Question: What is the chemical formula of the mineral used by the inventor known as 'The Wizard of Menlo Park' in 1895?
Context: Jonesite is a mineral with the chemical formula Ba(K,Na)[TiAlSiO]*6HO.  This mineral is named after Francis Tucker Jones (1905–1993), who discovered the mineral while working as a Research Chemical Microscopist at Berkeley in CA.  Jonesite has diffraction symmetry of mmm, which implies an orthorhombic system with all three axes perpendicular to each other and the angles between each axis equal to 90 degrees.  In addition to symmetrical properties, Jonesite is a biaxial mineral with birefringence, which is a term to describe the difference between index of refraction.  Jonesite is anisotropic, meaning the speed of light changes through the mineral, so the mineral shows color when viewed in crossed polarized light under a microscope.  The mineral also has medium relief, which is a measure of how well the mineral stands out when viewed under a microscope in plane polarized light.  In addition to being one of the rarest minerals in the Benitoite Gem mine located in California, Jonesite also is the first titanosilicate mineral with a porous double-layered crystal structure.  This discovery is important because titanosilicate frameworks have industrial uses in energy companies and are used in containing radioactive waste. The Thomas Edison Center at Menlo Park, also known as the Menlo Park Museum / Edison Memorial Tower, is a memorial to inventor and businessman Thomas Alva Edison, located in the Menlo Park area of Edison, Middlesex County, New Jersey, United States.  The tower was dedicated on February 11, 1938, on what would have been the inventor's 91st birthday. Menlo Park Terrace is an unincorporated community located within Woodbridge Township in Middlesex County, New Jersey, United States.  It is located off U.S. Route 1 in between Menlo Park Mall and Woodbridge Center.  It is a residential suburban neighborhood with an ethnically diverse population, a fire station, and Menlo Park Terrace School #19, which services grades K-5 under the direction of Principal Margret Truppa.  Menlo Park Terrace is located off exit 130 off the Garden State Parkway, and can be seen along the parkway heading southbound. The Edison State Park is located in the Menlo Park section of Edison, New Jersey.  It covers a total area of 37 acres .  The park commemorates the site where the famous inventor Thomas Alva Edison had his Menlo Park laboratory.  In his laboratory, Edison invented over 600 inventions such as the incandescent electric light and the phonograph, the latter being the first object to record and play sound. Menlo Park is a city at the eastern edge of San Mateo County, in the San Francisco Bay Area of California, in the United States.  It is bordered by San Francisco Bay on the north and east; East Palo Alto, Palo Alto, and Stanford to the south; Atherton, North Fair Oaks, and Redwood City to the west.  Menlo Park is one of the most educated cities in the state of California and the United States, with nearly 70% of its residents having earned a degree.  Menlo Park had 32,026 inhabitants according to the 2010 United States Census. West Menlo Park is a census-designated place and an Unincorporated community in San Mateo County, California, located between the majority of City of Menlo Park, the Town of Atherton, the Sharon Heights neighborhood of Menlo Park and Stanford University (in Santa Clara County).  As of the 2010 census, the community had a population of 3,659. The Menlo Park City School District is a public school district in the San Francisco Bay Area, primarily serving the communities of Menlo Park and Atherton.  Through the Tinsley Voluntary Transfer Program the district allows students from Redwood City, East Palo Alto and eastern Menlo Park to attend MPCSD schools. Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman, who has been described as America's greatest inventor.  He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb.  Dubbed "The Wizard of Menlo Park", he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory. Campigliaite is a copper and manganese sulfate mineral with a chemical formula of CuMn(SO)(OH)·4HO.  It has a chemical formula and also a crystal structure similar to niedermayrite, with Cd(II) cation replacing by Mn(II).  The formation of campigliaite is related to the oxidation of sulfide minerals to form sulfate solutions with ilvaite associated with the presence of manganese.  Campigliaite is a rare secondary mineral formed when metallic sulfide skarn deposits are oxidized.  While there are several related associations, there is no abundant source for this mineral due to its rare process of formation.  Based on its crystallographic data and chemical formula, campigliaite is placed in the devillite group and considered the manganese analogue of devillite.  Campigliaite belongs to the copper oxysalt minerals as well followed by the subgroup M=M-T sheets.  The infinite sheet structures that campigliaite has are characterized by strongly bonded polyhedral sheets, which are linked in the third dimension by weaker hydrogen bonds. Scheelite is a calcium tungstate mineral with the chemical formula CaWO.  It is an important ore of tungsten (wolfram).  Well-formed crystals are sought by collectors and are occasionally fashioned into gemstones when suitably free of flaws.  Scheelite has been synthesized using the Czochralski process; the material produced may be used to imitate diamond, as a scintillator, or as a solid-state lasing medium.  It was also used in radium paint in the same fashion as was zinc sulphide, and Thomas Edison invented a fluoroscope with a calcium tungstate-coated screen, making the images six times brighter that those with barium platinocyanide; the latter chemical allowed Röntgen to discover X-rays in early November 1895.
Answer: CaWO
