A mathematician's job involves looking at patterns, making hypotheses, and providing explanations to many phenomena that occur in real-life. In this talk, the speaker will explore this way of thinking using origami examples. Participants will look at (i) how to equally divide a piece of paper into 1/3, 1/5, 1/7 or 1/9, (ii) how many sides a paper flap can have after folding once, (iii) how to determine if a crease pattern produces a flat origami.

Have you ever thought about how food security is being affected by worldwide issues such as the COVID-19 pandemic and how conventional agriculture can have negative impacts on the environment? In this workshop, these important topics will be discussed and participants will explore ways in which modern agriculture such as hydroponic and aquaponic systems can contribute to sustainable development.

In this workshop, participants will develop a chatbot that recommends a restaurant to the customers. Through the development, participants will gain a glimpse of knowledge on Machine Learning and particularly how it is being applied in Natural Language Processing (NLP), a current hot topic in artificial intelligence (AI).

On a to-do list of a day, there are several tasks to be completed. In order to finish the tasks, mathematics can be involved in, for example,
1. how to minimize the completion time by optimizing the order of these tasks,
2. how to schedule the route in order to minimize the travel distance,
3. how to make sure the safety for online activities... etc.

In this talk, the speaker will talk about many daily-life examples with mathematics behind it and how we use mathematics in various scenarios!

Science, such as chemistry, is always needed to provide accurate and objective information, assisting the investigators to solve a crime case. In this workshop, participants will learn about the basic knowledge and skills of forensic toxicology and illicit drug analysis. Hands-on experience will be provided to tentatively identify an illicit drug via narcotic drug smell (mimics) and thin layer chromatography.

Sustainability Gallery (S Gallery) is one of the key public education projects of “Institute of Bioresource and Agriculture” (IBA). Supplemented with an interesting spaceship astronaut training story, S Gallery is furnished with advanced multimedia technologies (e.g. 4D, AR) to showcase exhibitions of biological resources, organic agriculture and sustainable living, which allows visitors to gain knowledge via an interactive approach. After the visit, visitors are encouraged to reflect on the problems of contemporary lifestyle and to live sustainably.

Intelligent robots are electronic gadgets that can move in special fashions in response to changes in the environment. They are gaining increasing popularity worldwide. It is believed robots can replace human beings to perform routine or dangerous tasks. In the "heart" of the robot lies an electronic control circuit. The control dictates how the robot should respond when the environment changes. In this workshop, participants will construct a robotic insect using simple light sensors and motors. The overall features of the insect are as follows. In the absence of any obstacle, the insect simply moves forward in a straight line. When an obstacle is present, the insect will turn when it is sufficiently close to the obstacle. Once the insect makes a turn, it continues to move in a straight line until it approaches the next obstacle.

Healthy Lifestyle is one of the learning goals of school curriculum [Reference: Secondary Education Curriculum Guide, Booklet 2: Learning Goals, School Curriculum Framework and Planning, the EDB of the HKSAR (2017)]. The EDB has provided plenty of supports, e.g. school activities and healthy school policy, to help students to develop a state of physical, mental and social well-being and establish healthy lifestyles. Quantitative analysis and assessments of healthy lifestyle (e.g. physical fitness and emotions) can be implemented by smart IoT sensors. This talk aims at explaining the working principles of various smart IoT (Internet of Things) components and sensors for the applications of healthy lifestyle assessments. Examples of topics include:
• Sensor Technology Components;
• Acceleration sensors;
• Photoplethysmography (PPG);
• Heart Rate Variability (HRV);
• Stress index;
• Breathing Sensors; and
• Sensing for Sleep Stage Classifications.

Cosmetics consist of a large groups of organic chemicals that we commonly encounter in our daily life. Different chemical components with various functions are mixed together to turn into the readily used cosmetics and skin care products that provide protection and enhancement of one’s appearance. In this workshop, participants will learn more about the chemistry in cosmetics, and be able to DIY their own lipstick and skin care essence.

Similar to how humans see the world through our eyes, mobile phone can also "see" the world through its camera. It understands the environment, such as depth and lighting information, by detecting feature points in the captured images. With the help of existing APIs, we can build mobile app that can understand the world and interact with information, which is so called Augmented Reality (AR). For example, we can place a virtual kitten in the real world and watch it moving around. In this workshop, participants will develop a mobile app that can provide AR experiences.
