General Information and Advice

Why Choose Mathematics?

Mathematics in general plays a crucial role in our attempts to understand the world around us. We see this demonstrated in the extensive use of mathematical models in the theoretical and applied sciences: from physics and chemistry through to engineering, operations research, computer science, information theory and economics. Many important models are based on modern mathematical research. Examples from applied mathematics research are the application of stochastic ODE's in finance and physics, our increased understanding of chaotic behaviour and its application to a wide range of physical phenomena and the development of improved large-scale numerical techniques used on an everyday basis for applications ranging from weather prediction to models of artificial hearts. Examples from pure mathematics research are the application of number theory to cryptography, applications of singularity theory and group theory to symmetry-breaking and bifurcation in the engineering sciences, the application of category theory to theoretical computer science and the recent developments of general field theories in mathematical physics based on the most profound work in complex analysis and algebraic geometry.

As quantitative reasoning and mathematical modelling techniques extend further into the medical and social sciences, the humanities and all areas of finance, there is an increasing demand for mathematically competent workers in these fields and for teachers of specific mathematical skills in both general and adult education. Employers increasingly value the logical thinking and problem solving skills that are developed by studying mathematics.

Pure Mathematics and Applied Mathematics

There are two separate disciplines within the general subject area – Pure Mathematics and Applied Mathematics. You may choose units from either or both disciplines.

• If you enjoy problem solving, working with computers and using your mathematics to deal with real applications in science, engineering, economics and biology then you should consider enrolling in some Applied Mathematics units. You will attain a high level of mathematical expertise and a good deal of practical computer experience, both of which will stand you in good stead in a wide variety of possible careers, for example in computing, finance, telecommunications and mathematics research.
• If you appreciate the elegance of conceptual reasoning, or enjoy the challenge of abstract problems, you should consider enrolling in some Pure Mathematics units. They are wise choices not only for those whose principal interest lies in mathematics itself, but for all who wish to extend their reasoning ability: many students whose main interests lie in other disciplines find Pure Mathematics an ideal second major. A wide variety of pure units are offered, at both Advanced and Normal levels, covering all major branches of mathematics.

Why Choose Statistics?

Statistical techniques are employed in almost every aspect of daily life. These techniques are basically designed for data analysis and enable, for example, governments to plan our future through use of census data, businesses to forecast consumer demand for products, medical researchers to determine effectiveness of drugs, engineers to establish quality control standards, economists to use various indices of economic growth to attempt predictions of the future state of the economy, agricultural scientists to assess and compare the qualities of various soil types or strains of wheat or types of fertilizers and so on. The three facets of statistics are data analysis, probability modelling and statistical inference. Senior Statistics units provide the opportunity for further study in each of these areas.

As a result of the demand for statistical analysis across a broad spectrum of human endeavour and the ever increasing use of computers in data analysis, there is a growing demand for people trained in statistics both in the private and public sectors. This trend is likely to continue. Modelling and forecasting skills which are taught in the Senior Statistics courses are important in the areas of marketing, banking, finance and scientific research. Also, statistics will be useful for those contemplating a career in teaching. A major in statistics is always received positively by prospective employers as a relevant, useful area of training for potential employees.

How Many Units of Study Should You Choose?

To satisfy the B.Sc degree regulations, each Science student must take at least 24 credit points of Senior (third year) units in a single Science subject Area, such as Mathematics or Statistics. This subject area is then termed a major for that student. Note that the subject area of Mathematics encompasses both Pure and Applied Mathematics, and is separate from the subject area of Statistics.

Very many students take two majors in their third year; for example, majors in Mathematics and Statistics, Mathematics and Computer Science, Statistics and Psychology, Mathematics and Physics, Mathematics and Chemistry, or a double major in Mathematics (48 credit points of Senior Mathematics units).

Each Senior unit of study offered by the School of Mathematics and Statistics is worth 6 credit points. To major in Statistics you must therefore complete four Senior Statistics units. To major in Mathematics you must complete four or more Senior Mathematics units. (A double major consists of eight Senior Mathematics units.) You may choose Pure Mathematics, Applied Mathematics or a mix of the two.

If you are not majoring in Mathematics or Statistics, you can still choose any number of Senior level units of study from either area to complement your other subjects: see below for some recommendations.

Computational Science

Computational science (COSC) is an interdisciplinary major comprising units of study offered by several Schools and Departments in the Faculty of Science. In particular, MATH3076 Mathematical Computing and MATH3976 Mathematical Computing (Adv) are Senior Core units in the Major. See the COSC major description for more details.

Financial Mathematics and Statistics

The major in Financial Mathematics and Statistics combines selected units from the subject areas of Statistics and Mathematics. This program is designed for students in double degrees who are interested in pursuing a career in the financial sector, but because of degree restrictions can only take a single Science major. It is also available for any student in the B.Sc. with an interest in finance and forecasting, and caters for those who wish to include Senior units other than Mathematics and Statistics units in their degree or who wish to complete a second major outside the School of Mathematics and Statistics. (Note that students in the B.Sc who wish to specialize in this area can include all the units in the Financial Mathematics and Statistics program while completing a major in Mathematics or Statistics, or a major in Mathematics and a major in Statistics.)

Students planning to take the Financial Mathematics and Statistics major and who are considering Honours should consult either the Mathematical Statistics 4 Coordinator (Uri Keich, Carslaw room 821, email st4coord@maths.usyd.edu.au) or the Applied Mathematics 4 Coordinator (Robert Marangell, Carslaw room 720, email am4coord@maths.usyd.edu.au) before finalizing their electives.

To obtain a major in Financial Mathematics and Statistics a candidate will have to successfully complete the Senior units of study listed below. All of the core units must be completed, and at least one of the electives.
