The reason snow appears white has to do with those beautiful natural artworks we call snowflakes. When it snows, “there’s a lot of traffic on the way down,” says Belles. The air, he explains, is riddled with tiny particles like dust, soot, and pollen. For a snowflake to form, a freezing water droplet attaches itself to one of those floating dust, soot, or pollen particles.
As that ice particle falls, more and more minuscule bits of water vapor freezes to it. Due to the way water molecules bond together when they freeze, a tiny hexagonal form begins to appear. And eventually, you end up with a beautiful six-sided shape we call a snowflake.
[...]
Sunlight “emits all colors of the visible spectrum: red, orange, yellow, blue, green, indigo, and violet.” When these colors hit snow, each multi-sided ice crystal, or snowflake, scatters the colors like a tiny prism. All those colors shine equally in all directions, and our eyes, in turn, perceive all those colors colliding as white.
But why then does ice and snow look distinct, one clear and one white? “The difference between ice cubes and snowflakes is how light reacts with them,” says Belles.
“Sometimes with an ice cube, the light will be able to go straight through it. But with snow we’ve got this kind of broken mirror effect, with light bouncing off of all of those jagged edges.”
Probably a good question to ask my son to reason through once he understands the different ingredients making up the explanation...
It's also interesting we go from an international space station to something that seems to be solely driven by US companies. I wonder what the other agencies will go for, and whether they still will be involved.
The International Space Station (ISS) is a large space station that was assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). As the largest space station ever constructed, it primarily serves as a platform for conducting scientific experiments in microgravity and studying the space environment.

different MSTR securities are structured
Right, they are selling lots of derivative stuff these days now, no?
in the event that things go south
That friend really bought into the idea that big crashes are now a thing of the past with the institutional interest. Probably watched too much Saylor propaganda~~
Overall, hard for me to see an upside to it all, even if I were to want to play Wallstreet games.
Good timing, a good friend, who unfortunately likes to shitcoin, tried to convince me today to get into MSTR. His take is that because currently it's trading at (or below?) Bitcoin value it's a good deal. Taking off the maxi-hat, why is this a good/bad idea?
This looks really cool! How long did it take you to make it all? You have a background in mathematics?
I guess that settles it?
I didn't know Citron Research.
I read the about page, but what's the extra context I'm missing? You mean it's a hit job because they are anti Wall Street?
Thanks for reaching out.
We all make mistakes. He left a few apology messages.
Btw, predyx looking slick, after my brief hiatus.
The fact he gets zapped a lot is indeed linked to his online following. This gives him extra sats.
But here, @PlebQR is not linked to one's online footprint. You pay the LN invoice, and then wait for a local to pay your QR code using fiat. It's a way for locals to "buy" bitcoin by paying someone else's fiat bill. And the way it is currently incentivized is that the exchange fee is in favor of the local. A few minutes waiting at a restaurant for your bill to settle does not seem like too bad an experience.
Erdos Problem #397 was accepted by Terence Tao
There is something beautiful in Terence being the one accepting the solution to one of these problems.
I guess he used Lean to check it?
I didn't know nefarious is considered antiquated.
By the way, you don't need to speak the language to become Scrabble World Champion.
Any of the Blockstream people working on post-quantum-Bitcoin, cfr #1367227
It'd be refreshing to have some technical people shine in on the topic.
Sorry didn't notice I'm just a miserable dupe: #1403077
He would have been cancelled a few times already ;)
Yeah, his books show he excelled at self marketing. I read somewhere he retold every story in many ways and adjusted them based on how people best reacted to them to build his legacy.
