October 25 枫叶熟了 正午时分，走出Lash Miller的殿门，一眼瞥见了一串枫叶。个头不大，大概因为换季的原因，却将整个由绿到黄的渐进色全部展现出来。浓浓仲秋的多伦多午后暖暖的日光下，间或的清风拂过，枫叶也俏皮地摇曳着。正下方，稀稀落落的光影也相应的变换着。
大概是感冒还没有完全好，固然是暖暖的午后，头疼还是隐约地发作，本是一副无精打采的状态，却有些奇怪地被这几片小小的枫叶所吸引，饶有兴趣地品味了半天。论个头，这几片叶子还不过是雏形，颜色也不是均一的红通通的那斑层林尽染，而且不过孤零零地立在那里……
寻觅之间，偶尔看到熊熊的校内，依然是原来28楼与31楼最后那个秋天，依然是屋角不起眼的那丛银杏叶……
原来就是那个住了四年的地方，转角处，不起眼的银杏叶子却早就深深地扎根在心灵的某个角落上。
记得原来十三就对两楼间的银杏叶颇为在乎，依稀记得毕业前夕她不无伤感地谈到那金色的银杏叶子的失落；熊熊果然是未雨绸缪，这个时候，在看那些银杏叶的影子，实在是太有杀伤力了。
又是一年秋时分，枫叶熟了 October 21 诺贝尔化学奖2007：固体表面的物理化学2007年诺贝尔化学奖由德国马普协会的Fritz-Haber研究所的Gerhard Ertl博士获得，奖励他在固体表面化学过程研究上的贡献。 2007诺贝尔化学奖网页链接：http://nobelprize.org/nobel_prizes/chemistry/laureates/2007/index.html 事前人们纷纷猜测今年的诺贝尔化学奖可能又是奖励生物化学方面的贡献。表面化学是地道的物理化学和化学物理，它的应用背景主要是和我们的生活密不可分的催化工业和半导体工业。在过去107年中，物理化学和化学物理领域的研究获得诺贝尔化学奖的数目超过总数的一半以上，现在又多添了一个。 中国在化学领域方面的研究中，物理化学和化学物理领域的基础研究相对来讲更为薄弱，因为国内普遍未能认识到物理化学和化学物理的基础研究在能源、材料和高技术以及军事国防等产业领域以及社会可持续发展中的重要作用。和国际上相比，我国在固体表面化学过程的基础研究方面尤为薄弱。近些年，我曾经写过一些东西来论述和呼吁物理化学和化学物理研究的重要性，希望大家充分认识到物理化学和化学物理是真正的强国的科学。不知道能否起到一点微弱的作用。 请参阅2001年我对中国化学和物理化学的一个评论：NatureComments.pdf 请参阅2005年我和杨俊林博士为《化学学科进展》写的第五章《物理化学进展》：物理化学进展.pdf 2005年国家自然科学基金委员会化学科学部组织编写的《化学学科进展》一书介绍和信息链接： http://www.china-pub.com/computers/common/info.asp?id=567279 我的研究领域是表面/界面物理化学，不过我对Ertl的固体表面化学研究并不内行。我的研究侧重的是液体，材料和生物界面，所采用的方法、概念、手段和理论和固体表面化学研究都颇为不同。 北京大学化学学院的吴凯教授和大连化学物理研究所的包信和研究员1990年代前后都在Ertl做所长的Fritz-Haber研究所做过数年的博士后研究，他们应该了解更多。遗憾的是他们去得有点晚，所以Nobel委员会列出的Ertl的25篇论文中他们的名字都没有出现。 据一般的小道消息，国际上不少人对固体表面化学反应领域是否在这个阶段能够得到诺贝尔奖的肯定有保留意见。而今年的固体表面化学反应的诺贝尔奖只给了Ertl一个人，估计会引起一些异议。1999年的飞秒化学诺贝尔奖也只给了Zewail教授一个人。国际上普遍认为这两个领域都不是哪一个人或哪一个小组具有完全领先的贡献。 美国加州大学Berkeley分校的Gabor Somorjai教授就是固体表面化学反应研究领域中获得诺贝尔奖呼声很高的科学家之一。前不久的北京诺贝尔峰会还专门邀请了Somorjai教授前来演讲和报告，他获得过Wolf奖和美国国家科学奖，他的影响其实早已超过一般诺贝尔奖获得者。1998年的Wolf化学奖，就是Gerhard Ertl和Gabor A. Somorjai二人合得的。小道消息说，Somorjai教授最近些年每年都在等诺贝尔委员会的电话，可以肯定的是明年他不用等了。 Gabor Somorjai教授的网页链接：http://chem.berkeley.edu/people/faculty/somorjai/somorjai.html 我留心了一下诺贝尔委员会的颁奖材料，其中特别提到Ertl的研究相对来讲更彻底和透彻，恐怕就是在用来堵其他人的嘴的。固体表面研究非常复杂，研究中经常会出错误的结果。Ertl的研究更为系统，unforced error更少，肯定比Somorjai教授要少，应该是Ertl胜出他人的一个重要因素。 不管怎么说，Ertl获得2007年的诺贝尔化学奖，是表面物理化学和化学物理领域自1932年Irving Langmuir获得诺贝尔化学奖之后的第二个诺贝尔奖，作为一个研究表面/界面的物理化学和化学物理学家，我很高兴。 zz行看热闹，内行看门道：诺贝尔化学奖2007之Ertl PK Somorjai篇

i dont have any religious belief so far October 11 Gerhard Ertl : The Nobel Prize in Chemistry 2007 for surface ChemistryThe Nobel Prize in Chemistry 2007"for his studies of chemical processes on solid surfaces"
October 02 Fuck off: CHM 151 DemoWhen I stepped into the 151 Lab this afternoon as an organic TA, I was a bit surprised to take the file from the head TA without any further explanations. Based on the experience I had as 139 TA, I was taking this similar but it turned out to be a huge mistake. When I was about to talk the lab a bit beforehand after putting some necessary materials on the board, the head TA used his low voice with the louderspeaker:"Time is up, TA starts distributing quizes"....Considering my students had not settle down, it was really tough to ask them to do a quiz right away. What is more? The way the head TA announced the start of the quiz really made me unpleasant because I was acting as a robt that could only follow commands of human being. After the quiz, I was right in the talk of this experiment in order to give the students some idea of the experiment. The head TA showed up all of a sudden and shouted to my students:"time is limit and you should start reflux now..." I was angry about that coz I was in the last several minutes of my talk and hadnt gone through the equipment and chemicals distributions. Now what a mess!!! The students rushed to the other side of the room to take chemicals in need but they didnt have any glassware in hands. While I was busy taking a look at this side, some students went to the other side of the room to pick up some glasswares without any idea what they needed... It took me more than 30 min to get everyone's reaction starting. When I was able to relax myself a bit, one student talked to me:"sir, i have got to go...the head TA kicks me off coz he didnt think I am prepared enough" and he disapppeared afterwards....The decision turned out to be based on the fact that this student could get a passing score of the quiz. What a ridiculous way!!!! And how could he treat the first year student this way...I mean the quiz itself had nothing to do with the practical experimental performance but theoretical stuff. Even if a student could not answer the questions, it didnt mean this student is not able to do experiment. Moreover, I was feeling offended coz they were my students and its my job to mark the quizes and evaluate my students. Since he was the head TA, he totally had the right to make this decision. In the term of politeness, he should at least talk to me or let me know in person rather than asking the students to say goodbye to me. In the reality, I could do nothing but watching the poor boy walking out. Then the head TA started the safety issue movie, which is obviously necessary. But I have to say he picked up the wrong time. It was around the time to end the reaction. Because the projector at my side was broken, all my students had to go to the other side to watch the movie, which resulted in the fact that two of my students overheated their samples. Whose fault was this? Why couldnt he start the movie at the very beginning to let students settle down? Why he couldnt ake all other TAs in the room to check the process of the experiment before he started the movie. Later he just walked into different demo group on his own and forced students to get together talking about last experiment without noticing the fact that some students were in the very critical point of their experiment. And all the TAs, I checked later, had some kind of feeling being ignored. The final results turned out to be that no one in all 4 groups could possibly manage the recrystallization part of the experiment and all TAs were complaining about the ridiculous experiment design. When I was done, and the head TA sudenlly showed up:"why didnt you return the datasheet to the students?" I was so angery but I tried to get myself calmed down and talked politely:"u didnt tell me abou that...and in other experiment, we used to keep a copy of the datasheet in our hand...""u should check with me first...i am the person in charge of this course and u should talk to ME...." I have no even a word to say with him then.....then he shouted to the girl TA in the other group close to me about the same problem. Well...it looked that I was not the only one to do so. Both the girl and I smiled to each other without any temper. I guess all the TAs had suffered a lot from that guy... When all TAs were done and got out of the lab room, it was 6:30....1:30 after the schedule and no one could even finish the expected experiment....Whose fault was this..... |
