Different Models Of Solar System

I like to share with you the four models of solar system that I know about. The one that is in the school books that we all know is the Heliocentric Model. 

Nicolaus Copernicus presented the Heliocentric Model of the Solar System. Copernicus was a Polish who was born in 1473 AD and died in 1543 AD. Many people think this is the model of the solar system because this is the model that is given in the school books. In this model, the sun is stationary. Earth and the others planets revolve around the sun.

But, there are other people who presented different models of the solar system. Claudius Ptolemy, a Greek Mathematician, Geographer, Astronomer and Astrologer who was born years before Copernicus was born presented a model of Solar System called as the Geocentric Model. Ptolemy was born in the year 90 AD and died in 168 AD. He said that the earth is stationary, the moon, sun and the other planets move around the earth in circular orbits.

Next model that I would like to share is the Tychonic System, presented by Tycho Brahe, a Danish Astronomer who had a very long mustache. Tycho Brahe was born in 1546 AD, three years after Copernicus died. Tycho Brahe died in 1601 AD. Tychonic System presents a stationary Earth with moon and sun revolving around it. Mercury and Venus revolves around the sun. Mars and the planets beyond Mars revolves around the Earth and The Sun. 

Before any of these people, many many many years back, Sage Veda Vyasa, one who classified the Vedas wrote an ancient book called as Srimad Bhagavata. In that, he wrote in the 5th canto that the Earth is stationary and the moon and the sun revolves around the Earth. Mercury and Venus revolves around the sun. And Mars and the other planets beyond Mars revolve around the Earth and the Sun. The Tychonic System is a bit similar to the Vedic Model given in the Srimad Bhagavata.

The school book talks about the model presented by Copernicus. I wonder why the opinion of other astronomers are not given in the school book. Now, which model is the reality?

Modern Science says that Nebula is a cloud of gas and dust in outer space. A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases. 

Me and my Amma are researching about nebulae and we wonder how the patterns of nebulae is similar to some of the things that we see in our life.  Hubble Space Telescope is a space telescope that is launched in 1990 by space organizations like NASA and ESA. This telescope is sending lots of pictures of nebulae. These pictures are so unbelievable because these nebulae looks like many things that I see around in my life in the form of rangoli, yantras and mandalas. These pictures that the hubble space telescope is sending are so fascinating.

What Is Geography?

Today, I learnt about what Geography is. Geography is the study of the earth, cities, countries, people and their lifestyles and also of different kinds of land forms and water bodies. 

Geography tells us about

- cities and countries, mountains, rivers and deserts

- why it is hot in summer and cold in winter

- things like earthquakes and floods

- our environment

- how our environment is getting damaged

- how to protect it

- how and why the world is changing globally 

- our natural environment and pressures they face

- places/communities in which we live and work

- interconnectedness of world and the communities that live in it

The Fish Incarnation Of Vishnu And Comparative Studies

Matsya Avatara Sculptor, SriRangam

I will share with you the story of Matsya Avatara. This is how it all began. Once upon a time, there was a sage named Satyavrata. One day, when he was taking bath in a river, he found a fish in his hand. That fish told the sage to not let the fish get into the water again, otherwise the fish would be eaten by its predators. So, Satyavrata decided to take the fish along with him. He put the fish in his kamandala (holy vessel) and went back home. After Satyavrata reached home, he got a surprise. The fish became bigger that it could not fit into the kamandala. Then, Satyavrata took the fish and put it in a larger pot. But, the fish became more bigger than the pot. Satyavrata put the fish into a pond. The fish grew more larger than the pond. Satyavrata was puzzled. He decided to put the fish into the ocean. As soon as he put the fish into the ocean, the fish hooted and said, "Oh Sage, why are you doing this injustice to me by putting me back in the ocean. There are more dangerous predators in the ocean that can easily eat me up". Satyavrata said, "Oh great fish, you must be Sriman Narayana incarnate, are you here to teach me a lesson?"
