Reflections
I read the 1907 original ‘An Episode of Flatland’ by Charles H Hinton in James R Newman’s 1956 collection ‘The World of Mathematics’. It did not impress me. A K Dewdney’s book ‘The Planiverse: computer contact with a two-dimensional world’ from 1984 on the other hand impressed me a lot. Now the two dimensions have reached the cinemas and will reach your download folder if you buy the 30 minute film online.
