ħ. I'm wondering for what purpose Planck's Constant is divided by 2•pi, and why specifically 2•pi? Also, the reduced planck's constant is h/2pi Why is this?
It is denoted by: Though a horizontal bar through the "h" would work fine as well. Is the constant h and the reduced constant ever thought to be a radius and circumference (of quanta)?

reduced proton Compton wavelength.

For example, the angular momentum of an electron bound to an atomic nucleus is quantized and can only be a multiple of h -bar. Symbol. 1.054571817e-34 J s. reduced Planck constant in eV s. 6.582119569e-16 eV s. reduced Planck constant times c in MeV fm. In this system the reduced Planck constant has a value of 1, so the value of the Planck constant is 2π. Planck's constant, #h#, is a commonly used physical constant. Examples would include, 1) de Broglie relation - #lamda = h/p# 2) Schrodinger equation - #(ih)/(2pi)(delpsi)/(delt) = -(h^2)/(8pi^2m)(nabla)^2psi + V(vec r,t)psi# 3) Commutator of #x# and #p_x# - #[x,p_x] = (ih)/(2pi)# How could Thorin and co. journey all the way to Erebor without discussing how to deal with Smaug? Today almost all important relationships in quantum mechanics, contain Planck's constant (or the reduced Planck's constant #h/(2pi)#).

How can I write a bold version of the reduced Planck constant, `\hbar`? I did try "hbar" but unfortunately it produces the output #hbar# 197.3269804 MeV fm. The constant is measured in Joules * Sec, how is joules*sec converted into an actual size. h/2pi looks like it could be a Radius. reduced Planck constant. Yes I'm referring to Dirac's Constant. This has caused the BIPM to consider a new definition for the kilogram. I'm wondering for what purpose Planck's Constant is divided by 2•pi, and why specifically 2•pi?

A modified form of Planck’s constant called h -bar (ℏ), or the reduced Planck’s constant, in which ℏ equals h divided by 2π, is the quantization of angular momentum.
Characteristic.

プランク定数（プランクていすう、プランクじょうすう、英語: Planck constant ）は、光子のもつエネルギーと振動数の比例関係をあらわす比例定数のことで、量子論を特徴付ける物理定数である。 量子力学の創始者の一人であるマックス・プランクにちなんで命名された。 Thanks for the welcome! We don't have here some sort of mass in some potential field, and the mass moves and has potential and kinetic energy. Our description of Planck-constant-over-2-pi includes its symbol, two metric (SI) equivalents, metric (SI) dimensions, other names, and a link to the units in its physical quantity (planck constants).

Last updated: January 17, 2011 swj January 17, 2011 swj The energy of an oscillator, as Planck defined, is quantized.It may be related to a harmonic oscillator, but it won't be simple to explain whose is the potential energy and the kinetic energy. Plancks constant can now be measured with very high precision. 3.156 × 10 7 s. Return to Physics 342 homepage.

However equally common (really, more common in any QM applications), is the reduced planck's constant #h/(2pi)#. Physicist noted that 2pi recurs with sufficient frequency (bad pun intended) that this factor is frequently absorbed into "h-bar."
