Julia Child did some 400° cooking, for a science-oriented TV series called “The Ring of Truth”: https://www.youtube.com/watch?v=WQ3mjb9BSaU&t=850s
Later in the episode, she got to cook a diamond to amorphous carbon. “I’ll remember that recipe – one carat diamond, two and a half hours, three thousand degrees”: https://www.youtube.com/watch?v=WQ3mjb9BSaU&t=1458s
They’re similar in some respects, different in others; this happens to only show ways they’re similar. Specifically, it only shows dipole (two-pole) fields, with the field lines running from one pole (North or +) to the other (South or -).
But there are also electric monopoles: things that’re only + (e.g. protons) or - (e.g. electrons), which’ll have field lines radiating out in all directions rather than looping back. Magnets are different in that as far as we know, magnetic monopoles don’t exist. Every North pole’s directly attached to a South pole and vice versa. You can get magnets with more than two poles, or even more complex arrangements (e.g. refrigerator magnets normally have alternating North and South stripes), but they’ll always have equal amounts of Northness and Southness, so the net magnetic charge is always zero.
Another (related) difference is that moving electric charges (e.g. electric currents in a wire) create loops of magnetic field. That is, the field line just goes in a circle around the moving charge, rather than from N to S. Since there’s no such thing (as far as we know) as a magnetic charge, that can’t happen with the electric field.
Hmm, I think we should start referring to the toll-like receptors as the awesome-ish receptors.
Another example: there’s a fruit-fly gene named decapentaplegic (which has to do with forming the 15 imaginal discs during embryonic development). When they discovered another gene that interfered with it, but only when inherited from the mother, they named that one “mothers against decapentaplegic”.
But the study, apparently, did not fall into that trap: “I was surprised by the fact that about 90% of the variables assessed significantly predicted conspiracy belief (of 52 variables). These results point to conspiracy belief being even more psychologically complex than I initially presumed,” Bowes told PsyPost.
Are you using the standard xattr command that’s built into macOS? IIRC there’s another program out there by the same name with completely different syntax. Try running type xattr; it should say something like “xattr is /usr/bin/xattr” if you’re using the standard one.
