Handedness vs. Helicity
editHelicity is something else from handedness, look it up, for example in Perkins, and fix it. I have no time now, but this is wrong imho. —Preceding unsigned comment added by 217.121.85.171 (talk) 11:15, 30 December 2007 (UTC)
- Helicity is related to handedness. I refer you to Krane - introduction to nuclear physics. I can't remember the page number - look it up in the index. Georgeryall (talk) 00:26, 26 November 2009 (UTC)
- Helicity is a measure of handedness in the direction of propogation 86.136.222.154 (talk) 19:24, 16 January 2011 (UTC)
- Yes, that's right. 67.198.37.16 (talk) 19:40, 30 November 2020 (UTC)
What is helicity?
editThis article needs improvement. I didn't understand the lead or the introduction, and I graduated from college with a physics major. Projection of spin onto momentum? Spin is a QM phenomenon, so I don't see how it "projects" onto other properties, such as position or momentum or energy. Can a diagram be added to show what it means? I know what a helix is: circular curve or motion that is stretched out along its axis. But is this article talking about angular momentum stretched out along its axis? Or is it talking about EM waves perhaps? I can't tell exactly what the subject matter is without a clear explanation and perhaps a diagram or two. David Spector (talk) 22:49, 29 July 2023 (UTC)
