Engineering from giant to tiny

by Weiyu Li

The engineering is in everywhere in our daily life. From the huge man-made island to the capsule micro robot, the engineering success happens everywhere every time.
The man-made island can be tracked back to 1522 AD. in Song Dynasty in China. Because of the tide, sometimes the islands were in the sea, sometimes they were under that. The uses of this kind ofman-made island were diverse. House or castles could be built on it for fishing or deliver the signals of the attacking enemies. Always, they were build by the simple way which was carrying the soil to the certain places.
Now days, the number of the man-made islands are much bigger than before. Some countries build dozens of man-made islands for many uses. Some man-made islands in Dubai are for the tourist trade, some of those in China are for the national defense and exploring the port. Japan, which has the largest area and the biggest number of the man-made islands build the island for the national airport because of the small size of the land and the jagged terrain.

To the capsule micro robot is not an old word to us. It appeared in the last decade, the idea proposed
by the scientists in China in 2008. They created a robot like this to reduce the pain the patients feel during the physical operations. Scientists wants a robot controlled by magnitude filed so this tiny robot can go through the blood vessels, reach and check the pathogenic site, solve the problem without cutting the skin. The theory successfully supported by a famous professor in a university and reported in a well-known scientific magazine in China.
