Is the Universe a Holographic Reality?
The Universe as a Hologram by Michael Talbot Does Objective Reality Exist, or is the Universe a Phantasm? In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century. You did not hear about it on the evening news. Aspect and his team discovered that under certain circumstances subatomic particles such as electrons are able to instantaneously communicate with each other regardless of the distance separating them. University of London physicist David Bohm, for example, believes Aspect's findings imply that objective reality does not exist, that despite its apparent solidity the universe is at heart a phantasm, a gigantic and splendidly detailed hologram. To understand why Bohm makes this startling assertion, one must first understand a little about holograms. This insight suggested to Bohm another way of understanding Aspect's discovery.
The Vega Science Trust - Richard Feynman - Science Videos
Chosen by the New Scientist - best on-line videos 2007. A set of four priceless archival science video recordings from the University of Auckland (New Zealand) of the outstanding Nobel prize-winning physicist Richard Feynman - arguably the greatest science lecturer ever. Although the recording is of modest technical quality the exceptional personal style and unique delivery shine through. Feynman gives us not just a lesson in basic physics but also a deep insight into the scientific mind of a 20th century genius analyzing the approach of the 17th century genius Newton. For the young scientist, brought up in this age of hi-tech PC/Power Point-based presentations, we also get an object lesson in how to give a lecture with nothing other than a piece of chalk and a blackboard. If you are unable to access the streaming video or would like a copy of the lectures, they are available from the University of Auckland, contact physics@auckland.ac.nz, or The Tuva Trader.

Gates Puts Feynman Lectures Online
MicrosoftThe new Tuva Web site features annotated videos of Richard Feynman’s physics lectures. Microsoft Chairman Bill Gates believes that if he had been able to watch physicist Richard Feynman lecture on physics in 1964 his life might have played out differently. Mr. Gates, of course, is legendary as a Harvard University dropout who went on to create the world’s most successful software firm. He has told associates that if had watched the lectures earlier in his life he might have become a physicist instead of a software entrepreneur. However, Mr. Microsoft Research announced on Wednesday that Mr. The name “Tuva” was chosen in reference to Dr. Mr. “I do think that making science cool to people when they’re young and therefore getting more people to go into it in an in-depth way, I think that’s very important right now,” Mr. The Tuva Web site will be expanded with additional Feynman lectures in the future, Mr. Mr. “I couldn’t help myself, I watched them one more time,” he said.

Supernova 1987A: The Three Ring Circus Week of March 6, 2000 Last week's Snack talked about why the star that was to become Supernova 1987a (what astronomers call the precursor) exploded. I concentrated on the core of the star, because for supernovae that's where the action is. I mentioned the outer layers a few times because they play their role in the explosion too: they provide the pressure for the core so it can fuse elements, and in the end it's the ejection of those outer layers that creates the supernova event. I didn't talk much about what those outer layers are doing while the core is going through its evolutionary gyrations. Again, my apologies. Once upon a time, say a million years or so ago, there was a star that would later be known as Sanduleak -69 202 (named after the man who catalogued stars in that region, and appended with its rough coordinates). As helium piles up in the core, it gets very hot. Nothing last forever, especially a star. That was in 1990.

Simple mechanisms explained
Email Below you’ll find animated diagrams and explanations of how various mechanisms work. Some of these have been crucial to major evolutions in mechanisms and technology, and allow us to do anything from fire weaponry to make cars move with the press of a pedal. Maltese Cross mechanism powers second hand movement in the clock: Radial engines are used in aircraft. Reciprocating movements power steam engines in locomotives: Sewing machine: Manual transmission mechanism, also known as “stick shift” is used to change gears in vehicles: This mechanism is called constant-velocity joint and is used in front-wheel drive vehicles: Torpedo-boat destroyer system is used to destroy fleet in naval military operations: The Wankel engine is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons: + Bonus – mechanism you can watch forever Leave your comment: You may also like these posts:
NASA Telescope Confirms Alien Planet in Habitable Zone
This story was updated at 12:15 p.m. ET. MOUNTAIN VIEW, Calif. — NASA's planet-hunting Kepler spacecraft has confirmed the discovery of its first alien world in its host star's habitable zone — that just-right range of distances that could allow liquid water to exist — and found more than 1,000 new explanet candidates, researchers announced today (Dec. 5). The new finds bring the Kepler space telescope's total haul to 2,326 potential planets in its first 16 months of operation.These discoveries, if confirmed, would quadruple the current tally of worlds known to exist beyond our solar system, which recently topped 700. The potentially habitable alien world, a first for Kepler, orbits a star very much like our own sun. "We're getting closer and closer to discovering the so-called 'Goldilocks planet,'" Pete Worden, director of NASA's Ames Research Center in Moffett Field, Calif., said during a press conference today. The newfound planet in the habitable zone is called Kepler-22b.
