Nima Arkani-Hamed
Researchers / independent engineers · Science/Research · milestone at age 26 ·
T1 Global iconMilestone (age 26)
Co-authored the ADD model (Arkani-Hamed, Dimopoulos, Dvali) in 1998 at age 26, proposing large extra dimensions as a solution to the hierarchy problem, which became one of the most cited papers in particle physics and reshaped the field's approach to physics beyond the Standard Model.
Arkani-Hamed was born on April 5, 1972, in Houston, Texas, to Jafargholi 'Jafar' Arkani-Hamed and Hamideh Alasti, both physicists from Iran. His father worked for the NASA Apollo program and later taught earth and planetary sciences at McGill University. The family moved to Toronto, where Nima graduated from the University of Toronto with a joint honours degree in mathematics and physics in 1993. He earned his PhD from UC Berkeley in 1997 under Lawrence Hall, then became a postdoc at SLAC. In 1998, while at SLAC, he co-authored the ADD model with Savas Dimopoulos and Gia Dvali, proposing that gravity's weakness is due to large extra spatial dimensions.

Nima Arkani-Hamed'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 Nima Arkani-Hamed'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, Nima Arkani-Hamed's starting-advantage total is at the 96th percentile. Separately, their built or converted leverage total is at the 55th percentile. Other T1 profiles average 8.9 / 24 starting advantage and 13.6 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
