Although it would be impossible to do this on earth, you actually could do this on the moon. The moon has a cold core and it also doesn’t have any oceans or groundwater to mess things up. In addition, the moon has no atmosphere, so the tunnel would have a nice vacuum in it that [...]

The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around.

This tiny, near-microscopic water flea has more genes than you. In fact, this freshwater zooplankton is the first crustacean to have its genome sequenced, and its 31,000 genes crowns it the animal with the most genes so far. For those keeping count at home, the average human has about 20,000 to 25,000 genes.

Concrete washbasin shaped as a fossil, the Ammonite washbasin from HighTech. Inspired by the archaic beauty of ammonites, this unique design showcases the organic qualities of concrete.

Below you’ll find animated diagrams and explanations of how various mechanisms work. Some of these have been crucial to major evolutions in mechanisms and technology, and allow us to do anything from fire weaponry to make cars move with the press of a pedal. Mechanical engineering is a complex and beneficial discipline, and this is [...]

Almost 100 years ago, Frank Morley proved a curious theorem from elementary geometry that unbelievably remained unknown until 1899. With time, the theorem became known in mathematical folklore as Morley’s Miracle (Morley’s Trisector Theorem is a more mundane term.) The theorem states that The three points of intersection of the adjacent trisectors of the angles [...]

有了Kindle DX， iPhone 4G 发现我电脑里的书开始不够了。实际上这两device都可以读pdf的，可是ePub的文档在这些device上使用的效果更好。特别当屏幕比较小的情况下，ePub可以自动根据屏幕大小重新排版。这样看起来就不像pdf那样要zoom in了。Amit Agarwal曾经有介绍ePub格式。我收集了以下下载书的网站，基本都提供ePub、mobi格式电子书下载。支持iBooks，Kindle，Stanza等阅读器！
