4A Pang Wing Hei

Good morning, I am Pang Wing Hei of class 4A. Today, I would like to share a book called The secret of the Universe.

Do strange thoughts flash through your head: why is it so easy for us to stand firm on the ground? Why can we move left, right, back or front? What help us do the morning exercises with ease? Don’t you think that it’s time for us to know more about our universe?

The book would provide you the possible solutions to your problems. It’s immediately clear why this book attracted a standing ovation when first published in 2010: it is a stunning piece about astronomy.

First and foremost, do you know how many planets are there in our Solar system? You’re right. The answer is 8. Can you name all of them? They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. So, how are these planets formed? Here is a theory called ‘The Big Bang’. According to the Big Bang theory, the universe expanded from an extremely dense and hot state after the Big Bang. During the expansion, the temperature becomes lower and new substances were formed. Many years later, the Milky Way Galaxy was formed, Solar system was formed and our earth was formed as well. There were also some other theories in this book which are about the start of the world. However, most of the scientists believe in the Big Bang theory.
Let me share one more funny fact with you – the dimensions of spaces. O-dimension space refers to a space with a point where there aren’t any lengths. How about 1-dimension space? It refers to a space with a line where we can only move left or right. How about 2-dimension space then? Bingo! It’s a space with a surface where we cannot just move left or right, but back or front as well. Here comes to a question. What about our space? Is it a 3 or 4 dimension one? Make a guess. Yeah it’s a 4 dimension space which includes a surface, height and one more thing. Do you know what it is? It is TIME.

So do you know why we learn science now? Science is the STUDY of the world around us – by learning science you learn HOW to study and learn. Science is the study of the WORLD around us – you learn all about the world that we live in – how things work, what living things there are, how things happen, etc. And most importantly, ANYTHING you learn makes you smarter!
Without science we wouldn’t have all the great inventions that we have to today that scientists have created. Science is also important because without science our world would be a lot sadder
A sense of the mystery of the cosmos is probably as human as can be and has been with us since cavemen put paints to walls to represent reality.

Can science solve this mystery, and will the feeling it inspires go away once it’s solved? Let’s explore the joy of reading and learn more about science! That’s all I want to share with you today, thank you.
