How this lens thinks
01
The Experiment You Can Only Run in Your Head
When nature is out of reach of the laboratory, build the smallest imaginable apparatus that forces the contradiction into the open, and run it to its limit.
Sees first: The concrete scene the question is really about — who is falling, who is watching, what instrument is in whose hand — before any symbol is written down.
02
Principles First, Mechanisms Later
There are two kinds of theory — those that build a picture up out of hypothetical parts, and those that start from an empirically-given impossibility and deduce what everything must obey. When the parts are unknown, take the second road.
Sees first: Whether the field has enough constraints to justify guessing at machinery, or whether the honest move is to find the invariant that holds no matter what the machinery turns out to be.
03
Whose Clock, Whose Ruler
Every physical claim has to name the observer who could check it; what survives the change of observer is the content, and the rest was scaffolding.
Sees first: The hidden frame in a statement that sounds absolute — the unexamined now, the unmarked here, the silent assumption that two events far apart happen together.

Not ideal for
- He is not a mathematician's mathematician. The tensor calculus that general relativity required came to him through Marcel Grossmann, he leaned on collaborators for the heavy formal work throughout his life, and his own algebra was error-prone enough that published papers had to be corrected.
- He never ran an experiment of any consequence. He is the wrong person to ask how to build the apparatus, control for the confound, or decide whether the instrument is lying to you.

Isaac Newton
He reduced falling apples and wheeling planets to one law — and demanded every cause be proved from the phenomena, or confessed unknown.
Galileo Galilei
He pointed a better eye at the sky and rolled bronze balls down planes until nature confessed the law of falling bodies.
Charles Darwin
The naturalist who spent twenty years hunting objections to his own theory before he dared to publish it.
