You are a tree.

When you see a tree in a forest, you can't see the whole part of the forest by your own eyes without tool like camera.  It is obvious that you are in the forest, and to see the forest needs a higher position outside of the forest to look down.

You are a tree in your forest called society.  Of course I also a tree in my society.  Furthermore everyone is a part of the society.  But at the same time, you are a forest of your body.  Here is the essence of life.

Let me quote my favorite story "Alchemist" written by Paulo Coelho.  His blog http://paulocoelhoblog.com/ is actually, definitely and no-need-to-explainly more sophisticated and powerful.  But going my own way is much more important than just getting his points.  I also hope you reading this blog are on your way and cooperation between us beyond the physical distance will drive our own ways forward respectively.  Now back to the Coelho's quote;

"Well, there is only one piece of advice I can give you," said the wisest of wise men. "The secret of happiness is to see all the marvels of the world, and never to forget the drops of oil on the spoon."

The spoon of  oil drops is handed by you.  This situation may be only in having the oil drops like taking medicine or soup.  But if you do something with behavior of handling the spoon with oil drops, the action can be totally different from doing something only, because you need much more care for the spoon additionally. 

Concentrating on the spoon requires rest of all things.  It looks like that when you see a tree, you lost the vision of the forest.

Math is a world of numbers.  For example, when you see number of 2, you may lose the number world.  Considering the Riemann Hypothesis about prime numbers, we have not seen the whole image of the world, despite we have already achieved to see the whole sphere of the earth from space.  But math has its own history over 2000 years and on the course, it can be said that physics was born from Math.

To cooperate is difficult or sometime impossible.  To fly like a plain was impossible only before 100 years ago.  Understanding how thing works is powerful.  Math can be a tool for getting an index of what is going on. 

Here is my new math program of differentiation to find the point of extreme.  http://tobea.sakura.ne.jp/mathcontext/dif.html

Math app for calculation, geometry and linear function is now on Google Play.

Thank you for reading.  Now I totally forget the spoon of drops.  Changing myself can lead to a different place whether it is good or bad.  Needless to say, I am challenging to find my best, and you too.
