Why is the sun yellow? Or why do we need science and technology?

Well, have you ever wondered why the sun rises in the east and sets in the west?

Why the sun is yellow? Why the sky is blue? Why Australians are not upside down? Why toast always falls on the buttered side? How aeroplanes stay up in the air? Why some people have blue eyes and others green or brown?

All of these questions can be answered by science and technology. It is all about finding out why and how things work. If you look at the world around us today, there is nothing that is not touched by science and technology from the food you eat to the clothes we put on, to the book we read, the phone we use and the car we drive.

It is amazing if you really think about it, how much of our lives are affected. It is also amazing to think that a lot of what we do is through experimentation. We experiment with the food that we like, with the music we want to hear – that’s taste and hearing using 2 of our sense right there, plus design, engineering, biology too.

If you really think about it, each of us is a scientist in our own small way and we never stop learning. So keep on asking questions and learning the answers because through asking, learning and experimenting, we never stop growing.

I am always reminded of this by the inspiring words of the late Stephen Hawking: “Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. Be curious. And however difficult life may seem, there is always something you can do and succeed at. It matters that you don’t just give up.”

Yours in science
