We already have established that Pentcho Valev does not understand
and refuses to even try to understand the differences between:
    - physicists and philosophers,
    - coordinate time and proper time,
    - invariance and constancy,
    - special relativity and general relativity,
    - teachers and hypnotists,
    - laymen and zombies,
    - a person being right and a theory being right,
    - students and imbeciles,
    - bad science and bad engineering,
    - bad engineering and bad cost management,
    - honing the foundations of a theory and fighting it,
    - physics and linguistics,
    - an article written in 1905 and a theory created in 1915,
    - understanding a book and turning its pages,
    - speed and relative (aka closing) speed,
    - doing algebra and randomly writing down symbols,
    - real life and a Usenet hobby group,
    - receiving a detailed reply and being ignored,
    - everyday concepts and scientific concepts in physics,
    - the three things that smell like fish,
    - inertial and non-inertial,
    - speed and velocity,
    - an article and a book,
    - relativity and disguised ether addiction,
    - algebra and analytic geometry,
    - kneeling down and bending over,
    - local and global,
    - a sycophant in English and in French,
    - a relation and an equation,
    - massive and massless particles,
    - a Mexican poncho and a Sears poncho,
    - implication and equivalence,
    - group velocity and phase velocity,
    - science and religion

Exercise for the interested reader (by definition excluding Poncho):
Which differences are ignored in this specific message?
