2. Atoms

Author(s):  
Geoff Cottrell

‘Atoms’ describes how humans discovered that the world is composed of atoms, even though they are invisible to the unaided eye. Starting with the prescient ideas of the Ancient Greeks 2,500 years ago there were, by the time of the Enlightenment, three ideas for a definition of matter: all matter is made of atoms, atoms take up space, and atoms have mass. The concept of atoms became more firmly rooted with the chemical experiments of the 19th century, but it was not until Albert Einstein’s interpretation of Brownian motion (the random jiggling of tiny dust particles) in 1905, that any last objections to the atomic hypothesis were finally quashed.

Pētījumā aplūkots privātdocenta statuss, kas pasaulē tika ieviests 18. gadsimtā un, sākot no 19. gadsimta otrās puses līdz Otrā pasaules kara beigām, pastāvēja arī Latvijā. Privātdocenta statuss salīdzināts ar citu pasaules valstu, galvenokārt vācu tipa universitātēm. Jēdzienu «venia legendi» un «privātdocents» skaidrojumi ar piemēriem no Rīgas Politehnikuma (RP) mācībspēku darbības atspoguļo šos jēdzienus no dažādiem aspektiem, lai 21. gadsimtā būtu saprotams to lietojums iepriekšējos gadsimtos. Autors pētījumam izmantojis arhīvu dokumentus un bibliotēku krājumus, balstoties ne tikai Latvijas, bet arī Krievijas, Vācijas un citu valstu zinātnieku atziņās. The study examines the status of a private docent, the academic position which was introduced across the world in the 18th century and which also existed in Latvia from the second half of the 19th century until the end of World War II. The status of the private docent as it used to be understood in Latvia is compared with other countries, mainly considering German-type universities. Definition of the terms «venia legendi» and «private docent» providing examples of academic activity of the lecturers of Riga Polytechnicum (RP) allow considering these concepts from various perspectives in order to make their meaning and usage in the previous centuries transparent for the users in the 21st century. Conducting the present research, the author has used archival documents and library collections, the theoretical framework includes the findings of not only the Latvian scientists, but also researchers from Russia, Germany and other countries.

Brazil received the largest number of enslaved Africans in the countries in the Americas. Of the 12.5 million men and women taken captive in Africa, about 5.5 million (44 percent) were sent to Brazil, which became one of the main slaveholding areas in the world. The enslavement of Africans and their descendants persisted in that country for more than three centuries and permeated all aspects of life. There was no work in which slave labor was not used, whether in the fields or in towns and cities throughout Brazil’s vast territory. The wealth produced by the exploitation of sugar cane, coffee, and the extraction of gold and diamonds relied primarily on the work of enslaved Africans. Brazil was built on the backs of Blacks. If the work of enslaved Africans and their descendants marked the building of wealth in that country, the struggles they waged over the centuries were also part of Brazilian history. The enslaved resisted the world conceived by their masters in many ways: by sabotaging the production of goods, slowing the pace of work, escaping, forming quilombos (maroon communities), killing masters and overseers, and planning slave revolts. These various forms of resistance coexisted during over three centuries of slavery in Brazil, but above all in the 19th century, when most of the collective slave revolts occurred. This does not mean that there were no uprisings before that time, but the accelerated arrival of Africans in the 19th century and the dissemination of several revolutionary ideologies (such as Islamism and the ideas of equality and freedom arising from the Enlightenment) created a favorable context for the outbreak of mass revolts. It was in the 1800s, specifically in 1835, that Brazil witnessed the largest urban uprising of enslaved individuals in the Americas when the Revolt of the Malês erupted in the streets of Salvador, Bahia.

Kasimir Malewitschs suprematistische Hauptwerke ›Schwarzes Quadrat‹, ›Schwarzer Kreis‹ und ›Schwarzes Kreuz‹ von 1915 setzen sich aus schwarzen Formen auf weißem Grund zusammen. Der Typus des Schwarzweißbildes weist überraschende Parallelen zu den bildlichen Wahrnehmungsinstrumenten auf, die vom ausgehenden 18. bis Anfang des 20. Jahrhunderts in den Experimenten der Farbenlehre, physiologischen Optik und Psychologie verwendet worden sind. Die vorliegende Studie untersucht diese Parallelen in drei Schritten: Zunächst erfolgt eine allgemeine Charakterisierung des Schwarzweißbildes mit Hilfe des Kontrastbegriffs von Edmund Husserl. Des weiteren wird die Entstehung und Funktion des schwarzweißen Kontrastbildes in den Wissenschaften des 19. Jahrhunderts typologisch herausgearbeitet. Unter Berücksichtigung des Wissensbegriffs von Max Scheler wird abschließend die Spezifik des Wissens eruiert, das die Schwarzweißbilder sowohl in der Malerei Malewitschs als auch in den genannten Wissenschaften generieren. Malevich’s main Suprematist works, such as ›Black Square‹, ›Black Circle‹, and ›Black Cross‹ from 1915, consist of black shapes on white ground. Surprisingly this series of shapes strongly resembles scientific black-and-white images used for research on colour theory, physiological optics, and psychology throughout the 19th century. This paper examines the parallels between Malevich’s paintings and the scientific drawings in three steps: It first characterizes black-and-white images in general, using Edmund Husserl’s definition of the term ›contrast‹. Secondly, the paper investigates the development and function of black-and-white images as tools of perception in the sciences. It finally discusses the specific knowledge generated through Malevich’s art and through scientific black-and-white images, following Max Scheler’s phenomenological identification of knowledge.

Cinema consists of two different dimensions of art and instrument. A tool that mixes with art and represents society in which anything can be depicted for others. But art has always sought to portray the beauties of this universe. The beauty that lies within philosophy. Since the advent of human beings, men have always sought to dominate and abuse women for their own benefit. In the 19th century, cinema entered the realm of existence and found its place in the human world. With the empowerment of cinema in the world, filmmakers tried to achieve their goals by using this tool.Many filmmakers use women as a propaganda tool to attract a male audience. In many films, when the hero of a movie succeeds in reaching a woman, or in doing so, she is succeeded by a woman. In this way, of course, women themselves are not faultless and have helped men abuse women. Afghanistan, a traditional and male-dominated country, has not been the exception, and in many Afghan films women have been instrumental zed and used in various ways to benefit men, and we have seen fewer films in which women be a movie hero or a woman in a movie like a man. This kind of treatment of women in Afghan films has caused other young Afghan girls to not have a positive view of Afghan cinema.

The dead have largely lost their social importance, visibility, and impact in American society. This event is essentially a phenomenon of the present century. For three centuries prior, the dead world occupied a significant and readily recognizable place in the living world. Indeed, that place was growing rapidly through much of the 19th century. Causes of the reversal in relationship between the two worlds are examined and consequences of the present radical withdrawal from the dead are suggested.

European Industrial Revolution in the eighteenth century brought great changes not only in Europe itself but also in other parts of the world including Indonesia which was used to be a country of Dutch colony. The invention of steam-powered ships triggered the Dutch to use steam-powered vessels as the alteration of yachts, wind-powered ships, in the 19th century. At the beginning, the steam-powered ships used rotating wheels in the left and right side; however, the ships finally used ordinary windmills or propellers. The decrease and the lack of this production was getting worsened the competition of other producer countries in world market and the unstable coal market and in crisis year in 1930, Pulau Laut Mining Company production dropped so that it was closed down in the same year.

Abstract John Wesley (1703-91)is known as the founder of Methodism in his time of Oxford University’s Scholar. However, about his Methodical religious theory, he got more spiritual and important influence from other continents not only Oxford in Great Britain but also Europe and America. Through Wesley’s experience and awakening in those continents, Methodism became the new religion with Revival by the spiritual power of “Holy Grail”. By this research using Multidisciplinary approach about the study of Legend of Holy Grail’s Knight, - from King Arthur and Knights of the Round Table in the Medieval Period, and in 18th century Wesley, who went to America in the way on ship where he met the Moravian Church group also called Herrnhut having root of Pietisms, got important impression in his life. After this awakening, he went to meet Herrnhut supervisor Zinzendorf (1700-60) in Germany who had root of a noble house in the Holy Roman Empire, - and to Legend of Holy Grail’s Knight Opera “Parsifal” by Richard Wagner at Bayreuth near Herrnhut’s land in the 19th century, Wesley’s Methodism is able to reach new states with the legend, such as the historical meaning of Christianity not only Protestantism but also Catholicism. I wish to point out Wesley’s Methodism has very close to Legend of Holy Grail’s Knight. In addition, after the circulation in America, in the late 19th century Methodism spread toward Africa, and Asian Continents. Especially in Japan, by Methodist Episcopal Church South, Methodism landed in the Kansai-area such international port city Kobe. Methodist missionary Walter Russel Lambuth (1854-1921) who entered into Japan founded English schools to do his missionary works. Afterward, one of them became Kwansei-Gakuin University in Kobe. Moreover, Lambuth such as Parsifal with Wesley’s theories went around the world to spread Methodism with the Spirit’s the Legend of Holy Grail’s Knight as World Citizen.

The article examines the concept of an epic novel – a special historical genre phenomenon that arose as a result of the successful implementation by Russian classics of the second half of the 19th century. The author discusses the pseudo-names that appeared in Soviet literary criticism due to its politicisation and ideologisation back in the 1920s –30s and she shows that the terms of epic novel and epopee novel were used at the indicated time for the sake of the Communist party tasks, but contrary to their true meanings. As noted in the article, this required a rejection of the traditions of Russian classical literature, a rejection of the genetic memory of the universal vision of the world and human inherent in the epic novel. Analytical comprehension of the polemics of literary critics of different generations made it possible to show that a number of researchers who rightly saw the problem, forgot to “rehabilitate” the above concepts and transferred the line of denial of Soviet ideology to the terms themselves. The author of the article explains the importance of using the concept of an epic novel in its true meaning, in relation to the voluminous works of Russian classical literature.
