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 …

Terence Kealey gives a talk on why science is not a public good, and why it is be better off done in the private sector. In this part Kealey answers a question about whether the private sector would fund research into pure science subjects like number theory despite a seeming lack of immediate commercial applications.

Sorry about the take off its a download so it dosent work well.. PLZ ENJOY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! & ??????????????????? ??????????????????? ??????????????????? ??????????????????? PLZ PLZ PLZ PLZ PLZ PLZ SUBSCRIBE!

One of the Universe’s open questions maybe a step closer to be answered thanks to over 30 atoms of antihydrogen that have been trapped and stored by scientists at the European Organization for Nuclear Research, Cern. According to a written statement, this opens the path to new ways of making detailed measurements of antihydrogen, which will allow scientists to compare matter and antimatter, the latter being what annihilates ordinary matter in a single explosive flash of energy.

Equal amounts of matter and antimatter were created at the birth of the universe but there’s very little of it around today. Dr Tara Shears explains why this is one of the greatest mysteries in science and how it might be solved by the biggest experiment in history. To learn more, visit www.labreporter.com

Just using some tunes of the the 97′ techstep drum and bass era with its technological sci-fi sounds and metal futuristic alien sounds. The video is comprised of nasa space images which gives the theme of flying through space with eerie dark unknown sounds of techstep darkness. This mix is not about harmony in anyway or beat matching, it is just based on themes that sound similar but in one music session for youtube.

Comical Newsflash by Kaz Stevens: “Thatched-Roof first for Branston’s Space Tourism”.Back in the 1970′s I used to write political satire for TV programmes such as: “Not the Nine O’Clock News” “Spitting Images” (Early episodes) “Secret Policeman’s Ball” (Amnesty International) “The Two Ronnies” (Comical Newsdesk Sketches) Today I am building a showcase for my work at: www.all-things-zany.com This clip is to be one of a new series of comical newsdesk sketches written and recorded by me.
