Hi everyone. My topic today is Maths in my Eyes.
When I mention the word maths” some adjectives will come to mind, boring, difficult and complicated. But I think maths is very interesting. It is used almost everywhere in our life and also related to art and music.
We all know one geometrical concept, the golden section. It's very important in painting, sculpture and architecture, such as the Parthenon in Athens and the Venus de Milo. In nature a little pentagonal flower has its golden section. It looks beautiful.
What about its connection with music? Lets take a look at a straight and tight string. Pluck it, and then halve its length, then pluck it again. The sound we hear is the same note but a higher frequency. The Greek mathematician Pythagoras discovered this law and it developed into the musical scale we know today.
Another example is from the famous composer, Bach. When we listen to his music in Well-Tempered Clavier”, we find the notes are always getting higher .But amazingly, in the end, it comes back to the initial height. Why is it? That's why Bach was great! It's a very interesting maths problem. We call it a paradox.
These days we learn maths at school. The only purpose is to get a high mark. But I personally think that those with curious and creative minds will open the door to the world of maths. Just as Galileo said, Mathematics is the alphabet with which God has written the universe”. Maths, in my eyes, is a fascinating subject that needs our passion and imagination. In the end I hope you love this boundless treasure and enjoy the magical world of maths!
Thank you.
