The Mechanically Separated Meat blog has created a merged video of hundreds of games played against "Kaizo Mario World" (an insanely difficult homebrew Mario level) and used the resulting video as the jumping-off point for an extremely stimulating and enlightening discussion of the Many Worlds hypothesis in quantum physics. If I had to explain Many Worlds to an eight-year-old (something I expect to have to do in, oh, about eight years), this is where I'd start. I'm especially enamored of the choice of Mario for this, since it's just the right blend of puzzler and jumper to make you want
to explore all possible choices (I've recently become brutally addicted to Paper Mario
, which now occupies about 10 percent of my brain on a more-or-less permanent basis as a kind of low-grade background process).
This said, tiny quantum events can create ripples that have big effects on non-quantum systems. One good example of this is the Quantum Suicide “experiment” that some proponents of the Many-Worlds Interpretation claim (I think jokingly) could actually be used to test the MWI. The way it works is, you basically run the Schrödinger’s Cat thought experiment on yourself– you set up an apparatus whereby an atom has a 50% chance of decaying each second, and there’s a detector which waits for the atom to decay. When the detector goes off, it triggers a gun, which shoots you in the head and kills you. So all you have to do is set up this experiment, and sit in front of it for awhile. If after sixty seconds you find you are still alive, then the many-worlds interpretation is true, because there is only about a one in 1018 chance of surviving in front of the Quantum Suicide machine for a full minute, so the only plausible explanation for your survival is that the MWI is true and you just happen to be the one universe where the atom’s 50% chance of decay turned up “no” sixty times in a row. Now, given, in order to do this, you had to create about 1018 universes where the Quantum Suicide machine did kill you, or copies of you, and your one surviving consciousness doesn’t have any way of telling the people in the other 1018 universes that you survived and MWI is true. This is, of course, roughly as silly as the thing about there being a universe where all the atoms in your heart randomly decided to tunnel out of your body.
But, we can kind of think of the multi-playthrough Kaizo Mario World video as a silly, sci-fi style demonstration of the Quantum Suicide experiment. At each moment of the playthrough there’s a lot of different things Mario could have done, and almost all of them lead to horrible death. The anthropic principle, in the form of the emulator’s save/restore feature, postselects for the possibilities where Mario actually survives and ensures that although a lot of possible paths have to get discarded, the camera remains fixed on the one path where after one minute and fifty-six seconds some observer still exists.
Apple released this lovely new commercial featuring Carl Sagan reading from his magnificent 1994 book Pale Blue Dot: A Vision of the Human Future in Space, now available as an audiobook. This surprising partnership spurred Adweek to interview my friend Ann Druyan, Sagan’s wife, collaborator, and creative director of the Voyager Golden Record, about being […]
The Action Lab took a maglev gyroscope and placed it inside a sealed chamber to see what happens to a levitating gyroscope in a vacuum. A lot of people took issue with the experiment’s setup and explanation, but it’s interesting nonetheless. He responded to those concerns: Hi everyone! I see a lot of comments that […]

Although flagship smartphones are unlikely to adopt heavy-duty outer casing anytime soon, you can always prepare your device for the outdoors with a beefy case and and an external battery like this Nomad Tile Trackable PowerPack, available in the Boing Boing Store for $119.95.The Nomad Tile can fully recharge an iPhone 7 over three times […]
Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
