There are so many calculations/divisions/guesses/conjectures on who has made the biggest contribution to solve the problem or how much value the Chinese mathematicians has contributed to the final solution, after the news Chinese mathematicians put final pieces in global puzzle – Poincare conjecture came out. This is a metaphor. Funny. A Stage Play of the…
最近丘成桐先生宣布在美、俄等国科学家的工作基础上，中山大学朱熹平教授和旅美数学家、清华大学兼职教授曹怀东彻底证明了庞加莱猜想。（见Chinese mathematicians put final pieces in global puzzle – Poincare conjecture） 这一消息在很多中文论坛上都引起了的广泛的讨论，而在万维网上的教育与学术论坛上引起激烈的争论。 关于这个证明的正确与否有些人认为丘先生说的不能算。庞加莱猜想是个世界性的数学难题，世界上还有很多的研究小组在做。朱教授与曹教授的这个证明正确、完整与否都会有个定论的，只是时间问题而已。但这个定论绝对不是能在这些网上如此争论可以得出来的。 这些争论的另一焦点是朱教授与曹教授在这个证明上到底有多少贡献。这个问题也许不是时间能解决的。看看微积分这个数学方法，几百年了，还有人在争论到底是牛顿还是莱布尼兹的贡献大。但无论如何只要朱教授与曹教授的这个证明是正确、完整的，那就是对解决庞加莱猜想这个千年难题有贡献。 其实这些争论在很大程度上是田刚丘成桐事件（有人称为丘－田之争）的延续。 田刚丘成桐事件涉及到关于学术风气，选中国院士，长江特聘教授，大学科研经费的申请等等很多热点问题，而且这事件中的学校很多是中国甚至世界顶尖的学府，当中的人物很多都是成名的数学家。 以下关于这个事件的概要是从Wikipedia.org上找到的。我希望能用一、两个星期的时间补充一些细节及资料。
ASEAN’s labor could help China’ Pearl River delta solve the labor shortage problem, Zaobao reports. Some interesting figures: Vietnam’s production cost is 15-30% lower than China’s. To start up a garment factory with one thousand employee, it takes 6-7 million HK dolor investment in Vietnam; while it needs a few times more investment in China….
Today is a special day. It has been 17 years already. Here comes an interesting news. Two Chinese mathematicians, Professor Cao Huaidong, of Lehigh University in Pennsylvania, and Professor Zhu Xiping, of Zhongshan (Sun Yat-sen) University in south China’s Guangdong Province put the finishing touches to the complete proof of the Poincare Conjecture, which had…
A homesick Singapore exchange student was getting some bad time in Xi’an and posted some explicitive laden negative complains on her blog. These entries were cross-posted in Tianya.cn. It spurred a (small) uproar on Chinese internet. Many people have this view on Tomorrow.sg – a Singapore meta blog, another place the home sick girl was…
