   Well, what I could find quickly comes from the 1960s, out of Avco Laboratories and the Naval Research Labs: "Plasma Diagnostics in Supersonic Flow Containing Cesium and Potassium" [1] Burn Cs in a rocket engine, check for absorpti

   I doubt it was a nuclear explosion in the usual sense of that term - a fission chain reaction lasting <~ 100nsec with liberation of at least a few kilotons of energy. A real nuclear explosion - even a small one - is hard to mistake or co

   For me, it's odious because it's in the vein of: "If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him." [1] I think it's politically motivated ab

   I think the oxygen in the tree materials is already combined with carbon in the form of CxHyOz hydrocarbons, where x,y,z = atoms of the respective atomic species. Burning cellulose (poly-C6 H10 O5) to CO2 and H2O would require (for each mol

   Isn't it 20% of sequestered carbon , not CO2? Burning that carbon to CO2 requires oxygen, which will deplete the atmospheric reservoir to some degree.

   Is it known whether clothing generates a large fraction of microplastics? If so, switching to cotton and other non-synthetic materials might make a difference.

   Yes, there is. But it isn't humans who first discover our galaxy's core explosion, but Pierson's Puppetteers (1). Fun stories by Larry Niven in his "Known Space" series. (1) https://en.wikipedia.org&#x2F

    At some point, the price is unacceptable in light of the benefits conferred. And Cloudflare isn't a utility. I agree with Cloudflare's decision. I hope whichever host 8chan runs to will do the same. Free speech is not a suicide pa

    I had this problem too on my 2015 MPB, when Apple went from Magsafe 1 to Magsafe 2, which was (vertically) thinner. The Magsafe 2 easily disconnected when there was even a little vertical torque. I bought a Snuglet, a thin metal shell that

    Thanks for this, it's extraordinary. Brings back such exciting memories from that time. I hope I live to see a crewed launch with Mars as the destination.

    Perhaps just a dose integrator with an alarm limit? There's probably a total dose above which you could likely say "this is a mistake". A dose integrator would be a detector + an integrator independent of the therapeutic deli

    I thought so too, until I read this New Yorker article [1]. It’s about a site in the Hell Creek formation that seems to show, in incredible detail, what happened in the first hour after the Chicxulub strike a couple thousand miles away. It

    Implicit in your view is the assumption that depression is a choice. Current medical understanding of depression doesn't support that assumption. Your last sentence shows how readily that assumption leads to dismissive blame. That does

    If as GP said the bulb fault is sensed as resistance is too low, putting a resistor in parallel with the LED will reduce the resistance even further. I think it's the I^2R loss in a (series) resistor that makes using a resistor problem

    Yes. H2 is easily dissociated by UV. (Re)combination of 2H0 (two neutral hydrogen atoms) can't happen in the gas phase without a third body to take away the recombination energy. Quantum mechanics again. So there has to be a third thin

    I’m curious why the helium hydride (HeH) would form before H2 (molecular hydrogen). Hydrogen (single atomic form) should have formed a larger fraction of post-bang elements than helium (and much more than lithium). I didn’t see anything in
