Problem: Kevin Moore (born May 26, 1967) is an American keyboardist, vocalist, composer, and founder of the Chroma Key music project. He is also a former member of the American progressive metal/rock band Dream Theater, co-founder of the progressive rock supergroup O.S.I. and has composed film soundtracks. Throughout his career, he has become known for his emotional music and lyrics, nomadic lifestyle and use of spoken word samples. Moore started his music career in progressive metal band Dream Theater.

Dream Theater's debut studio album was 1989's When Dream and Day Unite, which earned the group comparisons to well-known progressive rock bands such as Rush and Queensryche. Their big breakthrough, however, came in 1992 with the album Images and Words, featuring the band's highest charting single to date, "Pull Me Under". The song, which included lyrics by Moore, reached #10 on the Billboard Mainstream Rock Tracks chart. Following their relentless touring in support of the second album, the band also went on to release a live album, Live at the Marquee, and a video, Images and Words: Live In Tokyo. The video's extensive documentary footage would subsequently introduce many fans to Moore's ironic sense of humor. In 1994, the band released its third studio album, Awake, which was the band's highest charting album to date with Moore, reaching #32. The album featured Moore's signature song, a haunting piano-driven ballad called "Space-Dye Vest." Shortly before the album was mixed, though, Moore announced to the rest of the band that he wished to concentrate on his own musical interests and would be quitting Dream Theater. According to Portnoy, Moore became interested in the independence of working on his own as opposed to the compromise of a band environment. Although Dream Theater has since invited him to play reunion shows, Moore has said he prefers to move forward as opposed to looking back. He also declined to take part in the official Dream Theater biography titled Lifting Shadows. During his time in Dream Theater, Moore wrote the lyrics to songs on each of the band's albums and also to some of the band's demos and b-sides. On When Dream and Day Unite, he wrote "Light Fuse and Get Away" and "Only a Matter of Time." On Images and Words, he penned "Pull Me Under", "Surrounded", "Wait for Sleep", and parts of "Take the Time." On Awake, the songs "6:00", "Lie", and "Space-Dye Vest" all featured his lyrics. Demos with his lyrics include "Don't Look Past Me," the final verse of "To Live Forever '94," "A Vision," "Vital Star," and "Two Far."

Problem: 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."

Do buildings last longer using this system?
