Quantum Mechanics

www.myspace.com The Danish physicist Niels Bohr, who worked in Rutherford's lab, was the first to describe orbits of fixed size and energy in which electrons are free to travel without losing energy and falling toward the nucleus. According to this model, published in 1913, electrons can only occupy or jump between fixed energy levels and cannot reside in between these levels. In addition, once in their "ground state," electrons maintain the energy they contain. This energy keeps them in perpetual motion, allowing them to resist the attractive force of the nucleus.

Symphony of Science - the Quantum World!

mp3: bit.ly A musical investigation into the nature of atoms and subatomic particles, the jiggly things that make up everything we see. Featuring Morgan Freeman, Stephen Hawking, Michio Kaku, Brian Cox, Richard Feynman, and Frank Close. "The Quantum World" is the eleventh installment in the ongoing Symphony of Science music video series. Materials used in the creation of this video are from: symphonyofscience.com for downloads & more videos! Richard Feynman - Fun to Imagine BBC Visions of the Future - the Quantum Revolution Through the Wormhole with Morgan Freeman Into the Universe with Stephen Hawking Brian Cox TED Talk BBC What Time is it BBC Wonders of the Universe BBC Horizon - What Is Reality Special thanks to everybody who's donated to keep the project alive and to those who helped track down the materials used in this video. *Please note that dark matter and dark energy are considered to make up a majority of the universe, in addition to the 12 particles and 4 forces. Lyrics [Morgan Freeman] So, what are we really made of? Dig deep inside the atom and you'll find tiny particles Held together by invisible forces Everything is made up Of tiny packets of energy Born in cosmic furnaces [Frank Close] The atoms that we're made of have Negatively charged electrons Whirling around a big bulky nucleus [Michio Kaku] The Quantum Theory Offers a very different explanation Of our world [Brian Cox] The universe is made of Twelve particles of matter Four forces of nature That's a ...

What is quantum tunneling?

Transcript: www.davidcolarusso.com 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 Explainer episodes. 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: burro.cwru.edu for a less mathematical explanation, try: en.wikipedia.org 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 www.davidcolarusso.com

The Quantum Conspiracy: What Popularizers of QM Don't Want You to Know

Google Tech Talk January 6, 2011 Presented by Ron Garret. ABSTRACT Richard Feynman once famously quipped that no one understands quantum mechanics, and popular accounts continue to promulgate the view that QM is an intractable mystery (probably because that helps to sell books). QM is certainly unintuitive, but the idea that no one understands it is far from the truth. In fact, QM is no more difficult to understand than relativity. The problem is that the vast majority of popular accounts of QM are simply flat-out wrong. They are based on the so-called Copenhagen interpretation of QM, which has been thoroughly discredited for decades. It turns out that if Copenhagen were true then it would be possible to communicate faster than light, and hence send signals backwards in time. This talk describes an alternative interpretation based on quantum information theory (QIT) which is consistent with current scientific knowledge. It turns out that there is a simple intuition that makes almost all quantum mysteries simply evaporate, and replaces them with an easily understood (albeit strange) insight: measurement and entanglement are the same physical phenomenon, and you don't really exist. Slides are available here: docs.google.com Link to the paper: www.flownet.com About the speaker: Dr. Ron Garret was an AI and robotics researcher at the NASA Jet Propulsion Lab for fifteen years before taking a year off to work at Google in June of 2000. He was the lead engineer on the first ...

Power of Thought - A Quantum Perspective - By Kent Healy

A scientific approach to explaining the power of thought. We have all heard it before, "Your thoughts create your reality." Well, new quantum physics studies support this idea. Learn about recent research about how the mind can influence the behavior of subatomic particles and physical matter. If you enjoy the video, please pass it on to friends and family.

Quantum Levitation Demonstration at North Museum

The North Museum of Natural History & Science in Lancaster, PA previews its newest attraction: a quantum levitator. It's a circular track of magnets above which a razor-thin disc magically levitates, seeming to defy the laws of physics. Purchased for about $7000 from Tel-Aviv University, the levitator is believed to be the only one of its kind in a United States museum. The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of foam is placed on top and held in place with household plastic wrap. The disc is then dipped into a brew of liquid nitrogen (temperature: minus-300 degrees Fahrenheit).
