Math Is Fun

I launched this Mag to demonstrate to my then-5-year-old son that math can be a fun and fascinating subject, rather than boring and mundane. As a child, I became drawn to math and science through reading intriguing stories, and I felt that there was a lack of similar materials available for young kids. So I decided to create a Mag to showcase the wonder of math to my son. The primary goal is not to provide children with specific math knowledge, but to immerse them in the enjoyment of math. If we can connect math with the word "fun" in our kids' minds, then we will have accomplished our objective. After all, interest is the most effective teacher.

I recalled this famous interview question first popularized by Microsoft in the early days and then adopted by other companies: Why are manhole covers round? So I asked my son. “Because it looks nice?” “It’s more than that. There is […]

“How many sides does a paper have?” I asked my son, who was watching TV. “2” “What if I tell you I can make a paper have ONLY one side?” “No Way!” “Come and I will show you how to make a Mobius Band.” Well we are in the year 2021, so there is a […]

One day, he raced with the King of Qi. They each had three horses, ranked as “fastest”, “faster” and ”fast”. They held three matches. Whoever […]

“Can you explain how computers work?” Son was using an ipad and asked me all of a sudden. “That’s going to be a long lesson. How about I start with the basics: the binary numbers. Everything on your computers are represented in binary numbers.” “Oh, really? What are binary numbers?” I moved to a floor […]

Continuing the topic of binary numbers, I asked my son, “Do you know Morse code?” “Ah, I do! It’s used in telegraph.” “Right, telegraph is no longer used in regular communications these days, but the story about Morse code is still interesting. I explained, “Electrical telegraph was invented in the nineteenth century and was the […]
