He was a critical scholar of alchemical literature, and of Islamic science, raising many issues on attributions and sources of the texts, and providing translations. The range of his studies was wide, including the ''Emerald Tablet'', a basic hermetic text. From 1924 he headed an institute in Heidelberg, where he has been a student.

Emerald Tablet
The Emerald Tablet, also known as the Smaragdine Table or the ''Tabula Smaragdina'', is a compact and cryptic text traditionally attributed to the legendary Hellenistic period, Hellenistic figure Hermes Trismegistus. The earliest known versions are four Arabic recensions preserved in mystical and alchemical treatises between the 8th and 10th centuries CE—chiefly the ''Sirr al-khaliqa, Secret of Creation'' () and the ''Secretum Secretorum, Secret of Secrets'' (). It was often accompanied by a frame story about the discovery of an emerald tablet in Hermes' tomb. From the 12th century onward, Latin translations—most notably the widespread so-called ''vulgate''—introduced the text to Europe, where it attracted great scholarly interest. Medieval commentators such as Ortolanus, Hortulanus interpreted it as a "foundational text" of alchemical instructions for producing the philosopher's stone and Chrysopoeia, making gold. During the Renaissance, interpreters increasingly read ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From The Grand Duchy Of Baden
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ernst Ruska
Ernst August Friedrich Ruska (; 25 December 1906 – 27 May 1988) was a German physicist who won the Nobel Prize in Physics in 1986 for his work in electron optics, including the design of the first electron microscope. Life and career Ernst Ruska was born in Heidelberg, Germany. He was educated at the Technical University of Munich from 1925 to 1927 and then entered ''Technische Hochschule Berlin'' (now Technische Universität Berlin), where he posited that microscopes using electrons, with wavelengths 1000 times shorter than those of light, could provide a more detailed picture of an object than a microscope utilizing light, in which magnification is limited by the size of the wavelengths. In 1931, he demonstrated that a magnetic coil could act as an electron lens, and used several coils in a series to build the first electron microscope in 1933. After completing his PhD in 1933, Ruska continued to work in the field of electron optics, first at Fernseh AG in Berlin-Zehlendo ...
