Wikipedia & me:[edit]

How I discovered Wikipedia, I do not remember. But from being a reader I slowly became a contributor. Although I don't work that much on Wikipedia I do see myself as a Wikipedian. I don't go searching on Wikipedia what I can edit next, I edit what I find and want to do. This means I add and mainly improve a lot of small things and only rarely I make large edits.

Union gunboats bombarding Confederate defenses
Union gunboats bombarding Confederate defenses

The Battle of Grand Gulf was fought on April 29, 1863, during the American Civil War. Union Army forces commanded by Ulysses S. Grant had failed several times to bypass or capture the Confederate-held city of Vicksburg, Mississippi. Grant decided to move his army south of Vicksburg, cross the Mississippi River, and then advance on the city. A Confederate division under John S. Bowen prepared defenses—Forts Wade and Cobun—at Grand Gulf, Mississippi. To clear the way for a Union crossing, seven ironclad warships from the Mississippi Squadron of the Union Navy commanded by Admiral David Dixon Porter bombarded the Confederate defenses at Grand Gulf. Union fire silenced Fort Wade, but the overall Confederate position held. Grant decided to cross the river elsewhere. The next day, Union forces crossed the river at Bruinsburg, Mississippi. The position at Grand Gulf was abandoned and became a Union supply point. The Grand Gulf battlefield is preserved in Grand Gulf Military State Park. (Full article...)


Sphalerite
Sphalerite is a sulfide mineral with the chemical formula (Zn,Fe)S. It is found in a variety of deposit types, and is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite, and fluorite. Sphalerite is an important ore of zinc, with around 95 percent of all primary zinc extracted from its ore. Due to its variable trace-element content, sphalerite is also an important source of several other metals such as cadmium, gallium, germanium and indium. The zinc in sphalerite is also used to produce brass. This sample was extracted in Creede, Colorado, and features black tetrahedral crystals of sphalerite up to 8 mm (0.31 in) in size, with minor chalcopyrite and calcite, in a 4.5 cm × 3.0 cm × 2.0 cm (1.77 in × 1.18 in × 0.79 in) matrix.
