The Second Law and Energy (second law event) 10/05/2007 1:00 PM Broad InstituteSteven Chu, Secretary of EnergyDescription: This Nobel Prize"winning scientist admits to staying up late the night before his talk to bone up on thermodynamics. He puts his research to good use, discussing the history and application of the laws of thermodynamics, which have served as "the scientific foundation of how we harness energy, and the basis of the industrial revolution, the wealth of nations." Taking Watt's 1765 steam engine, Stephen Chu illustrates basic principles of thermodynamics -- that energy is conserved, that you can do work from heat, especially when you maximize the difference in temperature in the system and minimize heat dissipation from friction. Chu offers another form of the laws: You can't win; you can't break even; and you can't leave the game. The game hasn't changed all that much in the past few centuries. credit MIT World -- special events and lectures license MIT TechTV

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble. One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well. Relativity of Simultaneity Since this extra dimension is so small, only tiny objects, such as particles, can move along it. Antimatter Retrocausality
General relativity General relativity, or the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1916[1] and the current description of gravitation in modern physics. General relativity generalizes special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations. Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light. Einstein's theory has important astrophysical implications. History[edit] Albert Einstein developed the theories of special and general relativity.
San Diego Tantra Community Calendar (San Diego, CA Please join us for Movie Night and Potluck. Potluck 6 - 7 pm. Movie & discussion 7 - 9:30 pm. The idea is that each month we present a different sexy, thought provoking, inspiring movie or film. Our movie of the month will be "SEXUAL HEALING ~ The Tantra Way", followed by an open discussion. This film is only 1 hour long, so there will be plenty of time for discussion. I am NOT charging a set fee for this event. BTW... same old location... Charles Muir is a delightful and inspiring teacher and healer!!! Recently I went to one of Charles Muir's lecture and puja events, and I won this DVD in a drawing, so I think the Universe dropped it in my lap so that I could share it with all of you in this group. Synopsis: This educational, profound and often humorous DVD presents renowned Tantra Master, Charles Muir (along with a panel of other presenters) addressing over 100 of the world's leading Tantra educators and sexual healers.
Physics World reveals its top 10 breakthroughs for 2011 The two physics stories that dominated the news in 2011 were questions rather than solid scientific results, namely "Do neutrinos travel faster than light?" and "Has the Higgs boson been found?". However, there have also been some fantastic bona fide research discoveries over the last 12 months, which made it difficult to decide on the Physics World 2011 Breakthrough of the Year. But after much debate among the Physics World editorial team, this year's honour goes to Aephraim Steinberg and colleagues from the University of Toronto in Canada for their experimental work on the fundamentals of quantum mechanics. Using an emerging technique called "weak measurement", the team is the first to track the average paths of single photons passing through a Young's double-slit experiment – something that Steinberg says physicists had been "brainwashed" into thinking is impossible. We have also awarded nine runners-up (see below). 1st place: Shifting the morals of quantum measurement
Welcome to Goddess Temple! Tantra Ads, Tantra Directory, Tantra Articles Quantum Diaries (Thoughts on work and life from particle physicists from around the world.) Naked Before God – Part 4 – Naked Prayer | All Things Rabyd If meditation can be done in the nude I think we can assume we might as well stay and pray in the nude. The two differ in this: meditation is about listening to God; prayer is about communicating with God. One is about listening; the other is about talking. Prayer is described in the Bible much like a subject in a kingdom coming into the throne room of the king and petitioning the king for favor and in return listening to what the king will grant and what he expects that subject to do if the king is going to grant that favor. Before I get into those qualities, I want to make my case for the home prayer and meditation room. The spiritual qualities of a person who prays are far more important than the wording of the prayer or doing things in the right order. 2) Persistence – “Ask and Keep on Asking…” Jesus words with the full Greek meaning indicate a persistence that needs to be present in prayer. Nudity is starting to show itself as a spiritual discipline. Next: Naked Worship Like this:
Gravitational lens A light source passes behind a gravitational lens (point mass placed in the center of the image). The aqua circle is the light source as it would be seen if there was no lens, white spots are the multiple images (or Einstein ring) of the source. A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer, that is capable of bending the light from the source as the light travels towards the observer. This effect is known as gravitational lensing, and the amount of bending is one of the predictions of Albert Einstein's general theory of relativity.[1][2] (Classical physics also predicts the bending of light, but only half that predicted by general relativity.[3]) Although Einstein made unpublished calculations on the subject in 1912,[4] Orest Khvolson (1924)[5] and Frantisek Link (1936)[citation needed] are generally credited with being the first to discuss the effect in print.

Nudity and the Roots of Compulsion | A Naturist's Lens I have to admit it, there is something that “pulls” at me when it comes to nudity. Yesterday’s post looked at how I entered into the world of naturism as a healing escape from a world that was closing in on me, pushing me into darkness, strangling the will to live at times. As I was reading last night before going to bed, I found these words. “You have to make your own world, instead of succumbing to the one that presses on you.” My entering into the trees and removing my clothing was a deliberate act of making my own world, a private world in which I could feel the sun, feel freedom; a place that was private outside of my skin. For many years while I was involved with my career as teacher, principal and counsellor, and busy with raising a family; occasions of nudity were infrequent, more like stolen moments. Time has a way of having us return again and again to our denied shadow stuff.
