Why the Coronavirus is far more infectious than SARS?

To say that this new virus is far more infectious than SARS is based on the following three facts:

First, the infected person does not have any symptoms during the incubation period of 10-14 days. Currently, airports, stations, and terminals are all measured with fever, but most of them are ineffective. This is why a city such as Shanghai, which is extremely well guarded against high fever persons, but there still emerge a large number of confirmed and suspected patients.

Second, and equally frightening is that this latent virus carrier does not have any symptoms himself and don't develop, but it is highly contagious. 

Third, the virus is not only transmitted through breathing, but may also be transmitted from the eyes by close contact with people who carry the virus. Therefore, strictly speaking, the tightest protection is not only wearing a mask, but also goggles. However, in fact, very few people in the hospital waiting for a crowded consultation are wearing goggles.

We may be able to produce plastic with carbon dioxide someday

Due to the overuse of humans, there are now about 8 billion tons of plastic waste piled up on the surface and in the ocean. It is no wonder that plastics have been in poor reputation in recent years. But the importance of plastic is also unquestionable. The invention of plastic revolutionized life in the 20th century. It is durable, versatile, and hygienic. Such materials are almost non-existent in nature. If there is no plastic, we will never create records, tapes, film, etc. Naturally, we will not be able to record music, film, or develop modern medicine. Auto parts, light aircraft materials, satellites and spacecraft also rely on plastics, and global travel and space exploration are possible, not to mention computers, mobile phones and a wide range of networking technologies. Look around, if there is no plastic, our life will be difficult. Despite the importance of plastics, the disposal of plastics has always been a tricky issue. Not only that, but the source of plastic is...

《菊与刀》――解读日本人

第一章 任务―研究日本 由在美国曾经全力以赴与之战斗的敌人中，日本人的脾气是最琢磨不透的。这个强大对手，其行动和思维习惯竞与我们如此迥然不同，以至我们必须认真加以对待，这种情况在其他战争中是没有的。我们正如前此1905年的沙俄一样，作战的对手是一个不属于西方文化传统、而又充分武装和经过训练的民族。西方国家所公认的那些基于人性的战争惯例，对日本人显然是不存在的。这就使得太平洋上的战争不仅是一系列岛屿登陆作战和困难卓绝的后勤工作问题，从而使了解"敌性"成为一个主要问题。为了与之对抗，我们就必须了解他们的行动。 困难是巨大的。自从日本锁国的大门被打开以来的七十五年间，对日本人的描述总是使用一系列令人极为迷惑的"但是，又……"之类的词句，远非对世界其他民族的描述可比。一个严肃的观察家在论及其他非日本民族时，是不大会既说他们彬彬有礼，又加上一句说："但是，他们又很蛮横、倔傲。"他也不会既说该民族无比顽固，又说："但是，他们又极易适应激烈的革新"；也不会既说该民族性格温顺，又说他们不轻易服从上级的控制；也不会既说他们忠诚、宽厚，又宣称："但是他们又心存叛逆，满腹怨恨"；也不会既说他们勇敢成性，又描述他们如何怯懦；也不会既说他们的行动完全出自考虑别人的评价，即自己的面子，又说他们具有真诚的善良倾慕西方文化，又渲染他们顽固的保守主义。他不会既写一本书讲这个民族如何普遍爱美，如何对演员和艺术家给予崇高荣誉，如何醉心于菊花栽培，又另外写一本书来补充说，该民族崇尚刀剑和武土的无尚荣誉。 然而，所有上述这些矛盾却成为有关日本论著中纵横交织的经纬。而且，都是千真万确。刀与菊，两者都是一幅绘画的组成部分。日本人生性极其好斗而又非常温和；黩武而又爱美；倔傲自尊而又彬彬有礼；顽梗不化而又柔弱善变；驯服而又不愿受人摆布；忠贞而又易于叛变；勇敢而又懦怯；保守而又十分欢迎新的生活方式。他们十分介意别人对自己的行为的观感，但当别人对其劣迹毫无所知时，又会被罪恶所征服。他们的军队受到彻底的训练，却又具有反抗性。 了解日本既已成为美国的当务之急，我们就不能对这些矛盾以及其他许多同样令人烦躁的矛盾置之不理了。严重的事态接二连三地出现在我们面前。日本人下一步将采取什么行动？能否不进攻日本本土而获致投降？我们是否应该...
