h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Mathematics is only relevant to the subject of reality in its total deviance from reality. Hyperdynamic maths, and non-linear mathematics are primarily concerned with time travel and therefore have no basis in reality.
Lower level maths, it is well known, have caused bloody conflicts throughout history. When once a fruit shop short-changed the navigator Abdel Tasman he initiated Jihad that wiped out all life on our planet. This may be false as the only person to report the death of everyone on Earth was alive at the time.
