What do people have to say about quantum phsyics lately?

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.

Quantum mechanics deals with anything that can come in fixed quanta, which is basically everything if you get small enough!\n\nMass comes in its fundamental particles, but you have other fixed packets of energy that can be treated with particle behaviour.\nA photon is a packet of light.\nA phonon is a packet of vibrational energy.\nEven magnetic flux in a superconductor has a magnetic flux quantum.

New ideas and concepts in science have always been considered moving toward "psudo-science" until the ability to prove the new theory was achieved.  Finding a way to prove string theory, or anything else on the quantum level will be man's biggest challange, and we won't get there without philosophy.

Are you referencing the time dependency of the Schroedinger equation?  Or are you implying quantization of time?

Quantum Mechanics is the Physics behind Physics, it is Philosophy with Scientifical evidence, this goes beyond Logic and reasoning, and it only goes to show that the most incomprehendible thing about reality,(really is after all) the fact that it is comprehendible!!! I have yet to see the movie but the guy who said he and his chick tried to count how many errors were there within the first 15 minuites of the movie but couldn"t cause there were too many,.. yeah well,... He"s a fool if he disregards all things just as easily as he did this, I mean he counted the errors for example with our common (estimate his knowledge of this topic to a high level by the way, I am willing to assume he knows what he is talking about and what he is talking about is Physics, you know Science science,... I love that subject too,,,, but Quantum Mechanics is a modern Science, even more so and 10 fold than the one used for our latest and most newest forms of technology! \n  Ok please do me a favor and research when this subject first made it"s debut, and more importantly Who helped develop this Topic, and I am sure you will be surprised, For now I will give you one name, and it is one that by the way is not the father of this subject, but Albert Einstein himself, was there when they were cooking this Phenonmenal study up, it was a handfull, I mean a "handfull"! of the best most respectable minds of that time and we should be proud, ........ of our era,.......it brought me peace, when thinking about the Pi equation,...... it doesn"t gibe you an explanation Quantum Mechanics, it hardly gives you an understanding, but you do or can come to terms with the fact that life is not an answer it is a question, perhaps............

For those who understand mathematics, and dare to imagine beyond the usual, quantum mechanics could easily be the most beautiful branch of physics.\n\nQuantum mechanics is a fundamental branch of theoretical physics that replaces Newtonian mechanics and classical electromagnetism at the atomic and subatomic levels. It is the underlying framework of many fields of physics and chemistry, including condensed matter physics, quantum chemistry, and particle physics. Along with general relativity, it is one of the pillars of modern physics.\n\nQuantum mechanics was developed in the first part of the 20th century and was highly successful in explaining the behavior of atoms, molecules and nuclei. Developed between 1900 and 1930 and later combined with the general and special theory of relativity, it revolutionized the concepts of physics. The new concepts, which were the particle properties of radiation, the wave properties of matter, quantization of physical properties and the idea that one can no longer know exactly where a single particle such as an electron is at any one instance were necessary to explain all of the new experimental evidence that was available at the time. For example, quantum mechanics explains the behavior of semiconductors which are used to make the myriad of devices we use every day.\n\nFollowing are the important contributors to the foundation of quantum mechanics and the principles they uncovered.\n\nYear  Researcher    Quantum Mechanics Concept\n1901  Planck        Blackbody radiation\n1905  Einstein      Photoelectric effect\n1913  Bohr          Quantum theory of spectra\n1922  Compton       Scattering of photons off electrons\n1924  Pauli         Exclusion principle\n1925  de Broglie    Matter waves\n1926  Schroedinger  Wave equation\n1927  Heisenberg    Uncertainty principle\n1927  Davison and Germer  Wave properties of electrons\n1927  Born          Interpretation of the wavefunction\n\n[The answer given by the first user (theswarm666x) is foolish. Although, one gives such examples in order to explain students of quantum mechanics what is actually meant by the terms like 'tunneling', you could not and should not use quantum mechanics in such a situation. Quantum mechanics talks about the wave aspect of objects (which is significant only for very small bodies) and waves can travel through walls.]

A good book is called the new quantum universe.  You'll need to give yourself a bit of time to absorb all that information.  But it contains all the basic ideas, formulations and explanations to get started

Dear Madame,\n\nYou could try testing wave-particle duality nature of photons, and report on how the theory corresponds with Schodiger's findings in the early 20th century. \n\nAnyone can put a light bulb in a potato. Also, the above response about commercials is about as unscientific as you can get. I don't trust emus.\n\nPianoguy

“…the possibility of any occurrence happening to anything at any time…” I think you’re referring to the many-worlds interpretation of quantum mechanics but you’re putting the popular “new-age” spin on it. Quantum theory outlines the exchange of energy between the four fundamental forces and explains the interactions of these quanta with atomic and subatomic particles. Certain counterintuitive observations from the quantum world, or "quantum paradoxes," can be removed by invoking the many-worlds interpretation but it is still just an interpretation and it doesn’t really allow anything to happen anywhere at anytime. If you’d like a great introduction to this, try reading The Cosmic Banditos by A. C. Weisbecker.\n\nScientific theories will never capture God, they explain the phenomenological world not the spirit; quantum physics is science not theology. If you look for science in God, you’re looking in the wrong place. If you look for God in science, you’ll miss the whole thing.

(m)\n\nIn recent years physicists have had to address the interplay of consciousness and the physical world. In Quantum Physics much has been made over Bell's Theorem. The implications of this theorem and the experimental findings that flow from it are staggering. They force us to consider that the entire notion of a purely objective world is in conflict not only with the theory of quantum mechanics, but with the facts drawn from actual experiments. These findings point insistently to a profound interaction between conscious mental activity and the physical world itself.

Yes it just depends on what you beleive in and what you don't.  This kind of science is called quantum physics.  Check it out some time, it's very interesting.

It has allready been done. Particles have been 'transported' from one local to another. It happen ed when I wrote and answered this question, \n\ninformation was teleported, as were some atomic and sub atomic elements. \nRecent developments\n\nUntil recently, scientists had been able to transport only light or single atoms over short distances (millimeters). However, it was reported in October 2006 that Professor Eugene Polzik and his team at the Niels Bohr Institute at Copenhagen University in Denmark have made a breakthrough in the field.[3] Their experiment involved the transportation of information from one macroscopic atomic object containing thousands of billions of atoms to another, located half a meter away. The technique involved the use of quantum entanglement, quantum measurement and quantum feedback. Little information is available, however, which throws suspicion over what would otherwise be a great accomplishment.\n\n[edit] Davis report\n\nIn 2001, the United States Air Force commissioned Eric W. Davis, Ph.D., FBIS, to do a scientific study of teleportation.[4] The Davis report has been very controversial due to its recommendation of further studies of p-Teleportation:\n\n    A research program improving on and expanding, or implementing novel variations of, the Chinese and Uri Geller-type experiments should be conducted in order to generate p-Teleportation phenomenon in the lab.[4]\n\nThe report (page 2) classified teleportation concepts into five sections:[4]\n\nsf-Teleportation \n    "the disembodied transport of persons or inanimate objects across space by advanced (futuristic) technological means." The report does not further define sf-Teleportation, and has no further comment on it than to dismiss it from the scope of the report. This type of teleportation could use a physical connection between the two locations, such as a wire. Using existing technology, such as the Internet, or telephone lines, could be the means for this type of teleport. However, this means it would be extremely slow, since a typical living animal is approximately equal to 600YB (yottabytes). Compression could be utilized, but would have to be effective in keeping all data intact.\n\np-Teleportation \n    "the conveyance of persons or inanimate objects by psychic means."\n\nvm-Teleportation \n    "the conveyance of persons or inanimate objects across space by altering the properties of the spacetime vacuum, or by altering the spacetime metric (geometry)." This category includes the use of wormholes for transport, and the modification of the speed of light.\n\nq-Teleportation \n    "the disembodied transport of the quantum state of a system and its correlations across space to another system, where system refers to any single or collective particles of matter or energy such as baryons (protons, neutrons, etc.), leptons (electrons, etc.), photons, atoms, ions, etc." The report explicitly includes in this category a process essentially the same as that envisioned by the fictional transporters of Star Trek. It also includes quantum teleportation by means of quantum entanglement.\n\ne-Teleportation \n    "the conveyance of persons or inanimate objects by transport through extra space dimensions or parallel universes."\n\nThe report did not investigate sf-Teleportation other than to define it. The report recommended further study in all other types of teleportation (pages 28-29, 47-49, 54, 62).\n\n[edit] Teleportation scenarios\n\nThe use of teleportation as a means of transport for humans still has considerable unresolved technical and philosophical issues, such as exactly how to record the human body sufficiently accurately and also be able to reconstruct it, and whether destroying a human in one place and recreating a copy elsewhere would provide a sufficient experience of continuity of existence. Believers in the supernatural, such as religious people, might wonder if the soul is

Laney, first of all allow me to say that I'm incredibly glad and pleasantly surprised to hear of your genuine interest in this field.   You are to be truly commended for your intellectual courage and abilities.  ...But to address your question, there are in fact thousands of great explanatory/layman-type books out there on Quantum Mechanics, Field Theory, Gravity, Philosophy, Reality, and associated topics like cosmology, etc.  Some of them even dating back to the mid 70's, that nonetheless are still wonderful reads.  ...Theoretical physics at the level that we are talking about here, though, is unfortunately a seven-headed exotic mathematical monster that is not even accessible to most physicists, much less the lay person.   Having said that, and as you know, there have been courageous attempts by talented physicist like Brain Greene (and many others before and after him) to make our latest theoretical/scientific visions of the physical world/universe available to the general public.   ...Since you mentioned that you are NOT mathematically inclined, but did enjoy Greene's The Elegant Universe, the first thing that came to my mind (and the book that I would recommend most) was in fact Greene's newer work called "The Fabric of the Cosmos: Space, Time, and the Texture of Reality" - in case you haven't read it yet.    \n\nAmong some of the other more recent titles worth mentioning also are:\n\nThe Great Beyond - by: Paul Halpener (A very nice book)\n\nThe Cosmic Landscape - by: Leonard Susskind\n\nHiding in the Mirror - by: Lawrence M. Krauss\n\nThe Road to Reality - by: Rofer Penrose\n\nA First Course in String Theory - by: Barton Zwiebach (This is a very nice book but a lil' more mathematically oriented than you might enjoy - let's say undergraduate physics level) \n\nI also highly recommend:  The Five Ages of the Universe - by: Fred Adams\n\nThat should keep you busy for a while - Good Reading!  ;-)

Mit has open courseware on their website.  They've been videotaping the classes, but they don't have this for the quantum physics classes yet.  If you just want basic information, then you can check out some of the other physics.
