Changed by Liu Cixin's science book The Three-Body Problem, the show is very popular with people. One of the most exciting parts must be Operation Guzheng(“古筝行动”). In order to find the important information on a huge ship, people plan to cut the ship into pieces. They set up many thin strings(线) across the river, which are made by high technology. Looking like Guzheng, the strings quietly cut the steel ship into pieces as if the ship was soft tofu! 5 Is it possible to cut ships with thin strings in real life?In fact, strings are very good at cutting. For example, the egg cutting machine uses thin strings to cut eggs into pieces. A kite line can easily hurt people if it gets circle around their necks. This is because the thin strings have a very small contact area(接触面积), leading to a high intensity of pressure(压强) when they cut things. In the program, the strings are as thin as human hair. To cut the ship, the pressure needs to be 200 MPa(兆帕斯卡, 压强单位). How strong is that pressure? Imagine an elephant standing on a string! In real life, scientists won't be able to make such thin strings that wouldn't easily break at least in recent years. The cutting will also create lots of heat. We don't have the things to bear that high temperature while
