Contacting the Mathematics Department

Mathematics Department operations are being performed via a mix of principally in-person and some remote means.

The Math Department's main telephone lines, at (212) 650-5346 and 5347, are being answered Monday through Thursday by in office staff in the Marshak building, MR 529. Hours of operation for all days are from 9am - 5pm.

On Fridays, however, the staff often operates remotely. As a result, calls to the department should then be directed to (347) 961-7667, which will generally be answered 9am-5pm.

Preferably, email your concerns and questions to math@ccny.cuny.edu, which is being monitored regularly.

Contacting Advisors and Program Administrators

For questions concerning registration, e.g. possible overtallies, please email the Math Dept at math@ccny.cuny.edu. In addition to indicating your preferred sections(s) for the course you are looking for, please be sure to include your Empl ID and telephone number (for a quicker back and forth about available sections).

Meet the Platonic Solids: Dodecahedron

The dodecahedron

The Platonic solids have been known since antiquity, and they play a prominent role in Plato's description of the physical world. The planar faces of each solid are identical polygons. Only equilateral triangles, squares and regular pentagons appear.

Although the platonic solids seem to be purely geometric objects, they embody a number of deep algebraic features. Their symmetries, for example, relate to the solution of polynomial equations of low degree.

If you would like to learn more about Platonic solids, you can start here.
