#### Background Information:

Mathematics is arguably the most fundamental of all academic disciplines. Often called the universal language, mathematics underlies a great part of the physical sciences and also has important connections to computer science, philosophy, economics and business, music, and many other fields. At the same time, mathematics can be regarded as high art, well worth studying for its stark beauty alone. Contrary to beliefs that it is a static discipline, mathematics is currently in a period of explosive growth in its internal development and its applications, and in the use of technology to enhance and extend our understanding. At Juniata, we strive to equip our students to appreciate and participate in this exciting evolution. To this end, we are fortunate to enjoy close ties with the departments of Information Technology and Computer Science, Physics, and Accounting, Business, and Economics. Just as important, we have a close working relationship with the Education Department to support a strong preparation for teaching mathematics at the secondary level.
