Things I learn today

1. Ku Klux Klan (KKK)：这三个字原始字义是指手枪扳机时三步骤声响，为学习射击时的口诀。现在指美国恐怖主义秘密组织——3K党。3K党在美国史上有两个，一个成立于南北战争后不久，到19世纪’70年代消失；另一个创始于1951年乔治亚州亚特兰大城，活动至今。3K党的宗旨虽随时代改变而不尽一致，但基本上它反黑人、天主教徒及犹太人，并以恐怖暴力活动著称。An extremist right-wing secret society in the United States. The Ku Klux Klan was originally founded in the southern states after the Civil War to oppose social change and black emancipation by violence and terrorism. Although disbanded twice, it reemerged in the 1950s and 1960s and continues at a local level. Members disguise themselves in white robes and hoods, and often use a burning cross as a symbol of their organization.
2. Martin Luther (10 November 1483) vs Martin Luther King Jr.(15 January 1929)：前者是宗教改革的领袖和发起者，新教的创立者。German monk who started Protestant Reformation。
   后者是美国黑人民权运动的领袖，同时也是个浸信会的牧师。
3. Rosa Parks(1913 - 2005): A humble African-American seamstress in a department store changed the course of the American history when she refused to give up her bus seat to a white man. she was arrested and fined, and this incident led to the bus boycott in Montgomery and a series of other civil rights movements and resulted the abolishment of the segregation laws in the southern states of USA.
