Inch-Pound
The inch-pound (in·lbf) is a unit of torque or energy, representing the force of one pound applied at the end of a one-inch lever arm.
History/Origin
The inch-pound has been used primarily in the United States and other countries that employ imperial units, originating from the traditional use of inches and pounds in mechanical and engineering contexts, with its formal recognition dating back to the 19th century.
Current Use
It is commonly used in engineering, automotive, and mechanical applications to measure torque and energy, especially in contexts where imperial units are standard.
Rydberg Constant
The Rydberg constant (Ry) is a physical constant that represents the highest wavenumber (inverse wavelength) of any photon in the hydrogen atom's emission spectrum, used to calculate spectral lines.
History/Origin
Named after the Swedish physicist Johannes Rydberg, the Rydberg constant was introduced in the late 19th century as part of Rydberg's formula to describe the spectral lines of hydrogen, significantly advancing atomic physics.
Current Use
The Rydberg constant is used in quantum physics and spectroscopy to determine energy levels of hydrogen and other hydrogen-like atoms, and in calculations involving atomic spectra and quantum mechanics.
