History
History: The Name Alhazen
The Scholar
Ibn al-Haytham (965-1039 AD), latinized as Alhazen, was an Arab mathematician, astronomer, and physicist. He pioneered the scientific method through rigorous experimentation, five centuries before Renaissance scientists followed the same paradigm.
His masterwork, the Book of Optics (Kitab al-Manazir), fundamentally shaped understanding of vision, light, and perception. He was the first to correctly explain that vision occurs when light reflects from objects into the eye, overturning the ancient Greek “emission theory” that eyes emit rays.
But it’s his philosophy of critical reading that inspires this project:
“The duty of the man who investigates the writings of scientists, if learning the truth is his goal, is to make himself an enemy of all that he reads, and, applying his mind to the core and margins of its content, attack it from every side. He should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency.”
This approach remains radical: make yourself an enemy of what you read, attack it from every side, and suspect even yourself.
The Scholar the West Forgot
Ibn al-Haytham is almost entirely unknown in the Western intellectual tradition — a striking omission given his stature. Ask a reasonably educated person to name the founders of the scientific method and you’ll hear Bacon, Galileo, Descartes. Ibn al-Haytham, who was doing rigorous experimental work in optics, psychology, and epistemology five centuries earlier, barely registers.
The reasons are partly historical and partly cultural. The Book of Optics reached Europe through a Latin translation (De Aspectibus) in the 13th century and genuinely influenced Roger Bacon and later Kepler. But the transmission was fragmented — the ideas arrived stripped of their author, absorbed into a Western story that didn’t have a natural place for a 10th-century Arab polymath from Basra.
The irony is that many things we attribute to the Scientific Revolution — controlled experimentation, systematic doubt, the separation of observation from received authority — Ibn al-Haytham was practicing in Cairo while Europe was still largely working from Aristotle at second hand. He didn’t just theorize; he built apparatus, ran experiments, and revised his conclusions when the evidence demanded it. The camera obscura, the intromission theory of vision, quantitative analysis of refraction: all Ibn al-Haytham, all a half-millennium before Galileo.
Naming this project Alhazen is a small attempt at a correction. We honor the memory of a truly great scientist.
The Nile Project Legend
According to historical accounts, Ibn al-Haytham’s critical method emerged from extraordinary circumstances.
The Fatimid Caliph of Egypt, al-Hakim bi-Amr Allah, heard of Ibn al-Haytham’s engineering reputation and invited him to regulate the annual flooding of the Nile River—a matter of crucial importance for Egyptian agriculture.
Ibn al-Haytham proposed building a dam south of Aswan. This was remarkably prescient—the modern Aswan High Dam stands in almost exactly the location he identified.
But when Ibn al-Haytham traveled south to survey the site, he realized the scheme was impractical with the technology available in his era. The engineering challenges were insurmountable.
He had to return to Cairo and inform the Caliph that his grand plan would fail.
This was dangerous. Al-Hakim was notoriously volatile and violent—he had executed scholars and officials for less. According to various historical sources, Ibn al-Haytham feigned madness to escape punishment.
He was placed under house arrest, where he remained for roughly ten years until al-Hakim’s assassination in 1021.
During this confinement, Ibn al-Haytham produced his greatest works, including the Book of Optics.
Sometimes the most productive work happens under constraint.
Project Origins
Skillful-Alhazen is forked from CZI’s alhazen project, originally built at the Chan Zuckerberg Initiative to help researchers understand scientific literature at scale.
The original system used:
- LangChain for agent orchestration
- PostgreSQL for data storage
- Various LLM providers
This fork reimagines the architecture:
- Claude Code replaces LangChain (more capable, less complex)
- TypeDB replaces PostgreSQL (knowledge graph instead of relational DB)
- Skills replace notebooks (modular, reusable, documented)
The goal remains the same: AI-powered scientific knowledge engineering, embodying Alhazen’s philosophy of critical engagement with sources.
