So Pentcho Valev obviously failes to understand the difference
between ideal circumstances and realistic circumstances, and
thus decides that the UNIVERSE IS INCONSISTENT.

Updated list of differences ignored by Pentcho Valev:
    - ideal circumstances vs. realistic circumstances,  <== NEW!
    - crackpots vs. people writing books fancied by crackpots,
    - rates vs. values,
    - a personal humorous musing vs. a common dogma,
    - children's books vs. inspired essays,
    - physicists vs. philosophers,
    - coordinate time vs. proper time,
    - invariance vs. constancy,
    - special relativity vs. general relativity,
    - teachers vs. hypnotists,
    - laymen vs. zombies,
    - a person being right vs. a theory being right,
    - students vs. imbeciles,
    - bad science vs. bad engineering,
    - bad engineering vs. bad cost management,
    - honing the foundations of a theory vs. fighting it,
    - physics vs. linguistics,
    - an article written in 1905 vs. a theory created in 1915,
    - understanding a book vs. turning its pages,
    - speed vs. relative (aka closing) speed,
    - doing algebra vs. randomly writing down symbols,
    - real life vs. a Usenet hobby group,
    - receiving a detailed reply vs. being ignored,
    - everyday concepts vs. scientific concepts in physics,
    - the three things that smell like fish,
    - inertial vs. non-inertial,
    - speed vs. velocity,
    - an article vs. a book,
    - relativity vs. disguised ether addiction,
    - algebra vs. analytic geometry,
    - kneeling down vs. bending over,
    - local vs. global,
    - a sycophant in English vs. in French,
    - a relation vs. an equation,
    - massive vs. massless particles,
    - a Mexican poncho vs. a Sears poncho,
   [ - implication vs. equivalence,  <== perhaps to be removed ]
    - group velocity vs. phase velocity,
    - science vs. religion
