- Schrödinger’s cat (Wikipedia)
In quantum mechanics, Schrödinger’s cat is a thought experiment concerning quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead, while it is unobserved in a closed box, as a result of its fate being linked to a random subatomic event that may or may not occur. This experiment viewed this way is described as a paradox. This thought experiment was devised by physicist Erwin Schrödinger in 1935 in a discussion with Albert Einstein to illustrate what Schrödinger saw as the problems of the Copenhagen interpretation of quantum mechanics.

- Paradise Valley Conservation Area (wta.org)
This wild wood started out as a working farm and timber producing homestead over one hundred years ago. It became part of the Snohomish County Park system in 2000, and now is in the process of returning to the wild state it once was. We hikers can watch this dynamic landscape by following the many trails that run through it. The trails are all well signed and a map can be printed or downloaded to your smartphone from the Snohomish County Parks website. Hike the perimeter trails for a good sampling of the area and a nice hike of about 5 miles.
