He was buried in Canterbury, and the law named after him is quoted as his epitaph. C. Northcote Parkinson Cyril Northcote Parkinson (30 July 1909 – 9 March 1993) was a British naval historian and author of some 60 books, the most famous of which was his best-seller "Parkinson's Law" (1957), in which Parkinson advanced Parkinson's law, stating that "work expands so as to fill the time available for its completion", an insight which
D'Alembert's principle D'Alembert's principle D'Alembert's principle, also known as the Lagrange–d'Alembert principle, is a statement of the fundamental classical laws of motion. It is named after its discoverer, the French physicist and mathematician Jean le Rond d'Alembert. It is the dynamic analogue to the "principle of virtual work for applied forces" in a static system and in fact is more general than Hamilton's principle, avoiding restriction to holonomic systems. A holonomic constraint depends only on the coordinates and time. It does not depend on the velocities. If the negative terms in accelerations are recognized as "inertial forces", the statement of d'Alembert's principle
