Okay, so they have pictures in this book of a bunch of the atoms.
-
This is helium, which has seventy-two anu.
-
This is lithium with 127 anu.
-

and this is the wooden base it sits on.
-
Here's iron, 1008 anu.
-

-
calculated by quantum mechanics.
-
Now the question is, why would you believe me,
-
or believe a textbook, or believe a quantum mechanician,
