Milestone (age 17)

At age 17, constructed a counterexample to the Mizohata-Takeuchi conjecture in harmonic analysis, a 40-year-old open problem, while taking graduate courses at UC Berkeley.

Cairo was born in the Bahamas and was homeschooled, learning mathematics through online resources including Khan Academy. By age 11 she had completed calculus, and by her mid-teens was reading advanced undergraduate and graduate-level mathematics texts. She moved to California at 16 and enrolled in graduate math courses at UC Berkeley, where she disproved the Mizohata-Takeuchi conjecture as a side project.

Hannah Cairo's leverage provenance

Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Hannah Cairo's outcome attributable to any origin.

Luck is not a leftover score.

Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.

Within Researchers / independent engineers, Hannah Cairo's starting-advantage total is at the 41th percentile. Separately, their built or converted leverage total is at the 10th percentile. Other T4 profiles average 5.7 / 24 starting advantage and 10.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary

Cairo was homeschooled in the Bahamas and learned mathematics largely through online resources like Khan Academy, completing calculus by age 11. She found the Berkeley Math Circle's online summer program at 14, which connected her to a community of young mathematicians. After moving to California at 16, she enrolled in graduate math courses at UC Berkeley where professor Ruixiang Zhang assigned the problem that led to her disproof of the Mizohata-Takeuchi conjecture. Family background beyond homeschooling is not documented. The isolation of homeschooling may have created urgency to find mathematical community.
