    perfectionist mindset - as one is writing,

    I think an “M-Dash (perfectionist mindest— as one is writing,)” would be more appropriate than an “N-Dash” in your statement. No ‘nested’ parentheses needed (unless you’re looking to add non-essential (though insightful) info to your sentence); but the type of… “PAUSE” makes all the difference

    Incomprehension of fraction to decimal conversion is why 90% of people who say they are bad at math, say they are bad at math

    I feel called out. I was in high-school Calculus (11th grade) before I “truly” understood fractions. Like, I honestly somehow managed to make it to Calculus without knowing how to add and subtract fractions without a calculator. Thought I was dumb in math until 9th grade algebra, and didn’t start becoming a bit of a math nerd until Calculus




  • Nurse here: we ask ‘orientation’ questions as part of our assessment

    I had a younger patient going through the straights with hallucinations (newly diagnosed schizophrenia)… and I had been asking the same questions (as we do) a lot

    So I asked them once again, “Do you know why you’re in the hospital?”. Their response: “Deez nuts!”

    I always appreciate a good “Deez nuts” joke, but that one has been my favorite so far. The volition on their face and the shitty smirk; they’re completely tied down with a guard because they would occasionally be violent… but hot damn, that was a zinger.

    I counted their response as oriented— they know what they did lol










  • Thank you! That’s pretty neat. I tried 27% of 65

    I added two 10% increments (6.5+6.5)… but instead of adding 0.65 (1%) seven more times, I added a 5% increment (6.5/2 = 3.25) and then 2 increments of 1%

    So 6.5+6.5+3.25+0.65+0.65 = 17.55

    I still had to use a calculator to add those weird numbers (and also check my work), but it does seem really practical for easier numbers. I usually need percentages for pricing (i.e. discounts/tipping), and the percentages are normally in increments of 5%, so that’s pretty useful for figuring out a 15% or 75% of something real quick… or at least get me really close (when talking about something like $X.99)

    Regardless, I appreciate the head trick!

    Edit: I guess I could’ve done 30% and then subtracted 1% twice; but it’s the same issue (of adding weird numbers) with the same outcome anyway. So thanks again!





  • Lower frequencies (like the HF range) can propagate further due to reflection/refraction with the earth and the ionosphere. Increasing the frequency can lead to e-skip and troposhpeheric ducting. But even the HF range has shorter wavelengths than our brains, which operate in much lower frequencies (Hz vs MHz). So you would think that our brainwaves would pass through tin-foil much more easily

    But it’s the tin-foil’s electro-conduction that “foils” the electromagnetic waves’ (i.e radio waves’) ability to pass through it. But you would have to have no gaps in the tin-foil to completely block all waves from passing through. So like, an entire foil suit or a walking Faraday cage.

    TL;DR - it’s not about the length of the electromagnetic wave, it’s the electro-conduction (insulating) property of the tin-foil that matters
