This part of Whoop is super lame. It claims that doing NDSR (hybrid meditation/nap) has a negative impact on recovery for me. I think this is likely not causation but a correlation - I do this when I'm whipped so no wonder it correlates with poor recovery. ๐Ÿ‘Correlation ๐Ÿ‘ is ๐Ÿ‘ not ๐Ÿ‘ causation, Whoop

Maybe it's a typo and they just wanted some affordable hosing... For irrigation systems

Google Opinion Rewards has some wild options when it asks where I've been recently. Today, it asked if I went to "Van's pig stands". I didn't. But maybe I should. Does Van have a pig that stands on its hind legs? Does Van sell statues of pigs that hold signs? Must sniff around and report back.

Do paperbacks count for less? Perhaps in part because those come out later?

That was also my thought. Surprisingly, we don't see any initiative aimed at abolishing "critical race theory" or similar. Maybe they smuggle it into "increase the capacity of HBCUs to provide the highest-quality education to an increasing number of students".

"many accredited institutions offer undergraduate and graduate programs with a negative return on investment โ€” almost 25 percent of bachelorโ€™s degrees and more than 40 percent of masterโ€™s degrees". That's evidently accurate - see whoever contributed to this EO. They clearly suffered negative ROI

Have you seen this petition yet? Oppose the layoff of the NIST Atomic Spectroscopy Group

Science needs your help! The NIST Atomic Spectroscopy group is at risk of being laid off. This team is a quiet lynchpin for so many corners of hard tech across medical, defense, energy, semiconductors, and indeed #QuantumComputing. This isn't political, it's an American interest

Been thinking a lot about global population decline recently. Family homes become a worse investment. Economies need to finally allow their workers breathing room to raise kids. Does AI improve per-capita productivity enough to make up for population loss? Who are the leading thinkers here?

I just got the inside scoop on this @natphys.nature.com work from Chitose at JILA last week. Lots of neat tools to add to the atom interferometry belt. Can't wait to dig in!

Tariff Tuesday story: I need to buy some custom parts. We got some quotes from the US and some from China. Even with a 125% tariff, the Chinese parts are still cheaper. So we, a US company, are just incentivized to flush 125% cost down the toilet. Still trying to piece together how this helps...

My son (1.5) really loves typing on my keyboard. He sauntered into my office this morning and assigned me a new action item in some meeting notes:

" edsdsdcrdcZD. ZAZXโ‰ˆโ‰ˆ ย C CJM VRF3 AEFV V "

Still working to clarify the definition of done so I can draft an action plan.

Just a PSA to remind you that laser cooling of atoms is so badass. A colleague snapped a shot of my lecture on Magneto Optical Traps and Raman Sideband Cooling. Atoms ๐Ÿ‘ are ๐Ÿ‘ so ๐Ÿ‘ fun ๐Ÿ‘

I've done my fair share of experimentation with the ol chemex at home, but it's extra "illuminating" to take it all the way to silica beads and lasers. Doing the important science, for actionable life advice. Count me in for those high-velocity laminar flows!

Quantum computers have complex global supply chains. Piecing together the impact of tarriffs on the whole QC industry is going to be ... interesting

Stoked to start my journey on Bluesky! I followed @seanmcarroll.bsky.social here and love the lively discussion I see. I'm looking forward to learning from you all, answers to the deep questions like: wait, why do my people care about the Kardashians again?
