"The most notable “discovery” in the dataset was that if you simply plotted the number of steps versus the BMI, you would see an image of a gorilla waving at you (Fig. 1b). While we teach our students the benefits of visualization, answering the specific hypothesis-driven questions did not require plotting the data. We found that very often, the students driven by specific hypotheses skipped this simple step towards a broader exploration of the data. In fact, overall, students without a specific hypothesis were almost five times more likely to discover the gorilla when analyzing this dataset (odds ratio = 4.8, P = 0.034, N = 33, Fisher’s exact test; Fig. 1c). At least in this setting, the hypothesis indeed turned out to be a significant liability."

Highly valuable for all affected, and yet still completely absurd to think about. Technology Is People (and is also a complete nuisance).

Notes on the passing of John Conway, but also, a delightful set of comments sharing first-hand memories of Conway – particularly being taught by him – that bring him to life.

"One way to illustrate that most technologies are, in fact, pretty "hi," is to ask yourself of any manmade object, Do I know how to make one?

Anybody who ever lighted a fire without matches has probably gained some proper respect for "low" or "primitive" or "simple" technologies; anybody who ever lighted a fire with matches should have the wits to respect that notable hi-tech invention." Ursula le Guin with strong truth about technology and science fiction.

Stephen Wolfram on "designing science" for Arrival. I always forget the Wolfram Language is real; it looks like movie-computer, but is in fact real-computer. Lots of nice points in here – especially about going from the scientific reasoning back to things that work in a two-hour movie.

"I don't usually do in-depth analyses of my bots, especially one that's probably not gonna break ten followers, but my most recent bot is very personal to me, and the making of it turned out to be much stranger than I expected. It's The Bot of Mormon, "the most correct bot", a text-generating process with a very niche audience but the niche audience includes me, so I'm happy." Great, detailed post from Leonard on making programattic jokes: his explanation of the ongoing struggle to make the bot entertaining is good, and the solution he comes to smart.

"A wood and brass sound synthesizer built by Max Kohl after the design by Hemholtz. 39½ x 29 inch mahogany base with turned feet, fitted with 11 small wooden platforms, each marked with a number and the words "aus" [from] and "ein" [to], 10 of the platforms fitted with tuning forks and accompanying brass Helmholtz resonators, the tallest measuring 18½ high, each pair ranging in size according to their graduating frequencies, 11th platform fitted with 1 large horizontal master tuning fork." Oh my.

"When I was a child in school, the fact that the laws of nature seemed to be permanent and immutable, compared to the laws of the state, made science most attractive to me. And I recall as a kid in school, a physics experiment—and my also mischievous pleasure that even these overwhelming, secular authorities couldn’t change the direction of a beam of electrons." And it goes from there. Ursula Franklin sounds quite remarkable.

More details on the reasons why elephants' brains are brilliant.

"You know, maybe aliens know all this, and we’re come-latelies to the whole comprehending-everything thing, but there isn’t really any more you can do in our current Universe than this. It’s the top thing. It is everything. This makes us amazing." James has basically said everything about our trip to CERN that is worth saying. This is all true. It was great and humbling. I'd also point out that every time you step out, you're under the Alps, and they're also phenomenal and humbling.

" For our project, we had to find three scenes from any movie or TV show and use physics to find out if something was or wasn't possible. I got 100% on it." In this case: 'Physical Impossibilities in My Little Pony: Friendship Is Magic'. He's really not wrong about the animation.

"I am currently using heart measurement equipment for an experiment as part of my PhD and for fun (N=1 isn't usually great Science) I thought I would bring the equipment home last weekend and see what my heart looks like when I am playing a mutliplayer game of Halo Reach (Slayer DMRs on Zealot – Blue Team). Here is what I found."

"Leave the libraries alone. You don’t know the value of what you’re looking after. It is too precious to destroy." I know that the rhetoric works better as a speech than in writing; still I can't help but agree with this. It tugs at things important to me, and what a small village public library meant for my childhood.
