Hi all:
Just wanted to offer much encouragement to those of you who put this forum together. Needham's book is such a gem, it's great to see people actively pursuing it in this way.
I am curious if anybody is in touch with the author, so that use can be eventually made of all the corrections accumulating here. This seems like an excellent way to help improve an already almost impeccably edited work. I have never seen a so beautifully written math/science that also comes with such a low rate of errata as to be considered almost non-existent! And now there is a tool to make it even more so . . .
Very nice indeed!

Hi
Thanks for the compliments! Glad you like the forum.
I have tried to contact the author via his email which is published on line at his University's site, but for whatever reason he does not reply. This book was first published a long time ago (1997) and most of the errors in the first editions have been corrected as you say. I guess the author has moved on. There has been a recent reprinting of the book, but with no correction of errors.
Publishing them on this forum is useful as you say, but I guess not everyone finds the forum.
Thanks again
Vasco

Since I think the 2012 printing I have is the most recent, it is good to know that it the same as the previous one from 2000.
Editing a book of this nature that has reached the almost flawless point it is in now has got to be an excruciatingly painful endeavor, so I can understand that Needham might wish to just leave it as it is.
Having read and gone through every exercise through almost the end of chapter 9 (still working on its exercises), I can say that the few errors left up to that point are of no importance. In fact I personally appreciate struggling with the occasional error, as the effort generally leaves me with a better understanding, so I think perhaps the few remaining blemishes actually add to the beauty of the work.
That said, it is certainly very nice to have a forum like this to bounce ideas around with others whenever one is seriously in need of some feedback. So again thanks for putting this together.
Cheers, Nick

Nick,
It was Vasco who put it together. I ran across it in its previous form just has you have found this one on freeforums.net, and I have been doing as you are doing --- going through all the exercises in order. I'm quite sure I would not have been able to do many of them on my own.

I wonder in the same spirit of this site and forum, whether someone will attempt to read and explain a different complex Analysis book—Visual complex Functions with phase portraits—Elias Wegert. Mathematica 10 can be helpful for some plots of phase. This is a fab book, and in someways similar to the one this forum is dedicated to.

John,
It is a very appropriate proposal, which I hope will be taken up by someone. And thank you for calling our attention to the Wegert's Visual Complex Functions. I am going to have a look at it to see what one can say with the color phase portraits.

Hi John
Good idea. Why not start a forum yourself?

Hi John
By the way, does the book have exercises?

The author's another book "visual differential geometry and forms" is also awesome.
