"7 Cups of Tea, by Lu Tong (795 - 835 CE)
The first cup kisses away my thirst,
and my loneliness is quelled by the second.
The third gives insight worthy of ancient scrolls,
and the fourth exiles my troubles.
My body becomes lighter with the fifth,
and the sixth sends word from immortals.
But the seventh—oh the seventh cup—
if I drink you, a wind will hurry my wings
toward the sacred island."
"From an evolutionary perspective, the only reason for pain that makes sense to me is that it enables long-term protection," he says. Pain may provide an animal with an additional, and memorable, means of focusing on a source of harm that helps it avoid it in future. If an animal’s lifespan is not long enough to benefit from that – as is the case with most insects – then pain has no use. Similarly, some animals may simply be unable to avoid noxious stimuli in the first place. "Is a barnacle going to benefit from a bad experience?" says Elwood. "I doubt it."
"Scientists put bull sperm cells in a petri dish along with a couple dozen iron-titanium nanotubes. The tubes act like those woven fingertraps—sperm can swim into them but can’t back themselves out. Using magnets, scientists can then steer the swimmers in the direction of their choosing. It’s like a remote-control robot where the sperm start the engines and the researchers provide the navigation."
"And though the body and form of the book will continue to evolve, its heart and soul never will. Though the telescope might change, the cosmic truths it invites you to peer into remain eternal like the Universe."
