Maths in my Eyes

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.

我眼中的数学

大家好!我今天演讲的题目是：我眼中的数学。

一提到“数学”这个词，你们一定会联想到“枯燥”、“复杂”之类的"形容词。不过在我眼里，数学是一门妙趣横生的学科。它十分广泛地被应用在我们生活的每一个角落，还与音乐、美术有着极大的联系。

我们都知道一个几何概念：黄金分割。它在绘画、雕塑、建筑艺术等方面都占有重要地位。比如雅典卫城，断臂维纳斯就运用了黄金分割。在大自然中，一朵五边形的小花也有它的黄金分割点，于是它看上去就很可爱了。

数学和音乐又有什么联系呢?让我们来看看着根紧绷的线。拨动一下，然后抓住绳子的二分之一处，再拨一下，就会听到在不同高度的同一个音。毕达哥拉斯发现了这一点。于是它逐渐发展成今天的音阶。

另一个例子是关于大作曲家巴赫的，如果我们仔细聆听他《平均律钢琴曲集》中的旋律，就会发现音高总是在慢慢上升。但出乎意料的是，在乐曲的结尾，它却回到了原来的高度。这是为什么呢?这大概就是巴赫的伟大之处了。其实，它是一个非常有趣的数学问题，我们把它叫做“数学悖论”.

如今我们在学校里学习数学，只是为了应付考试。但我个人认为，打开数学之门的，是那些有好奇心和创新精神的人们。就像伽利略所说的：数学是上帝用来记载宇宙的字母表。数学在我眼中是一门美妙的学科，它需要我们的激情与想像力。最后，我希望大家也能喜欢这宝藏，爱这神奇的数学王国。
