It is 2020, and it is time to talk about the thing on everyone's mind: destroying the moon.
There was actually a US plan to nuke the moon (Carl Sagan was involved) in the Cold War: Project A119. But the US decided to do the Apollo Program instead. 1/3 en.wikipedia.org/wiki/Project_A…
Sadly, actually blowing up the moon is outside of humanity's reach, it would require 600M of the biggest nuclear bombs ever built & Saturn Vs to launch them
So how about just writing on the moon. It is hard to do with nukes, requiring 1M warheads & 3,000 Saturn Vs per letter 2/3
Better to launch asphalt and paint the moon- just 2,000 Saturn Vs per letter. To write "hello" you would need 10,000 rockets, (~$1B each in today's dollars). So, around $10 trillion, give or take, only 1/8 of the yearly gross world product. Good deal! 3/3 canmom.tumblr.com/post/863420496…
Researchers left 17,000 wallets on the streets of 355 cities, some empty, some with money. Contrary to the predictions of economists, people everywhere were more likely to return wallets with money in them. But rates did vary from country to country. science.sciencemag.org/content/365/64…
The researchers argue that people are more likely to return wallets with money because they don’t like to feel like thieves, something backed up by a second experiment where they added even more money (the “BigMoney” condition in the graph) to some of the wallets.
As for some of the differences between countries, the researchers explored it in an appendix. Though the analysis was weak (it was posthoc & based on correlations with lots of confounds), it suggested that universal education & democratic institutions are linked to civic honesty.
As we grapple with social media & other new tech, it is worth knowing Historian Kranzberg's 6 Laws of Technology, in a 🧵:
1st Law: “Technology is neither good nor bad; nor is it neutral” - many problems occur when benign technologies are used at scale. Think DDT (or Facebook)
2nd law: “Invention is the mother of necessity” - new technologies, as they scale, require their own suites of innovations. Self driving cars have pushed development of new sensors, phones ever better cameras, etc. This is a good rule for entrepreneurs looking for new markets.
3rd law - “Technology comes in packages, big and small” Technology is all about systems, you can’t study individual things in isolation. One issue with blockchain is that it doesn’t fit well into the social, organizational, and technical systems that it is supposed to replace.
So chess is having a moment thanks to the Queen’s Gambit (see the chart from @DataIsBeautiful). It is also a subject of a lot of social science research. So, a thread of findings on ♟that tell us things about intelligence, luck, and how we learn 1/n
First, chess is often viewed as a game that makes players smarter at other tasks, but the research shows that isn’t true. You don’t need to learn chess unless you want to learn chess! 2/
A paper I think about all the time: In an experiment where people are asked to sit quietly for 15 minutes & enjoy their thoughts or else self-administer 𝗽𝗮𝗶𝗻𝗳𝘂𝗹 𝗲𝗹𝗲𝗰𝘁𝗿𝗶𝗰 𝘀𝗵𝗼𝗰𝗸𝘀, 2/3 of men and 1/4 of women choose to shock themselves. erinwestgate.com/uploads/7/6/4/…
Also if you haven’t read the fine print over the graph...
Everyone in the experiment had already had a chance to be shocked, so it wasn’t new to them & they knew it hurt. The experiment is covered more in this neat summary of the research on thinking for pleasure - why it’s good, and why we hate it. nickbuttrick.com/files/Advances…
Scientists have always had a thing for Middle Earth. It has been the subject of many published academic journal articles, as well as some great analyses by scientists from their disciplines. Here are some good ones, the more elaborate the better... 1/n theatlantic.com/health/archive…
Let’s start with geology, and geologist & science fiction author @katsudonburi’s issues with Tolkien’s mountain ranges (written before plate tectonics was a known thing) 2/n tor.com/2017/08/01/tol…

People spend 15% of work in meetings (managers spend 50%!) & post-COVID meetings are up 14%. But we spend little time trying to make meetings better, despite the fact that there is a whole subfield of research on the topic! Here is a review of findings. researchgate.net/publication/32…
Here’s the highlights as emoji:
Before the meeting...
✅only meet if needed
🐁keep meeting sizes as small as possible
🎯set clear goals & outcomes
📄have an agenda that all review in advance
⏰make it short & relevant to all invited 2/4
During the meeting...
⏱arrive on time
📋follow the agenda
🙋♀️🙋♂️everyone participates
💻📱never multitask
⚔️intervene if mood turns negative
🤪humor helps performance
🙅♀️leave time for objections
🗳Let everyone help decision-making. If a decision is made, tell everyone
