What I'm Learning

It also has a lot of different kinds of stitches you can do that make different densities of fabric.

I was surprised that I’d never heard of it though. It’s older than knitting and crocheting and even though it’s been done all over the world it’s super relevant to Nordic culture and my grandmother and I are both into keeping in touch with our roots a bit so I’m surprised I’ve never heard of it.

It’s also a lot easier to freehand and adjust as you go than crochet or knitting and you mostly go by inches instead of rows and number of stitches so a large number of accessories like stitch markers or whatever isn’t really necessary.

The downside as a beginner is that undoing mistakes is more time consuming than with knitting or crochet. You’ve gotta like sew your mistakes out backwards. Disadvantages of making a really sturdy fabric I guess.

I like the feel of this bone needle though and don’t think I’ll be trying the wooden or metal ones.

Also I think I’m gonna have to get good at doing Russian joining if I decide to get good at nalbinding because I don’t have wool yarn and the ends won’t felt together if it’s not at least 50% wool. A small price to pay for using big bone needle though.

I was tickled to find this because I'd been looking at a lot of stuff made out of not-particularly-feltable animal hair and wondering how it worked, only to find that the answer was: there's no reason you have to connect the ends at all. You can just weave in a new tail of yarn and start where the old yarn left off, and since it won't unravel you don't have to do anything more than that.

because SURPRISE, there's no such thing as "plastic" either. every kind of wood is basically the same on a chemical level, but the only thing every plastic has in common is "some of its molecules are long" and that is NOT a quality that determines how things stick together.

I just ordered some stuff I hope will permanently stick a circuit board to a steel sheet and withstand temperatures up to 150 degrees. by the way circuit boards are made of epoxy-bound woven glass cloth which is cool as hell but what the fuck do you glue that with? can any of the 12 kinds of adhesives I currently own do that? no of course not. if I want to stick two pieces of acrylic together so hard they become watertight to a depth of 3000 metres I have some shit that does that, but it does literally nothing else.

She got the idea for the study while walking with her advisor at Stanford to discuss her thesis topic, and the paper she eventually published in the Journal of Experimental Psychology in 2014 is sharp enough that it should have ended the seated meeting on the day it came out.

She ran 4 experiments on 176 people. Same person tested twice. Once sitting, once walking. The creativity tasks were the standard ones psychologists have used for decades to measure how good a brain is at generating novel useful ideas.

81% of participants in the first experiment produced more creative ideas while walking than while sitting. In the second experiment, 88%. In the third, 100%. Every single person walked into a more creative version of themselves. On average, people generated 60% more novel useful ideas the moment their legs started moving.

The skeptical question is the obvious one. Maybe it was the fresh air. Maybe it was the scenery passing by. Maybe it was the change of environment doing the work, not the walking itself.

Oppezzo killed every one of those explanations with one experimental decision. She put people on a treadmill facing a blank wall. No scenery. No fresh air. No environmental change. Just legs moving in place while staring at white drywall. The 60% boost held.

Then she ran the experiment that closed the case completely. She took participants outside in two conditions. Half of them walked through a Stanford courtyard. The other half were pushed through the exact same courtyard in a wheelchair. Same outdoor stimulation. Same scenery passing at the same speed. The only difference was whether the legs were moving.

The walkers produced dramatically more novel high-quality ideas than the wheelchair group. The outdoors did almost nothing on its own. The walking did everything.

She also tested the opposite kind of thinking. Convergent thinking. The kind where there is one right answer and you have to narrow down to it. Word puzzles where 3 words share a hidden fourth word that connects them. The seated participants did slightly better on these. Walkers got slightly worse.

Walking is not a general intelligence enhancer. It does one specific thing. It opens up the divergent search inside your brain. The part that generates options. The part that produces unexpected connections. The part that takes a problem and finds five ways into it instead of one.

When you need to converge on the single right answer, sit down. When you need to find the answer in the first place, get up.

The mechanism is now well understood. Walking selectively activates what neuroscientists call the default mode network, the system inside your brain that runs when you are not consciously focused on anything. The DMN is where mind-wandering happens. Where memories cross-reference each other. Where ideas that have been sitting in separate folders inside your head finally bump into each other.

When you sit at a desk and force yourself to concentrate, you suppress the DMN. When you walk at a natural pace, the executive part of your brain gets just busy enough handling the walking that the DMN comes online and starts doing the work that focus was blocking.

The most useful finding in the entire paper is the one almost nobody quotes. The boost did not turn off the moment people stopped walking. Participants who walked first and then sat back down stayed elevated. Their next round of seated creativity work was still significantly better than people who had been sitting the whole time. The rest lingered for at least several minutes after the legs stopped moving.

You do not need to do creative work while walking. You need to walk before the creative work. The brain holds the state.

The works of the roots of the vines, of the trees, must be destroyed to keep up the price, and this is the saddest, bitterest thing of all. Carloads of oranges dumped on the ground. The people came for miles to take the fruit, but this could not be. How would they buy oranges at twenty cents a dozen if they could drive out and pick them up? And men with hoses squirt kerosene on the oranges, and they are angry at the crime, angry at the people who have come to take the fruit. A million people hungry, needing the fruit- and kerosene sprayed over the golden mountains. And the smell of rot fills the country.

Burn coffee for fuel in the ships. Burn corn to keep warm, it makes a hot fire. Dump potatoes in the rivers and place guards along the banks to keep the hungry people from fishing them out. Slaughter the pigs and bury them, and let the putrescence drip down into the earth.

There is a crime here that goes beyond denunciation. There is a sorrow here that weeping cannot symbolize. There is a failure here that topples all our success. The fertile earth, the straight tree rows, the sturdy trunks, and the ripe fruit. And children dying of pellagra must die because a profit cannot be taken from an orange. And coroners must fill in the certificate- died of malnutrition- because the food must rot, must be forced to rot. The people come with nets to fish for potatoes in the river, and the guards hold them back; they come in rattling cars to get the dumped oranges, but the kerosene is sprayed. And they stand still and watch the potatoes float by, listen to the screaming pigs being killed in a ditch and covered with quick-lime, watch the mountains of oranges slop down to a putrefying ooze; and in the eyes of the people there is the failure; and in the eyes of the hungry there is a growing wrath. In the souls of the people the grapes of wrath are filling and growing heavy, growing heavy for the vintage.
