REQUESTS AND WARNINGS
about files on the dropsite
contains some of the latest drafts of the Second Edition of the textbook
Exploring Black Holes: Introduction to General Relativity by authors
Edmund Bertschinger, Edwin F. Taylor, and John Archibald Wheeler, to
be published by Pearson Addison Wesley of San Francisco, CA, USA. We
would very much appreciate your comments, criticisms, and suggestions.
Please send these to Taylor at firstname.lastname@example.org Two requests and two
- REQUEST NUMBER ONE: Please include in your email the COMPLETE FILE
NAME of the file on which you are commenting. Files are replaced often,
and the only way we know what you are talking about is to know the
COMPLETE file name. At the top of every page is the file name of the
form FileNameYYMMDDv# For example, the file name Map080923v3 means "the
third version of the Map Project that was created on 23 September 2008."
- REQUEST NUMBER TWO: Please label each comment with the LINE NUMBER
or range of line numbers on which you are commenting. That pinpoints
the place in the text to which we should go to install your corrections
and improvements. Of course, line numbers get pushed around from one
draft to the next, so line numbers are almost useless if you do not
give us also the complete file name! (See request number one.)
- WARNING NUMBER ONE: These are drafts. Obviously errors remain. Don't
blame us; help us! You will also find new figures indicated and described
but not yet drawn and NOTES to ourselves (USUALLY IN CAPS) that remind
us of questions or future plans. Please feel free to give us your advice
and ideas on these unfinished items as well.
- WARNING NUMBER TWO: Edmund Bertschinger is Head of the Physics Department
at the Massachusetts Institute of Technology, so he is busy in many
ways. Taylor is often left to charge ahead with what he thinks Bertschinger
has in mind. Sometimes this turns out not to be what Bertschinger has
in mind. Most files on this website are a mix of competent and proposed
The first edition can be found on
this web site.
