James Watt  (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.
From an early age Watt was very interested in chemistry. In late 1786, while in Paris, he witnessed an experiment by Berthollet in which he reacted hydrochloric acid with manganese dioxide to produce chlorine. He had already found that an aqueous solution of chlorine could bleach textiles, and had published his findings, which aroused great interest among many potential rivals. When Watt returned to Britain, he began experiments along these lines with hopes of finding a commercially viable process. He discovered that a mixture of salt, manganese dioxide and sulphuric acid could produce chlorine, which Watt believed might be a cheaper method. He passed the chlorine into a weak solution of alkali, and obtained a turbid solution that appeared to have good bleaching properties. He soon communicated these results to James McGrigor, his father-in-law, who was a bleacher in Glasgow. Otherwise he tried to keep his method a secret.  With McGrigor and his wife Annie, he started to scale up the process, and in March 1788, McGrigor was able to bleach 1500 yards of cloth to his satisfaction. About this time Berthollet discovered the salt and sulphuric acid process, and published it so it became public knowledge. Many others began to experiment with improving the process, which still had many shortcomings, not the least of which was the problem of transporting the liquid product. Watt's rivals soon overtook him in developing the process, and he dropped out of the race. It was not until 1799, when Charles Tennant patented a process for producing solid bleaching powder (calcium hypochlorite) that it became a commercial success.  By 1794 Watt had been chosen by Thomas Beddoes to manufacture apparatus to produce, clean and store gases for use in the new Pneumatic Institution at Hotwells in Bristol. Watt continued to experiment with various gases for several years, but by 1797 the medical uses for the "factitious airs" had come to a dead end.

Rani Mukerji (born 21 March 1978) is an Indian actress. She has won several awards, including seven Filmfare Awards. Her film roles have been cited as a significant departure from the traditional portrayal of women in Hindi cinema. Although Mukerji was born into the Mukherjee-Samarth family, in which her parents and relatives were members of the Indian film industry, she did not aspire to pursue a career in film.
Mukerji portrayed a rape victim who is forced to marry her rapist in Raja Ki Aayegi Baraat, which released in 1997. Although the film was a commercial failure, Mukerji's performance was praised, and she won a special recognition trophy at the annual Screen Awards ceremony. Following the film's poor showing at the box office, Mukerji returned to college to complete her education. However, inspired by her cousin Kajol's success in Bollywood, she decided to pursue a full-time career in films.  In 1998, Mukerji starred opposite Aamir Khan in Vikram Bhatt's Ghulam (1998), her first commercial success. Though her role in the film was small, the song "Aati Kya Khandala" earned her widespread recognition. Due to Mukerji's broken voice texture, Bhatt hired a dubbing artist with a much higher pitched voice to dub for her lines. When asked if the director's decision to not use her voice in the film affected her, she said that her voice was dubbed as it "did not suit the character".  Later that year, Karan Johar cast Mukerji opposite Shah Rukh Khan and Kajol in his directorial debut Kuch Kuch Hota Hai. The role was originally written for Twinkle Khanna, but when she rejected it, Johar signed Mukerji on the insistence of Khan and Aditya Chopra. Johar had originally intended that a dubbing artist dub Mukerji's lines in the film, but she improved her diction and eventually dubbed for her own lines. She portrayed Tina Malhotra, a college student who is in a relationship with Khan's character. Writing for India Today, film critic Nandita Chowdhury considered Mukerji to be the scene-stealer and added, "Oozing oomph from every pore, she [..] proves herself an actress whose time has come." Kuch Kuch Hota Hai proved a breakthrough for Mukerji; it emerged as a blockbuster in India and abroad with earnings of over Rs1.03 billion (US$16 million), and won eight Filmfare Awards, including a Best Supporting Actress trophy for Mukerji.  Following the success of Kuch Kuch Hota Hai, Mukerji played leading roles in the social drama Mehndi (1998) and the comedy Hello Brother (1999). Both these films were critical and commercial disappointments which failed to propel her career forward.

What was her debut movie?
Mukerji portrayed a rape victim who is forced to marry her rapist in Raja Ki Aayegi Baraat, which released in 1997.
