or you could drive to the sea with a bucket like i do.

i can send a message into space already. i just need to jack up the power to my antenna by a few kilowatts

Chemistry mistakes on TV - Have you got any to share?
insane_alien replied to RyanJ's topic in Applied Chemistry
in controlled doses of course -
yeah i know theres no physical contact but before i properly understood the process bumped was good enough so i still use it. old habits die hard.
-
i don't think its completely the second idea. its just that when an electron is shoved in one end of the wire electrons are "bumped" along the wire until another electron pops out the other side kind of like water in a pipe. i know that electrons are constantly randomly switching atoms
-
yeah but all that stuff is just a placebo

i just watch it for prof. miang lee -
WOOHOO! i got refered to! BOOYAH!
-
closer to the second but a mixture of both

AAAAAAHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! - you'll be getting the bill from my shrink

Good 'scientific' movies (new and old are welcome)

i thought it was a catamaran(sp? i mean two hulled boats). i could just have automatically thought it was one after not believing that it was standing upright with a single hull -
it happens when a high energy photon travelling near the event horizon splits into a matter-antimatter pair and the antimatter part falls in destroying a tiny bit of the black hole and the matter particle has enough energy to fly off into space. there is also hawking radiation but i don't know too much about that

gravity is the centripetal force in this case. as the earth wants to move in a straight line it needs a force acting on it to hold it in orbit around the sun. the only force that could be doing this is gravity as the earth and sun are not charged and the magnetic fields are negligible

Take a look at this paper about General Relativity
insane_alien replied to jcarlson's topic in Speculations
its damn near impossible to read. he changes the SI symbols for equations to other symbols so anyone with even a basic understanding of physics gets confused. -
at the south pole east and west are rotations not directions(or so i was told)
-
the reaction would be +dG and so is not feasible it violates a number of basic rules and laws

Whats the most dangerous chemical you have used / seen?
insane_alien replied to RyanJ's topic in Applied Chemistry
trinitrotoluene - most dangerous i have ever produced nitroglycerine - most dangerous i have ever seen -
Static electricity and mid-air refuelling
insane_alien replied to vrus's topic in Modern and Theoretical Physics
there was an experiment i did in highschool to show that charge can be lost to the surrounding air where we used some very thin insulating thread to hang a small sphere (resistance was on the order of tera-ohms) the sphere was then charged to 200V+/- 2V and left for 10 mins and we then measure the potential as 150V+/- 2 V the potential lost through the wire was something like 0.01V (teacher done calculations as we were too uneducated at that point) -
i read once( yeah i know that this isn't the best way to start) that the energies required to create a wormhole are the equivalent of getting a loop of neutron star matter 1m thick around the sun at a distance of 1 AU then spinning that ring till is tangental velovity is 0.999 c

you basically need a temperature difference to generate enrgy (i know the liquid nitrogen would provide this but it would cause the liquid nitrogen to heat up)
-
need specs about the engine and how much fuel is in the cylinder how much of it actuall burns. for the engine we need the volume of the cylinder when its at its smallest and we also need the temperature post combustion if you give us the precombustion temperature we can work out the post combustion temperature. we also need the pressure of the moment of combustion. we need more info basically

yeah like he wouldn't have hard copies, backup copies on floppies/CD/memory stick and remember it all. esp. if its such a world changing theory as well
-
highschool just now but i am studying for a masters degree in chemical engineering

probably from when i was around a year old. i was sitting in my garden staring at a cat that sat down near me. it was the most interesting thing in the world at that point. my next memory is smearing food all over my face (not quite sure if it was earlier or later but still when i was in nappies) and then one from when i was older and i was walking along a pebble beach with my family and i tripped and fell face first in the water despite the fact i had reins(a kinda harness thingy so i wouldn't run away from my parents, you know what kids are like when they first learn to walk) on.

its to do with atoms having more electrons having more electrons on oneside than the other. usually this is random and quikly equalizes but there are a few configurations of crystals where it practically forces them to stay more to one side. this is the extent of my knowledge on this subject and is probably woefully inaccurate. electromagnets on the other hand use an electrical current moving in a loop or coil to generate the field.
