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:
How It Works: The Light-Driven Computer The speed of light is as fast as it gets, and IBM researchers are exploiting that fact to give supercomputers a boost. They've made the smallest-yet silicon chips that use light to transmit information. Most parts of the chip resemble those found on any other commercial chip. The parts that process or transform information—in other words, the parts that do the actual computing—still deploy electrons moving through semiconductor gates. One other benefit, says IBM engineer Will Green: The optical interconnects use significantly less power, making them cheaper to run. Click the image above to see inside IBM's optical microchip as it turns electrical pulses into light and back again.

10 Amazing Tricks to Play with your Brain 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. 10. At first this might sound like a bad practical joke. 9. In case you experience an injury, then see the injured part with an inverted binoculars, soon your pain will seem to be decreasing in its magnitude. Recently, a reasearch at Oxford University has lead to the discovery of a new pain killer – the inverted binoculars. Source: ( Link) 8. This requires two chairs and a blind fold. The Pinocchio effect is an illusion that ones nose is growing longer, as happened to the literary character, Pinocchio when he told a lie. 7. Source: ( Link) 6. Pages: 1 2
Homebrew CPU 7 Man-Made Substances that Laugh in the Face of Physics Odds are pretty good that some of you are reading this on an LCD screen while the rest of us are trying to make it out on the 13-inch monochrome monitor that came with our garage sale Commodore 64. But even with the LCD, some laptops still weigh over 10-pounds. And while that doesn't seem like much, the level of muscle atrophy experienced by the average Warcraft addict makes that weight a thousand times heavier. However, elastic conductors could fix that and make smuggling your porn collection into church even easier. Also, oooohhh. Elastic conductors are made of "ionic liquid" mixed with carbon nanotubes. What the Hell is it Used For? In addition to making screens that can be rolled up and stuck in our back pocket, a lot of scientists and doctors want to use elastic conductors to make flexible-lensed cameras... to be fitted to the back of the eyeball. A non-Newtonian liquid, in practical terms, is a liquid that turns solid when sufficient stress is applied. Also, something with lasers.

Aerospace Digital Library Technological singularity The technological singularity is the hypothesis that accelerating progress in technologies will cause a runaway effect wherein artificial intelligence will exceed human intellectual capacity and control, thus radically changing civilization in an event called the singularity.[1] Because the capabilities of such an intelligence may be impossible for a human to comprehend, the technological singularity is an occurrence beyond which events may become unpredictable, unfavorable, or even unfathomable.[2] The first use of the term "singularity" in this context was by mathematician John von Neumann. Proponents of the singularity typically postulate an "intelligence explosion",[5][6] where superintelligences design successive generations of increasingly powerful minds, that might occur very quickly and might not stop until the agent's cognitive abilities greatly surpass that of any human.

7 Apps for Teaching Children Coding Skills It's hard to imagine a single career that doesn't have a need for someone who can code. Everything that "just works" has some type of code that makes it run. Coding (a.k.a. programming) is all around us. That's why all the cool kids are coding . . . or should be. Programming is not just the province of pale twenty-somethings in skinny jeans, hunched over three monitors, swigging Red Bull. If you're concerned that that a) elementary school students don't have the ability to code, b) there's no room in the curriculum, and c) you don't possess coding chops to teach programming skills, throw out those worries. In no particular order, we have listed all the coding apps that are appropriate for young learners.
