Greatest Engineering Achievements of the 20th Century

In the last century, technology development grew exponentially, but this is impossible without ceramics. Below is a list of 20 engineering achievements (www.greatachievements.org/) of the National Academy of Engineering that will have the greatest impact on the quality of life in the 20th century and how ceramic materials can live for all humanity It shows how you can make it easier.

Scintillator for ultrasound diagnosis, X-ray computed tomography (CT scan), cancer treatment

Includes advanced ceramics with excellent wear resistance, corrosion resistance, high temperature resistance, high rigidity, high melting point, high compressive strength and hardness, and a wide range of electrical, magnetic and optical properties

This grid pulsates power from thousands of large scale power plants, pushing up the electronics in all directions. It is considered one of the biggest engineering achievements of the 20th century. Every year in the United States home owners and businesses consume over $ 360 billion in electricity. This is more than 2% of GDP from towns and cities, to repay owner of large scale power plant, transmission line stretched to remote location, and century old energy production way.

In February of this year, the NAE worked with the Engineering Experts Association to select the twentieth best engineering achievements of the 20th century. The main criterion of choice is not the technology "Gee Wis", but the result of improving the quality of life for people. The results prove the strength and prospects of the project. Looking back at the list, it is clear that our world will be a very different place if any of its elements are deleted - and not so warm and hospitality. This list covers a wide range of human efforts, from a wide range of grid networks (No. 1) to development of high-performance materials (No. 20). Advances between the two are all aspects of people's lives (Safe Water, No. 4 and Medical Technology, No. 16), people's way of working (computer, number 8 and phone number, 9), that people play I changed almost completely. Road (broadcasting, television, part 6), way people move (car, part 2, airplane, part 3)
