- Dream Lake (Washington) (Wikipedia)
Dream Lake is a freshwater lake located on the southern slope of Dog Mountain in King County, Washington, United States. It is west of Otter Lake, part of the Alpine Lakes Wilderness. Big Creek, a tributary to the Taylor River, exits Dream Lake into a canyon that produces Big Creek Falls. Because of its proximity to Dog Mountain summit and the cirque of Rooster Mountain to the west, the lake is a popular area for hiking, swimming, and fishing and rainbow trout. Access to Dream Lake is provided through an unmaintained access trail that splits off the Snoqualmie Lake Trail.
- Electron hole (Wikipedia)
In physics, chemistry, and electronic engineering, an electron hole (often simply called a hole) is a quasiparticle denoting the lack of an electron at a position where one could exist in an atom or atomic lattice. Since in a normal atom or crystal lattice the negative charge of the electrons is balanced by the positive charge of the atomic nuclei, the absence of an electron leaves a net positive charge at the hole’s location.
