Correcting Misconceptions

The Arab polymaths corrected a great deal of Classcial misconceptions, e.g. the Greek idea that light is emitted from the eye. The 10th century physicist al-Haytham (Latinised to Alhazen) correctly stated that light bounces off an object in straight lines before striking the eye. He developed for first camera obscura – which centuries later enabled photography. Alhazen first devised the ‘method of proof’ too, stating that theories had to be verified in practice, a key element from modern science practice, which was missing from the classical world. Abbasid scientists also introduced what we would call peer review and academic citations, unknown before their time.
