Vor einem Tag · Lord Kelvin. It is believed the "PNP" in his signature stands for "Professor of Natural Philosophy". Kelvin also wrote under the pseudonym "P. Q. R." William Thomson, 1st Baron Kelvin, OM, GCVO, PC, FRS, FRSE (26 June 1824 – 17 December 1907) [7] was a British mathematician, mathematical physicist and engineer born in Belfast. [8]
Vor einem Tag · Etymology and terminology The term zero-point energy (ZPE) is a translation from the German Nullpunktsenergie. Sometimes used interchangeably with it are the terms zero-point radiation and ground state energy. The term zero-point field (ZPF) can be used when referring to a specific vacuum field, for instance the QED vacuum which specifically deals with quantum electrodynamics (e.g ...
Vor 35 Minuten · William Thomson, or Lord Kelvin, as he became known after his ennoblement, made important contributions to thermodynamics, among other topics. He devised the first absolute temperature scale, i.e., a temperature scale that is independent of the physical properties of any specific substance and in which the zero of the scale equals “absolute zero”—the coldest possible temperature at which ...

Here is a place to discuss the study and application of Thermodynamics and Heat Transfer, as relates to physics, cosmology, chemistry, engineering, materials science, earth sciences and biology. Thermodynamics deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical), focused predominantly on equilibrium or quasi-equilibrium systems. Heat ...
Vor einem Tag · Geospatial data remains too hard to work with. It’s the domain of specialists, out of reach for most people and organizations. Thankfully a wave of new tools, formats, and data – like DuckDB, Geoparquet, and the Overture Maps Foundation – are making GIS easier.
