POPSQuantum Aspects of Game theory I like the way the author explained the ways in which Game Theory can be used to help business, as well as the ways managers may misuse the theory. This is also a good model for teachers to use when developing a plan to implement standards, teach content, affect student behavior and more. One problem with using any model, is trying to cherry pick the "best, right" answer to a particular circumstance and not deviating from the plan, even when the scenario changes. As the authors state so well, the best way to use Game Theory is to develop a "...range of outcomes". As teachers get closer to the points where the various outcomes diverge, there is usually more data that can be used to revamp the model and hone in on the point of actual reality.

POPSGravity Mysteries: What is Gravity? There are still two problems with this, though. First, we have yet to find any proof of the existence of these hypothetical particles, which have been dubbed "gravitons". Secondly, when quantum field theory is applied to gravity, it is prone to give nonsensical answers to straightforward questions.

POPSDoes Death Exist? New Theory Says 'No' This was clear with the death of my sister Christine. After viewing her body at the hospital, I went out to speak with family members. Christine's husband - Ed - started to sob uncontrollably. For a few moments I felt like I was transcending the provincialism of time. I thought about the 20-watts of energy, and about experiments that show a single particle can pass through two holes at the same time. I could not dismiss the conclusion: Christine was both alive and dead, outside of time.

POPSDid You Hear The One . . . "He joked about linear regression (a rumination about what kind of people post cat videos on YouTube), period doubling in chaos (which he likens to the splitting of behaviors of people as they become more and more drunk) and the Heisenberg uncertainty principle. He explained this fundamental concept of quantum physics — that the more precisely the position of a particle is measured, the less is known about the particle’s momentum, and vice versa — with a photograph of a men’s room with television screens above the urinals. The designer “clearly didn’t understand the uncertainty principle,” Dr. Lee said."

POPSSeattle Translation Workers Remember Richard Feynman According to Seattle Translation workers, he believed the day would soon come. Of course, today consumer electronic enthusiasts are struggling to fill up their latest iPod or similar mp3 player with thousands of songs, videos and pictures that all fit snuggly in their pocket, gym bag or purse. While people are no longer interested in storing the Encyclopedia Britanica in a small space, language translation workers will certainly see new opportunities for these types of advancements

POPSBlack Holes May Act Like Cosmic Factories for Building Galaxies
The stream of material was likely to be fuelling star formation in the galaxy, the scientists believe. In effect, the quasar was building its own host galaxy. At a later stage the quasar was expected to end up at the galaxy’s centre. ‘The two objects are bound to merge in the future: the quasar is moving at a speed of only a few tens of thousands of kilometres per hour with respect to the companion galaxy and their separation is only about 22,000 light-years,’ said lead scientist Dr David Elbaz, from the CEA research institute in Saclay, France. ‘Although the quasar is still ‘naked’, it will eventually be ‘dressed’ when it merges with its star-rich companion. It will then finally reside inside a host galaxy like all other quasars.’ A similar process may have led to the formation of other large galaxies with massive black holes nestling within them, the scientists believe. The research appears in the journals Astronomy & Astrophysics, and the Astrophysical Journal.

POPSGetting Closer to String Theory Without string theory, physicists need two theories to explain how the universe works. General relativity explains gravity, while the other three basic forces are explained by the “standard model.” Moreover, gravity has been very difficult to reconcile with quantum theory, a problem for which string theory offers a solution.

POPSNew quantum algorithm helpes solving big problems. “Large-scale linear systems of equations exist in many fields, such as weather prediction, engineering, and computer vision”, says Harrow. “Quantum computers could supply serious improvements for these and many other problems. For example, a trillion-variable problem would take a classical computer at least a hundred trillion steps to solve, but using the new algorithm, a quantum computer could solve the problem in just a few hundred steps”. The solution could also be applied to other complex processes such as image and video processing, genetic analyses and even Internet traffic control. Sounds pretty good to me!

POPSThe life of Albert Einstein - He is best known for his theory of relativity and specifically mass-energy equivalence, E = mc2. Einstein received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect."

POPSDaniel Craig: see 007 again around November 2011 Did Daniel Craig made an intentional mistake by letting the audience know that Bond #23 will start filming at the end of 2010. As according to Variety He made the comment when one of his fan asked him about the follow up of “Quantum of Solace” that was released in 2008.

POPSPhysicists Calculate Number of Parallel Universes
Think it's crazy? Check this out, then: To work these numbers out, Linde and Vanchurin looked back to the time shortly after the Big Bang, which they view as a quantum process that generated lots of quantum fluctuations. Then during the period of inflation, the universe grew rapidly and these quantum fluctuations were "frozen" into classical perturbations in distinct regions. Today, each of these regions could be a different universe, having its own distinct laws of low energy physics. By analyzing the mechanism (called "slow roll inflation") that initially generated the quantum fluctuations, the scientists could estimate the number of resulting universes at 10^10^10^7 (a number which is dependent on the model they used). However, this number is limited by other factors, specifically by the limits of the human brain. Since the total amount of information that one individual can absorb in a lifetime is about 10^16 bits, which is equivalent to 10^10^16 configurations, this means tha
