1687 Jul 5, The first volume of
Isaac Newton's "Philosophiae naturalis principia mathematica"
("Mathematical Principles of Natural Philosophy") was published in
Latin by Edmund Halley. His invention of differential and integral
calculus is here presented. Here also are stated Newton’s laws of
motion, that obliterated the Aristotelian concept of inertia. 1)
Every physical body continues in its state of rest, unless it is
compelled to change that state by a force or forces impressed upon
it. 2) A change of motion is proportional to the force impressed
upon the body and is made in the direction of the straight line in
which the force is impressed. 3) To every action there is always
opposed an equal reaction. Book Three of the Principia opens with
two pages headed "Rules of Reasoning in Philosophy." There are four
rules as follows: 1) We are to admit no more causes of natural
things than such as are both true and sufficient to explain the
appearances. [A restatement of Ockham’s Razor: "What can be done
with fewer is done in vain with more."] 2) Therefore to the same
natural effects we must, as far as possible, assign the same causes.
3) The qualities of bodies which are found to belong to all bodies
within the reach of our experiments, are to be esteemed the
universal qualities of bodies whatsoever. 4) In experimental
philosophy we are to look upon propositions inferred by general
induction from phenomena as accurately or very nearly true
notwithstanding any contrary hypothesis that may be imagined, till
such time as other phenomena occur, by which they may either be made
more accurate, or liable to exceptions.
