[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 equation² "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 relativity³"
[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]
