Meet the Platonic Solids: 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.

Graduate Application Fee Reimbursements
Through a generous gift from the Rich family, the Mathematics Department is able to reimburse some of the costs of undergraduate mathematics majors and Master’s mathematics students when applying to graduate (Master’s or PhD) programs which the students are considering enrolling in after graduation from CCNY.
We can reimburse up to $500 per student (though we may be able to reimburse more depending on the number of students applying for reimbursement).
- You must be an undergraduate mathematics major or mathematics Master's student, and graduate (or be scheduled to graduate) in the Spring 2016, Fall 2016 or Spring 2017 semesters.
- You must have at least a 3.0 average across mathematics courses taken at CCNY.
- You must have a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). (If you do not have one of these then we may not be able to process your reimbursement. Contact Jason Redman to inquire about reimbursement in this case.)
- You must apply for reimbursement by May 15, 2017.
- Application costs to graduate programs.
- Costs of sending GRE results to graduate programs.
We require receipts (which must include method of payment, e.g., the last four digits of a credit card) for proof of payment.
Requesting reimbursement: Students need to fill out this Application Fee Reimbursement Form, attach receipts from all allowable expenses incurred, and give this all to Jason Redman. The forms can be dropped off in person to Jason at his office (NAC 8/201) or sealed in an envelope addressed to Jason and turned in to the Math Office (NAC 8/133). It is okay to apply more than once (for distinct expenses).
