Fission And Fusion

Science & Reason on Facebook: tinyurl.com Physics (Chapter 1): Fission And Fusion. — Subscribe to Science & Reason: • www.YouTube.com • www.YouTube.com • www.YouTube.com • www.YouTube.com — Consider the earth and a rocket ship which are bound together by gravity. If it takes work or energy to pull them apart, then the binding energy is the amount of energy it takes to completely separate them. Similarly the binding energy in a nucleus is the amount of energy it takes to completely separate the protons and neutrons, (collectively called nucleons.) There are two forces acting inside the nucleus of atoms. The nuclear force — a residuum of the strong force that holds quarks together — is pulling the neutrons and protons together — and the electric charge on the protons is pushing them apart. The strong force is a lot stronger than the electric force at short ranges up to two and a half times the proton diameter, but at larger distances the electric force dominates. This increase in binding energy continues until we get to iron and nickel where the nucleus has about 60 nucleons in it. At this point, the nucleus has a radius more than two and a half nucleons wide, which you remember is the range at which the repulsive ElectroMagnetic Force begins to dominate.. . So as we add nucleons past this point the electric force trying to tear the nucleus apart starts winning and each added nucleon is a little less-tightly bound. — The Cassiopeia Project is an effort to make high …

The Mystery of the Missing Mass

A film about Dark Matter – Dr Tara Shears explains why scientists think that most of the mass in the universe is made up of something we can’t see and how a new experiment called the Large Hadron Collider might finally tell us exactly what this “Dark Matter” is.

The world’s largest particle physics laboratory is under construction on the border between Switzerland and France. At the heart is the Large Hadron Collider Particle Accelerator being built by the European Organization for Nuclear Research (CERN). Its members hope it will reveal secrets of the universe and its formation. The goal of the project is to discover the origin of matter by replicating conditions just after “the big bang.” Twenty nations and international bodies make up CERN. Last April, scientists and journalists gathered at its Swiss headquarters, as the last of 1700 huge magnets was lowered into the Large Hadron Collider or LHC. CERN Director General Robert Aymar said, “It is an enormous task, with very tricky logistics, because the tunnel is very narrow, and when we move the magnets in nobody can be in the way.” The particle accelerator and collider is a 27 kilometer tunnel, about 100 meters underground. CERN spokesman James Gillies describes the accelerator. “This is a discovery machine. It’s built to make discoveries and is going to tell us lots of new things about the universe.” If all goes as planned, subatomic particles will be accelerated around the tunnel next year, eventually approach light speed, and smash into one another. Gillies adds, “To me the most exciting thing is that we know an awful lot about a small amount of the universe. We understand the stars, the galaxies, the stuff which makes up you and me, but we also know from cosmology that is …

think back to when you saw your first magic trick and how amazing it was until you found out how the trick was done !

The Invisible Beauty

For the Beauty that cannot be seen, For the honor of those whose shoulders we stand on, For the hope of those we aspire to become, And for the inspiration of those who will surpass our achievements. Music, beginning Omnibus End Music, Miles
