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
