12:15 *due* to large M_alpha... 17:55 "...a possible way to write an *ansatz* would..."

[@queeeeeee]

12:15 this view to large M_alpha?

i am confused what is skeleton is it a whole molecule?

[@Vampofthedon]

The skeleton of a molecule is the carbon backbone of the molecule from which your functional groups can attach to.

[@nimehg5734]

skeleton of fixed nucleus.

[@brainstormedperson132]

You assume that the nuclei dont move and you know their positions and you call those fixed nuclei on their known positions the sceleton

[@Angelito082]

The skeleton is the structure, that you consider in molecular mechanics

[@brendawilliams8062]

I can’t follow this. So back to my geometry

Electron, proton, neutron, ... make up this universe. Their pronunciation should be distinct. This is better accomplished by using the US pronunciation rule for the -ON end, /ɑːn/ or /än/ instead of /ɒn/ or /ən/ which make those particle names sound insignificant and actually a bit weird. For instance, for Electron, use /iˈlek.trɑːn/ or /əˈlekˌträn/ instead of /iˈlek.trɒn/, or /əˈlekˌtrən/. Suggest the particle physics community adopt this rule.
