Perception+sense
A course for building real intuition.
Facts are easy. Sense is hard.
You know a marathon is long and Picasso was important. But how long? Important compared to whom? Perceptense covers the things you should have a feel for: weight and distance, but also art, history, technology, wellness, and the everyday systems around you. Here's the kind of question a module might open with.
A small toolkit, mixed differently.
Every module reaches for the same set of ingredients. Click each one to see a working example.
Anchors are real-world reference points your brain can latch onto. Once you know a few solid ones, every other number snaps into place by comparison.
Calculators let you plug in your own numbers. The point isn't the math — it's seeing how the answer changes when you tweak the inputs.
Visual scale turns abstract numbers into things you can see. Bars, maps, and side-by-side layouts make orders of magnitude obvious instead of theoretical.
Heart rate vs. body size. The smaller the animal, the harder its heart works.
Q&A reveals are quick estimation prompts. Form a guess in your head, then tap to see what's actually true. The gap between guess and truth is where intuition gets built.
If you stacked every person alive today head-to-toe, how tall would the stack be?
How many seconds are in a human lifetime (80 years)?
Interactive games turn classic puzzles into something you can actually play. The Monty Hall problem only really clicks once you've felt the math by tapping a few times — switching wins ~2/3 of the time.
Animations show what static text can't. A wave isn't a number — it's something that moves. Modules use small live visuals to make ideas like interference, orbits, and feedback loops feel concrete.
Two-source wave interference, simplified. Where the rings meet in step, the wave reinforces; where they meet out of step, they cancel — the heart of the double-slit experiment in Module 43.
