Pick a window.
Fall into a rabbit hole.
Strange questions, rough calculations, reverse engineering, circular ideas, experiments, systems, and things worth investigating simply because they make you stop and think.
Could This Work?
Ideas that sound weird but deserve investigation.
Back-of-the-Envelope
Physics + economics + engineering + business + common sense.
Reverse Engineer the World
How ordinary things actually work — from books and elevators to warehouses and ATMs.
Make It Circular
Waste → input. Repair. Reuse. Remanufacture. Resource loops.
Economic Archaeology
Work backward from something's price, supply chain, or existence.
Systems & Operations
What happens if this one variable changes?
Numbers Nobody Asked For
Fermi estimates and ridiculous quantitative questions.
Build / Test It
Ideas that can actually be prototyped, measured, broken, and improved.
Rabbit Holes
Questions where the answer creates five better questions.

Why is a milk packet shaped and made the way it is?
Why a squashy square packet that's chilled and every morning when I collect the packet, it's a crazy feeling. Seriously worth investigating on and may this will tie back to our "Make it Circular" category someday.
If a mountain 1000m tall is eroded by external forces by 0.05mm/year, how long until it disappears and where does it go?
Pretty good to think about
Can I build a diesel locomotive alone?
For this, let's put the question of costs aside because if you are obsessed, there should be nothing stopping you
Can I bleach wash an old book and get back blank pages to write or re-print on?
There are shops out there with old books stashed since 1970s and in this digital sloth age, no one is gonna care for that book
