[6] [7] As the name "Magnum" implies, it was a fairly large device at 4.5 inches in diameter—about 1.5 inches more than Fowler's average non-Magnum-series calculators. [8] The large design meant that much larger calculations could be performed on it, "to four, and sometimes five, significant figures," according to the instruction manual. [6]
Tube micrometers have a cylindrical anvil positioned perpendicularly to a spindle and is used to measure the thickness of tubes. Micrometer stops are micrometer heads that are mounted on the table of a manual milling machine, bedways of a lathe, or other machine tool, in place of simple stops. They help the operator to position the table or ...
The first model to use this approach was the Bernal–Fowler model published in 1933, [21] which may also be the earliest water model. However, the BF model doesn't reproduce well the bulk properties of water, such as density and heat of vaporization , and is thus of historical interest only.

The Darwin–Fowler method has been treated in the texts of E. Schrödinger, [3] Fowler [4] and Fowler and E. A. Guggenheim, [5] of K. Huang, [6] and of H. J. W. Müller–Kirsten. [7] The method is also discussed and used for the derivation of Bose–Einstein condensation in the book of R. B. Dingle. [8]
Fowler–Nordheim theory predicted both to be consequences if CFE were due to field-induced tunneling from free-electron-type states in what we would now call a metal conduction band, with the electron states occupied in accordance with Fermi–Dirac statistics. Oppenheimer had mathematical details of his theory seriously incorrect. [15]
They are also known as Bernal–Fowler rules, after British physicists John Desmond Bernal and Ralph H. Fowler who first described them in 1933. [ 1 ] The rules state each oxygen is covalently bonded to two hydrogen atoms, and that the oxygen atom in each water molecule forms two hydrogen bonds with other water molecules, so that there is ...
