Beyond MegaPixels – Its Femto-Photography!!!

Femto-photography is a term describing ultra high speed imaging. Femto-photography of macroscopic objects was first done by a team at the MIT Media Lab lead by Ramesh Raskar. Before that the term has at least been used for certain proposed experimental procedures in experimental nuclear physics.

In their publications Raskar’s team claims to be able to capture exposures so short that light only traverses 0.6 mm (Equal to only a few picoseconds, or thousands of femtoseconds) during one exposure by combining available high end research equipment and sophisticated sampling algorithms. Raskar presented his team’s feat during TEDGlobal 2012, reaching a wider audience through viral video.

ISRO awaits for Historic 100th mission

The Indian Space Research Organisation is prepared for its 100th mission on 9th September 2012 with the commercial launch of two foreign satellites from the spaceport of Sriharikota in Andhra Pradesh.

ISRO plans to launch 720-kg SPOT-6 remote sensing satellite from France (built by ASTRIUM SAS) and a 15-kg Japanese spacecraft Protiers on board the home-grown Polar Satellite Launch Vehicle (PSLV-C21) tomorrow, in a major milestone of sorts.

19 year old student invents a new propulsion system

An Egyptian physics student has successfully created a new propulsion device that could accelerate space probes and artificial satellites through quantum physics and chemical reactions instead of the current radioactive-based jets and ordinary rocket engines. Mustafa’s propelling device is based upon a scientific mix between quantum physics, space technology, chemical reactions and electrical sciences. Current space probes, artificial satellites, spacecrafts and space vehicles use rocket gas engines that depend on forcing a gas to the outside of the vehicle at a supersonic speed or the chemical reactions rockets which propel by solid or liquid fuels such as radionuclide or petroleum, or the electrically-propelled probes which depend on thrusting force via accelerating ions.

Cotton – Fabric of our lights

The advancement of electronics in textiles field has reached a new level. Earlier electronics were embedded in the textiles,which provides a wide variety of applications such as monitor homes for noxious chemicals, help firefighters maneuver in smoky buildings, help stroke victims recover their function and much more. With increase in the applications e-textiles become much bulkier, with full of wires  and sensors,thus not suitable for mass production. Hence scientists moved a step forward  and were  successful in  making the fabric itself as electronic  device.

Parallel Universes

Some of the world’s leading physicists believe they have found startling new evidence showing the existence of universes other than our own. One possibility is that the universe is so vast that an exact replica of our Solar System, our planet and ourselves exists many times over. In 1954, a young Princeton University doctoral candidate named Hugh Everett III came up with a radical idea: That there exist parallel universes, exactly like our ­universe

REWOD

With the development of portable electronic devices there is a huge demand for electrical batteries. High-power mechanical energy harvesting can potentially provide a valuable alternative to the use of batteries, but, until now, a suitable mechanical-to-electrical energy conversion technology did not exist.

The world’s smallest magnetic data storage unit is made of just 12 atoms, squeezing an entire byte into just 96 atoms, a significant shrinkage in the world of information storage. It’s not a quantum computer, but it’s a computer storage unit at the quantum scale. By contrast, modern hard disk drives use about a million atoms to store a single bit, and a half billion atoms per byte.
