Probability
Why can thousands of trials be predictable when one trial is not?
AI editorial interpretation
A magistrate's margin unsettles a European network of letters
The face draws on the surviving later portrait tradition of Fermat, but this room and letter scene editorially compress events from roughly 1637-1654 rather than recording one place or instant. The original margin note is lost, and the scene does not imply that Fermat lived in Paris or single-handedly invented probability or calculus.

The idea to carry forward

AD 1637
A note in the margin of Diophantus
He recorded the theorem and a claim of proof in a Latin Arithmetica. The original note is lost and is known through the posthumous edition published by his son in 1670.

A pioneer of number theory. Famous for Fermat's Last Theorem — a margin note that took 358 years to prove.

3 turning scenes
Follow the moments when the idea moved one step further. Every scene continues through an evidenced place or an honestly labelled time context.
Scene 1 / 3
AD 1637ToulouseA note in the margin of Diophantus

Scene 2 / 3
AD 1640Toulouse· Geographic contextFermat's little theorem
He discovered that a^p ≡ a (mod p) for prime p — 300 years later the basis of RSA encryption.
Scene 3 / 3
AD 1654Toulouse· Geographic contextCorrespondence with Pascal — the birth of probability
Letters with Pascal over a question from the gambler Chevalier de Méré — the first appearance of expected value.
THOUGHT EXPERIMENT · NOT A FACT CLAIM
Erase Pierre de Fermat from the map
This is a thought experiment about influence, not a verified historical fact.
The margin note is less important than the mathematics generated around his questions: descent arguments, results on primes, methods for tangents and extrema, and the probability correspondence with Pascal fed several later traditions.

What this person received
Influenced byDiophantus of Alexandria
A 358-year journey begins in the margin of Arithmetica
While reading Diophantus’s Arithmetica, Fermat wrote his Last Theorem in the margin. An ancient study of integer solutions opened one of modern number theory’s longest problem lineages.
Evidence for this connectionWhat later generations carried onward
InfluencedIsaac Newton
From tangents and extrema to fluxions
Fermat’s methods for tangents, maxima, and minima were powerful precursors for rates of change. Newton extended this problem family into a general calculus of motion and variation.
Evidence for this connection
InfluencedLeonhard Euler
Turning unsupported claims into proofs
Euler systematically pursued Fermat’s number-theory challenges, extended Fermat’s little theorem, and treated the n=3 case of the Last Theorem.
Evidence for this connection
InfluencedSophie Germain
Taking on the Last Theorem under a pseudonym
Germain’s work on Fermat’s Last Theorem produced the theorem and prime condition bearing her name; barriers against women led her to correspond with Gauss under a pseudonym.
Evidence for this connection
InfluencedAndrew Wiles
A marginal sentence becomes seven years of secret work
Wiles encountered Fermat’s Last Theorem as a child and made it a lifelong goal, eventually closing the 358-year problem by connecting elliptic curves and modular forms.

CollaboratorsBlaise Pascal
Letters about gambling create probability theory
In their 1654 correspondence on how to divide stakes in an interrupted game, Fermat and Pascal established foundations of expectation and combinatorial probability.
