Math Ideas Expressed in Limericks

When you have time, a fascinating website to visit and browse is OEDILF  -- The Omnificent English Dictionary in Limerick Form.   

Here is a sample:    

      cuproid by Recumbentman (Limerick #89414)

            Tetrahedrons are bounded by four
            Triangular faces, no more.
            If on each one of those
            A pyramid rose,
            A cuproid would then take the floor.   

The name cuproid, derived from copper, denotes a solid shape under twelve triangular faces, organised as described above. It occurs in the mineral tetrahedrite, a sulphide of copper and antimony.    Here on the dictionary's home page -- OEDILF  -- The Omnificent English Dictionary in Limerick Form   -- one may search for terms and their limerick definitions and for limerick authors.
