Question:
Ranveer Singh Bhavnani (born 6 July 1985) is an Indian actor who appears in Hindi films. He is the recipient of several awards, including two Filmfare Awards, and is among the highest-paid actors in the country. After completing a bachelor's degree from Indiana University Bloomington, Singh returned to India to pursue his career in films. He made his acting debut in 2010 with a leading role in Yash Raj Films' romantic comedy Band Baaja Baaraat.
In January 2010, Singh was called for an audition by Shanoo Sharma, the head of the casting division for Yash Raj Films. They informed him that it was for a lead role in their film titled Band Baaja Baaraat, a romantic comedy set in the world of wedding planning. Aditya Chopra, the vice president of the company, later saw the audition tapes on video and was impressed by Singh's acting, and decided that he fit the part of Bittoo Sharma, the hero of the film. However, the director Maneesh Sharma needed some more convincing and he was called for a few more auditions over the next two weeks until they were completely convinced of his caliber. After the two weeks of testing, Singh was confirmed for the role of Bittoo, with Anushka Sharma playing the female lead.  Singh described the role of Bittoo Sharma as a typical Delhi boy. To prepare for the role, he spent time with students at the Delhi University campus. Prior to the release of the film, trade analysts were skeptical of the film's commercial potential, citing the middling response to Yash Raj Films' last few productions, the lack of a male star and the fact that the female lead, Anushka Sharma, was by then an "almost-forgotten" actress. However, Band Baaja Baaraat went on to become a sleeper hit. Singh's portrayal of Bittoo was praised, with Anupama Chopra of NDTV writing that Singh was "pitch perfect in the role of the uncouth but good-hearted small town slacker who is a bit of a duffer when it comes to matters of the heart." The film earned approximately Rs214 million (US$3.3 million) at the domestic box office. At the 56th Filmfare Awards, Singh won the award for Best Male Debut.  Following Band Baaja Baarat, Singh signed on for Ladies vs Ricky Bahl, a romantic comedy produced by Chopra and directed by Maneesh Sharma. He played a conman Ricky Bahl who cons girls for a living but finally meets his match. The film co-starred Anushka Sharma, Parineeti Chopra, Dipannita Sharma and Aditi Sharma. According to Singh, the title character had various avatars in the film, including a chirpy, entertaining side and a sinister side. Nikhat Kazmi of The Times of India wrote, "Ranveer is, well Ranveer: your average Joe kind of hero who looks convincing enough as Sunny, Deven, Iqbal, Ricky, his sundry avatars." Commercially, Ladies vs Ricky Bahl earned Rs370 million (US$5.7 million) domestically.

Question:
Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.
Salk preferred not to have his career as a scientist affected by too much personal attention, as he had always tried to remain independent and private in his research and life, but this proved to be impossible. "Young man, a great tragedy has befallen you--you've lost your anonymity", the television personality Ed Murrow said to Salk shortly after the onslaught of media attention. When Murrow asked him, "Who owns this patent?", Salk replied, "Well, the people I would say. There is no patent. Could you patent the sun?" The vaccine is calculated to be worth $7 billion had it been patented. However, lawyers from the National Foundation for Infantile Paralysis did look into the possibility of a patent, but ultimately determined that the vaccine was not a patentable invention because of prior art.  Salk served on the board of directors of the John D. and Catherine T. MacArthur Foundation.  Author Jon Cohen noted, "Jonas Salk made scientists and journalists alike go goofy. As one of the only living scientists whose face was known the world over, Salk, in the public's eye, had a superstar aura. Airplane pilots would announce that he was on board and passengers would burst into applause. Hotels routinely would upgrade him into their penthouse suites. A meal at a restaurant inevitably meant an interruption from an admirer, and scientists approached him with drop-jawed wonder as though some of the stardust might rub off."  For the most part, however, Salk was "appalled at the demands on the public figure he has become and resentful of what he considers to be the invasion of his privacy", wrote The New York Times, a few months after his vaccine announcement. The Times article noted, "at 40, the once obscure scientist ... was lifted from his laboratory almost to the level of a folk hero." He received a presidential citation, a score of awards, four honorary degrees, half a dozen foreign decorations, and letters from thousands of fellow citizens. His alma mater, City College of New York, gave him an honorary degree as Doctor of Laws. But "despite such very nice tributes", The New York Times wrote, "Salk is profoundly disturbed by the torrent of fame that has descended upon him.... He talks continually about getting out of the limelight and back to his laboratory... because of his genuine distaste for publicity, which he believes is inappropriate for a scientist."  During a 1980 interview, 25 years later, he said, "It's as if I've been a public property ever since, having to respond to external, as well as internal, impulses.... It's brought me enormous gratification, opened many opportunities, but at the same time placed many burdens on me. It altered my career, my relationships with colleagues; I am a public figure, no longer one of them."
