== Delete Engineering? == 

 I've deleted a lot of the claims in the Engineering section, but I'm tempted to delete the whole lot. The only source cited I can't check and was listed with a "Failed verification" anyway. The reference was: "Mariam Rozhanskaya and I. S. Levinova (1996), "Statics", in Roshdi Rashed, ed., Encyclopedia of the History of Arabic Science, Vol. 2, p. 614-642 [633]. Routledge, London and New York." Can anyone check that, or provide another source to back up the claims in this section? I can't even verify that Mi'yar al-'aql existed.
