I just saw that estimate for atoms in an average human body is on the order of 10^27. I didn’t expect that the whole body is 100,000x atoms compared to the eye.

I just saw that estimate for atoms in an average human body is on the order of 10^27. I didn’t expect that the whole body is 100,000x atoms compared to the eye. By weight (68kg/28g) the body is only about 2500x the size of an eye.
