 This para isn't acceptable: 

 : Unfortunately, UNESCO did not check the credentials of its partner, who are engineers, but not historians. Ibn al-Haytham did not lay the foundations of the present day, but contributed with significant work to methods, theories and observations that were developed and made in Antiquity and shared by many scholars, whatever their ethnicity or religious affiliation, in Islamicate and Christian societies of the Middle Ages and the early modern period. Hence, Ibn al-Haytham certainly deserves our respect and appreciation as one of the great scholars of the 10th century and worthy to be mentioned with praise in all our modern cultures across the globe,  in schoolbooks, newspapers, the TV, the Internet or other media. But we should not present him as the inventor of modern optics or today's scientific methods, which are neither one nor the same even as in the 19th century. 

 It may or may not be true, but without any sources its just editorial interpolation
