The First Page

Well, as you can see, this is the first page of our blog. Mostly, this blog is about Mathematics, Computer Science, Software Engineering, Economics and probably something about law.

What I want to say in the first page here is that economic is a science as well as physic, chemistry or biology. We use data, we build a model or find a possible expression for a¬†phenomenon,and we bring our theory into our life. The only difference is that we study on human’s economic activities instead of natural phenomenon.

An example:

In 1960s an economist found a mathematical relationship between unemployment rate and inflation rate, which provides a possibility to lower the unemployment by using a high inflation rate. The Phillips curve:

Look how close it is! What a great model!

Wait a minute… Where is the data of 70s 80s or 90s?

Anyway, just remember Economics is a serious science.
