Bull

A bull is an intact (i.e., not castrated) adult male of the species Bos taurus (cattle). More muscular and aggressive than the female of the species, the cow, the bull has long been an important symbol in many cultures, and plays a significant role in both beef and dairy farming, and in a variety of other cultural activities.

Nomenclature

The female counterpart to a bull is a cow, while a male of the species which has been castrated is a steer, ox or bullock, although in North America this last term refers to a young bull, and in Australia to a draught animal. Usage of these terms varies considerably with area and dialect. Colloquially, people unfamiliar with cattle may refer to both castrated and intact animals as "bulls".

A wild, young, unmarked bull is known as a micky in Australia. Improper or late castration on a bull results in it becoming a coarse steer, also known as a stag in Australia, Canada and New Zealand. In some countries an incompletely castrated male is known also as a rig or ridgling.

2000

2000 (MM) was a century leap year starting on Saturday (dominical letter BA) of the Gregorian calendar, the 2000th year of the Common Era (CE) and Anno Domini (AD) designations, the 1000th and last year of the 2nd millennium, the 100th and last year of the 20th century, and the 1st year of the 2000s decade.

2000 was designated as:

Popular culture holds the year 2000 as the first year of the 21st century and the 3rd millennium due to a tendency of grouping the years according to decimal values, as if year zero were counted. According to the Gregorian Calendar, these distinctions fall to the year 2001 because the 1st century was retroactively said to start with year AD 1. Since the calendar does not have year zero, its first millennium spanned from years 1 to 1000 inclusively and its second millennium from years 1001 to 2000 (See more at Millennium).

The year 2000 is sometimes abbreviated as "Y2K" (the "Y" stands for "year", and the "K" stands for "kilo" which means "thousand"). The year 2000 was the subject of Y2K concerns, which are fears that computers would not shift from 1999 to 2000 correctly. However, by the end of 1999, many companies had already converted to new, or upgraded, existing software. Some even obtained Y2K certification. As a result of massive effort, relatively few problems occurred.
