Every one checked before you read it.
Oddlywise builds critical thinking through micro-learning. One-minute ideas from physics to philosophy, each with an explainer when you want the why, and a short quiz that makes you apply it. Every claim is checked and every number re-calculated before it reaches you.
In 1932, Australia sent soldiers with machine guns to fight birds. The birds won. About 20,000 emus were flattening wheat in Western Australia, so the army sent two Lewis guns and 10,000 rounds.
Why it matters: it's the cleanest example you'll find of using the wrong tool. What worked later was boring: bounties for local hunters, and better fences.
Why did the machine guns fail?
What's in the name
Odd is where the learning is. The emu war, the bias you didn't know you had, the number that doesn't add up. That's the habit we're building. Not more facts, but better thinking: knowing why something is true, how sure to be, and where it breaks.
Subjects, the areas inside them, and how deep you already go. About a minute.
Every card ends with why it matters. Open the explainer for the mechanism, the numbers and the story.
Continue takes the same idea one level further. Next moves you on. Nothing repeats.
A second pass reviews every claim, and code re-runs every calculation.
