    Kelvin also wrote under the pseudonym "P. Q. R." William Thomson, 1st Baron Kelvin (26 June 1824 – 17 December 1907 [ 7 ]) was a British mathematician, mathematical physicist and engineer. [ 8 ][ 9 ] Born in Belfast, he was the professor of Natural Philosophy at the University of Glasgow for 53 years, where he undertook significant research ...

  3. Vortex theory of the atom - Wikipedia

    en.wikipedia.org/wiki/Vortex_theory_of_the_atom

    The vortex theory of the atom was a 19th-century attempt by William Thomson (later Lord Kelvin) to explain why the atoms recently discovered by chemists came in only relatively few varieties but in very great numbers of each kind. Based on the idea of stable, knotted vortices in the ether or aether, it contributed an important mathematical legacy.

    The kelvin now only depends on the Boltzmann constant and universal constants (see 2019 SI unit dependencies diagram), allowing the kelvin to be expressed exactly as: [2] 1 kelvin = ⁠ 1.380 649 × 10 −23 / (6.626 070 15 × 10 −34)(9 192 631 770) ⁠ ⁠ h Δν Cs / k B ⁠ = ⁠ 13.806 49 / 6.091 102 297 113 866 55 ⁠ ⁠ h Δν Cs / k B

    In 1848, William Thomson, 1st Baron Kelvin (commonly known as Lord Kelvin) established the concept of absolute zero, the temperature at which all molecular motion ceases. In 1849, Louis Pasteur discovered that the racemic form of tartaric acid is a mixture of the levorotatory and dextrotatory forms, thus clarifying the nature of optical ...

    en.wikipedia.org/wiki/Age_of_Earth

    In 1862, the physicist William Thomson, 1st Baron Kelvin published calculations that fixed the age of Earth at between 20 million and 400 million years. [19] [20] He assumed that Earth had formed as a completely molten object, and determined the amount of time it would take for the near-surface temperature gradient to decrease to its present value.

  8. Kelvin–Helmholtz instability - Wikipedia

    en.wikipedia.org/wiki/Kelvin–Helmholtz_instability

    The Kelvin–Helmholtz instability (after Lord Kelvin and Hermann von Helmholtz) is a fluid instability that occurs when there is velocity shear in a single continuous fluid or a velocity difference across the interface between two fluids. Kelvin-Helmholtz instabilities are visible in the atmospheres of planets and moons, such as in cloud ...
