List of tallest buildings in the world

This list of tallest buildings in the world ranks skyscrapers by height. Only buildings with continuously occupiable floors are included, thus non-building structures, including towers, are not included. (See List of tallest buildings and structures in the world).

Ranking criteria and alternatives

The international non-profit organization Council on Tall Buildings and Urban Habitat (CTBUH) was formed in 1969 and announces the title of "The World's Tallest Building" and sets the standards by which buildings are measured. It maintains a list of the 100 tallest completed buildings in the world. The organization currently ranks Burj Khalifa in Dubai as the tallest at 828 m (2,717 ft). The CTBUH only recognizes buildings that are complete, however, and some buildings listed within these list articles are not considered complete by the CTBUH.

In 1996, as a response to the dispute as to whether the Petronas Towers or the Sears Tower was taller, the council listed and ranked buildings in four categories:

Building

A building or edifice is a structure with a roof and walls standing more or less permanently in one place, such as a house or factory. Buildings come in a variety of shapes, sizes and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, to land prices, ground conditions, specific uses and aesthetic reasons. To better understand the term building compare the list of nonbuilding structures.

Buildings serve several needs of society – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the outside (a place that at times may be harsh and harmful).

Ever since the first cave paintings, buildings have also become objects or canvasess of artistic expression. In recent years, interest in sustainable planning and building practices has also become an intentional part of the design process of many new buildings.

Buildings 1992

Buildings 1992 is a public art work by American artist Susan Walsh, located on the northwest side of Milwaukee, Wisconsin. The architectural sculpture was created for the Milwaukee Fire Department station at the intersection of 103rd Street and Fond du Lac Avenue.

Description

Buildings 1992 depicts the frames of four tall, rectangular buildings. Each building has two doors at its base. Two of the buildings have triangular roofs. One has an arched roof. The entire work rests on a square concrete base.

Homecoming (Heroes)

"Homecoming" is the ninth episode of the first season of the NBC science fiction drama series Heroes.

Plot

The episode begins with Claire and her friend Zach walking into the high school amphitheater with lunch as Claire's former cheerleader friends wait anxiously for the results of the Homecoming Court vote. Claire downplays the entire ritual, but Zach encourages her to check the posting and see if she had won. To Claire's surprise, she has been voted Homecoming Queen, with her main rival, Jackie, merely a member of the court. Astonished, Claire and the rest of the cheerleaders turn around to see much of the student body proclaiming congratulations and support for Claire. She later discovers that Zach had been campaigning for her, working to win the "unpopular vote" by letting everyone know that Claire is not like the popular Jackie. Jackie, however, spoils the moment in an attempt to deflate Claire's victory by poking fun at Zach. Claire, beginning to see the importance of Zach's friendship to her, promptly punches Jackie in the face.

Flight dynamics

Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle influence its speed and attitude with respect to time.

In fixed-wing aircraft, the changing orientation of the vehicle with respect to the local air flow is represented by two critical parameters, angle of attack ("alpha") and angle of sideslip ("beta"). These angles describe the vector direction of airspeed, important because it is the principal source of modulations in the aerodynamic forces and moments applied to the aircraft.

Spacecraft flight dynamics involve three forces: propulsive (rocket engine), gravitational, and lift and drag (when traveling through the earths or any other celestial atmosphere). Because aerodynamic forces involved with spacecraft flight are very small, this leaves gravity as the dominant force.

Aircraft and spacecraft share a critical interest in their orientation with respect to the earth horizon and heading, and this is represented by another set of angles, "yaw," "pitch" and "roll" which angles match their colloquial meaning, but also have formal definition as an Euler sequence. These angles are the product of the rotational equations of motion, where orientation responds to torque, just as the velocity of a vehicle responds to forces. For all flight vehicles, these two sets of dynamics, rotational and translational, operate simultaneously and in a coupled fashion to evolve the vehicle's state (orientation and velocity) trajectory.
