Black Mirror season four

Six new episodes of Black Mirror are headed our way when the fourth season premieres later this year. There’s a short teaser trailer (above) and Netflix has also announced casts and directors for the season.

“Arkangel” stars Rosemarie Dewitt, Brenna Harding and Owen Teague. It is directed by Jodie Foster.

“Black Museum” stars Douglas Hodge, Letitia Wright and Babs Olusanmokun. It is directed by Colm McCarthy.

“Crocodile” stars Andrea Riseborough, Andrew Gower and Kiran Sonia Sawar. It is directed by John Hillcoat.


Last Flag Flying

Directed by Richard Linklater, Last Flag Flying tells the story of three army buddies (played by Bryan Cranston, Steve Carell, and Laurence Fishburne) who reunite when one of their sons is killed in combat. Judging from the trailer, this looks great, but what’s interesting is that this is a sequel of sorts to a Hal Ashby movie from more than 40 years ago.

Last Flag Flying is a sequel to Hal Ashby’s The Last Detail, which arrived all the way back in 1973. Both movies are based on novels of the same name from Darryl Poniscan (he published Last Detail in 1970 and Last Flag in 2005), and both feature the same trio of characters. Last Flag Flying finds Steve Carell playing the role Randy Quaid filled in Ashby’s original, Cranston filling in for [Jack] Nicholson, and Fishburne stepping in for Otis Young.


Black holes could delete the Universe

In their latest video, Kurzgesagt takes a look at black holes, specifically how they deal with information. According to the currently accepted theories, one of the fundamental laws of the Universe is that information can never be lost, but black holes destroy information. This is the information paradox…so one or both of our theories must be wrong.

The paradox arose after Hawking showed, in 1974-1975, that black holes surrounded by quantum fields actually will radiate particles (“Hawking radiation”) and shrink in size (Figure 4), eventually evaporating completely. Compare with Figure 2, where the information about the two shells gets stuck inside the black hole. In Figure 4, the black hole is gone. Where did the information go? If it disappeared along with the black hole, that violates quantum theory.

Maybe the information came back out with the Hawking radiation? The problem is that the information in the black hole can’t get out. So the only way it can be in the Hawking radiation (naively) is if what is inside is copied. Having two copies of the information, one inside, one outside, also violates quantum theory.

So maybe black holes holographically encode their information on the surface?


A Blue Angels jet surprises a crowd with a low pass

Sunday at The Chicago Air and Water Show, a Blue Angels combat jet flew very low past an unsuspecting crowd and surprised the bejeezus out of some folks. It’s worth watching this video on a large screen multiple times while focusing on the reaction of a different person each time. You can see how low and fast the plane was flying from another angle. They also flew between the buildings downtown.


When behavioral economics meets a $700M Powerball jackpot

Business Insider went out onto the streets of NYC and tried to buy people’s just-purchased Powerball tickets ahead of the $700 million drawing. They did not get many takers, even when offering twice the price they paid (which meant they could just go and buy double the number of tickets and slash their odds of winning). The video says this is an example of regret avoidance.

A theory of investor behavior that attempts to explain why investors refuse to admit to themselves that they’ve made a poor investment decision so they don’t have to face the unpleasant feelings associated with that decision. Regret avoidance causes investors to not correct bad decisions, which can make those decisions worse. Regret avoidance is the result of cognitive dissonance.

As Alex Tabarrok notes, it’s also a demonstration of the endowment effect (Tabarrok: “these people are crazy!”).

In psychology and behavioral economics, the endowment effect…is the hypothesis that people ascribe more value to things merely because they own them. This is typically illustrated in two ways. In a valuation paradigm, people will tend to pay more to retain something they own than to obtain something they do not own โ€” even when there is no cause for attachment, or even if the item was only obtained minutes ago. In an exchange paradigm, people given a good are reluctant to trade it for another good of similar value. For example, participants first given a Swiss chocolate bar were generally unwilling to trade it for a coffee mug, whereas participants first given the coffee mug were generally unwilling to trade it for the chocolate bar.

One way to think about it is if you buy a lottery ticket for $5 and someone offers you $10 and you don’t take it, financially it’s like you’ve paid $10 for the ticket, an easily replaceable item with an average worth of about $2.50 (and more likely worth nothing). But no one should be buying tickets anyway because the lottery sucks.

What witnessing a total eclipse is like

In an essay from 1982 about her seeing a total solar eclipse in Washington (recently republished in this collection), Pulitzer Prize winner Annie Dillard puts into words what I only attempted to express in my eclipse experience.

I had seen a partial eclipse in 1970. A partial eclipse is very interesting. It bears almost no relation to a total eclipse. Seeing a partial eclipse bears the same relation to seeing a total eclipse as kissing a man does to marrying him, or as flying in an airplane does to falling out of an airplane. Although the one experience precedes the other, it in no way prepares you for it.

I heard lots of disappointment with the eclipse among friends and on social media. It was neat โ€” look, there’s a chunk out of the Sun โ€” but they thought it would be darker or that the air would get colder. But none of that stuff really happens unless you’re really close to totality…and then it goes completely dark and your brain turns inside out. Twitter user @hwoodscotty said:

Probably the coolest thing I’ve ever seen. Totality is so much different than even 99%. 10/10 Would recommend.

And @omanreagan:

Standing on a mountaintop for totality was crossing into another dimension, suddenly finding ourselves on another world. Amazing. Sparkling ring, sun fire ghostly streaming, darkest circle. I understand now why people chase the eclipse. Totality is unlike anything. Entire landscape shifted, valleys, hills, mountains painted in nightcolour and cold. Sparkling planets came out in a midnight sky.

But back to Dillard’s piece…this part, about the shadow rushing towards them, sounds amazing:

I have said that I heard screams. (I have since read that screaming, with hysteria, is a common reaction even to expected total eclipses.) People on all the hillsides, including, I think, myself, screamed when the black body of the moon detached from the sky and rolled over the sun. But something else was happening at that same instant, and it was this, I believe, which made us scream.

The second before the sun went out we saw a wall of dark shadow come speeding at us. We no sooner saw it than it was upon us, like thunder. It roared up the valley. It slammed our hill and knocked us out. It was the monstrous swift shadow cone of the moon. I have since read that this wave of shadow moves 1,800 miles an hour. Language can give no sense of this sort of speed โ€” 1,800 miles an hour. It was 195 miles wide. No end was in sight โ€” you saw only the edge. It rolled at you across the land at 1,800 miles an hour, hauling darkness like plague behind it. Seeing it, and knowing it was coming straight for you, was like feeling a slug of anesthetic shoot up your arm. If you think very fast, you may have time to think, “Soon it will hit my brain.” You can feel the deadness race up your arm; you can feel the appalling, inhuman speed of your own blood. We saw the wall of shadow coming, and screamed before it hit.

Next time, and there will definitely be a next time, I’m hoping to get up high somewhere so I can see the shadow and more of the 360-degree sunset. BRB, pricing plane tickets to Argentina

Update: Before the 2017 eclipse, Vox talked to some eclipse chasers about what it’s like to witness a total solar eclipse.

Joss Fong, who produced the video, shared the following on Twitter:

now that i’ve recovered from the drive, i can say that a lot of what these eclipse chasers told me makes sense now. agree completely that it’s something you have to see for yourself. what was different for me though is …. i got pretty sad. there’s a fine line between awe and grief. maybe in a different year it would have gone the other way, but tbh every exceptionally beautiful sunset makes me a tiny bit sad too. but this was sunset sadness times a thousand. absolutely punched by the impermanence. i hope i see it again and i hope you can see it too.

Update: From XKCD:

XKCD eclipse

I watched from a beautiful nature reserve in central Missouri, and it was โ€” without exaggeration โ€” the coolest thing I’ve ever seen.

This is NSFW and pretty funny. 3-Way (Not Calling) is a short film about one couple’s attempt to spice things up in the bedroom with another person and how it goes slightly wrong and also slightly right. (via film school rejects)


The untold story of the Mississippi Delta Chinese

As part of a video series on Chinese food in America, Al Jazeera profiles the small population of Chinese-American families that have lived in the Mississippi Delta for more than 100 years.

There’s a rather unknown community of Chinese-Americans who’ve lived in the Mississippi Delta for more than a hundred years. They played an important role in the segregated South in the middle of the 20th century. Join us as we get a taste of Southern Chinese food and learn about the unique history of the Delta Chinese.

Originally coming to the area to pick cotton, many of the Chinese immigrants opened up grocery stores, mostly in the black communities in which they lived. One family owned two stores across the street from each other in the days of segregation: one for serving white customers and the other for serving black customers.

And, oh man, that Southern Chinese food looks absolutely delicious. This NPR story, The Legacy Of The Mississippi Delta Chinese, contains a little more information on the food.

But let’s get back to dinner. As the group gets busy chopping and sauteing in the kitchen, Gilroy heads outside and starts tossing fried rice in a gigantic wok nestled into a super-hot, custom burner stand.

He tosses in some cubed ham: “This is what makes it Southern fried rice!” he says.

Before long, an impressive feast is laid out before us: beef with cauliflower. Whole fish garnished with fried ginger. Spare ribs with carrots and potatoes. Roast pork with a honey-hoisin glaze, and much more. The flavors of their youth.


Walter Cronkite reports on the 1979 solar eclipse

The last total solar eclipse in the US and Canada took place in February 1979. Here’s Walter Cronkite’s original report on the eclipse for the CBS Evening News. It features druids, a rooster that was supposed to sleep during the eclipse, and interviews with some people who were obviously tripping balls during the celestial event.
