POPSQuantum Physics.. What it is? Quantum physics is a branch of science that deals with discrete, indivisible units of energy called quanta as described by the Quantum Theories. Quantum physics invloves the study of the realm of the very small, at the atomic and subatomic level, such as electrons, photons and quarks. Therefore, it’s operating at the below-cell level of the body. Quantum Physics is also the study of the forces that act on atomic and subatomic entities. There are 4 forces: gravity, electromagnetism, the strong force (binds particles in the atom’s nucleus) and the weak force (responsible for radioactive/beta decay). Quantum Physics also studies the fields through which forces move. Example of fields are the gravitational field and electromagnetic field. A field can extend throughout a large region of space so that its influence is all-pervading.

POPSMarcelo Gleiser on How do We Know? I encourage to read the original post and the comments that follows. It seems there is no end to our findings. The more sophisticated our instruments get, the more we find...from atoms to subatomic particles to higgs bosons. We become more conscious in the whole process. Is there really and to it?..Or is it our consciousness which gives our sense of reality without an end !!!

POPSEinstein's Relativity Theory Proven
So far so good, but here's where things get odd. Gluons have absolutely no mass, while the total mass of the quarks only represents 5% of the mass of the protons and neutrons. So, an explanation for the missing 95% of the mass had to be found. The experts discovered that the missing percentage of the mass derives from the energy resulting from the interactions and movements of the quarks and gluons. This basically states that mass and energy are equivalent, just like Einstein's theory indicated, and, even more: mass can be transmuted into energy and vice versa. Extrapolating on the basis of this equation, it can be calculated how much energy is obtained while converting specific amounts of mass. Sadly, this was also used as a ground for building the atomic bomb. "Until now, this has been a hypothesis," shared the National Center for Scientific Research (CNRS) in France in a press release, cited by Discovery. "It has now been corroborated for the first time."

POPSEntangled Particles and Free Will My Unitarian Universalist pastor just gave a sermon on this very "problem." It is mind blowing to think that the entangled particles communicate at a rate faster than the speed of light.

POPSLarge Hadron Collider Stalled till Spring '09 This must be frustrating for physicists who have waited decades to smash particles together in exciting new ways. But those of us with (scientifically debunked) fears of being swallowed by an LHC-triggered black hole can breathe a sigh of relief. For now.

POPSFermilab Looks for Visitors from Another Dimension The prospect of extra dimensions is fascinating. ET might already be here in a neighbour dimension. :-) Estimated to cost about $15 million, the MicroBooNE tank would be located near the MiniBooNE detector at Fermilab so that it could observe the same beam of neutrinos. This past June the lab’s physics advisory committee approved the design phase for the project; if all goes well, the detector could begin operating as soon as 2011.

POPSDo subatomic particles have free will? But physicists all the way back to Einstein have been unhappy with this idea. Einstein famously grumped, “God does not play dice.” And indeed, ever since the birth of quantum mechanics, some physicists have offered alternate interpretations of its equations that aim to get rid of this indeterminism. The most famous alternative is attributed to the physicist David Bohm, who argued in the 1950s that the behavior of subatomic particles is entirely determined by “hidden variables” that cannot be observed. Conway and Kochen say this search is hopeless, and they claim to have proven that indeterminacy is inherent in the world itself, rather than just in quantum theory. And to Bohmians and other like-minded physicists, the pair says: Give up determinism, or give up free will. Even the tiniest bit of free will.

POPSThe World's Largest Particle Accelerator No one really knows what the machine will give birth to. But the equations suggest that some weird stuff could be just around the corner — maybe "dark matter," the invisible stuff that seems to hang around galaxies. "It's kind of an embarrassment that we don't know what 95 percent of the universe is made of by weight," Green says. "We hope — it's possible — we may be making dark matter." Some theories say it is possible the collider will cause miniature black holes to momentarily appear. But for now, what has appeared is a table of croissants, an urn of coffee, and more people. Everyone stands around in blue hard hats. They don't talk about black holes or dark matter. A few say things like "I hope the magnet doesn't fall."
