Somewhat depends upon the intended audience but the following items come to mind and I'll finish with 2 references from which to pick more. The props chosen might also depend somewhat at to what "the presented philosophy of what time is" is.
Here's a few things that come to mind: Various calendars (Myan, Hebrew, Julian, Gregorian, etc. illustrating their significance <and making a joke or 2 about the "end of time" according to the myan long count coming soon) . Telescope/transit/sextant - translate where you are to when it is. Rubidium Oscilator (a cesium beam is probably a bit big to take along but a modern rubidium easily fits in a suitcase) WWV/WWVH audio recievers WWVB and gps recievers with display (time/frequency transfer methods & radio controlled clocks) finished and unfinished quartz crystals. marine chronometer pendulum (could be as simple as a mass on a string, variable length being nice as one can observe how the period changes with length <and with variation in g should you be able to arrange such ;) > ) heliometer pocket watch clepsydra (aka water clock) candles Hourglass sundial tally stick (used for the counting of days) Eric On Tue, Apr 3, 2012 at 10:59 AM, Rob Seaman <[email protected]> wrote: > > I'm giving a colloquium in a couple of weeks and would welcome suggestions > for neat timekeeping gizmos (borrowed or bought) to spark interest. > > Rob > > _______________________________________________ > LEAPSECS mailing list > [email protected] > http://six.pairlist.net/mailman/listinfo/leapsecs _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
