Davos, St. Moritz, Pontresina and Flims are in Switzerland. These towns are important both in winter (for skiing) and in summer. Tourists also like the cities of Lucerne, Geneva, and ZÃ¼rich. In 2011 the pharmaceutical industry in Switzerland directly and indirectly employed about 135,000 people.
Mobius coils are not necessarily inherently safe. Don Croft said that the type of mobius coil he makes (single-knot mobius coil) is safe, provided one either puts a crystal in it or places a boundary wire around it. Otherwise it can cause undesirable energy phenomena. Also, even a passive mobius alone will have a + side and a minus side. 2  You want to make sure the + side faces toward the business end of the crystal. 3  Anyway, this magnet thing feels pretty impressive, if strong magnets are used. 4  I just did this with a stack of neodymium magnets.
Calcite is transparent to opaque and may occasionally show phosphorescence or fluorescence. A transparent variety called Iceland spar is used for optical purposes. Acute scalenohedral crystals are sometimes referred to as dogtooth spar while the rhombohedral form is sometimes referred to as nailhead spar. Single calcite crystals display an optical property called birefringence (double refraction).
