Writing about web page http://www.crank.net/maths.html
The internet has provided a wonderful outlet for cranks from self-appointed messiahs such as David Icke (who claims the Pope, the Queen and George Bush are literally baby eating lizards) through to the curious delights of Gene Ray's 4 dimensional time cube.
Recently I stumbled across the website CRANK DOT NET which provides the service of "presenting Web sites by and about cranks, crankism, crankishness, and crankosity". Surprisingly there is an entire section devoted to what one might call Maths Cranks – brave souls fighting the conspiracy of teachers and professional mathematicians who have been lying to us all these years that two and two make four, and you cannot divide by zero.
Take the first link, for example, called Zim Mathematics in which we learn that "All Mathematics is equal" although the meaning of this mysterious sentiment is not elaborated on. Navigating the website leads to many a bizarre equation. For example, I defy anyone to make sense of anything on the Quantity = Quality page, which contains such exotic incoherency as…
Quan × Quan => Qual ; Unsubordinate Fact
(N1 + N2 + N3) × (A + B + C)
A = Not A
1 × 1 = > 1x
1 Sheep + 1 Ram ( Sheep + Not Sheep + Ram + Not Ram)
(That last has to be my favourite.)
