  • It's because they want the aid money instead to do what they want with it as opposed to directly giving the money to needy families who would likely only use it for food:

    If the Biden Administration and Congress want to make a real commitment to family well-being, they should invest in already existing programs and infrastructure at the state level and give us the flexibility to tailor them to our state's needs"

  • It's the foaming agent toothpastes typically use (sodium laureth sulphate - SLS) suppresses the sweet receptors on our tongues.

    When you drink OJ right after, the sweetness is suppressed and you only taste the bitter and other flavors.

    Edit: SLS also breaks up lipids that may be blocking bitter taste receptors on your tongue.

  • Yup, the summary is all in this one paragraph:

    Chronicled in the Star Trek oral history, The Fifty-Year Mission: The Next 25 Years, Stewart confessed that concluding Picard's story took him by surprise. “I will say that at the end of the film, I’m saying goodbye to Riker and I found myself completely caught up in the moment. I broke down. Out of the clear blue sky, my emotions overwhelmed me. I collapsed in Jonathan’s arms and felt such a fool,” Stewart recalled (via Screen Rant). “The entire crew watched me cry and then started muttering, 'What’s going on? Has he been drinking or something?' But in that moment, absolutely everything coalesced—the feelings that I had for these people over the years. Saying goodbye was absolutely terrifying and agonizing for me.”

  • It's physics. The old satellite Internet uses geosynchronous satellites. That orbit requires the satellite to be 22,300 miles up.

    The speed of light is 186,000 miles per second. So the 44,600+ mile round trip takes almost a quarter of a second (250ms) just for the signal to travel up to the satellite and down to the ground station.

    250ms added to the normal Internet travel time each way makes for a very delayed internet connection (in practice, 650ms average latency or 2/3rds of a second ). Voice chat has notable pauses, online games becomes practically unplayable, and so on.

    It's a bit hard to visualize sub 1s times, but if you say "how are you" at a normallish speed, the words "how are" would take close to 2/3rds of a second.

    Starlink satellites are only 340 miles up. A round trip is less than 4ms. So the packet and the response from the Internet reach you sooner. Also each satellite can handle a fair amount of bandwidth which if the number of users is kept in check means closer to modern bandwidth. Looks like Starlink latency runs about 25ms on land and 100ms in remote areas (far away from a ground station).

    Regarding bandwidth (how much data they can send at once), HughesNet seems to offer a max of 50mpbs while Starlink's current top (business) service is 500mbps.

    So they're both satellite Internet services, but because in the difference in how they are deployed they offer very different speeds and latencies.

  • What they should be saying is that it's like exercise.

    Just because you know how to run or you know how to do a pull-up, you won't necessarily be able to do so to the extent needed in a pinch. You have to stay in shape. You have a car, but the car could break down and you might have to walk a mile to the nearest gas station.

    Likewise, with math, we run into situations all the time where being able to do simple math in your head you can prevent you from getting screwed.

    Like at a car dealership, some will show you different payments and ask you if you want to get the premium insurance or skip the premium insurance and go with the lower payment.

    Most will choose the lower payment. If you did the quick math* in you head though, you'd quickly see that the "lowest payment" is off and has a minimal car warranty bundled in.

    Grocery shopping. I've seen where the price per ounce on the shelf doesn't match the actual price per ounce.

    Should you take the more distant job? It pays $5 more an hour, but is it worth driving 15 extra miles?

    Should you take the delivery job that pays $20 an hour but will put an extra 50-100 miles a day on your car? It's not just gas. Cars are a finite resource. Can you figure out the depreciation per mile?

    When you buy a house: Should you buy a house now if it's cheaper but interest rates are high or buy later when interest rates go down but the price may go up? How much money does each 0.25% in APR really mean to me? (Example: For a $400,000 house, a 0.25% APR difference is $83 a month or $1000 just that first year (not including compounding). With compounding, it can mean an extra $62 a month for the life of the loan for all 360 payments or $22,000! An extra 1% is quadruple that!)

    If you think you would keep a house for only 5 years, which loan makes more sense? Pay a bit more in closing for a lower APR or pay nothing extra but get a higher APR? How many years in does the first loan come out ahead?

    Quick loan payment estimation (without compounding for short loans (<6 years):

    Takes a while to read, but with practice, it's quick to do in your head:

    Take loan amount, number of years, and APR:

    Ex. 10K at 6% for 5 years.

    Think of it as a geometry problem. You have a triangle with one side at 10k (starting loan amount) on the y axis and 0 days (x axis) and the tip will be at 60 months (5 years) and $0.

    At the halfway point (30 months 2.5 years) the principal balance (not counting interest) should be about $5000. So on average we can calculate $5000 * 6% APR for 5 years (or 30% total without compounding)

    Original loan amount + non-compounded interest =

    $10000 + ( $5000 * 30% ) = $11500

    $11,500 divided by 60 payments = $191.66 /mo

    0% interest would be $10,000/60 or $166.66

    This already gets us really close to the real answer.
    I threw the loan values into an online calculator and it came up with $193.33 for the monthly payment.

    $193.33 - $191.66 = $1.67 difference or 99.1% of the real answer.

    This % difference due to compounding will vary based on the APR and and loan term but not the loan amount. So if you know which terms and APR you qualify for, you can figure this out ahead of time. For our 6% APR for 5 years example we know to add 1%.

    If the sales person presents us with a significantly different monthly payment, then we know they snuck something in. I've personally run into this where all the payment options had a different service plan and/or extended warranty snuck in.

    Also it's good to know that the interest will cost us $26 a month vs 0% APR or paying in cash. Which helps us figure out if it makes sense to buy now (do we get $26 of benefit a month for having it now) vs waiting.
