[00:02.70]Unit 20 New Frontiers 1
[00:06.15]Lesson 3 Scientific Breakthroughs
[00:10.11]PIONEERS OF SCIENCE
[00:12.16]In the summer of 1905,
[00:14.40]a young man was sitting at home
[00:15.97]after a day's work.
[00:18.04]While rocking his one-year-old baby,
[00:20.87]he thought something over.
[00:22.34]Suddenly, it came to him!
[00:24.80]The equation 2 "e=mc2" was born,
[00:28.78]an equation which would change
[00:30.44]our understanding of the universe
[00:32.31]but would also help to create the nuclear bomb.
[00:35.86]Albert Einstein was aware
[00:37.29]of recent developments,
[00:39.38]such as Marie Curie's research,
[00:42.33]but he had been working on his own.
[00:45.20]His world-famous equation showed
[00:47.12]how a small piece of mass could produce
[00:50.74]an unbelievable amount of energy.
[00:52.98]Einstein then showed
[00:54.47]in his "theory of relativity 3"
[00:56.35]that not even time, mass or length
[00:59.37]are constant - they change according
[01:02.05]to our experience of them.
[01:04.13]For example, if we could see people moving
[01:06.53]at the speed of light,
[01:08.14]they would appear much heavier
[01:09.87]and larger and would seem to move very slowly.
[01:12.34]
- Human acts have repercussions far beyond the frontiers of the human world. 人类行为所产生的影响远远超出人类世界的范围。
- They are highly interested in the frontiers of science. 他们对于科学的新领域有浓厚的兴趣。
- The solution can be expressed by a mathematical equation.答案可用一个数学方程式来表示。
- This equation is known as the ideal gas law.这个等式被叫做理想气体定律。
- Finally they accepted Einstein's relativity.他们终于接受了爱因斯坦的相对论。
- There is no relativity between the two matters.这两件事毫无关系。
