Passage: Jiang Ji (died 18 May 249), courtesy name Zitong, was an official and military general of the state of Cao Wei during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Jiang Ji started his career as a low-level official in his native Yang Province before becoming a subordinate of Cao Cao, the warlord who controlled the central government towards the end of the Eastern Han dynasty. After the end of the Eastern Han dynasty, he served in the state of Cao Wei through the reigns of the first three emperors – Cao Pi, Cao Rui and Cao Fang – and held various appointments in the military before rising to Grand Commandant, one of the top positions in the central government. During his service in Wei, he was known for being candid in giving advice to the emperor on various issues, including consolidating power, halting labour-intensive construction projects, and officials' abuses of power. In February 249, he joined the regent Sima Yi in staging a successful coup d'état against his co-regent Cao Shuang, but died from illness a few months later.

Passage: The Lakers opened the series with a 115–109 victory at the Boston Garden. In Game 2, the Lakers led 113–111 with 18 seconds left when Gerald Henderson stole a James Worthy pass to score a game tying layup and the Celtics eventually prevailed in overtime 124–121. In Game 3, the Lakers raced to an easy 137–104 victory as Magic Johnson dished out 21 assists. After the game, Larry Bird said his team played like "sissies" in an attempt to light a fire under his teammates. In Game 4, the Lakers had a five-point game lead with less than a minute to play, but made several execution errors as the Celtics tied the game and then came away with a 129–125 victory in overtime. The game was also marked by Celtic forward Kevin McHale's takedown of Laker forward Kurt Rambis on a breakaway layup which triggered the physical aspect of the rivalry. Kareem Abdul-Jabbar would go after Larry Bird later on in the third quarter, and 1981 Finals MVP Cedric Maxwell further antagonized the Lakers by following a missed James Worthy free throw by crossing the lane with his hands around his own neck, symbolizing that Worthy was "choking" under pressure. In Game 5, the Celtics took a 3–2 series lead as Larry Bird scored 34 points. The game was known as the "Heat Game", as it was played under 97 °F-heat, and without any air conditioning at the infamous Boston Garden. In Game 6, the Lakers evened the series with a 119–108 victory. In the game, the Lakers answered the Celtics rough tactics when Worthy shoved Cedric Maxwell into a basket support. After the game, a Laker fan threw a beer at Celtics guard M.L. Carr as he left the floor, causing him to label the series "all-out-war." In Game 7, the Celtics were led by Cedric Maxwell, who had 24 points, eight rebounds, and eight assists as they came away with a 111–102 victory. In the game the Lakers rallied from a 14-point deficit to three points down with one minute remaining, when Maxwell knocked the ball away from Magic Johnson. Dennis Johnson responded by sinking two free throws to seal the Celtics' victory. Larry Bird was named MVP of the series.

Lyne writes that he is "mostly interested in finding and understanding radio pulsars in all their various forms and with their various companions. Presently, I am most occupied with the development of new multibeam search systems at Jodrell and Parkes, in order to probe deeper into the Galaxy, particularly for millisecond pulsars, young pulsars and any that might be in binary systems."
