A teacher and a butterfly coming out of its cocoon.

Once a biology class was going

on.. The teacher was teaching the class on how a butterfly comes

out of its cocoon...

He brought a live cocoon to demonstrate a butterfly

coming out...

Unfortunately he was called out on an urgent task before

the butterfly could come out... But before he went he warned the class that

on no condition should anyone help the butterfly to come out...

He went out and after some time the cocoon opened and the butterfly

started to come out...

One boy taking pity on the butterfly's struggle helped it

to come out...

The sir returned and saw the butterfly and then asked the class...

Who helped the butterfly..

The boy raised his hand and confessed...

The sir said u did grave error in helping the butterfly...

In helping it u deprived the butterfly of it life's goal...

The initial struggle out of the cocoon should help the butterfly strengthen its wings...

now it will never fly...

We are also in some ways like this butterfly...

Now read on .....

Sometimes Struggles are exactly what we need in our life.

If we were to go through life without any obstacles,

It would cripple us.

We would not be as strong as we could have been

And we could never fly.

So next time you are faced with an obstacle,

A challenge, or a problem,

Struggle a little- then fly.

The Radar Imaging Satellite : RISAT

The PSLV-C12, carrying 300-kg Radar Imaging Satellite (RISAT-2) and 40-kg Micro Satellite ANUSAT lifted off from ISRO’s Satish Dhawan space Centre from Sriharikota on Monday 20 April 2009 .

At the end of the 48-hour countdown, the 44-meter tall four-stage PSLV-C12 blasted off from the second launch pad with the ignition of the core first stage.

The Polar Satellite Launch Vehicle, weighing 230 tonnes at the time of launch, soared into a clear sky at 6.45am(local time) from the spaceport here, about 90 km north of Chennai.

This is the 15th flight of ISRO’s workhorse PSLV, which had launched 30 satellites (14 for India and 16 for foreign countries) into a variety of orbits since 1993.

The launch vehicle carries two payloads - RISAT-2 (with all weather capability to take images of Earth) and ANUSAT (the first satellite built by an Indian University to demonstrate the technologies related to message store and forward operations).

The rocket would place both the satellites in their orbits around the earth shortly.

What’s RISAT?

RISAT is the first satellite imaging mission of ISRO (Indian Space Research Organization) using an active radar sensor system, namely a C-band SAR (Synthetic Aperture Radar) imager, an important microwave complement to its optical IRS series observations missions. The overall objective of the RISAT mission is to use the all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, and flood monitoring.

RISAT is a newly developed agile spacecraft, featuring a multi-mode and multi-polarization SAR system in C-band, providing spatial resolutions in the range of 3-50 m on swath widths ranging from of 30-240 km.


The spacecraft bus consists of a prism shape build around a central cylinder. Most of the spacecraft subsystems and the complete payload are integrated in the prism structure and the central cylinder. The spacecraft is 3-axis stabilized, developed, manufactured and integrated by ISRO/ISAC, Bangalore, India. The solar panels and some subsystems are mounted on the cuboid portion of the spacecraft. Two solar panels with high efficiency multijunction solar cells provide the S/C power; they are charging two sets of NiH2 batteries, each with a capacity of 40 Ah. Both energy sources deliver 3.5 kW of sustained DC power at 70 V regulated voltage to the payload for 10 minutes duration in each orbit. The on-orbit total spacecraft mass is about 1750 kg with about 950 kg of SAR payload mass.

Designed by the Israeli Aerospace Industries, RISAT can take images through the thickest cloud cover, rain, snow or fog conditions during night and day.

While the RISAT will be used extensively for purposes like mapping, managing natural disasters and surveying the seas, it can also see through camouflage like cloth or foliage used to conceal camps or vehicles.

RISAT will enable India to keep a watch on terror camps, military installations across boundaries, missile sites and suchlike.
However, RISAT is not India’s first spy satellite. The Technology Experiment Satellite has been used for photo-reconnaissance since 2001.

But unlike previous remote sensing satellites, RISAT is the first with a synthetic aperture radar, which gives it a day-night, all-weather snooping capability.

It should also help keep track of ships at sea that could pose a threat.
The RISAT will reduce India’s dependence on foreign suppliers like Ikonos for satellite imagery. But many more gaps need to be plugged. Despite the desperate need, India is still awaiting a dedicated military satellite

The interesting life of Isaac Newton

Sir Isaac Newton (1642-1727)

Read on for more obscure facts about the life of Isaac Newton, the world’s greatest scientist:

1. Baby Newton Wasn’t Expected to Live

In 1642, the year that Galileo Galilei died, Isaac Newton was born prematurely on Christmas Day. Named after his father, who died just three months before he was born, Isaac was a very small baby not expected to survive. His mother even said that Isaac was so small that he could have fit inside a quart mug.

2. Newton Almost Became a Farmer

Newton was born into a farming family. When he was 17, his mother insisted that he returned from school to run the family farm! Thankfully, Newton was a bad farmer and not long afterwards, his uncle successfully persuaded his mother to let him attend Trinity College in Cambridge instead.

3. Newton and His Apple: The True Story

Newton was inspired when he saw a falling apple while walking around his family’s garden at Woolsthorpe Manor, to formulate his theory of universal gravitation (some version even claimed the apple fell on his head!).
Newton himself actually said that he was staring out the window in his house when he saw an apple fall from a tree.

4. Newton was Secretive - He Rarely Published

There’s no doubt that Newton was brilliant, but what is not commonly known was that the majority of Newton’s discoveries were made between his twenty-first and twenty-seventh years. Yet, he didn’t disclose these findings to the world until years later.
Take for example Newton’s work on optics: his ground-breaking experiments on the nature of light (that ordinary white light is actually composed of a spectrum of colors) were done by 1669, when Newton was just 27 years old. Yet, he first presented his findings to the British Royal Society three years later, when he was elected as a fellow.

Newton’s secretiveness had led to many quarrels over credit. For example, when mathematician Gottfried Leibniz published his work on calculus, Newton countered that he had invented methods for that branch of math many years previously but didn’t publish, thus sparking one of the largest controversy in mathematics: who truly invented calculus ?

5. Newton was Deeply Religious …

Newton’s work, particularly the laws of motion and universal gravitation, had been used by some people to argue against the existence of God. Newton himself, however, said:
"Gravity explains the motions of the planets, but it cannot explain who set the planets in motion. God governs all things and knows all that is or can be done."
"This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent Being. … This Being governs all things, not as the soul of the world, but as Lord over all; and on account of his dominion he is wont to be called ‘Lord God’ or ‘Universal Ruler’. … The Supreme God is a Being eternal, infinite, absolutely perfect."
"Opposition to godliness is atheism in profession and idolatry in practice. Atheism is so senseless and odious to mankind that it never had many professors."

6. … But, He Didn’t Believe in Satan or the Holy Trinity

In spite of his deep religious conviction, Newton was unorthodox when it comes to his belief of the devil, spirits and ghosts. He also assailed people who claimed to be tempted by personal demons as deluded by their own imaginations.

7. Newton wrote more about religion than about science

The Bible was Sir Isaac’s greatest passion - he wrote more about religion than about science and mathematics!
Whether you believe that Newton is right or wrong about the end of the world, consider another one of his predictions that came true: that the Jews would return to Israel.
Indeed, Newton learned Hebrew, spent half his life, and devoted much more time to this pursuit than to science.

8. Newton was an Alchemist

A recently rediscovered papers of Newton revealed his secret interest in alchemy (of turning base metal into gold) and that he wrote extensively about his experiments:
Newton’s alchemical studies were kept secret during his lifetime. The making of gold and silver was a felony under an act of 1404.
Newton was a creature of his time when many scholars believed in a philosopher’s stone that could transmute base metal into gold. They tended to record their studies in wilfully obscure language.

"Give me leave to assert as my opinion," wrote the man who identified the wave nature of light and formulated the laws of motion, "that it is effectual in all the three kingdoms & from every species may be produced when the modus is understood: only mineralls produce minerals & sic de calmis. But the hidden secret modus is Clissus (1) Paracelsi (2) wch is nothing else but the separation of the principles thris purification & reunion in a fusible & penetrating fixity," Newton wrote.

9. Newton Battled Counterfeiters

In 1696, Newton became a warden of the London Mint and was given the task of stopping counterfeiting, which was rampant in those days:
He gathered much of that evidence himself, disguised, while he hung out at bars and taverns. For all the barriers placed to prosecution, and separating the branches of government, English law still had ancient and formidable customs of authority. Newton was made a justice of the peace and between June 1698 and Christmas 1699 conducted some 200 cross-examinations of witnesses, informers and suspects. Newton won his convictions and in February 1699, he had ten prisoners waiting to be executed. He later ordered all records of his interrogations to be destroyed.

10. Newton was a Politician
Newton was elected as a Member of Parliament in 1689 and served for exactly one year.

The Diabetic Foot

Diabetes is a disease that affects every part of the body, even when the diabetes is under control.Diabetics are extremely prone to foot problems. Just because you have Diabetes does not necessarily mean you will suffer from foot issues but being aware and preventative will allow you to spot foot problems which may or may not be related to the Diabetes itself. Diabetics, because of the nature of their disease, have fewer defenses against everyday wear and tear, especially where the feet are concerned. Increased blood sugar affects the feet in the following ways:

Foot problems associated with Diabetes are infections, damaged nerves and blocked arteries, all which can lead to foot ulceration. With diabetics infection and/or foot ulceration can often lead to amputation. Blocked arteries in the lower extremities can lead to severe pain so it is very important to associate diabetes with the need for proper foot care.

People with Diabetes have lower defenses against infections and ability for their body to fight them once they are infected. So minor scrapes and cuts in the foot area can quickly turn into an infectious nightmare for Diabetics. In addition the the fact that Diabetics are prone to nerve damage and arterial blockages, they may not actually feel the pain associated with a minor infection until it worsens.

Localized infections which are contained in one are of the foot or toes can be effectively treated with oral antibiotics. Infections effecting the entire foot must be treated more aggressively. High doses of oral antibiotics, intravenous antibiotics and even surgery may be required to control the infection.

Diabetic Neuropathy is simply damage to the never fibers in people with Diabetes. This becomes problematic because it affects the person’s to feel pain in the foot. So, it is vital for Diabetics to examine their feet daily and practice proper foot care and common sense hygiene.

How to fight a Diabetic Foot ?

Do's and Don'ts

Ppeople with diabetes should take very good care of their feet - regular cleansing, inspection and moisturising is needed.

It’s important to have a trained health professional check your feet at least once a year, but in between visits, people with diabetes can follow these steps to ensure their feet stay healthy.


Wash and inspect your feet daily, also between the toes. Treat any sores, blisters or cracks.

Cut the toenails straight across and file the edges round to avoid ingrown toenails.

Dry your feet properly – also between the toes.

Moisturise daily to avoid cracked heels.


Don’t let your feet soak – not even in a foot spa.

Don’t walk barefoot.

Don’t cut corns and calluses yourself.

Don’t use hot-water bottles or heaters near your feet.

If there are any signs of injury or infection in the foot, such as pain, redness, swelling, a smelly ulcer, a wound that does not heal or any other concerns, a doctor should be consulted immediately.

Some Interesting Facts About Internet

Myspace Facts

MySpace was founded by former Friendster members Chris Dewolfe and Tom Anderson in 2003. They saw opportunity to beat Friendster with more options and less restrictions for social network users. MySpace was purchased in 2005 for $580 million by Rupert Murdoch creator of a media empire that includes 20th Century Fox and the Fox television stations. MySpace has more than 40 billion page views a month. Google paid $900 million to be MySpace's search provider. MySpace runs on Microsoft .NET Framework, operating under Windows 2003 server and applications written in C# for ASP.NET.


History of

Jeff Bezon coined the term from the earlier name It was the excellent way to present large volume online bookstore. But did he have hidden intentions? It is hard to believe but in the early Internet days, when Yahoo was dominant search engine, results on one page were listed alphabetically. Amazon would always appear above its competition for a specific keywords. This could be a breaking point for Jeff to expand and became what it is today.


What Is Google?

Google, the Internet search company founded in September 1998. by Larry Page & Sergey Brin, got it's name from the word Googol, which represents number 1 followed with hundred zeros after it.


What Is Yahoo!?

Yahoo the complex internet organism has complicated name. Word "Yahoo" is shortcut for "Yet Another Hierarchical Officious Oracle". It was coined by PhD candidates at Stanford University: David Filo and Jerry Yang.
