Errata
P. 82, subsection Planet with constant density. Replace in first line: "(3.19)" → "(3.31)" Replace twice in eq. (6.37): "2/5"→ "3/5" In example 6.4.1: multiply all numbers by 3/2. 

P. 83, subsection Field Energy
Density. Insert in integral at the end of unnumbered equation below (6.38): "dV". Insert at last line: "..., one immediately..." → "... for r<a and M_0 for r>a, one immediately..." 

Remove on p. 87, eq. (7.4) the
middle expression between equals signs "=  g\cdot x =" → "=" 

Replace p. 87, Kepler microbiography, line 1 "...(15801635)..." → "...(15711630)..." 

Insert p. 100, next to last
paragraph, line 4 from below "... 0, whereas mercury..." → "...0 [80], whereas mercury..." Add following sentence to the end of the paragraph "This is especially true for the waterairglass contact angle, where nearly every value below 90 degrees is found in the literature. In the following `water' and `mercury' should only be taken as examples of highly wetting and moderately nonwetting fluids." 

Replace p. 113 next to last
paragraph, line 2 from below "...(i.e. several megabars),..." → "...(i. e. tens of kilobars),..." 

Replace p. 145 problem 11.8 third
line "...=α." → "...=α/2." Problem 11.8 should in fact be placed in chapter 10 (see new answer). 

Replace p. 194 example 15.3.1 "1000 kg/m^2" → "1000 kg/m^3" 

Page 202, subsection "The
cosmological constant". The nonrelativistic physics argument leading up to this equation (15.61) is hard to justify, and the whole subsection may eventually have to be removed. Thanks to Dr. C. W. Palmer for an enlightening discussion. 

Replace p. 236 third paragraph first line,
"... requires the pressure to be ..." → "... requires the stress vector to be ..." See additional material on pressure discontinuities. 

Replace p. 260 third line below eq. (18.67) "... are orthogonal to the velocity." → "... are parallel to the velocity." 

Replace p. 268 first paragraph 5th line "... may for example eliminate ..." → "... may also eliminate ..." 

Replace p. 281 line before end of first paragraph "...there will appear three further fictitious..." → "...there will appear two further fictitious..." See also the replacement of problem 20.3. 

Replace p. 354, figure 24.9 caption second line "... U = 12, 15, 20 ..." → "... U = 12, 15,18..." 

Insert p. 382 first line "... positions z=naib of ..."→ "... positions z=2naib of ..." 

Replace p. 397 bottom marginal figure caption line 3 "... towards the left and ..."→ "... towards the right and ..." 

Insert footnote p. 460 just above
eq. (29.67) "This formula appears to be valid for all values of the angle of attack, but that is of course nonsense. It can only be used as long as the flow obeys the Kutta condition. At a fairly small angle of attack, the boundary layers will detach and invalidate the whole calculation, and at the stall angle the flow changes completely character. " 

Replace p. 4767
Wind chill estimate,
second paragraph. 

Replace p. 483 line above Example 31.1.1 "... (3.13) ..." → "... (31.3). .."
