Crash

i think its the heavy metal concerts

Can you explain please

Yea i can remember doing this in High school, i could never get the lines right, as we used graphite insteasd of soot, and it would crack etc... What size is this mirror on the moon?

i feel you pain brother....... im beginning to think its caused by electrical appliances (wild hunch) cause i never get it when im out tramping,camping or diving etc, how long do these last for you? and do you find some more intense than others?

i dont know of any laser experiments using lasers in "space" but several have been done in vacuums, or particularily with EXTREMELY small amounts of atoms in a vacuum and hitting them with lasers

if time travel was possible, i dont know

each to their own

TLDR but ill go with the "crap" option, i think its nurture not nature that brings on this sort of behaviour

WTF??????? [edit] yes i am here if thats what you mean, but that also depends on where "there" is in your mind

I was never enthused about math i think its a rear thing, everybody needs it and thats the only reason its so popular

WTF? i dont get ya metjetisle

space is far from a vacuum or "extreme nothingness"

I gots the same prob as aommaster it gets really annoying sometimes

Its been known about for quite some time now "planet X" http://news.bbc.co.uk/1/hi/sci/tech/3514594.stm It dosent fall under the current classification of a planet though

i once got to see an Argon ion laser (at otago university), it was awesome the guy using it there had heaps of scares on his hand (for obvious reasons)..... Is the "double slit" thing demonstrating the diffraction grating idea?

but im not having one straight pole in the center its gonna be two (some problems here)

the least of all sciences [oops] in university its essential you have a good grasp of calculus....not that i do

In high school? this would only be good if you did not want to further your learning in Physics, as neurocomp said "Its one of the principal foundations of modern physics."

"Brief history of time" is by stephen hawking, and is very helpfull

NO, it behaves like waves in wave experiments, and it behaves like a particle in particle experiments. Its still considered both at the same time but not like how you put it.....as for the idea of having to have a medium thats rubbish as long as your willing to abandon half of newtonian mechanics in order for the more new rewritten concept BTW read "brief history of time".........it helps

am i allowed to use a galvanic cell? say Zn/Cu or ferris ammonium sulfate? weigh under 250gms you say........

i used H2SO4 for the acid , i got it out of a car battery

well i guess time will tell, im half way through the second one (the first one broke) although im inclined to go with Sayonara on this one

i thought sharks only rested as such and not actually slept?

hope it works this time [edit] yea it works, the electrodes are from D battery cells,and the rest is straight foward
