Most people are familiar with white noise, that static sound of an air conditioner that lulls us to sleep by drowning out any background noise.
Except technically, the whirl of a fan or hum of the AC isn’t white noise at all. Many of the sounds we associate with white noise are actually pink noise, or brown, or green, or blue. In audio engineering, there’s a whole rainbow of noise colors, each with its own unique properties, that are used to produce music, help relaxation, and describe natural rhythms like the human heartbeat. If you know what to look for, you can start to notice the colors of the noise that make up the soundscape around us.
If you decompose a sound wave, you can break it down into two fundamental characteristics: frequency, which is how fast the waveform is vibrating per second (one hertz is one vibration per second), and amplitude (sometimes measured as “power”), or the size of the waves. The noise types are named for a loose analogy to the colors of light: White noise, for example, contains all the audible frequencies, just like white light contains all the frequencies in the visible range.
In musical sound waves, the frequencies are spaced at intervals that we find pleasing to the ear, creating a harmonic structure that gives a sound its unique tone quality, or timbre. (This is what makes the same note sound different on a flute than it does on a violin.) The noises we hear every day—boots stomping across the floor, a car honking outside, the jingling of keys—are made up of sporadic waveforms, a random distribution of frequency and amplitude.
And then, in a separate category, there are the colored noises. Unlike the inconsistent bang of a drum or shouting voice, these sounds are a continuous signal, but they aren’t exactly pleasant. The word “noise” actually comes from a Latin word for nausea; in audio engineering, the term describes any unwanted information that interferes with the desired signal, like static on the radio.
Pure white noise sounds like that hissy “shhh” that happens when the TV or radio is tuned to an unused frequency. It’s a mixture of all the frequencies humans can hear (about 20 Hz to 20 kHz), fired off randomly with equal power at each—like 20,000 different tones all playing at the same time, mixed together in a constantly changing, unpredictable sonic stew.
The other colors are similar to white noise, but with more energy concentrated at either the high or low end of the sound spectrum, which subtly changes the nature of the signal. Pink noise, for example, is like white noise with the bass cranked up. It’s a “shhh” sound with a low rumble mixed in, like the soft roar of a rainstorm.
Pink noise sounds less harsh than white noise because humans don’t hear linearly. We hear in octaves, or the doubling of a frequency band, which means we perceive as much sonic space between 30-60 Hz as between 10,000-20,000 Hz. We’re also more sensitive to higher frequencies (one to four kHz, which is about the frequency of a crying baby, sounds the loudest), so white noise, which has the same intensity at even the highest tones, can sound way too bright to our ears. The energy in pink noise drops off by half as the frequency doubles, so every octave has equal power, which sounds more balanced.
Even Iran, with its abysmal human-rights record, feels comfortable criticizing the U.S.
In his sovereignty-centric speech Tuesday to the UN General Assembly, President Donald Trump threatened to “totally destroy North Korea”; called Iran “a corrupt dictatorship” whose “chief exports are violence, bloodshed, and chaos”; and said Venezuela’s government “has inflicted terrible pain and suffering on the good people of that country.”
The remarks have prompted the expected reactions from Iran, whose foreign minister called it an “ignorant hate speech [that] belongs in medieval times,” and Venezuela’s foreign minister, who countered: “Trump is not the president of the world ... he cannot even manage his own government.” North Korea, whose nuclear-weapons and missile programs have raised tensions with its neighbors and the U.S., is yet to respond.
On Tuesday, the late-night host once again devoted his show to the politics of American health care. This time, though, he offered indignation rather than tears.
“By the way, before you post a nasty Facebook message saying I’m politicizing my son’s health problems, I want you to know: I am politicizing my son’s health problems.”
That was Jimmy Kimmel on Tuesday evening, in a monologue reacting to the introduction of Graham-Cassidy, the (latest) bill that seeks to replace the Affordable Care Act. Kimmel had talked about health care on his show before, in May—when, after his newborn son had undergone open-heart surgery to repair the damage of a congenital heart defect, he delivered a tearfully personal monologue sharing the experience of going through that—and acknowledging that he and his family were lucky: They could afford the surgery, whatever it might cost. Kimmel concluded his speech by, yes, politicizing his son’s health problems: He emphasized how important it is for lower- and middle-class families to have comprehensive insurance coverage, with protections for people with preexisting conditions. “No parent,” he said, speaking through tears, “should ever have to decide if they can afford to save their child’s life. It shouldn’t happen.”
Its faith-based 12-step program dominates treatment in the United States. But researchers have debunked central tenets of AA doctrine and found dozens of other treatments more effective.
J.G. is a lawyer in his early 30s. He’s a fast talker and has the lean, sinewy build of a distance runner. His choice of profession seems preordained, as he speaks in fully formed paragraphs, his thoughts organized by topic sentences. He’s also a worrier—a big one—who for years used alcohol to soothe his anxiety.
J.G. started drinking at 15, when he and a friend experimented in his parents’ liquor cabinet. He favored gin and whiskey but drank whatever he thought his parents would miss the least. He discovered beer, too, and loved the earthy, bitter taste on his tongue when he took his first cold sip.
His drinking increased through college and into law school. He could, and occasionally did, pull back, going cold turkey for weeks at a time. But nothing quieted his anxious mind like booze, and when he didn’t drink, he didn’t sleep. After four or six weeks dry, he’d be back at the liquor store.
More comfortable online than out partying, post-Millennials are safer, physically, than adolescents have ever been. But they’re on the brink of a mental-health crisis.
One day last summer, around noon, I called Athena, a 13-year-old who lives in Houston, Texas. She answered her phone—she’s had an iPhone since she was 11—sounding as if she’d just woken up. We chatted about her favorite songs and TV shows, and I asked her what she likes to do with her friends. “We go to the mall,” she said. “Do your parents drop you off?,” I asked, recalling my own middle-school days, in the 1980s, when I’d enjoy a few parent-free hours shopping with my friends. “No—I go with my family,” she replied. “We’ll go with my mom and brothers and walk a little behind them. I just have to tell my mom where we’re going. I have to check in every hour or every 30 minutes.”
Those mall trips are infrequent—about once a month. More often, Athena and her friends spend time together on their phones, unchaperoned. Unlike the teens of my generation, who might have spent an evening tying up the family landline with gossip, they talk on Snapchat, the smartphone app that allows users to send pictures and videos that quickly disappear. They make sure to keep up their Snapstreaks, which show how many days in a row they have Snapchatted with each other. Sometimes they save screenshots of particularly ridiculous pictures of friends. “It’s good blackmail,” Athena said. (Because she’s a minor, I’m not using her real name.) She told me she’d spent most of the summer hanging out alone in her room with her phone. That’s just the way her generation is, she said. “We didn’t have a choice to know any life without iPads or iPhones. I think we like our phones more than we like actual people.”
The foundation of Donald Trump’s presidency is the negation of Barack Obama’s legacy.
It is insufficient to statethe obvious of Donald Trump: that he is a white man who would not be president were it not for this fact. With one immediate exception, Trump’s predecessors made their way to high office through the passive power of whiteness—that bloody heirloom which cannot ensure mastery of all events but can conjure a tailwind for most of them. Land theft and human plunder cleared the grounds for Trump’s forefathers and barred others from it. Once upon the field, these men became soldiers, statesmen, and scholars; held court in Paris; presided at Princeton; advanced into the Wilderness and then into the White House. Their individual triumphs made this exclusive party seem above America’s founding sins, and it was forgotten that the former was in fact bound to the latter, that all their victories had transpired on cleared grounds. No such elegant detachment can be attributed to Donald Trump—a president who, more than any other, has made the awful inheritance explicit.
The meaning of Trump’s fire and fury foreign policy.
Above all else, President Donald Trump wants the world to see him as strong. He has repeatedly described himself as “militaristic,” and his cabinet as a group of “killers.” He relishes saying the supposedly unsayable. When he spoke at the UN General Assembly yesterday, he surely wanted his listeners to be awed by his toughness. Better, as Machiavelli said, to be feared than loved.
Trump’s team loaded his speech with harsh words and phrases. He promised to destroy North Korea if attacked. He called the Iran nuclear deal an embarrassment. He rejected globalism and spoke at length about the benefits of sovereignty, nationalism, and patriotism.
But when one moves beyond the image Trump tries to project and looks at the consequences of his words, things look quite different. His UN speech was one of the least effective, weakest, and indecisive ever given by an American president. It’s not that it failed against some arbitrary standard set by the foreign-policy establishment he despises. It failed on its own terms. And how it failed tells us something important about where his foreign policy is headed.
“If the world’s major powers can’t agree on what the UN is for, what does that mean for its future?”
Since the Second World War, American presidents have repeatedly gone before the United Nations General Assembly and made a similar argument: The United States has national interests just like any other country, but in the modern era those interests are increasingly international in scope and shared by people around the world, requiring more of the multilateral cooperation that the UN was founded to foster.
John F. Kennedy argued that nuclear weapons necessitated “one world and one human race, with one common destiny” guarded by one “world security system,” since “absolute sovereignty no longer assures us of absolute security.” Richard Nixon spoke of a “world interest” in reducing economic inequality, protecting the environment, and upholding international law, declaring that the “profoundest national interest of our time” is the “preservation of peace” through international structures like the UN. In rejecting tribalism and the walling-off of nations, Barack Obama asserted that “giving up some freedom of action—not giving up our ability to protect ourselves or pursue our core interests, but binding ourselves to international rules over the long term—enhances our security.” These presidents practiced what they preached to varying degrees, and there’s long been a debate in the United States about the extent to which America’s sovereign powers should be ceded to international organizations, but in broad strokes the case for global engagement was consistent.
Jeffrey Gerrish’s decision to cast a ballot in Virginia isn’t so much a gotcha on him as it is on the president’s voter-fraud commission.
Jeffrey Gerrish made a mistake. Not a big one, although he did break the law. But it’s a mistake many people make, and for the most part, they aren’t called out by the Senate Finance Committee and in the pages of The New York Times.
Most of the people who make the error, however, are not nominees of a president who has alleged that there were 3 to 5 million fraudulent votes cast in the 2016 election, or who empaneled a commission to consider voter fraud that is on a dubious hunt to try to validate that wild, unsubstantiated claim. Jeffrey Gerrish, however, is President Trump’s nominee to be deputy U.S. trade representative, so it happens that investigators realized he cast his vote in the 2016 election in Virginia, even though he had moved to Maryland—a far less competitive state in national elections.
As Trump considers military options, he’s drawing unenforceable red lines.
Speaking before the UN General Assembly today, President Donald Trump announced that, unless North Korea gives up its nuclear weapons and ballistic missile programs, “the United States will have no choice but to totally destroy” the country. He sounded almost excited as he threatened, “Rocket Man is on a suicide mission for himself and for his regime.”
North Korea is a serious problem, and not one of Trump’s making—the last four American presidents failed to impede North Korea’s progress towards a nuclear weapon. President George H.W. Bush took unilateral action, removing U.S. nuclear weapons and reducing America’s troop levels in the region, hoping to incentivize good behavior; Presidents Bill Clinton and George W. Bush tried to negotiate restrictions; President Barack Obama mostly averted his eyes. North Korea defied them all.
"Dave, stop. Stop, will you? Stop, Dave. Will you stop, Dave?” So the supercomputer HAL pleads with the implacable astronaut Dave Bowman in a famous and weirdly poignant scene toward the end of Stanley Kubrick’s 2001: A Space Odyssey. Bowman, having nearly been sent to a deep-space death by the malfunctioning machine, is calmly, coldly disconnecting the memory circuits that control its artificial “ brain. “Dave, my mind is going,” HAL says, forlornly. “I can feel it. I can feel it.”
I can feel it, too. Over the past few years I’ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn’t going—so far as I can tell—but it’s changing. I’m not thinking the way I used to think. I can feel it most strongly when I’m reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I’d spend hours strolling through long stretches of prose. That’s rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I’m always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle.
