  • No, the kid’s answer is not “just as right”, it is the correct and expected answer. The teacher’s answer is wrong and proof the teacher doesn’t understand the question. The entire point of the question is understanding that fractions of a whole are relative to that whole and you can’t directly compare fractions from different wholes like that. 5/6 > 4/6 doesn’t mean Luis ate more pizza than Marty, it means Luis ate a larger share of his pizza than Marty ate out of his own.







  • you’ve found out what their opinion on free will and almost every other deep conversation you could have with them in the first few years

    I met my wife when we were 16-17. We are in our 40s now. It’s reasonable to expect that our opinions on such subjects have changed since then.

    But there are plenty of subjects to talk about. How is the current environment in the US going to impact our kids’ lives going forward? Even if we know each other’s general perspectives on life, the universe, and everything, that doesn’t mean we can also predict opinions on complex scenarios and situations.





  • I have aphantasia. I definitely cannot rotate a cube in my mind. I can with great effort and concentration kind of do what you describe, follow where individual edges and vertices would be in space relative to each other, but normally it would just be the idea in my head “there’s a cube and it’s rotating”.

    My go to test for aphantasia goes like this:

    • “Imagine a circle”
    • “OK”
    • “What color is it?”

    People always answer with color and many times with a more detailed visual description, like texture, material, the surrounding scene, etc. I personally would very stumped by that question because when asked to imagine a circle, I just imagine the concept of a circle. It has no color, no texture, no substance.

    My ZX Spectrum clone didn’t have a “tape drive”, it had a cable that you could use to connect any tape player to it. We didn’t have a specialized tape player for it, we attached the same one we played music on.



  • During the communist regime in Romania there was a ban on abortion and the state encouraged people to have lots of kids (sound familiar?). This lead to A LOT of kids in orphanages and not enough resources to properly care for them. Conditions were atrocious, to say the least.

    But, that lead to a lot of research data by following the lives of kids who got adopted from those orphanages. It was determined that 4 month old was the cut-off point from where kids can still recover from traumatic experiences. Kids adopted younger than that did fine, but kids adopted after that age were affected for the rest of their lives. The fact that they didn’t actually remember things consciously did not matter.




    • The light is beamed from the human head in 360 degrees when ever they communicate, visible for up to 1KM

    This sounds extremely impractical. It’s like everyone can only yell at the top of their lungs. At least we can choose to focus on the person we’re interested in and ignore background “noise”. But someone trying to get our attention would be difficult. Now we can just call someone’s name from behind them. Something equivalent would be impossible.
