Meet the Platonic Solids: Dodecahedron

From http://commons.wikimedia.org/wiki/Main_Page

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.

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).

Eligibility:

Reimbursable expenses:

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).

Please address questions to Prof. Hooper or Prof. Medvedev.
