Baptist Lui Ming Choi Secondary School's "Sustainable Pearl Education": A Scientific Exploration from Shing Mun Reservoir to the Campus Micro-Ecosystem
In recent years, sustainable development (ESG) and environmental conservation have become core global concerns. Under the Pearl Professor initiative, we are committed to combining traditional pearl farming with modern science education. Recently, Baptist Lui Ming Choi Secondary School completed a "Sustainable Pearl Education" project focused on scientific inquiry. This was not only an attempt to bring nature into the school, but also a wonderful journey that stimulated studen

Understanding Geography Through Pearl Farming
From AI to Geography In September 2025, I was invited as a guest speaker at an AI tool launch event, sharing insights on pearl farming, marine restoration, and sustainable development. I already knew that the principal of United Christian College would be attending the event. Of course, as part of business development, getting to know the principal is a standard practice. However, I have another purpose. I wanted to introduce myself to the principal in advance as a future vol

When Pearls Meet Seasonal Changes: Mathematical Thinking on a Variable Growth Model
Math in Biology: Quantity in Summer, Quality in Winter There is a golden rule in pearl farming: in summer, the water temperature is high and metabolism is fast, so pearls grow quickly but have a loose luster; in winter, the water temperature is low and growth is slow but the layers are dense. This "variable growth" makes the calculation of the number of pearl layers very interesting. 🟢 Middle School Math Practice: Partial Mean Let's assume we simplify a year into two seasons

The Mathematical Beauty of Pearl Farming: Arithmetic Growth Through Daily Accumulation of 4.77 Layers
The formation of a pearl is not an instantaneous process. When the nucleus implants inside a mollusk, the mollusk secretes layers of nacre to coat it. Research suggests that a high-quality pearl can form approximately 2,615 layers within 18 months ( reference ), which translates to an average of about 4.77 layers secreted per day. These small numbers serve as excellent teaching materials for middle and high school math models. Pearl Layer 🟢 Junior High School Math Practice:

A biology lesson combined with a math lesson! How many times do you need to change the water when raising pearl oysters?
Hi everyone, I'm Pearl Professor. Recently, I asked Mr. Hui (@Mathemagic) a problem about applied mathematics. I asked him a very interesting question—"Contrast with water!" This isn't just a math puzzle; it's also a real step in pearl oyster farming. Today, I'd like to revisit this topic, firstly to share it with more friends, and secondly to invite Dick Sir or his team ( @dickhui_dhmp ) to add to the discussion, interact, or even solve it again using his "Mathemagic" meth
