    This is actually a result of changes to our larynx and stuff, which allows us to make such a variety of sounds when speaking. In other animals (and human babies), the air and food tubes are physically separated at rest. But in humans, our epiglottis can’t properly keep things separate because our larynx is further down in our throat.

    So, I’m gonna have to deny this request on the grounds that it will necessarily break the speech feature, which many of our users depend on heavily.






  • Correct. Initially, Newton didn’t have indigo in his list for the visible spectrum, but he wanted seven colors instead of six because it matched up with the number of notes in music (and because he liked the number). So at some point there was discussion of removing indigo entirely because it’s kinda just a shade between blue and violet that the human eye just isn’t as good at distinguishing compared to the other colors. But the neat thing is that what people back in Newton’s time called blue and indigo is more akin to what we today call cyan and blue (they know this by looking at his labeled drawings of the light scattered by prisims). Now the spectral colors are: red, orange, yellow, green, cyan, blue, and violet.





  • Luckily, it’s a linear relationship and they gave us the temp change per slap. So, if we assume the chicken has thawed in the fridge (40°F) and we want to reach 165°F for food safety, we only need

    (165 - 40)°F * (5°C / 9°F) / (0.0089 °C / slap)
    = 7803 slaps
    

    Although, to be honest I think this would only work for a spherical chicken in a vacuum, as otherwise you’d be losing too much heat between slaps. And even in a vacuum, you’d lose some heat via radiation… So really, you should stick a temperature probe in there and just keep slapping until it reaches 165°F. Don’t even bother counting.

    Sorry for the silly units, I only know food safety temperatures off the top of my head in °F.


  • Get a skein of medium-weight yarn in a light color (it’s easier to see what you’re doing) and whatever the recommend hook size it says on the label. Then watch some tutorials for basic stitches. I’d start making a little pot holder kinda thing with double or half-double crochet stitch. It’s small enough that you can get used to turning rows, and it’ll work up pretty fast with the medium weight yarn to give you some nice dopamine when you finish.

    I would definitely recommended learning with just regular yarn, nothing fancy, until you get used to it. Yarn with lots of variability in the weight (as i expect plastic bags would have) is going to be difficult if you’re not comfortable with the basics.




  • While i do think life exists elsewhere in the universe, I think the chances of extraterrestrial biological entities coming to our planet is exceedingly unlikely. Space is just too big, and there isn’t any hard evidence that faster-than-light travel is even possible.

    Although, the universe isn’t just big – it’s old. There could be some ancient civilization from an ancient planet that became uninhabitable long ago. If they were technologically advanced enough to escape their solar system before things went tits-up AND were able to live multiple generations fully in space AND they just so happened to set out in our direction, I guess it’s possible that they found us. Even then, i would expect any UFOs or whatever would merely be probes, not the actual biological entities themselves.
