Newton and Einstein
Today marks the death of Sir Isaac Newton (1642 - 1727), arguably the leading scientist of his era. Best known for his perception of gravity as a natural force, Newton proved his theory in Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy). Principia’s mathematical concepts provided the foundation for classical mechanics and much of the scientific research to come in the centuries following its publication. Principia was also instrumental in providing standards for rigor in scientific publications in general. His concepts were only disrupted in the early 20th century by Einstein’s quantum mechanics and the Theory of General Relativity. Coincidentally, today is also the day (1916) that Einstein published his Theory of General Relativity.
