1023 days prior, I began a voyage through the progression of physics, tracing its origins from Aristotle\u2019s \u03c4\u1f70 \u03c6\u03c5\u03c3\u03b9\u03ba\u03ac to the crucial moment when the term “physics” embraced its contemporary meaning in 1715. In this sixty-fourth episode, we arrive at that point. At first, I investigated the etymology of “physics” and how it transformed over the centuries, culminating in its present definition.<\/p>\n
The current application of “physics” is undoubtedly linked to the release of Newton’s *Principia.* Although “Natural Philosophy” takes center stage in its title, it was the “Mathematical Principals” chapter that signified a break from Aristotle’s viewpoint. Aristotle held that the natural world couldn’t be represented mathematically since numbers aren’t natural entities. Consequently, mathematics was confined to mixed sciences like astronomy and optics. Nevertheless, Newton’s portrayal of nature was fundamentally mathematical, a fact that faced critique from contemporaries like Huygens and Leibniz for its absence of a physical explanation for gravity.<\/p>\n
Despite early critiques, Newton\u2019s mechanics gradually prevailed, evolving into what we call classical or Newtonian mechanics. However, this contemporary interpretation strays from Newton\u2019s initial discoveries. Mathematicians, especially in continental Europe, supplanted Newton’s Euclidian geometry with Leibniz\u2019s calculus, ultimately embracing Lagrange’s notation. This transition faced resistance in England due to national pride, preserving Newtonian analysis.<\/p>\n
Newton amalgamated celestial and terrestrial mechanics, inspired by the works of Kepler, Borelli, Stevin, Beeckman, Galileo, Descartes, Huygens, and others, presenting a mathematical account for motions on Earth and in the skies. Nonetheless, gaps persisted, such as his comet theory, which was later improved upon by Edmond Halley.<\/p>\n
Throughout the 18th century, Newton\u2019s principles underwent expansion and refinement, particularly beyond Britain. The Bernoullis and Euler in Switzerland, alongside Lagrange, Laplace, Legendre, d’Alembert, Maupertuis, and \u00c9milie du Ch\u00e2telet in France made remarkable contributions. Daniel Bernoulli delved into kinetic theory and hydrostatics, while Laplace addressed the Moon’s orbital conundrum in his piece *Trait\u00e9 de m\u00e9canique c\u00e9leste.*<\/p>\n
Notable progressions in mechanics featured the notions of energy and work. Newton proposed kinetic energy as mv, yet Bernoulli and Leibniz suggested mv\u00b2. Gravesande\u2019s experiments bolstered the latter, which \u00c9milie du Ch\u00e2telet validated theoretically. The contemporary view of work, the transfer of energy through force and displacement, was first introduced by Coriolis and Poncelet in the 1820s.<\/p>\n
Throughout the 18th century, Lavoisier articulated the law of conservation of mass. By the 19th century, classical physics, structured on Newton\u2019s principles, had mostly been established. Although Newton advanced the fields of optics and magnetism, these subjects were only integrated into physics with the contributions of Faraday and Maxwell on electromagnetism. Maxwell\u2019s Equations, enhanced by Heaviside, heralded the waning of Newtonian physics, paving the way for Einstein’s theory of relativity.<\/p>\n","protected":false},"excerpt":{"rendered":"
