25% of 18th century science

According to historian Clifford Truesdell,

… in a listing of all of the mathematics, physics, mechanics, astronomy, and navigation work produced in the 18th century, a full 25% would have been written by Leonard Euler.

    He was number -exp(Pi*i)!

    Euler is 25%

    “Would have been written”?!?! Is that at all like “was written”? You know, Im pretty sure if no one in history ever contributed to science, I “would have” single handedly caught this world back up.

    I read it as “[If a hypothetical listing were created of] all of the mathematics, physics, mechanics, astronomy, and navigation work produced in the 18th century, a full 25% would have been written by Leonard Euler.”

  5. John Venier says:

    I read it like Johnny, too, but that leads to the question of metric. 25% of what? Books? Pamphlets? Pages? Words? Peer-reviewed journal articles? ;-)

    Then again, using the 80-20 rule, 80% of the valuable content is in 20% of the work, so maybe Euler is responsible for more than 80% of the valuable content in those fields :-D

    But seriously, although those are mighty fields, I think science ought to also include chemistry, metallurgy, biology, and geology at least, and maybe medicine, so perhaps it isn’t fair to credit Euler with 25% of science as a whole.

    According to me:

    … in a list of mathematics, physics, mechanics, astronomy, and navigation, a full 20% is the word, “navigation.”
