Use Analogies, Then Check Where They Break

Analogies are the fastest way to understand something unfamiliar. "The heart is like a pump." "Electricity flows like water." "DNA is a blueprint." These comparisons give you an instant mental model — they get you to 80% understanding in seconds. Don't skip this step. A rough model is infinitely better than no model. Start with the analogy and let it carry you as far as it can.

But every analogy breaks somewhere, and finding where it breaks is where real understanding begins. The heart isn't just a pump — it has valves, chambers, and an electrical system. DNA isn't really a blueprint — it's more like a recipe. The point where the analogy fails reveals what makes the real thing unique. Use analogies to get started. Then interrogate them to go deeper.
