The Fable of the Dragon-Tyrant

From CGP Grey, an animated version of philosopher Nick Bostrom’s The Fable of the Dragon-Tyrant.

Seeing that defeating the tyrant was impossible, humans had no choice but to obey its commands and pay the grisly tribute. The fatalities selected were always elders. Although senior people were as vigorous and healthy as the young, and sometimes wiser, the thinking was that they had at least already enjoyed a few decades of life. The wealthy might gain a brief reprieve by bribing the press gangs that came to fetch them; but, by constitutional law, nobody, not even the king himself, could put off their turn indefinitely.

Spiritual men sought to comfort those who were afraid of being eaten by the dragon (which included almost everyone, although many denied it in public) by promising another life after death, a life that would be free from the dragon-scourge. Other orators argued that the dragon has its place in the natural order and a moral right to be fed. They said that it was part of the very meaning of being human to end up in the dragon’s stomach. Others still maintained that the dragon was good for the human species because it kept the population size down. To what extent these arguments convinced the worried souls is not known. Most people tried to cope by not thinking about the grim end that awaited them.

For many centuries this desperate state of affairs continued. Nobody kept count any longer of the cumulative death toll, nor of the number of tears shed by the bereft. Expectations had gradually adjusted and the dragon-tyrant had become a fact of life. In view of the evident futility of resistance, attempts to kill the dragon had ceased. Instead, efforts now focused on placating it. While the dragon would occasionally raid the cities, it was found that the punctual delivery to the mountain of its quota of life reduced the frequency of these incursions.

Bostrom explains the moral of the story, which has to do with fighting aging:

The ethical argument that the fable presents is simple: There are obvious and compelling moral reasons for the people in the fable to get rid of the dragon. Our situation with regard to human senescence is closely analogous and ethically isomorphic to the situation of the people in the fable with regard to the dragon. Therefore, we have compelling moral reasons to get rid of human senescence.

The argument is not in favor of life-span extension per se. Adding extra years of sickness and debility at the end of life would be pointless. The argument is in favor of extending, as far as possible, the human health-span. By slowing or halting the aging process, the healthy human life span would be extended. Individuals would be able to remain healthy, vigorous, and productive at ages at which they would otherwise be dead.

I watched the video before reading Bostrom’s moral and thought it might have been about half a dozen other things (guns, climate change, agriculture, the Industrial Revolution, racism) before realizing it was more literal than that. Humanity has lots of dragons sitting on mountaintops, devouring people, waiting for a change in the world’s perspective or technology or culture to meet its doom.


Three Identical Strangers

Two men attending the same college in the early 80s kept getting mistaken for each other and when they met, they realized that they were actually twins. And then they met a third doppelganger, who turned out to the third triplet, all separated from each other at birth. Three Identical Strangers, a feature-length documentary that premiered at Sundance, tells the story of the three men: how they met, what happened after they were born, and “an extraordinary and disturbing secret that goes beyond their own lives”.


How to harvest nearly infinite energy from a spinning black hole

Well, this is a thing I didn’t know about black holes before watching this video. Because some black holes spin, it’s possible to harvest massive amounts of energy from them, even when all other energy sources in the far far future are gone. This process was first proposed by Roger Penrose in a 1971 paper.

The Penrose process (also called Penrose mechanism) is a process theorised by Roger Penrose wherein energy can be extracted from a rotating black hole. That extraction is made possible because the rotational energy of the black hole is located not inside the event horizon of the black hole, but on the outside of it in a region of the Kerr spacetime called the ergosphere, a region in which a particle is necessarily propelled in locomotive concurrence with the rotating spacetime. All objects in the ergosphere become dragged by a rotating spacetime. In the process, a lump of matter enters into the ergosphere of the black hole, and once it enters the ergosphere, it is forcibly split into two parts. For example, the matter might be made of two parts that separate by firing an explosive or rocket which pushes its halves apart. The momentum of the two pieces of matter when they separate can be arranged so that one piece escapes from the black hole (it “escapes to infinity”), whilst the other falls past the event horizon into the black hole. With careful arrangement, the escaping piece of matter can be made to have greater mass-energy than the original piece of matter, and the infalling piece has negative mass-energy.

This same effect can also be used in conjunction with a massive mirror to superradiate electromagnetic energy: you shoot light into a spinning black hole surrounded by mirrors, the light is repeatedly sped up by the ergosphere as it bounces off the mirror, and then you harvest the super-energetic light. After the significant startup costs, it’s basically an infinite source of free energy.


The storytellers who read aloud to Cuban cigar rollers

In a practice that started in 1865 and still continues today, lectores (storytellers) in Cuban cigar factories read to the workers while they roll cigars. They read the news, novels, horoscopes, recipes…it’s like a live daily radio show or podcast for the workers.

I’m not just a reader; I’m rather a cultural promoter of sorts. I usually try to bring topics that can influence their day-to-day, and help them face certain issues.

(Gee, that sounds like what I do here!) The practice started as a way to educate and entertain workers and eventually helped fuel the Cuban independence movement…a little knowledge goes a long way. Nowadays, the practice is less revolutionary. From a piece in The Economist about lectores:

The workers themselves choose the lectores. “This is the only job in Cuba that is democratically decided,” says an employee. The audience is demanding. Torcedores signal approval by tapping chavetas, oyster-shaped knives, on their worktables; slamming them on the floor shows displeasure. They vote on reading material: Ms Valdés-Lombillo recently finished “A Time to Die” by Wilbur Smith, a South African novelist, and “Semana Santa en San Francisco”, by Agustin García Marrero, a Cuban. When the readings get steamy, torcedores provide an accompaniment of suggestive sound effects. They laugh when a horoscope suggests that someone might inherit a fortune.

This piece in Mental Floss also contains some interesting tidbits:

One lectora, Maria Caridad Gonzalez Martinez, wrote 21 novels over her career. None were published; she simply read them all aloud to her audience.

Update: Anna in the Tropics is a Pulitzer Prize-winning play by Nilo Cruz in which the main action features a lector.

And a 1909 photograph by Lewis Hine, a lector reading to cigar workers in Tampa, FL.

Robot successfully assembles an Ikea chair

Fittingly using only off-the-shelf components, a team of researchers in Singapore built a robot capable of assembling a Stefan chair from Ikea (minus actually bolting it together). The assembly time was around 20 minutes, about 5-10 minutes slower than a typical human would take.

It took a few attempts to get it right. Early on, the robots dropped wooden pins, let go of parts too soon, and performed moves that did more to dismantle the chair than assemble it. Some moves required a part to be held by both robots at the same time, and since industrial robots are far stronger than Ikea furniture, a number of mistakes ended badly. “We bought four chair kits and broke a few of them,” said Pham.

Once the robot can fully assemble Ikea furniture in near-human timeframes, I propose we stop all robotics and AI research. When humanity no longer has to struggle with Ikea assembly, we can live like Scandinavian kings and not have to worry about AI murderbots killing us all (before they get bored, of course).


20 Years of Lauryn Hill

Yesterday, hip hop legend Lauryn Hill announced The Miseducation Of Lauryn Hill 20th Anniversary Tour 2018.

This summer marks the 20th anniversary of seminal hip-hop album The Miseducation Of Lauryn Hill, and Lauryn Hill is marking the occasion with a special anniversary tour dedicated to the album. Hill will be performing Miseducation in full, and each stop on the tour will feature “special guest performers” that haven’t been named yet. Plus, a portion of ticket sales will be donated to Hill’s MLH Foundation, which backs a huge group of charities built to help people all over the world-including the Africa Philanthropic Foundation, Appetite For Change, Apps & Girls, and the Equal Justice Initiative.

And Nerdwriter’s Evan Puschak, always with his ear to the ground (or perhaps with his ear to Drake’s Nice for What), just came out with this mini-doc celebrating of Hill’s music, influences, and people she’s influenced:

This might be one of the best Nerdwriter videos yet: no commentary, just clips of Hill performing and talking, music she was influenced by, and people & music that were influenced by her…an impressionistic portrait of a significant and uncompromising artist.


A lovely ode to stop motion animation

In this short film, animator and director Ainslie Henderson talks about how he designs puppets for his stop motion animations, creating a charming little stop motion music video in the process.

Puppet-making often begins by just gathering stuff, like materials that I find attractive. Wood and sticks and wire and leaves and flowers and petals and bits of broken electronics…things that have already had a life are lovely to have in puppets.


Kubrick’s 2001: A Space Odyssey, 50 years of the future

50 years ago this month, Stanley Kubrick’s 2001: A Space Odyssey premiered in the US. For this week’s issue of the New Yorker, Dan Chiasson looks at the cultural impact of the film, which got off to a rocky start.

Fifty years ago this spring, Stanley Kubrick’s confounding sci-fi masterpiece, “2001: A Space Odyssey,” had its premières across the country. In the annals of audience restlessness, these evenings rival the opening night of Stravinsky’s “Rite of Spring,” in 1913, when Parisians in osprey and tails reportedly brandished their canes and pelted the dancers with objects. A sixth of the New York première’s audience walked right out, including several executives from M-G-M. Many who stayed jeered throughout. Kubrick nervously shuttled between his seat in the front row and the projection booth, where he tweaked the sound and the focus. Arthur C. Clarke, Kubrick’s collaborator, was in tears at intermission. The after-party at the Plaza was “a room full of drinks and men and tension,” according to Kubrick’s wife, Christiane.

Chiasson references a 1966 profile of Kubrick in the New Yorker by Jeremy Bernstein, which catches the filmmaker in the act of making 2001.

In addition to writing and directing, Kubrick supervises every aspect of his films, from selecting costumes to choosing the incidental music. In making “2001” he is, in a sense, trying to second-guess the future. Scientists planning long-range space projects can ignore such questions as what sort of hats rocket-ship hostesses will wear when space travel becomes common (in “2001” the hats have padding in them to cushion any collisions with the ceiling that weightlessness might cause), and what sort of voices computers will have if, as many experts feel is certain, they learn to talk and to respond to voice commands (there is a talking computer in “2001” that arranges for the astronauts’ meals, gives them medical treatments, and even plays chess with them during a long space mission to Jupiter-“Maybe it ought to sound like Jackie Mason,” Kubrick once said), and what kind of time will be kept aboard a spaceship (Kubrick chose Eastern Standard, for the convenience of communicating with Washington). In the sort of planning that nasa does, such matters can be dealt with as they come up, but in a movie everything is immediately visible and explicit, and questions like this must be answered in detail. To help him find the answers, Kubrick has assembled around him a group of thirty-five artists and designers, more than twenty special-effects people, and a staff of scientific advisers. By the time the picture is done, Kubrick figures that he will have consulted with people from a generous sampling of the leading aeronautical companies in the United States and Europe, not to mention innumerable scientific and industrial firms. One consultant, for instance, was Professor Marvin Minsky, of M.I.T., who is a leading authority on artificial intelligence and the construction of automata. (He is now building a robot at M.I.T. that can catch a ball.) Kubrick wanted to learn from him whether and if the things that he was planning to have his computers do were likely to be realized by the year 2001; he was pleased to find out that they were.

A new book by Michael Benson, Space Odyssey: Stanley Kubrick, Arthur C. Clarke, and the Making of a Masterpiece, looks back at how the film was made. The visual effects are one of the reasons the film is so celebrated today; Vulture took a quick look at four of the most influential effects:

The ending of the film can still be puzzling after several viewings — deliberately so, according to Kubrick — but ScreenPrism took a crack at a literal explanation of the Giant Space Baby et al.:

Kubrick himself explained the plot of 2001 in a 1969 interview in just two paragraphs:

You begin with an artifact left on earth four million years ago by extraterrestrial explorers who observed the behavior of the man-apes of the time and decided to influence their evolutionary progression. Then you have a second artifact buried deep on the lunar surface and programmed to signal word of man’s first baby steps into the universe — a kind of cosmic burglar alarm. And finally there’s a third artifact placed in orbit around Jupiter and waiting for the time when man has reached the outer rim of his own solar system.

When the surviving astronaut, Bowman, ultimately reaches Jupiter, this artifact sweeps him into a force field or star gate that hurls him on a journey through inner and outer space and finally transports him to another part of the galaxy, where he’s placed in a human zoo approximating a hospital terrestrial environment drawn out of his own dreams and imagination. In a timeless state, his life passes from middle age to senescence to death. He is reborn, an enhanced being, a star child, an angel, a superman, if you like, and returns to earth prepared for the next leap forward of man’s evolutionary destiny.

And there’s much more to explore about 2001 in the kottke.org archives.


Pristine Restoration of a 9-Minute Silent Film of NYC Street Life from 1911

Last year, MoMA presented a nine-minute short film of locales around NYC that was shot in 1911.

This documentary travelogue of New York City was made by a team of cameramen with the Swedish company Svenska Biografteatern, who were sent around the world to make pictures of well-known places. (They also filmed at Niagara Falls and in Paris, Monte Carlo, and Venice, although New York 1911 is the only selection in the Museum’s collection.) Opening and closing with shots of the Statue of Liberty, the film also includes New York Harbor; Battery Park and the John Ericsson statue; the elevated railways at Bowery and Worth Streets; Broadway sights like Grace Church and Mark Cross; the Flatiron Building on Fifth Avenue; and Madison Avenue.

The film was only on the MoMA’s site for a brief time1 but lately some copies have popped up on YouTube, including the one embedded above. Note: this particular copy of the film has audio added and has been slowed down to a “natural rate”. I’d turn the sound off…the added foley effects are poorly done. If you want to see the original video, watch this one.

Update: This is a restoration of the film done by machine learning algorithms — it’s been upsampled to 4K & 60 fps, sharpened, and colorized.

The colorization doesn’t do it for me and there are some areas where the algorithms don’t do a very good job (halos around vignetted figures on the boat right at the beginning for example), but otherwise this is pretty impressive. It’s not as good as Peter Jackson’s team did with old WWI footage for They Shall Not Grow Old, but you can’t beat the price of this push-button approach.

  1. No idea why they took the video down. Are there licensing issues? Or are they just trying to force an artificial scarcity? Why not just leave it up as a permanent exhibit? If you’re an art museum, you should share the art you have access to as much and as widely as possible.


The most divisive work in all of modern art: all-white paintings

Modern art museum patrons are often confounded by all-white paintings like those of Robert Ryman. Like, what the hell? It’s just a white painting? “I could do that.” In this video, Vox’s Dean Peterson talks with The Whitney’s assistant curator Elisabeth Sherman about how you might approach thinking about minimalist art.

The art critic Peter Schjeldahl, writing about a retrospective of Ryman’s work for the New Yorker, gets at what the artist is attempting to communicate with his work:

Always, Ryman invites contemplation of the light that falls on his paintings (which when I saw them, on a recent cloudy day, was glumly tender as it filtered through the Dia skylights) and of their formal relation to the rooms that contain them. There’s no savoring of style, just stark presentation. His work’s economy and quietness may be pleasing, but its chief attraction is philosophical. What is a painting? Are there values inherent in the medium’s fundamental givens — paint skin, support surface, wall — when they are denied traditional decorative and illustrative functions? Such questions absorb Ryman. Do they excite you? Your answer might betray how old you are.

And Ryman himself talked about why he uses white in an interview with Art21:

White has a tendency to make things visible. With white, you can see more of a nuance; you can see more. I’ve said before that, if you spill coffee on a white shirt, you can see the coffee very clearly. If you spill it on a dark shirt, you don’t see it as well. So, it wasn’t a matter of white, the color. I was not really interested in that. I started to cover up colors with white in the 1950s. It has only been recently, in 2004, that I did a series of white paintings in which I was actually painting the color white. Before that, I’d never really thought of white as being a color, in that sense.


The Westworld season two soundtrack covers Kanye & Nirvana

One of my favorite aspects of HBO’s Westworld is the music, particularly the acoustic covers of modern rock and pop songs, many of which sound like they could be coming from a player piano in the show’s Old West saloon. The first season’s soundtrack, composed by Ramin Djawadi, featured covers of songs by Radiohead, Amy Winehouse, and the Rolling Stones. The second season is starting in just a couple of weeks, but they’ve already released two new covers from this season’s soundtrack: Heart-Shaped Box by Nirvana and Kanye West’s Runaway.

Djawadi, perhaps best known as the composer of the Game of Thrones theme song, spoke to Pitchfork about the rationale behind the cover songs:

What I love about that is it just comes out of nowhere and you don’t expect it at all. You see the settings and the way people are dressed and even though you know it’s robots and it’s all made to be modern entertainment, you would think the people in control would make everything authentic, including whatever is played on that player piano. It would be from that time period. And when it’s not, it’s that subtle reminder that, ‘Wait, there is something not right. This is not real.’ It’s just such a powerful tool that only music can do.


Trailers for Wall-E in the style of seven different genres (horror, romance, etc.)

Recutting movie trailers to wrong-foot movies into different genres is an old YouTube tradition — see The Shining as a romantic comedy, 90s-style opening credit sequences for prestige dramas like Game of Thrones, and Toy Story as a horror film — but this recasting of Wall-E into trailers for seven different genres (including a Jony Ive bit at an Apple keynote) is a good demonstration of the power of film editing. Just switch a few scenes, slip in some different music, change the pacing of cuts, and you’ve got yourself a completely different movie. Watching these types of videos always makes me think that film editors do not get the credit they deserve. (See, for example, how extensive editing rescued Star Wars.) (via @johnbarta)


Hoshi Ryokan, One of the World’s Oldest Hotels

From visual journalist Fritz Schumann, a short, poignant documentary on Hoshi Ryokan, a Japanese hotel built on a hot springs that has been run by the same family for 1300 years, making it the oldest running family business in the world.

This ryokan (a traditional japanese style hotel) was built over a natural hot spring in Awazu in central Japan in the year 718. Until 2011, it held the record for being the oldest hotel in the world.

Houshi Ryokan has been visited by the Japanese Imperial Family and countless great artists over the centuries. Its buildings were destroyed by natural disasters many times, but the family has always rebuilt. The garden as well as some parts of the hotel are over 400 years old.

The ryokan is now on its 46th generation of ownership. As you might expect, the changing role of the family in Japanese society has put the future succession of the hotel to the next generation in jeopardy. (via open culture)


An animated “music video” of similar satellite imagery

Arena is a video created by Páraic & Pearse McGloughlin constructed from different structural forms (roads, stadiums, center-pivot irrigation circles) in satellite images of the Earth animated together into a kind of music video. (It’s hard to describe it. Just watch and you’ll see what I mean.) The first part of the video, with the roads, reminded me of the screensaver on a computer or DVD player where a ball or logo bounces around the screen.

McGloughlin did an interview with Director’s Notes about how the video was produced.

I put a lot of focus on imagery containing flat lines, symmetry and grids as they are so different to the patterns/shapes made by nature, and hoped in turn that this would be most effective. It wasn’t until I started messing with some images that I thought to allocate the idea of the game of life — “Arena” to the theme as it fit perfectly in my opinion. I wanted to create a retro-like video game effect out of the images and I knew I wanted to start with flat roads ‘bouncing’ off the sides of the screen with an element of growth, a focus on the abundance of life on earth as well as some kind of evolution idea.

The World’s Largest Ice Carousel

Ice Carousel

Ice Carousel

Ice Carousel

A group of Mainers have created what they say is the world’s largest ice carousel. An ice carousel is formed when a circular piece of ice is allowed to spin freely within a surrounding sheet of ice. Spinning disks of ice can form naturally in slowly flowing rivers, but the ice carousel in Sinclair at the tip of northern Maine was cut specifically out of the ice on Long Lake.

The carousel is 427 feet across, a quarter mile in circumference, more than two feet thick, and estimated to weigh 11,000 tons. The keep the carousel spinning very slowly with a collection of outboard boat motors fastened to the disk. Here’s a video tour by drone:

The photos above are by Paul Cyr, who has many more here, including some of the construction process.


The full spoilers for season two of Westworld

Lisa Joy and Jonathan Nolan are the creators and producers of HBO’s Westworld. Last night, they released a 25-minute-long video on YouTube that they say contains the full spoilers for season two of the show. (Update: it’s a rickroll. Har har.)

Nolan shared the rationale for the unusual move on Reddit (which I’ve read three times and still don’t understand from a logic perspective):

I greatly enjoyed watching the friendly folks at this subreddit guess the twists and turns of the season.

It creates a larger problem for us, though, in terms of the way your guesswork is reported online. ‘Theories’ can actually be spoilers, and the line between the two is confusing. It’s something we’ve been thinking about since last season. The fans of Game of Thrones, for instance, rallied around and protected the secrets of the narrative in part because they already knew those secrets (through season 5).

We thought about this long and hard, and came to a difficult (and potentially highly controversial) decision. If you guys agree, we’re going to post a video that lays out the plot (and twists and turns) of season 2. Everything. The whole sordid thing. Up front. That way the members of the community here who want the season spoiled for them can watch ahead, and then protect the rest of the community, and help to distinguish between what’s ‘theory’ and what’s spoiler.

I have not watched it and won’t1 but from the comments in the thread (spoilers!), it appears legit. Orrrrr, it’s some elaborate troll by Nolan et al. to flood the zone with fake spoilers, to misdirect hardcore fans. Or maybe since Westworld contains many levels of fakes and artifice, I wonder if they’re doing this as part of an ARG, creating another layer of trickery and misdirection for the show? I guess we’ll see!

Update: LOL, I have been duped. SPOILERS: that video is mostly of a dog in front of a piano with the Westworld theme playing. And an olde tyme rendition of Never Gonna Give You Up. Hanging my head in deep shame.

I still believe that it would be cool if the show could somehow work in a release of faux spoilers into the main plot of the show. That would be impressive, more so than another rickroll.

  1. I am not a personal fan of spoilers; I prefer to watch/read/listen to things with as little foreknowledge as possible. But I also feel that good literature and films and TV shows are mostly unspoilable. If the plot is the only thing your book or movie has going for it, it’s probably not very good in the first place. Knowing what Rosebud is or the endings of various Hitchcock thrillers does not take anything away from the mastery of Citizen Kane, Vertigo, or Rear Window.


A high-resolution tour of the Moon from NASA

Using imagery and data that the Lunar Reconnaissance Orbiter spacecraft has collected since 2009, NASA made this video tour of the Moon in 4K resolution. This looked incredible on my iMac screen.

As the visualization moves around the near side, far side, north and south poles, we highlight interesting features, sites, and information gathered on the lunar terrain.

Black Panther’s T’Challa competes on SNL’s Black Jeopardy

Chadwick Boseman, who portrays T’Challa in Black Panther, hosted Saturday Night Live over the weekend, appearing in character on Black Jeopardy. Let’s just say T’Challa finds it challenging to understand the cultural references and idioms of contemporary American Black English but eventually gets the hang of it. I laughed solidly, and at times uncomfortably, through the entire thing.

See also Tom Hanks’ appearance on Black Jeopardy, which Jamelle Bouie highlighted as a particularly astute piece of American political analysis.

Lessons from the Screenplay: the influences and cleverness of Black Mirror

In this video, Lessons from the Screenplay examines what makes one of the best episodes of Black Mirror, USS Callister, so effective and entertaining.

The USS Callister episode of Black Mirror is a bit of an anomaly amongst the nineteen episodes of the series. It cleverly introduces the antagonist in an unconventional way, brings the premise of an old Twilight Zone episode into the near future, and manages to constantly be doing multiple things at once.

His second example of how the show does multiple things at once, which occurs right at the end of the episode, is excellent.


Carl Sagan’s tools for critical thinking and detecting bullshit

In his 1995 book The Demon-Haunted World, astrophysicist Carl Sagan presented a partial list of “tools for skeptical thinking” which can be used to construct & understand reasoned arguments and reject fraudulent ones.

Wherever possible there must be independent confirmation of the “facts.”

Encourage substantive debate on the evidence by knowledgeable proponents of all points of view.

Arguments from authority carry little weight — “authorities” have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.

Spin more than one hypothesis. If there’s something to be explained, think of all the different ways in which it could be explained. Then think of tests by which you might systematically disprove each of the alternatives. What survives, the hypothesis that resists disproof in this Darwinian selection among “multiple working hypotheses,” has a much better chance of being the right answer than if you had simply run with the first idea that caught your fancy.

Try not to get overly attached to a hypothesis just because it’s yours. It’s only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives. See if you can find reasons for rejecting it. If you don’t, others will.

Quantify. If whatever it is you’re explaining has some measure, some numerical quantity attached to it, you’ll be much better able to discriminate among competing hypotheses. What is vague and qualitative is open to many explanations. Of course there are truths to be sought in the many qualitative issues we are obliged to confront, but finding them is more challenging.

If there’s a chain of argument, every link in the chain must work (including the premise) — not just most of them.

Occam’s Razor. This convenient rule-of-thumb urges us when faced with two hypotheses that explain the data equally well to choose the simpler.

Always ask whether the hypothesis can be, at least in principle, falsified. Propositions that are untestable, unfalsifiable are not worth much. Consider the grand idea that our Universe and everything in it is just an elementary particle — an electron, say — in a much bigger Cosmos. But if we can never acquire information from outside our Universe, is not the idea incapable of disproof? You must be able to check assertions out. Inveterate skeptics must be given the chance to follow your reasoning, to duplicate your experiments and see if they get the same result.

I found this via Open Culture, which remarked on Sagan’s prescient remarks about people being “unable to distinguish between what feels good and what’s true”.

Like many a science communicator after him, Sagan was very much concerned with the influence of superstitious religious beliefs. He also foresaw a time in the near future much like our own. Elsewhere in The Demon-Haunted World, Sagan writes of “America in my children’s or grandchildren’s time…. when awesome technological powers are in the hands of a very few.” The loss of control over media and education renders people “unable to distinguish between what feels good and what’s true.”

This state involves, he says a “slide… back into superstition” of the religious variety and also a general “celebration of ignorance,” such that well-supported scientific theories carry the same weight or less than explanations made up on the spot by authorities whom people have lost the ability to “knowledgeably question.”

Yeeeeeeeep.

Update: After I posted this, a reader let me know that Michael Shermer has been accused by several women of sexually inappropriate & predatory behavior and rape at professional conferences. I personally believe women, and I further believe that if Shermer was actually serious about rationality and his ten rules for critical thinking listed above, he wouldn’t have pulled this shit in the first place (nor tried to hamfistedly explain it away). I’ve rewritten the post to remove the references to Shermer, which actually made it more succinct and put the focus fully on Sagan, which was my intention in the first place (the title remains unchanged).

Poetry in America series on PBS

Poetry in America is an upcoming 12-part series exploring poetry on a variety of topics. Each episode features the discussion of a single poem — “I cannot dance upon my toes” by Emily Dickinson, “Skyscraper” by Carl Sandburg, “N.Y. State of Mind” by Nas — with a collection of notable people — Samantha Power, Shaquille O’Neal, E.O. Wilson, Yo Yo Ma, Bill Clinton. The first episode airs this week but is already available on Amazon.


A comparison of the sizes of various microorganisms, cells, and viruses

Microorganisms are so small compared to humans that you might be tempted to think that they’re all about the same size. As this video shows, that is not at all the case. The rinovirus and polio virus are 0.03 micrometers (μm) wide, a red blood cell is 8 μm, a neuron 100 μm, and a frog’s egg 1 mm. That’s a span of 5 orders of magnitude, about the same difference as the height of a human to the thickness of the Earth’s atmosphere.

Watching the animation, you might have noticed the T4 bacteriophage, which looks like a cross between the aliens in Arrival and a lunar lander. Can’t be real, right? Bacteriophages are really real and terrifying…if you happen to be a bacteria. Bacteriophages attack by attaching themselves to bacteria, piercing their outer membranes, and then pumping them full of bacteriophage DNA. The phage replicates inside of the bacteria until the bacteria bursts and little baby bacteriophages are exploded out all over the place, ready to attack their own bacteria.


Rams, a documentary about legendary designer Dieter Rams

Dieter Rams is one of the world’s most influential designers. Rams acolyte and Apple design chief Jony Ive has said of him:

Dieter Rams’ ability to bring form to a product so that it clearly, concisely and immediately communicates its meaning is remarkable… He remains utterly alone in producing a body of work so consistently beautiful, so right, and so accessible.

Gary Hustwit, director of Helvetica and Objectified, is making a documentary about Rams called Rams. Here are three short clips from the film:

Rams will include in-depth conversations with Dieter, and dive deep into his philosophy, his process, and his inspirations. But one of the most interesting parts of Dieter’s story is that he now looks back on his career with some regret. “If I had to do it over again, I would not want to be a designer,” he’s said. “There are too many unnecessary products in this world.” Dieter has long been an advocate for the ideas of environmental consciousness and long-lasting products. He’s dismayed by today’s unsustainable world of over-consumption, where “design” has been reduced to a meaningless marketing buzzword.

The movie will have original music by Brian Eno and will be released sometime later this year.

Update: Wallpaper has a trailer for the film, which looks minimalistic af.


Hear Beowulf & Sir Gawain and the Green Knight read in the original Old and Middle English

In this short video, MIT literature professor Arthur Bahr reads brief selections from Beowulf and Sir Gawain and the Green Knight in their original languages, respectively Old English and Middle English. You’ll notice that they sound almost completely like foreign languages. From Open Culture:

After the Viking and Norman invasions, Old English became “the third language in its own country,” notes Luke Mastin at his History of English site. More spoken than written, it “effectively sank to the level of a patois or creole,” with several distinct regional variants. English seemed at one time “in dire peril” of dying out but “showed its resilience once again, and, two hundred years after the Norman Conquest, it was English not French that emerged as the language of England,” though it remained a diffuse collection of dialects.

The entire page on Middle English at the History of English site — “how English went from an obscure German dialect to a global language” — is worth a read.

Meet Doris Jones, a 90-year-old armchair space archaeologist

I don’t know who my old favorite archaeologist was, but my new favorite archaeologist is Doris Jones. Jones is 90 years old and is one of the top volunteer space archaeologists on GlobalXplorer, a site that crowdsources the process of locating potential archaeological sites on satellite imagery. People like Jones look at satellite images for telltale signs of past human activity and promising locations are then passed on to field archaeologists working in the area.


Fooling online users with dark patterns

From Evan Puschak, a quick video on dark patterns, UI design that tricks users into doing things they might not want to do. For instance, as he shows in the video, the hoops you need to jump through to delete your Amazon account are astounding; it’s buried levels deep in a place no one would ever think to look. This dark pattern is called a roach motel — users check in but they don’t check out. I wonder how much this single pattern has added to Jeff Bezos’ personal net worth?


The world’s smallest sushi is made from a single grain of rice

Tiny Sushi

At Sushiya no Nohachi in Tokyo, you can eat sushi that is made using a single grain of rice. The tiny sushi came about when a customer challenged the owner’s son to make the smallest possible sushi.

The most difficult tiny sushi are the ones with nori seaweed — those are the sea urchin and egg. For sea urchin, he has to put a small piece of nori around a grain of rice horizontally. For egg, he has to wrap the nori around the egg and grain of rice. It’s pretty impressive to witness.

You can see the small sushi being made in this video:

That said, when we asked how often they need to make a plate of small sushi, we were surprised.

“Just a few times a week and at most five times in a day.” Though when customers from overseas order, they tend to be extra enthusiastic about the tiny sushi.

He told us that one woman from Europe burst into tears and cried for an hour and a half after seeing the cute, little sushi.

How to Make 29 Different Shapes of Pasta by Hand

Somehow, I happily watched all 26 minutes of this video on how to make 29 different pasta shapes by hand. Pasta architecture is fascinating!

Semolina pasta is a southern Italy specialty. From that dough, Luca makes cavatelli, malloreddus, lorighittas, cencioni, capunti, strascinati, culurgionis, and sagne incannulate. From the egg dough, D’Onofrio makes fusilli al ferretto, tagliatelle, tortellini, farfalle, garganelli, anolini, cappelletti, tagliolini, agnolotti, sacchetti. From the spinach dough, Luca makes foglie d’ulivo, trofie, fagiolini, and pappardelle. From the cuttlefish squid ink pasta dough, D’Onofrio makes orecchiette, strichetti, fettuccine, and corzetti.

The Preciousness of Time, a tribute to Stephen Hawking

John Boswell, aka melodysheep, created this tribute video for Stephen Hawking using the late physicist’s words drawn from a variety of different speeches and interviews. It begins:

I am very aware of the preciousness of time. I was given two to three years to live. I faced a life unable to properly communicate. Fortunately my mind was unaffected. While all around me people have passed the day deep in conversation, I have often been transported afar, lost inside my own thoughts, trying to fathom how the universe works.
