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. Today, however, most aircraft use turbine engines: 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:

Physics Equation Solvers | Blue Solver Open Culture Quantum Entanglement and Information First published Mon Aug 13, 2001; substantive revision Thu Aug 26, 2010 Quantum entanglement is a physical resource, like energy, associated with the peculiar nonclassical correlations that are possible between separated quantum systems. Entanglement can be measured, transformed, and purified. A pair of quantum systems in an entangled state can be used as a quantum information channel to perform computational and cryptographic tasks that are impossible for classical systems. 1. In 1935 and 1936, Schrödinger published a two-part article in the Proceedings of the Cambridge Philosophical Society in which he discussed and extended a remarkable argument by Einstein, Podolsky, and Rosen. It should not be supposed that Einstein's definition of a complete theory included the requirement that it be deterministic. In the original EPR article, two particles are prepared from a source in a certain quantum state and then move apart. He added (Schrödinger, 1935; p. 555): 2. 3. 4.

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.

Free eBooks at Planet eBook - 80+ Classic Novels and Literature Relativity Tutorial Galilean Relativity Relativity can be described using space-time diagrams. Contrary to popular opinion, Einstein did not invent relativity. Note the curved worldline above. Now it is still moving in its final state. Straight worldlines (unaccelerated particles) remain straight in this process. But Galilean transformations do not preserve velocity. Special Relativity But 200 years after Newton the theory of electromagnetism was developed into Maxwell's equations. Because the speed of light is special, space-time diagrams are often drawn in units of seconds and light-seconds, or years and light-years, so a unit slope [45 degree angle] corresponds to the speed of light. Thus in the situation shown in 3 space-time diagrams below, the central section shows the worldline of one stationary observer, one observer moving to the right, and two events on the future light cone on the event where the two observers' worldlines cross. What is the evidence for the invariance of the speed of light?

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. Furthermore we are shown how to respond with wit and panache to the technical mishaps that are part-and-parcel of the lecturer`s life.

Vulgata Clementina Epistola B. Joannis Apostoli Prima 11 Quod fuit ab initio, quod audivimus, quod vidimus oculis nostris, quod perspeximus, et manus nostræ contrectaverunt de verbo vitæ : 2 et vita manifestata est, et vidimus, et testamur, et annuntiamus vobis vitam æternam, quæ erat apud Patrem, et apparuit nobis : 3 quod vidimus et audivimus, annuntiamus vobis, ut et vos societatem habeatis nobiscum, et societas nostra sit cum Patre, et cum Filio ejus Jesu Christo. 4 Et hæc scribimus vobis ut gaudeatis, et gaudium vestrum sit plenum. 21 Filioli mei, hæc scribo vobis, ut non peccetis. 12 Scribo vobis, filioli, quoniam remittuntur vobis peccata propter nomen ejus. 13 Scribo vobis, patres, quoniam cognovistis eum, qui ab initio est. 28 Et nunc, filioli, manete in eo : ut cum apparuerit, habeamus fiduciam, et non confundamur ab eo in adventu ejus. 29 Si scitis quoniam justus est, scitote quoniam et omnis, qui facit justitiam, ex ipso natus est. 10 In hoc manifesti sunt filii Dei, et filii diaboli.

Physics 20b: Introduction to Cosmology - Spring 2010 - Download free content from UC Irvine Heavy Boots Editorial note: I received this as an email from a friend who got it from a friend who ... I do not know who the original author is, but I do believe this to be true. Who could possibly make it up? Heavy Boots About 6-7 years ago, I was in a philosophy class at the University of Wisconsin, Madison (good science/engineering school) and the teaching assistant was explaining Descartes. He was trying to show how things don't always happen the way we think they will and explained that, while a pen always falls when you drop it on Earth, it would just float away if you let go of it on the Moon. "No it wouldn't." the TA explained calmly, "because you're too far away from the Earth's gravity." I countered, "why didn't they float away?" "Because they were wearing heavy boots." he responded, as if this made perfect sense (remember, this is a Philosophy TA who's had plenty of logic classes). As we left the room, my friend Mark was raging. 1. About 47 percent got this question correct. 2. 13.
