Day 1: 
1. Importance of Water - Dirty and Clean (Professor Ng Wun Jern)
I have learnt a few things from this plenary session. Firstly, I knew more about the specific diseases such as Cholera, Typhoid Fever, and Dysentery and not all microbes are bad. Secondly, I have learnt why should pollution bother how bad it is and us. Some examples of how pollution affects us are smell, chronic health risk, social and economical impacts. Also, 1.1 billion people have no access to water and 2.4 billion people have inadequate water sanitation. Lastly, I understood that there are still solutions to solve the problems and that an expanding industries meets urgent needs where innovation and entrepreneurship opportunities for students. And some of the technologies used are membranes for reclamation and water distillation. It will be an opportunities to make a difference for others and not only for yourself.
2. Revolution of Microelectronics Technology (Professor Yeo Kiat Seng)
Microelectronics Technology are the transformation of higher value added products. This is due to supply change and increase of customer needs. This plenary session have talked about Integrated Circuits and how Electronics are used. Integrated Circuits are invented in year 1958 and Electronics in pervasive - the 'brain' of electronics gadgets. Electronics enables entertainment, medicine, communication and transport. Also, I have learnt an acronym regarding Integrated Circuits. There are Nine 'O's in Integrated Circuits - Bio, Radio, Auto, Info, Nano, Water=Hydro=H20, Audio, Video, Energy=m.c^2=m.c^two. The use of Bio-nano Electronics are programmable blood, electronic contact lens, brain implant, epiretinal implant-which enables the blind to see. A question was asked, Will brain implant cause cancer? The reply by the professor was no, reason being that the frequency of the brain implant can be turned down which will reduce the radioactive waves.
3. Innovative breakthroughs in Nano-Science and Nano-Technology (Professor Ma Jan)
This plenary session is about Bio-Technology, Nano-Technology and Defense Technology. I have learnt a few things in this session. Firstly, I learnt about the concept of smaller size for a fixed volume = larger surface area. Secondly, I have found out that in the future, there will be Quantum Dots (QD), which will shrink huge amount of information into a small object. The example given was that it is able to shrink information of house of library of congress in a sugar cube. Lastly, I have learnt that nano-technology can form a very strong material. Such material is usually called Biomineralized Fluoridate. An example of how this material works will be through the use of making a soldier's armor. This allows the soldier to have better protection that then enables them to stay longer in the battlefield. Another example of how using nano-technology can be used to build nano-object such as flies to spot its enemy way up in the sky or very near them. This will help the soldier to locate their enemy easier and faster.
4. IT for Animation (Professor Seah Hock Soon)
Computer animation is used predominantly used in video games, and movies are also increasingly reliant on animation and computer graphics special effects. This plenary session have taught me a few things. Firstly, animation usually used 24 frames per second and one kind of animation will be stop motion that is storytelling. It will be drawing many frames and filming it all at one go. However, such kind of animation requires manual labor and it will cost alot of money to hire people to draw the frames for the animation, as it is tedious and tough. Secondly, I have also found out that it will be much cheaper to use 3D animation instead of 2D as 3D do not depend much on manual labor but through the use of IT instead. Lastly, mathematics are involved such as Linear Algebra, Geometry and Calculus. In this plenary session, I can see that we can use IT for Animation and how does IT really help.
5. Disappearing glaciers, rising sea levels, and why gravity is even more important than you think (Assistant Professor Emma Hill)
The most important point in this plenary session is that sea-level rise will not be the same everywhere. The sea-level rise 1.8mm each year. The speaker have showed us a diagram of the Earth and said that when the glaciers melt, not only will the sea levels rise but the land area which is covered with glaciers will rise. She showed us a module of the earth and that the glaciers are pushing down the land and causing the land to be lower than other parts of the world. A satellite that is called The Gravity Recovery and Climate Experiment (GRACE) obtains this module. Another thing I have learnt through the talk is that sea-level rise will be highest and farthest from the glaciers. For this, many of us who do not think that sea-level rise will affect us will actually be wrong. Therefore, we need to start planning ahead on finding a solution to solve the problem.
