Question:
Belinda Jo Carlisle was born in Hollywood, Los Angeles, California on August 17, 1958 to Harold Carlisle, a gas station employee, and his wife, Joanne (nee Thompson), a homemaker. Her mother met her father, who was twenty years her senior, at age eighteen, and Carlisle was born nine months later. She was named after her mother's favorite film, Johnny Belinda (1948). Carlisle was the first of seven siblings, with three brothers and three sisters.
Carlisle's first venture into music was in 1977 as drummer for the punk rock band the Germs, under the name Dottie Danger. She was recruited into the band by Lorna Doom, whom she had met in an art class while a student at Thousand Oaks High School. However, her time in the band was short due to her contracting mononucleosis, and she never recorded or performed live with the Germs. According to Pat Smear, upon quitting, she introduced her friend, Donna Rhia, who became her replacement. Carlisle does appear on one recording introducing the band at a 1977 performance at the Whisky a Go Go, heard on the live album Germicide (1977). Around this time Carlisle did some back-up singing for Black Randy and the Metrosquad.  Soon after leaving the Germs, she co-founded The Go-Go's (originally named the Misfits), with friends and fellow musicians Margot Olavarria, Elissa Bello, and Jane Wiedlin. Olavarria and Bello were soon out of the group and the new line-up included bassist-turned-guitarist Charlotte Caffey, guitarist-turned-bassist Kathy Valentine, and drummer Gina Schock. All five women were largely untrained musicians, and Carlisle recalls having to use tape as fret markers during their initial songwriting: "[Charlotte] had to show us how to plug in our amps," she said.  The Go-Go's would go on to become one of the most successful American bands of the 1980s, helping usher new wave music into popular American radio, and becoming the first all-female band who wrote their own music and played their own instruments to ever achieve a No. 1 album, Beauty and the Beat, which featured the hits "We Got the Beat" and "Our Lips Are Sealed". The Go-Go's recorded two more studio albums on I.R.S. Records, including 1982's Vacation, which went gold. "Head over Heels", from their 1984 album Talk Show, made it to No. 11.  In 1984, Carlisle made a foray into acting in the movie Swing Shift, starring alongside Goldie Hawn and Kurt Russell.

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."
