Oldest Mayan Calendar Has NO Hint of World End

Oldest Mayan Calendar Has NO Hint of World EndResearchers say new analysis of the earliest known Mayan calendar, found in an ancient house in Guatemala, offers no hint that the world’s end is imminent. The painted room in the residential complex at the Mayan archaeological site of Xultun is believed to have been where the town scribe kept records, writing computations on the walls in an effort to find “harmony between sky events and sacred rituals,” researchers say in the journal Science.

The hieroglyphs date back to the ninth century AD, making them hundreds of years older than the calendars in the Maya Codices, which were recorded in bark-paper books from 1300 to 1521. Boston University archaeologist William Saturno says the discovery appears to be the 365-day solar calendar, the 584-day cycle of Venus, and the 780-day cycle of Mars :: Read the full article »»»»

Light Disorder: Laws of Reflection, Refraction and the Surface Pattern Loophole

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 »»»»

Solar Dynamics Observatory

The satellites and space craft that we launch to observe our world are our eyes and ears in space. Advances in satellites pointed at the Sun have been enormous over the last decade. The latest satellite gathering solar information is NASA’s SDO. Chances are you have seen footage produced by this high-tech observer, all of the solar flare footage used by media channels lately have been thanks to NASA’s SDO satellite. The quality of the footage is incredible, only matched by the sheer amount of information this satellite is sending back to earth, over a terabyte of data a day. The data that this satellite collects will help us understand what drives our most important neighbour, the Sun.

After SDO’s first year of operation NASA released a compilation of jaw dropping footage of the sun. ‘First Light’  was the original footage released by NASA, this footage was mixed down –edited– into the punchy little two-minute ‘Haunting Images from the Sun’ by SpaceRip, infamous science documentary re-releaser on YouTube. SDO has since produced even more spectacular footage – see video below ‘Sun Sends Out X6.9 Class Solar Flare’, the monster flare occurred August 9, 2011.

Assembled at the Goddard Space Flight Centre in Maryland and launched February 11, 2010 from Cape Canaveral SDO was initially placed in low Earth orbit. Eventually it will slowly be maneuvered into it’s final circular geosynchronous orbit –stays facing the sun while the Earth turns– at an altitude of 36,000 km, giving SDO a permanent view of the Sun. The data collected by SDO is part of the ‘Living with a Star’ program which aims to understand the sun and it’s influence on the Earth, the Earth-Sun relationship.

Building on the technology of the previous solar observing satellite SOHO, SDO improves on SOHO‘s instruments and adds new sensors to the study of the sun. Three  instrument suites are onboard for observing; Extreme Ultraviolet Variability Experiment (EVE) , Helioseismic and Magnetic Imager (HMI) and Atmospheric Imaging Assembly (AIA) making SDO the most advanced solar observatory ever. These three sets of sensors are each recording a different perspective of the sun in real-time, HMI listens to the Suns magnetic fields while EVE and AIA watch and photograph the Sun’s outer layers. The sensors collect and send back over a Terabyte of data per day. Once the data is received at the Goddard flight control centre it’s stored and served up to various research facilities. Individually each of the sensors produces spectacular images, together they are stunning. Read the full article »»»»

i2R E-Paper

Posted: August 10th, 2011 | Author: | Filed under: Applied Science, Cankler | Tags: , , , , , , , , | Comments Off on i2R E-Paper

As display technologies evolve display panels are finding their way into many new places, this is about to accelerate. R&D scientists from Taiwan have demonstrated a new display technology that completely cuts the cord, the i2R e-paper has no plug. A display that doesn’t have a clue what electricity is. The flexible panel uses heat instead of electricity to erase and write images to the display. Created in the R&D labs at Taiwan’s Industrial Technology Research Institute – ITRI – this may be the technology that allows displays to be everywhere. The i2R e-Paper is already winning awards for ITRI, having once again won a place on the R&D 100 Awards, the Oscars of invention.

“This year ITRI was again honored with the R&D 100 Awards for its rewritable electronic paper i2R e-Paper. This is a special green energy conserving display technology.” John Chen, general director of ITRI’s Display Technology Center

By using existing manufacturing technologies, thin-film plastic rolls, combined with the incredibly simplified design ITRI has kept the costs of i2R e-paper low, estimates suggest each finished sheet of e-paper can be produced for as little as $1.50 per sheet. Even compared to tradition electric e-paper -as found in the Kindle- this is incredibly cheap. Removing the electrical requirements simplified the display immensely, no wires or circuits, no electronics to control the display all keeping the costs down. With the display being so simplified an external thermal writing device is required to do what the chips would have done, write and erase images on the display. The writer is extremely low power which should make portable writers possible. Read the full article »»»»

Stretchy Rubber OLED Display

Posted: August 10th, 2011 | Author: | Filed under: Cankler, Physics Applied, Science | Tags: , , , , , , | Comments Off on Stretchy Rubber OLED Display

Are we on the brink of a major technology shift, display and electronics technology is shifting from metallic wires to plastic -polymer electronics- with surprising results. Research scientist  at UCLA Henry Samueli School of Engineering and Applied Science  have demonstrated an amazing form of OLED display material that can be stretched upto 45%. Not quite ready to be rolled up into a ball and bounced around the room this hardy little stretchy display is a breakthrough on the road to fully plastic electronics built into everything clothing to coffee tins.

The OLED display demonstrated by the researches was able to be twisted and stretched then return to its original shape all while still operating unaffected. A number of breakthroughs were made in producing this stretchy little patch of plastic. The use of carbon nanotubes in the polymer electronics gives the display flexibility and negates the need for metallic wiring. The polymer also acts as a framework for the carbon nanotubes to form around, simplifying the manufacturing allowing roll to roll manufacturing. The display -emissive polymer- layer is sandwiched between two electronics -composite electrode- layers. The emissive polymer layer contains a discrete LED chip interconnected with stretchable electrodes giving the displays internals enough flexibility to remain fully functional even when stretched. The two outer composite electrode layers contain the single-walled carbon nanotube polymer composite electrodes. These outer layers are also responsible for returning the display to its permanent shape, this effect is due to the shape-memory properties of the composite electrodes. Read the full article »»»»
