just a mouse with some imaginary friends. we like natural science, abstract math, ancient history, and stuff.

i) A class X is 𝑡𝑟𝑎𝑛𝑠𝑖𝑡𝑖𝑣𝑒 if every member of a member of X is a member of X.

Note: this implies "members of members of members" of X are also members of X, and so on all the way down.

ii) A set is an 𝑜𝑟𝑑𝑖𝑛𝑎𝑙 if it is transitive and well-ordered by ∈.

@mirandaisrisen i've never watched it, but i suspect it's a fairly loose and highly sensationalized connection between the show and actual mathematical forensics.

@SpottlessMarxx this is not based on "conditioning", it's my conclusion based on a lifetime of studying math, science, and programming. no the terrain is not the map - the universe has an existence independent of our mental machinations.

[little grey mouse 🐭 @mouse_math]

i don't believe "mathematics is the language of the universe". the universe does what it does, it doesn't need a "language". math is a human attempt to describe the universe, and as such, it is an abstraction, an approximation, and at least one step removed from reality.

@Scottcrates Phoenix is such a sprawling urban area, this can happen in a location and the rest of us are totally unaware of it.

I saw the forecast for possible hail today so I said “no thanks” and stayed home.

This is what happened at the office.

@WandawomanW yes they are.

[little grey mouse 🐭 @mouse_math]

not only is mathematics a fascinating field of study on its own, its intersection with science is broad, its history is rich, and it even serves on social media as a test tube for the Dunning–Kruger effect.

@Colwiz yes, i am aware that both Gödel and Einstein embraced what i would summarize as "Platonic realism", however it's worth noting that this is out of step with the views of most of their coworkers, which i call "formalist idealism".

[little grey mouse 🐭 @mouse_math]

@thompsryann yes i do.

@proofchecker that's basically the philosophy called "mathematicism".

[little grey mouse 🐭 @mouse_math]

@DiracDeltaFunk not really, considering much of math was invented by scientists for that purpose. it's like saying its crazy that geometry is so good for designing buildings.

[little grey mouse 🐭 @mouse_math]

@ChristianJF27 no i think you're engaging in sophistry. if no conscious beings existed, who would be doing the imagining and the mental operation of dividing?

[little grey mouse 🐭 @mouse_math]

@w4xyy some structures are embodied in reality, but humans have to add the abstraction themselves. there's no inherent similarity between 3 trees and 3 stars, other than the human made abstraction of number. however much of math (such as advanced set theory) has no parallel in reality.

[little grey mouse 🐭 @mouse_math]

@Colwiz i said i "believe" this, not "know" this. my belief is based on a life-long study of mathematics (both pure and applied) and science.

[little grey mouse 🐭 @mouse_math]

@entropy99999 that philosophy is called "mathematicism".

[little grey mouse 🐭 @mouse_math]

@JoelTHpostHack there are large domains of mathematics which have nothing to do with science or the empirical universe (such as advanced set theory) - they only chart out areas of our minds.

@Nguyen_anime3 you're my idea of an all-american girl.

This is cool.. lol thanks !

Spoiler alert: NO!

This guy is the alpha male we keep hearing maga talk about?

Holy fuck 😂😂😂
