Diad saman ya panaon, dakel so oras to parad arum ni ya labay ton gawaen legan ya akakulong lapud say amta ra et natatapis.

Nen nibulos lay Alhazen, nisulat to lay dakel ya kabiangan na pitoran volume na Book of Optics, ya ipapasen a “sakey ed saray sankaimportantian ya libro diad history na physics.” Diad satan ya libro et impaliwawa to ray eksperimento to tungkol ed liwawa, kaiba lay no panon ya mankakapiga so liwawa ed nanduruman kolor to, no panon ya ontama tan ompuktal ed salming so liwawa, tan no panon itan ya onkurba ed saray tamaan to. Inaral to met so nanduruman parte na mata,  no panon itan ya onggagana, tan panon ya nabidbir na mata iray nanenengneng to.
