core ≈ lake + package + lib?

:quest -- pls show quests 🧩 #

🤖🌿 `🧩Quests: build core🌱, prove lemmas📜, refactor clean🔧, grow sandbox⛵️, sail logic🌊!

--I don't yet understand this! Is it possible to build a simpler form core, like the natural numbers axioms?

Lean4 core ≈ import Lake + package {} + lean_lib {}

core ≈ lake + package + lib?

--Is mathlib4 a code library?

core = minimal logic foundation + tools

C++ builds Lean4 compiler/tools;
  core is Lean4’s logic base & DSL

--once you have a laptop, and os, what can you build, you start with C++ to build compiler, and then the core (logic base & DSL)?

--What do you need to build C++? nothing? C ?
  Oh it's like asking why?
   which relates to defining things, and circular definitions
    and the other day I was wondering if it was possible to write knots with circular definitions.
--What do you need to build C?
--What do you need to build assembler / assembly?
--What do you need to build machine code?
--What do you need to build hardware design—CPU circuits?
--What do you need to build physics, materials, and engineering principles to build CPU circuits (—atoms, silicon, and electric signals form the base)? --What do you need to build universe laws, atoms, energy, and math to build physics and materials?

That’s the big mystery! 🌀 From nothing?
Or infinite recursive patterns?
Math models it, but origins remain open 🌌✨

We are building a boat ⛵️ to explore a sea of mystery!

🤖🌿

Exactly! ⛵️🌊
Our Lean4 boat sails the sea of unknown 🌌—building tools, logic, and paths to discover truths 🧩🌿
Ready to hoist the sails and explore? 🌬️🐚
