First appearance of these milestone papers on photochemistry, as it was here the opinion ""that only the absorbed light rays are active in the production of chemical changes"", was expressed for the first time and ""thus, he formulated the importent basic law of photochemistry, which is named after him, ""the Grotthuss law of photochemical absorption"" (Eder ""Histo of Photography"" p. 166 ff.). The extracts as offered here, from ""Annalen"" were published before they appeared in the Annalen der Curländischen Gesellschaft für Litteratur und Kunst.""This importent Grutthussian thesis was in time so completely forgotten that John William Draper, two years after the inventionof the daguerreotype, discovered the same law and entirely independently of Grotthuss (1841). For a long time it was known as ""Draper's Law of absorption"" in ignorance of Grotthuss' priority....The four laws of Grotthuss (as formulated in the first paper offered) are....These laws... found little appreciation among his contemporaries...Still we must recognize the fact that the basic ideas which Grotthuss laid down in his photochemical theses were not far removed from the most modern views of physcal chemistry, since the chemical forces of affinity are essentially of an electrical nature"".(Eder opt.cit. p. 168).The volume contains other importent papers Macartney & Tilesius Beobachtungen über leuchtende Thiere"" (4 parts), Chladni, E.F.F.

First appearance of an importent paper in which Grove describes and depicts his invention - from 1839 - of the first FUEL CELL, which he named ""The Gas Voltaic Battery"", and where he applied his anticipation of the principle of ""Conservation of Energy"" to the decomposition of water. and to the ignition of the released gases.In 1846, Grove published ""On The Correlation of Physical Forces"" in which he anticipated the general theory of the conservation of energy that was more famously put forward in Hermann von Helmholtz' Über die Erhaltung der Kraft (On the Conservation of Force) published the following year.His 1846 Bakerian lecture relied heavily on his theory.(The paper offered).During the early 1960s, General Electric produced the fuel-cell-based electrical power system for NASA's Gemini and Apollo space capsules. General Electric used the principles found in the ""Bacon Cell"" as the basis of its design. Today, the Space Shuttle's electricity is provided by fuel cells, and the same fuel cells provide drinking water for the crew.NASA decided that using nuclear reactors was too high a risk, and using batteries or solar power was too bulky to use in space vehicles. NASA has funded more than 200 research contracts exploring fuel-cell technology, bringing the technology to a level now viable for the private sector

Summary While Northern and East Central Europe are often considered to have been peripheral parts of medieval Latin Christendom, they nevertheless embraced many of the same cultural impulses found in more central areas. Key among these was the way in which social elites, in the first centuries after the introduction of Christianity, recognized the potential to exploit the cult of saints as a way of legitimizing their own social standing. Taking this thematic focus as its starting point, this volume explores the intersection of religion, power, and the reception and development of new impulses from abroad within Northern and East Central Europe. It does so by comparing and contrasting cults that emerged locally with cults that were imported to the region. Through this comparative overview, the chapters of this volume not only contribute to a more nuanced understanding of these outlying regions, but also shed new light on Latin Christian Europe as a whole.
