With the estimation for the number of particles in the observable universe being 10^80 (or 10^89), you could write one digit of a googolplex (10 ^ (10^ 100)) on each particle in the universe and still run out of space to write the whole number.
Made me realize the fact that there are infinitely many numbers that even if you had the ability to write would be limited by the size of the entire universe!

 No.93622

>>93618
What do you mean by “size”? Are you referring to the space occupied by or the number of particles in the visible universe? Considering the set of all real numbers, your realization requires space to be quantized. If space is continuous then you can create a function mapping every real number to some portion of space. As even though, the total space is a finite number, the cardinality of the set including 0 to any real number is the same as that of all the real numbers.

More precisely, they are logographs, like that of early cuneiform and mayan glyphs as well. Though, a huge difference between chinese characters and other systems is their deep-seated dislike of using characters purely for their phonetic value, so Gardiner's sign list included a mere 763 egyptian hieroglyphs compared to the 2999 totalled today by the jouyou and jinmeiyou kanji.

ALLOW ME
TO QUOTE
A beautiful fragment from the introduction to Léon Wieger's most excellent 1915 Chinese Characters, Their Origin, Etymology, History, Classification and Signification: A Thorough Study from Chinese Documents:

>2. Causes of the gradual transformation of characters. — The first to be noticed, is the complete change in the instruments and material used for writing. The ancients wrote with a sort of fountain-pen, upon small laths of bamboo or smooth wooden tablets.
>Such an instrument traces lines any way it is moved, either backwards or forwards, straight or curved, as one likes, but all equally thick.

>Not long after the catalogue of Li-ssu was edited, Ch’éng-miao invented a pencil of soft wood, ending in a fibrous point, which being dipped in the black varnish, was used for writing on silk strips. Traced with this coarse instrument on a rough material, the rounded figures became square, the curved lines were broken at right angles. But this ungraceful writing being quicker than with the fountain-pen, the wooden pencil was adopted for public deeds, and the li-tzu or official hand, became the current writing, while the lesser seal characters remained the classical writing.

>As it commonly happens, the way being opened, inventions succeeded one another. During his campaigns against the Huns, the general Meng-t'ien is said to have invented or improved the writing-brush, the ink and the paper. This invention was fatal to the characters. — A writing-brush cannot trace lines against the hair, therefore many characters could not be written and were replaced by arbitrary and fanciful sketches. — The materials used further helped to increase the confusion. Paper is absorbent: hence came the thick strokes, the thin strokes and the slabbery letters, which were all unknown to the ancients. — A writing brush, made with stiff and elastic hair, flattens out when pressed down, twists when turned, projects its point when raised up; hence the swellings, the joints, the crooks, which are not intentional, are due to the instrument itself. — Therefore the actual classical writing chieh-tzu, represents the hsiao-chuan as transformed by the writing-brush.

>There is more. The writing-brush galloping, the strokes were connected up, giving birth to the lien-pei-tzu; then it flew, throwing on the paper misshapen figures, which are called ts'ao-tzu. The fancy for these novelties became a rage. At the beginning of the Christian era, a man believed himself dishonoured if he wrote in a legible way. In this crisis, the initiative of a private scholar saved what could still be saved.

The process of making the fanciest wines in the world is befittingly as intensive and precise as one would expect:

https://en.wikipedia.org/wiki/Trockenbeerenauslese

This is the highest sweetness level of wine that you can find. Even if you look outside of wine and consider fruit beverages in general, it's probably naturally the sweetest drink by far. To even start to produce this special kind of wine requires the year's climate be in a vineyard's favor, meaning there's many years that it can't even be produced (although it's become around supposedly every 2/5 years as apposed to around once a decade because of climate change). Why a good year is required is due to the noble rot that's required for the sweetness of the grapes to manifest itself best. In a year where there's lots of moisture the rot turns into grey rot and destroys the crop.

Given that you have a good location and year to grow such grapes, there's still additional challenges to get a bottle of tba wine. As once the grapes are afflicted with noble rot they become shriveled almost like a raisin. Making the extraction process more challenging, and the overall amount of grapes needed to produce a full bottle rise exponentially. Even after all this, there's still a greater level of scrutiny one can use to discern the quality of a tba with which vineyard it came from. Like which river the vineyard lay on, and the mineral content of the soil/soil quality from which the grapes are grown.

To me, one of the most interesting parts of this all is that the production of this type of wine has been tradition for hundreds of years at this point. Which stands as a testament to humanity's ingenuity and creativity when it comes to making better food/drinks for itself.

When looking through danbooru tags I learned that the seiza, the elegantly painful traditional Japanese sitting position that foreigners can't maintain was recognized as an "immoral punishment" if parents forced their kids to do it. I think that means it's illegal now since it mentioned child abuse?

The example was specifically "you were messing around with something important (implying there may have been some damage to it), so now you must sit in seiza for a long period of time"

With "long period of time" being the key, and also the use as a punishment. The law appears to be a prohibition on punishments that cause physical pain or discomfort. I don't think it would be applicable to something like making your kids sit in seiza at a funeral service.

I learned that a game mechanic has a name: the Ubisoft Tower:

https://www.vg247.com/exploring-and-uncovering-the-dreaded-ubisoft-tower
https://tvtropes.org/pmwiki/pmwiki.php/Main/CrowsNestCartography
If you're playing an open world game, but the game uses focal points to guide the player to specific locations to unlock something to make navigation easier, or even possible at all, it's called a "Ubisoft Tower" after the company that made the Assassin's Creed games.
I'd say Elden Ring has them because you start with a dull, primitive map and to upgrade it you need to visit the locations marked on it to grab "map fragments" to get a far more functional map

File:DesertLocust.jpeg (18.39 KB,356x419)

I decided to read up on locusts and they're very interesting. Some interesting facts:
- Locust is simply latin for "grasshopper"
- There is no "taxonomic distinction" between grasshopper and locust, the only difference is whether they're capable of swarming
- Locusts change form when it's time to swarm- serotonin is released if they bump into other locusts at a certain rate within a certain time period which induces physiological and behavioral changes
- The swarming form is called "gregarious" instead of solitary, because they instinctually seek out of other locusts
- The stages of the swarming are, in order: outbreak, upsurge, plague

Previously I had thought swarming was just a simple occurrence of locusts flying to new areas to feed, but it's quite involved. Huh, that's cool

In a completely degenerate electron gas, pressure is no longer dependent on temperature. This fact helps explain how stellar objects like neutron stars and white dwarfs can cool down without shrinking. The pressure from electron degeneracy doesn't increase the temperature/come from the temperature but from the degenerate pressure, which prevents these stars from shrinking while still losing heat.

Reminds me of all the different ant species that do things like herding other insects, growing fungi, or taking slaves. It did make me wonder, a lack of taxonomic distinction would mean that either this particularly complex type of behavior was convergently developed multiple times, or lost by most species. This paper posits the latter, that it may be an ancestral trait:
