I still don&#x27;t understand why snowflakes are symmetrical. There is symmetry across 3 &quot;planes of reflection.&quot; What is the mechanism that transmits information from one side of each plane of reflection to the opposite side?<p>Pop science explanations never explain this:<p><a href="http:&#x2F;&#x2F;www.scientificamerican.com&#x2F;article&#x2F;why-are-snowflakes-symmet&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.scientificamerican.com&#x2F;article&#x2F;why-are-snowflakes...</a><p>By analogy, one could say that Courier New zeros &quot;arrange themselves in predetermined spaces and in a specific arrangement.&quot; But this gives us any number of patterns across a line of symmetry, including a few non-symmetrical ones.<p><pre><code>    00000

So how does the communication happen? (I realize the communication is happening from the inside going out, with additional information being provided over time by the environment.)
