第一束质子成功绕行LHC一周后,ATLAS和CMS立刻展示了它们所探测到的事件。当然今天的运行只有一束质子,所以并没有真正的碰撞产物。在point1的ATLAS control room 是LHC最引人注目的地方,这里几乎成了旅游景点。下午4时左右,我也亲自莅临ATLAS control room看望在这里监视LHC运行的干部职工:
On the first day ever of classes at the University of Chicago in 1892, President William Rainey Harper declared that there should be no particular celebration of the event, saying that the first day should go on as if the university had existed for a thousand years already. And so I feel about the LHC. Tomorrow will of course be a milestone in the history of the project, but let us keep in mind that this is not all about one day. Two decades of effort by thousands of people have preceded it, and the first circulation of beam can be viewed as just one more evolutionary step in that context. And like Churchill said, this is not the end, or even the beginning of the end — it’s only the end of the beginning. What comes next, after our friends in the press have left and the Champagne bottles have been drained, is what we all really signed on for: the scientific discoveries that, over the next decade, are going to change our understanding of how the universe works. At the University of Chicago’s decennial celebration in 1901, Harper said, “In these modern times ten years count for as much as one hundred years did formerly.” I think we’ll be saying the same thing in 2018.
今天,中国不但能够派出运动员参加奥运会,而且能够派出世界上人数最多的体育代表团,夺取奥运金牌榜的首位,而这样的成绩则是在北京举办的奥运会上获得的。然而一百年过去,竞技体育的成绩并不能掩盖中国在科技文化上的落后现实。科学技术是第一生产力,而先进生产力是先进文化的基础。中国要想摆脱现在综合国力落后的现状,根本的解决之道在于提高科学技术水平,以先进的生产力夺取21世纪国际竞争的优势。今天我以University of Wisconsin-Madison的学生的身份,拿着美国能源部的经费供给工资,见证欧洲(和美国)主导下的最昂贵、最复杂、最庞大的科学工程运行,其实未尝不是另一种旁观者。
現 在美國民主黨總統提名人的爭奪進入了最激烈的時候,而不久之前發生了一件事情:在初選中領先的伊利諾伊州聯邦參議員奧巴馬(Sen. Barack Obama, D-Illinois)陷入了一場涉及種族問題的爭論。奧巴馬的牧師賴特(Reverend Wright)在教堂里多次發表“反美”演講的 視頻被人貼到Youtube上,這位對奧巴馬影響甚深的牧師指責美國是一個被富有的白人控制的國家,指責美國支持以色列屠殺巴勒斯坦人,指責美國早期的黑 奴貿易,並且在教堂里瘋狂地高呼“’God Bless America.’ No, no, no, God damn America, that’s in the Bible for killing innocent people”。
在這樣的背景下,奧巴馬,週二早上在美國革命的勝地,費城,發表了“A More Perfect Union” 的演說,這個演說當即在美國引起轟動,甚至被認為它將成為美國歷史上最偉大的演說之一。在重申了他對賴特的反美言論的不贊同輿譴責後,奧巴馬並沒有像人們 想的那樣輿賴特做徹底的“切割”來顯示自己對美國主流的價值的認同,他向人們講述了他所接觸到賴特,一個把他介紹入基督教、一個向人們宣傳愛輿奉獻、向無 家可歸者提供幫助的牧師,一個曾經為美國海軍效力的賴特。他拒絕輿賴特切割,他說:”I can no more disown him than I can disown the black community. I can no more disown him than I can disown my white grandmother.”
甭管富人还是一般人,美国大部分家庭住在独门独院的house里。但是比house更普及的是汽车,就算是住在apartment的人也大都会有自己的汽车。所以Carolina Apartments还有地下车库,而且车库还容不下所有居民的汽车。在Madison,停车是一个问题。除非节假日和晚上,你想在UW的校园里找到一个车位是很困难的。为了解决这个问题,UW给每个学生、老师都发了一张bus pass,可以免费乘坐Madison Metro Bus的所有线路。因此,大部分老师、学生到学校去,都依赖Madison的公共汽车。
EVENT: Scientists from the U.S. Department of Energy's Brookhaven National Laboratory and the Relativistic Heavy Ion Collider (RHIC), the world's largest particle accelerator dedicated to nuclear physics research, will present compelling new findings about the nature of the "perfect" liquid created in near-light-speed collisions of gold i […]
