In the history of cryptography, the Enigma was a portable cipher machine used to encrypt and decrypt secret messages. More precisely, Enigma was a family of related electro-mechanical rotor machines — there were a variety of different models.

The Enigma was used commercially from the early 1920s on, and was also adopted by the military and governmental services of a number of nations — most famously by Nazi Germany before and during World War II.

The Los Angeles Sports Arena is an indoor arena in Los Angeles, California. Built by the city in 1959 at a cost of $7 million, the arena can seat 16,021 for ice hockey and 18,750 for basketball. The Sports Arena is located in Exposition Park, adjacent to the Los Angeles Memorial Coliseum and the University of Southern California.

Currently, high school basketball championships, concerts, and conventions are held in the facility. With the USC teams moving to the new Galen Center starting in the Fall of 2006, the Sports Arena is no longer the home court for any college or professional team.

The sports teams for UCLA are called the Bruins. The Bruin men's and womens' teams participate in NCAA Division I-A as part of the Pacific Ten Conference. Many of the greatest college athletes in history have played for UCLA. Jackie Robinson, Troy Aikman, Kareem Abdul-Jabbar, Earl Watson, and Ann Meyers are just some of the famous athletic alumni.

The UCLA school colors are "True Blue" and gold. The "True Blue" is a slightly darker shade than the previous powder blue worn by teams. The shade was developed by the UCLA athletic department and Adidas for the 2003 school year.

A skipper is a man who has command of a boat or ship. It is more or less equivalent to "captain". At sea he has absolute command over his men. He may or may not be the owner of the boat.

The word is derived from the Dutch word schipper; schip is Dutch for "ship". In Dutch sch- is pronounced [s-kh-] (not [sh] as in German), and English-speakers rendered this as [sk-].

The word "skipper" is used more than "captain" for some types of craft, for example trawlers.

In U.S. Navy slang, it is a term used in reference to the Commanding officer of any Ship, Unit, Platoon, or Detachment regardless of rank. It is generally only applied to someone who has earned the speaker's respect.
