Day 1 Reflection
Importance of Water- Dirty and Clean
There are many negative effects of dirty water. Dirty water can cause diseases such as cholera, typhoid fever and dysentery. These are life-threatening diseases. Pollution bothers us as its produces smell, causes infectious diseases and chronic health risks and has environmental, societal and economic effects. The whole of the world’s infrastructure spending growth is US$22970 billion for years 2003-2030 and asia itself has an infrastructure spending growth of US$9000 billion. The world is trying to use technology to break barriers. For example, membranes are used in NEWater plants for the cleansing of used water of water from water catchments.
Revolution of Microelectronics Technology
Due to supply chain of electronics, Asia becomes focal point for electronic companies. Proliferation of electronics drive global demand. The first Integrated Circuit )IC) was invented in 1958 and consisted of 1 transistor, 3 capacitors and 1 resistor. There are different types of Integrated Circuits; bio, radio, auto, info, nano, water/hydro, audio, video and energy. Electronics is scaling up to reach nanoscale while biology is scaling down.
Biomedical Engineering & Technology
Nanotechnology can help mankind in many ways. Nanotechnology can be used to change colour of contact lens and can be used for consumption of drugs. Smaller size for a fixed volume = Larger surface --> More energy. Nanotechnology has been used to create a material with ten times the strength of steel but only a fraction of the size. This material is called Carbon Nano-Tube (CNT). Its structure is similar to that of a spider web.
IT for Animation
Animation is an optical illusion of motion created by consecutive frames. There are 3 types of animation; stop motion, 2D animation and 3D animation. An example of 2D animation is Lion King which is the highest grossing 2D film in USA and has an estimated making cost of US$45 million while a 3D animation, Toy Story had a lower making cost of $30 million.
Disappearing glaciers, rising sea levels and why gravity is even more important than you think
A geodesist measures the shape and size of the Earth, its gravity field and how these things change over time. Sea level rise will not be the same everywhere and it’s only possible to measure a few glaciers from the ground. Sea level rise will be the highest farthest from glaciers.
The plenary session that leaves the deepest impression on me is the one on Disappearing glaciers, rising sea levels and why gravity is even more important than you think. What I like about it is that it tells very practical and useful information that has changed my way of thinking about gravity and rise of sea level. Originally, I thought that sea level was the same everywhere and sea level rise at melting glaciers would be the greatest. But, after sitting through the plenary session, I realised that sea level is not the same everywhere and that sea level rise would be the least nearest to melting glaciers and the greatest furthest away.
Day 3 Reflection
1. I chose this project because I felt that it would be a good head start for Term 3 when we are most likely going to learn about electrical engineering. I also felt that electrical engineering woud be fun as I felt the electrical circuits that we learnt in Primary school fun.
2. I am the secondary presenter in my group as I presented to my project mates and professor in the lab but not to the school. I am also the leader and provided assistance to my group mates.
3. We were supposed to finish our presentation slides by the end of Day 2 but we were not able to complete it by then and we were still not able to complete despite waking up earlier on Day 3. I decided to split the work up so each group member would do a different task like making circuit diagrams, typing out information on each of the components in an electrical circuit or taking photos/videos of components. We were also given extra time to complete our presentation.
4. Through this project, I/we discovered about basic units for electricity, formulae, components, how to put the components together and a lot more stuff. The basic units for electricity is voltage (V), current (I) and resistance (R). A formula is Ohm's law which shows that V = I x R. Some components are resistors and transistors.
5. The programme has instilled an interest for electronics in me and has built a foundation for future electronics education. I also know more about electronics that many of my classmates so I will have a head start in future lessons on electronics. I am also sure that some of the important information that I have learnt will not be taught to us in the near future.
6. I aspire to do future courses and workshops on electronics and go deeper into the area of electronics. I would also want to play around with more electrical components and how they affect a circuit. I hope that I can grow up and graduate with first class honours in the field of electronics.
