Willebrord SnelliusWillebrord Snellius at the Leiden Digital Family Tree.Eerste Nederlandse Systematisch Ingerichte Encyclopaedie (gebore as Willebrord Snel van Royen)Encarta Winkler Prins, Grote Oosthoek, Eerste Nederlandse Systematisch Ingerichte Encyclopaedie (13 Junie 1580Sometimes mistakenly noted as 1590 or 1591; Cf. .30 Oktober 1626) was 'n Nederlandse sterrekundige en wiskundige. Sy naam is gekoppel aan die wet van refraksie as Snell se Wet.For a reconstruction of this discovery see Hentschel 2001. It is now known that this law was already known to Ibn Sahl in 984. The same law was also investigated by Ptolemy and in the Middle Ages by Witelo, but due to lack of adequate mathematical instruments (i.e. trigonometric functions) their results were saved as tables, not functions.
'n Krater op die Maan, Snellius is na hom vernoem. Die Nederlandse Vloot het drie skepe na hom vernoem insluitende die bestaande HNLMS Snellius (A802).
