Science: Tree of Knowledge

Tweet

When we say branches, the first thing in our mind is a tree. From one trunk sprouts branches, twigs then leaves.

So when we say Science it is one big tree of knowledge with the different fields as its branches.

Here I listed the major branches or divisions of Science as Pure and Applied Sciences, further comes other smaller branches or twigs like Physical Science, Life Science, etc. Down comes the leaves with Physics, Chemistry, Botany and the like.

1. Physical Science

-Chemistry
-Astronomy

2. Life Science
-Botany

-Genetics

3. Earth Science

Applied Sciences

I'll discuss those different Sciences (or maybe discussed some already) along the way.
