Outwardly it may seem that two vocations couldn’t be further apart. Throughout my life I’ve known a heap of really smart people, people with really high IQ’s that excelled in school, that went on to become intellectually impressive. I’ve also met and worked with a lot of extremely successful entrepreneurs. Entrepreneurs worth 7, 8 and even 9 figures. Intriguingly, the two groups are pretty much mutually exclusive. With one exception, SCIENTISTS. Why? :: Read the full article »»»»
Scientists at Harvard have discovered new ways of making light dance, along the way changing the laws of reflection and refraction of light. The wonderful world of Nano particles, along with their effects on light’s behaviour were explored in order to make these discoveries. Under normal circumstances light is nice and predictable, Mr Consistent, the team from the Harvard School of Engineering and Applied Sciences – SEAS – found a loop-hole though, precise patterns of metallic nanostructures. Just as in a Carnivals Magic Mirror amusement the nanostructures were able to warp and bend light, unlike the carnival though they did not require bendy mirrors or clever lighting. Instead using Nano structures embedded in precise patterns on the surface of silicon they were able to alter lights behaviour. Their findings were published in the scientific journal Science, September 2 and have since led to the reformation of the mathematical laws of reflection and refraction, the predicted path of a ray of light bouncing of a surface or passing from medium to medium, bouncing or bending:: Read the full article »»»»
Optical fiber cable wiggles it’s way between continents, beneath oceans, under streets, hundreds of thousand of kilometers of the acrylate polymer or polyimide clad silica cable, allowing for almost loss-less communication. With less data loss and higher bandwidth, optical-fiber technology allows information to freely bound about the the globe, bringing pictures, video, and other data from every corner of the globe to your computer in a split second. Although optical-fibers and their clever photonic relay of information are increasingly replacing copper wire and it’s inefficient electron based data processing in the communication world, today’s computer technology still relies entirely on electron based – CPU -micro-processing.

Imagine getting caught in a thunderstorm that’s 8 times wider than Earth, with discharges of lightning 10,000 times more powerful than normal, flashing 10 times per second at its peak. Now imagine that this storm is just getting warmed up. One of the most violent weather events we’ve ever witnessed in the Solar System began to erupt on Saturn last December and is still enthralling astronomers, the British journal Nature reports. According to Nature, Lightning discharges in Saturn’s atmosphere emit radio waves with intensities about 10,000 times stronger than those of their terrestrial counterparts. These radio waves are the characteristic features of lightning from thunderstorms on Saturn, which last for days to months. Convective storms about 2,000 kilometres in size have been observed in recent years at planetocentric latitude 35° south (corresponding to a planetographic latitude of 41° south). Here we report observations of a giant thunderstorm at planetocentric latitude 35° north that reached a latitudinal extension of 10,000 kilometres—comparable in size to a ‘Great White Spot about three weeks after it started in early December 2010. The visible plume consists of high-altitude clouds that overshoot the outermost ammonia cloud layer owing to strong vertical convection, as is typical for thunderstorms. The flash rates of this storm are about an order of magnitude higher than previous ones, and peak rates larger than ten per second were recorded. This main storm developed an elongated eastward tail with additional but weaker storm cells that wrapped around the whole planet by February 2011. Unlike storms on Earth, the total power of this storm is comparable to Saturn’s total emitted power. The appearance of such storms in the northern hemisphere could be related to the change of seasons, given that Saturn experienced vernal equinox in August 2009. Read the full article »»»»
Researchers at Georgia Institute of Technology have demonstrated – at the IEEE conference July 6 – technology capable of harnessing ambient electromagnetic energy that pervades our modern world. By taking advantage of the transmitters that are already covering modern cities power is extracted from thin air. In a sense turning mobile phone base stations, tv transmitters and radio station transmitters into micro power stations. While this technology only provides very small amounts of power it is enough to power simple sensors and devices, eventually as the technology develops more advanced electronics may be powered, we may eventually see self-powered bumper stickers telling us to back the f off.
“There is a large amount of electromagnetic energy all around us, but nobody has been able to tap into it,” said Manos Tentzeris, a professor in the Georgia Tech School of Electrical and Computer Engineering who is leading the research. “We are using an ultra-wideband antenna that lets us exploit a variety of signals in different frequency ranges, giving us greatly increased power-gathering capability.” Read the full article »»»»
