Right or wrong

I am glad to find Harvard University Michael Sandel’s class videos “Justice: what’s the right thing to do?. It makes us meditate, it makes philosophy charming. Debates sharpen our wits. I suppose there is no right or wrong answer; it is a certain situation, a certain balance, a certain moment, and a certain justness by certain people. 


Educational Mission Chinese Students over 100 years ago

昨夜,偶尔看到这个五集的记录片幼童, 于是不能停下, 看到了半夜2点。今天查了一下, 原来是出自CCTV国家地理, 源于钱钢、胡劲草所著的书《留美幼童—中国最早的官派留学生》。一定是本好书, 能让我们从另外一个角度看中国近代历史的兴衰。

I came across this five-episode videos about the earliest Chinese students studying abroad on YouTube. It attracted me immediately. It tells me the Chinese history that was unavailable through traditional textbook when I studied in school. Quickly searched on Google, found a CEM Connections website and the book China’s First Hundred: Educational Mission Students in the United States. But I cannot find the English version of the original book by Qian Gang and Hu JinCao.

Optical Illusions

I found this interesting picture Ascending Staircase by chance. It reminds me a figure about “an architectural  impossibility” in Professor Ormrod’s book (2008) and what she (2008, p.198) said,

“The counstructive nature of perception allows us sometimes to be fooled in optical illusions.”

Also, another example about “an impossible object” displayed in Professor Ford’s book (2008, pp.363-364) is used to explain conceptual problem and conflicts within information retrieval.

In daily work, using these pictures as an analogy may help us to understand other’s assumptions and perspectives.
