Quotes by Science Writers

Only cells that had been transformed by a virus or a genetic mutation had the potential to become immortal.
Rebecca Skloot
All we know for sure is that if some astronomer turned a telescope to a far-off star cluster tonight and found incontrovertible evidence of life, even microbial scavengers, it would be the most important discovery ever—proof that human beings are not so special after all. Except that we exist, too, and can understand and make such discoveries.

Unlike modern pills, these hard antimony pills didn’t dissolve in the intestines, and the pills were considered so valuable that people rooted through fecal matter to retrieve and reuse them. Some lucky families even passed down laxatives from father to son. Perhaps for this reason, antimony found heavy work as a medicine, although it’s actually toxic. Mozart probably died from taking too much to combat a severe fever.
Sam Kean
In these days before antiseptics, doctors themselves also suffered high mortality rates. Florence Nightingale, a nurse during the Crimean War (1853-1856), watched one particularly inept surgeon cut both himself and, somehow, a bystander while blundering about during an amputation. Both men contracted an infection and died, as did the patient. Nightingale commented that it was the only surgery she'd ever seen with 300 percent mortality.

A so-called antimony war had been waged between French [Galenist] physicians and [alchemical, Paracelsian] iatrochemists since the beginning of the seventeenth century. What it lacked in bloodletting, this war made up for in bile.
Philip Ball
No matter who you were in sixteenth-century Europe, you could be sure of two things: you would be lucky to reach fifty years of age, and you could expect a life of discomfort and pain. Old age tires the body by thirty-five, Erasmus lamented, but half the population did not live beyond the age of twenty. There were doctors and there was medicine, but there does not seem to have been a great deal of healing. Anyone who could afford to seek a doctor's aid did so eagerly, but the doctor was as likely to maim or kill as to cure. His potions were usually noxious and sometimes fatal—but they could not have been as terrible and traumatic as the contemporary surgical methods. The surgeon and the Inquisitor differed only in their motivation: otherwise, their batteries of knives, saws, and tongs for slicing, piercing, burning, and amputating were barely distinguishable. Without any anesthetic other than strong liquor, an operation was as bad as the torments of hell.
Philip Ball
It was like bouncing tennis balls off a mystery piece of furniture and deducing, from the direction in which the balls ricocheted, whether it was a chair or a table or a Welsh dresser.
Marcus Chown
Heisenberg's uncertainty relation measures the amount by which the complementary descriptions of the electron, or other fundamental entities, overlap. Position is very much a particle property - particles can be located precisely. Waves, on the other hand, have no precise location, but they do have momentum. The more you know about the wave aspect of reality, the less you know about the particle, and vice versa. Experiments designed to detect particles always detect particles; experiments designed to detect waves always detect waves. No experiment shows the electron behaving like a wave and a particle at the same time.
John Gribbin
Yet they enjoy the high. In the surest sign that selenium actually makes them go mad, cattle grow addicted to locoweed despite its awful side effects and eat it to the exclusion of anything else. It’s animal meth.
Sam Kean
Also unlike a planet, an electron—if excited by heat or light—can leap from its low-energy shell to an empty, high-energy shell. The electron cannot stay in the high-energy state for long, so it soon crashes back down. But this isn’t a simple back-and-forth motion, because as it crashes, the electron jettisons energy by emitting light.

They also knew that there was a string of DNA at the end of each chromosome called a telomere, which shortened a tiny bit each time a cell divided, like time ticking off a clock. As normal cells go through life, their telomeres shorten with each division until they’re almost gone. Then they stop dividing and begin to die. This process correlates with the age of a person: the older we are, the shorter our telomeres, and the fewer times our cells have left to divide before they die. By the early nineties, a scientist at Yale had used HeLa to discover that human cancer cells contain an enzyme called telomerase that rebuilds their telomeres. The presence of telomerase meant cells could keep regenerating their telomeres indefinitely. This explained the mechanics of HeLa’s immortality: telomerase constantly rewound the ticking clock at the end of Henrietta’s chromosomes so they never grew old and never died.

... I succeeded at math, at least by the usual evaluation criteria: grades. Yet while I might have earned top marks in geometry and algebra, I was merely following memorized rules, plugging in numbers and dutifully crunching out answers by rote, with no real grasp of the significance of what I was doing or its usefulness in solving real-world problems. Worse, I knew the depth of my own ignorance, and I lived in fear that my lack of comprehension would be discovered and I would be exposed as an academic fraud -- psychologists call this "imposter syndrome".

As a result of its investigation, the NIH said that to qualify for funding, all proposals for research on human subjects had to be approved by review boards—independent bodies made up of professionals and laypeople of diverse races, classes, and backgrounds—to ensure that they met the NIH’s ethics requirements, including detailed informed consent. Scientists said medical research was doomed. In a letter to the editor of Science, one of them warned, “When we are prevented from attempting seemingly innocuous studies of cancer behavior in humans … we may mark 1966 as the year in which all medical progress ceased.

This hinted at something that no one had ever suspected -- that the brain tracks moving things more easily that still things. We have a built-in bias toward detecting action. Why? Because it's probably more critical for animals to spot moving things (predators, prey, falling trees) than static things, which can wait. In fact, our vision is so biased toward movement that we don't technically see stationary objects at all. To see something stationary, our brains have to scribble our eyes subtly over its surface. Experiments have even proven that if you artificially stabilize an image on the retina with a combination of special contact lenses and microelectronics, the image will vanish.
Sam Kean
When you do the math and examine how much energy is produced per atomic union, you find that fusing anything to iron’s twenty-six protons costs energy. That means post-ferric fusion* does an energy-hungry star no good. Iron is the final peal of a star’s natural life.

The waitress serving the wedding party was a short young blonde. She took their orders efficiently and delivered everyone’s food correctly. "If only she knew my story," Melora mused. then she thought again, "Better yet, maybe she’s in the middle of her own story." Who knew what things might have happened already on the island to this typical college-age waitress.
Marie Zhuikov
I will never listen to ocean waves or view a beautiful sunset in quite the same way again. That is perhaps the greatest gift one can gain by delving into calculus: It is a whole new way of looking at the world, accessible only through the realm of mathematics.
Jennifer Ouellette
For me, it's writing a book and telling people about this story.
Rebecca Skloot
Evolution has taught them that pointless harm will ultimately harm themselves.
Carl Zimmer
From Lankaster to Lorenz, scientists have gotten it wrong. Parasites are complex, highly adapted creatures that are at the heart of the story of life. If there hadn't been such high walls dividing scientists who study life - the zoologists, the immunologists, the mathematical biologists, the ecologists - parasites might have been recognized sooner as not disgusting, or at least not merely disgusting. If parasites were so feeble, so lazy, how was it that they could manage to live inside every free-living species and infect billions of people? How could they change with time so that medicines that could once treat them became useless? How could parasites defy vaccines, which could corral brutal killers like smallpox and polio?
Carl Zimmer
I have lost tolerance for things without meaning. There is no time for them. Does that make sense? - Sara Seager
Lee Billings
Today alpha equals 1/137.0359 or so. Regardless, its value makes the periodic table possible. It allows atoms to exist and also allows them to react with sufficient vigor to form compounds, since electrons neither roam too freely from their nuclei nor cling too closely. This just-right balance has led many scientists to conclude that the universe couldn’t have hit upon its fine structure constant by accident.
Sam Kean
All the elements other than hydrogen and helium make up just 0.04 percent of the universe. Seen from this perspective, the periodic system appears to be rather insignificant. But the fact remains that we live on the earth… where the relative abundance of elements is quite different.

I am constantly amazed by how much stranger science is than science fiction
Marcus Chown
Germans at the time believed, a little oddly, that dyes killed germs by turning the germs’ vital organs the wrong color.
Sam Kean
For his part, Mendeleev scanned Lecoq de Boisbaudran’s data on gallium and told the experimentalist, with no justification, that he must have measured something wrong, because the density and weight of gallium differed from Mendeleev’s predictions. This betrays a flabbergasting amount of gall, but as science philosopher-historian Eric Scerri put it, Mendeleev always “was willing to bend nature to fit his grand philosophical scheme.” The only difference between Mendeleev and crackpottery is that Mendeleev was right: Lecoq de Boisbaudran soon retracted his data and published results that corroborated Mendeleev’s predictions.

Earlier maps had underestimated the distances to other continents and exaggerated the outlines of individual nations. Now global dimensions could be set, with authority, by the celestial spheres. Indeed, King Louis XIV of France, confronted with a revised map of his domain based on accurate longitude measurements, reportedly complained that he was losing more territory to his astronomers than to his enemies.

Stupid entropy ruins everything.
Jennifer Ouellette
It is only rather recently that science has begun to make peace with its magical roots. Until a few decades ago, it was common for histories of science either to commence decorously with Copernicus's heliocentric theory or to laud the rationalism of Aristotelian antiquity and then to leap across the Middle Ages as an age of ignorance and superstition. One could, with care and diligence, find occasional things to praise in the works of Avicenna, William of Ockham, Albertus Magnus, and Roger Bacon, but these sparse gems had to be thoroughly dusted down and scraped clean of unsightly accretions before being inserted into the corners of a frame fashioned in a much later period.
Philip Ball
Peasants brought up on a tradition of superstitious magic could hardly be expected to distinguish between such ostensibly Christian rituals and the mumbled incantations of the local wizard. And so, to the discomfort of the priests, many came to regard elements of Christian devotion as simple magical spells. The Latin Mass was, after all, incomprehensible to the common people, so it already had the aspect of an occult formula. It came to be seen, like magic, as an essentially mechanical rite through which absolution was achieved by observing the correct procedures. In that case, there was no real need for faith.
