  • When I realize the car or truck ahead of me is emitting something I don’t want to breathe (either because I see it coming out the tailpipe, or because I start to smell it), I want to switch to recirculation RIGHT NOW, not after I navigate through a maze of menus that require me to take my attention away from driving.

    Also, I want temperature regulation based on how hot or cold I feel, not what some thermometer says (and often have different opinions about where the air should be blowing depending on how I feel).




  • 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”.
