## Clean Technology – Why it is the time to be Green?

What is the 'Need' of the, "Clean Technology"? Why Not? There is a desperate need to meet the challenges caused by climate change and environmental degradation. In the past, it was the entrepreneurial spirit that contributed most to the innovations with far-reaching benefits. Besides, scientists from outside the industry innovated technologies like steam power, the railways, telegraph, radios and telephone, petroleum, the automobile, computer, internet etc. Yet the role of entrepreneurial innovation in addressing environmental problems has received relatively little…

## Touch Screen Systems

A typical touchscreen input system is basically an input device like a mouse or trackpad. If counting as a definition, a touch screen is a computer display screen that is sensitive to human touch, allowing a user to interact with the computer by touching pictures or words on the screen. How? A touchscreen system is made up of a touch sensor, a controller card, and a software driver. WHAT ARE TOUCHSCREENS USED FOR? Touch screens are used with information kiosks,…

## Elementary Particle Physics

Particle physics is the study of Particles, from what everything is made of. In this section of physics we study the fundamental particles that make up all of matter, and their mutual interaction. Everything around us is made up of these particles, you may say, made up of fundamental building blocks of nature. So, what are these building blocks? In the early nineteenth century, it was believed that atoms were fundamental; they were thought to be the smallest part of…

## Introduction to the Universe

Stars Universe is vast and amazing. There are many millions of trillions of stars in the sky, most of them being bigger than our sun. Stars account for 98% of the matter in a galaxy. The rest of 2% consists of interstellar or galactic gas & dust in a very attenuated form. The normal density of interstellar gas throughout the galaxy is about one tenth of a hydrogen atom per cm³ volume. Stars tend to form groups. Major types of…

## Top 5 Chemists Killed or Injured by their Experiments

Karl Scheele Died while testing his discoveries Scheele was a brilliant pharmaceutical chemist who discovered many chemical elements-Oxygen, Molybdenum, Tungsten, Manganese and Chlorine. He also discovered a process very similar to pasteurization. Scheele had the habit of taste testing his discoveries and, fortunately, managed to survive his taste-test of hydrogen cyanide HCN. But alas, his luck was to run out: he died of symptoms strongly resembling mercury poisoning.   Robert Bunsen Blinded himself in one eye Robert Bunsen is probably…

## What is Real Analysis?

Real analysis is the branch of Mathematics in which we study the development on the set of real numbers. We reach on real numbers through a series of successive extensions and generalizations starting from the natural numbers. In fact, starting from the set of natural numbers we pass on successively to the set of integers, the set of rational numbers and that of real numbers. Let $\mathbf {Q}$ be the set of rational numbers. It is well known that…

## Entropy and Disorder

In science, we look for patterns to discover nature's laws. What is the pattern common to all spontaneous changes? To find a pattern, it is often best to start with very simple examples, because then the pattern is likely to be more obvious. So let's think about two simple spontaneous changes -- the cooling of a hot metal and the expansion of a gas -- at a molecular level and search for their common feature. https://www.youtube.com/watch?v=ZsY4WcQOrfk A hot block of…
