Why 1 Second Is 1 Second

Nathaniel Scharping in Discover Magazine:

Shutterstock_768685723Just what is a second, exactly? The question has been open to interpretation ever since the first long-case grandfather clocks began marking off seconds in the mid-17th century and introduced the concept to the world at large. The answer, simply, is that a second is 1/60th of a minute, or 1/3600th of an hour. But that’s just pushing the question down the road a bit. After all, what’s an hour? That answer is related to the best means of time-keeping ancient civilizations had — the movement of the Earth through the heavens. The amount of time it takes for the Earth to turn once about its axis, or for it to rotate once about the sun, is fairly stable, and for much of human history, it sufficed as a way of marking the passage of time. Days, hours, minutes — they’re all just derivatives of planetary motion.

Not Enough Time

Today, however, when computers perform operations at the rate of 4 billion cycles per second, we need a better measure. The rotation of Earth, and its orbit, change slightly over time. Earth’s rotation, for example, is slowing slightly. So measuring a second based on rotation would mean that a second would get slowly longer over time. Ultimately, we couldn’t compare the second of today to the second of yesterday. So, to pin down a truly timeless measure of a second, scientists in the 1950s devised a better clock, one based not on astronomical processes but on the movement of fundamental bits of matter — atoms — whose subtle vibrations are, for all intents and purposes, locked in for eternity. Today, one second is defined as “9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom”.

That’s a mouthful.

Will the Internet Destroy Us All?

Sarah LaBrie in The Millions:

MindWhen I was in graduate school, a professor introduced me to a documentary called The Century of the Self. Directed by BBC journalist Adam Curtis, it follows the rise of modern public relations, whose Austrian inventor, Edward Bernays, exploited Americans’ innate self-centeredness to sell us on everything from psychoanalysis to cigarettes. It’s an eye-opening piece of work, and one I used to rewatch once or twice a year. Last time I did though, it occurred to me that it might not be all that relevant. Because we aren’t living in the century of the self at all anymore, but the century of the crowd.

It would be easy, I guess, to argue that the self is still ascendant since social media gives people more ways to think about themselves than ever. But a hashtag can’t go viral with just one user, nobody cares about an Instagram photo no one likes, and does a YouTube video that doesn’t get watched even exist? Even as users do the self-focused work of updating LinkedIn profiles and posting on Twitter and Facebook, they do it in the service of belonging, at the back of everyone’s minds, an ever-present audience whose attention they need if their efforts aren’t to be wasted.

In his new book World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that this shift from individual to collective thinking is nowhere more evident than in the way we create and consume media on the Internet. Because tech companies like Facebook and Google make money off the sale of our personal data to advertisers, they depend on the attention of the masses to survive. And because their algorithms shape much of what we see online, it’s to their benefit to coerce us into thinking of ourselves not as individuals but as members of groups. “The big tech companies,” Foer writes, “Propel us to join the crowd—they provide us with the trending topics and their algorithms suggest that we read the same articles, tweets, and posts as the rest of the world.” Foer started his journalism career in the late ’90s as a writer for Slate when it was still owned by Microsoft. He edited The New Republic twice, from 2006 to 2010 and later, in 2012, after it was purchased by millennial billionaire and Facebook co-founder Chris Hughes. The year Foer first joined TNR, only college students could have Facebook accounts, the iPhone hadn’t yet been released, and the Internet still represented an opportunity for democratization, where a small website could attract a self-selecting group of readers simply by producing well-written articles about interesting things.

Today, there are two billion people on Facebook, which is also where most people get their news.

Sunday Poem

Every Morning After Killing Thousands of Angles
—excerpt

1

I read a boy's poem called
" Every Morning After Killing Thousands of Angles"
I forget the poem, but the title won't leave me
I drink some coffee
read a paper read by millions
all the misery
all the destruction in the world
herded into headlines and catch phrases
the only part I trust
is the financial page
a completely blank space governed
by the mechanics of capital and pure speculation

2

That boy's mornings
and my mornings—
how are they different?

But the boy can see the angels' faces

What’s So Dangerous About Psychology Professor Jordan Peterson?

Tom Bartlett in the Chronicle of Higher Education:

Photo_85360_landscape_850x566Soon the man himself will arrive and deliver an often dazzling, sometimes puzzling, rarely dull two-hour lecture on the symbolic and psychological underpinnings of the book of Genesis. Afterward he will field knotty questions from the audience on whether originality is really possible, the tension between honor and happiness, and the evolutionary upside of solitude. These questions seem designed to be difficult, as if the audience were engaged in a giant game of Stump the Guru. It’s during such sessions that Peterson is at his improvisational best, sprinkling in ideas from philosophy, fiction, religion, neuroscience, and a disturbing dream his 5-year-old nephew had one time. It’s a hearty intellectual stew ladled up by an intense 55-year-old psychology professor who gives the impression that he’s on the cusp of unraveling the deep secrets of human behavior — and maybe the mystery of God, too, while he’s at it.

You’d never guess from the reverential atmosphere in the 500-seat theater just how polarizing Peterson has become over the past year. Days before, fliers were tacked up around his neighborhood warning the community about the dangerous scholar in their midst, accusing him of "campaigning against the human rights" of minorities and associating with the alt-right. There have been several calls for his ouster from the University of Toronto — where he’s tenured — including a recent open letter to the dean of the faculty of arts and science signed by hundreds, including many of his fellow professors. Friends refuse to comment on him lest they be associated with his image. Critics hesitate, too, for fear that his supporters will unleash their online wrath. A graduate student at another Canadian university was reprimanded for showing a short video clip of Peterson to a group of undergraduates. One of the professors taking her to task likened Peterson to Hitler.

Philip K. Dick and the Fake Humans

Henry Farrell in The Boston Review:

Philipkdick2This is not the dystopia we were promised. We are not learning to love Big Brother, who lives, if he lives at all, on a cluster of server farms, cooled by environmentally friendly technologies. Nor have we been lulled by Soma and subliminal brain programming into a hazy acquiescence to pervasive social hierarchies.

…Standard utopias and standard dystopias are each perfect after their own particular fashion. We live somewhere queasier—a world in which technology is developing in ways that make it increasingly hard to distinguish human beings from artificial things. The world that the Internet and social media have created is less a system than an ecology, a proliferation of unexpected niches, and entities created and adapted to exploit them in deceptive ways. Vast commercial architectures are being colonized by quasi-autonomous parasites. Scammers have built algorithms to write fake books from scratch to sell on Amazon, compiling and modifying text from other books and online sources such as Wikipedia, to fool buyers or to take advantage of loopholes in Amazon’s compensation structure. Much of the world’s financial system is made out of bots—automated systems designed to continually probe markets for fleeting arbitrage opportunities. Less sophisticated programs plague online commerce systems such as eBay and Amazon, occasionally with extraordinary consequences, as when two warring bots bid the price of a biology book up to $23,698,655.93 (plus $3.99 shipping).

In other words, we live in Philip K. Dick’s future, not George Orwell’s or Aldous Huxley’s. Dick was no better a prophet of technology than any science fiction writer, and was arguably worse than most. His imagined worlds jam together odd bits of fifties’ and sixties’ California with rocket ships, drugs, and social speculation. Dick usually wrote in a hurry and for money, and sometimes under the influence of drugs or a recent and urgent personal religious revelation.

Peter Woit on Sean Carroll’s “Beyond Falsifiability” Paper

Peter Woit in Not Even Wrong:

HomepagephotoSean Carroll has a new paper out defending the Multiverse and attacking the naive Popperazi, entitled Beyond Falsifiability: Normal Science in a Multiverse. He also has a
Beyond Falsifiability blog post here.

Much of the problem with the paper and blog post is that Carroll is arguing against a straw man, while ignoring the serious arguments about the problems with multiverse research. The only explanation of the views he is arguing against is the following passage:

a number of highly respected scientists have objected strongly to the idea, in large part due to a conviction that what happens outside the universe we can possibly observe simply shouldn’t matter [4, 5, 6, 7]. The job of science, in this view, is to account for what we observe, not to speculate about what we don’t. There is a real worry that the multiverse represents imagination allowed to roam unfettered from empirical observation, unable to be tested by conventional means. In its strongest from, the objection argues that the very idea of an unobservable multiverse shouldn’t count as science at all, often appealing to Karl Popper’s dictum that a theory should be falsifiable to be considered scientific.

The problem here is that none of those references contain anything like the naive argument that if we can’t observe something, it “simply shouldn’t matter”, or one should not speculate about it, or it “shouldn’t count as science at all.”

JOHN FREEMAN ON THE PRESIDENCY OF DONALD TRUMP

John Freeman in Literary Hub:

ScreenHunter_2939 Jan. 20 17.48By the time you read this, what I am about to remind you of will be old news, but bear with me. The media moves at such velocity these days it is often useful to circle back to recent car wrecks and examine the smoking tangle of metal and human form. Here’s one of those incidents. Standing on the front lawn of the White House just before Christmas 2017, in his trademark blue wool car coat, yellowish hair unmoved by wind and cold, the President of the United States bragged that his party’s tax bill would “mostly benefit the middle class… This is going to be one of the great gifts to the middle-income people of this country that they’ve ever gotten for Christmas.”

This was a lie.

The tax cut Trump signed into law at the end of 2017 will benefit mostly the wealthy, and not just the wealthy, but the obscenely rich. The private jet and tax haven class. Many middle-class families will see almost no benefit at all.

The poor will actually see a tax increase.

Depending on who is counting, it was the 1,629th false or misleading statement made by Trump, and an especially cruel one in these times of bewildering inequality.

Australia was ruined the moment Europeans set foot there

Nicholas Shakespeare at The Spectator:

Many believed in Australia for 1,000 years before its discovery. There had to be a commensurate weight The-Bounty— somewhere Down Under — to counter the northern land mass; an ‘unknown Southland’ which was crucial to maintaining the balance of the world. To confuse matters, this theoretical continent was dubbed for a while Austrialia del Espiritu Santo — in honour of the House of Austria.

A socially awkward Lincolnshireman, Matthew Flinders, in 1804, was the originator of Australia as the name for what had for centuries been called New Holland, but two French sailors, an aristocratic cartographer, Louis Freycinet, and a manipulative, one-eyed anthropologist, François Péron, showed for the first time the continent’s actual shape.

From the late 1700s, galvanised by the loss of their American colonies, the French dispatched seven expeditions in 30 years to seek a huge landmass known as Gonneville Land, named after a French sailor blown off course in 1503. None of these expeditions had marvellous outcomes for their commanders. Marion was eaten by Maoris, Kerguelen convicted of fraud, D’Entrecasteaux died of scurvy, while the most famous, La Pérouse, vanished without trace.

Beyond the Bitcoin Bubble

Steven Johnson in The New York Times:

layer innocent nothing argue pottery winner cotton menu task slim merge maid

BitcoinThe sequence of words is meaningless: a random array strung together by an algorithm let loose in an English dictionary. What makes them valuable is that they’ve been generated exclusively for me, by a software tool called MetaMask. In the lingo of cryptography, they’re known as my seed phrase. They might read like an incoherent stream of consciousness, but these words can be transformed into a key that unlocks a digital bank account, or even an online identity. It just takes a few more steps. On the screen, I’m instructed to keep my seed phrase secure: Write it down, or keep it in a secure place on your computer. I scribble the 12 words onto a notepad, click a button and my seed phrase is transformed into a string of 64 seemingly patternless characters:

1b0be2162cedb2744d016943bb14e71de6af95a63af3790d6b41b1e719dc5c66

This is what’s called a “private key” in the world of cryptography: a way of proving identity, in the same, limited way that real-world keys attest to your identity when you unlock your front door. My seed phrase will generate that exact sequence of characters every time, but there’s no known way to reverse-engineer the original phrase from the key, which is why it is so important to keep the seed phrase in a safe location. That private key number is then run through two additional transformations, creating a new string:

0x6c2ecd6388c550e8d99ada34a1cd55bedd052ad9

That string is my address on the Ethereum blockchain. Ethereum belongs to the same family as the cryptocurrency Bitcoin, whose value has increased more than 1,000 percent in just the past year. Ethereum has its own currencies, most notably Ether, but the platform has a wider scope than just money. You can think of my Ethereum address as having elements of a bank account, an email address and a Social Security number. For now, it exists only on my computer as an inert string of nonsense, but the second I try to perform any kind of transaction — say, contributing to a crowdfunding campaign or voting in an online referendum — that address is broadcast out to an improvised worldwide network of computers that tries to verify the transaction.

philip larkin and his mother

2130Dalya Alberge at The Guardian:

He was terrified of marriage, living a life of tangled relationships with women who became his muses. Poet Philip Larkin’s view of marriage may partly have been coloured by his mother’s warnings of its disadvantages, previously unpublished letters reveal.

In 1952, Eva Larkin told her son: “Marriage would be no certain guarantee as to socks being always mended, or meals ready when they are wanted. Neither would it be wise to marry just for those comforts. There are other things just as important.”

The following year, she quoted from a George Bernard Shaw novel in offering further relationship advice: “I have just finished reading Love Among the Artists … in which occurs this passage ‘No: it is marriage that kills the heart and keeps it dead. Better starve the heart than overfeed it. Better still to feed it only on fine food, like music’. In a way, I agree with him… Better to have lived a full life, I think.”

‘THIRD MILLENNIUM HEART’ BY URSULA ANDKJÆR OLSEN

TmhNaheed Patel at The Quarterly Conversation:

The strange and ferocious narrative voice of The Third Millennium Heart, of both victim and abuser; the poet’s rejection of a normative structure; her antipathy towards the ubiquitous pressure of being a likeable female; her disruptive vision of human beings as human-animal-machine hybrids—qualifies Olsen as a foremother, in my view.

And helping Olsen to become canon is the English translation by Katrine Ogaard Jensen, who makes sure that the language remains as undomesticated as the poetry itself. Friedrich Schleiermacher, in a seminal lecture to the Berlin Academy of Sciences, titled “On The Different Methods of Translation”, said: “Either the translator leaves the writer in peace as much as possible and moves the reader toward him, or he leaves the reader in peace as much as possible and moves the writer toward him.” In her translator’s note, Jensen mentions that she breaks lines when she susses the opportunity for wordplay, and to accommodate the victim/abuser ambiguity of the third millennium heart character. Inventing words with meticulous boldness, Jensen never wastes an opportunity to jar the reader out of complacent comprehension. The resulting lexicon is bizarre and beautiful: namedrunk, exobrain, exoheart, sweat-embroidery, society-suckling, heavenmechanic, soulfisherman, paranoia-carcass, etc.—and makes it quite clear to the reader that leaving them in peace was never on the table.

Saturday Poem

Under One Small Star

My apologies to chance for calling it necessity.
My apologies to necessity if I'm mistaken, after all.
Please, don't be angry, happiness, that I take you as my due.
May my dead be patient with the way my memories fade.
My apologies to time for all the world I overlook each second.
My apologies to past loves for thinking that the latest is the first.
Forgive me, distant wars, for bringing flowers home.
Forgive me, open wounds, for pricking my finger.
I apologize for my record of minuets to those who cry from the depths.
I apologize to those who wait in railway stations for being asleep today at five a.m.
Pardon me, hounded hope, for laughing from time to time.
Pardon me, deserts, that I don't rush to you bearing a spoonful of water.
And you, falcon, unchanging year after year, always in the same cage,
your gaze always fixed on the same point in space,
forgive me, even if it turns out you were stuffed.
My apologies to the felled tree for the table's four legs.
My apologies to great questions for small answers.
Truth, please don't pay me much attention.
Dignity, please be magnanimous.
Bear with me, O mystery of existence, as I pluck the occasional thread from your train.
Soul, don't take offense that I've only got you now and then.
My apologies to everything that I can't be everywhere at once.
My apologies to everyone that I can't be each woman and each man.
I know I won't be justified as long as I live,
since I myself stand in my own way.
Don't bear me ill will, speech, that I borrow weighty words,
then labor heavily so that they may seem light.

Akeel Bilgrami on failures of inference: liberalism and contemporary populism

Akeel Bilgrami in The Hindu:

19THPOPULISMIt is a measure of the abject inadequacy of liberal thought today that all it can bring to the political arena, and to public discourse generally, is high indignation at the tawdriness of what it dismissively describes as ‘populism’. Even when, on occasion, some of the more serious liberal ideologues try to do better, there is a tendency to produce a pattern of analysis that goes roughly like this. They observe everywhere the dissatisfaction of ordinary people (by ordinary people I just mean working and workless people away from the centres of power and privilege). They observe too — with dismay — that these dissatisfactions result in alarming electoral decisions that succumb to the dubious appeal of ‘populist’ politicians, who will often only increase their dissatisfaction. They allow themselves no good account (certainly no self-critical account) of how and why this has come to pass. They, thus, draw the conclusion that the fault lies in the people themselves for (at best) their gullibility or (at worst) their xenophobia or racism or communalism… And so, finally, they rest with the hope that the decencies of their own liberal orthodoxies (whether it is the Clintonite Democratic Party — which includes the arch Clintonite, Barack Obama — or the ‘Remainers’ in Britain, or the Congress technocratic elite represented in the past by Manmohan Singh and his economic advisers) will one day return to win the day. It never occurs to them through these smug cogitations that this analysis has no bite, hardly even a jaw.

Sean Carroll on the thorny issue of the scientific status of multiverse cosmological models

Sean Carroll in Preposterous Universe:

X2Ji862uCosmological models that invoke a multiverse – a collection of unobservable regions of space where conditions are very different from the region around us – are controversial, on the grounds that unobservable phenomena shouldn’t play a crucial role in legitimate scientific theories. I argue that the way we evaluate multiverse models is precisely the same as the way we evaluate any other models, on the basis of abduction, Bayesian inference, and empirical success. There is no scientifically respectable way to do cosmology without taking into account different possibilities for what the universe might be like outside our horizon. Multiverse theories are utterly conventionally scientific, even if evaluating them can be difficult in practice.

This is well-trodden ground, of course. We’re talking about the cosmological multiverse, not its very different relative the Many-Worlds interpretation of quantum mechanics. It’s not the best name, as the idea is that there is only one “universe,” in the sense of a connected region of space, but of course in an expanding universe there will be a horizon past which it is impossible to see. If conditions in far-away unobservable regions are very different from conditions nearby, we call the collection of all such regions “the multiverse.”

There are legitimate scientific puzzles raised by the multiverse idea, but there are also fake problems. Among the fakes is the idea that “the multiverse isn’t science because it’s unobservable and therefore unfalsifiable.” I’ve written about this before, but shockingly not everyone immediately agreed with everything I have said.

Back in 2014 the Edge Annual Question was “What Scientific Theory Is Ready for Retirement?”, and I answered Falsifiability. The idea of falsifiability, pioneered by philosopher Karl Popper and adopted as a bumper-sticker slogan by some working scientists, is that a theory only counts as “science” if we can envision an experiment that could potentially return an answer that was utterly incompatible with the theory, thereby consigning it to the scientific dustbin. Popper’s idea was to rule out so-called theories that were so fuzzy and ill-defined that they were compatible with literally anything.
