paragraph_text: He started the Visibility Laboratory at the Massachusetts Institute of Technology in 1939/40. It was the brainchild of Duntley and MIT physics chair Dr. Arthur C. Hardy. It was focused on applying optics to such problems as camouflage, misdirection of aerial bombardment, target location, visibility of submerged objects at sea. In 1952, Roger Revelle and Quimby Duntley agreed that the laboratory would become part of the Scripps Institution of Oceanography in San Diego, and the U.S. Navy Bureau of Ships agreed to pay for the move. The work of the laboratory centered on the transmission of visible light through the atmosphere and water and the related problems of image formation and recognition. The nature of much of the research required measurements of the optical properties of the ocean or atmosphere for which no instruments existed. As a result of these requirements, many unique and very specialized instruments were developed by the laboratory, many of which were based on concepts or optical designs devised by Duntley. He earned the academic rank of Professor in 1966 and taught at Scripps Institution of Oceanography and at the Department of Applied Physics and Information Science (APIS) at UCSD until his retirement.

paragraph_text: India rejected Chinese demands that the torch route be clear of India's 150,000-strong Tibetan exile community, by which they required a ban on congregation near the curtailed 3 km route. In response Indian officials said India was a democracy, and "a wholesale ban on protests was out of the question". Contradicting some other reports, Indian officials also refused permission to the "Olympic Holy Flame Protection Unit". The combined effect is a "rapid deterioration" of relations between India and China. Meanwhile, the Tibetan government in exile, which is based in India, has stated that it did not support the disruption of the Olympic torch relay.

paragraph_text: India: Due to concerns about pro-Tibet protests, the relay through New Delhi on April 17 was cut to just 2.3 km (less than 1.5 miles), which was shared amongst 70 runners. It concluded at the India Gate. The event was peaceful due to the public not being allowed at the relay. A total of five intended torchbearers -Kiran Bedi, Soha Ali Khan, Sachin Tendulkar, Bhaichung Bhutia and Sunil Gavaskar- withdrew from the event, citing "personal reasons", or, in Bhutia's case, explicitly wishing to "stand by the people of Tibet and their struggle" and protest against the PRC "crackdown" in Tibet. Indian national football captain, Baichung Bhutia refused to take part in the Indian leg of the torch relay, citing concerns over Tibet. Bhutia, who is Sikkimese, is the first athlete to refuse to run with the torch. Indian film star Aamir Khan states on his personal blog that the "Olympic Games do not belong to China" and confirms taking part in the torch relay "with a prayer in his heart for the people of Tibet, and ... for all people across the world who are victims of human rights violations". Rahul Gandhi, son of the Congress President Sonia Gandhi and scion of the Nehru-Gandhi family, also refused to carry the torch.
