How many atoms in human body?
- Total Earth biomass 550 GT carbon 5.5 x 1e2 x 1e9 x 1e6 (tonnes per gram) = 5.5e17 grams
- carbon is 12 amu and 12% of the atoms in human body
- Avogadro's number 6e23, hence one gram of human carbon is 5e22 atoms
- Associated with (100/12)*5e22 ≈ 4e21 total atoms per gram of human carbon
Fermi estimate: Total Earth biomass 5.5e17 * 4e21 atoms = 2e39 biomass atoms if humans representative
- There are 1e22 to 1e24 stars in the universe
- Thousands of asteroids and trillions of comets and icy bodies orbit the Sun
- Perhaps 3e12 comets per star times 1e24 stars is 6e36 icy bodies in the universe, not counting unbound bodies
- that's a LOT of physics
- Both biology and physics are complicated ... or simple, if one is a simpleton
