It&amp;#x27;s quite obvious in retrospect to acknowledge that quantum mechanics is the physics of chemistry, and I don&amp;#x27;t know why I didn&amp;#x27;t see that before. It certainly helps to view a lot of things in a new light.</text><parent_chain><item><author>jdewerd</author><text>&amp;gt; there may be quantum effects involved&lt;p&gt;Quantum Mechanics is why atoms and molecules exist and form bonds.
