Bit

A bit, also known as a Shannon, is the basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a 0or1. The term bit is a portmanteau of binary digit.

The two values can also be interpreted as logical values (true/false, yes/no), algebraic signs (+/−), activation states (on/off), or any other two-valued attribute. The correspondence between these values and the physical states of the underlying storage or device is a matter of convention, and different assignments may be used even within the same device or program. The length of a binary number may be referred to as its bit-length.

In information theory, one bit is typically defined as the uncertainty of a binary random variable that is 0 or 1 with equal probability, or the information that is gained when the value of such a variable becomes known.

In quantum computing, a quantum bit or qubit is a quantum system that can exist in superposition of two classical (i.e., non-quantum) bit values.

James May

James Daniel May (born 16 January 1963) is a British television presenter and journalist. He is widely known for his years as a co-presenter of the motoring programme Top Gear alongside Jeremy Clarkson and Richard Hammond from 2003 to 2015. As of 2016 he was a director of the production company W. Chump & Sons and scheduled to be presenting an Untitled Amazon motoring show for Amazon Video as an exclusive for Amazon Prime customers, alongside his former Top Gear co-hosts.

May has presented other programmes on themes including science and technology, toys, wine culture, and the plight of manliness in modern times. He wrote a weekly column for The Daily Telegraph's motoring section from 2003 to 2011.

Early life

James May was born in Bristol, one of four children; he has two sisters and a brother. May attended Caerleon Endowed Junior School in Newport. He spent his teenage years in South Yorkshire where he attended Oakwood Comprehensive School in Rotherham and was a choirboy at Whiston Parish Church. He was also at school with Life on Mars and Ashes to Ashes star Dean Andrews.

Danica McKellar

Danica Mae McKellar (born January 3, 1975) is an American actress, author, mathematician, and education advocate. She played Kevin Arnold's on-off girlfriend Winnie Cooper in the television series The Wonder Years, and later wrote four non-fiction books: Math Doesn't Suck, Kiss My Math, Hot X: Algebra Exposed and Girls Get Curves: Geometry Takes Shape, which encourage middle-school and high-school girls to have confidence and succeed in mathematics.

Early life

Born in La Jolla, California, McKellar moved with her family to Los Angeles when she was eight. Her mother Mahalia was a homemaker; her father Christopher is a real estate developer. Her mother's ancestry is Portuguese (via the Azores and Madeira islands); her father's ancestry is Scottish, Irish, French, German, and Dutch.

Danica and her sister Crystal McKellar both maintained professional acting careers as children, but with a strong emphasis on education as a priority. As a result, Crystal became a corporate lawyer, while Danica majored in mathematics. Danica and Crystal also have two half-brothers, Chris Junior and Connor McKellar.
