Why Choose a Mathematics-Related Profession ?

Mathematics teaches patience, discipline, and step-by-step problem-solving skills. For those with a substantial background in mathematics, an unlimited number of career opportunuities are available. According to Jobs Rated Almanac , a 1990 publication of World Almanac Books of New York, NY, careers that require a very strong background in mathematics were listed as the five "best" jobs. They were :
  • software engineer
  • actuary
  • computer systems analyst
  • computer programmer
  • mathematician
Almost all of the top fifty jobs in this "best" jobs list involved mathematical reasoning and knowledge. This list was the result of the comparison of two hundred fifty jobs classified according to :
  • income
  • future outlook
  • physical demands
  • job security
  • stress
  • work environment

A List of Professions

The following list briefly describes work associated with some mathematics-related professions :

IOI Workshop 2014/2015

Lim Li is currently attending the December '2014 IOI (International Olympiad in Informatics) Workshop held at Icube Building, School of Computing, every Monday, Wednesday and Friday, 10 am to 5 pm. The programme for the IOI workshop is found here.

In the past, the IOI workshops (also known as the NUS CS3233 Competitive Programming elective module) started in January. This December workshop which is conducted by ex-IOI participants, commenced about a year or two ago, to provide more training for IOI potentials and to select high school candidates for the CS3233 module, which is typically held from January to April. Both Lim Min and Lim Jeck had attended this workshop conducted by Dr Steven Halim before (refer to here and here). Participants who obtain Silver and above medal in the National Olympiad in Informatics (NOI) (refer NOI 2014 website) and who are Singapore Citizens or Permanent Residents will be invited to join the IOI workshop after the NOI prize presentation in March.

The workshop is structured and well organized. The lesson notes are available and an analysis of the workshop's training contests is done. For example, you can see the analysis of Day 1 contest here. Lim Li did a commendable job :)

Lim Li is also currently providing Math Olympiad training to a Primary 5 boy, every Sunday from 10 am to 12 noon (only for the November/December holidays). She is teaching him SMO Junior topics (Sec 1 and 2 Math Olympiad stuff), and also guiding him to tackle the more challenging SMOPS questions. More recently, she is giving Math tuition to a Sec 2 girl from an IP school.

Good Books and Resources for Mathematical Olympiad

Some people asked me to recommend good books/resources to prepare for Mathematical Olympiad (MO), such as the Singapore Mathematical Olympiad and the International Mathematical Olympiad.  As my kids don't read many books (not even Math books), I can't really recommend any good books.

IfeTahu (click it to refer to his post at Art of Problem Solving), a IMO 2014 participant from US team, has recommended the following MO books:

"101 Problems in Algebra", "102 Combinatorial Problems", "104 Number Theory Problems" by Titu Andreescu and Zuming Feng
"Number Theory - Structures, Examples and Problems" by Andreescu and Dorin Andrica
"Geometry Revisited" by H.S.M. Coxeter and S.L. Greitzer
"Plane Euclidean Geometry - Theory and Problems" by Christopher Bradley
"A Course in Combinatorics" by Wilson and Van Lint
"Enumerative Combinatorics" by Stanley
"Graph Theory" by Diestel covers difficult combinatorics for IMO level
"The Probabilistic Method" by Alon and Spencer "MOP 2006 Homework Problems" - This handout was used to train the US IMO 2006 Team, and it contains a lot of extremely difficult problems in algebra, number theory, geometry and combinatorics.

Some of the above books may be available on the Internet. Go google them.

Another way to improve your MO skills is to regularly visit Art of Problem Solving (AoPS, Lim Jeck's favorite website. He is "oneplusone" at AoPS ) to solve and post MO problems.

IMSO 2014 Singapore Team

The International Mathematics and Science Olympiad (IMSO) is an annual competition in Math and Science for primary school students. Since 2011, NUS High School has been appointed by the Gifted Education Branch (GEB), MOE to be the Lead Agency for IMSO, to select and train the IMSO national team.

From my understanding, students in the IMSO national team are typically offered Confirmed Offers from NUS High School under the Direct School Admission (DSA) exercise; they may even be awarded the 6-year NUS High scholarship if they choose to enrol in NUS High School from Secondary 1.

The Singapore team for the 11th IMSO comprises the following Primary 5 students. They are selected from the top 20 NMOS and SPSO winners, have undergone further training by NUS High and have done well in the respective selection tests.

Daniel Choo Zhenghao, ACS Primary
Mikail Firas Din s/o Abdul Jabar, ACS Primary
Boo Tse Yang Lucas, Nanyang Primary

QS University World Rankings 2014/2015

NUS, NTU up 2 spots in world ranking

By Sandra Davie Senior Education Correspondent

BOTH the National University of Singapore (NUS) and Nanyang Technological University (NTU) have moved up two places in the annual World University Rankings released this morning.

NUS moved up to 22nd place, and remains the top Asian university, while NTU moved up from 41st to 39th place.
The ranking by London-based education consultancy Quacquarelli Symonds (QS), which is into its 10th year, is widely consulted, including by prospective students and university professionals.
Institutions are ranked based on academic and employer reputation, student-faculty ratio, citations in academic publications per faculty, international faculty and student mix.
Academics are asked to rate institutions in their fields of specialisation.
This year's rankings took into account the opinions of 63,676 academics and 28,759 employers.
Overall, the Massachusetts Institute of Technology maintained its top spot, followed by Britain's University of Cambridge.
Imperial College London - because of its higher citations per faculty - was the biggest climber in the top 10, leapfrogging Harvard in the United States, University College London and Oxford in Britain to rank joint-second with Cambridge.
QS head of research Ben Sowter said that NUS' rise "signals a resolute long-term strategy, sustainable financial planning, investment in world-class facilities and leveraging Singapore's increasing desirability as a place to be".
He added: "NUS has further enhanced its research profile, strengthened its faculty-student ratio and resonated more strongly with employers this year.
NUS was rated ninth in the world by academics and 10th globally by employers.
Mr Sowter also noted that NTU is one of the fastest-climbing institutions.
"Strong progress in the citations per faculty indicator has driven NTU into the top 40 for the first time - and its new medical school has only just got going," he said. "Watch this space."
Singapore Management University, which is not included in the overall ranking, was ranked in the top 100 in social sciences and management, coming in at 93.
NTU stood at the 33rd spot and NUS, ninth best in the world.
Both NUS and NTU were also ranked among the top 10 universities for engineering and technology.
NUS president Tan Chorh Chuan said the university's growing reputation reflects its focus on nurturing, recruiting and retaining talent, the unrelenting pursuit of excellence and commitment to creating an environment where its staff and students can do excellent work.
"We will continue to innovate in education and research, so that the university will continue to contribute strongly towards the advancement of Singapore and the wider community in the years to come," he said.
Noted NTU president Bertil Andersson: "Competition within the world's top 50 is very stiff, so we are very pleased that we have climbed another two spots.
"With two Singapore universities high up in the global stakes, I think we all have much to be proud of."
He also pointed out NTU's 12th ranking in engineering last month in the Shanghai Jiaotong Academic Ranking of World Universities.
"From both these indices, it is clear that NTU's engineering is way up there with the world's best," said Professor Andersson.

Homemade Slurpee

Last week, Lim Li received $30 Capitavoucher for her SMO (Senior) prize. I used $20 Capitavoucher to buy the following slushy maker (it costs S$19.90) from Bugis BHG.

It is easy to make Ribena slurpee.
1. Place the slushy maker into the freezer until it is frozen (about 8 hrs, or overnight)
2. Pour in Ribena (or any chilled drink)
3. Put on the lid and squeeze, squeeze, squeeze! In less than a minute, you will have Ribena slurpee.
