自我意识 Self-Awareness Virginia Woolf/弗吉尼亚.吴尔夫 The man who is aware of himself is henceforth independent; and he is never bored, and life is only too short, and he is steeped through and through with profound yet temperate happiness. He alone lives, while other people, slaves of ceremony, let life slip past time in a kind of dream. Once conform, once do what other people do finer than they do it, and a lethargy steals over all the finer nerves and faculties of the soul, He becomes all outer show and inward emptiness; dull, callous, and indifferent. 凡是意识到自我的人从今往后才是独立的；他永远不知疲倦，他明白生命苦短，所以完全沉浸于深深的而又适度的幸福之中。
他独立生活，而别人是繁文缛节的奴隶，在醉生梦死之中听从生命悄然流逝。一旦循规蹈矩，一旦人为亦为，呆滞就笼罩着灵魂中一切灵敏的神经和官能。
灵魂变得徒有其表，其中空空；迟钝，木然、冷漠。 Discovery Diane Ackerman/迪安.阿克曼 The word “discovery” literally means, uncovering something that's hidden from view. But what really happens is a change in the viewer. The familiar offers comfort few can resist, and fewer still want to disturb. But as relatively recent inventions such as the telescope and microscope have taught us, the unknown has many layers. Every truth has geological strata, and you can't have orthodoxy without a heresy. The moment a newborn opens its eyes, discovery begins. I learned this with a laugh one morning after delivering a calf. When it lifted up its fluffy head and looked at me, its eyes held the absolute bewilderment of the newly born. A moment before it had the even black nowhere of the womb, and suddenly its world was full of color, movement and noise. I've never seen anything so shocked to be alive. “发现”一词，字面上是指揭开某种视线以外的隐藏的事物。
不过其实是观察者自身发生了变化。很少人能抗拒熟悉事物带来的舒适，愿意扰乱这种舒适的人更少。
然而，正如望远镜、显微镜这些较为近期的发明所揭示给我们的，求知事物具有多种层次。每个事实都有地质层次，没有异端也就无所谓正统。
新生儿睁开双眼的那一刻起，发现也就开始了。我是在一天清晨给一头小牛犊接生的时候突然意识到这一点的，不禁大笑。
小牛仰起毛茸茸的脑袋看着我，目光中透出这个新生命对世界的一无所知。片刻这前，它还呆在母体里某个黑暗而平静的地方，突然，它的世界变得五光十色，变得活泼而喧闹。
我从未见过任何东西在获得生命时是如些的惊异。

Science drink milk little common sense 5Drinking milk is good for health, but many people drink milk in still exist a number of the error on the idea, this paper introduces some scientific drinking milk little common sense.The 1 morning fasting drink milk should not be.

In addition, big milk method is insufficient, because this will reduce in oral and salivary mixed opportunity, is not conducive to digestion and absorption.

Scientific studies found that, in the human body calcium metabolism will have a special rule: the evening especially midnight when the content of serum calcium, there will be a" trough", forcing the body through regulating mechanism of transport a portion of bone calcium supplement. In this way, calcium in the blood is temporarily maintained, but have reduced skeletal calcium in. Milk of calcium rich, therefore before bedtime drink a cup of milk, can compensate for human body needs calcium at night.3 milk should not be adding sugar boiling. Milk is rich in amino acids, in the condition of high temperature in the milk of lysine with sugars occurring Maillard reaction, generate a new compounds - fructosyl amino acid.

Does Technology Prevent Creativity?Thanks to Lowell Monke, I am getting rather critical about tools and technology supporting creativity. In many cases technology distracts our concentration, causes problems to our social network and interferes with our natural rhythm of life. Monke's "Breaking Down the Digital Walls" is an interesting book and I am looking forward to read the forthcoming book. In the meanwhile, please take a look at his thought-provoking article "The Human Touch" . Just to give you an example of Monke's thinking: "What 'Information Age' values tempt us to forget is that all of the information gushing through our electronic networks is abstract; that is, it is all representations, one or more symbolic steps removed from any concrete object or personal experience". Another wake-up call came, when I read an interesting report from National Science Foundation (NSF) workshop about Creativity Support Tools. There were some guidelines for these Creativity Support Tools introduced . To me they are like from an HCI manual and similar to Shneiderman's "Leonardo's Laptop: Human Needs and the New Computing Technologies" - you remember those 4-phases: Collect - Relate - Create - Donate.What bothers me is the concept "Social Creativity" described the report. This concept and the related research is to me very inconsistent, it is mostly based on communities-of-practice research, not creativity research. I noticed it already when I participated a social creativity session in the HCI International (UAHCI) conference in Las Vegas. 仅供参考。

Ever since they were first put on the market in the early 1990s, gentically mondified (GM， 转基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would ,is it the best solutiorr? Despite what it promiises,GM technology actually has not increased the production potential of any corp. In fact Studies show that the most crown GM croo. GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production. Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides（杀虫剂）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “ The promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition. At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report. As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.。
