Quotes from the same author
Radio - and perhaps airplanes, and then of course, the atom bomb - was the preeminent technology of the first half of the 20th century. It was how the Third Reich controlled its citizens, spread lies, and disseminated fear.
Anthony Doerr
We all come into existence as a single cell, smaller than a speck of dust. Much smaller. Divide. Multiply. Add and subtract. Matter changes hands, atoms flow in and out, molecules pivot, proteins stitch together, mitochondria send out their oxidative dictates; we begin as a microscopic electrical swarm. The lungs the brain the heart. Forty weeks later, six trillion cells get crushed in the vise of our mother’s birth canal and we howl. Then the world starts in on us.
