The spirit of the Maker Movement was born from passion and providing better solutions that'll help others. What started out as a simple movement has made its way into many different areas of the world, including education. Making helps bring people of all different backgrounds and skill sets together, allowing them to invent with their heads, hearts, and hands each involved. These authentic connections also help prompt creative solutions that make a difference and showcase each person’s unique talents. Now a phenomenon with a global impact, the Maker Movement has brought so many creative people together. Now, that spirit has found its way into countless schools, classrooms, and libraries, helping today's teachers capitalize on the Maker Movement in education and offer fresh ways to excite all students. And, it's great to see how educators empower them to learn and express themselves through perseverance and project design.

Maker education and the maker movement is all about project-based or problem-based learning. It relies on hands-on, collaborative experiences where projects focus on solving real problems in order to demonstrate learning.
Maker education originated from the maker movement in 2005 and gained traction in large part due to Make magazine and the popularity of events like Maker Faires. This movement brought together DIY-ers, hobbyists, and tinkerers from all different backgrounds who wanted to improve the world around them through collaboration and experimentation.
This emphasis on discovery through creating is at the heart of maker education—and the maker education movement.

By the end of the decade, the Metaverse could be worth between $6 trillion and $13 trillion. But what is it?
The Metaverse is not simply immersive virtual reality or a really cool video game. It's a combination of technologies that allows an unlimited number of users to experience real-time rendered, 3D virtual worlds synchronously and persistently.
It is difficult to predict how the Metaverse will evolve, just as it was nearly impossible to predict the emergence of Facebook during the era of Windows 95. The Metaverse will not replace the internet, but will build upon and extend it.

‘The metaverse’ does not yet exist. It merely exists as many different visions of a future of computing, especially a future that Meta and Mark Zuckerberg would like to shape. Meanwhile, the history of computing has been marked by visions of augmented or virtual reality. At the same time, many media-technical elements of the metaverse-to-come already exist, such as games engines or VR glasses. This course therefore deals with visions of metaverses and their current media-technical instantiations. It explores some of the back stories of current and future metaverses, takes a critical look at current media, technical, social and economic aspects of existing offerings, and offers practical experiences of virtual worlds and the tools used to build them.

The lecture will explore the role of technology in promoting environmental sustainability. It focuses on the development and implementation of innovative technologies that can help address environmental challenges and contribute to a more sustainable future.We are developing green technologies to benefit sustainable environment, which will enable people and the environment to prosper together. The Center for Filtration Research (CFR) at the University of Minnesota, collaborating with 20 leading international filtration manufacturers and end users, was established to develop green technologies to mitigate PM2.5, VOCs, ozone and other environmental pollutants. CFR investigators perform fundamental and applied research on air, gas and liquid filtration. The current research projects include indoor air cleaning and Covid prevention, bioaerosols sensor development and evaluation, nanofiber production and modeling, nanotechnology and instrumentation developments, among others. Large-scale air cleaning towers are established in Xi’an and Yancheng in China, and two additional towers in Delhi, India. They are developed to mitigate PM2.5 pollutants in urban air. The second-generation tower in Yancheng is developed to reduce not only the PM2.5 but also CO2 in the atmosphere. The construction of a set of large-scale air cleaning towers to capture 16 million tons of CO2 annually is proposed. All these research and development activities are helping to improve sustainable environment.

The Virtual Reality (VR) Training for Laser Cutter Operation was developed as a supplementary training tool for the PolyU Library’s technical support staff to practice and become familiar with the operation of a laser cutter. The application simulates the environment, laser cutter model, essential operational procedures, and corresponding responses of our laser cutter in service as realistically as feasible. A computer with a simplified laser cutting software interface was also built to simulate the software operation. Interactions (primarily on/off) with all other peripheral equipment, such as the ventilation system, air compressor, and earmuffs, are triggered through button clicks in an on-screen menu. The application simulates the operational procedures and corresponding reactions of the real laser cutter as closely as necessary. New technical staff members who are trained but not yet proficient with laser cutting can practice safely in an immersive environment enabled by VR technology.

A rapidly expanding research area involves the development of routes to shape programmable three-dimensional (3D) structures with feature sizes in the mesoscopic range (that is, between tens of nanometres and hundreds of micrometres). A goal is to establish methods to control the properties of materials systems and the function of devices, through not only static architectures, but also morphable structures and shape-shifting processes. Soft matter equipped with responsive components can switch between designed shapes, but cannot support the types of dynamic morphing capabilities needed to reproduce continuous shape-shifting processes of interest for many applications. Challenges lie in the establishment of 3D assembly/fabrication techniques compatible with wide classes of materials and 3D geometries, and schemes to program target shapes after fabrication.
In this talk, Prof. HUANG Yonggang will introduce a mechanics-guided assembly approach that exploits controlled buckling for constructing complex 3D micro/nanostructures from patterned two-dimensional (2D) micro/nanoscale precursors that can be easily formed using established semiconductor technologies. This approach applies to a very broad set of materials (e.g., semiconductors, polymers, metals, and ceramics) and even their heterogeneous integration, over a wide range of length scales (e.g., from 100 nm to 10 cm). To allow realisation of 3D mesostructures that are capable of qualitative shape reconfiguration, Prof. HUANG devises a loading-path controlled strategy that relies on elastomer platforms deformed in different time sequences to elastically alter the 3D geometries of supported mesostructures via nonlinear buckling. Prof. HUANG will also introduce a recent work on shape programmable soft surface, constructed from a matrix of filamentary metal traces, driven by programmable, distributed electromagnetic forces that follow from the passage of electrical currents in the presence of a static magnetic field. Under the guidance of a mechanics model-based strategy to solve the inverse problem, the surface can morph into a wide range of 3D target shapes and shape-shifting processes. The compatibility of these approaches with the state-of-the-art fabrication/processing techniques, along with the versatile capabilities, allow transformation of diverse existing 2D microsystems into complex configurations, providing unusual design options in the development of novel functional devices.
