whirlwind,

revolving mass of air resulting from local atmospheric instability, such as that caused by intense heating of the ground by the sun on a hot summer day. Examples of whirlwinds are waterspoutswaterspout,
tornado occurring at sea or over inland waters. The characteristic funnel-shaped cloud is formed at the base of a cumulus-type cloud and extends downward to the water surface, where it picks up spray.

, tornadoestornado,
dark, funnel-shaped cloud containing violently rotating air that develops below a heavy cumulonimbus cloud mass and extends toward the earth. The funnel twists about, rises and falls, and where it reaches the earth causes great destruction.

What does it mean when you dream about a whirlwind?

To encounter a whirlwind in a dream may indicate that the dreamer has been on a whirlwind schedule. The force and power of a whirlwind might also indicate that the dreamer is being lifted up and placed on an entirely new life path.

whirlwind

a column of air whirling around and towards a more or less vertical axis of low pressure, which moves along the land or ocean surface

Whirlwind

(computer)
An early computer from the MIT Research Laboratory for Electronics.

Whirlwind used electrostatic memory and ran Laning and Zierler (1953); and ALGEBRAIC, COMPREHENSIVE and SUMMER SESSION (all 1959).

Whirlwind

The first electronic digital computer used in a real-time application and the first to use magnetic core memory. The Whirlwind was originally intended to be a general-purpose aircraft simulator for the U.S. Navy, but evolved into a general-purpose computer that became the prototype for the SAGE air defense system (see SAGE). Developed at the Massachusetts Institute of Technology, construction began in 1947. It became operational in the early 1950s.

Its first memory used electrostatic storage tubes that proved unreliable, and in 1953, magnetic core memory was added, dramatically improving performance and reliability. The Whirlwind used 2K words of core memory and magnetic drum and tape for storage. The machine was continually enhanced, eventually using 12,000 vacuum tubes and 20,000 diodes and occupying two floors of an MIT campus building.

Whirlwind's circuit design, core memory and use of CRTs contributed greatly in the making of future computers. Project members later worked on IBM's 700 series. One in particular, Kenneth Olsen, founded Digital Equipment Corporation.

Olsen worked on the Whirlwind and later pioneered the minicomputer industry with his PDP computer series. He founded and ran Digital Equipment Corporation for 35 years until his retirement in 1992. (Image courtesy of Digital Equipment Corporation.)
