The Standard Model Explains Force And Matter By Best0fScience The Standard Model of Particle Physics (Part 2): Force And Matter --- • http://www.youtube.com/Best0fScience • http://www.youtube.com/FFreeThinker --- The Standard Model of particle physics is a theory of three of the four known fundamental interactions and the elementary particles that take part in these interactions. These particles make up all visible matter in the universe. The standard model is a gauge theory of the electroweak and strong interactions with the gauge group SU(3)×SU(2)×U(1). Every high energy physics experiment carried out since the mid-20th century has eventually yielded findings consistent with the Standard Model. Still, the Standard Model falls short of being a complete theory of fundamental interactions because it does not include gravitation, dark matter, or dark energy. It is not quite a complete description of leptons either, because it does not describe nonzero neutrino masses, although simple natural extensions do. http://en.wikipedia.org/wiki/Standard... --- Down to the Small Consider a piece of matter, and imagine taking it apart down to its basic constituents the particles that make it up. Down to the atoms ..and further down to the protons, neutrons ... and finally to the quarks and electrons. If our hands were small enough, we could hold them in our hands as well. As we take matter apart down to the smallest scales, we must pass through levels of structure that are only possible because of FORCES that hold these structures together. The proton and electron for example are attracted to each other ... and that force of attraction is what holds them together in the atom. But what is it really that causes this attraction. How does the electron know the proton is there and what draws it towards the proton? How does the electron know not to be attracted to the neutron? The answer is that the electron and the proton each fill the space around them with countless millions of other tiny particles that have only the most ephemeral existence. Because it is electrically neutral, the neutron does not. These particles come into existence only briefly and are gone ... only to be replaced by another one thrown out by the parent particle. On this scale, the tiny bit of energy that is needed for their existence can be created out of ... NOTHING. But they also MUST DISAPPEAR in the briefest instant because the energy used to create them can only exist for a very brief instant. You can imagine these virtual particles as balls tethered to the parent particle by a rubber band and snapping back to the parent when they disappear. If one or more of them should encroach upon the territory of virtual particles tethered to another parent particle, they can get entwined and exchanged. Such an exchange is felt by the parent particles as a force. --- The Cassiopeia Project - making science simple!

RACING TO FIND THE GOD PARTICLE By thethinkingblue A very interesting program on linktv called International Dateline. This eposode is about the God Particle: Physicists from all over the world are racing to prove the existence of a particle that's surmised to be at the heart of the matter. Literally. Dubbed the "God particle" by Nobel Prize-winning physicist Leon Lederman, the Higgs boson is a controversial particle believed to bestow mass on all other particles. ____________________________________ About International Dateline on: http://www.linktv.org/programs/date_67 SBS Dateline, which began in 1984, is Australia's longest-running international current affairs program. It has a well-earned reputation for authoritative and incisive reporting. Dateline has taken the traditional way of producing TV current affairs and turned it on its head. Reporters who used to travel with a cameraperson and sound recordist now travel alone and have the responsibility of both filming and reporting their stories. The reporters became video-journalists gaining access to people and places that the conventional camera crews cannot.

The Elegant Universe: Einstein's Dream String Theory Clip By mayushkar Modern physics is composed of two theories that are ferociously incompatible—reached its schizophrenic impasse: one theory, known as general relativity, is fantastically successful in describing big things like stars and galaxies, and another, called quantum mechanics, is equally successful in describing small things like atoms and subatomic particles. Albert Einstein, the inventor of general relativity, dreamed of finding a single theory that would embrace all of nature's laws. But in this quest for the so-called unified theory, Einstein came up empty-handed, and the conflict between general relativity and quantum mechanics has stymied all who've followed. That is, until the discovery of string theory.

The Elegant Universe: Welcome to the 11th Dimension Clip By mayushkar In 1995 Edward Witten of Princeton's Institute for Advanced Study revolutionized string theory by successfully uniting the five different versions into a single theory that is cryptically named "M-theory," a development which required a total of eleven dimensions. The new eleventh dimension is different from all the others, since it implies that strings can come in higher dimensional shapes called membranes. These have truly science-fiction-like qualities, since in principle they can be as large as the universe. A brane can even be a universe—a parallel universe—and we may be living on one right now. The theory is so far ahead of experimental technique that there is as yet no way to verify whether strings are real or a figment of some very creative imaginations. But scientists at the CERN atom-smasher on the French-Swiss border are working to test of one of the predictions of string theory. Scheduled to run later in this decade, this experiment may take an important step in showing that string theory is not just a crazy idea.

He pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI). He is world-famous for writing popular science books and for co-writing and presenting the award-winning 1980 television series "Cosmos: A Personal Voyage", which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history. A book to accompany the program was also published. He also wrote the novel "Contact", the basis for the 1997 Robert Zemecki's film of the same name starring Jodie Foster. During his lifetime, Sagan published more than 600 scientific papers and popular articles and was author, co-author, or editor of more than 20 books. In his works, he frequently advocated skeptical inquiry, secular humanism, and the scientific method. http://www.carlsagan.com .
