It&#x27;s not just about the ideas -- it&#x27;s about how they are explained and with what rigor.<p>The same way that 19th chemistry didn&#x27;t &quot;got where Democritus was&quot; when he formulated his atomic theory -- it came to the same concept, yes, but what for him was just an idea put out there, for them it was a solid theory, with experiments, deductions made of it, etc.
