"“To see a world in a grain of sand”, the opening sentence of the poem by
William Blake, is an oft-used phrase that also captures some of what geologists
do.

We observe the composition of mineral grains, smaller than the width of a human
hair. Then, we extrapolate the chemical processes they suggest to ponder the
construction of our planet itself.

Now, we’ve taken that minute attention to new heights, connecting tiny grains
to Earth’s place in the galactic environment."
