Faster-than-light radio waves could revolutionize computer industries



Scientists have been plagued by Einstein’s theories which state nothing can travel faster than light. But over the past decade or so, we have seen a new branch of physics theorized, one which might give Einstein cause for pause. It’s called Superluminal Electromagnetic Field / Wave Propagation, which is basically a form of faster than light relativity. Experiments have been conducted by several scientists which involve light and radio sources traveling at speeds well in excess of the speed of light. Seem possible?

Earlier this year, a physicist called John Singleton created an application of this theory which he believes could greatly advance semiconductors.

Accelerated radio waves: A revolution in semiconductor industry?

Scientist John Singleton created an interesting device that accelerates the radio waves until they pass the speed of light. Yes, you've read that correctly - by using a process that is similar to the way Pulsar stars emit light - John jerked radio waves until they caved in and passed their theoretical speed barrier.
...
Singleton stated that usages for his device are enormous: "Because nobody's really thought about things that travel faster than light before, this is a wide-open technological field". This discovery could revolutionize medical, communication, semiconductor, space exploration fields.

Most people think Einstein said that nothing can travel faster than the speed of light, but that's not really the case, Singleton said.

Einstein predicted that particles and information can't travel faster than the speed of light — but phenomenon like radio waves? That's a different story, said Singleton, a Los Alamos National Laboratory Fellow.

Singleton has created a gadget that abuses radio waves so severely that they finally give in and travel faster than light.

"Because nobody's really thought about things that travel faster than light before, this is a wide-open technological field," Single ton said.

One possible use for the resulting speedy radio waves — which are packed into a very powerful wave the size of a pencil point — could be the creation of a new generation of cell phones that communicate directly to satellites, rather than transmitting through relay towers as they now do.

Scientists at UC San Diego's California Institute for Telecommunications and Information Technology (Calit2) have equipped a robot modeled after the famed theoretical physicist with specialized software that allows it to interact with humans in a relatively natural, conversational way. The so-called "Einstein Robot," which was designed by Hanson Robotics of Dallas, Texas, recognizes a number of human facial expressions and can respond accordingly, making it an unparalleled tool for understanding how both robots and humans perceive emotion, as well as a potential platform for teaching, entertainment, fine arts and even cognitive therapy.

Introducing the scarily realistic Einstein robot who can tell how you feel


With a big bushy moustache and a shock of white hair, scientists have modeled an ultra realistic robot on Albert Einstein. [...] Using specialised software the machine can recognise and respond to a number of human facial expressions in a natural way.

"In the short-term, Einstein is being used to develop computer vision so we can see how computers perceive facial expressions and develop hardware to visually react," says Javier Movellan, a research scientist in the Calit2-based UCSD Machine Perception Laboratory (MPL). "This robot is a scientific instrument that we hope will tell us something about human-robot interaction, but also human-to-human interaction.

"When a robot interacts in a way we feel is human, we can't help but react. Developing a robot like this one teaches us how sensitive we are to biological movement and facial expressions, and when we get it right, it's really astonishing."

[...]

Another important part of the robot's inner workings is its Character Engine Artificial Intelligence Control Software, which allows the programmer to author and define the persona of the character so it can hold a conversation.

"Einstein has pretty broad conversational abilities, although not like a human," Hanson notes. "In the demo mode, he might say something like, 'I'm an advanced perceptual robot bringing together many technologies into a whole that's greater than the sum of my parts, but here's what some of my parts can do. I can see your facial expressions and mimic them. I can see your age and gender. So why don't we demo some of these technologies?'"

Einstein Returns As A Robot




The robot can recognize and mimic 5,000 facial expressions and is powered by 31 motors and innovative new technology. The Einstein robot could be the next big thing in the world of engineering.

Javier Movellan, a professor at the college, says: "The best expressions that it can recognize right now are expressions of sadness and happiness."

Movellan adds, "You know that children with autism have problems recognizing facial expressions and producing facial expressions in social communication. So we're trying to see whether this robot will actually be useful and helpful to teach children with autism how to communicate with human beings."

Scientists hope to use the technology to improve the way computers relate to people.
