Organised by Hong Kong Light Pollution Research Project Team, The University of Hong Kong, in association with Hong Kong Science Museum and Hong Kong Space Museum

Light pollution is a global environmental issue in which excessive artificial outdoor lightings affect the natural environment and the ecosystem. Among different forms of light pollution, light trespass needs immediate attention due to its potential adverse impacts on human health. The problem of light trespass is particularly evident in a densely-populated metropolis like Hong Kong. Using Artificial Intelligence (AI), computation methods are developed to detect, classify and quantify the light sources in images and videos taken at the street level. Results can be used as a light condition analysis for analysing whether light emitters are sourced from commercial buildings or street areas to determine the effects of light pollution on residents’ views. As a citizen science project, members of the public are encouraged to contribute images or videos via a mobile app to expend the coverage of the study. The lecture introduces light pollution, citizen science projects and the research conducted by the University of Hong Kong.

"Interstellar"

Date and time: 20.4.2025 (Sunday) 2:00 pm - 6:00 pm

In the not-too-distant future, Earth will be in a serious environmental crisis, which will put everyone’s life in jeopardy. Cooper joins a mission to save mankind. He travels through a wormhole near Saturn to an unknown galaxy, in which he looks for a habitable planet. During the interstellar journey, Cooper experiences the effect of time dilation, gets sucked into a black hole and enters a five-dimensional space inadvertently. He gradually realises that this space has been created by future humans to save the past. Using gravity, he communicates with his daughter Murph on Earth. He transmits crucial data to her, which help her solve "the gravity equation", and thus realise the plan to save mankind.

With Kip Thorne, the Nobel Laureate in Physics 2017, serving as the scientific adviser and executive producer, Interstellar presents accurately scientific theories such as relativity, black holes and wormholes on the silver screen, allowing the audience to experience the charm of science through a gripping narrative.

Post-screening talk

The speaker will introduce the astrophysics behind the film, such as black holes, wormholes and time dilation.

Speaker: Prof. Chan Man Ho (Astrophysicist and Associate Professor, Department of Science and Environmental Studies, The Education University of Hong Kong)

"A.I. Artificial Intelligence"

Date and time: 21.4.2025 (Monday) 2:00 pm - 5:45 pm

In the future world, humans create robots as substitutes to meet various needs. David is the first robotic boy endowed with real human emotions, and his love for his "mother" Monica is unwavering. Monica has a son who is afflicted with an incurable disease, and thus cryogenically frozen. To fill the void in her heart, she adopts David as a substitute. One day, Monica’s biological son gets recovered miraculously and returns home, which turns David’s life upside down. David desperately looks for a way to become a real human, hoping to regain his "mother’s" love.

Directed by Steven Spielberg, the sci-fi film explores profoundly the relationship among love, humanity and technology, making it a classic in the genre of sci-fi films with robots.

Post-screening talk

The speaker will share his views and perspectives on the film in the context of science fiction movie and comment on various issues featured in the story: artificial intelligence, machine emotion, ethics and morality.

Speaker: Prof. Yam Yeung (Research Professor, Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong and Principal Investigator, CUHK Jockey Club AI for the Future Project)
