The shop seemed to be full of all manner of curious things - - but the oddest part of it all was , that whenever she looked hard at any shelf , to make out exactly what it had on it , that particular shelf was always quite empty : though the others round it were crowded as full as they could hold . To answer this questions , I would first have to define who the reading public was at the time ( a very tricky proposition ) and then try to get a sense of exactly what it was like to read one particular book , the Orlando Furioso in that period . After 1945 , a very few people knew that Turing had done something important for the war effort but nobody knew exactly what it was , because he still was n't allowed to allude to it . Clearly he disdained me for my failure to blindly embrace and embody something , as though I would know exactly what it was without our ever having spoken , and in fact he was right : I knew precisely what it was . And it may be that from the ADA standpoint , readily-achievable still means exactly what it did , and still functions exactly as it did when the department of Justice defined it in 1991 . I did not know at that time exactly what it was going to be , but they just told me that it was n't ready .
