GCNU1025 Numbers Save the Day (3 units)
- Medium of Instruction:
- English
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. This course 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.
