The original post only gave half the explanation. It’s not that lead exists in general, it’s that lead exists within zircon crystals.
Under normal circumstances that would be impossible, zircon crystals strongly reject lead atoms as they form. There’s no way to stuff lead into the crystal lattice in the quantity we find them there. But uranium and zircon go together just fine, we just have to wait for it to decay into lead. The trouble is it takes ~4.5 billion years for just half of those uranium atoms to turn into lead. So any zircon crystal we find with half as much lead as uranium must be roughly that old
Depends where in the world you are. In the US it was popularized by Dr Kellogg to curb masturbation. He also recommended a few drops of carbolic acid applied to young girls clits to damage the nerves and avoid what he called “abnormal excitement”.
Dude was opposed to pretty much anything even vaguely resembling pleasure, he invented corn flakes as a food to be as bland and tasteless as possible. The only reason they ever became a popular breakfast cereal is because of his brother adding sugar to them despite Kelloggs objections
‘cleanliness’ and ‘looking like their father’ were later justifications after the practice had already gained traction.
I went down a rabbit hole when my mouse started double clicking wanting to know why, especially compared to older mice that seem to last forever. turns out the switches themselves technically haven’t changed or even dropped in quality much over the years, they’ve always used the same shit-tier switches. many modern mice use too low of a voltage and operate out of spec, and the otherwise good enough switches don’t hold up. here’s an hour+ long youtube video about it if you want all the details.
it’s bullshit that it’s necessary, but if you’re willing to solder in new switches you can get better quality ones that will outlast the rest of the mouse for ~$5-10.
my favorite depression meal is an easy rice and beans. buy those flavored rice sides that come in a bag, chicken flavor is a good default option. cook it per instructions, then throw in a drained can of black beans and whatever frozen veggies sound good. don’t even bother heating up the beans or veggies, there’s enough heat in the rice that everything ends up nice and warm. just give it all a stir and you’re done.
the rice sides have enough flavor to make everything taste good as is, but there’s definitely room to toss in whatever spices are within arms reach that sound good.
most logitech mice use the same switches, any Japanese Omron switches will work (avoid the Chinese Omrons). here’s an amazon link to a 2-pack. there’s also a bunch of other switch types nearly as varied as keyboard switches, these are what I put in my mouse, but if you’re just looking to stop the double-clicking the Japanese Omrons are the way to go.
I thought this had to be hyperbole, so I did the math myself. I’m assuming human history is 200,000 years as google says, and we want to narrow this down to the second the bike disappeared. also that the bike instantly vanished so there’s no partially existing bike.
each operation divides the time left in half, so to get from 200k years (6.311×10^12 seconds) to 1 would take ~42.58 divisions, call it 43. even if we take a minute on average to seek and decide whether the bike is there or not it would still be less than an hour of manual sorting
hell, at 60fps it would only take another 6 divisions to narrow it down to a single frame, still under an hour
edit: to use the entire hour we’d need a couple more universes worth of video time to sort through, 36.5 billion years worth to be exact. or a measly 609 million years if we need to find that single frame at 60fps
