My dad just gave me a speech about his opinions on human's modern developments:
- Europeans had developed physical sciences, social sciences and humanities together, so they created modern lifestyles. Americans benefited from it and created more comfortable lifestyles based on technological progress;
- Asians, for example, Chinese had only focused on the developments of humanities and some of social sciences in the last couple of thousands years, so it was impossible Industrial Revolution could have incurred there. It's very difficult for Asians to catch up but they are making tremendous efforts to improve now;
- Africans have a lot of opportunities to start fresh.
He was a renown civil engineer, so had a lot of knowledge in physical sciences. However, he had spent a lot of time in social sciences and humanities as hobbies after retiring in the last 20 years. Recently, he found that he had to go back to physical sciences to learn new theories and applications to resolve many problems and issues in social sciences he was interested in. I noticed he had been reading a new version of Physics textbook in Chinese recently and periodically heard his comments on so many new developments in the book he didn't know when he was young.
This is why I would like to apply more mathematics into economics. No, it is not new because many economists are mathematicians. However, there are lots of room for developing economics into a more rigorous science.
I just started reviewing the knowledge I learned when I was young, such as differentiations, Integrals, differential equations, linear algebra and mathematical statistics. There is still a long way to go for me to building my own models. At least, I already started, so I feel great.
