Zero

If someone were to ask me, ' what is my favorite number', I would have replied 'zero'. Although it seems insignificant at first, I think zero is the most phenomenal number.

In the first place, zero represents the nothingness, which in fact does not exist in the real world at all. Actually, the mind of human can only understand the existence of something, but not the non-existence of something.

According to the Pythagorean Philosophy, there are four fundamental concepts of Mathematics: harmony, astronomy, geometry and arithmetic.

Arithmetic is primarily concerned with addition and subtraction, or more precisely counting. The entities of the same category can be added together endlessly, until the group becomes infinitely large. This is the basic concept of addition. Similarly, subtraction is the reverse process. From a group of entities, each entity is taken away until there is nothing left. In fact, the subtraction introduces a problem - the empty group.

Geometry is primarily concerned with size, location and shape. It was Thales who first introduced a point to the Geometry, which has no size nor shape but just location.

Harmony is primarily concerned with relative comparison: how large an entity is compared to the others. In fact, most arts and musics are based on harmony, which defines the ratios between different and similar entities. For example, musical notes are defined in relative ratios and the geometry of drawings are defined in certain ratios. The most famous ratios are the golden ratio and PI.

Astronomy is primarily concerned with relative location and motion. The first astronomers were the merchants who used the location and motion of stars to calculate their location in the sea or in the desert.

Although the basic concepts of mathematics are defined in 4 aspects: harmony, astronomy, geometry and arithmetic, the idea of nothingness or emptiness was not well defined in Greek Mathematics. There were school of philosophers who agreed with nothingness while others strongly argued. For example, those who opposed the idea of nothingness argued that a stick could be divided into 2 pieces, 4 pieces and so on until it became infinitely small.

The idea of nothingness or emptiness (Śūnyatā) comes from Indian Philosophy. Some ideas of emptiness can be seen in Taoism as well. Through the Arabic Philosophers, the ideas of emptiness was imported to the Western World, until it became successfully integrated with the existing Greek Mathematical Philosophy.

It is in fact the idea of Zero which laid the foundation of Modern Mathematics and Physics. Calculus had not been invented until after the idea of zero was well defined in Mathematics, although the basic concepts of Limit and Continuity, such as Zeno's Paradoxes were already introduced. Therefore, zero is the most phenomenal number at least I believe.



Heroes of Bagan

Today, I received a book called Heroes of Bagan  by Thaw Dar Swe (Originally written by Daw Khin Myo Chit as Anawrahta of Burma) from Grandma. I am really happy to read it again :). I first read this book when I was 14 year old or so. It was Grandpa who bought me this book. Maybe it is one of the reason why I am fascinated about the Bagan (Pagan) Dynasty.

As the original author, Daw Khin Myo Chit, said, the book may not be historically correct; however, we can see the bond between the king and his dependable subjects and how they took part in the country building tasks. We can see loyalty, betrayal, love, hatred, sacrifices, war, peace, conquerors, losers, sufferings, passions, and above all else, the unity of strength in this book.

The story is, actually, more than 1000 year old. However, the characters of the story are so vivid that they seem still alive until today. Actually, there are many stories about the origins of nations or countries, for example, the Romance of Three Kingdoms in Chinese History,  Ivanhoe and King Richard in English History, and Iliads and Odyssey in Greek History. We are not sure how accurate are these stories, but more importantly they are still alive until today.

Education = Exploration + Experiment + Experience

"The scientist does not study nature because it is useful; he studies it because he delights in it; and he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, and if nature were not worth knowing, life would not be worth living"
-Henri Poincare

This is the quote from the preface of my physics book. This quote not only reflects the passion of a great scientist, but it also points out the meaning of education.

Education, as I believe, is the integration of exploration, experiment and experience.

The first purpose of education is to open our mind, and to see the world more openly and widely. To put it shortly, the first purpose of education is to explore. Every branch of knowledge known to the humanity is not complete yet. There are more to explore, more to see and more to discover. That is why it is very important to encourage  to explore more without limiting the potential. Since we were born, we in fact have a huge curiosity to learn and explore. We felt delight to see new things; we felt happy to see the vast sky; we felt enjoyable to see the butterflies flying. In fact, when we truly ask ourselves about the world around us, how many levels of 'why' we can actually ask. For example, if we ask ourselves why the Earth is rotating around the Sun, the answer is the pull of Gravity. But if we continue to ask why the gravity pulls, then we have reached the dead-end because we still don't know why the gravity pulls. Therefore, every exploration starts with a question. The more we ask, the more we can explore.

The second purpose of education is to experiment, and to try. In fact, trying is always associated with both failures and successes. However, the education is to encourage experiments even though there are risks of failures. In fact, the second purpose of education is to teach that failures are as important as successes in experiments. According to the Quantum Mechanics, we have a one millionth chance to be able push through a brick wall, which means if we keep trying until one million and one times, we can successfully pass through the wall. By the way, it is a joke though :) 

And the final purpose of education is to experience, and to learn from both exploration and experiment. There is a world of difference between knowing the England and actually having been to the England. Therefore, the more experience we have, the more we are closer to the meaning of education. In fact, the experienced society is the educated society. After all, the leading societies are the societies which have enough experience to build rockets and robots, to explore outer space, to venture into deep water and so on. But these experiences did not come without a price; all experiences come from exploration and experimentation.

I think the educated society cannot be measured by the number of university graduates it produces, but by the number of explorers, inventors, entrepreneurs, scientists, artists, writers, politicians and so forth.

And the last, but not the least. Education is a life-long learning; it is almost impossible to teach everything in school. However, it is possible to teach the spirit of life-long learning: to explore, to experiment and to experience.
