    Re: Navigation by the Moon

    Frank,
    Thanks for editing my message, but frankly speaking I do not see why there was a need to do this.
    I compared the result with the original copy, and the main difference is that 
    the right edges of the lines are aligned.
    I do not see why this is important.
    
    The Stone age software that I am using is called Microsoft Outlook, Light 
    version, and this is the standard e-mail
    software in my university. 
    
    I also wanted to post a scan of 2 pages of the book, but then recalled how 
    angry you were when I suggested posting 
    some pirated text on this site:-)
    
    Returning to the essence of the story, it was already discussed in this site 
    that some well trained navigators can estimate
    angles by eye with high accuracy. Another matter is that they were able to 
    compute without any tables he azimuth of the Moon
    at a given time (by watch). Perhaps it is assumed that they practiced Lunars 
    systematically:-) and happened to remember the 
    difference in hour angle between the Sun and the Moon from some recent observations?
    
    Alex.

    Since I had to do quite a lot of manual editing to get Alex's message in 
    proper form (thanks to stone-age email software on the user's end! :) ), I 
    acquired copies of the original pages of the book. Here are those pages for 
    context in case anyone wants a little more for this story. This is fiction, 
    of course, but if you want to think through whether it makes any sense in 
    navigation terms, it may help to have this context.
