IST DIE QUANTENMECHANIK ODER DAS RECHNEN FUNDAMENTALER? Is quantum mechanics as currently conceived the ultimate theory of nature? In his book "Atomic Physics and Human Knowledge", Niels Bohr argued that because of the uncertainty principle quantum methodology might not be applicable to the study of the ultimate details of life. Delbruck disagreed, claiming that biosystems are robust to quantum disturbances, an assertion that is only partially valid rendering Bohr's argument still significant, even though normally ignored. The methods of the quantum physicist and of the biological sciences can be seen to involve two alternative approaches to the understanding of nature that can usefully complement each other, neither on its own containing the full story. That full story, taking into -

The SI assumes that our present knowledge is valid but it is understood that the sciences upon which it is based must be tested. The SI simply provides a system where we can compare results from around the world. The adjustment of the fundamental constants is the most stringent test we make of the system. -

Toward a Theory of Everything? Exploring at the Edges of the ERM Construct
Toward a Theory of Everything? Exploring at the Edges of the ERM Construct Dr. Kathleen Locklear 2012 Enterprise Risk Management Symposium April 18-20, 2012 © 2012 Casualty Actuarial Society, Professional Risk Managers’ International Association, Society of Actuaries Toward a Theory of Everything? Exploring at the Edges of the ERM Construct Dr. Kathleen Locklear Call Paper Submitted for the 2012 ERM Symposium April 18-20, 2012 Abstract During the past 10 years, enterprise risk management (ERM) has evolved considerably into a best practice approach for identifying, managing and monitoring risk across an entire organization. At the level of theory, ERM standards and frameworks such as those created by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and the International Organization for Standardization, have provided guidance and a direction forward. Nevertheless, there remains no single, universally accepted ERM framework. At times, the multiplicity of approaches to ERM can produce confusion, leaving companies and practitioners alike wondering which method is “right.” Moreover, despite advances in ERM theory and practice, transboundary risk, extreme events and emerging risk continue to stretch ERM to its limits. This “stretching,” in combination with other observations regarding the current state of ERM theory and practice, suggest limitations in the ERM paradigm as it exists today. This raises several compelling questions, which are the focus of this paper. 1) What is the current state of the ERM paradigm, -

Quantum Consciousness
OMNI Vol. 7 NO 12 SEPTEMBER 1985 CONTINUUM QUANTUM CONSCIOUSNESS I began my search for the ultimate connection between matter and consciousness nearly two decades ago, when the Age of Aquarius was in full bloom and I was a professor of physics at San Diego State University. There were drugs to be taken, life-style changes to be made, a war to protest, and liberated sex to be enjoyed. I embraced it all. By 1970 I had become disillusioned. I turned on, dropped out, and found myself involved with Eastern mystics, consciousness-raising groups, and others who were labeled New Age. During my year in France, as associate professor of physics at the University of Paris, I met and studied with the biblical scholar and cabalist teacher Carlo Suarès. I was also visiting professor at Birkbeck College, in London, studying with physicist David Bohm, who had similar interests. My mind reached out for understanding, and by 1974 I felt that quantum physics and consciousness were deeply connected. I began to realize that the brain may be governed by the laws of quantum physics rather than the laws of biology or neurophysiology. As a result, such feelings as love and hate, commonly thought to be God-given or incapable of scientific understanding, could be translated into the language of quantum physics. The only mystery of quantum physics lies in the wave-particle duality described by Richard Feynman, the Nobel prize-winning physicist. Atomic objects (electrons, protons, neutrons, photons, quarks, and so on) sometimes behave like particles, and other times, like waves.
