Today was a really good day! Everything had gone smoothly and I had little to worry about. Everything was under control.
0900 - 0945: Further Mathematics Line A Re-Test
1030 - 1200: Computing lesson (Data Representation)
1245 - 1700: Visit to the National University of Singapore (Mathematics Exhibition)
The highlight of the school day was the visit to NUS. I got to visit my dream faculty in my dream school. Isn’t that great? I felt joy for the first time in many weeks.
During the pre-tour lecture at NUS, I got to learn about Mathematics in Modern Society. The speaker was Associate Professor Goh Say Song, Department of Mathematics, National University of Singapore. The outline of the lecture is an introduction, followed by careers in Mathematics, applications of Mathematics, wavelets in image and video compression and the Department of Mathematics in NUS.
During the introduction, I learnt that the reasons for studying Mathematics are that it is the “foundation and language of scientific reasoning”; it “trains our analytical skill and logical reasoning”; it has many “applications in sciences, technologies, engineering, computing, economics” etc. Mathematics has been applied in movies such as Good Will Hunting and A Beautiful Mind. It has also been applied in novels such as The Da Vinci Code and Digital Fortress.
There are many careers in Mathematics. Contrary to popular myth that “a degree in Mathematics can only lead to a teaching career”, “a degree in Mathematics can lead to many possible careers”. Some of these careers include:
- Operations Research Analyst
- Financial Analyst/Planner
- Systems Analyst
- Software Engineer
- Computer Programmer
- Educator
- Mathematician
- Administrator
An Operations Research Analyst deals with problems on strategy, scheduling and inventory control. He or she uses mathematical models to help large organisations to operate efficiently. Some examples of these organisations include SIA and PSA.
Financial Analysts study financial trends and apply mathematical instruments to financial analysis. They can be found in banks, insurance companies, etc.
A Systems Analyst handles the processing, analysis and communication of digital information, using mathematical methods for efficient representation of digital information and computer security.
Next, applications in Mathematics include:
- Making movies come alive
- Listening to music
- Deciphering DNA
- Experimenting with the heart
- Defeating disease
- Designing aircraft
- Securing Internet communication
- Storing fingerprints
- etc
The mathematicians at NUS have been working on a project to develop an image and video compression technology termed wavelets. This technology is an improvement on available technology such as JPEG, GIF and other image compression standards and also MPEG2, MPEG4, DIVX and other video compression methods. It allows parts of the image or frame of video to be of a higher quality than the rest of the media to save disk space. These parts are termed as frame-of-interest and region-of-interest. I discovered that the technology allowed video to be compressed to a much smaller size (on average 100 times smaller) and somehow still retain 75% of its original quality, whereas technologies like MPEG2 retains only 50% of the original quality with a greater file size. This has great potential as people can now email home videos and photographs to their loved ones without having to worry about disk space constraints.
The lecture concluded with an introduction to the Department of Mathematics in NUS. The Department of Mathematics is split into Pure Mathematics and Applied Mathematics. Under Pure Mathematics, available subjects include algebra, analysis, geometry, probability and other “traditional” topics. Under Applied Mathematics, the subjects available include coding theory, cryptography, computational biology, financial mathematics, mathematical physics, operations research, wavelets and many more. The academic programmes offered include B.Sc./B.Sc. (Hons) in Mathematics/Applied Mathematics/Computational Finance and M.Sc./Ph.D in Mathematics (woah!).
After the lecture, we were led into the Department of Mathematics building where many exhibitions were held in computer labs. We were shown how wavelet technology works, how mathematics can be applied to everyday problems such as the most efficient route to take for mail delivery, how to design the most productive assembly line, mathematics used to discover n-dimensional space etc.
After the visit, our class decided there and then to have a class outing to have dinner at Plaza Singapura. We went there by taking a bus to Buona Vista MRT Station and taking the MRT to Dhoby Ghaut MRT Station. Once there, we decided to have our meal at Burger King. I had a wonderful time with my classmates while we travelled, discussing about the things we learnt during the visit and conjecturing our very own theories. At Burger King, I satiated my hunger with a Whopper and a small Coca-Cola.
After dinner, I went with some of my classmates to Bishan Junction 8 to watch a movie entitled A Cinderella Story. It was a nice show which reflects a lot of the original story but with an urban twist. Instead of losing the glass slipper, Cinderella lost her mobile phone. Small discrepancies aside, I feel that the true focus of this movie lies in the overall theme of standing up for one’s independence and choosing one’s way of life. I think that this is especially pertinent to Singaporean youth as I feel that young people like me are not making decisions for themselves but instead choose to follow the wishes and decisions of grown-ups. This might be a stereotypical view, but it certainly applies to myself, hence please do not be offended if you do not agree with my opinion.
A day of excitement ends. May the days ahead be filled with hope and endless surprises. Thank you for enduring through this, you are a great listener (reader) indeed.
