Methuselah's Zoo

what nature can teach us about living longer, healthier lives

  • 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
