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:

10 Amazing Tricks to Play with your Brain / Mind Mind is the aspect of intellect and consciousness experienced as combinations of thought, perception, memory, emotion, will and imagination, including all unconscious cognitive processes. Mind manifests itself subjectively as a stream of consciousness. Neuroanatomists usually consider the brain to be the pivotal unit of what we refer to as mind. The Human Brain tricks us whenever it can. You don’t actually see what it is in real or you don’t even actually hear or smell the way it should be.

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. The First Zombie-Proof House Somehow, ritual drunk-conversation concerning team captains for the apocalypse has become a major part of the lives of 20-somethings. Having been matured in the Grandaddy-crowned masterpiece film (put “A.M. 180” on and forget that you have a job) 28 Days Later and the best-selling Zombie Survival Guide, we’re all a little too ready to deal with the 2012 zombie apocalypse of our dreams. “The Safe House,” designed by KWK Promes, starts to get eerily close to something I could work with, if say 200 bludgeoned members of the undead army came over to eat their way into borrowing some sugar. “The most essential item for our clients was acquiring the feeling of maximum security,” begins the designers’ website in the summary of the structure.

Story of Bottled Water The Story of Bottled Water, released on March 22, 2010 (World Water Day), employs the Story of Stuff style to tell the story of manufactured demand—how you get Americans to buy more than half a billion bottles of water every week when it already flows virtually free from the tap. Over five minutes, the film explores the bottled water industry’s attacks on tap water and its use of seductive, environmental-themed advertising to cover up the mountains of plastic waste it produces. The film concludes with a call for viewers to make a personal commitment to avoid bottled water and support public investment in clean, available tap water for all. Credits

Molecular secrets of the "iron-plated snail" February 03, 2010 Molecular secrets of the “iron-plated snail” Life isn’t easy for the “scaly-foot gastropod”. 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.

How to win Rock-paper-scissors every time I admit it. When I first heard there are actual tournaments for Rock-paper-scissors, sanctioned by the World Rock Paper Scissors Society, I laughed. I mean seriously, $50k to the winner of a game that requires no skill whatsoever? Absurd. Boy was I wrong. Boy discovers microbe that eats plastic It's not your average science fair when the 16-year-old winner manages to solve a global waste crisis. But such was the case at last May's Canada-Wide Science Fair in Ottawa, Ontario, where Daniel Burd, a high school student at Waterloo Collegiate Institute, presented his research on microorganisms that can rapidly biodegrade plastic. Daniel had a thought it seems even the most esteemed PhDs hadn't considered. Plastic, one of the most indestructible of manufactured materials, does in fact eventually decompose. It takes 1,000 years but decompose it does, which means there must be microorganisms out there to do the decomposing.

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.

Amazing Sight in the South Pacific A yacht was traveling in the south Pacific when the crew came across a weird sight. Look at these photos and try to imagine the thrill of experiencing this phenomenon. NO!!!! Robert Lanza, M.D.: Does the Past Exist Yet? Evidence Suggests Your Past Isn't Set in Stone Recent discoveries require us to rethink our understanding of history. "The histories of the universe," said renowned physicist Stephen Hawking "depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history." Is it possible we live and die in a world of illusions? Physics tells us that objects exist in a suspended state until observed, when they collapse in to just one outcome. Paradoxically, whether events happened in the past may not be determined until sometime in your future -- and may even depend on actions that you haven't taken yet.
