Plasma Ball

Here are some pictures taken of a plasma ball at the Adventure Science Center in Nashville, Tennessee. I must say that have some very nice science exhibits using some cool display technologies in the building. Most of the science center is aimed at small to grade school level children with the exception of the astronomy area.  Highly recommended if you have children in this age group or if you are interested in astronomy .

Nashville City Cemetery

Over the Thanksgiving holiday I visited Nashville, Tennessee. Some spare time became available, so I made a quick visit to the cemetery in Nashville that is home to the grave of Dr. Gerard Troost. Dr. Troost is tied to Louisville because his mineral/fossil collection is stored at the Louisville Science Center (former Natural History Museum of Louisville founded in 1871).  Dr. Troost was also active in the New Harmony, Indiana utopian community in the early 1800s.  New Harmony is about 131 miles driving distance from Louisville, Kentucky.

The Nashville City Cemetery Association should be commended for their work in maintaining and cleaning up this cemetery (established 1822).  I found it to be a clean and peaciful place that is the final resting place for a number of past residents of the city.  The website is excellent and the records there helped me find Dr. Troost grave in section 29.1 near the cross section of Pine Avenue and Maple Avenue (inside the cemetery).  The 1909 records show the grave at Section M-29, Lot 25 belonging to Mary Troost.

The grave of Gerard Troost, M.D.; Ph. M. born March 15, 1776 (Bois-le-Duc, Holland) and died August 14, 1850 (Nashville, Tenneessee).  He was a Professor of Chemistry and Geology at University of Nashville, 1828-1850.  I think that university was merged into what is now Vanderbilt University.

Apparently, this grave marker is not the original and might be from 1905-1906.  According to The American Geologist A Monthly Journal of Geology and Allied Sciences, Editor N.H. Winchell, Volume XXXV, January to June 1905.  The article is in the February 1905 section entitled Gerard Troost by L.C. Glenn, Nashville, Tenn. pages 72-94.

To quote from the article on pages 89-90, "He sleeps in an unmarked and neglected grave in an obscure corner of the old city cemetery of Nashville.  The State will be asked at the coming session of the legislature to place an appropriate marker over his grave and thus rescue from oblivion the last resting place of one who gave much of his time and skill to the service of the State in making known the existence or extent of natural resources whose later development has brought wealth and prosperity to their fortunate possessors.  The portrait herewith reproduced is from a portrait in oil belonging to the Tennessee Historical Society."

I took this picture of the grave of Henry Langford, a War of 1812 veteran.
