WE ALREADY have solid, liquid, gas, plasma and Bose-Einstein condensate. Now it seems we may be on the verge of discovering a whole host of new forms of matter - all based on mathematics.

He made the discoveries while researching the field of topology - the study of the properties that objects share because of their shape.
