Northwestern engineering professor Matthew Grayson discusses his role in bringing the Tony Award-winning play Copenhagen to the University. The play is set during World War II, when the friendship of two Nobel Prize-winning physicists is tested by the prospect of providing Nazi Germany with the atomic bomb. The production is part of a new outreach program at Northwestern, ETOPiA: Engineering Transdisciplinary Outreach Project in the Arts.

http://www.encognitive.com In quantum physics, the Heisenberg uncertainty principle is the statement that locating a particle in a small region of space makes the momentum of the particle uncertain; and conversely, that measuring the momentum of a particle precisely makes the position uncertain. In quantum mechanics, the position and momentum of particles do not have precise values, but have a probability distribution. There are no states in which a particle has both a definite position and a definite momentum. The narrower the probability distribution is in position, the wider it is in momentum. Physically, the uncertainty principle requires that when the position of an atom is measured with a photon, the reflected photon will change the momentum of the atom by an uncertain amount inversely proportional to the accuracy of the position measurement. The amount of uncertainty can never be reduced below the limit set by the principle, regardless of the experimental setup. A mathematical statement of the principle is that every quantum state has the property that the root-mean-square (RMS) deviation of the position from its mean (the standard deviation of the X-distribution): Delta X = sqrt{langle X^2 rangle-langle X rangle ^2 } , times the RMS deviation of the momentum from its mean (the standard deviation of P): Delta P = sqrt{langle P^2 rangle-langle P rangle ^2} , can never be smaller than a small fixed multiple of Planck's constant: Delta X Delta P ge {hbar over 2} The mathematical statement implies the physical statement. Once an observer measures the position of a particle with accuracy ΔX, the state of the particle immediately after the measurement has scriptstyle Delta P ge hbar /(2Delta X) . The uncertainty principle is related to the observer effect, with which it is often conflated. In the Copenhagen interpretation of quantum mechanics, the uncertainty principle is a theoretical limitation of how small this observer effect can be. A precise position measurement must alter the momentum by a large indeterminate amount, and vice-versa. While this is true in all interpretations, in many modern interpretations of quantum mechanics (many-worlds and variants), the quantum state itself is the fundamental physical quantity, not the position or momentum. Taking this perspective, while the momentum and position are still uncertain, the uncertainty is an effect caused not just by observation, but by any entanglement with the environment. http://en.wikipedia.org/wiki/Uncertainty_principle Author: TrungEdm Keywords: Heisenberg uncertainty principle physics quantum mechanics Added: April 21, 2008

Jeffrey visits with artist Gary LaCroix of Mammoth Arizona who has been producing transformational abstract surrealist paintings for over 25 years. Gary says this about his artistic exploration: As I have journeyed inward though spiritual paths, the intellect, psychedelics and meditation, one thing is evident; science and spiritually are converging realizing a holistic universe, holographic in nature. The concepts of reductionism, Newtonian physics and fundamental religions are being replaced by self-awareness and quantum physics. Heisenberg’s uncertainty principal, Bell’s thoughts on non-locality and Bohm’s implicate and explicate order, prove that we are a creative cause in the development of not only our lives but also the universe. We are undoing the beliefs of conflict, competition and separation — we are part of a whole. My paintings challenge the ego/mind to see the world differently. Look past your external projection and see inner space. Along with artist Mary Myers, Gary founded The Paradigm Shift Group in Oracle Arizona, home of The Biosphere 2 devoted to exploring new consciousness in a local salon setting. As the quote on their website states: We are living at a time of change. From the Newtonian View of separation or reductionism, to the quantum view of entanglement or cooperation. We are all connected the universe, the planet, and all who share it. An interesting dialogue with an artist who has devoted his art to exploring the invisible realms of consciousness and energetic fields that are best connected to through an open heart. Music today is provided by Podsafe Music Network artist Theatrimus playing his piece Slow Motion.

So we take a little break and all the creative juices leak into our shoes. Maybe if you give us a little cash-cash we'll start feeling the muse again: amazon.com/paypage/PM95XMPKXS9FL Or maybe just stop by the messageboard and give us some inspiration: jigsawfanclub.com/forumSee you in two weeks.
