"My rule is simply to do for my students exactly what I hope someone else will do for my sons when the time comes: I teach them to have faith in themselves and in their own compass, to listen to nature to find truth, to love knowledge for the sake of itself, and to strive for greatness."
"Bell Labs had been a kind of holy place of solid state physics since the 1950's when it was built up by Shockley after the invention of the transistor. I had no idea at the time of the significance of this placement, but I did notice during my job talk that everybody understood what I was saying immediately â this had never happened before â and that the audience had an irresistible urge to interrupt, heckle, and argue about the subject matter loudly among themselves during the talk so as to lob hand grenades into it, just like back-benchers do in the House of Commons. Being a combative person I rather liked this and lobbed a few grenades of my own to maintain control of my seminar. I later came to understand that this heckling was a sign of respect from these people, that the ability to handle it was a test of a person's worth, and that polite silence from them was an extremely bad sign, amounting to Pauli's famous criticism that the speaker was "not even wrong.""
"I learned about X-ray diffraction, neutron scattering, raman scattering, infrared absorption spectroscopy, heat capacity, transport, time-dependent transport, magnetic resonance, electron diffraction, electron energy loss spectroscopy â all the experimental techniques that constitute the eyes and ears of modern solid state physics. As this occurred I slowly became disillusioned with the reductionist ideal of physics, for it was completely clear that the outcome of these experiments was almost always impossible to predict from first principles, yet was right and meaningful and certainly regulated by the same microscopic laws that work in atoms. Only many years later did I finally understand that this truth, which seems so natural to solid state physicists because they confront experiments so frequently, is actually quite alien to other branches of physics and is vigorously repudiated by many scientists on the grounds that things not amenable to reductionist thinking are not physics."
"The world is full of intelligent, well-meaning people who, for one reason or another, did not attend university but are nonetheless well-read and educated. Out there on the prairie lost opportunities of youth were the rule rather than the exception, and I slowly became disabused of the myth of the Bright Young Thing and have not believed in it since."
"Oklahoma is laid back and rather beautiful, with rolling brown hills not unlike the ones in California. The Pershing missiles, on the other hand, were not beautiful. They were horrible weapons of war â solid-fuel rockets five feet in diameter at the base, long as a moving van, and capable of throwing a tactical nuclear warhead 500 miles. They were launched from trucks and required a team of 10 men to service and fire. The most interesting thing I learned during this time was how small a nuclear warhead was. The nose cone of a Pershing is only about 18 inches in diameter at the base. I had not been interested at all in nuclear weaponry as a student, and so I had never thought through carefully about their "efficiency". It is sobering thought that these missiles were actually deployed in continental Europe in those days and that on at least one occasion, namely the 1973 Arab-Israel war, there was an alert serious enough to leave the commanding officers trembling."
"He has no credibility left."
"Human beingsâany one of us, and our species as a wholeâare not all-important, not at the center of the world. That is the one essential piece of information, the one great secret, offered by any encounter with the woods or the mountains or the ocean or any wilderness or chunk of nature or patch of night sky."
"Bill McKibben has long said, when people ask him what's the most significant thing you can do for the climate, "Stop being an individual; join something.""
"Bill McKibben, a leading champion in the fight against climate change"
"McKibben understands that a central goal of movement leadership is to create more leaders, not more followers."
"I also thank Bill McKibben and his 350.org colleagues for the most important work in the world, and the most unending."
""We had no money and no organization, so we figured we'd be doing well if we could organize a hundred of these things by April 14. And that would have been about a hundred more global warming rallies than there had been," he told Democracy Now! Instead, McKibben tapped a rich vein of discontent around the United States. "People were really eager to finally be able to take action about this," said the amazed activist, "and the thing has just kinda exploded." More than fourteen hundred Step It Up rallies took place in all fifty states in April 2007. McKibben followed with another Step It Up Day seven months later, which involved hundreds of thousands of people around the country, including eighty members of Congress."
"Bill McKibben wrote, âWe live in a post-natural world.â But did âNatureâ in this sense ever exist? Or was it rather the deification of the human that gave it an illusory apartness from ourselves? Now that non-human agencies have dispelled that illusion, we are confronted suddenly with a new task: that of finding other ways in which to imagine the unthinkable beings and events of this era."
"Think about what your town is doing about environmental pollution before you go to Washington with radical environmentalist Bill McKibben to get arrested. I mean no lack of deference to McKibben or his followers. But there is plenty of work to go around, as all the movements that came after 1963 - women's, anti-war, and LGBTQ -- and gained power from the example that was set during the 1963 March on Washington, still show us."
"[D]ata from the World Meteorological Agency show that, as the U.N. Secretary-General, AntĂłnio Guterres, told the {COP28} global climate talks in Dubai last week, we can safely say, even with weeks to go, that 2023 will take the title {as the world's hottest year on record}. . . . And yet . . . [a]lmost simultaneous with the breakout in temperature, there was a breakout in the installation of renewable energy, especially solar power, around the world. . . . {T}he cost of clean energy has dropped so far that it is now possible that saving the planet might be a corollary of saving cash. This ongoing drop in price is more than a decade old, but sometime in the past few years it crossed an invisible line, making it cheaper than hydrocarbons, and this was the year when that reality finally translated into dramatic action on the ground. . . . There are plenty of other technologies weâre [currently] spending money on, including small nuclear reactors and giant carbon-sucking machines, that may or may not someday play a role in the climate fight, but, for all the furor they produce, they seem unlikely to make much difference anytime soon. In the next few years, while the planetâs climate system teeters on the edge of breaking, itâs sun, wind, and batteries that matter. Theyâre cheap, and theyâre ready."
"Fair or not, boomers and the Silent Generation have about 70% of the countryâs money, compared with about 5% for millennials. So if you want to push around Washington, or Wall Street, or your state capital, it helps to have some people with hairlines like mine."
"So now we have some sense of what itâs like: a full-on global-scale crisis, one that disrupts everything. Normal lifeâshopping for food, holding a wedding, going to work, seeing your parentsâshifts dramatically. The world feels different, with every assumption about safety and predictability upended. Will you have a job? Will you die? Will you ever ride a subway again, or take a plane? Itâs unlike anything weâve ever seen. The upheaval that has been caused by Covid-19 is also very much a harbinger of global warming. Because humans have fundamentally altered the physical workings of planet Earth, this is going to be a century of crises, many of them more dangerous than what weâre living through now. The main question is whether weâll be able to hold the rise in temperature to a point where we can, at great expense and suffering, deal with those crises coherently, or whether they will overwhelm the coping abilities of our civilization... The pandemic provides some useful sense of scaleâsome sense of how much weâre going to have to change to meet the climate challenge."
"On May 23, at the end of the last massive school strike, Thunberg and 46 other youth activists released an open letter to The Guardian urging adults to join in next time. Because, as they pointed out, there are limits to what young people can do on their own. If you canât vote, and if you donât own stocks, then your ability to pull the main levers of power is limited. They wrote: âSorry if this is inconvenient for you. But this is not a single-generation job. Itâs humanityâs job.â"
"What do Ben and Jerryâs, an 800,000-member South African trade union, countless college professors, a big chunk of Amazonâs Seattle workforce, and more high school students than you can imagine have in common? Theyâre all joining in a massive climate strike this coming Friday, September 20 â a strike that will likely register as the biggest day of climate action in the planetâs history."
"The longer I think about @DNC insisting no-one hold a climate debate, the sillier it seems. We've literally never talked about this issue in a presidential debate, and we literally have to deal with it immediately. I don't understand why we shouldn't devote a night to it."
"Single most important stat on the planet: CO2 rose 3.5 parts per million last year, 2nd-highest annual rise on record. This is legit scary"
"The dramatic uncertainty that lies ahead may be the most frightening development of all... the most likely scenarios...are more than disturbing enough. Long before we get to tidal waves or smallpox, long before we choke to death or stop thinking clearly, we will need to concentrate on the most mundane and basic facts: everyone needs to eat every day, and an awful lot of us live near the ocean... Where I live, itâs the seasons: winter doesnât reliably mean winter anymore, and so the way weâve always viscerally told time has begun to break down..."
"But in August 2018, a massive new study found something just as frightening: crop pests were thriving in the new heat. âIt gets better and better for them,â said one University of Colorado researcher. Even if we hit the UN target of limiting temperature rise to two degrees Celsius, pests should cut wheat yields by 46 percent, corn by 31 percent, and rice by 19 percent. âWarmer temperatures accelerate the metabolism of insect pests like aphids and corn borers at a predictable rate,â the researchers found. âThat makes them hungrier[,] and warmer temperatures also speed up their reproduction.â"
"A team of British researchers released a study demonstrating that even if you can grow plenty of food, the transportation system that distributes it runs through just fourteen major choke-points, and those are vulnerable to â you guessed it â massive disruption from climate change. For instance, U.S. rivers and canals carry a third of the worldâs corn and soy, and theyâve been frequently shut down or crimped by flooding and drought in recent years... âItâs the glide path to a perfect storm,â said one of the reportâs authors."
"If we keep raising carbon dioxide levels, we may not be able to think straight anymore. At a thousand parts per million (which is within the realm of possibility for 2100), human cognitive ability falls 21 percent. âThe largest effects were seen for Crisis Response, Information Usage, and Strategy,â a Harvard study reported, which is too bad, as those skills are what we seem to need most."
"Consider this: as ice sheets melt, they take weight off land, and that can trigger earthquakes â seismic activity is already increasing in Greenland and Alaska. Meanwhile, the added weight of the new seawater starts to bend the Earthâs crust. âThat will give you a massive increase in volcanic activity. Itâll activate faults to create earthquakes, submarine landslides, tsunamis, the whole lot,â explained the director of University College Londonâs Hazard Centre. Such a landslide happened in Scandinavia about eight thousand years ago, as the last Ice Age retreated and a Kentucky-size section of Norwayâs continental shelf gave way, âplummeting down to the abyssal plain and creating a series of titanic waves that roared forth with a vengeance,â wiping all signs of life from coastal Norway to Greenland and âdrowning the Wales-sized landmass that once connected Britain to the Netherlands, Denmark, and Germany.â When the waves hit the Shetlands, they were sixty-five feet high."
"Year after year throughout the last two decades theyâve made more money than any company in the history of money. But poor people around the world are already paying for those profits, and every generation that follows us now will pay as well, because the âExxon positionâ has helped take us over one tipping point after another. Their sins of emission, like so many other firms and individuals, are bad. But their sins of omission are truly inexcusable."
"ExxonMobil, the worldâs largest and most powerful oil company, knew everything there was to know about climate change by the mid-1980s, and then spent the next few decades systematically funding climate denial and lying about the state of the science.... But though we know now that behind the scenes Exxon understood precisely what was going on, in public they feigned ignorance or worse.... Thanks to Exxonâs willingness to sucker the world, that world is now a chaotic mess."
"...as early as 1977, Exxon (now ExxonMobil, one of the worldâs largest oil companies) knew that its main product would heat up the planet disastrously. This did not prevent the company from then spending decades helping to organize the campaigns of disinformation and denial that have slowedâperhaps fatallyâthe planetâs response to global warming....Exxon responded, instead, by helping to set up or fund extreme climate-denial campaigns....The company worked with veterans of the tobacco industry to try and infuse the climate debate with doubt."
"If it is wrong to wreck the planet, then it is wrong to profit from that wreckage."
"The logic of divestment couldn't be simpler: if it's wrong to wreck the climate, it's wrong to profit from that wreckage."
"Right now, plenty of people feel the peacefulness of their lives degraded by sprawl, or worry about the way consumerism has eroded the quality of our communities. For them, the idea of enough is not completely alien or distasteful, though it remains difficult to embrace. We've been told that it's impossible â that some force like evolution drives us on to More and Faster and Bigger. 'You can't stop progress.' But that's not true. We could choose to mature. That could be the new trick we share with each other, a trick as revolutionary as fire. Or even the computer."
"These new technologies are not yet inevitable. But if they blossom fully into being, freedom may irrevocably perish. This is a fight not only for the meaning of our individual lives, but for the meaning of our life together."
"They'll lead us bit by bit toward the revolutionary idea that we've grown about as powerful as it's wise to grow; that the rush of technological innovation that's marked the last five hundred years can finally slow, and spread out to water the whole delta of human possibility. But those decisions will only emerge if people understand the time for what it is: the moment when we stand precariously on the sharp ridge between the human past and the posthuman future, the moment when meaning might evaporate in a tangle of genes or chips."
"It worries me because it alters perception. TV, and the culture it anchors, and drowns out the subtle and vital information contact with the real world once provided."
"We believe that we live in the 'age of information,' that there has been an information 'explosion,' an information 'revolution.' While in a certain narrow sense that is the case, in many more important ways just the opposite is true. We also live at a moment of deep ignorance, when vital knowledge that humans have always possessed about who we are and where we live seems beyond our reach. An unenlightenment. An age of missing information."
"The expected effects of a sea-level rise typify the many consequences of a global warming. On the one hand, they are so big we literally can't understand them. If there is a significant polar melting, the Earth's center of gravity will shift, tipping the globe in such a way that the sea level might actually drop at Cape Horn and along the coast of IcelandâI read this in a recent EPA report and found that I didn't really understand what it meant to tip the Earth, through I was awed by the idea. On the other hand, the changes ultimately acquire a quite personal dimension: Should I put in a wall in front of my house? Does this taste salty to you? And, most telling of all, the human response to the problems, the utterly natural human attempt to preserve the old natural way of life in this postnatural world, creates entirely new consequences. The ocean rises; I build a wall; the marsh dies, and, with it, the fish."
"The greenhouse effect is a more apt name than those who coined it imagined. The carbon dioxide and trace gases act like the panes of glass on a greenhouseâthe analogy is accurate. But it's more than that. We have built a greenhouse, 'a human creation' where once there bloomed a sweet and wild garden."
"An idea, a relationship, can go extinct, just like an animal or a plant. The idea in this case is 'nature,' the separate and wild province, the world apart from man to which he adapted, under whose rules he was born and died. In the past, we spoiled and polluted parts of that nature, inflicted environmental 'damage.' But that was like stabbing a man with toothpicks: though it hurt, annoyed, degraded, it did not touch vital organs, block the path of lymph or blood. We never thought that we had wrecked nature. Deep down, we never really thought we could: it was too big and too old; its forcesâthe wind, the rain, the sunâwere too strong, too elemental. But, quite by accident, it turned out that the carbon dioxide and other gases we were producing in our pursuit of a better life... could alter the power of the sun, could increase its heat. And that increase could change the patterns of moisture and dryness, breed storms in new places, breed deserts...We have produced the carbon dioxideâwe are ending nature."
"Our comforting sense of the permanence of our natural world, our confidence that it will change gradually and imperceptibly if at all, is the result of a subtly warped perspective. Changes that can affect us can happen in our lifetime in our worldânot just changes like wars but bigger and more sweeping events. I believe that without recognizing it we have already stepped over the threshold of such a change; that we are at the end of nature. By the end of nature I do not mean the end of the world. The rain will still fall and the sun shine, though differently than before. When I say 'nature,' I mean a certain set of human ideas about the world and our place in it."
"The Volta is taken from a Federico Fellini book about his films, what he characterizes as a changing of scene, or a turnaround; a new scene to him is called Volta. Y'know, changing of time and the changeover. And Mars, we're just fascinated by science fiction so and it's something that ultimately looked as in anything I write, its meaning is always up to the listener. As the way we write songs and words, if it looks great on paper then to us it's like painting, so if it looks good meaning the second then people usually have a better interpretation than we ever would."
"Stop pathetically believing that you deserve Fame or Fame deserves you. It's yucky, and it's only making you miserable, so stop."
"One of the biggest complaints about season 4 is the time the judges spent heaping endless praise upon the choreographers rather than discussing the dancers, but in the case of hip-hop choreographers Napoleon and Tabitha Dumo [sic] (i.e., [NappyTabs], now and forever), that praise was well-deserved. The couple brought a lyrical storytelling sensibility to their routines that transformed hip-hop from hard-hitting abstract steps to something far more emotionally engaging."
"Somehow Napoleon and Tabitha have this ability... to put emotion into hip-hop routines and it really is a real talent."
"Honestly, I thought of him as a good-looking jock kind of guy, and I didnât think he was very artistic or very smart."
"I don't know how they do it but [Tabitha and Napoleon] love each other so much. They're this husband and wife duo that work together all the time and yet I've never seen them have an argument. I've never seen them kind'of roll their eyes at each other. I've never seen anything like that. They are the perfect example of a fabulous marriage."
"I love the So You Think You Can Dance show. I love it. I think itâs some of the best hours on TV. I think those dancers are extraordinary and, more so, I think those choreographers are uniformly amazing[...] And so I got two of who I think are the best choreographers on SYTYCD â Tabitha and Napoleon â to be involved in some movement elements. Because I think when dance is mediocre, itâs painful. But when dance is really impressive, it destroys."
"We work together so much; it's weird doing even an interview separately, ⌠[a]nd when we teach we vibe off each other. I'll start a joke, and Tabitha will finish it. I'll start choreographing, and she'll continue. We don't plan it like that; it just happens."
"Usually their choreography's a bit cotton candy..."
"I guess it's the first season... where I've been effected emotionally by hip-hop routines."
