• Bistromathics itself is simply a revolutionary
  new way of understanding the behaviour of
  numbers. Just as Einstein observed that space was
  not an absolute but depended on the observer's

  in time, so it is now realized that numbers are
  not absolute, but depend on the observer's
  movement in restaurants.

  number 1729 and remarked that the number seemed
  to me rather a dull one, and that I hoped it was
  not an unfavourable omen. "No," he replied, "it
  is a very interesting number it is the smallest
