 * I agree. Another point: What is "A molecular system in the real world is unlikely to be present in vacuum." supposed to mean? I would clarify it if I just had an idea what the editor wanted to say here. Seattle Jörg (talk) 08:33, 4 April 2013 (UTC)


 * Disagree. Langevin dynamics is more about computational simulation. "A molecular system in the real world is unlikely to be present in vacuum." is also talking about simulation where larger molecules are usually presented without solvent molecules. Wayoflights (talk) 03:00, 18 June 2014 (UTC)


 * Comment: 15 years on, this article is still a stub. Whoever it is in chemistry that uses this, they are not active on WP. 67.198.37.16 (talk) 23:44, 23 May 2024 (UTC)

gamma is the friction coefficient
this seems to be inconsistent with the article which claims gamma to be the viscosity--129.69.120.59 (talk) 14:38, 13 September 2019 (UTC)

Erroneous equation
In the equation
 * $$M\ddot{X} = - \nabla U(X) - \gamma M \dot{X} + \sqrt{2 M \gamma k_B T} R(t)\,,$$

the left side is mass * acceleration (force), but the right side is confused. Where does the factor of M come from in
 * $$\gamma M \dot{X}$$ ??

The units are wrong. — Preceding unsigned comment added by 2A00:23C7:598B:6F00:94E6:CED8:4B11:FFC2 (talk) 20:59, 16 May 2022 (UTC)
