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 was a British mathematician, mathematical physicist and engineer. [7][8] Born in Belfast, he was the professor of Natural Philosophy at the University of Glasgow ...
Kelvin water dropper. The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's ...
Notable critics included Simon Newcomb, Lord Kelvin, and the chief engineer of the US Navy, George W. Melville, the latter of whom described flying machines as "wholly unwarranted, if not absurd". [4] After five years of preparations, aviation pioneer Samuel Langley was ready to test out his Aerodrome on October 7, 1903.
The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
The 19th century British scientist Lord Kelvin first developed and proposed the scale. [5] It was often called the "absolute Celsius" scale in the early 20th century. [6] The kelvin was formally added to the International System of Units in 1954, defining 273.16 K to be the triple point of water.
Most cite this book as the starting point for thermodynamics as a modern science. (The name "thermodynamics", however, did not arrive until 1854, when the British mathematician and physicist William Thomson (Lord Kelvin) coined the term thermo-dynamics in his paper On the Dynamical Theory of Heat.)

The product of the mass of a body into the square of its velocity may properly be termed its energy. [4] Gustave-Gaspard Coriolis described "kinetic energy" in 1829 in its modern sense, and in 1853, William Rankine coined the term " potential energy." It was argued for some years whether energy was a substance (the caloric) or merely a physical ...
