U.S. Energy Secretary Steven Chu’s address at Harvard’s Afternoon Exercises

June 24th, 2009 admin No comments

Madam President Faust, members of the Harvard Corporation and the Board of Overseers, faculty, family, friends, and, most importantly, today’s graduates, thank you for letting me share this wonderful day with you.

I am not sure I can live up to the high standards of Harvard Commencement speakers. Last year, J.K. Rowling, the billionaire novelist, who started as a classics student, graced this podium. The year before, Bill Gates, the mega-billionaire philanthropist and computer nerd stood here. Today, sadly, you have me. I am not wealthy, but at least I am a nerd.

I am grateful to receive an honorary degree from Harvard, an honor that means more to me than you might care to imagine. You see, I was the academic black sheep of my family. My older brother has an M.D./Ph.D. from MIT and Harvard while my younger brother has a law degree from Harvard. When I was awarded a Nobel Prize, I thought my mother would be pleased. Not so. When I called her on the morning of the announcement, she replied, “That’s nice, but when are you going to visit me next.” Now, as the last brother with a degree from Harvard, maybe, at last, she will be satisfied.

Another difficulty with giving a Harvard commencement address is that some of you may disapprove of the fact that I have borrowed material from previous speeches. I ask that you forgive me for two reasons.

First, in order to have impact, it is important to deliver the same message more than once. In science, it is important to be the first person to make a discovery, but it is even more important to be the last person to make that discovery.

Second, authors who borrow from others are following in the footsteps of the best. Ralph Waldo Emerson, who graduated from Harvard at the age of 18, noted “All my best thoughts were stolen by the ancients.” Picasso declared “Good artists borrow. Great artists steal.” Why should commencement speakers be held to a higher standard?

熄灯一小时 爱护地球从点滴做起

March 27th, 2009 admin No comments

在明天(3月28日)晚上20:30——31:30是今年第一次“熄灯一小时”活动时间。希望我们也参与进来,在当时关闭自己房间的灯光,为减少光污染、为地球健康尽一点微薄之力。

“地球一小时”(又称熄灯一小时)是世界自然基金会应对全球气候变化所提出的一项倡议,希望个人、社区、企业和政府在特定的时间熄灯一小时,来表明他们对应对气候变化行动的支持。如今该活动已经演变成国际性环保活动。

2009年恰逢国际天文年,今年的“地球一小时”侧重减少光污染、暗夜保护等内容,让大家都来参与数星星,认星星,提醒大家注意光污染。今年熄灯活动计划有三次:第一次是在3月28日,由世界自然基金会发起对抗气候变化的集体行动,活动时间北京时间晚8时30分至9时30分,号召人们在这一个小时里熄灭电灯、关闭电源。第二次活动在6月21日,当天是夏至日,也是夏季用电高峰期的开始,当晚亚洲多个城市的地标性建筑将熄灯一小时。第三次活动安排在七夕节前夕的8月22日,七夕节是我国的传统节日,同时日、韩等亚洲国家也有过七夕的传统,将在熄灯间隙组织认星和观星活动。

傻狗有傻福

作者                 星 竹

曾经养过一只很特别的狗——以色列沙皮狗。狗是从宠物园抱来的,老板说,以色列沙皮狗很聪明,不过因为它过分聪明,你不一定能养得活。这话让我起了挑战心,于是,我偏偏抱回来一只。

小狗只有两个月大,刚抱回来时竟然拒绝吃东西,整夜都睁着眼睛,警觉地注视着周围的一切。一点风吹草动它就会紧张万分,躁动不安地用牙齿撕扯着给它的一只小枕头。

抱来半个月了,它依然对人十分冷淡,像是患了孤独症。起初我以为它得了病,回去问老板。老板给我一本介绍狗的书,翻到以色列沙皮狗那一页,我吓了一跳,书中这样描绘:“以色列沙皮狗,因为绝顶聪明,而非常多疑,甚至会陷入深深的忧郁。生人喂食一律不吃,新的环境它一定不睡,一生只能居住在一个环境里,并且只跟定一个主人……因此存活率很低。世界上多用于军事侦察……”

养蚯蚓清厨余垃圾

蚯蚓粪可换有机蔬菜 宣武区后天开始试点

3月4日,宣武椿树园社区的20户居民家里将迎来一种新的“宠物”——蚯蚓。这些软乎乎的可爱的小家伙能帮助消化家里的剩饭剩菜、垃圾果皮甚至是宠物的粪便,相关机构还将定期到居民家中以有机蔬菜回收蚯蚓和蚯蚓粪便,放到耕地中,分解其中的垃圾和重金属,使土地重新变得肥沃。

厨余垃圾是蚯蚓美食

“养2000条蚯蚓就可吃掉一个家庭一天产生的厨余垃圾。”中国志愿者第五波社区志愿服务总队队长韩百胜老师说,蚯蚓在环保和垃圾减量方面可以说是“贡献卓著”,而饲养蚯蚓的“饲料”就是家中的厨余垃圾。

韩老师给记者算了一笔账,一条蚯蚓可以在24小时内分解和自己体重相同的垃圾,2000条蚯蚓的“体重”是一公斤,以一个3口之家每天产生一公斤厨余垃圾计算,2000条蚯蚓一天内就能把垃圾全部吃掉。”蚯蚓甚至可以解决困扰城市已久的宠物粪便问题。“因为小狗的粪便也是蚯蚓的美食。”
