What sand really looks like—grains of sand, magnified
One thing I have learned in a long life: that all our science, measured against reality, is primitive and childlike — and yet it is the most precious thing we have.
Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
Live in each season as it passes; breathe the air, drink the drink, taste the fruit, and resign yourself to the influence of the earth.
— Henry David Thoreau, Walden (via currentsinbiology)
