The second law of thermodynamics may be expressed in many specific ways, [25] the most prominent classical statements [26] being the statement by Rudolf Clausius (1854), the statement by Lord Kelvin (1851), and the statement in axiomatic thermodynamics by Constantin Carathéodory (1909). These statements cast the law in general physical terms ...
The Planck statement applies only to perfect crystalline substances: As temperature falls to zero, the entropy of any pure crystalline substance tends to a universal constant. That is, lim T → 0 S = S 0 {\displaystyle \lim _{T\to 0}S=S_{0}} , where S 0 {\displaystyle S_{0}} is a universal constant that applies for all possible crystals, of ...
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 and mathematical analysis of electricity, was instrumental in the formulation of the first and second ...
The history of thermodynamics is a fundamental strand in the history of physics, the history of chemistry, and the history of science in general. Due to the relevance of thermodynamics in much of science and technology, its history is finely woven with the developments of classical mechanics, quantum mechanics, magnetism, and chemical kinetics, to more distant applied fields such as ...

It might seem like a simple question. But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering. But that same ...
Planck radiation has a maximum intensity at a wavelength that depends on the temperature of the body. For example, at room temperature (~ 300 K), a body emits thermal radiation that is mostly infrared and invisible. At higher temperatures the amount of infrared radiation increases and can be felt as heat, and more visible radiation is emitted ...
Young adults are taking the supercommute into work, a trend that will only likely continue as return-to-office mandates from Amazon, JP Morgan, and others continue.. Molly Hopkins, age 30, has ...
