Quotes by Sam Kean

In fact, his travelogues spend amazingly little time discussing his blindness. Only one passage stands out for its frank discussion of his handicap and how it changed his worldview. In it, Holman was reminiscing about a few rendezvous from his past. Disarmingly, he admitted that he had no idea what his paramours looked like, or even whether they were homely. Moreover, he didn't care: by abandoning the standards of the sighted world, he argues, he could tap into a more divine and more authentic beauty. Hearing a woman's voice and feeling her caresses -- and then filling in what was missing with his own fancy -- gave him more pleasure than the mere sight of a women ever had, he said, a pleasure beyond reality. Are there any who imagine, Holman asked, that my loss of eyesight must necessarily deny me the enjoyment of such contemplation? How much more do I pity the mental darkness which could give rise to such an error.

Think of the most fussy science teacher you ever had. The one who docked your grade if the sixth decimal place in your answer was rounded incorrectly; who tucked in his periodic table T-shirt, corrected every student who said weight when he or she meant mass, and made everyone, including himself, wear goggles even while mixing sugar water. Now try to imagine someone whom your teacher would hate for being anal-retentive. That is the kind of person who works for a bureau of standards and measurement.

Never underestimate spite as a motivator for genius.

After about 1940, scientists generally stopped looking for elements in nature. Instead, they had to create them by smashing smaller atoms together.

People adored Element 13's color and luster, which reminded them of the sparkle of gold and silver - a brand-new precious metal. In fact, aluminum became more precious than gold and silver in the 19th century because it was harder to obtain.

Animal vision - including human vision - is so biased toward movement that we don't technically see stationary objects at all.

Whereas recessive traits require two bad copies of a gene to become noticeable, a dominant trait expresses itself no matter what the other copy does. A benign example of dominance: If you inherit one gene for sticky wet earwax and one gene for dry earwax, the sticky earwax gene wins out every time.

The amygdala is one of those brain structures that a lot of people know a little bit about, and there's a definite tendency to conflate the amygdala and the fear response itself - as if the amygdala, and the amygdala alone, 'causes' fear.

Despite what you might guess, when monitoring your breathing, your body doesn't care whether you're inhaling enough oxygen. It cares only whether you're expelling enough carbon dioxide - that's the gas that sets off the panic button when you're suffocating.

Brain surgery couldn't happen without the patient's own active voice to guide the work. The patient is part of the surgical team here, perhaps the most important part, and above all, that's what makes neurosurgery different.

Things look especially bleak for common killers such as diabetes and heart disease. Those ailments clearly have a genetic component. But when scientists survey genes looking for which mutations patients have in common, they come up empty.

Every glass thermometer has subtle variations in the size and shape of the bulb at the bottom and the capillary tube inside, as well as variations in the width of gradations on the side. The compounded effect of these uncertainties is that each thermometer reads temperature slightly differently.

Most people who have encountered mercury have done so after breaking a mercury thermometer. And many of us who saw the liquid balls of mercury scatter across a floor or countertop considered the element the most beautiful on the periodic table.

Scientists have continued to tinker with different elements and have learned new ways to store and deliver energy.

Carbon's eastern neighbor on the table, nitrogen, dresses up diamonds in pinks, yellows, oranges, and brownish tints known romantically as 'champagne.'

As a child in the early 1980s, I tended to talk with things in my mouth - food, dentist's tubes, balloons that would fly away, whatever - and if no one else was around, I'd talk anyway.

Atoms consist of a positive nucleus and negative electrons flying around outside it. Electrons closest to the nucleus feel a strong negative-on-positive tug, and the bigger atoms get, the bigger the tug. In really big atoms, electrons whip around at speeds close to the speed of light.
