How to automatically synchronize 5 or more metronomes - interesting video

So you thought you could march to the beat of a different drum So did these metronomes but subtly they all fell in step and joined the vast metronome army There is a social lesson here somewhere The man has five metronomes moving at the same speed, but not synchronized because he started them at different times Then he places them on a rolling surface Within a few seconds, they sync up [flash=640x480]http://wwwyoutubecom/v/Klw7L0OZbFQ[/flash] Now we have 9!

Cell Phone from the 1950's prediction - image

ON SOME night in the future a young man walking along Market Street in San Francisco may suddenly think of a friend in Rome Reaching into his pocket, he will pull out a watch-size disc with a set of buttons on one side He will punch ten times Turning the device over, he will hear his friend’s voice and see his face on a tiny screen, in color and 3-D At the same moment his friend in Rome will see and hear him The disc will be a telephone, a miniature model equipped for both audio and vid

Nokia release a 41 mega Pixel camera on a cellphone!

Now that's incredible The technology in the 808 PureView phone introduced on Monday was the result of Nokia engineers struggling over the fact that optically zoomed lenses just don’t work well in tiny spaces like phones “We had been working for a long time [on] optical zooms and had learned the hard way how difficult it is to achieve good performance in smartphones,” Nokia head of imaging technologies Juha Alakarhu said in an interview last week “Their structure is very complex and

Venus rotates once every 243 earth days and is slowing down

In the early 1990s scientists with NASA's Magellan mission calculated that a single rotation of Venus takes 243015 Earth days, based on the speed of surface features passing beneath the orbiting spacecraft But scientists now mapping Venus's surface with the European Space Agency's Venus Express orbiter were surprised to find the same features up to 124 miles 20 kilometers from where they were expected to be, based on the previous measurements According to the new data, Venus is r

A car door that totally rolls away out of sight - video

How about having a car door that totally disappears when you need to get in and out This one rotates down beneath that car floor leaving a huge hole that makes egress simple It seems a no brainer idea Why then after 5 years at least has no manufacturer taken it up Surely its not because of their crappy terribly designed website Looks like they invested millions in the product and hundreds in the website http://wwwdisappearing-car-doorcom/ [flash=640x480]http://wwwyoutubecom/v/A

Why do Adeles songs evoke so much emotion? Its called appoggiatura

On Sunday night, the British singer-songwriter Adele is expected to sweep the Grammys Three of her six nominations are for her rollicking hit "Rolling in the Deep" But it's her ballad "Someone Like You" that has risen to near-iconic status recently, due in large part to its uncanny power to elicit tears and chills from listeners The song is so famously sob-inducing that "Saturday Night Live" recently ran a skit in which a group of co-workers play the tune so they can all have a good

Welcome to the technological future - great video of coming technologies - video

Gorilla Glass manufacturer Corning has released a second video of their interpretation of the future of electronics and human integration Although I find the video fascinating, there is still the underlying emptiness of the technology Using the Wardrobe TV to pick your shoes Sure we can build it but what will it actually do apart from facebook updates That hole in society is a massive opportunity for programmers and developers [flash=640x360]http://wwwyoutubecom/v/X-GXO_urMow[/flash]

Growing old doesn't mean growing weak - image

Growing old doesn't mean that you have to lose your muscle mass, images from a study into aging show you can still maintain health through to old age Its disuse that weakens people not age itself Aging is commonly associated with a loss of muscle mass and strength, resulting in falls, functional decline, and the subjective feeling of weakness Exercise modulates the morbidities of muscle aging Most studies have examined muscle-loss changes in sedentary aging adults However this leav

Massive study shows Alternative medicine doesn't work

After a decade of research, and 25 billion dollars of taxpayer money, government funded research into so-called "alternative" medicine has little to show for it The government spent 25 billion dollars to determine that unpurified, poorly controlled drugs with generally low doses of active ingredients don’t work very well That treatments based upon unscientific notions don’t work, and that exercise and relaxation makes people feel better Oh - and they found that acupuncture doe

Russian Phobos-Grunt failure officially revealed as a programming screw up

So the dastardly Americans didn't fry the Russian Satellite with radar waves after all An official investigation revealed the most probable cause of the failure was a the lack of integrated testing Following the initial failure to initiate the flight sequence, the mission simply lacked any available scenario to communicate with the spacecraft in the low Earth orbit or to reboot its computers by a remote control The commission also established that the existing pre-programmed flight se

Program or be Programmed - the time has come to learn how to code

Historically literacy was a tool that few people needed to learn Church ministers were literate for their church services and teaching, and the illiterate people listened to what they said and learned the fundamentals of their belief system through music and song with hymns and prayers and poetry That's how the illiterate peasants were educated The movement to literacy and the movement to having a bible that ordinary people could read created social revolution, suddenly people could A s

Simple solution to water purification systems found with Graphine?

In a world where fresh water is growing scarce and purifying salt water to get it is expensive and power hungry, scientists may have invented a a simple way with Graphine to create fresh water without any fuss Imagine how important it would be to provide safe drinking water in the third world as well from unsafe water sources University of Manchester scientists have studied membranes from a chemical derivative of graphene called graphene oxide Graphene oxide is the same graphene sheet but

Robot Avatar brushes cat in virtual reality using a Kinect, Wii, HMD, Treadmill and NAO robot - video

Taylor Veltrop uses a Nao robot, a Kinect sensor bar, two Wii remotes, a head-mounted display, a treadmill and a calm cat to create a video with serious potential Imagine an upgraded version of this at the Fukushima nuclear power plant disaster Veltrop's robot walks up to a cat, grabs a brush, starts grooming then waves goodbye to its new feline friend as he leaves Save for an inadvertent bonk on the noggin, the cat seems to enjoy -- or at least tolerate -- the whole experience Veltrop

Levitating Star Wars racers on a quantum levitation track - ultimate toy - video

Gas up your Star Wars racer with liquid nitrogen, and put them on the track and race 'em! Here is a short footage on our recent work on quantum levitation We were inspired by the game Wipe'out to do our work With this new technology, we hope to revolutionize the world of motor transport; Maybe in a near future we could assist to a real Wipe'out race [flash=640x360]http://wwwyoutubecom/v/Zqmdv5iyIOY[/flash]
