The Principia is the basis for much of modern science.  It is swallowed hook, line and sinker by mathematicians and people in physics as a 'holy grail.'  It is a continuation of very old fashioned thinking, hooked on 'cause and effect' relationships, Aristotelian in nature.  One would think that modern science could see through this veil of antiquity, but seemingly has not yet had the courage to do so.<br><br>It is essential reading, however, so see how far 'science' has not moved for nearly 400 years.<br><br>This particular translation is of interest in that half of the book tries to explain and support the original text.  Bit too hard of a sell to justify Newton's arguments.  Again, it is a must-read for anyone seeking to understand the flaws of modern 'science.'
