Why Iceland is Greeny?

Greenland: The Icy Giant at the Center of a Warming World Why Iceland is Greeny?           Far beyond the reach of most people’s daily thoughts lies Greenland, a vast and remote Arctic island that is quietly becoming one of the most geopolitically, environmentally, and economically important places on Earth. Though it’s part of the Kingdom of Denmark and home to fewer people than a small European microstate, Greenland’s immense landmass, strategic location, and untapped wealth have made it the subject of increasing global attention. A Vast and Frozen Land           Greenland is the largest island in the world, more than three times the size of France. With a population of only 56,000, it's one of the most sparsely populated places on Earth. Roughly one-third of the population resides in Nuuk, the capital, while the rest is spread across coastal settlements. Almost no one lives inland and for good reason: roughly 80% of the ...

The Invention Story of Barcodes.

The Invention Story of Barcodes:                    Without the application of barcodes, sales at stores would have been a very tedious process.  The barcodes help a lot in effectively keeping an eye over the sold out items in a store.  The brain behind the invention of barcodes should certainly be a 'business' mind. Let us explore the history of the invention of barcodes.  To start with, it is important to know what a barcode is. Barcodes                      Barcodes represent the object to which it is attached. These are machine readable.  The thickness or the width of the parallel lines and the distance between them make the unique pattern of each barcode possible.  Special devices called optical scanners are employed in scanning the barcodes. The Need of Invention:                  Only wh...

Software Localization and Social Justice - Challenges and its future.

Image
Software Localization and Social Justice                Of India's nine hundred and fifty million citizens, nine hundred million citizens are currently excluded from computer use, the Internet, and the World Wide Web (www) by the near-total absence of software in the languages which the majority of Indians speak.  Restated in the Jargon of the computer scientist, there has been virtually no "software localization" to any of the major vernacular languages of India.    Software Localization                The exclusion of almost one-sixth of the world's population from what enthusiasts term " the Information Age " raises questions about politics, culture, and software that are important not only to India, but to the entire world.  I am no India expert, but it is clear that India, the world's largest democracy, is a nation that despite communal conflicts has maintained a vibrant m...

Fibonacci Numbers : The Golden Ratio in Nature

Image
Fibonacci Numbers : The Golden Ratio in Nature Fibonacci Series                In 1202, Italian mathematician Leonardo Pisano (also known as Fibonacci, meaning "son of Bonacci") pondered over the question: Given optimal conditions, how many pairs of rabbit can be produced from a single pair of rabbit in one year? This thought experiment dictates that the female rabbits always give birth to pairs, and each pair consists of one male and one female.                           Think about it, two new born rabbits are placed in a fenced-in yard and left to breed. Rabbits can't reproduce until they are at least one month old, so for the first month, only one pair remains. At the end of the second month, the female gives birth, leaving two pairs of rabbits. When three roles around, the original pair of rabbits produces yet another pair of new born while their earlier offsprin...

 What is Nerve cells?               Nerve cells or neurons are the structural and functional units of the nervous system.               The Human Brain is made up of about 86 billion neurons and many more neuroglial cells (more than 86 billion). A nerve cell is a microscopic structure consisting of three major parts namely, cell body, dendrites and axon. Nerve cells Types of Nerve cell:     Myelinated or Medullated or White neurons:                         When the axon is enclosed by the white fatty myelin cover, it is called Myelinated or Medullated or White neurons.  This forms the white matter of our brain.     Non-Myelinated or Non-Medullated or Grey neurons:                         This neuron is not enclosed by the myelin sheath; so i...

What is Global warming? Causes of Global warming:

What is Global warming?                Global warming refers to the long-term increase in Earth’s average temperature due to human activities, initially the release of greenhouse gases into the atmosphere.             Greenhouse effect is due to global warming.  Greenhouse effect is defined as the progressive warming up of the earth surface due to high concentration of manmade carbon dioxide in the atmosphere.  It is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Global warming                The gases such as carbon dioxide (CO 2 ), Methane (CH 4 ), and Nitrous Oxide (N 2 O), trap heat from the sun, leading to a gradual rise in temperatures worldwide.  While some level of greenhouse gases is necessary to maintain Earth’s temperature, excessive emissio...
