[1]#?DoctorWho? [2]?#?Trivia? Block Transfer Computations are
  the same as Quantum Mnemonics. They can't be done by computer
  because any computer that tried to execute the code would also
  be changed in the process of execution, preventing the execution
  of the code from completing. I was first introduced to it when I
  was between 8-10 years old and saw Logopolis, a planet inhabited
  by an advanced mathematical race that could Block Transfer
  Computations (or Quantum Mnemonics) in their minds.
  They successfully prevented the heat death of the Universe by
  transferring some of the Entropy into a pocket Universe... well,
  the Doctor did because the Logopolitans were destroyed by the
  Master... and I think it's somewhat their own fault as well.
  Anyway, now I'm understanding a little better why throughout
  school I was always like, "eh, math" and saw the ways formulas
  were done as old-fashioned and preferred translating them to
  BASIC code in my head while I was doing math tests in school.
  After all, programming *had* to be a step closer to Block
  Transfer Computations and I really wanted the ability to alter
  spacetime just by writing a few programs in my head. Such is the
  power of fiction smile emoticon I did well in math too, but
  never lost my disdain for "mathematics-as-we-do-it", always
  seeing it as primitive compared to what's yet to come
