Dark matter exists -- an occasional reminder. The first evidence for dark matter came from the dynamics of galaxies and clusters of galaxies. But these days that is not our *best* evidence. 1/n

But now using their new model, which includes the first-ever use of a ‘free-space link’ for this purpose (essentially, laser pulses of data going through the air instead of a cable,) the University of Colorado's BACON team (Boulder Atomic Clock Optical Network) has now measured this ratio reliably out to 18 digits.”

The whole post is worth reading, especially the part about how they exploited someone trying to exploit the system: “Specifically what happened was the oracle detected a tx in the mempool trying to front run a price update. It then implemented a sandwich attack to raise the exchange fee to 99% for that transaction by sending one tx with higher gwei to raise it and another with lower gwei to drop it back down to the normal rate. Here is the transaction that slashed his funds by 99% and sent them to the feepool to be distributed back to SNX stakers.”

The two sides ended up haggling over whether peacocks were bigger than geese. (The answer: a peacock is a “large bird”.)

“Seven competent people were given two causal studies to replicate from scratch. No two people even report the same sample size and the standard deviation across estimates was 4x SE of original!” replication crises go brrr.

https://noahpinion.substack.com/p/against-hickelism Noah Smith argues against Jason Hickel’s worldview. Max Roser also has similar issues with Hickel. I found it pretty interesting that one of Roser’s points is that $10/day is a overly low number for poverty (see

@Noahpinion Had a long discussion with him this morning about it. A wild discussion. But we did at least finally understand why we disagree about the need for growth: He believes that adjusted for prices in the country, $10 per day is a "very high poverty line".

Max Roser @MaxCRoser

@jasonhickel @JKSteinberger Ah thank you very much Jason. That explains it. Then we disagree about our notion of who a poor person is. I do believe a person who lives on just $20 or $25 per day is a poor person. Your poverty line of $10 is a third of the price of your own book. That’s very little. https://t.co/uE1asjjMBX

New Paper! We find that subjects think you are less at risk of COVID infection when engaged in morally good actions, and more likely to catch COVID while doing morally bad things. In other words, risk judgments are systematically skewed.

Lab leak:

I’ve collected various articles that looked interesting on the topic of whether covid leaked from a lab. I’m still not sure what to think, and haven’t had the time to do a deep dive, but I figured I’d put all the articles I had saved in one place.
