Before the word 'physicist' was coined by William Whewell in 1840, people investigating the physical world called themselves natural philosophers, a title that covered chemistry, biology and what would later separate out as physics under one broad umbrella. As universities created dedicated physics chairs and journals through the nineteenth century, the older, broader title faded out of use.
Natural philosopher已不复存在。这里整理是什么消灭了它，以及哪个职业接手了那份工作。
1687–1900
Classical physics matures
Newtonian mechanics extended into thermodynamics, statistical mechanics and, through Faraday's experiments and Maxwell's equations, a full theory of electromagnetism that predicted light itself was an electromagnetic wave. The word 'physicist' was coined only in 1840, by the English polymath William Whewell, as universities began creating dedicated chairs and journals for a discipline that had outgrown the older label of natural philosophy.
当时还发生了什么
1831
Faraday discovers electromagnetic induction
Michael Faraday shows that a changing magnetic field induces an electric current, the principle behind every electric generator, transformer and motor built since.
1865
Maxwell unifies electricity, magnetism and light
James Clerk Maxwell publishes equations showing that electricity and magnetism are two faces of one field, and that light itself is an electromagnetic wave travelling at a predictable speed.
1900
Planck introduces the quantum
Max Planck shows that a hot object's radiation only matches observation if energy is emitted in discrete packets, or quanta — an assumption he treats as a mathematical trick that turns out to describe something real.
1905
Einstein's miracle year
Working as a patent clerk in Bern, Albert Einstein publishes four papers in a single year on special relativity, the photoelectric effect and Brownian motion, reshaping physics' basic concepts of space, time, mass and light.
那份工作如今在哪里
Derives and tests the mathematical laws governing matter, energy, space and time, from a lone chalkboard to a 3,000-author particle-collider paper.
