10A The Science of Small
If you were to dig a hole 100 meters (300 feet) down from the center of the charming French village of Crozet, you`d find yourself in a strange, brightly lit tunnel three meters(ten feet) in diameter and 27 kilometers (17 miles) long, forming a perfect circle. Every few kilometers, the tunnel opens up into large rooms full of heavy steel structures, pipes, wires, magnets, and lots of other equipment.
Although workers and scientists sometimes ride bicycles around the tunnel, this is no traffic tunnel. It is the largest and most complicated scientific instrument ever built, and it was made with a simple but ambitious goal: to figure out what the universe is made of. Called the Large Hadron Collider (LHC), the machine sends particles zooming around its circle, moving near the speed of light At chosen points, these fast moving particles collide head on. Scientists can then analyze the collisions to get information about matter, energy, and the universe.
만약에 네가 Crozet의 매력적인 프랑스 마을의 중심으로부터 100미터(300피트) 구멍을 파 내려가면, 너는 스스로 이상한 것을 찾는다, 밝게 불이 켜지고 지름은 3미터(10 피트)에 27킬로미터(17마일)의 길이를 가지고, 완벽한 원의 모양을 한 터널을. 매 킬로미터마다, 터널은 중금속구조, 파이프, 와이어, 자석, 그리고 다른 많은 수의 다른 장치들로 가득 찬 큰 방으로 열린다.
