The God Particle

The God Particle By C.R. Manmadhan Digital image on canvas, 68x91 cm, 2012 Amid living matter and endless space, C.R. Manmadhan Juxtaposes Shiva and Parvati with a contrasting red spot that represents the enigmatic "god particle" of physics, after which this work is titled. Based in Kochi, Manmadhan, 65, took to art seriously after he retired in 2006 as News Editor of Mathrubhumi, the Malayalam daily. He says that his works, whether acrylics or digital, draw from all his resources, including his training as a journalist and his master's degree in zoology. Manmadhan recently held third solo exhibition at David Hall, Fort Kochi.

Waterproof your device

Lots of cellphones die from drowning (raise your hand if you've dropped yours in a puddle, washing machine or the toilet). In the past, if you wanted to waterproof your phone, you had to buy a special plastic case or pray that the rice trick would revive it (see How to save a soggy phone, below). But solution may be at hand. Tech research company Liquipel (see ) has invented a new technique that covers devices, inside and out, in a razor thin, nearly invisible waterproof shell. When water hits the device, it beads up and rolls off, leaving the phone or tablet dry. In a test, popular Science editors sent an iPhone 3GS to Liquipel for waterproofing. When they got the phone back a few days later, they turned it on and ran it under a tap for five minutes. The phone operated normally while under the faucet. Afterwards, the touch screen was slow to respond at first, probably because of water droplets on the screen that hadn't yet rolled off, but after few seconds, the p

Improve your Eyesight with an App

Hate reading glasses? A new app called Glasses Off might let you drop them by training your brain to better interpret that fuzzy print in the newspaper. Users play quick games that employ special wavy images to stimulate connections in the visual part of the brain. In a recent small study, people could read paper without reading glasses after three months of training (15 minutes three times a week), and their reading speed increased by 17 words per minute. The developers plan to launch the app for iPhones and iPads by early 2013, followed by an Android version. Calculate your Heart Rate with your face Cardiio , a new app for iPhone and iPad developed by Harvard and MIT researchers, can calculate heart rate by merely gazing at your face. It uses your device's camera to measure tiny changes in blood flow in your face that occur when your heart beats. Simply line up your image with the displayed target, and the app reports your heart rate in seconds; when use in a well lit environmen


Volcanoes can change the course of history. On 24 August 79 Ad the Roman towns of Pompeii and Herculaneum were laid waste by eruption of Mount Vesuvius, which cost many thousands of lives. In April 1815, Indonesia's Mount Tambora erupted with such force, fine particles floated into the northern hemisphere by the next year and caused "the year without a summer" in parts of North America and Europe, leading to crop failure and starvation. On 27 August 1883 the Indonesian volcano Krakatoa literally blew its top, causing the deaths of around 36,000 people. And the threat to human life from these types of events happening in the future remains the same. That's because there's no way of preventing volcanic eruptions. The forces lying dormant in the earth are too powerful. The only way of protecting people is to evacuate them in time. Luckily, most eruptions give us some degree of advanced warning. "The heat is on. Beautiful and terrible in equal measure -- volcanic

4D printer : Printing self-assembling 3d object!

Everybody knows about 3d printer and of-course it becomes handy tool for innovators ,Students ,Engineers and for designers. 3d printer can build any object in three dimensions , by just slicing it in to possible no. of 2D layers.That is why 3d printing is called additive manufacturing process ,because in this process we are adding material rather than cutting or shaping. imagine if your printer has ability to print the 3D object as well as assemble it self! Introduction of 4D Printer ARC Center of Excellence for Electromaterials Science (ACES) , the University of Wollongong (UOW) ,MIT researchers,Self-Assembly Lab, Stratasys and Autodesk working on new concept of 4D printer. 4D printing is technology that print multi-material object and produce any mechanism that will transform 1D to 3D shape,2D to 3D shape or morph from one 3D shape into another by using heat, water, light or any other energy input.this technique offers adaptability and dynamic response for structures and sy

An Automatic machine | was developed in 1860

James Nasmyth was the last of the great man of the Industrial Revolution. In future, as the machines themselves become more and more complicated, developments of machines would be made by many companies rather than by individual man. Much of this work took place in America, probably because there were not so many skilled men available for work as in Britain, so machines had to take the place of man. The american firm of Brown and Sharpe was one of the leaders. The specially shaped milling cutter was one of their development. Just a whitworth had the idea of standard  nut and bolts, so Brown and Sharpe brought in this idea of standard thickness of wire and sheet metal. They also developed new types of grinding machines. The firm was also famous for the milling machine. It was called a universal machine because the clever design of the work holder made it possible to cut metal at any angle. The knee carrying the work table, with up and down adjustment, was also great improvement. It

Machine Tools | 1800-1880

By the time of  James Nasmyth's retirement in 1852 , all the basic type of machine tool in use today had been invited -lathes shaping and planning machines, milling machines and grinders . Source The illustration shows how each of this is used to shape a piece of metal. A lot has been said already about the lathe, since this was developed first. The lathe shown was mad in about 1880 . It was four pulley wheels of different sizes, to very the speed of work piece, which is driven by the head and supported at the other end by the tail stock . The slid which hold the cutting tool can be move along the bed by hand or by means of leadscrew .It can be moved at right angle to the bed by hand. The back gear enable the speed of the leadscrew to be altered so that different types of screw threads can be cut. The first planning machine was mad by Richard Roberts, who mad worked for Maudslay, in 1817 .  The one shown, made in 1884, is very little different from one produced by Wh

Life in the factories

In 1750,there were no factories: people worked at home, or in little workshops employing just a few people. One hundred years later, everything had changed, ans millions were working in factories. During this period the number of people living in Manchester increased by 20 times, and in Birmingham and Glasgow by nearly as much. The factories were noisy, dirty, dangerous, and life was very hard for the factory workers. Men, women and children had to to work for up to 18 hours a day,and many accidents occurred because people were so tired. It wasn't until 1817 that parliament passed  a law limiting the working day to 10 hours for women and children. Source Children usually started work at the age of nine, and were harshly punished for not paying not attention to their work even for looking out of the window. It was not just  a few unlucky children either. In many factories at this time at least half the workers were children, and at least half of the grown-ups were women;

One another largest star found in universe

HR 5171A We only know of 14 such stars in our galaxy, and they’re likely a brief phase that huge stars pass through during their lifetimes. And HR 5171A ( here’s its stats , for you observationists out there) is particularly hypergigantic. As an upcoming paper in Astronomy & Astrophysics details, the star is about 1300 times as wide as the Sun, or around 12 times the average Earth-sun distance. That’s big enough to put it among the top ten largest stars we know about. It’s also about a million times brighter than our sun. HR 5171A lies about 12,000 light-years away, in the constellation of Centaurus, but it’s bright enough that you could still spot it with the naked eye under ideal conditions.Read more

Digital Image Processing-Simplified.

Digital image processing is a very interesting area of science. However, unlike many other areas of computer science, this branch of science very firmly based on its applicability, which it therefore makes them interesting., in practice we encounter a number of problems which we would like to solve. Whether the automated security guards, or simplified processing rentgenovyh images, in almost every area of practice in a certain manner can deploy equipment: digital image processing and not generally corresponding means of computer vision. It is therefore possible to design software solutions that bring its users - new features (for example, automated surveillance of multiple objects at once using a system of wi-fi camera and special software solution) - optimize existing activities (eg automatic search of Vashti defective products) - reduces the cost human resources and thus exhibit a high return on investment. It is obvious that this whole area is very interesting not only from a scien

build your own robot? you must know this little thing of Robotic Technology.

Public fascination with robots goes back a long way, and it was only a matter of time before people decided it would be a fun hobby to build them at home. Take this quiz to learn a bit about the parts involved in building your own robot! Which components are used in a home-brewed robot? 1.frame 2.motors. 3.electronics. All of those components will be found in a home-built robot. The frame is the base of the design, to which everything else will be attached; motors will run things like wheels and arms; and electronics will provide the brains and juice to keep the robot working. How much does it cost to build your own robot? If it's your first robot, you should anticipate spending about $100 to $400. While experienced robot builders could build one for very little money, that's only because they are experienced and also have likely built up a supply of parts over the years. What is the simplest control method for a robot? Differential drive is a way that a robot can

Three-phase electric power.

Three-phase is a common method of electric power transmission.It is a type of polyphase system used to power motors and many other devices. Three phase has properties that make it very desirable in electric power systems. Firstly the phase currents tend to cancel one another (summing to zero in the case of a linear balanced load). This makes it possible to eliminate the neutral conductor on some lines. Secondly power transfer into a linear balanced load is constant, which helps to reduce generator and motor vibrations. Finally, three-phase systems can produce a magnetic field that rotates in a specified direction, which simplifies the design of electric motors. Three is the lowest phase order to exhibit all of these properties.

Integrated circuit.

A monolithic integrated circuit (IC) or often referred to as a microchip or simply chip is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) which has been manufactured in the surface of a thin substrate of semiconductor material. Circuit design. The process of circuit design can cover systems ranging from national power grids all the way down to the individual transistors within an integrated circuit.For simple circuits the design process can often be done by one person without needing a planed or structured design process, but for more complex designs, teams of designers following a systematic approach with intelligently guided computer simulation are becoming increasingly common. As circuit design is the process of working out the physical form that an electronic circuit will take, the result of the circuit design process is the instructions on how to construct the physical electronic circuit. This will normally take the f


Seismometer are used by seismologists to measure and record seismic waves. By studying seismic waves, geologists can map the interior of the Earth, and measure and locate earthquakes and other ground motions. The term seismograph is usually interchangeable, but seismometer seems to be a more common usage. Seismic wave. A seismic wave is a wave that travels through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion.There are two types of seismic wave, namely, 'body wave' and 'surface wave'. There are two kinds of body waves: primary (P-waves) and secondary (S-waves). Surface waves are analogous to water waves and travel just under the Earth's surface. They travel more slowly than body waves.

As circuit design is the process of working out the physical form that an electronic circuit will take, the result of the circuit design process is the instructions on how to construct the physical electronic circuit. This will normally take the form of blueprints describing the size, shape, connectors, etc in use, and artwork or CAM file for manufacturing a printed circuit board or Integrated circuit.

Aspect-oriented programming.

In software engineering, the programming paradigm of aspect-oriented programming (AOP), also called aspect-oriented software development (AOSD), attempts to aid programmers in the separation of concerns, or the breaking down of a program into distinct parts that overlap in functionality as little as possible. Hash function. A hash function or hash algorithm is a function for examining the input data and producing an output hash value.The process of computing such a value is known as hashing. Object-oriented programming. In computer science, object-oriented programming, OOP for short, is a computer programming paradigm.The idea behind object-oriented programming is that a computer program may be seen as composed of a collection of individual units, or objects, that act on each other, as opposed to a traditional view in which a program may be seen as a collection of functions or procedures, or simply as a list of instructions to the computer.

Best of Both Worlds: Towards a Quantum Internet With Combined Optical and Electrical Technique.

An Australian team led by researchers at the University of New South Wales has achieved a breakthrough in quantum science that brings the prospect of a network of ultra-powerful quantum computers -- connected via a quantum internet -closer to reality.The team is the first in the world to have detected the spin, or quantum state, of a single atom using a combined optical and electrical approach. The study is a collaboration between researchers from the ARC Centre of Excellence for Quantum Computation and Communication Technology based at UNSW, the Australian National University and the University of Melbourne. It is published in the journal Nature. UNSW's Professor Sven Rogge said the technical feat was achieved with a single atom of erbium -- a rare earth element commonly used in communications -- embedded in silicon. "We have the best of both worlds with our combination of an electrical and optical system. This is a revolutionary new technique, and people had doubts it w

Computer Algorithms Help Find Cancer Connections.

Powerful data-sifting algorithms developed by computer scientists at Brown University are helping to untangle the profoundly complex genetics of cancer.In a study reported today in the New England Journal of Medicine, researchers from Washington University in St. Louis used two algorithms developed at Brown to assemble the most complete genetic profile yet of acute myeloid leukemia (AML), an aggressive form of blood cancer. The researchers hope the work will lead to new AML treatments based on the genetics of each patient's disease. The algorithms, developed by Ben Raphael, Eli Upfal, and Fabio Vandin from the Department of Computer Science and the Center for Computational Molecular Biology (CCMB), played a key role in making sense of the giant datasets required for the study. The work was part of The Cancer Genome Atlas project, which aims to catalog the genetic mutations that cause cells to become cancerous. Doing that requires sequencing the entire genome of cancer cells and
