Whatever was pointed out in the comments after October 2010 is still there, from what I’ve seen. If you had any specific thing in mind I can check

Hi, can you check if in the 7nth printing the few errata left have been fixed? Thanks

I have just purchased the 7nth printing. On p.14; 2nd column; equation no.10 was meant to define the prime numbers, however I believe it erroneously includes 1 in the definition. I think there might be an implicit assumption that a!=b; but as it stands 1 satisfy the definition.

I looked at the comments, but I did not see anyone else mentioning this.

Thanks for a wonderful, wonderful book!

I bought the Kindle edition and am very happy with it. The equations are easy to read for me. Though they don’t scale with the text because they are graphic images, which does look weird when they are in line ath symbols

I would love to see the many cross references be hyper links in a future edition.

Any news on the 7th printing? I’ve found the 6th in a local bookstore but if the 7th will fix the last erratas i might wait for it. Thanks!

Thanks for an excellent book. I have got many insights and much pleasure from it so far. I have the print book and am planning to get the Kindle edition too because it is hard to travel with the hardcopy, it is so big!

I am wondering if there is a plan to update the Kindle edition to make the many cross references into hyperlinks. And also to make the equations easier to read (I read on the Amazon review that they are faint graphics that can not be enlarged on the Kindle rather than LaTex fonts that scale).

Is the 6th printing still the most update edition available or the 7th is already out? Thanks

i couldn’t get an answer from Amazon either about which print they currently carry. Can anyone who has ordered the print book from Amazon recently confirm that they received the 6th printing?

34.1 line 9 should be f(x+h) = f(x)+mh+E(h) instead of g(x+h)=… because g is the approximation of f.

My mistake then, English isn’t my first language and that sentence didn’t “sound right” first time i red it. BTW, the book is amazing

“while away” is a perfectly good idiom in the US … I don’t see a problem with that sentence as it is in the PCM.

I’m not sure I see the problem, unless “while away” is an English idiom that doesn’t exist in the US.

By: SHK

In the 6th printing:
page 260.1 line -16 “you might like to while away a few..”
i guess should be “you might like to walk away a few..”

Minor typo in the 6th printing:
306.1 line 19 (equation mid-page)
F(t) should be F(s)

This book is so useful for what I am doing – many thanks to you and the team.

Hi,

In page 123, right column, line 27-31.
I have checked Cauchy’s Calcul Infinitesimal, 1823. I think when Cauchy defined definite integral, he assumed the function to be continuous, and he partition the interval between x_0 and X with a set of points x_1, x_2,…,x_n-1 where these points are either always increase or always decrease between x_0, X. I think he did not assume the fuction to be increasing or decreasing in each of the subintervals. I think he only assumed those points that divide the interval are monotonic.
Please let me know if I am wrong. Thanks.

On page 681, the ABC conjecture, it states that a,b,and c are coprime, but I thought the condition for the conjecture is that a and b are coprime. If all 3 must be coprime, then are they also supposed to be pairwise coprime?

In 6th printing, 43.2 line -13 says “where I is the 4×4 identity matrix”, while there is no I in the equation preceding it.

Many thanks for your info, amazon.com helpdesk didn’t know anything about which versions they stock, you’re response has been very useful, i guess it’s finally time to buy the book

From what PUP told me, it’s likely all of Amazon.com’s stock is the 6th printing. Their representative (who’s also mentioned by name in the book’s preface) told me the corrected printing was done in response to low stock. So whereas it’s not guaranteed all of Amazon.com’s inventory is the corrected 6th printing, I’d say it’s very likely. I ordered from them two weeks ago and did receive the 6th printing.

Many thanks for that information, it was exactly the kind of response I was hoping for when I posted my comment.

So i can order PCM from amazon.com and i’ll get the 6th from now on? Or it depends on stock’s level of previous printings? Thanks for the infos

By: Felix Chen

Felix Chen — Tue, 20 Apr 2010 13:17:56 +0000

Yes, the 6th printing is in stock at Amazon.com. I got mine several weeks ago.

‘Hit or miss’ is indeed correct wrt Amazon. I attempted to find out if they have the sixth printing in stock, but they were unable to tell me.
