PANCHTATAVAS - MYSTERIOUS WORLD OF MATTER

According to Ancient Indian philospers all matter of this universe is made up of five basic constituents commonly called panch tatavas. Indian philospher Maharishi Kanad around 500 BC postulated that matter is divisible. The smallest indivisible matter were named as parmanu. Greek philosphers named this indivisible particles atoms. In 1808 John Dalton suggest that the atom was indivisible and industructible. After the discovery of electron and proton inside the atom, led to the failure of Daltons theory. In the thirty years between the discovery of neutron in 1932 to the middle of 1962, more than thirty new particles were found, which were thought to be the builders of matter in the universe. Therefore it was established beyond doubt that all the particles discovered are not fundamental but have complex nature. In 1964 Gell-Mann and Zweing proposed that most of these particles called Quarks. Nearly 200 elementary particles were discovered so far. It appears that our search for the ultimate builder is not in a concluding stage but we are reaching towards the goal in stages. In this way we can say that the mysterious world of elementary particles and Quark is still mysterious. The same is written in Vedas and Purana that the search of ultimate particle will go on and on.
