How does Ganesh become God?

                           How does Ganesh become God?

In ancient times, there was a demon named Sindhurasur. He was troublesome and always giving trouble to people. People were fed up of him.
All went near Ganesh and told him their problem. Ganesh assured them that he will kill the demon. Likewise, he went near castle of demon. Demon's guards saw Ganesh coming on mouse.
Ganesh was a little boy then. Sindhurasur started to laugh after seeing Ganesh. He thought a small boy like Ganesh cant defeat him in battle.
Ganesh called demon for battle. Sindhurasur readily agreed. But in battle ground, as demon was watching, Ganesh grew to 4 times his original size.
Ganesh killed the demon. As name itself said, after killing Sindhurasur Ganesh became red.  At that time, saints worshipped him and offered him special type of grass called Doorva. With that, Ganesh's anger got less and he became normal again.
Till now, people worship Ganesh with Doorva.

Nitrogen Gas

                                  Nitrogen Gas

Nitrogen is the gas which is available in our atmosphere along with Oxygen, Hydrogen and Humidity. It is non toxic gas but of many use.
We all use Incandescent bulbs in our house. They give light and also heat. Inside the bulb, we can see a wire which is made of Tungsten metal. It is held between two points and through which electricity flows and it will glow thus we get light.
But inside a bulb, in the space found inside filled with Nitrogen gas. But when we put on the switch, sometimes bulb will not glow. This is because of melting of Tungsten wire due to excess heat . Then we replace the bulb with new one.
Nitrogen in soil is essential for plants. The fertilizers we use, contain this Nitrogen but not in gaseous form.

Acid + acid

                                 Acid + acid

It is a very rare combination. The acids for which we have been forbidden to touch, will form an useful combination of solvent.
The acids are ------
1. Hydrochlroric Acid (HCl)
2. Nitric Acid
These are the acids which are always dealt with utmost care even in laboratories. But when these are combined together, they form Aqua regia which is a known solvent of many use.
 About Aqua regia, we can find more literature from a PUC chemistry book.

Ozone layer

                                          Ozone layer

Nowadays there are often saying of ozone layer. Because of air pollution, ozone layer is vanishing. Ozone layer found around 25-30 meter from the surface of Earth.
The thickness of ozone layer is measured in Douglas Units. Ozone layer protect us from the bas Infrared Rays (IR rays ) of Sun. As it becomes thin, more IR rays will enter into atmosphere . Exposure to IR rays will result in skin cancer and other health problems for humans.
But how will we know the thickness of Ozone layer? It is much above us and we can not take rulers to measure the thickness of ozone layer. For that reason, special satellite named Neo 7 is there. It will measure the thickness of the layer.
Ozone is the isotope of oxygen. Its chemical formula is O3 means 3 atoms of Oxygen. The emission of CO2(carbon di oxide) due to air pollution is hazardous to the layer.

Planet mars is the 4th planet in our solar system. It is next to our planet Earth. Planet Mars is always a source of curiosity to humans.
Some say there are living organisms on Mars. America's NASA in its mission found that there were signs of flowing of water. But now there is very little amount of water and also Oxygen which are essential for living creatures.
Mars is red to look from Earth. Hence it is always referred as red planet. In our vedas  too, Mars is hailed as Angaraka meaning red in colour. Because of its colour, our ancestors branded it as the symbol of war. but what is the actual reason for red colour of Mars?
Recent studies concluded that surface of Mars is very rich in iron ore. Hence it has the red colour. If man is succeeded in his going to mars mission, the iron ore from Mars can be brought to Earth thus helping Mars to regain its original colour by emptying the iron ore !

Nuclear fission reaction

                                 Nuclear fission reaction

In nuclear bombs, nuclear fission reaction takes place. In that, an atom is divided into its smaller parts . In this type of reaction, an atom is divided into its components :by products are once again tremendous energy and heat.
Man is using this technique for making of nuclear bombs where as it can also be used for peaceful purposes like generation of electricity. But whatever  may be the reaction, there will be generation of energy and heat. It is upto us to use it for peaceful purpose.

Some facts about Sun

                                 Some facts about Sun

We all know that because of Sun, we get light and heat. But how it comes?
In universe, Hydrogen is the element which is vastly found. Similarly , in Sun too there is a very large amount of Hydrogen. In Sun nuclear fusion reaction takes place. In this reaction, 4 molecules of Hydrogen combine to form an atom of Helium.
In this reaction, a large amount of light and heat are produced as by products. The nuclear fusion reaction is opposite to nuclear fission reaction which is mainly used in making of nuclear bombs.

Some facts about Sun

                               Some facts about Sun

Sun is a medium sized star. But we see so many stars on the sky when it is dark. But all of them were seemed to be just twinkling. But Sun eventhough he is a star, he is actually heating the earth. Not like other stars. Why so?
The answer is simple. In universe, there are many stars. Sun is one of them. Compared to other stars, he is very near to Earth. Hence he looks bigger compared to other stars. Sun , because of his gravitation force has attracted the planets which now revolve around him and Earth is one of them.

The next occurance of comet Halley

                                The next occurance of comet Halley

Comet Halley is the well known comet. It is having the elliptical path and it comes visible once in every 76 years. The next occurence of the comet will be on the year 2061.
Some say ,comets are responsible for extinction of dinosaurs on planet Earth. Scientists believe that a comet might have collided with Earth and because of that large amount of dust had been erupted on the surface  and dinosaur vanished from Earth due to suffocation.

How Triveni Sangam got its name?

              
                                 How Triveni Sangam got its name?

 Triveni Sangam is the place where 3 rivers meet , namely Ganga, Yamuna and Saraswati. It is one of the sacred places in Hinduism.
Out of 3 rivers Gamga, Yamuna are the rivers which are famous and are well known. But Saraswati river is the invisible one. Some say it was present in ancient times. Scientists have also discovered the flow of river which is now hailed as Gupta Gamini.
Now coming to origin of triveni sangam. Veni is a word of Sanskrit origin. In Sanskrit , Veni = part of hair. Tri= 3. We girls when tying our hair to make a knot, we divide the hair into 3 parts. Then using those 3 parts we tie the knot.
But this way of tying the knot, while looking externally looks is made of only 2 parts.  The 3rd one is invisible to onlooker eventhough it is present. Similarly, in triveni sangam, only the rivers Ganga and Yamuna are visible flowing. But the third river Saraswati is invisible.
Hence the name Triveni Sangam.

Glass houses in Karnataka

                                    Glass houses in Karnataka

 A glass house is completely made of glass including the walls.  A famous saying in Kannada says that if a person lives in a glass house, he must not throw a small stone also at others. Because the person who got hit by stone thrown by him, reacts by again throwing a stone at glass house, the whole glass house will get shattered down. So its better be careful while passing the comments on others.
Now, the famous glass house of Karnataka is at Lalbagh garden of Bangalore. When  independence day and republic day are nearing, there will be a exhibition of various beautiful flowers and fruits. But this is not only the glass house present in Karnataka. There are 2 more places where glass houses are situated. The other places are------------------
1. It is the residence of Governor of Karnataka i.e. Raj Bhavan
2. Indira Gandhi glass house in Hubli.

Facts about magnet

                                                 Facts about magnet

We all know a magnet has 2 poles namely south and north. When another magnet comes in contact, the opposite poles of both magnets will get attract to each other.
It is not necessarily another magnet which will get attract. Things made of iron, nickel , cobalt are the ones which will get attracted by a magnet.
This theory we can use in a simple situation. We all use pins or needles etc almost everyday. If we have a floor having the white colour, then it would be very difficult to pick a pin or needle which has been fell on the floor. If it is not picked up, then it may create problem.
On this siuation, if we just slide away  the magnet on floor, then the fallen pin or needle will get attract to magnet and will get stuck to it. Thus we can safely  handle the fallen needles on floor with the help of magnet.

Confusion of King Kans

                                           Confusion of King Kans

King Kans was the uncle of Shri Krishna. Krishna is the son of Kans's sister Devaki. But Kans had evil intentions from the beginning. His father was King Ugrasena. Ugrasena was the king of Mathura. But Kans imprisoned his father and became the king.
Kans's sister Devaki married to Vasudeva. But  a voice from heaven said Kans that the 8th child of Devaki will be the cause of his death. By listening to that, Kans was scared. He imprisoned both Devaki and Vasudeva. He was keeping an eye on them.
Devaki became pregnant and gave birth to a child. But Kans came and killed the child. But my doubt is, when he had known that 8th child will be the cause for his death, he could have spared the first 7 children ! But the article is confusion of Kans not mine.
But the real confusion of Kans came now. Devaki had a miscarriage on her 7th child. But actually her womb was transferred to Rohini, wife of Nanda in Vrindavan. Thus born Balram.
Kans was confused. Devaki became pregnant again. Kans didnt know how to count. whether is it 7th or 8th !? But his courtiers said it is the 8th one. Thus , Kans arranged a tight security to couple. Krishna was born but the guards were fast asleep and Vasudev was able to exchange the children of Yashoda of Vrindavan and his wife Devaki.
Kans didnt know the children were exchanged. He came to kill his death but it was a girl child. As Kans readied himself to kill the child, child was able to free herself from Kans's clutches and she was Yogamaya. She said that the true 8 th child is growing in Vrindavan.

Monkey statistics

                                      Monkey statistics

Since yesterday , I was happy that monkeys have got good knowledge about live and let live. But it is not so. Again our coconut trees have become prey to monkey.
Early in the morning, they come to drink tender coconuts. Yesterday, monkey climbed the coconut tree and plucked nearly about 50 tender coconuts.
Out of them, it had allowed us to have a taste of only 10 . Rest all are its share. I calculated - in market, a tender coconut costs nearly Rs. 15 . In that way, I was horrified after coming to know the damage done by monkey. After drinking the tender coconut, it throws the remaining part to ground.
The sight remembers of me an battle ground after the war had been stopped. Poor coconuts are the wounded soldiers. But here I must say them as dead bodies of soldiers. They are not of  any use. These monkeys are going to empty all the tender coconuts by this way.
Yesterday, monkey was on our trees all the time. Cant it see the coconuts in others' garden? Why only us? Coconut trees must take action. That is the only remedy remaining now .

Myths about comets

                                    Myths about comets

Comets are the stars with tails ! They have a head part and also the tail part. The tail is mainly consisted of frozen ice and also dust particles.
They just follow the head part because of the gravity attraction. Comet's orbit will be  elliptical and they may revolve around a star like Sun. Same as planets revolve around Sun .
The Halley comet always come around the orbit of planet earth for every 76 years. Now since ancient time, there are myths regarding comets .  People are scared by the occurrence of these. People think if a comet is visible in sky, then it is surely going to be destruction on our planet earth.
The next  myth is that if the tail of the comet passes through earth's orbit , then there is a sure chance of tsunami. May be it all had happened as a mere coincidence, there is no scientific background for these. It is all just because of the orbit of comet.

Three cheers for monkey !

                                          Three cheers for monkey !

Yesterday afternoon, as I was sitting in sit  out I heard dogs barking. As I was wondering for the origin of chaos, I noticed the monkey on top of coconut tree infront of our house. I figured out that it must have come to drink tender coconuts.
I thought we, humans look after the coconut trees by watering it and by putting fertilizers to it. These monkeys come and drink all the tender coconuts eventhough it is a rainy season !
My father went to check the aftermath of monkey attack to our coconut trees. Guess what ? He came back holding 4 tender coconuts in hand. Monkey must had thrown it on ground.
Because of monkey, we all drank 2 glasses of tender coconut water which may cost Rs. 15 in market. Now I dont scold monkeys till it share the tender coconuts with us.
                         BOLO BANDAR KI JAI !
