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.


Pure Sciences

1. Physical Science
-Physics
-Chemistry
-Astronomy

2. Life Science
-Botany
-Zoology
-Genetics

3. Earth Science
-Geology
-Seismology
-Oceanography

Applied Sciences

1. Mathematical Science
-Algebra
-Geometry
-Calculus

2. Social Sciences
-Anthropology
-Political Science
-Economics

3. Engineering
-Chemical Engineering
-Mechanical Engineering
-Electrical Engineering



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

Let's Celebrate Pi Day!

I saw in Google’s page this cute logo in commemoration of Pi Day.

I didn’t know there was such but now that I did, I checked some details.

Pi Day is celebrated on March 14 or 3.14 being the first three digit of the pi value (3.141592653589793238462643383279502884197…infinite series).

It also coincides with the birthday of Albert Einstein, a famous scientist and mathematician.

Pi is the ratio of the circumference of a circle to its diameter. The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter.

 

where c is circumference and d is diameter.

So when you order a 16 inches pizza it refers to the diameter. You might want to measure it's circumference by a tape measure but why bother? you can use the equation above and the answer is 50.24 inches (C = 3.14 x 16). Easy right?

Happy Pi Day everyone!
