1 " On Friday the 13th of April 2029, an asteroid large enough to fill the Rose Bowl as though it were an egg cup, will fly so close to Earth, that it will dip below the altitude of our communication satellites. We did not name this asteroid Bambi. Instead, it's named Apophis, after the Egyptian god of darkness and death. If the trajectory of Apophis at close approach passes within a narrow range of altitudes called the 'keyhole,' the precise influence of Earth's gravity on its orbit will guarantee that seven years later in 2036, on its next time around, the asteroid will hit Earth directly, slamming in the Pacific Ocean between California and Hawaii. The tsunami it creates will wipe out the entire west coast of North America, bury Hawaii, and devastate all the land masses of the Pacific Rim. If Apophis misses the keyhole in 2029, then, of course, we have nothing to worry about in 2036. "

2 " I was moving in a narrow range between busy distractedness and a pervasive sadness whose granules seemed to enter each cell, weighing it down... I ghosted between islands of anxiety... a fatigue that dulled my zest, decanted it. Sorrow felt like a marble coat I couldn’t shed. "

3 " Life is fragile: it thrives only in a narrow range of temperatures between freezing and boiling. How lucky that our planet is just the right distance from the sun: a little farther, and the death of the perpetual Antarctic winter - or worse - would prevail; a little closer, and the surface would truly fry anything that touched it.
