Chirality vs Handedness - Physics Stack Exchange

WebHelicity and chirality are not the same thing in the massless limit. They are unrelated. Helicity is an extrinsic physical property related to the alignment of spin and momentum; chirality is related to weak interactions. Chirality is more akin to electric charge or strong color charge than it is to momentum. WebNotes on visual chirality vs. geometric chirality. Here we make a few clarifying observations about visual chirality. First, while geometric chirality is a binary property of ob-jects, visual chirality can be described in terms of how much Equation 1 is violated, letting us discuss it as a continuous

WebNone of them actually. I had a conceptual question. If you cannot easily see the plane of symmetry when drawing it out, does not having a chiral center vs having a chiral center determine chirality vs achirality.
