Problem: Mexico City is home to a number of orchestras offering season programs. These include the Mexico City Philharmonic, which performs at the Sala Ollin Yoliztli; the National Symphony Orchestra, whose home base is the Palacio de Bellas Artes (Palace of the Fine Arts), a masterpiece of art nouveau and art deco styles; the Philharmonic Orchestra of the National Autonomous University of Mexico (OFUNAM), and the Mineria Symphony Orchestra, both of which perform at the Sala Nezahualcoyotl, which was the first wrap-around concert hall in the Western Hemisphere when inaugurated in 1976. There are also many smaller ensembles that enrich the city's musical scene, including the Carlos Chavez Youth Symphony, the New World Orchestra (Orquesta del Nuevo Mundo), the National Polytechnical Symphony and the Bellas Artes Chamber Orchestra (Orquesta de Camara de Bellas Artes).
The Palace of Fine Arts hosts what main symphony?

Answer: National Symphony Orchestra

Problem: The work of David Hilbert and Max Planck was crucial to the foundation of modern physics, which Werner Heisenberg and Erwin Schrodinger developed further. They were preceded by such key physicists as Hermann von Helmholtz, Joseph von Fraunhofer, and Gabriel Daniel Fahrenheit, among others. Wilhelm Conrad Rontgen discovered X-rays, an accomplishment that made him the first winner of the Nobel Prize in Physics in 1901. The Walhalla temple for "laudable and distinguished Germans", features a number of scientists, and is located east of Regensburg, in Bavaria.
Who won the first Nobel Prize in Physics?

Answer: Wilhelm Conrad Rontgen

Problem: William Champion's brother, John, patented a process in 1758 for calcining zinc sulfide into an oxide usable in the retort process. Prior to this, only calamine could be used to produce zinc. In 1798, Johann Christian Ruberg improved on the smelting process by building the first horizontal retort smelter. Jean-Jacques Daniel Dony built a different kind of horizontal zinc smelter in Belgium, which processed even more zinc. Italian doctor Luigi Galvani discovered in 1780 that connecting the spinal cord of a freshly dissected frog to an iron rail attached by a brass hook caused the frog's leg to twitch. He incorrectly thought he had discovered an ability of nerves and muscles to create electricity and called the effect "animal electricity". The galvanic cell and the process of galvanization were both named for Luigi Galvani and these discoveries paved the way for electrical batteries, galvanization and cathodic protection.
What harmful things did the discoveries made by Galvani lead to?
