What is quantum tunneling?Transcript: http://www.davidcolarusso.com/blog/?p=33#more-33 This video is an adaptation of an earlier piece of mine--Perspective on quantum mechanical tunneling. That film, however, was designed for a unique audience, and I felt its overall length was limiting its appeal here. So I've repackaged it as one of my weekly postings. I Hope you enjoy. People have been asking for the math. So here it is. The Sun's core temp is ~13.6 MK. For hydrogen nuclei the Coulomb barrier is roughly 0.1 MeV. This corresponds to a temperature in excess of 1 GK! Luckily, tunneling and the distribution of speeds among nuclei lower the actual temperature required. So without tunneling even the Sun's core isn't hot enough for fusion. To see most of this worked through, check out this link: http://burro.cwru.edu/Academics/Astr221/StarPhys/coulomb.html for a less mathematical explanation, try: http://en.wikipedia.org/wiki/Nuclear_fusion#Requirements Transcript: http://www.davidcolarusso.com/edblog/?p=41 The Tabletop Explainer is an intermittent educational vlog presenting answers to viewer questions, brief science lessons, and ideas for teachers and students. It is a feature of my blog "Tilts at Windmils" which can be found at http://www.davidcolarusso.com/blog/ Tagovi: physics quantum mechanics tunneling fusion potential energy star reality uncertainty measurement |

Quantum Mechanics for Dummies - Electrons Are WeirdClips from a BBC documentary explaining the arguments from the 1920's until now as to whether electrons are particles, waves or both. It outlines Einstein's distaste at Heisenberg's uncertainty principle and is a good starting point in realising that the universe is far, far stranger than can be imagined.

Quantum Of Solace Trailer (Bond 22)This is a fan trailer for the new upcoming Bond film, Quantum Of Solace. The film will pick up "literally an hour after" Casino Royale's conclusion, when a wounded Mr. White is shot and captured by Bond at Lake Como. Bond is then involved in a car chase in Siena, Italy. White reveals to Bond and M that his organization, Green Planet, has agents in Her Majesty's Government and the Central Intelligence Agency. Forensic evidence of an MI6 traitor leads Bond to Haiti, where he meets Camille, who then helps him find Dominic Greene, a ruthless businessman and a member of the organization. Greene intends to use his government contacts to help overthrow the current regime in a Latin American country, and place the exiled General Medrano as the head of state. Medrano will in exchange give the organization a barren piece of land, which actually will give them total control of "one of the world's most important natural resources". Bond travels to Austria and South America to unravel Greene's plan, staying one step ahead of the CIA, terrorists and M whilst trying to keep his desire for retribution over Vesper Lynd's death in check. Quantum Of Solace hits theatres everywhere on November 7th, 2008. Tagovi: Quantum Of Solace Trailer James Bond 22 Casino Royale Daniel Craig Marc Forster Spyderfan007 |

Quantum Computing Day 1: Introduction to Quantum ComputingGoogle Tech Talks December, 6 2007 ABSTRACT This tech talk series explores the enormous opportunities afforded by the emerging field of quantum computing. The exploitation of quantum phenomena not only offers tremendous speed-ups for important algorithms but may also prove key to achieving genuine synthetic intelligence. We argue that understanding higher brain function requires references to quantum mechanics as well. These talks look at the topic of quantum computing from mathematical, engineering and neurobiological perspectives, and we attempt to present the material so that the base concepts can be understood by listeners with no background in quantum physics. This first talk of the series introduces the basic concepts of quantum computing. We start by looking at the difference in describing a classical and a quantum mechanical system. The talk discusses the Turing machine in quantum mechanical terms and introduces the notion of a qubit. We study the gate model of quantum computing and look at the famous quantum algorithms of Deutsch, Grover and Shor. Finally we talk about decoherence and how it destroys superposition states which is the main obstacle to building large scale quantum computers. We clarify widely held misconceptions about decoherence and explain that environmental interaction tends to choose a basis in state space in which the system decoheres while leaving coherences in other coordinate systems intact.
