To mark the 25th anniversary of the collapse of the communist regime in the former Czechoslovakia and other countries in Central and Eastern Europe, the editorial board of PaD decided to ask historians who deal with this topic to answer the question of which factors, in their opinion, had most contributed to the fall of the communist regimes in Central Europe. Here are some of their answers.

Před více než dvěma lety přišlo občanské sdružení Ná- rod pohasl s nápadem proměnit všetatský domek rodiny Jana Palacha v jeho památník. V prosinci 2013 uvolnila Poslanecká sněmovna na tento projekt finanční prostředky. V poradní komisi ministra kultury, v níž jsou zástupci ministerstva kultury, Národního muzea, občanských sdružení, historici i starosta obce Všetaty, se v současnosti debatuje o jeho podobě. V této souvislosti oslovila redakční rada revue Paměť a dějiny několik osobností s prosbou o dopověď na otázku: Jakou podobu a obsah by měl mít a jakou roli by podle vás měl hrát památník Jana Palacha?

Polish Statistical Association (PTS) was established in Kraków in 1912. The history of the PTS in Wielkopolska region began in 1915. The study shows the stages of development with particular emphasis on those persons who have formed the organization and its leaders. The four periods were extracted: the interwar period (1915―1939), World War II (1939―1945), post-war period (1945―1981) and the period after PTS reactivation in 1981.

In the consecutive years 1965, 1966, 1967, George Şt. Andonie published a trilogy entitled Istoria matematicii în România (The history of Mathematics in Romania). In these volumes we find extensive biobliographical information about the personalities in the mathematics education and research in our country, from many centuries ago until the days when the books were written.

Collecting the impressive patrimony of the “Grigore Antipa” National Museum of Natural History from Bucharest, during the 180 years of existence, has required an immense creative energy, and the extensive work of the scientists who have contributed to this cultural institution. Some of these collections have been formed and enriched through the selfless devotion and the love for the nation of some famous people in different fields, who donated various samples. Our work pays homage to these people, who through their small contribution helped the museum exist and grow. Therefore, we believe that their names and their donations, which have been maintained in the archives of the collections, must be made known to the future generations.

This paper aims to further develop issues related to magnitude, as a measure of earthquake strength, focusing on the relationship between magnitude and seismic energy. It also presents a brief history of the scientific activity of personalities who analysed seismic energy vs. magnitude and provided certain numerical calculations of them. They also established well-known magnitude scales: Richter and the seismic moment.

The identification and evaluation of environmental pollution is a study based on methods designed and developed by Conrad Schlumberger and Sabba S. Ștefănescu, two geniuses of Geophysics. The former is the founder of the resistivity method, which determines the processes underlying electrical measurements, and the latter is the one who develops the method and takes it to the level of geoelectrical tomography. This helps specialists in research and exploration to monitor the anthropogenic activities which occur at ground level and even to anticipate the anthropic evolution. The processing of signals of a diagram, in particular – the electrical resistivity, describes the variations of randomly recorded data that determine the depth of a layer.

The paper refers to excerpts from the Historiography of Mathematics dedicated to mathematicians Petre Sergescu and Solomon Marcus and especially engineer George Şt. Andonie. Petre Sergescu was an important historiographer of Mathematical sciences from his time in the entire world. He published articles written in Romanian and French about Gheorghe Țițeica, Traian Lalescu, David Emmanuel, Dimitrie Pompeiu, and others. Sergescu also reflected a lot on education by Mathematics. Solomon Marcus wrote many pages and books about mathematicians and Mathematics in Romania. George Şt. Andonie is the most important historiographer of Mathematics in Romania. In his volumes ''Mathematics in Romania”, he also refers to Sergescu and Marcus.

The remarkable scientific concerns of the renowned Academician Emil Pop, a leading exponent of the „Babeș Bolyai” University of Cluj, included par excellence the fields of palinology, Pliocene flora of Eastern Carpathians, the peat bogs in Romania, the knowledge of nature reserves and the large scale nature protection cam paign whose assiduous promoter he remained throughout his whole professional career. He presented the development of the laboratory of plant anatomy and physiology of the Faculty of Natural Sciences of the university. He also emphasized the role of Emil Racoviță in the progress of botany, specifying the plant and animal species that were dedicated to him. Another relevant example, chosen from his teaching activity, aimed at getting to know and explain the phenomena of aging and death in the plant and animal world. Another significant episode is the correspond ence relationship with the most important marine algologist in Romania, Maria S. Celan. Particularly erudite and emotional is the speech on the occasion of the meeting of the 1915 class of „Andrei Șaguna” High School in Brașov. He died unexpectedly in 1974.

The evolution of Romanian science and technology, most often under the influence of movements in the political world, has recorded over the last two centuries, periods of stagnation and unex pected leaps, the latter being generated by the emergence of some reforms or development initiatives, which were generated at the level of political leadership. This is how things happened during the reign of Alexandru Ioan Cuza and Carol I of Romania, also Ferdinand I of Romania (to a lesser extent) and especially during the Ceaușescu Regime. Especially after the events (Soviet intervention in Czechoslovakia) that took place in the summer of 1968, in Romania, the political decision gave the start of a vast program of development and modernization. That initiative has cov ered a lot of economic and technical scientific aspects, referring to a large number of scientific and economic areas. The research and development activity, in particular, was very advantaged. The activity of the Romanian researcher and inventor Nicolae Moraru was largely part of this histori cal context. He was a researcher at ICENERG ( later, ICEMENERG) Bucharest, carried out a research activity that first aimed at understand ing the phenomena of generation and natural transport of electrons in the Earth’s atmosphere, also, the applications of these phenomena in the field of electromagnetic weapons; the designing and developing for new models of electric motors and electrochemical sources intended for them; the remotorisation of the Dacia 1300 chassis with an electric motor of exclusively Romanian design and production; the improvement of combustion processes in industrial boilers and in the scheme of internal combustion engines etc. This paper comes as a restitution for the history of Romanian science and technology, seeking to bring back to the atten tion of the academic environment and of the general public, datas and informations about personalities and facts unjustly forgotten or erased from the official history.

Born on 9 August 1938 in Bucharest, Oscar Edelstein is a lead ing Romanian geologist. He has made major contributions to the field of economic geology (for which he received the “Gheorghe Murgoci” Award of the Romanian Academy in 1977), as well as to stratigraphy paleontol ogy, cartography, mineralogy petrography. He is a distinguished member of several professional associations: the Geological Society of Romania (President of the Baia Mare Branch 1990–2003); the Romanian Society of Economic Geology, the National Association of Professionals in Geology and Mining, the Association of Amateur Mineralogists, Paleontologists and Gemologists from Romania. He has authored over 70 specialized articles and has coordinated the publication of the monumental volume entitled “Dictionary of geologists who worked in the Baia Mare area and adjacent areas” (Dicționarul geologilor care au lucrat în zona Baia Mare și în ariile adiacente) (2008, 2014).
