"Quantum Life: How Physics Can Revolutionise Biology" tonight, March 2, Saturday, 7pm @ Price Chopper. This sounds very interesting. Don't miss it! JOIN US--RSVP @ http://www.meetup.com/skeptics-137/events/104879352/
Presented and moderated by our own local Kansas Citian Dr. John Millam. Dr. Millam received his doctorate in theoretical chemistry from Rice University in 1997, and currently serves as a programmer for Semichem in Kansas City. He is an Evangelical Christian and is active at Olathe Bible Church.
In this video lecture at the Royal
Institution, Professor Jim Al-Khalili explores how the mysteries of quantum theory might be observable at the biological level.
Jim Al-Khalili is an Iraqi-born British theoretical physicist, author and broadcaster. He is currently Professor of Theoretical Physics and Chair in the Public Engagement in Science at the University of Surrey. He has hosted several BBC productions about science and is a frequent commentator about science in other British media. He currently presents the weekly radio 4 programme, "The Life Scientific", on BBC Radio Four. He is also President of the British Humanist Association.
Although many examples can be found in the scientific literature dating
back half a century, there is still no widespread acceptance that quantum mechanics -- that baffling yet powerful theory of the subatomic world -- might play an important role in biological processes. Biology is, at its most basic, chemistry, and chemistry is built on the rules of quantum mechanics in the way atoms and molecules behave and fit together. As Jim explains, biologists have until recently been dismissive of counter-intuitive aspects of the theory and feel it to be unnecessary, preferring their traditional ball-and-stick models of the molecular structures of life. Likewise, physicists have been reluctant to venture into the messy and complex world of the living cell - why should they when they can test their theories far more cleanly in the controlled environment of the physics lab? But now, experimental
techniques in biology have become so sophisticated that the time is ripe for testing ideas familiar to quantum physicists. Can quantum phenomena in the subatomic world impact the biological level and be present in living cells or processes - from the way proteins fold or genes mutate and the way plants harness light in photosynthesis to the way some birds navigate using the Earth's magnetic field? All appear to utilise what Jim terms "the weirdness of the quantum world". The discourse explores multiple theories of quantum mechanics, from superposition to quantum tunnelling, and reveals why "the most powerful theory in the whole of science" remains incredibly mysterious. Plus, watch out for a fantastic explanation of the famous double slit experiment.
Afterward we'll go across the street to the Blue Moose for drinks.
