Time Marches On Mystery Cache

This cache has been archived.

bigcall: My apologies to those trying who have been patiently waiting for the tours to restart. I made a decision to leave the cache active since some cachers have still been able to access the grounds. Unfortunately it appears that it's not going to be "open" as intended anytime soon.

So with a heavy heart I think it's time to move on....

Geocache Description:

Not an overly difficult cache, but a little research is required to find out where to go. Once the proper location is found a free tour is available (and is necessary, reservations are required) to answer the questions.

The listed coordinates are not the location of this cache although they may aid you in finding the ultimate destination.

As the name suggests, this cache has a historical flavor reflecting an old to new theme.

First a question on the old ways: The constant rate of travel of the mean sun makes possible conversions of arc to time. If there are 24 hours in every mean solar day and 360 degrees in the circumference of the earth how long (in seconds) does it take for the sun to traverse 1 degree of arc (longitude)?

Second question relates to the newer ways: Universal Coordinated Time (UTC) is currently based on the frequency of vibration of a certain element. What is the isotope associated with this radioactive element?

Using these answers you can now determine the coordinates for the entrance to the final cache.

Using the answer to the first question, take the first digit and add it to the minutes of the latitude of the coordinates listed above. Now take the entire answer to the first question and multiply it by 2 and then add 69. Subtract this result from the decimal portion of the listed latitude. For example if you found the answer to be 120 seconds then the latitude would be N38° 54.385.

Using the answer to the second question, multiply it by 6 and then add 46. Add this result to the decimal portion of the longitude of the coordinates listed above. For example if you found the isotope to be 96 then the longitude would be W077° 03.718.

These new coordinates will get you to the entrance of the virtual cache. In order to be able to access this area you must now determine where this is (easiest if done online - it should be obvious) and sign up for a tour (which is the only way to get past the gate). It's free and they are currently given every other Monday starting at 8:30 PM. You can sign up via the location's web site under public affairs or call.

To claim credit for this cache e-mail me the answer to the following questions:

1. In the foyer of one of the buildings on the tour is a rather large instrument that was built in 1897 and was in use until 1995. What is it?

2. In the Library a display case contains several very old books, the largest one, placed in the middle of the display contains several engravings. Who was the author?

This is intended to be a fairly difficult cache to complete due to the advance preparations. It will most likely take a bit longer to complete than the average virtual cache, but the experience will be worth the effort. If you have any questions/difficulties along the way or just want to confirm anything just fire me a note.

Good luck and have fun!
