コピペご苦労
そのコピペに
there is a method of predicting the value f(a) of a function f mapping the reals to the reals, based only on knowledge of f's values on the open interval (a – 1, a)
とありますけど?

あなたこれが間違いだと主張してるんですよね?
じゃあ出版社に間違い指摘したらいかがです?
鼻で笑われるでしょうけどw

なるほど
ありがとう
これ、謎のプロ数学者氏が好きそうな話題かもねw

えーと>>560より、関連含め引用下記
This book deals with the question of how successfully one can predict the value of an arbitrary function at one or more points of its domain based on some knowledge of its values at other points.
Topics range from hat problems that are accessible to everyone willing to think hard, to some advanced topics in set theory and infinitary combinatorics.

For example, there is a method of predicting the value f(a) of a function f mapping the reals to the reals, based only on knowledge of f's values on the open interval (a – 1, a), and for every such function the prediction is incorrect only on a countable set that is nowhere dense.
