AbstractBy the time you read this column, 2019 will have ended, and with it the important celebrations of IUPAC’s centenary and the International Year of the Periodic Table of the Chemical Elements (IYPT). Both of these have focused on the dissemination of knowledge, creating educational opportunities and information exchange as central ideas for IUPAC, as well as on the history of IUPAC since 1919 and the development of the periodic table. However, an ending is also a beginning; a forward-looking perspective behind the worldwide New Year 2020 celebrations at the end of one year and the beginning of the next. Remember the achievements in order not to forget, to move forward and build on them.

AbstractThis year (2009) marks the 140th Anniversary of Mendeleev's original 1869 periodic table of the elements based on atomic weights. It also marks the 175th anniversary of his birth in Tolbosk, Siberia. The history of the development of periodic tables of the chemical elements is briefly reviewed beginning with the presentation by Dmitri Mendeleev and his associate Nikolai Menshutkin of their original 1869 table based on atomic weights. The value, as well as the sometimes negative effects, of periodic tables in guiding the discovery of new elements based on their predicted chemical properties is assessed. It is noteworthy that the element with Z=101 (mendelevium) was identified in 1955 using chemical techniques. The discoverers proposed the name mendelevium to honor the predictive power of the Mendeleev Periodic Table. Mendelevium still remains the heaviest element to have been identified first by chemical rather than nuclear or physical techniques. The question concerning whether there will be a future role for the current form of the periodic table in predicting chemical properties and aid in the identification of elements beyond those currently known is considered.

The paper observes the matter of proper names of chemical elements of the periodic table by D.I. Mendeleev, the history of their origin, and transformation while the morphemic and semantic loaning from Greek and Latin languages. Moreover, the name for this lexis is proposed as stoichonyms. The topic under discussion is actual for chemistry students in classes of English. The paper provides an example of multilingual group of the speakers of Russian, Tajik, and Kyrgyz languages. The special interest is the comparative lexemic analysis of the names of chemical elements in these three languages. By means of it, one can conclude on the students' perception of the scientific lexis in the light of its etymology, on the one hand. On the other hand, one can make an approach to teaching the special lexis not only by language teacher but chemistry as well.

ABSTRACT: The history of Mendeleev's famous discovery has long been a matter of lively debate among experts. This essay proposes a new reading of this story, which differs from the well-known reconstructions made by Kedrov, Bensaude-Vincent, Graham and others. Particular attention is paid to the context of a Mendelevian thought and the analysis of the surviving outlines of his first variants of the Periodic Table. By considering Mendeleev's discovery of the Periodic Law one can identify the three principal stages in his work: 1) the composition of the ““first attempt””(pervaia proba) of the system of chemical elements and the discovery of the periodic character in dependence of the elements, properties on their atomic weights (late 1868-early 1869); 2) the composition of Attempt at a system of elements based on their atomic weights and chemical similarity as a temporary version of the Periodic Table (February 1869); 3) the composition of the Natural system of elements (November 1870). Mendeleevian work on Attempt revealed a lack of clear chemical criteria for unifying elements of different classes——the ““natural families”” and ““transitional metals””——into a general taxomonical scheme that forced him to reject the ideal structure of the system of elements that he had formed earlier (1868). It was only by November of 1870 that Mendeleev finally solved the ““unification problem,”” formulating the basic principles of his system. This article also discusses how Mendeleev's views on the structure of the Periodic System were mediated by his convictions regarding the constitution of organic compounds.

This work is aimed at young people at the age of 14 to 15 years old.The work is based on the study of the Periodic Table. Students show a great interest in learning about the history of the periodic table, as well as the details of each chemical element individually. They want to know how it was discovered, the scientist who did it, in which rock we can find it, where we use it, its properties, and much more.Combining the two sciences, Geology and Chemistry, we make a blank Periodic Table with dimensions of 2m to 1,5m. We also make cards with the elements.The aims are:<ul><li>- To help students study the periodic table through various table games and learn not only the names of chemical elements but their inseparable relationship with the Earth and man.</li> <li>- To make it clear that everything we need and use has its origins in the Earth.</li> <li>- To emphasize the origins of the chemical elements in the minerals and the rocks.</li> </ul>For every element there are several cards. An example is Al (Aluminum). For Al, there is a card with the chemical symbol of Al, a card with the picture of Bauxite (the rock from which we get aluminum), a card with the materials made of Al, a card with a small quiz about some of its chemical or physical properties, etc. &#932;he cards have colors depending on the group that the chemical elements belong to. There are also cards with the history behind a chemical element.Students are divided into groups, in which they then pick up different cards and try to place the chemical elements in the correct box in the periodic table.Another game they like to play is to pick a card with the element&#8217;s symbol on and try to guess the name of the element and to associate it with the suitable mineral or rock card.In addition, the students are given atoms and bonds simulations, as well as the chemical type of a mineral and a picture or a real part of a rock, in which we find the mineral. Their goal is to construct the mineral using the simulations and the written directions. &#921;n this way, they also recognize the rocks in which the chemical elements are found.The most interesting in the above process is that students prepare the cards themselves. Thus, they are also actively involved in the process of creating their own periodic table.In 2019, the scientific world celebrated the 150th anniversary since the creation of the periodic table. Our students, after playing such games as the above, decided to celebrate the International Year of P.T. by painting their own periodic table on canvas.Their work is now hanging in a central school area.

Abstract The history of chemistry has not once seen representations of the periodic system that have not received proper attention or recognition. The present paper is dedicated to a nearly unknown version of the periodic table published on the occasion of the centenary celebration of Mendeleev’s birth (1934) by V. Romanoff. His periodic table visually merges Werner’s and Janet’s periodic tables and it is essentially the spiral periodic system on a plane. In his 1934 paper, Romanoff was the first one to introduce the idea of the actinide series, a decade before Glenn T. Seaborg, the renowned creator of the actinide concept. As a consequence, another most outstanding thing about Romanoff’s paper occurs towards its very end: he essentially predicted the discovery of elements #106, #111 and #118. He theorized that, had uranium not been the “creative limit”, we would have met element #106, a “legal” member of group 6, element #111, a precious metal, “super-gold” and element #118, a noble gas. In 2019, we take it for granted that elements #106, #111 and #118 indeed exist and they are best known as seaborgium, roentgenium and oganesson. It is fair to say that Romanoff’s success with the prediction of correct placement and chemical properties of seaborgium, roentgenium and oganesson was only made possible due to the introduction of an early version of the actinide series that only had four elements at that time. Sadly, while Professor Romanoff was imprisoned (1938–1943), two new elements, neptunium (element #93) and plutonium (element #94) were discovered. While Professor Romanoff was in exile in Ufa (1943–1953), six further elements were added to the periodic table: americium (element #95), curium (element #96), berkelium (element #97), californium (element #98), einsteinium (element #99) and fermium (element #100). The next year after his death, in 1955, mendelevium (element #101), was discovered. Romanoff’s version of the periodic table is an unparalleled precursor to the contemporary periodic table, and is an example of extraordinary anticipation of the discovery of new chemical elements.

Abstract Last time I wrote to you, we were finishing 2019, IUPAC’s centenary celebrations and the International Year of the Periodic Table of the Chemical Elements (IYPT). Since then, our world and how we related to it has changed dramatically. One year ago, we could not have imagined today’s reality. We are dealing with the consequences of a virus we knew little about and for which vaccines are starting to become available only now. The fact that the time for the development of vaccines has been shortened from several years to less than one year, is in itself the result of a huge scientific achievement; it involves interdisciplinary collaborations from microbiology to medicine, but also crucially underpinning chemistry. The pandemic has meant that our daily habits have changed, that we cannot travel or only with heavy restrictions, and that now we mostly meet on-line.

Background: Although foam sclerotherapy of varicose tributaries is common in daily practice, scientific evidence for the optimal sclerosant-concentration and session-frequency is still low. This study aimed to increase the knowledge on foam sclerotherapy of varicose tributaries and to evaluate the efficacy and safety of foam sclerotherapy with 0.5 % polidocanol in tributaries with 3-6 mm in diameter. Patients and methods: Analysis of 110 legs in 76 patients. Injections were given every second or third day. A maximum of 1 injection / leg and a volume of 2ml / injection were administered per session. Controls were performed approximately 6 months and 12 months after the start of therapy. Results: 110 legs (CEAP C2-C4) were followed up for a period of 14.2 ± 4.2 months. Reflux was eliminated after 3.4 ± 2.7 injections per leg. Insufficient tributaries were detected in 23.2 % after 6.2 ± 0.9 months and in 48.2 % after 14.2 ± 4.2 months, respectively. Only 30.9 % (34 / 110) of the legs required additional therapy. In 6.4 % vein surgery was performed, in 24.5 % similar sclerotherapy was repeated. Significantly fewer sclerotherapy-sessions were required compared to the initial treatment (mean: 2.3 ± 1.4, p = 0.0054). During the whole study period thrombophlebitis (8.2 %), hyperpigmentation (14.5 %), induration in the treated region (9.1 %), pain in the treated leg (7.3 %) and migraine (0.9 %) occurred. One patient with a history of thrombosis developed thrombosis of a muscle vein (0.9 %). After one year there were just hyperpigmentation (8.2 %) and induration (1.8 %) left. No severe adverse effect occurred. Conclusions: Foam sclerotherapy with injections of 0.5 % polidocanol every 2nd or 3rd day, is a safe procedure for varicose tributaries. The evaluation of efficacy is difficult, as it can hardly be said whether the detected tributaries in the controls are recurrent veins or have recently developed in the follow-up period. The low number of retreated legs indicates a high efficacy and satisfaction of the patients.

Radical Ideas

Isaac Newton’s Chronology of Ancient Kingdoms Amended, published in 1728, one year after the great man’s death, unleashed a storm of controversy. And for good reason. The book presents a drastically revised timeline for ancient civilizations, contracting Greek history by five hundred years and Egypt’s by a millennium. This book tells the story of how one of the most celebrated figures in the history of mathematics, optics, and mechanics came to apply his unique ways of thinking to problems of history, theology, and mythology, and of how his radical ideas produced an uproar that reverberated in Europe’s learned circles throughout the eighteenth century and beyond. The book reveals the manner in which Newton strove for nearly half a century to rectify universal history by reading ancient texts through the lens of astronomy, and to create a tight theoretical system for interpreting the evolution of civilization on the basis of population dynamics. It was during Newton’s earliest years at Cambridge that he developed the core of his singular method for generating and working with trustworthy knowledge, which he applied to his study of the past with the same rigor he brought to his work in physics and mathematics. Drawing extensively on Newton’s unpublished papers and a host of other primary sources, the book reconciles Isaac Newton the rational scientist with Newton the natural philosopher, alchemist, theologian, and chronologist of ancient history.
