Mathematics is essential to a clear and complete understanding of virtually all phenomena. The study of mathematics provides the ability to describe applied problems quantitatively and to analyze these problems in a precise and logical manner. This is a principal reason behind the strong demand for mathematicians in government and industry. Essentially all complex problems, whether physical, social, or economic, are solved by designing a mathematical model, analyzing the model, and determining computational algorithms for an efficient and accurate approximation of a solution. Each of these phases is mathematical in nature. For example, if a problem deviates from a standard form, a mathematician should be able to adjust appropriately the usual mathematical treatment for the problem to accommodate for the deviation. In this case mathematical training provides a practical preparation for a career in today's changing world. Moreover, it is especially valuable since it is an education that equips one to continue to adapt to new situations.
Mathematicians typically are employed as applied mathematicians in their specialty areas. Approximately 60 percent of our recent mathematics graduates have gone into government and industry, while 20 percent have gone to graduate school, and 20 percent have gone into teaching. There are four different paths or options that a student may follow towards a B.S. in Mathematics: 1) the Traditional Option; 2) the Applied and Computational Mathematics Option (ACM); 3) the Applied Discrete Mathematics Option (ADM); and 4) the Educational Option (MAED).
The Traditional Option, as its name implies, yields a broad and flexible background in mathematics. The other three options are more specialized. The ACM is designed for students who are confident that they want to have an applied mathematics career in an area closely associated with physics or some form of engineering. The ADM is designed for students who plan to have an applied mathematics career in an area closely associated with computer science, statistics, or actuarial science. The Education Option is designed for students who want to teach high school mathematics.
Often students will begin their studies in the Traditional Option and later change to one of the other three options when they become more sure of the path they wish to pursue. One, however, can acquire many aspects of the three specialized options within the Traditional Option, because it also requires some degree of specialization in an applications area and provides career development features. The three specialized options are each less general, but bring particular career paths into sharper focus. Each of the four options provides an excellent foundation for graduate study, either in mathematics or in an applications area. Handbooks for each of the options, as well as mathematics career information, are available upon request.
Approximately $18,000 in Hatcher, Morris, Layman, Rollins, Steeneck, Caldwell, and Roselle scholarships is awarded annually to mathematics majors at Virginia Tech: $7,500 for incoming freshmen and $8,500 for continuing undergraduates. Information on the scholarships is available from the scholarship chairman in mathematics.
The Cooperative Education Program is also available to qualified candidates, and students wishing to mix practical experience with their formal course studies are encouraged to investigate this option.
The mathematics department firmly believes that mathematics is not only useful and beautiful, but also fun. The department sponsors student chapters of MAA (Mathematical Association of America) and Pi Mu Epsilon (the national mathematics honorary society). As well as social activities, these groups sponsor speakers to talk on how mathematics is used in their work. Each fall, Virginia Tech also sponsors an Eastern U.S. Regional Mathematics competition. Each spring all freshmen and sophomores at Tech are invited to compete for prizes in a local mathematics contest. In addition, students (not all of whom are mathematics majors) annually receive organized preparation and compete in the nationwide William Lowell Putnam Competition. Individual undergraduate research projects are available to talented students, and a research prize is awarded. Outstanding seniors in the mathematics options are also recognized each year at graduation.
The Honors Program in Mathematics provides outstanding undergraduate majors the opportunity for an enriched academic environment. Through honors courses, an honors project, individual association with the faculty and honors advisors, and other perquisites; the honors student in mathematics enjoys a valuable advantage in the undergraduate experience. Moreover, in coordination with the head of Mathematics and the dean of Arts and Sciences, the honors student may design her/his own individual set of graduation requirements.
In addition to the four undergraduate-degree options, the department also offers the M.S. and Ph.D. (See the Graduate Catalog.) Moreover, for qualified students, a combined program is available that leads to both a B.S. and an M.S. in mathematics. In addition, students in the Education Option may choose between a four-year B.S. program and a five-year program that also includes an M.A. in education. This program saves nearly a year from the usual time required for a B.S. and an M.S.
The minor is designed to provide recognition for those students who take a program of study in mathematics above the normal requirements of their disciplines.
The mathematics department has also joined with the departments of computer science and statistics to offer a course which provides an interdisciplinary approach to the study of mathematical sciences. (Please see "Mathematical Sciences" in this catalog section.)
