Prior to the eighteeth-century, a similar approach towards the vegetable kingdom, mainly influenced by the tradition of the Chinese pharmacopoeias, could be observed in China and Japan. During the eighteenth-century, the interest for <<Dutch learning>> led some Japanese physicians and interpreters to be more and more interested in Western knowledge about medicinal plants. At the beginning of the nineteenth-century, a few scholars, through direct contact with foreigners or with foreign books, realised that there was a specific scientific field called <<botany>> and began to introduce the Japanese sholarly community to this new science which became one of the subjects taught at the <<University of Tokyo>> in 1877. In China, up to the middle of the nineteenth-century, no trace of modern botany can be found in any published document. In the second half ot the century, a few botanical treatises were published, all being adaptations or translations of Western books, does by foreign-Chinese teams of translators. This situation began to change when Chinese students had the opportunity to go and study abroad, mainly to Japan, at the beginning of the twentieth-century, and, actually, it is between 20 and 30 years later that botany became a real scientific practise in China. We will analyse these two processes, their specificities and their interactions.

This paper traces the roots of the image of the atomic bomb in Japan by investigating the various discourses on atomic energy and atomic weapons in Japanese literature prior to the bombing of Hiroshima in August 1945. Japan is a country that suffered an atomic attack and, at the same time, one of the countries that was engaged in atomic weapons research during the Second World War. During the war, the discourses on atomic weapons were not limited to the military or scientific communities, but included the general public, thus facilitating the creation of a shared image of the atomic bomb as an ultimate weapon. This paper examines how this image was created. This special issue deals with the comparison among different countries, but the purpose of my paper is to deepen this subject by illustrating the differences within a single country in different periods. This research aims to extend the historical perspective concerning the atomic bomb in Japan, and offers another way of looking at this both historical and contemporary issue.

Two atomic bombs dropped on Hiroshima and Nagasaki in August 1945 brought the unexpected liberation of Korea from the 35-year Japanese occupation. Koreans therefore had a very favorable and positive image of the nuclear bomb and nuclear energy from the beginning. The image of the nuclear bomb as "savior" was strengthened during the Korean War when the United States openly mentioned the possible use of the nuclear bomb against North Korean and Chinese military. After the end of the Korean War in July 1953 South Koreans strongly supported the development of the nuclear bomb in order to deter another North Korean invasion. When the US government provided South Korea with a research nuclear reactor in the late 1950s, most South Koreans hailed it as the first step to developing their own nuclear bomb. This paper will analyze how and why the savior image of the nuclear bomb originated and spread in Korea during the 1950s.

This paper explores how Edmund C. Berkeley tried to instruct and popularize high-speed computers in the 1940s and 1950s and how Berkeley emphasized the connection between computers and symbolic logic. Berkeley strengthened his conviction in the significance of symbolic logic and Boolean algebra before his graduation from Harvard University and maintained this conviction for more than 30 years. Berkeley published books and articles, including Giant Brains, and sold electrical toy kits by which yound boys could learn electrical circuits and their logical implications. The target audience of Berkeley covered wide range of people including those who were not making computers but were interested in using them, that is, amateur adults technology enthusiasts who enjoyed tinkering with technology or reading about science and technology, and young students. In these projects Berkeley used Shannon's paper of 1938, "A symbolic analysis of relay and switching circuits" as a theoretical basis of his conviction. Design of these kits was fine-tuned by Claude E. Shannon.

In Japan, evolutionism became popular towards the end of nineteenth century. Mendelism became popular around 1920. Mendelian genetics has become one of the important branches of Japanese biology. But evolutionism did not become an academic subject among Japanese biological researchers. Popularization of Mendelism had not changed this state of evoutionism in Japan. In this report I will describe mainly the state of evolutionism in Japan untill the 1920s, and comment briefly on the state of evolutionism arter that.

I am dwelling on Bessel's indirect conflict with Gauss over the adjustment of triangulation, a subject overlooked by Biermann and other commentators, e.g., May. I begin by touching on Biermann's paper who discussed the relations between the two scholars and provide my own relevant material in §§3 and 4. I also have to explain the two main patterns of adjusting geodetic measurements (§2), and to formulate some conclusions and offer additional related considerations (§5). Finally, §6 is devoted to several new unexpected dramatis personae.

Max Planck(1858-1947) introduced energy quanta into his radiation theory in December 1900. Energy quanta, together with Albert Einstein's theory of relativity, heralded the beginning of today's physics. Although Planck differed from Einstein in being a completely classical physicist, he successfully introduced this non-classical conception into his theory. Why was it that Planck had worked out it in his heat radiation theory? In order to approach this question, we will focus on the formulation of the "electromagnetic entropy" of a resonator in the theory and argue Planck's method of radiation theory had both inductive and deductive aspects. His method was inductive because he always defined the formula of entropy so that the experimentally confirmed spectral distribution law of radiation energy could be derived from it, and also deductive because he derived some important mathematical formulas from classical electromagnetic and thermodynamic theories. The method was different from those of other researchers on heat radiation at the time, those of not only theoretical but also experimental physicists. Planck did take the original theoretical induction of the entropy concept from experimental results and derive his radiation law. The present article first outlines the paper Planck presented on May 18, 1899, focusing on how he treated the entropy formula. It then reconsiders the origin of the formula for entropy as postulated in previous studies, concluding with a discussion of Planck's radiation research method and its historical significance.
