The people who built the stone towns of Gobekli Tepe and Carahan Tepe in Anatolia in Turkey, built and lived their villages so long ago, that the very first historical civilization recognized as such, with cities and writing - the ancient Sumerians - are closer to us in time than to those hunter/gatherer people, who lived near the ~~Atlas~~ Taurus Mountains foothills and the rivers and tributaries that eventually merge into the Eufrates further downstream.

The time between the last living stegosaurus and the last living tyrannosaurus is greater that the time between the last tyrannosaurus and today.

African Wild Dogs decide on when to go hunting by voting. If there is a supermajority of votes in favor of hunting, they will go out and hunt. If that quorum is not reached, they will stay home.

That’s awesome! Maybe they should teach us some of their tricks…

The natural logarithm number e is the most efficient base, Benford's law shows that a collection of numbers where their logarithms are uniformly and randomly distributed, the probability of the first digit being 1 of any of the numbers is around 30%, and most humans can learn echolocation with some training.

In the movie "Catch Me If You Can", the french police officer that arrests Leonardo DiCaprio who is playing a young Frank Abagnale Jr. Is Frank Abagnale Jr.

[-] andrewta@lemmy.world 7 points 5 days ago

Don’t know that. That’s kind of cool.

If you have two arms, you have a higher than average number of arms.

[-] neidu3@sh.itjust.works 19 points 5 days ago* (last edited 5 days ago)

And if you have one skeleton in your body, you're below average.

[-] idiomaddict@lemmy.world 9 points 5 days ago

Well now wait, if pregnant people have four (or more) arms, we’ve got to have more than half as many pregnant people as people missing one or more arms, right?

Almost all web traffic now uses the utf-8 encoding, a clever hack which works because ascii is a seven-bit code but web traffic uses 8-bit bytes.

  • If the first bit is 0, treat the byte as ascii.
  • if the first bit is 1, treat the byte as part of a multi-byte unicode character.

multi-byte characters in utf-8 can officially be up to four bytes long, with 11 of those 32 bits used for tracking the size of the multi-byte block. That leaves 2^21 code points available, about two million in total, easily enough for every alphabet you could need to write on a website, and all without breaking ascii.

[-] ryedaft@sh.itjust.works 4 points 4 days ago

Oh, I wondered about why there weren't more characters in the ASCII code set.

[-] nycki@lemmy.world 3 points 4 days ago

yep! the ascii standard was originally invented for teletypewriters, and includes four 'blocks' of 32 codes each, for 128 in total, so it only uses seven bits per code.

the first block, hex 00 - 1F, contains control codes for the typewriter. stuff like "newline", "backspace", and "ring bell" all go in here.

The second block has the digits are in order, from hex 30 = '0' all the way to hex 39 = '9',

The uppercase alphabet starts at hex 41 = 'A', and exactly one block later, the lowercase alphabet starts at hex 61 = 'a'. This means their binary codes are 100 0001 and 110 0001, differering only in a single bit! So you can easily convert between upper and lowercase ascii by flipping that bit.

The remaining space in the last three blocks is filled with various punctuation marks. I'm not sure if these are in any particular order.

The final ascii code, 7F, is reserved for "delete", because its binary representation is 111 1111, perfect for "deleting" data on a punch card by punching over it.

There is a giant hexagon on the north pole of Saturn.

It's more evidence that hexagons are the bestagons.

Emoticon :) has etymology stemming from emotion + icon. Tis from the 80s, early computer stuff

Emoji 😊 is japanese, from 絵文字 which is like, drawing + character, basically. It's a word MUCH older than computing.

False cognates. Sound similar, similar function, nothing to do with each other.

[-] HeyThisIsntTheYMCA@lemmy.world 8 points 4 days ago

There's a :) in a typewritten cookbook I have from the 40s. I don't know how widespread smileys were back then, but they existed.

[-] jxk@sh.itjust.works 5 points 4 days ago

My favourite false cognate is the plural ending -s in French and English. The English one has Germanic roots, while the French one come from Latin accusative plural -as/-os. They are unrelated etymologically.

Honestly literally anything about QR codes. Those things are insane. Did you know there's a very obvious 01010101010101 pattern in it if you know where to look?

The number of possible combinations of cards in a standard 52 card pack is so large that there is very little chance that any two packs of shuffled cards that have ever existed have ever been in the same order.

52 factorial is a larger number than the number of atoms in the observable universe.

[-] Valmond@lemmy.world 14 points 5 days ago

Chess positions are like that too, after any "main line" it quickly becomes a never played game...

[-] triptrapper@lemmy.world 1 points 3 days ago* (last edited 3 days ago)

Correct me if I'm wrong, but it seems more realistic to say:

  1. Playing the same game twice is unlikely because of the number of possible games, OR
  2. It's possible the same game has never been played twice, OR
  3. After a certain number of moves, it's very possible to create a never-played game

I'm certain I've played the same game multiple times, because I suck at chess and I fall into the same obvious traps over and over.

[-] Valmond@lemmy.world 1 points 2 days ago

You were in a main-line then.

And what you states is matematics/statistics, but if you take that ar face value, you could just win the lottery 10000 times in a row too.

Kevin Spacey’s middle name is Spacey.

And that’s a rock fact.

[-] neidu3@sh.itjust.works 14 points 5 days ago

For anyone else wanting to look this up: yep. His full name is Kevin Spacey Fowler. Not Kevin Spacey Spacey as I thought OP meant.

if you like big numbers: there are significantly more ways to shuffle a deck of 52 cards than there are atoms in the observable universe.

Every shuffle of the deck is almost certainly unique since folks been shuffling cards.

edit: ahh nice someone posted this exact fact at the top level lower down!

On Titan, you could strap on wings and fly around.

Moreover, the atmosphere is >5% natural gas, but without oxygen you can't burn it. I suppose oxygen would be considered the fuel in that case and you'd pipeline that instead? And being able to breathe would be a nice side-benefit.

Early cycling laws and rights predate the invention of the automobile by decades. So it is actually the car that is the invasive newcomer.
