  • Yes, i do think the biggest problem is shoving so many different tricks at them at once that it leads to confusion. There was also a bit of frustration from some of my tutees from having to solve the same problems multiple times. Some found it boring and tedious, and some found it confusing and made them less confident in their skills since not all methods they were taught “clicked”.


  • When I was tutoring, i had a few elementary-school aged kids. They’d have homework where they had to do the problems three or so different ways, using each of the methods that they were taught (one of which was always the way I was taught when I was their age). I actually feel like I learned a lot from them, as there were some interesting tricks that I didn’t know before helping with the homework. I think that’s a really good way to approach it, because a kid may struggle with some of the methods but generally was able to “get it” with one of them, and which method was “the best” was entirely dependent on the kid. For me, being able to see which methods clicked and which ones didn’t helped me be more effective as a tutor, too, since it showed me a bit more about how their individual little brains were working.

    But I agree, if you’re not also at least trying to explain why the different methods get you the same answer, it can lead to problems down the line. Some of them saw the “why” for themselves after enough time working at it, and some needed a bit more external guidance (which, considering they were coming to me for tuturoing, I guess they weren’t getting at school). My argument would be that no one really taught me “why” when I was in school learning The One Way to do math either. I still had to figure out little tricks that worked for me on my own, since my brain is kinda weird. It may not have taken me so long to believe that i’m actually pretty damn good at math if I’d done those kids’ homework when I was their age, as i would have had more tools in the toolbox to draw from.

    Yup. There’s also an even older Sumerian myth of very similar content: Enlil (ancient mesopotamian god of air, earth, and storms) thought humans were too noisy and decided to destroy them all with a great flood; I guess he really needed some sleep. Luckily, Enki (god of water, knowledge, and creation) told one guy, probably a priest, Ziusudra, to build a boat big enough for his family and a breeding pair of every animal.

    Sounds pretty familar, right? Couple of names changed compared to the one in Gilgamesh. And, other than having two gods in the story instead of one, it’s almost exactly the same as Noah and the Ark (of course, there is some compelling evidence that the old testament god in the bible was originally multiple older gods that over time got “absorbed” into one God, hence why he has so many different personalities depending on which story you are reading).

    The peoples telling these stories lived relatively close together geographically, and the timing lines up with a period of glacial retreat, meaning flooding was more common due to ice melt, rising sea levels, and and changing weather patterns. Though it’s hard to say if they’re all talking about the same flood or simply using similar stories and motifs to talk about different floods. I tend to think it was just a flood-happy time in the region, and if an entire village ends up underwater i’d say it sure feels like “the whole world” flooded, especially if other peoples you come into contact with have similar stories of their own.




  • 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.


  • In the books, they all could tell something was up with Frodo and refused to let him go alone. In fact, Sam was actually dropping plenty of eaves, dispite his claims to the contrary in the movies, and they puzzled it all out before Frodo even left Bag End. (Fatty Bolger, another co-conspirator who did not make a movie appearance, decided to stay behind to keep up appearances so that the mission stayed a secret as long as possible. He bought them precious time when the Nazgûl were in pursuit, and later played a role in the resistance against Saruman prior to the Scouring of the Shire.)

    yeah, mycotoxins (ie: toxic byproducts from fungi/mold decomposing your food stuffs) don’t always get broken down during cooking. So, while cooking according to standard food safety specs may have killed the mold, their shit is still everywhere ready to fuck your shit up.

    Not to mention that you have to survive an infection before it matters that you immune system learned to detect the infectious agent. Yes, the first inoculation techniques were literally just minor exposure to the infectious agent (eg: grinding smallpox scabs and blowing the resulting powder up the nose – wtf). While it technically worked, the mortality rate was still pretty damn high, just not quite as high as ya know getting smallpox the normal way, and thus really only used when a serious outbreak was occuring. We’ve gotten so much better at making vaccination safer and more effective, because we now know so much more about what is actually occuring biologically and know to use attenuated virus or just the benign protein coat alone to achieve results. Why would you ever want to go back to scab-snorting (or toilet licking, apparently, lol)?


  • 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.
