Ten to the negative six

Earlier today, while I was watching TV, I saw a man speaking to an audience about various things. One of the topics he touched upon was the “microscopic dot” which contains all the information necessary for one’s journey in the physical world. It was clear that he was referencing the minute collection of cells soon created soon after conception. He then proceeded to describe just how small this “microscopic dot” was: “…you can’t even see it with a microscope….”
Hmmm…microscope…microscopic…maybe these words are related.
Do people even know what the words they use mean?
