What is the course about?

Numbers play numerous roles in our everyday lives. They are used to describe the natural world, to communicate information, and to model important daily applications. GFQR1016 begins with a simple math topic: “integers 1, 2, 3…” and guides students through its important (unknown to most) properties and everyday applications. After a reminder about the basic properties of numbers, besides the obvious example of telephone numbers, students will begin to see the how “features” can be hidden within, say, our HKID number. From “fun to know” to “extremely important” applications, topics will range from such things as the composition of digital pictures and photo-touching software to security that helps us assess the risk of everyday online transactions (which is based completely on “numbers”). With a newfound awareness of “numbers” around them, students can make sense of many more things in their daily lives. We hope that this course will help students see the many diverse applications of mathematics and what makes it all possible.

What do the students say about this course?

課程中提及很多日常中見到的數字,例如身份證號碼、信用卡號碼等等。這些數字背後原來係有一套方法編出來,而不是胡亂隨機的,真的好厲害。除此之外,看過《解碼遊戲》這電影的人都可能覺得戲中男主角好厲害,可以將別人已加密的訊息解密。課程中我們會學習加密和解密的方法,如那電影一樣,很好玩。
