Hi Rod:
Using time sent over telegraph wires allowed determining longitude much more accurately than was possible before because
time could be transferred more accurately than prior. But this also created a problem in setting clocks. In the late
1800s and early 1900s there were a lot of patent applications on ways to do this and a guy named Einstein who worked in
the Swiss patent office read pretty much all of them in his office. People were beginning to see what today we would
call relativistic differences but at that time they just saw problems. Note that Eisenstein never received a Nobel
prize because he was just a patent clerk, not a scientist.
A common misconception is that Newton was a physicist who figured out what gravity is. Not at all true. Newton was a
mathematician who invented mathematics to make "black box" calculations about gravity but had no clue how it worked.
More about this in the Richard Feynman lectures at Cornell "The.Character of Physical Law".

Thanks Sara,
A very interesting book. Haven't finished reading it but will.
It reminds me of a book that I once read about time.
Book indicated that when the telegraph lines were invented. This then allowed time to be accurate at the end of the
telegraph line. Which then allowed the location longitude to be accurately defined. And more places as the telegraph
lines were extended. And even more places when wireless was invented.
Time is very interesting.
John Harrison's Longitude watch also allowed the longitude to be determined more accurately at sea. The story of
Longitude and time.
Regards,
Roderick Wall.
At the end of the line in Australia.

Dear All,
The links were free to me and others, but perhaps we are somehow inside the
firewall. I don't understand what is going on, since I have not logged into
the Springer site.
Here is a link to my download of the book:https://www.dropbox.com/s/uly1qfaov3intr1/Science%20of%20Time%202016%20BOOK_978-3-319-59909-0.pdf?dl=0
I hope this will help.
Sara

For free? Not when I followed the links.
