NOVEMBER 2013 VOL. 11 NO. 11 PRICE: j 2.00 Hundred Years of the Atom A Campaign centred around the centenary of the discovery of the atomic structure

The discoveries of the X-rays, radioactivity, the electron, quantum theory, and relativity during the golden decade 1895-1905 brought about a total revolution in the way we Inside perceive nature; and ushered in the era of Modern Science. Discoveries made during this period gave fo'ks"k ys[k rise to a spate of developments in physical and life sciences that has made the world we live in today. The discovery of the electron in 1897 prompted scientists to channelise their efforts to understand Hundred Years of the the structure of the matter. J. J. Thomson, the Atom discoverer of the electron, proposed the plum- pudding model of the atom. However, the discovery Structure of Atom : Source : Vinod Raina: Architect of of the atomic nucleus by Ernest Rutherford in 1911 simple.wikipedia.org a new education established a dense core (nucleus) at the centre with positive charge and system electrons with negative charge moving around it at large distances like planets around the Sun. This model had fundamental flaws as it did not confirm to the Fun In Maths established laws of physics. Niels Bohr resolved this problem by introducing the concept of stationary orbits, or the orbits in which the electrons orbited Dr Narendra Dabholkar: without radiating away energy. This explained the experimental data for the A fighter against hydrogen atom well and established the structure of the atom as proposed by obscurantism in India him. Later, contributions of Wolfgang Pauli with his Exclusion principle put the Bohr's theory of the atomic structure on a firm footing. This breakthrough Club Speak could explain aspects like atomic levels, spectra of various elements, electronic configurations in various atoms and the periodic table, chemical reactions, and as a result helped unravel phenomena in life sciences as well. The structure of DNA could be established only through a thorough understanding of atomic and molecular properties. Development of quantum mechanics and its applications related to atomic phenomena in 1930s opened up new vistas and contributed to technologies that have become a part of our daily life.

In the span of the last two months, India lost two stalwarts, Dr. Dhabholkar & Dr. Vinod Raina, who strived throughout their live for developing scientific temper, spirit of enquiry in the country though their works. Particularly, it is shocking to note that Dr. Dhabholkars death was not a natural death, he was brutally murdered by those who were opposed to his ideas. In this issue we are publishing a brief orbituary of these two personalities written by Sandeepan Dhar, a science activist. Dr. Dabholkar was a legendary figure in and contributed significantly in spreading scientific temper and spirit of inquiry. His major contribution was in framing the Anti-superstition and Black Magic Bill, a constitutional mandate of the country. Dr. Vinod Raina was eminent educationalist and architecture of modern education of India. He not only worked to make science teaching easy but developed a new pedagogy. His initiative was the welknown Hoshangabad Science Project. He was also associated Dr Narendra Dabholkar with literacy missions and People's Science in India.
