Yoyo (other)
A yo-yo (also spelled yoyo) is a toy consisting of an axle connected to two cylinder, disks, and a string looped around the axle, similar to a wikt:spool, spool. It is an ancient toy with proof of existence since 500 BCE. The yo-yo was also called a bandalore in the 17th century. It is played by holding the free end of the string known as the handle (by inserting one fingerusually the middle or ring fingerinto a slip knot), allowing gravity (or the force of a throw and gravity) to spin the yo-yo and unwind the string (similar to how a pullstring works). The player then allows the yo-yo to wind itself back to the player's hand, exploiting its spin (and the associated rotational energy). This is often called "yo-yoing" or "playing yo-yo". In the simplest play, the string is intended to be wound on the spool by hand; the yo-yo is thrown downward, hits the end of the string then winds up the string toward the hand, and finally the yo-yo is grabbed, ready to be thrown again.

Before Christ
The terms (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term is Medieval Latin and means 'in the year of the Lord', but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "''anno Domini nostri Jesu Christi''", which translates to 'in the year of our Lord Jesus Christ'. The form "BC" is specific to English and equivalent abbreviations are used in other languages: the Latin form is but is rarely seen. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, ''AD'' counting years from the start of this epoch and ''BC'' denoting years before the start of the era. There is no year zero in this scheme; thus ''the year AD 1 immediately follows the year 1 BC''. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century. Traditionally, English follows Latin usage by placing the "AD" abbr ...
