From the introduction:
It’s late, and you are alone in the lab. You’ve been working for hours chasing down a new theory, scouring the latest data for patterns, repeating test after test to get something conclusive. Your shoulders ache, your eyes fight to stay open, your back longs to lie flat. “Just one more hour,” you tell yourself, “then I give up for the night.” You take a sip of water, stretch your limbs, and refocus your mind on the task at hand.
Then you notice something out of the corner of your eye. At first you’re sure it’s nothing, just your mind playing tricks after weeks of sleep deprivation and overexertion. But then you see it again, and turn your full attention toward it.
Sure enough, it’s alive.
