Moments snap together like magnets, forging a chain of shackles. Why?

There’s a famous play, Equus, about a troubled boy with a blinding love of horses. The boy sees a psychiatrist named Martin Dysart, who tries to understand him by trying to understand his love. Dysart is confounded by it:

A child is born into a world of phenomena all equal in their power to enslave. It sniffs—it sucks—it strokes its eyes over the whole uncountable range. Suddenly one strikes. Why? Moments snap together like magnets, forging a chain of shackles. Why? I can trace them. I can even, with time, pull them apart again. But why at the start they were ever magnetized at all—just those particular moments of experience and no others—I don’t know. 

I can trace my love, too. Why stars instead of horses, or boys, or hockey? I don’t know. I don’t know. Maybe it’s because the stars are the antithesis of darkness, of abusive stepfathers and imperiled little sisters. Stars are light. Stars are possibility. They are the places where science and magic meet, windows to worlds greater than my own. Stars gave me the hope that I might one day find the right answers.

But there’s more to my love than that. When I think of the stars I feel an almost physical pull. I don’t just want to look at them. I want to know them, every last one of them, a star for every grain of sand on Earth. I want to bask in the hundreds of millions of suns that shine in the thousands of billions of skies in our galaxy alone. Stars represent more than possibility to me; they are probability. On Earth the odds could seem stacked against me—but where you are changes everything. Each star was, and still is, another chance for me to find myself somewhere else. Somewhere new.

duck-cold-winter

A small child next to us looked down at her snow-covered boots, then pointed to a duck that stood on the ice on the bank and asked her mother an extremely good question: “Why don’t his feet get cold?”…

It’s this: The bigger the temperature difference between two objects when they touch, the faster heat will flow from one to the other. Another way of putting that is to say that the more similar the temperatures of the two objects are, the more slowly heat will flow from one to the other. And that’s what really helps the ducks. As all that frantic paddling was going on, warm blood was flowing down the arteries of each duck’s legs. But those arteries were right next to the veins carrying blood back from the feet. The blood in the veins was cool. So the molecules in the warm blood jostled the blood vessel walls, which then jostled the cooler blood. The warm blood going to the feet got a bit cooler, and the blood going back into the body was warmed up a bit. Slightly farther down the duck’s leg, the arteries and the veins are both cooler overall, but the arteries are still warmer. So heat flows across from the arteries to the veins. All the way down the duck’s legs, heat that came from the duck’s body is being transferred to the blood that’s going back the other way, without going near the duck’s feet. But the blood itself goes all the way around. By the time the duck’s blood reaches its webbed feet, it’s pretty much the same temperature as the water. Because its feet aren’t much hotter than the water, they lose very little heat. And then as the blood travels back up toward the middle of the duck, it gets heated up by the blood coming down. This is called a countercurrent heat exchanger, and it’s a fantastically ingenious way of avoiding heat loss. If the duck can make sure that the heat doesn’t get to its feet, it has almost eliminated the possibility of losing energy that way.

So ducks can happily stand on the ice precisely because their feet are cold. And they don’t care.

comet-45p-honda-mrkos-pajdusakova

Comet 45P/Honda–Mrkos–Pajdušáková was first discovered 13 orbits ago in 1948 and has returned to the inner Solar System. It is physically ancient. It spends most of its time near the orbit of Jupiter and last neared the Sun in 2011. Over the past few months, Comet 45P’s new sunward plummet has brightened it considerably. The comet is currently visible with binoculars over the western horizon just after sunset, not far from the much brighter planet Venus. Comet 45P was captured last week sporting a long ion tailwith impressive structure. It will pass relatively close to the Earth early next month.”

It is the sense of mystery that […] drives the true scientist. […]

If he has not experienced, at least a few times in his life, this cold shudder down his spine, this confrontation with an immense, invisible face whose breath moves him to tears, he is not a scientist.

The blacker the night, the brighter the light.

Fashionable descriptions of the inevitable triumph of machine intelligence (over man) contain many critical biases and assumptions that could derail them from turning into reality. […]

Our brains use energy at a rate of about 20 watts. If you wanted to upload yourself intact into a machine using current computing technology, you’d need a power supply roughly the same as that generated by the Three Gorges Dam hydroelectric plant in China, the biggest in the world. To take our species, all 7.3 billion living minds, to machine form would require an energy flow of at least 140,000 petawatts. That’s about 800 times the total solar power hitting the top of Earth’s atmosphere. Clearly human transcendence might be a way off.

inability to grasp the most central aspects of human life

martin-stranka

It is to say, though, that if you believe that science provides no basis for God, then you are almost obligated to conclude that science provides no basis for meaning and, therefore, life itself doesn’t have any. In other words, existential claims have no weight; all knowledge is scientific knowledge. Yet the paradox is that scientific methodology is the product of human hands and thus cannot reach some permanent truth. We build scientific theories to organize and manipulate the world, to reduce phenomena into manageable units. Science is based on reproducibility and manufactured objectivity. As strong as that makes its ability to generate claims about matter and energy, it also makes scientific knowledge inapplicable to the existential, visceral nature of human life, which is unique and subjective and unpredictable. Science may provide the most useful way to organize empirical, reproducible data, but its power to do so is predicated on its inability to grasp the most central aspects of human life: hope, fear, love, hate, beauty, envy, honor, weakness, striving, suffering, virtue.

NY Times Letter to the Editor:

The Chirp Heard Across the Universe” (editorial, Feb. 16), about the recent discovery of the gravitational waves that were predicted by Einstein a century ago, asks, “Does science, or knowledge, really need a justification?”

The answer, of course, is no. But in a culture that has become saturated with the idea that only commercial value matters, we’ve become afraid of expressing an impulse as natural and basic as this.

Much like literature, music, philosophy and art, enjoyment of the natural sciences — and of nature itself — has intrinsic value. No further justification is required. Curiosity, wonder and beauty are enough.

And, it was “game over”

Eric-Metaxas

[…]

Mr. (Eric) Metaxas pushes back against what he calls the “lie that faith and science are somehow opposed to each other.” He thinks the two work in tandem. As he wrote last year in these pages: “There are more than 200 known parameters necessary for a planet to support life—every single one of which must be perfectly met, or the whole thing falls apart.” In sum: “Can every one of those many parameters have been perfect by accident?”

This resonates with people. “They say: ‘You know, it didn’t make sense to me that the universe made no sense.’ ” In his book about the miraculous, Mr. Metaxas cites the Christian scholar C.S. Lewis, who wrote in his 1952 book “Mere Christianity”: “If the whole universe has no meaning, we should never have found out that it has no meaning: just as, if there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be without meaning.” […]

While he “floundered,” he was influenced by a good friend who was a Christian. Mr. Metaxas’ initial attitude was: “Don’t come too close. That’s all that weird stuff I’ve been trained to avoid. On the other hand, tell me just a little bit more.” The friend gave him “The Cost of Discipleship,” by Dietrich Bonhoeffer, the German Lutheran pastor from a prominent family who stood in solidarity with the Jews in World War II, publicly denouncing the Nazis at his peril. At age 39 Bonhoeffer was murdered by Hitler’s henchmen two weeks before the Americans liberated Flossenbürg.

This story laid the groundwork for Mr. Metaxas’ “dramatic” conversion experience, which he says happened overnight, in a dream. It was “game over.” He said he knew he believed in Christianity and his only question was: “How do I reconcile my life to this?” […] [Read more…]

Come up heads 10 quintillion times in a row. Really?

I so was fascinated by this opinion piece in yesterday’s paper that I have shared all but a few sentences from the article by Eric Metaxas, Science Increasingly Makes the Case for God:

In 1966 Time magazine ran a cover story asking: Is God Dead? Many have accepted the cultural narrative that he’s obsolete—that as science progresses, there is less need for a “God” to explain the universe. Yet it turns out that the rumors of God’s death were premature. More amazing is that the relatively recent case for his existence comes from a surprising place—science itself.

Here’s the story: The same year Time featured the now-famous headline, the astronomer Carl Sagan announced that there were two important criteria for a planet to support life: The right kind of star, and a planet the right distance from that star. Given the roughly octillion—1 followed by 24 zeros—planets in the universe, there should have been about septillion—1 followed by 21 zeros—planets capable of supporting life.

With such spectacular odds, the Search for Extraterrestrial Intelligence, a large, expensive collection of private and publicly funded projects launched in the 1960s, was sure to turn up something soon…As of 2014, researches have discovered precisely bubkis—0 followed by nothing.

What happened? As our knowledge of the universe increased, it became clear that there were far more factors necessary for life than Sagan supposed….Today there are more than 200 known parameters necessary for a planet to support life—every single one of which must be perfectly met, or the whole thing falls apart. Without a massive planet like Jupiter nearby, whose gravity will draw away asteroids, a thousand times as many would hit Earth’s surface. The odds against life in the universe are simply astonishing.

It’s dark. Still. Quiet.
We’re both calm.
I look up.

Something bigger, much bigger here.


In quietness,
the sound of eternity
can at times be heard—
the stars somehow closer and
a sense of the earth’s moving.

ants

Put a few thousand ants on to a pile of dirt and in a week they will have built a labyrinthine city inside it. If a flood hits the colony they can mesh their own bodies together into a raft the size of a dinner plate and ship themselves to safety. All done without blueprint or leader. How? Not because ants are smart. But because they know to follow simple rules. Three, to be exact. Read more here.

This is a bit of an epic fail

planets-earth-girl-bubbles

Steve Layman’s shares “7 Questions About the Universe That No One Has Answered“:

…There’s also so much mess after 4.5 billion years of geophysics that some of our best information about the planet’s origins come from meteorites and the cratering of other worlds — outsourced. Speaking of other worlds, we’re not even sure we understand where the Moon came from, maybe it was a giant impact, maybe not. For an allegedly clever species on a small rocky planet this is a bit of an epic fail…

There’s an awful lot we don’t know (far more than just the examples here). But the point is not to get despondent, because this ignorance is a beautiful thing. It’s what ultimately drives science, and it’s what makes the universe truly awe-inspiring. After the hundreds of thousands of years that Homo sapienshas loped around, the cosmos can still elude our fidgety, inquisitive minds, easily outracing our considerable imaginations. How wonderful.

It seems too good to be true

galaxy-life-stars

“Some things occur just by chance. Mark Twain was born on the day that Halley’s comet appeared in 1835 and died on the day it reappeared in 1910. There is a temptation to linger on a story like that, to wonder if there might be a deeper order behind a life so poetically bracketed. For most of us, the temptation doesn’t last long. We are content to remind ourselves that the vast majority of lives are not so celestially attuned, and go about our business in the world. But some coincidences are more troubling, especially if they implicate larger swathes of phenomena, or the entirety of the known universe. During the past several decades, physics has uncovered basic features of the cosmos that seem, upon first glance, like lucky accidents. Theories now suggest that the most general structural elements of the universe — the stars and planets, and the galaxies that contain them — are the products of finely calibrated laws and conditions that seem too good to be true. What if our most fundamental questions, our late-at-night-wonderings about why we are here, have no more satisfying answer than an exasperated shrug and a meekly muttered ‘Things just seem to have turned out that way’?

It can be unsettling to contemplate the unlikely nature of your own existence, to work backward causally and discover the chain of blind luck that landed you in front of your computer screen, or your mobile, or wherever it is that you are reading these words. For you to exist at all, your parents had to meet, and that alone involved quite a lot of chance and coincidence. If your mother hadn’t decided to take that calculus class, or if her parents had decided to live in another town, then perhaps your parents never would have encountered one another. But that is only the tiniest tip of the iceberg. Even if your parents made a deliberate decision to have a child, the odds of your particular sperm finding your particular egg are one in several billion. The same goes for both your parents, who had to exist in order for you to exist, and so already, after just two generations, we are up to one chance in 1027. Carrying on in this way, your chance of existing, given the general state of the universe even a few centuries ago, was almost infinitesimally small. You and I and every other human being are the products of chance, and came into existence against very long odds…”

These are mind blowing large numbers

Parmitano-photo-of-earth

…Just how many planets are there?…There could be about 23 billion stars in our Milky Way galaxy, each harbouring Earth-sized planets with life-friendly temperatures on their surfaces. Twenty-three billion, give or take a few…Some studies produce numbers of Earth-sized planets closer to 17 billion…Others suggest a figure as low as 6 billion or so, but these are just the planets close to Earth in size. If we extend our reach to slightly larger worlds, the places now known as ‘super-Earths’, we’re back into the tens of billions. No matter how you slice the cosmic cake, you end up with a vast wedge of planets that we’d be happy to go and study, perhaps even land on and cautiously tiptoe about. These are mind-blowingly huge numbers…

So, given the enormity of the number of planets in the galaxy, the question Caleb Scharf tries to answer in his essay is: Are We Alone?

Vibrant Produce

“The risk of hospitalization or death from heart disease is 32% lower in vegetarians than people who eat meat and fish, according to a new study from the University of Oxford.

Heart disease is the single largest cause of death in developed countries…The new findings, published in the American Journal of Clinical Nutrition, suggest that a vegetarian diet could significantly reduce people’s risk of heart disease…This is the largest study ever conducted in the UK comparing rates of heart disease between vegetarians and non-vegetarians. The analysis looked at almost 45,000 volunteers from England and Scotland…of whom 34% were vegetarian. Such a significant representation of vegetarians is rare in studies of this type, and allowed researchers to make more precise estimates of the relative risks between the two groups.”

You spring from an unbroken line of winners…

 

“Every living thing is, from the cosmic perspective, incredibly lucky simply to be alive. Most, 90 percent and more, of all the organisms that have ever lived have died without viable offspring, but not a single one of your ancestors, going back to the dawn of life on Earth, suffered that normal misfortune. You spring from an unbroken line of winners going back millions of generations, and those winners were, in every generation, the luckiest of the lucky, one out of a thousand or even a million. So however unlucky you may be on some occasion today, your presence on the planet testifies to the role luck has played in your past.”

~ Philosopher and cognitive scientist Dan Dennett
