1/ The Confusion Locator
Feynman said the first step in understanding anything is being honest about what you actually don't understand versus what you just can't explain.
Most people confuse familiarity with understanding.
They've heard a term enough times that it feels known. But the moment they try to explain it, the gaps appear.
"I think I understand [concept] but I want to test that. Ask me to explain it to you as if you're a curious 12-year-old who has never heard of it. After I explain it, tell me: where did my explanation break down or get vague? Where did I use words that assume prior knowledge the 12-year-old wouldn't have? Where did I skip a logical step that I assumed was obvious? Give me a precise list of every gap you found. Those gaps are exactly what I don't actually understand yet."
The gaps this prompt surfaces are more valuable than anything you'd learn from re-reading the source material.
Because they're your specific gaps.
Not the gaps of the average reader.

2/ The First Principle Finder
Feynman never started from the middle of a subject.
He always started from what was actually true at the most fundamental level the irreducible facts that everything else in the field was built on top of.
His first Caltech lecture didn't start with Newton's laws.
It started with the atomic hypothesis. The one idea that if everything else was lost to science would contain the most information in the fewest words.
"I am trying to understand [subject]. Don't teach me the standard curriculum. First: what is the single most fundamental true statement about this subject? The one idea that if I understood it completely would make every other concept in this field easier to learn? Build my understanding from that single statement outward, adding only one layer of complexity at a time, and stopping to check whether each layer is actually clear before adding the next."
The student who starts from first principles always overtakes the one who started from the textbook.
Because foundations compound.
Surface knowledge doesn't.

3/ The Analogy Builder
Feynman's most powerful teaching tool wasn't equations.
It was analogies.
He could make quantum electrodynamics feel intuitive to a non-physicist because he had spent years finding the everyday physical experience that captured the essence of what the mathematics was actually describing.
The analogy isn't a simplification. It's a bridge.
"I am struggling to intuitively understand [concept]. Don't explain it using the standard technical language. Instead: find the everyday physical experience, familiar object, or common situation that captures the essential behavior of this concept. The analogy should work without any prior knowledge of the field. Test your analogy by explaining what it gets right about [concept] and where it breaks down — because every analogy breaks somewhere and knowing where is part of the understanding."
The moment an analogy clicks is the moment abstract knowledge becomes usable knowledge.
Feynman knew this.
Most textbooks never learned it.

4/ The Teaching Test
Feynman's most famous learning technique is also his most misunderstood.
Everyone knows "teach it to a child."
What people miss is the second half.
When the explanation breaks — and it always breaks somewhere — you don't go back to the book and re-read it.
You go back to the fundamental principles and rebuild the explanation from scratch.
The rebuilding is the learning.
"I want to use the Feynman technique to learn [concept]. First: let me explain it to you in the simplest language I can. [Write your explanation here.] Now: tell me exactly where my explanation broke down, got vague, or relied on terminology I didn't actually define. For each breakdown point: don't just tell me what's wrong. Give me the simplest accurate explanation of that specific piece so I can rebuild my understanding from the ground up. I want to iterate this until I can explain the full concept in plain language with zero gaps."
Iterate this three times on the same concept.
By the third iteration you'll understand it better than most people who've studied it formally.

5/ The Integrated Understanding Test
Feynman's final test for genuine understanding was performance under pressure.
Not a quiz. Not a recall exercise.
A novel problem that required combining everything learned into something that had never been explicitly taught.
Because real understanding isn't knowing answers.
It's being able to generate answers to questions you've never seen before.
"I have been learning [subject] using Feynman's method across these concepts: [list what you've covered]. Now give me a novel problem something that requires combining at least 3 of these concepts simultaneously to solve, that I have definitely never seen before, and that has no single right answer but does have better and worse answers based on how deeply I understand the material. After I attempt it: tell me what my answer reveals about where my understanding is genuine versus where it is still surface level. What would Feynman's answer look like and what does the difference between his answer and mine reveal about what I still need to work on?"
This is the test that separates studied knowledge from owned knowledge.
Feynman gave versions of this to his Caltech freshmen.
It's the hardest test in any subject.
It's also the only one that matters.

It's also the only one that matters.
Feynman spent 40 years at Caltech doing one thing.
Making hard things simple.
Not dumbing them down. Making them genuinely clear.
He believed that if you couldn't do that, you didn't understand the thing yet.
No exceptions.
Not for Nobel laureates. Not for graduate students. Not for anyone.
These 10 prompts run his standard on whatever you're learning.
Not to make you feel smart about a subject.
To find out whether you actually understand it.
