” Why you are asked to Raise Your Window shades For Take off and Landing … ” ?
Have you ever wondered why cabin crew on commercial flights ask you to raise your window shade for takeoff and landing?
We asked around the office and got all sorts of answers, from passenger curiosity to conspiracy theories about terrorism threats.
We decided to ask Civil Aviation Safety Authority (CASA) corporate communications manager Peter Gibson to explain the real reason behind it.
“The simple answer is, for safety reasons,” Gibson told Business Insider Australia. “In case of an emergency, cabin crew need to decide which side of the aircraft is safest to disembark from. Leaving the window shade up allows them to make a quick call.”
Gibson said the measures were part of commercial airline safety procedures in Australia and applied to all large commercial aircraft.

Sundar Pichai Takes Control of Key Google Products….
In a major move by Google CEO Larry Page, Sundar Pichai, the Google executive responsible for Android, Chrome, and Google Apps will now also be seen looking after other key Google products, according to recode.net.
Page had sent out a memo to the staff on Friday on the change in the leadership of certain areas of Google’s business.
Pichai will be in charge of research, search, maps, Google+, commerce and ad products, and infrastructure, apart from his existing responsibilities. Six executives for Google’s newly added products who were directly reporting to Page will now be reporting to Pichai.
According to recode.net, this move was taken due to Page’s concern that Google may become less innovative as time progressed. Page believes that it would reduce bottleneck and he will be free to be able to expand existing business. It would help him focus on the ‘bigger picture’, reported recode.net.
For Pichai who’s initial role was to manage Chrome and later the OS and a line of netbooks, this new responsibility is a big accomplishment.
His previous promotion was in March 2012 when he took control of Google Apps and later in March 2013, when Android too came his way.
According to recode.net, Pichai is known to be ‘well-liked exec is seen as an ambassador and partnership maker’. However it adds that this move does not mean he is being considered as Google’s heir apparent.
Pichai is an Indian citizen born in Chennai in 1972. He joined Google 2004. Before that he worked at Applied Materials and at McKinsey & Co.
He is an alumnus of the Wharton School at the University of Pennsylvania, Stanford University and the Indian Institute of Technology Kharagpur.

October 24 1946…. This Date in Science…First Ever Photo of Earth From Space !!!
This date in science: First-ever photo of Earth from space
White Sands Missile Range/Applied Physics Laboratory
On October 24, 1946, a movie camera on board the V-2 rocket captured the first photo of Earth from outer space.
October 24, 1946. Were you alive at a time when we’d never seen Earth from space? Not many of us were, and it’s hard to imagine. But if you can imagine it, think how you’d have felt seeing this first-ever photograph of Earth from outer space, taken on today’s date in 1946. On this date, a group of soldiers and scientists in the New Mexico desert launched a V-2 rocket – fitted with a 35-millimeter motion picture camera – to a suborbital altitude of 105 kilometers (65 mi). The camera was destroyed after being dropped back to Earth, but the film survived.
First photo of Earth from space, October 24, 1946 via White Sands Missile Range/Applied Physics Laboratory
Air & Space magazine tells the story of this major event in space history:
Snapping a new frame every second and a half, the rocket-borne camera climbed straight up, then fell back to Earth minutes later, slamming into the ground at 500 feet per second. The camera itself was smashed, but the film, protected in a steel cassette, was unharmed.
Fred Rulli was a 19-year-old enlisted man assigned to the recovery team that drove into the desert to retrieve film from those early V-2 shots. When the scientists found the cassette in good shape, he recalls, “They were ecstatic, they were jumping up and down like kids.” Later, back at the launch site, “when they first projected [the photos] onto the screen, the scientists just went nuts.”
Before 1946, the highest pictures ever taken of the Earth’s surface were from the Explorer II balloon, which had ascended 13.7 miles in 1935, high enough to discern the curvature of the Earth. The V-2 cameras reached more than five times that altitude, where they clearly showed the planet set against the blackness of space. When the movie frames were stitched together, Clyde Holliday, the engineer who developed the camera, wrote in National Geographic in 1950, the V-2 photos showed for the first time “how our Earth would look to visitors from another planet coming in on a space ship.”
.
V-2 #21, launched on March 7, 1947, took this picture from 101 miles up. The dark area at the upper left is the Gulf of California. White Sands Missile Range/Naval Research Laboratory.
Scientists quickly got better at taking Earth’s picture. Here’s one from about six months later, taken from V-2 #21, launched on March 7, 1947. This picture is also from 101 miles up. The dark area at the upper left is the Gulf of California. Image via White Sands Missile Range/Naval Research Laboratory.
Bottom line: On October 24, 1946, a movie camera on board the V-2 rocket captured the first photo of Earth from outer space.

” அவ்வையாரின் விநாயகர் அகவல் …”
Avaiyar (meaning a very Old mother) was one of the very great women poets of ancient Tamil Nadu.(In telugu even today mother is called Avva) Apart from being a great poet, she played a very great role in the politics of those days, by making the great kings obey her.There are many references to her being a great Devotee of Lord Subrahmanya. Her well known work is AthiChoodi, which was written foer easy learning by Tamil Children. It is interesting to note that even today, Athichoodi shows the simple path to live well, for all children. Vinayagar Agaval is another one of her great works. Agaval means blank poetry and it is a song addressed to Lord Ganapathy . He is addressed as Vinayagar (he who removes obstacles) or Pillayar in Tamil. This prayer is an extremely popular one in Tamil Nadu. It clearly brings out the mastery of Avvaiyar in the Yoga, thathric practices and Saivism, possibly derived from the contribution of Sidhas in Tamil Nadu and the Tamil Nadu Saivism

Message For the Day….Advice To Children…
Why an Apple a Day Keeps You Away From Your Doctor !!!
Why Are Apples So Healthy?
|
We all know that old saying: “An apple a day keeps the doctor away.“
But have you ever wondered why that is? How one apple a day can bring about significant health benefits? If you have, then you’ll be glad to read this article. From strengthening the immune system, through preventing cancerous growths and to losing weight, say hello to your one apple a day!
 How do apples do what they do?
An important research published in 2008 by the German cancer research center, showed that apples offer a significant health advantage. When comparing between a group that had less than one apple per day and a group that had one or more apples a day, the latter was found to have less risk of mouth cancer, larynx cancer, breast cancer, intestinal cancer, kidney cancer and ovarian cancer.
These findings support a new research performed at Cornell university, showing that the peel of the apple has strong anti-oxidant properties, a powerful block against the influences of breast cancer cells. Researchers found that the higher the concentraion of apples, the lower the concentration of cancerous cells.
Cancerous growths are uncontrollable growths of cells independently spreading through the body. The growths are based on three principal levels: The first stage causes mutations in cell DNA. The second, when the growth becomes malignant and grows faster, and finally when it metastases and spreads throughout the body.
In the case of a cancerous growth, apples aren’t only used as anti-oxidants, but also improve the function of the immune system, which helps clean out the growths at the early stages.
In addition to boosting the immune system and fighting cancerous growths, apples also help control the levels of cholesterol and sugars in the blood, prevent heart disease and improve mouth hygiene. The fact that they contain more than 80% water and a long line of essential vitamins, makes them one of the healthiest foods available.
The secret is in the nutritional fibers
Apples are considered a vital source of nutritional fibers. Eating one apple a day (with peel) can award us about 4.4 grams of nutritional fibers, which is 1/5 of our entire day’s recommended amount.
Nutritional fibers are materials found in foods that come from plants, and have a very important role in stimulating the digestive system and encouraging its function. Since they are not digested and taken apart in the body, they sate our hunger for a longer period of time. Extensive research has shown that those that do not get their daily recommended amount (at least 25 grams a day), deny themselves a host of health benefits. In addition, the researchers found that consuming these fibers is quite the effective method of losing weight.
The secret is in the chewing. Drinking apple juice will not bring about the same health benefits. We’d be happy to receive the essential sugars and vitamins, but we would not get the fibers.
A research conducted in China found that chewing can help the body regulate the amount of calories it absorbs from food.
What does this have to do with apples?
 Everything. Apples are a terrific source of nutritional fibers, especially a group of fibers called Pectin. This is a group of complex carbohydrates that regulate our bowels, improve good cholesterol rates and is a powerful anti-oxidant and anti-bacterial.
Researchers from UCLA have shown that consuming pectin instead of regular fibers, doubles the time it takes the stomach to empty from one hour to two. Meaning that we don’t feel hungry for a longer time. In fact, a recent research paper entitled: “Weight Loss Associated with a Daily Intake of Three Apples or Three Pears among Overweight Women”, shows that women suffering from overweight and were instructed to eat an apple or pear before each meal, lost significant weight, just for doing so. The women in the experiment were asked to eat regularly and just add the apple before the meal. What happened was that the apples and fibers crowded the stomach, increased the feeling of being full, and made the body absorb less calories.
Other sources of nutritional fibers are: Pears, Peaches, peas, carrots, seeds, nuts, peel of fruits and vegetables, legumes, whole grains, oats and whole wheat. But apples offer many more advantages.
So if you want to:
Lose weight, eat one apple a day.
Strengthen your immune system, eat one apple a day.
Control the level of cholesterol, eat one apple a day.
Prevent the spread of cancerous cells, eat one apple a day.
And if you want to keep the doctor away – EAT ONE APPLE A DAY!

Image of the Day… MoonBows !!!
Moonbows!
A moonbow is like a rainbow, but fainter, caused by moonlight.
Orion was setting when Rob Ratkowski captured this rare moonbow in Hawaii in May 2004. The planet Venus is the bright object inside the bow. A moonbow is like a rainbow, but fainter, caused by moonlight. Les Cowley at the great website Atmospheric Optics says:
Moonbows are rare because moonlight is not very bright. A bright moon near to full is needed, it must be raining opposite the moon, the sky must be dark and the moon must be less than 42º high. Put all these together and you do not get to see a moonbow very often! To the unaided eye they usually appear, as in the small image, without color because their light is not bright enough to activate the cone color receptors in our eyes. Nonetheless colors have been reported and might be seen when the moon is bright.
Bottom line: Moonbows!
