来自北京一零一中学的陈肇盟和陈启昭是一对孪生兄妹，他们非常可爱，但更富有智慧。在2012年8月23日(美国太平洋时间)结束的2011-2012年度斯坦福大学美国“数学大联盟杯赛”中学组决赛和数学夏令营 (Stanford Math League Summer Tournament) 中，哥哥陈肇盟以149分的优异成绩获得个人决赛八年级组金牌 (满分为150分)，妹妹陈启昭以一分之差 (148分)获得个人决赛八年级组银牌。兄妹俩平时一起上学、上课(都在理科试验班)，形影不离，即互相照应，又互相较着劲。妹妹陈启昭听说自己以一分之差输给哥哥获得银牌心里还很难过，后来获知自己还获得团体决赛八 - 九年级组金牌，很快又高兴了。他们取得的优异成绩和展现出的超人的才华令世界著名数学家、斯坦福大学终身教授Brian Conrad，美国“数学大联盟杯赛”创始人Daniel Flegler和Steve Conrad，著名数学奥林匹克专家、中国国际数学奥林匹克竞赛(IMO)泰斗裘宗沪先生，“华罗庚金杯”少年数学邀请赛主试委员会委员、美国“数学大联盟杯赛”(中国赛区)组委会执行副主任陶晓永等赞叹不已。兄妹俩对参加这次美国“数学大联盟杯赛”颇有感触：

“我们兄妹俩可以说从小就非常爱好数学，甚至可以说是痴迷数学，从小参加了很多国内的数学竞赛，获得很多奖，也算是久经沙场了。但这次参加这次美国‘数学大联盟杯赛’，还是让我们耳目一新，大开眼界。大联盟杯赛试题涉及面广，包括代数、几何、数论、组合等，题目新颖，富有趣味性和挑战性。我们想这和美国教育涉及面广、着重于激发学生的好奇心、独立思考、追求创新有关。这次给我们上课的斯坦福大学的教授有世界顶级的科学家，比如Brian Conrad, Dan Boneh, 和Ravi Vakil；有著名的斯坦福大学天才少年培养计划(Stanford University Education Program for Gifted Youth, EPGY)和斯坦福大学数学夏令营(Stanford University Mathematics Camp, SUMaC)的创始人Rafe Mazzeo 和Rick Sommer；还有把数学和艺术完美结合的Professor John Edmark等。让我们大开了眼界。

斯坦福的校园十分宁静幽美，附近尽是运动场所，校园中充斥着绿色的气息。绿草、平房、小车，一切和谐，一切自然。

进入我们入住的房间，我们再次感到洁净与别致，不大的房子里，用具十分齐全，透着古典的气息与现代交融。进行简单的整理后，我们开始campus tour。总的来说，欢乐、自由、绿色、和谐。

首日在欣喜与好奇中快速度过。

次日是我们的生日(8月21日)，没有父母的陪伴，略微感到一点遗憾。早晨，大家为我们唱起了生日歌，顿生一种温暖。

我们还体验了计算机在线智能学习系统的魅力。 决赛前三个月胡老师就让我们用美国“数学大联盟杯赛”在线智能学习系统来准备决赛。 我们体验了先进的计算机在线智能学习系统的魅力。 其中的知识点体系、解题方法体系、个性化作业、电子错题本、即时测评、遗忘曲线、成长记录、系统分析等功能让我们很欣喜和收益匪浅。 到美国后才知道美国学生大都使用在线智能学习系统进行学习，不过他们用的是英文的界面。”

Today (08/22/2012) is my third day at Stanford University Summer Camp. I had a fantastic time. We studied playing bridge and took some exams here. There is a group of students from America and another group from Canada. We didn't want to talk to them at first, because we were afraid of talking English. As time went on, we got to know each other well. We came here for learning math and English and making friends with others. We had Puzzle and Rubik's Cube class and the problems solving class. The most useful thing we learned is we have to think deeply about simple things and then we can know more. When I was thinking deeply, I found it's interesting when dealing with problem. We had fun and learned a lot of useful things here. This is the best summer camp I have ever had.

Dan,

Thanks again. You guys did a great job.

You are far beyond me on the math questions, but I think it was appropriate for the students you chose. Similarly, I think the choice of lecture topics gave a lot of background to these kids. The only thing that I might suggest is to have a couple more lectures on topics where math is “applied” to another field—economics/game theory, actuarial sciences, operations research, investing/risk, etc. Easy for me to suggest, but not as easy for you to execute, so feel free to use or discard these thoughts.

Also, there are some “summer camp fairs” where you may want to have a physical presence to let people know about the program—maybe by turning the schedule/pictures from this year into more of a brochure? It might also serve as another advertising vehicle for your contests.

Best Regards,
Brian

Hi Dan,

Thank you for all the courses and programs you organized this year at Stanford University. I had a really wonderful time at the program.

It has been a privilege for me to attend the final contest, I would wish to come back some day.

And especially thanks for all the books that you signed for me. They are also very special to me because of Steve's and your signature.

Would you say thanks to Steve for me?

Thank you again and see you some day!

From Patrick.

Dear Dan,

Wouldn't it be more fun if you hold next year's program in Beijing, China? That way, the participants from North America and from Europe will get a chance to explore China.

By the way, thanks for giving me a chance to visit the Stanford Campus. I had a great time there.

Best regards,
Amily
