They also involved the combination of tangential and radial displacements, which Newton was making in the 1660s. The lesson offered by Hooke to Newton here, although significant, was one of perspective and did not change the analysis. [18] This background shows there was basis for Newton to deny deriving the inverse square law from Hooke.
Locke quotes Hooker numerous times in the Second Treatise of Civil Government and was greatly influenced by Hooker's natural-law ethics and his staunch defence of human reason. As Frederick Copleston notes, Hooker's moderation and civil style of argument were remarkable in the religious atmosphere of his time. [ 20 ]
Hooke's 1674 Gresham lecture, An Attempt to Prove the Motion of the Earth by Observations (published 1679), said gravitation applies to "all celestial bodies" [115] and restated these three propositions. [116] Hooke's statements up to 1674 make no mention, however, that an inverse square law applies or might apply to these attractions.
In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.
This was followed in 1676 by Robert Hooke's first statement of Hooke's Law, providing a scientific understanding of elasticity of materials and their behaviour under load. [ 9 ] Eleven years later, in 1687, Sir Isaac Newton published Philosophiae Naturalis Principia Mathematica , setting out his Laws of Motion , providing for the first time an ...
John Locke's portrait by Godfrey Kneller, National Portrait Gallery, London. John Locke (/ l ɒ k /; 29 August 1632 – 28 October 1704 ()) [13] was an English philosopher and physician, widely regarded as one of the most influential of the Enlightenment thinkers and commonly known as the "father of liberalism".
Sidney Hook (December 20, 1902 – July 12, 1989) was an American philosopher of pragmatism known for his contributions to the philosophy of history, the philosophy of education, political theory, and ethics.
Legal history or the history of law is the study of how law has evolved and why it has changed. Legal history is closely connected to the development of civilisations [1] and operates in the wider context of social history.
