This website is an attempt to describe the history of the development
of electrical horology that eventually led to the Synchronome-Shortt free
pendulum. It is certainly not complete and many parts of this evolution are
omitted for the sake of simplicity. The emphasis is put on technical details
and for that reason many animations are shown.
The use of animations is a powerful tool to show how
things work in detail. Words can hardly describe what an animation will show
in an instant.
By putting your cursor over an image a different image may appear or a small
animation will run. Clicking on the animation
sign will open full size animations. Some sound effects have been added to
create a livelier atmosphere.
In
order to view these animations Adobe's
Shockwave Player needs to be installed on your computer. So, if you don't
see little animations at the top left and bottom of this page go to www.Adobe.com
where you can download this Shockwave Player free of charge.
Many more animations than shown on
this website can be viewed by obtaining a disc I created.
This disc contains over 250 animations of electric clock systems.
Please see page 11 for
more details. On the last pages I have placed
some simple animated gif's for use in email or website.
