the eigenvalues and than working out the nullspace and than working out its dimension, is this correct? the other problem with this is i get to the polynomial equation from det(A-Lambda.I)=0 which ends up being -x^3 + 5x^2 -5x -1 which i dont think is correct, can someone please help. also can someone explain to me what multiplicity is? Cheers

Is it possible for humans to have too much sex? Is there any problems that arise from too much?

Dont know what my connection speed is, its through my uni. my top download speeds are well over 150 k/s. i know that its running through a fat fibre cable but i dont know what theyve regualted us to.

Could you suggest any good sites or books? Cheers

Ok, i got a couple of probs. how do i prove if a series is divergent or convergent? and what is the nth term test? can someone please explain it to me?

Cheers guys, ill let you know how i get on and hopefully post some good pics. **off to get webcam

I have a telescope, a Meade, D= 60mm, F = 700mm, f/11. In my astronomy class the other day my lecturer was explaining how to get a CCD chip out of a cheap camera and that this could be fixed on my telescope and then i could hook it into my computer and get alot more from my telescope (like colours of planets, as theyre too bright normally) so i was wondering if someone could tell me how and where on my telescope to fix this, also what are the specs of the camera that has a CCD chip in it should i get? BTW im a student, cant afford anything to expensive. Thanxs

Nah, i think NZ schooling is gay for lack of a better explanatiojn. plus we just got a new qualification system (NCEA) which is total balls, it failed in several other countries. we got introduced to hyperbolic trig in first year courses, but that was all, im only a first year but i taking the advancing second year paper what level of mathamatics is best for physics major? i suppose the best level you can attain?

ok, i got that down but im now stuck on damned complex roots, z=-16+i16sqrt3 so i polarise, get 32cissqrt3 z=rexp(i*theta) sqrt(3)/5 for the nth principle root and 2 for the radius but thats where my mind just dies on me, its too late to be doing this!!!!! Do maths degrees get easier or harder after second year?

i was squaring it because i started from the other side, is sinh(2x) not = (exp(x)-exp(-x)/2)^2 i was just thinking because sin(2x) can be img,(exp(ix))^2 sorry i meant 'so im guessing its like this', i was in a rush cause i had a lecture started in 5 mins. Cheers for the help to dude, to tired to do it tonight. ill prob be back tommorrow though

also how do you solve complex equations without de moivres, can someone give me a crash course pls?

you dont, you use a hyperbola as i said in my first post, same principal but use an inverse sphere as i said

with a circle, a line starting at the origin and heading out to the right side where the circle has a radius of 1 and sin being the lateral distance and cos being the vertical distance and tan being sin/cos and so on and so fourth for csch, sch, cot etc.

Um hyperbolic geometrey as opposed to "normal" geometry is based on hyperbolas instead of circles, say if trig is a sphere then hyperbolic trig is and inverse sphere sort of like a saddle

So im guessing its =(exp(x) - exp(-x)/2)^2 =(exp(-2x) + exp(2x)/2) =2sinhcosh Is that right? also what is the derivative of cosh^2(3x) and shine?
