About Program

This is part of its efforts to popularize science to the general public and students who are pursuing science as their career. TNSF attempt to focus on students on higher science as everyone knows that learning of science at college within the curriculum is not enough to acquire holistic knowledge of science at the appropriate time. Hence, to fill the gap between what students are acquiring through the curriculum and what it is required, TNSF is planning its activities on higher science to students who are pursuing higher education

"I do not consider myself the father of the release of atomic energy. My part in it was quite indirect. I did not, in fact, foresee that it would be released in my time. I believed only that it was theoretically possible. It became practical through the accidental discovery of chain reaction, and this was not something I could have predicted." - Einstein

The call for complete nuclear disarmament is as old as the nuclear era itself. India was among first nations to argue for global disarmament. Many illustrious intellectuals, like Bertrand Russell, Albert Einstein and Leo Szilard actively worked for this cause. But as the Cold War warmed up, these weapons seemed to be here to stay. By the mid-seventies, the world had over 60,000 nuclear bombs, mostly in the US and USSR, enough to destroy the whole world many times over.

The US and USSR (later Russia) did reduce their nuclear arsenals in stages, through a sequence of Treaties, but still leaving a stock of thousands of bombs each,. Meanwhile, in addition to the UK, France and China, more nations began producing nuclear weapons including Israel, India, Pakistan and lately, N Korea, increasing the probability of a nuclear catastrophe.

However, hopes for a world without nuclear weapons enjoyed a revival some 10 years ago, led by US President, Mr.Barack Obama. He made universal disarmament a major policy issue and followed it up very energetically. Other world leaders welcomed his initiatives, including President Medvedev of Russia.

But despite all this, harsh realities and pragmatism began asserting themselves again and the prospects of total disarmament are receding. The vision of a world without nuclear weapons is back to being a distant dream.

In this talk we will start with a brief discussion of the effects of a nuclear explosion, to give a realistic idea of the damage a typical small 20kT weapons can cause, We will then trace the above story of arms reduction efforts from the beginning to the present, for a general audience.

கடந்த 1945 ஆம் ஆண்டில் ஆகஸ்ட்,6,9 தேதிகளில் அமெரிக்கா ஜப்பானின் ஹிரோஷிமா-நாகசாகி நகரங்களின் மீது நடத்திய நிகழ்ந்த அணுகுண்டுத் தாக்குதலால் 3 இலட்சத்திற்கும் மேலான அப்பாவி மக்கள் பலியானார்கள். ஹிபாகுஷாக்கள் என்ற தனி இனமே உருவானது. அதன் தாக்கம் இன்றுவரை ஜப்பானிய மக்களிடையே இருந்துகொண்டுதான் இருக்கிறது. அனாலும் இன்றும் உலகின் பல பகுதிகளில் போர்களும் பலிகளும் தொடர்ந்துகொண்டுதான் இருக்கிறது.

எனவே தான் தமிழ்நாடு அறிவியல் இயக்கம் ஆகஸ்ட், 6,9 தேதிகளை போர்களுக்கு எதிரான தினமாக அனுசரித்து அறிவியல் அமைதிக்கே, அறிவியல் ஒற்றுமைக்கே, அறிவியல் உலக சமாதானத்திற்கே என்கின்ற முழக்கங்களை முன்வைத்து குழந்தைகள், ஆசிரியர்கள் மற்றும் பொதுமக்களிடையே ஓவியம், கட்டுரை, கவிதை எனப் பல்வேறு போட்டிகளையும் பேரணி, மனிதச்சங்கிலி, கருத்தரங்குகள் போன்ற பல நிகழ்ச்சிகளையும் கடந்த பல ஆண்டுகளாக நடத்தி வருகிறது.
