A good website on quantum mechanics: http://en.wikipedia.org/wiki/Quantum_mechanics\n\nAlso, if you are intrigued by the cosmological theory of the universe, The Life of the Cosmos by Lee Smolin is an excellent read.

Currently not possible. Scillicon is not the most efficient but its abundance on earth is amazingly practicle. They've found ways to use nickle for example that can be 1000 times faster, but they'd have to reconstruct all the mechanism of the computer. \n\nnewscientist.com search quantum computer\n\nhttp://www.google.com/search?q=site:newscientist.com+quantum+computer

well optimization is used by companies to get the most amount for their money. (highest volume using lowest surface area). theres differential equations that model population and waves and transients in circuits. \nif you wantto be technical, then quantum mechanics describes everything using a differnetial equation (schrodinger wave eq).\num 1 of the easiest would be measuring speed and acceleration. as in if you know your position over time, then you can find your speed by differentiating and acceleration by differentiating again.\n\nlook in any calculus text book at the questions and there are a lot that give you a real world situation. i dunno. hope that helped.

We use technology based on quantum physics every day.  From your computer processor to MRI machines, it's been very useful.  However, we're not done formulating it completely - we know it works, but there are many different versions that are mostly completementary that produce the same results, and we still need to figure out how they fit together.\n\nThat said, "What the Bleep do we Know" is mostly crap.  From the parts that I saw, I wouldn't trust that movie to explain anything about science.  For instance, writing words on bottles of water and expecting it to change the taste is obviously nonsense.  I'm shocked they tried to pass it off as science.\n\nYou might just want to open a physics book instead if you want to know more about QM - don't trust the movies.

Nope.  You'd have to INVENT the thing, and nobody would use it.  \n\nBut PRINT out the thing, then SCAN that into your computer. \n\nGood luck and Happy Computing!

B only seems impossible because you're looking at it from a small, everyday perspective.  Read a book on quantum phenomenon and you'll discover that particles literally appear out of no where everyday, and we take this as completely normal.  The Universe and Everything is far more sophisticated than you're giving it credit for.

Quantum\n- a discrete amount of something that is analogous to the quantum in quantum theory\n- (physics) the smallest discrete quantity of some physical property that a system can possess (according to quantum theory)

write a program which will read the number as units,10's,100';s,1000's,10000's,100000's,1000000's,100000000's etc and store appropriate in english.  refer it and print eg.\n\n123 to print as one hundered and twenty three\n\n3  ---> store as three in a unit table  (3 is in unit, so read as three)\n2 ----> store as twenty in a ten table (2 is in 10, so read as twenty)\n1 ---->  store as one hundred in hundred table  (1 is in 100, so read as hundred)\n\nthen concantenate from the left\ni.e. one hundered twenty three \n\nadd only in the end\n\nwrite a program.  use brain to write the program.  there are so many ways, so many logic.  never post this type of question.\n\neach person's logic vary.  may be there will be very easy way of doing it.   and this program is very old.  this may have been written by innumerable number of programmers.  \n\nbye

Read "Applied Cryptography" by Bruce Schneier - It's a comprehensive academic survey of the field of Cryptography. \n\nIf you want to have real fun, why not take a look at Stephen Wiesner's work on 'quantum money', and the extension of the concept to 'quantum cryptography'. I'm sure you can Google up references!

I don't know what your interests are, but one experiment that I have done in the past is building an electric motor.  It's easy and does not require a lot of equipment.  I'll include the equipment list below.  If you are interested, send me an email and I will send you a picture of the setup.  That would be easier than explaining it here.\nEquipment required:\n1)Small stable platform, like a wooden board (maybe like 6 inches long and 4 inches wide, and perhaps like 1/2 inch thick).  Maybe a piece of cardboard would work as well.\n2)Magnet (something like 1 inch by 1 inch and 1/2 inch thick)\n3)Copper wire with a small diameter (something you would be able to wrap around your fingers)\n4)6-Volt battery (might be called a lantern battery). The shape of the battery is rectangular and the battery terminals look like little springs at the top of the battery.\n5)Two paper clips\n6)Two thumb tacks

a molecule can act like a silicon chip, when electrons in the orbitals are spinning in their fixed directions. by placing electrons into certain spins, data can be stored like a binary code. thats what quantum computing hopes to achieve; building micro computers.

Not much;  quantum mechanics is pretty much taken for granted (by physicists, NOT philosophers!) as the framework of almost all of modern physics (but gravity's another story...).  In that sense almost all physics research these days is "quantum" physics.  However, there is still some interesting work being done with phenomena that are distinctly quantum mechanical, such as Bose-Einstein condensation, quantum entanglement, and the like.\n\nI'd just like to point out that in the past 100 years since quantum mechanics was "born", no experiment has been performed whose results are not consistent with quantum mechanics.
