Hi there
Just thought this little snippet might be of interest to some budding physicists here -- some of the crazy ideas in the past of how people attempted to solve the issue of LONGITUDE for navigation in days gone by.

I always like looking at this sort of stuff when things get very quiet in an office -- Aug 1 is always an incredibly quiet day -- I wonder why I even bother to turn up as most people have already gone on their summer holidays (Northern Hemisphere). !!

Enjoy. !!
