3D technology that'll change the Science View

Upcoming 3D technology to make science fiction a reality

       

Science fiction till now was a part of films, but with upcoming 3D technology, it will become as palpable as the reality that surrounds you. You can take a ride in to a human brain, universe or ocean and more, just by wearing 3D Glasses. Thanks to the Computer scientists at the University of Illinois at Chicago, who are pushing science fiction closer to reality with a wraparound virtual world.

This technology is known as CAVE2, where a screen encircles the viewer 320 degrees. A panorama of images springs from 72 stereoscopic liquid crystal display panels, gives you a strong sense of being able to touch them.

Scientist in many fields are striving to truly understand overwhelming amount of data. Jason Leigh, co-inventor of the CAVE2 virtual reality system, believes this technology answers that challenge.

"To do science in this kind of environment is absolutely amazing."

Type in Air for a Computer...!!!

Writing Without Keyboard: Handwriting Recognition On the Wrist

Typing text messages on the mobile phone via the tiny soft keyboard is very cumbersome. How about simply writing it into the air! This idea drove the development of "airwriting" made by computer scientists of Karlsruhe Institute of Technology (KIT). Sensors attached to a glove record hand movements, a computer system captures relevant signals and translates them into text.

The system offers a new interface for wearable computing applications. These are computer systems worn like clothes, which can be integrated seamlessly into the everyday life of the user. "Information technology is used any time and anywhere, but smart phones are still working on the basis of virtual keyboards and small screens. However, gestures allow for new types of input -- in particular for mobile devices or devices integrated in clothing. The interaction is embedded seamlessly in everyday life".

"The airwriting glove is used to write letters into air, as if using an invisible board or pad."
For this purpose, acceleration sensors and gyroscopes are attached to the thin glove. Contrary to systems based on cameras, these sensors are very small, mobile, and robust. They record the movements of the hand and transmit them to a computer system via a wireless connection. The computer system first checks whether the user is indeed writing.

Quora is a question-and-answer website created, edited and organized by its community of users.

Quora had an estimated 500,000 registered users, as of January 2011. In June 2011, Quora redesigned its website, in order to make information discovery and navigation easier. Some noted that the redesigned site had definite similarities to Wikipedia. Quora released an official iPhone app on September 29, 2011  and an official Android app on September 5, 2012.
In September 2012, co-founder Charlie Cheever announced that he was stepping back from a day-to-day role at the company, while continuing to retain an advisory role.
In January 2013, Quora launched a blogging platform.

Quora requires users to register with their real names rather than a screen name. Quora users may also link/ log-in with their Quora accounts with their Twitter and Facebook accounts. Quora users can upvote or downvote answers. They can also suggest edits to existing answers provided by other users. The Quora community includes some well-known people, such as Steve Case, Marc Andreesen, Dustin Moskovitz, Jimmy Wales, Justin Trudeau and Ashton Kutcher The largest group of Quora users is located in Silicon Valley, followed by New York City. 

Quora uses Pylons and Comet for its backend and Ubuntu Linux as its operating system with MySQL as its database. It also uses Git and memcached. Quora uses Nginx as a reverse proxy server and HAProxy for load balancing.Quora has developed its own algorithm for ranking answers, which works similar to PageRank.Quora uses Amazon Elastic Compute Cloud technology to host the servers that run its website. In August 2011, Quora switched its infrastructure's Python implementation from CPython to PyPy, in order to improve response time.

By default, Quora exposes its users' profiles, including their personal names, to search engines.

Nano Technology

Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic and molecular scale. Generally, nanotechnology works with materials, devices, and other structures with at least one dimension sized from 1 to 100 nanometres.

Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc.

Scientists currently debate the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.
