“Nature
has put itself the problem of how to catch in flight light streaming to
the Earth and to store the most elusive of all powers in rigid form.
The plants take in one form of power, light; and produce another power,
chemical difference.”
— Julius Robert Mayer
“The vital chemical process was the ultimate source of energy
for a living organism.”
— Julius Robert Mayer
“... I hear words by the poet Rilke: ‘... if you set this
brain of mine on fire, then on my blood I yet will carry
you.’”
