Dear Mr. Körner, Sehr geehrter Herr Michael Basler,

I have read the book "Mathematisches Denken" and have found the following errata:

1. pp. 23-24: The paragraph "Snow war gerade dabei ..." is on both page 23 and page 24.

2. p. 50, line 16: If you insert the word "für" after "einem kurzen Zeitraum", the text is more comprehensible.

3. p. 73, lines 13-14: You should delete the words "Quellen, radioaktive".

4. p. 79: You should delete the word "senkrecht".

5. p. 93, line 6 from bottom: replace "i <> i" by "i <> j"

6. p. 93, line 4 from bottom: replace "<= n - 1)" by "<= n"

7. p. 94, line 11 from bottom: the index should be "m - n + i + 1" instead of "m - n + i"

8. p. 94, line 9 from bottom: delete "a_(m-n),"

9. p. 126, line 3 from bottom: replace "wächst" by "ist"

10. p.158, footnote: replace "bLicht" by "Licht"

11. p. 184, line 13: insert "pro Zeiteinheit" after "P(v)"

12. p. 214, line 2 from bottom:

x0' = gamma (u) x0 + (gamma (u) (U - u) u x0) / (1 - uU)

y0' = y0 + uVx0 / (1 - uU)

z0' = z0 + uWx0 / (1 - uU)

13. p. 240, under the two graphs: replace "root(2)" by "root(2)^(-1)"

14. p. 241, line 6: replace ">= x(r - 1)" by ">= (r - 1)"

15. p. 243, lines 6 and 9: replace "(..., f((r - 1)b/N +/- |B_r| (b/N)^2))" by "(..., f((r - 1)b/N) +/- |B_r| (b/N)^2)"

(the brackets are misplaced)

16. p. 247, line 6: delete "<= B b^3 N^(-2)" (I am not quite sure here.)

17. p. 257, line 6: the first two terms of the sum are "2^(-N-2)" and "2^(-N-3)" instead of "2^(-N)" and "2^(-N-1)"

18. p. 258, line 4 from bottom: replace "t - r 8^(-n)" by "-t + r 8^(-n)"

19. p. 258, line 2 from bottom: replace "2^(-n) / 3" by "2^(-n) / 6"

20. p. 264, line 8 from bottom: replace "t <= 0 " by "t < 0" (definitions should be unambiguous; of course, I know that in this case, it doesn't really matter)

21. p. 265, line 12: replace "E (...) (...)" by "E ((...) (...))"

22. p. 303, line 13: replace "zweiten" by "zweite"

23. p. 313, line 3 from bottom: insert "a mit" after "gleich"

24. p. 332, paragraph "Auf der ... zu lassen.": either a left bracket is missing or you should delete the right bracket at the end of the paragraphh

25. p. 341, line 5 from bottom: exchange "a_(n-2)" and "a_n"

26. p. 344: (I am not sure here.)

- line 1: replace "SCHRITT 1" by "SCHRITT 0"

- lines 17-18: replace "nach dem n." by "vor dem (n+1)."

- line 19: the bracket is at the wrong place

- line 20: replace "(n-1)." by "(n+2)."

27. p. 361, line 7 from bottom: exchange "Flußzahl" and "Schnittzahl"

28. p. 363, line 21: replace "i_(s-1)" by "i(s-1)"

29. p. 364, line 5: replace "Da i streng" by "Da u streng"

30. p. 365, diagram (e): replace one of the "3"s by a "2" and one of the "1"s by a "0" (Here, I am not sure.)

31. p. 367, line 14: the index of c should be "i(2n + 1)" instead of "i2n + 1"

32. p. 367, line 15: replace "1 <= j <= n" by "1 <= i <= n" and "n+1 <= i <= 2n" by "n+1 <= j <= 2n"

33. p. 367, line 22: replace the inequality by "|{j in {n+1,...,2n} | there is an i in S: c_(ij) = 1}| >= k"

34. p. 373 diagram: replace "10p+10" by "p+10" on line segment XY

35. p. 487, line 4: "b" should be capitalized

36. p. 535, the line before the exercise: replace "berühmten" by "berühmter"

37. p. 658, line 18: "vergnügen" should be capitalized
