Quantum Theory

I had another wild hair idea and started researching our best visual microscopes. The charge-coupled devices can see down to .2 micron resolution which means the sample has to be 20 microns for its shape to be discerned. It uses white light with a mid wavelength of 500 nm. Since atoms are around .1 nm dia. a one wave pulse of photons at it would have the atom moving all around between the first and last photons bouncing directly off it. With our computers getting faster all the time do you think we could actually receive the reflection and compensate for the waves length and get better resolution or even a few thousand clear pictures? Just aman

I have read somewhere that it is hard to identify the phenomeon of Quantum Mechanics. Althought i have read data about it, i still could not get the theory part. Can anyone give me examples of Quantum Mechanics happening or taking place in our daily lives or whatsoever. So, from iwhat i've read, Quantum Mechanics is the internal "factory" of an atom right? i only get the very thin surface of the meaning. The rest was like me looking at rubbish, pointless.

Just out of curiosity i would like to know what everyone thinks of this idea: there exists 2-kinds of electrical current, positive and negative, positive is the type in use worldwide today, a negative current exhibits unusual effects: 1)produces below ambient temperatures when present in(around) conductors. 2)an electric shock produces "frost" and a cold feeling in the human body. 3)electric lamps connected to a shorted out load illuminate. 4}exhibits "skin effect" at low frequencys. The inventor Nikola Tesla discovered this energy in the 1890's while observing the effect of sudden abrupt dc capacitive discharges(impulse), and described the effect as like a his…

Correct me if I'm wrong. Boiling is when all the particles in a liquid have enough energy to escape. If this is so, why doesn't the liquid boil off all at once. ie it disappears instantly when it reaches boiling point?

I have found out that the reason for letting the photons in by the atmosphere and not letting 'em out - is the fact that the reflected photons have changed their wavelength and frequency. Can anyone tell me how exactly that happens? Thanks.

Can electrons orbiting a stable atom e.g oxygen (that is not radioactive) be considered as perpetual motion. If no, why?

Do scientists know exactly the mechanism by which photons are quantumly entangled? I've heard reports that they "communicate" with each other at +c speeds. Do they know how this works? In the experiment performed with entangled photons traveling through sheets of metal [Nature (vol 418, p 304)] the photon was converted to electron waves which passed through the metal, then re-emitted the photon on the other side, which was still entangled. How are they entangled, and how would this entanglement remain in tact with the electron waves?

I looked at all the different forums and found this one to be the best. I have 1 question on light When light enters through a prism and bends, it is actually slowing down, now where on Earth does it get the energy to speed up again after it exits the prism

If so, how? And if not, why? I can handle a fairly complex science and/or math. But, of course, the simpler the better.

Can anyone please explain?

Supposing we put the Schrodingers experiment on a space ship and sent it of with the crew at 99-9% of c. Suppose that the box could be observed from earth by an inteligent robot. After an hour for the box and the comparible years on earth for the robot, the crew open the box to collapse the probability and see one state for the cat. Now for the robot years have passed before the box was opened. This means for the robot the time of probability collapse was different from the crew. Imagine now thousands of robots in different locations in the universe observe the probability collapse at varying times. Because the space ship travels below c all the robots will eventualy see …

Prompt please references to works in which it was considered the Schrodinger equation with stochastic (random) Gaussian delta-correlated potential which time-dependent and spaces-dependent and with zero average (gaussian delta-correlated noise). I am interesting what average wave function is equal.

This SO cool: http://www.physics.hku.hk/~tboyce/sf/topics/wormhole/wormhole.html what do u guys think?

Prompt please where it is possible to find algorithm of the numerical decision of stochastic Shrodinger equation with casual potential having zero average and delta – correlated in space and time? The equation: i*a*dF/dt b*nabla*F-U*F=0 where i - imaginary unit, d/dt - partial differential on time, F=F (x, t) - required complex function, nabla - Laplas operator, U=U (x, t)- stochastic potential. Delta-correlated potential <U(x,t)U(x`,t`)>=A*delta(x-x`) *delta(t-t`) . where delta - delta-function of Dirack, A – const, <> - simbol of average, Zero average: <U(x,t)>=0 Gaussian distributed …

I recall, vaguely, an article I read a year or so ago where some type of experiment was being performed in which light was sent, maybe in a vacuum and the time it took to travel from the source to the target was recorded with syncronized clocks on both ends. It turned out that the light actually somehow reached the target chronologically before it was sent (according to the syncronized clocks). I don't remember the specifics though or what ever came of it. Ring a bell with anyone?

hi all. first post here. been browsing some posts for a while. i'm new to the whole quantum physics thing. i'm completely hooked. Can anyone recommend some good books for info on the subject? i just recently bought "Three Roads to Quantum Gravity" by Lee Smolin. this book is very informative and i don't bust a brain cell trying to understand it. also, if anyone knbows any cool sites with works on the subject as well would be appreciated. thanks

My views here may be uneducated or something-- but thats what forums are for, to learn. If we live in a 3D world, then all particles are 3D--- so is there any smallest particle, or does size go infinately smaller? See my idea is that if there is a smallest particle, wouldn't it be indestructable or something, because how would you break it down? A theory I set forth acording to this, which is probably wrong but I don't particularly care : what if the 'smallest' particle is a universe--- after that the orders repeat. Makes things easier anyway. There is infinate universes in everything, and we are one universe as some particle of an atom in a universe above our ord…

Can any body explain how/why the property of a particle is acquired at the time of measurement (this was stated when the property of EPR correlation was demonstrated on tv) rather than already been formed. I will appreciate any notes or a link for this.

How do you find the wave function of a particle in a black hole? Do you just use Schrodinger's Equation?

I am doing a presentation on a how to measure the wave function of a particle. I chose to do this, since I couldn't think of anything else but time travel. Anyway, do you think it would be feasible to describe how to measure the wave function of a particle in 10 slides? I think maybe 2 or 3 slides (i.e., Power Point slides) would be ideal, but I have to have 10. How about time travel? what 10 steps are there, to time travel...say to the future? the past?

neutrino hawe no weigh no charge.its going trough earth like trough vacume.then how we can detect it.i think if we cant use its energy because there isnt cinetyc energy without weigh(E=M.C.C)we should detect it by acumulating energy in it not by collising.so we may need to create instalation to boost over 100 TERA ELECTRON VOLTS(100 000 000 000 000 ) every single piece!!!! .that mean we should use energy of several nuclear bombs each minute.thats why first we shold solve problems with controled anihilation of matter and anti-matter. WHAT U THINK GUYS????

when one looks at quantum and classical logic, there are a number of notable differences, and the two don't really seem to match. does anyone have any thoughts on why, and what the problems are with existing theory?

I am developing a theory. I have derived a simple trigonometric formula that yields the exact values for every line in the Lyman series for the hydrogen atom. My values match experimental values exactly. Check it out: http://24.236.152.228:65333/A%20Unification%20Theory_d1.htm

What, may I ask, is poise? (i.e., the physics definition).
