It was difficult for most students to study science about chemistry, and electron. Thus, most Korea students did not want to study science and major in science. However, many students started to study subjects regarding science the other months because Korean government decided to support scientists like getting a job more easily. After that, Korea could earn lots of money thanks to superb scientific technologies such as exporting the nuclear power technology abroad. In other way, we have to take a lot of time and efforts to learn the science, but we can get wonderful benefits from the investment.
