Length

In geometric measurements, length is the most extended dimension of an object. In the International System of Quantities, length is any quantity with dimension distance. In other contexts "length" is the measured dimension of an object. For example, it is possible to cut a length of a wire which is shorter than wire thickness.

Length may be distinguished from height, which is vertical extent, and width or breadth, which are the distance from side to side, measuring across the object at right angles to the length. Length is a measure of one dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed). In most systems of measurement, the unit of length is a base unit, from which other units are defined.

History

Measurement has been important ever since humans settled from nomadic lifestyles and started using building materials, occupying land and trading with neighbours. As society has become more technologically oriented, much higher accuracies of measurement are required in an increasingly diverse set of fields, from micro-electronics to interplanetary ranging.

Brock Lesnar

Brock Edward Lesnar (/ˈlɛznər/; born July 12, 1977) is an American professional wrestler and former amateur wrestler, professional American football player, and mixed martial artist. He is currently signed to WWE. Lesnar is a four-time WWE (World Heavyweight) Champion, a former UFC Heavyweight Champion, and an NCAA Division I Heavyweight Wrestling Champion, making him the only person to have won a WWE championship, UFC championship, and NCAA championship in a career.

After his successful amateur wrestling career at Bismarck State College and the University of Minnesota (106 victories and 5 losses), Lesnar signed with WWE (then the World Wrestling Federation) in 2000. He was assigned to its developmental promotion Ohio Valley Wrestling (OVW), where he was a three-time OVW Southern Tag Team Champion with Shelton Benjamin. After debuting on WWE's main roster in 2002, he won the WWE Championship on three separate occasions with victories over The Rock and Kurt Angle (twice). Lesnar won his first (Undisputed) WWE Championship five months after his main roster debut at the age of 25, becoming the youngest WWE Champion in history. He was also the 2002 King of the Ring and the 2003 Royal Rumble winner, making him the youngest King of the Ring and Royal Rumble winner as well. Following his match with Goldberg at WrestleMania XX, Lesnar left the WWE and pursued a career in the National Football League (NFL). He was named a defensive tackle for the Minnesota Vikings but was cut prior to the start of the 2004–05 season. In 2005, Lesnar returned to professional wrestling and signed with New Japan Pro Wrestling (NJPW), where he won the IWGP Heavyweight Championship in his first match. After a contractual dispute with NJPW, he also wrestled as IWGP Heavyweight Champion in the Inoki Genome Federation (IGF).
