A foundational model for understanding the nature of knowledge along two fundamental dimensions. The first axis runs from A Priori Knowledge (knowledge independent of experience—math, logic, conceptual truths) to A Posteriori Knowledge (knowledge dependent on experience—empirical facts, scientific observations). The second axis runs from Propositional Knowledge (knowing that—facts, information) to Procedural Knowledge (knowing how—skills, abilities, practices). These two axes create four basic knowledge types: a priori-propositional (mathematical truths), a priori-procedural (knowing how to reason), a posteriori-propositional (scientific facts), a posteriori-procedural (knowing how to ride a bike). The model reveals that "knowledge" isn't one thing—it's a family of cognitive achievements with different sources and different forms.
The 2 Axes of the Knowledge Spectrum "You say you know it. The 2 Axes ask: know that or know how? Know from reason or from experience? Knowing that 2+2=4 is very different from knowing how to ride a bike. Same word, different kinds. The axes help you see that 'knowledge' covers a lot of territory—and treating all knowledge like math is a category error."

DJI Neo 2

The glow-up sequel in the Neo drone lineup — an ultra-light, palm-launching flying camera from the Neo Series that basically says, “Who needs a controller?” Built for instant vlogging, spontaneous family moments, and solo adventures that deserve cinematic main-character energy.

Me: "It's all thanks to the DJI Neo 2"

2 inch beetle

Definition:
When a joke, reference, or metaphor technically makes sense… but completely flies over the other person’s head, forcing you to realize you’re speaking a different language.

It’s the moment mutual understanding shrinks to approximately two inches.
2 inch Beetle
Example:
Person 1: “I need to go nuke the toilet.”
Person 2: “Nuke the toilet?”
Person 1: “2in 🪲”

Usage:
“Bro tried to explain the meme lore and hit me with a 2in beetle.”

Murder Mystery 2

Murder Mystery 2 (MM2) is a game on Roblox that attracts exploiters, TikTokers who make crappy edits, kids who want to be obnoxious, 70 year old men with cutesy anime girl avatars, and emos with no real accomplishments in life who want to show off how good they are at the game and their elite passes. The game itself is fun and pretty chill if you want to kill time, but the kind of people that play it make it suck.
Friend #1: "Hey. You wanna play Murder Mystery 2?"

Friend #2: "Nah. Last time I played that, there were at least three exploiters coin farming and flinging me off the map."
