Question: Rahul Bose was born to Rupen and Kumud Bose on 27 July 1967. He describes himself as "...half Bengali; one-fourth Punjabi and one-fourth Maharashtrian." Bose's first acting role was at age six when he played the lead in a school play, Tom, the Piper's Son.

Bose started his acting career on the Mumbai stage in Rahul D'Cunha's Topsy Turvey and Are There Tigers In The Congo?. D'Cunha's aunt was the casting director for director Dev Benegal's film English, August and suggested that Bose should play the lead role. After filming a screen test, Benegal decided to cast him as civil servant Agastya Sen. Based on the novel of the same name by Upamanyu Chatterjee, English, August was one of the first Hinglish films and gained Bose international recognition when it became the first Indian film to be purchased by 20th Century Fox and won several awards at international film festivals. After English, August Bose found work in television; he was offered a role in India's first English-language television serial, A Mouthful of Sky and also co-hosted BBC World's Style! with Laila Rouass. In 1998 he appeared in Kaizad Gustad's Bombay Boys with Naseeruddin Shah and starred in Dev Benegal's second film, Split Wide Open. To prepare for his role as a roving water vendor, Bose lived in Mumbai's slums and observed a drug dealer for two weeks. He later cited this time--along with the 2002 Gujarat riots--as the beginning of the awakening of his social conscience. Although Split Wide Open was controversial in India because of its depictions of sexual abuse, Bose received the Silver Screen Award for Best Asian Actor at the 2000 Singapore International Film Festival for his performance. He also performed abroad in the Leicester Haymarket in England where he starred in the English version of Tim Murari's play, The Square Circle. In 1997, Bose was cast to play the role of Saleem Sinai in the BBC adaptation of Salman Rushdie's novel Midnight's Children. The project was eventually canceled after the Indian and Sri Lankan governments refused to allow filming. After seeing Bose in English, August, director Govind Nihalani cast him in the villain role opposite Ajay Devgan in the mainstream film Thakshak. The film was not a financial success, although Bose received positive reviews. In 2001, Bose made his directorial debut with Everybody Says I'm Fine!. Starring Rehaan Engineer and Koel Purie and featuring Bose in a supporting role, Everybody received mixed reviews from critics, but won Bose the runner-up John Schlesinger Award for best directorial debut at the 2003 Palm Springs International Film Festival. In 2002, Bose starred opposite Konkona Sen Sharma in Aparna Sen's art film Mr. and Mrs. Iyer. The film, a critique of communal violence, was a critical success and won several awards at international film festivals as well as three National Film Awards.

Question: Fazlur Rahman Khan (Bengali: phjlur rhmaan khaan, Fozlur Rohman Khan) (3 April 1929 - 27 March 1982) was a Bangladeshi-American structural engineer and architect, who initiated important structural systems for skyscrapers. Considered the "father of tubular designs" for high-rises, Khan was also a pioneer in computer-aided design (CAD). He was the designer of the Sears Tower, since renamed Willis Tower, the tallest building in the world from 1973 until 1998, and the 100-story John Hancock Center. Khan, more than any other individual, ushered in a renaissance in skyscraper construction during the second half of the 20th century.

Khan's central innovation in skyscraper design and construction was the idea of the "tube" structural system for tall buildings, including the framed tube, trussed tube, and bundled tube variants. His "tube concept", using all the exterior wall perimeter structure of a building to simulate a thin-walled tube, revolutionized tall building design. Most buildings over 40 stories constructed since the 1960s now use a tube design derived from Khan's structural engineering principles. Lateral loads (horizontal forces) such as wind forces, seismic forces, etc., begin to dominate the structural system and take on increasing importance in the overall building system as the building height increases. Wind forces become very substantial, and forces caused by earthquakes, etc. are important as well. The tubular designs resist such forces for tall buildings. Tube structures are stiff and have significant advantages over other framing systems. They not only make the buildings structurally stronger and more efficient, but also significantly reduce the structural material requirements. The reduction of material makes the buildings economically more efficient and reduces environmental impact. The tubular designs enable buildings to reach even greater heights. Tubular systems allow greater interior space and further enable buildings to take on various shapes, offering added freedom to architects. These new designs opened an economic door for contractors, engineers, architects, and investors, providing vast amounts of real estate space on minimal plots of land. Khan was among a group of engineers who encouraged a rebirth in skyscraper construction after a hiatus of over thirty years. The tubular systems have yet to reach their limit when it comes to height. Another important feature of the tubular systems is that buildings can be constructed using steel or reinforced concrete, or a composite of the two, to reach greater heights. Khan pioneered the use of lightweight concrete for high-rise buildings, at a time when reinforced concrete was used for mostly low-rise construction of only a few stories in height. Most of Khan's designs were conceived considering pre-fabrication and repetition of components so projects could be quickly built with minimal errors. The population explosion, starting with the baby boom of the 1950s, created widespread concern about the amount of available living space, which Khan solved by building upward. More than any other 20th-century engineer, Fazlur Rahman Khan made it possible for people to live and work in "cities in the sky." Mark Sarkisian (Director of Structural and Seismic Engineering at Skidmore, Owings & Merrill) said, "Khan was a visionary who transformed skyscrapers into sky cities while staying firmly grounded in the fundamentals of engineering."
