Is it possible to extinguish the Sun with water?DEC 12

From Quora, an answer to the question "If we pour water on the sun with a bucket as big as the sun, will the sun be extinguished?"

The probable answer is "no." The Sun involves a special type of fire that is able to "burn" water, and so it will just get hotter, and six times brighter.

Water is 89% oxygen BY MASS. And the Sun's overall density is 1.4 times that of water. So if you have a volume of water the VOLUME of the Sun, it will have 1/1.4 = 0.71 times the mass of the Sun, and this mass will be .71*.89 = 63% of a solar mass of oxygen and 8% of a solar mass of hydrogen. The Sun itself is 0.74 solar masses of hydrogen and 0.24 solar masses of helium.

So you end up with a 1.7 solar mass star with composition 48% hydrogen, 37% oxygen, and 14% helium (with 1% heavier elements).

Now, will such a star burn? Yes, but not with the type of proton-proton fusion the Sun uses. A star 1.7 times the mass of the Sun will heat up and burn almost entirely by the CNO fusion cycle, after making some carbon and nitrogen to go along with all the oxygen you've started with. So with CNO fusion and that mass you get a type F0 star with about 1.3 times the radius and 6 times the luminosity of the present Sun, and a temperature somewhat hotter than the Sun (7200 K vs. the Sun's 5800 K). It will be bluish-white, with more UV. That, along with that 6 times heat input, will cause the Earth's biosphere to be fried, and oceans to probably boil.

Well, we probably shouldn't do that then. (via gizmodo)

More StormscapesDEC 11

This time lapse video of storm clouds by Nicolaus Wegner is flat-out incredible, by far the best of its kind.

Crank up the sound for this one. Previously: Stormscapes 1. (via bad astronomy)

Welcome to Union GlacierDEC 11

While working as a filmmaker as part of the Scott Expedition, Temujin Doran made a beautifully shot and edited short film about a small team of people who live and work on Antarctica's Union Glacier during the summer.

For me, this film seems a bit like an antithesis to many expedition and adventure documentaries. There is no great achievement or record broken, nor any real challenge to overcome. Instead it concerns minor details; the everyday tasks of the staff that were made more special by the environment surrounding them. And in fact, I think that's what attracted me to make this film - the delightful trivialities of an average life, working in Antarctica.

Wes Anderson-esque. (thx, joseph)

The 2014 kottke.org Holiday Gift GuideDEC 11

Last year, I did a meta holiday gift guide where I picked some of the best items off of the best gift guides out there. Since we're getting down to the wire here on shopping time (not that you should buy anything for anyone this holiday season or any other time of the year), let's crank up this year's version.

Consider giving to charity this year. If you can't spare the time to volunteer (look here or Google for specific opportunities in your area), go on Charity Navigator or Give Well to find an organization worth your attention. Or go on Kiva and give small loans to dozens of families around the world.

For their list this year, The Wirecutter did a list of The Things We Want to Give. Items include The Neat Ice Kit, Benton's ham, and The Flavor Thesaurus. Hmm, I picked all food stuff there. I must be hungry.

I recommend these every year: the Tovolo King Cube Ice Tray and the KitchenAid Professional 600 Series 6-Quart Stand Mixer.

From Boing Boing's Happy Mutant's Gift Guide 2014, the excellent Eyes on the Prize documentary on DVD, the LifeSpan TR1200-DT5 Treadmill Desk, a Lodge 10.5-inch round skillet (can personally vouch for this), and perhaps my favorite Amazon item of all time, the 55-gallon drum of personal lubricant. Don't worry, the latter item includes a lube pump so you don't need to buy it separately.

For the sports fan in your life, SB Nation's 2014 Holiday Gift Guide includes Zubaz pants (!!), Big League Chew, the Bluetooth Gramophone, and a home beer brewing kit. Throwback-errific!

Among the items on the Tools & Toys Christmas Catalog, Bartlett's Familiar Quotations and the Bellroy Slim Sleeve Wallet (which is my own personal wallet).

Nothing on Mat Honan's 8 Perfect Gift Ideas for 'Twitter Dads' really grabbed me (even though I am an official Twitter Dad), except for the Bugaboo Bee. We had the first iteration of that stroller and it was the absolute best thing. We wore out two sets of wheels strollering Ollie and Minna around the city in that thing.

But I'll take one of everything off of The Kid Should See This Gift Guide. Especially Animalium, the Crosley portable turntable, My Neighbor Totoro on Blu-ray, and a vintage typewriter. [Update: My friend Dan says to avoid Crosley turntables: "They use ceramic cartridges that track 3x as heavy as standard carts, permanently damaging records." I have no idea what that means, but Dan knows things about turntables so you might want to make another choice.]

Good year for science-ish nonfiction books: How We Got to Now by Steven Johnson, What If? by Randall Munroe, Being Mortal by Atul Gawande, Superintelligence by Nick Bostrom, and Creativity, Inc. by Ed Catmull.

And cookbooks: Plenty More from Yotam Ottolenghi, MEAT by Pat LaFrieda, Tartine Bread by Chad Robertson, Michael Ruhlman's Egg, Death & Co: Modern Classic Cocktails, My Paris Kitchen from David Lebovitz (whose Paris dining recommendations are top notch), and Jeffrey Morgenthaler's The Bar Book.

The Brooklyn Holiday Gift Guide features products made locally in Brooklyn, including bracelets with subways maps and kottke.org favorite, Tattly.

Tom Bihn's What We're Giving list includes Fairbault wool blankets and their own Shop Bag. (via @widepipe)

One of many holiday lists from Food52, the Under $25 Gift Guide features Heirloom Seed Art Packets and this Water Bottle with Charcoal Filter.

The Continuous Lean went on a serious listing bender with The Epic ACL Holiday Gift Guide 2014. The stylish selections include the Whiskey Wedge, the Jaguar F-Type Project 7, and the Lego Architecture Fallingwater set.

Josh Rives made a list of gifts that don't suck. Among the non-suckage is The Dangerous Book for Boys, Coudal and Draplin's excellent Field Notes, and Cards Against Humanity.

Many many things on the NY Times Holiday Gift Guide, including Julia, Child these awesome cement stair planters, and History of the World in 1,000 Objects.

Since their acquisition by Vox, Eater has been better than ever. Their Holiday Gift Ideas 2014 package is overflowing with good choices, among them are sausages from Butcher & the Boar (smoooooked cheddarwurst!!!) and Fictitious Dishes.

Speaking of Vox, The Verge has a load of tech-oriented picks, including a selection under . They recommend MUJI notebooks and David Mitchell's The Bone Clocks. One of The Verge's more baller picks is the Nintendo Wii U Mario Kart 8 Deluxe Set. Which, droooooool. Santa, you got me covered on this?

Misc: the Good Web Bundle gives you subscriptions to five indie services/sites for one low price. You can get 8GB flash drives in necklace form now. From Haruki Murakami, a recently released short novel about "a boy imprisoned in a nightmarish library". I have no idea if they are actually vintage or just made to look so, but you can find several vintage Soviet chess sets on Etsy (like this one); I bought one recently and if someone faked it, they did a good job. (Even if it's fake, it's real, etc.) You can buy Post-It Notes that are almost two-feet across.

Update: Added the guide from Tools & Toys and added a warning about the portable turntable. Added giant Post-It Notes. Added The Brooklyn Holiday Gift Guide. Added Tom Bihn's list. Added Food52 list. Added The Continuous Lean set. Added a list of gifts that don't suck. Added lists from the NY Times, Eater, and The Verge.

Curiosity: stronger support for life on MarsDEC 11

Whilst roving about Mars, Curiosity has slowly but surely racked up evidence for a past Mars that was warm, wet, and possibly habitable.

John P. Grotzinger of Caltech, the project scientist for the mission, reported at a news conference on Monday that the rover's yearlong trek to Mount Sharp provided strong new evidence that Gale Crater had large lakes, rivers and deltas, on and off, for millions to tens of millions of years. The geology shows that even when the surface water dried up, plenty of water would have remained underground, he said.

Moreover, the team concluded, numerous deltalike and lakelike formations detected by orbiting satellites are almost certainly the dried remains of substantial ancient lakes and deltas. None of this proves that life existed on the planet, but the case for an early Mars that was ripe and ready for life has grown stronger.

"As a science team, Mars is looking very attractive to us as a habitable planet," Dr. Grotzinger said in an interview. "Not just sections of Gale Crater and not just a handful of locations, but at different times around the globe."

See also the interactive 28 Months on Mars.

Update: And right on cue, Curiosity has recorded a two-month-long methane burst on Mars. One explanation for the methane is that it's a waste product of living organisms.

The presence of methane is significant because the gas cannot exist for long. Calculations indicate that sunlight and chemical reactions in the Martian atmosphere would break up the molecules within a few hundred years, so any methane there now must have been created recently.

It could have been created by a geological process known as serpentinization, which requires both heat and liquid water. Or it could be a product of life in the form of microbes known as methanogens, which release methane as a waste product.

Even if the explanation for the methane turns out to be geological, the hydrothermal systems would still be prime locations to search for signs of life.

Recursive gamingDEC 11

The Entire Screen of One Game is like the video game version of Powers of Ten. The game isn't fun or winnable, but it will confuse your brain after only a few seconds. (via @pieratt)

Inside the brain of a designerDEC 10

If you've ever wondered how a designer does their thing (or even if you haven't), this look-over-the-shoulder view of Aaron Draplin designing a logo for a fictional company in about 10 minutes is great. A nice reminder that design is truly about making it up as you go along.

I love Draplin. Internet treasure, that guy. And that lefty writing claw! Go lefties!

An oral history of Boogie NightsDEC 10

Every once in awhile on the site, I'll use the phrase "in my wheelhouse", meaning something that is particularly interesting to me. Well, Grantland's long oral history of the making of Boogie Nights is so in my wheelhouse that I might be the captain.

When [Anderson] set out to film Boogie Nights, it was with a resolve bordering on arrogance. Compromise wasn't part of the plan. Still, after an intense production and postproduction period -- one in which the director had to manage a cranky, confused Burt Reynolds and an untested, rapping underwear model named Mark Wahlberg -- Anderson was forced once again to fight studio heads for his cut of the film.

But Anderson's vision prevailed this time. Nearly 20 years later, Boogie Nights endures. For its beautiful portrait of nontraditional families; for Reynolds and Wahlberg, the surrogate father and son, who were never better; for Philip Seymour Hoffman, squeezing into character and breaking hearts; for its prodigy director sticking to his guns and nailing it; for John C. Reilly's hot-tub poetry; for Roller Girl. Is everybody ready? This is the making and near unmaking of Boogie Nights.

Man, I love that movie. But think on this: Leonardo DiCaprio as Dirk Diggler, Drew Barrymore as Roller Girl, and Bill Murray as Jack Horner.

Marbled paper, what a curious nameDEC 10

Wow, the art of making marbled paper, a short film from 1970.

Charmingly British, just like the film about the Teddy Grays candy factory or the putter togetherer of scissors. Super cool how the inks are placed on a water bath, swirled expertly to make patterns, and then transferred to the paper. Also of note: the segment on the conservation of old books starting at around 9:55...I never knew they took them apart like that to dunk the pages in water! Sadly, the Cockerell Bindery ceased operation in the late 1980s with the death of Sydney Cockerell and its contents were sold at auction. (thx, matt)

The Senate report on the CIA's torture practicesDEC 09

This is disgusting and awful and monstrous and I don't even know what to say about it. The NY Times lists seven key points (full article) from a report released by the Senate Select Committee on Intelligence about the CIA's torture practices. We knew it was bad, suspected it was worse, but this is just beyond.

The report describes extensive waterboarding as a "series of near drownings" and suggests that more prisoners were subjected to waterboarding than the three prisoners the C.I.A. has acknowledged in the past. The report also describes detainees being subjected to sleep deprivation for up to a week, medically unnecessary "rectal feeding" and death threats. Conditions at one prison, described by a clandestine officer as a "dungeon," were blamed for the death of a detainee, and the harsh techniques were described as leading to "psychological and behavioral issues, including hallucinations, paranoia, insomnia, and attempts at self-harm and self-mutilation."

This is surely the shit sandwich on top of an already unbearable year. I agree wholeheartedly with Vermont Senator Bernie Sanders, who issued this statement about the report:

A great nation must be prepared to acknowledge its errors. This report details an ugly chapter in American history during which our leaders and the intelligence community dishonored our nation's proud traditions. Of course we must aggressively pursue international terrorists who would do us harm, but we must do so in a way that is consistent with the basic respect for human rights which makes us proud to be Americans.

"The United States must not engage in torture. If we do, in an increasingly brutal world we lose our moral standing to condemn other nations or groups that engage in uncivilized behavior.

YouTube goes proDEC 09

There's a good reason your cat looks so depressed. The days of her antics dominating YouTube are long gone. As the New Yorker's Tad Friend explains, in addition to cats "YouTube was adults with camcorders shooting kids being adorably themselves. It was amateur hour." Since then, YouTube has gone pro. Jeffrey Katzenberg predicts that "within five years, YouTube will be the biggest media platform of any, by far, in the entire world." It's where your kids are. It's where the new stars are. And it's where your cat isn't. Welcome to the new Hollywood and Vine.

The skiing line of the yearDEC 09

This is the craziest thing I've ever seen anyone do on skis: Cody Townsend skiing down a super steep face in a space between two rock walls no wider than a supermarket aisle. Powder Magazine called it "The Line of the Year".

They forgot to put "Batshit Crazy" before the word "Line". (via devour)

The 40 most groundbreaking albums of all timeDEC 09

Rolling Stone lists the 40 most groundbreaking music albums in history. Kanye West makes the list with 808s and Heartbreaks, Dr. Dre with The Chronic, Nirvana with Nevermind, and the Beatles with Rubber Soul and Sgt. Pepper's. About The Chronic:

The album sold a world to white America that it had never really seen before, and packaged it with a soundtrack so funky there was no avoiding it. It was both raw, uncut underground and carefully composed pop. If Public Enemy confronted white America, The Chronic seduced it. For the first time ever, hip-hop's mainstream and America's were one.

I counted only four women artists though: Mary J. Blige, Loretta Lynn, Nico, and Carole King.
