Note #15043

My hardware engineering is a little rusty, @ComputerHistory, but wouldn’t signals propogate along this copper cable at “only” somewhere between 0.64c and 0.95c, not 1c as you claim?

Exhibit of early transatlantic telegraph cable with message implying that it enabled "speed of light" communications.

09:56 Excellent cache in a great location. The hint was very helpful as even the small number of muggles around this early on was enough to require some stealth… and a useful TOTT – my phone, set to record video and held nonchalantly in the direction of the hide – helped too! Greetings from Oxford, UK, and TFTC!

The Elves may have left this place… but the geocache remains! Very easy find, and a satisfying conclusion to the series. Thanks for setting up/maintaining it, and greetings from Oxford, UK.
