How G. B. Halsted contributed to the international recognition of János Bolyai and Nikolai Lobachevsky
type: item
description: George Bruce Halsted was born on November 23, 1853, in Newark, New Jersey, USA as son of Adela Meeker and Oliver Spencer Halsted. His father was a lawyer. Halsted studied at Princeton University, as did his father, grandfather and great-grandfather. He completed his bachelor's degree in 1875 and his master's degree in 1878. He received his doctorate in 1879 from Johns Hopkins University with his thesis Basis for a Dual Logic. In the meantime, he also studied in Berlin. He remained an intern at Princeton for a time and then taught mathematics at the University of Texas from 1884 to 1903. It was during this time that his professional work was completed. Despite his eccentric behavior, he was a popular teacher among his students. He studied, explained and translated into English the works of Lobachevsky, János Bolyai, Saccheri and Poincaré. After a clash with the university management over a teacher competition when hiring a candidate with better connections rather than the more talented one, he had to leave the university. He then taught in several places: St. John's College, Annapolis, Maryland (1903); Kenyon College, Gambier, Ohio (1903–1906) and Colorado State Teachers' College, Greeley (1906–1912). He then retired, continuing to study mathematics while working as an electrician in the family business. He died March 16, 1922, in New York. He was mourned by his wife, Margaret Swearingen (whom he married in 1886) and his three sons. The fact that this genius mathematician and noble-minded man ended his life as an electrician reminds us of the words of the Hungarian poet, János Batsányi, which can be found on the memorial plaque of his former residential building in Linz: “The present can be envious and ungrateful, but the future will be fair. ” Kivonat George Bruce Halsted 1853. november 23-án született a Newarkban, New Jersey államban, az Egyesült Államokban. 1879-ben doktorált a Johns Hopkins Egyetemen, disszertációjával "A duális logika alapjai". Időközben Berlinb…

Pe urmele relicvelor Bolyai pierdute – Vioara lui János Bolyai
type: item
description: This work was developed starting from the lectures given by the author in November 2023 in Timișoara during the Bolyai 200 Art and Science Festival held on the occasion of the 200th anniversary of János Bolyai's letter written from Temesvár (Timișoara), as well as at the Bolyai Commemorative Festive Meeting at the Bolyai Institute of the University of Szeged. The research started on the trail of János Bolyai's violin, which the literature assumed it was lost 120 years ago. But based on the newly discovered data, a vague hope was born that this precious relic of Bolyai might be rediscovered one day. Hopefully, the Romanian translation can also help with this. Rezumat Această lucrare a fost elaborată pornind de la două prelegeri ale autorului. Prima dintre ele a avut loc în noiembrie 2023 la Timișoara în cadrul Festivalului de Artă și Știință Bolyai 200 organizat cu ocazia aniversării a 200 de ani de la scrisoarea lui János Bolyai trimisă de la Timișoara tatălui său. Cea de-a doua prelegere a fost prezentată la Szeged (Ungaria) în cadrul Ședinței Festive de Comemorare Bolyai de la Institutul Bolyai al Universității din Szeged. Cercetarea a pornit pe urmele viorii lui János Bolyai, despre care literatura de specialitate presupunea că a fost pierdută cu 120 de ani în urmă. Însă pe baza datelor nou descoperite s-a născut o speranță vagă că această prețioasă relicvă a lui Bolyai ar putea fi redescoperită într-o bună zi. Sperăm că traducerea articolului în limba română poate ajuta în acest sens. Kivonat Ez a dolgozat Bolyai János Temesvárról édesapjához írott levelének 200. évfordulója alkalmából a szerzőnek 2023 novemberében Temesvárott a Bolyai 200 Művészeti és tudományos fesztiválon, valamint Szegeden az SZTE TTIK Bolyai Intézetének Bolyai Emlékülésén tartott előadásainak lejegyzése alapján készült. A kutatás Bolyai János hegedűjének eredt a nyomába, amelyről a szakirodalom eddig úgy tudta, hogy 120 éve elveszett. A fellelt újabb adatok alapján azonban halvány remény ad…

A kolozsvári székhelyű Első Erdélyi Papírlemezgyár alapítói és működtetői
type: item
description: One of the important areas of Cluj's industrial history is paper production, the beginnings of which go back to the middle of the 16th century. Although the first paper mill in (Kolozsvár) Cluj-Napoca started operating in 1564 thanks to Gáspár Heltai, we can only speak of paper production on an industrial scale at the end of the 19th century. The junior The First Transylvania Paper Mill (Első Erdélyi Papírlemezgyár), founded by Dániel Warga and Sándor Babos, supplied not only the city, but also other parts of Transylvania with high-quality paper products for half a century. Rezumat Una dintre zonele importante ale istoriei industriale a Clujului este producția de hârtie, ale cărei începuturi datează de la mijlocul secolului al XVI-lea. Deși prima fabrică de hârtie din Kolozsvár (Cluj-Napoca) a început să funcționeze în 1564 datorită lui Gáspár Heltai, nu putem vorbi de producția de hârtie la scară industrială decât la sfârșitul secolului al XIX-lea. Prima fabrică de hârtie din Transilvania (Első Erdélyi Papírlemezgyár), fondată de Dániel Warga și Sándor Babos, a furnizat nu numai orașului, ci și altor părți ale Transilvaniei produse de hârtie de înaltă calitate timp de o jumătate de secol. Kivonat Kolozsvár ipartörténetének egyik fontos területe a papírgyártás, melynek kezdetei a XVI. század közepéig nyúlnak vissza. Bár az első kolozsvári papírmalom Heltai Gáspárnak köszönhetően már 1564-ban megkezdte működését, ipari méretű papírgyártásról csak a XIX. század végéről beszélhetünk. Az ifj. Warga Dániel és Babos Sándor által megalapított Első Erdélyi Papírlemezgyár fél évszázadon keresztül látta el jó minőségű papírtermékekkel nemcsak a várost, hanem Erdély más részeit is.

Hevesy György, a kémia óriása
type: item
description: József György Hevesy was both a physicist and a chemist. He graduated in chemistry in Germany. In 1911, he worked in Rutherford's laboratory in Manchester, where he met and made a lifelong friendship with Niels Bohr. In 1913, he discovered the radioactive tracer method. In 1920, he went to Copenhagen and continued his research at Bohr's institute. In 1923 he discovered and analyzed the new element 72, which he named hafnium, the Latin name for Copenhagen. Later on, he often visited Denmark, from where he fled from Nazi persecution to Sweden during the war. At that time, the radioactive tracer method he discovered was widely used throughout Europe, which was recognized by the scientific world by awarding him the 1943 Nobel Prize in Chemistry. He took up Swedish citizenship, but kept his Hungarian passport until the end of his life. Shortly before his death, he visited home once more and received his honorary doctorate from ELTE and the Budapest University of Technology.The Carpathian Basin Chemistry Competition, held every year, bears his name. Rezumat József György Hevesy a fost atât fizician, cât și chimist. A absolvit chimia în Germania. În 1911, a lucrat în laboratorul lui Rutherford din Manchester, unde l-a cunoscut pe Niels Bohr și a legat o prietenie de-a lungul vieții cu el. În 1913, a descoperit metoda trasorului radioactiv. În 1920, a plecat la Copenhaga unde și-a continuat cercetările la institutul lui Bohr. În 1923 a descoperit și analizat noul element 72, pe care l-a numit hafniu, denumirea latină pentru Copenhaga. Mai târziu, a vizitat adesea Danemarca, de unde a fugit de persecuția nazistă în Suedia în timpul războiului. La acea vreme, metoda trasorului radioactiv pe care a descoperit-o era folosită pe scară largă în toată Europa, care a fost recunoscută de lumea științifică prin acordarea Premiului Nobel pentru Chimie în 1943. A obținut cetățenia suedeză, dar și-a păstrat pașaportul maghiar până la sfârșitul vieții. Cu puțin timp înainte de moartea sa…

A Bolyai-kultusz az erdélyi magyar sajtóban 1945 előtt
type: item
description: The compilation is a selection of articles about Bolyais published in the Transylvanian Hungarian press before 1945. Based on this, it can be stated that, contrary to public opinion, quite a few articles were published about the Bolyai people, especially after the 1903 commemorations, and not only in the newspapers published in Kolozsvár and Marosvásárhely. Kivonat Az összeállítás az erdélyi magyar sajtóban 1945 előtt megjelent Bolyaiakról szóló írásokból válogat. Ennek alapján ki lehet jelenteni, hogy a közvélekedéssel ellentétben, nem kevés írás jelent meg a Bolyaiakkal kapcsolatban, főleg az 1903-as megemlékezések után, és nem csak kolozsvári és marosvásárhelyi lapokban.

Pörgettyűs teodolitok fejlesztése a Magyar Optikai Műveknél
type: item
description: The series production of various types of geodetic instruments using the gyroscopic principle, developed, and manufactured in Hungary, was carried out at the Hungarian Optical Works from the 1960s for almost three decades, but this activity can now be considered a closed chapter. Its history is an important chapter in the history of Hungarian industry. This process of enterprise-driven and highly successful innovation is particularly relevant today. Kivonat A magyar fejlesztésű és gyártású, giroszkópikus elvet alkalmazó geodéziai műszerek különböző típusainak sorozatgyártása a Magyar Optikai Műveknél a múlt század hatvanas éveitől közel három évtizeden át folyt, de ez a tevékenység mára sajnos lezárt fejezetnek tekinthető, története azonban a magyarországi ipartörténet fontos fejezete. Ez a vállalati indíttatású és rendkívül sikeres innovációs – és napjainkban is sok tanulsággal szolgáló – folyamat mai szemmel különösen aktuális.

Pathi Nagy Sámuel (1770–1810) szellemi világa – könyvtárának jegyzéke alapján
type: item
description: Sámuel PATHI NAGY studied in the Protestant College in Debrecen, later in Jena. Here he became the Hungarian secretary of the Mineralogical Society. Returning home, he worked as medical doctor in Komárom. After his death the catalogue of his private library was published which gives a good insight into the sources of his knowledge and cultural background. In this abstract mostly his books dealing with natural history, theology of nature and education are discussed. Rezumat Sámuel PATHI NAGY a studiat la Colegiul Protestant din Debrecen, ulterior la Jena. Aici a devenit secretarul maghiar al Societății Mineralogice. Întorcându-se acasă, a lucrat ca medic la Komárom. După moartea sa, a fost publicat catalogul bibliotecii sale private, care oferă o bună perspectivă asupra surselor sale de cunoștințe și de cultură. În acest rezumat sunt discutate cărțile sale despre științele naturale, teologia naturii și educația. Kivonat PATHI NAGY Sámuel a debreceni Református Kollégiumban, majd Jénában végezte tanulmányait. Jénában az Ásványtani Társaság magyar titkára lett. Hazatérve Komáromban működött mint orvos. Halála után kiadták magánkönyvtára katalógusát. Ez jó betekintést ad tudása és műveltsége forrásaiba. Ebben a kivonatban főleg természettudományos, a természet teológiájával és neveléssel foglalkozó könyveit tárgyaljuk.

Szász József (1782–1812) kéziratos ásványtani táblázatai a Teleki Tékában
type: item
description: The mineralogical collection of the Teleki Téka Library in Marosvásárhely was founded by Domokos Teleki (1773-1798) and further developed by his father, Sámuel Teleki (1739-1822). The first two catalogues of the collection were written personally by Domokos Teleki. The last one was proved to be written in 1831 or later, its author is unknown. In addition to the catalogues there are many large hand-written tables which do not list the samples of the collection. In these tables the minerals are listed in systematic order and are characterised by their external properties. The number of the minerals listed is about 470 and the maximal number of the external properties 40. The sequence of the minerals follows the mineral systems generally accepted in the age. The external properties are almost identical with those proposed by Werner. Certainly, the tables were prepared in Jena. In addition, there is a booklet written in Hungarian on the chemical analysis of minerals. Unfortunately, no author and year can be found in the tables. However, considering the correspondence of Sámuel Teleki, and graphologic analysis of the manuscripts, their author was almost certainly the librarian József Szász (1782-1812). His duty was to care of the mineral collection. By support of Sámuel Teleki he studied 1808-1810 in Jena. In Jena he became member and later the Transylvanian secretary of the Mineralogical Society. Until now, his activity in mineralogy was almost unknown. He can be honoured as one of the first followers of Werner in Hungary. Rezumat Colecția mineralogică a Bibliotecii Teleki din Marosvásárhely/Târgu Mureș a fost fondată de Domokos TELEKI (1773–1798) și dezvoltată în continuare de tatăl său, Sámuel TELEKI (1739–1822). Primele două cataloage ale colecției au fost scrise personal de Domokos TELEKI. Ultimul a fost scris în 1831 sau mai târziu, autorul acestuia nu este cunoscut. În plus față de cataloage, există multe tabele mari scrise manual, care nu listează mostrele colecț…

Változó számjegyeink

description: We use numbers daily, not only mathematicians, but everybody. We have been using them so much that we have forgotten what a big discovery numerals have been for humanity. Some people consider that this was the biggest discovery of humanity for the last 2000 years. Roman numerals have spread throughout Europe because of the Roman empire, for almost one and half millennia. But it was very difficult to perform calculations with these early numerals, people used the abacus instead. When Hungarians came into Europe (896 A.D.), they had their own runic writing. But when St.Stephan I. converted Hungarians to Christianity (about 1000 A.D.), they began to use the Roman numerals. Today we use the indo-arabic numerals. These were introduced into Europe by Fibonacci (by 1200 A.D.), because it was much easier to do calculations with these ones, than with the roman numerals. It took about 2-300 years before Europe became convinced of the usefulness of indo-arabic numerals. From where, how and when did these numerals spread in Transylvania? This article aims to answer these questions, by examining old books and paintings, coins, old churches, church bells and baptismal fonts. Rezumat Astăzi folosim cifrele zilnic, nu numai matematicienii, ci cu toții. Le folosim atât de des, încât am și uitat ce mare descoperire au fost cifrele pentru omenire. Unii consideră că cifrele au fost cea mai mare invenție a omenirii din ultimele două milenii. Cifrele romane s-au răspândit în întreaga Europă datorită Imperiului Roman, pentru aproape un mileniu și jumătate. Dar era foarte greu să se facă calcule cu aceste cifre, se folosea de obicei abacul pentru efectuarea operațiilor matematice. Când maghiarii au venit în Europa (anul 896), au avut sistemul propriu de cifre runice. Dar când regele Stefan I. și-a convertit poporul la creștinism (aproximativ 1000 d. Hr.), au început să folosească și ei cifrele romane. Azi folosim cifrele indo-arabe. Acestea au fost introduse de Fibonacci (prin anul 1200), …

He received his civil engineering degree at Royal Joseph University in 1933. With the recommendation of his professor Károly Oltay he began working at Hungarian Optical Works as a designer of surveying instruments. The importance and the modernity of his instruments was demonstrated by the fact that he was awarded the Kossuth Prize for designing successful and well-known instruments abroad in 1958. The instrument family – the Te-D1 theodolite, the Ni-B1 optical level and the Ma-1 plane table –, designed alongside his leadership, received the Grand Prix award at the World Exposition 1958 in Brussels. He received a scientific degree from the Hungarian Academy of Sciences for his activities in the field of design and scientific work in 1959. He taught at the Institute for Advanced Engineering of Technical University of Budapest for several years, lecture notes written by him on measuring technology are still in use Today. One of his greatest professional achievements was the introduction of the production of glass circles in Hungary. He died in 1975 in Budapest. The article presents the life and technical works of Károly Bors mainly from the point of view of evolution Hungarian surveying instruments industry.

Emléktáblák a Szegedi Tudományegyetem, Ásványtani, Geokémiai és Kőzettani Tanszékén
type: item
description: The history of the Department of Mineralogy, Geochemistry and Petrology began in 1921, similarly to the present University of Szeged. In this year, the Hungarian Government, with the help of the exiled professors from the University of Kolozsvár, have established the Mineral and Geological Institute within Franz Joseph University, which was relocated to Szeged after the Trianon Peace Treaty, came in force in Transylvania. In this study, the life and working career of the former three Heads of Department professors can be followed, they are considered to be the school-founding individuals of Hungarian Earth Science. The first person presented is Prof. Zsigmond Szentpétery, who led the Institute between 1924-1940. Prof. Szentpétery created, founded and developed the Department almost from scratch, as most of the assets, library and equipment have been left in Cluj as per the Trianon Dictation. The second professor introduced is Sándor Koch, who acted as Head of Department between 1940-1968. He was the creator of the internationally renowned Sándor Koch mineral collection, which has been completed with his own mineral collection and specimens purchased on mineral collecting roads. Finally, the third famous professor presented is Gyula Grasselly, he led the Department be­tween 1968-1986. Prof. Grasselly who himself was an internationally renowned expert in manganese research, and during his leadership Geochemistry has been introduced as a new research field in the Department. As a sign of our respect, all three professors have been honoured with commemorative plaques at the Department of Mineralogy, Geochemistry and Petrology. The memorial plaques of Prof. Zsigmond Szentpétery and Prof. Gyula Grasselly were placed at the entrance of the Microscope Room and Lecture Room bearing their name, respectively. Prof. Sándor Koch's memorial plaque has been inaugurated on his 100th birth anniversary and can be found at the entrance of the Department. Rezumat Istoria Departamentulu…

Adalékok Wald Ábrahám életrajzához
type: item
description: One hundred years after the birth of János Bolyai, another well-known mathematician, Ábrahám Wald, was born in Cluj-Napoca. Ábrahám Wald was born into a Jewish-Orthodox family. Unfortunately, we don't have many documents about Wald's life. In modern statistics and econometrics many theorems of Wald's name are related. In this article we present original documents about the life of Ábrahám Wald, namely: the matriculation register from the Piarist High School in Cluj, and 3 letters of Ábrahám Wald written to György Alexits in Hungarian. Our presentation is an authentic first publication. At the end of this article, we emphasize the importance of commemorating the intellectual and material heritage of Ábrahám Wald. The commemoration of Wald's legacy should be manifested by the unveiling of a memorial plaque at Wald's parental home in Cluj-Napoca. Rezumat Cu o sută de ani după nașterea lui János Bolyai, la Cluj-Napoca s-a născut și un alt matematician renumit: Ábrahám Wald. Ábrahám Wald s-a născut într-o familie evreu-ortodoxă. Din păcate, nu avem multe documente despre viața lui Wald. În statistică modernă și în econometrie sunt legate multe teoreme de numele lui Wald. În acest articol vă prezentăm documente originalei despre viața lui Ábrahám Wald, și anume: registrul matricol de la gimnaziu piarist din Cluj și 3 scrisoari ale lui Ábrahám Wald către György Alexits în limba maghiară. Prezentarea noastră reprezintă o primă publicare autentică. La sfârșitul acestui articol accentuăm importanța de a comemora moștenirea intelectuală și materială ale lui Wald Ábrahám. Comemorarea moștenirea lui Wald ar trebui să se manifeste cu dezvăluirea unei plăci comemorativă la casa părintească a lui Wald din Cluj-Napoca. Kivonat Száz évvel Bolyai János születése után Kolozsváron született egy másik nagy, de sajnos kevébé ismert matematikus, Wald Ábrahám. Wald Ábrahám ortodox-zsidó (hasszid) családban született.

Koncepcióváltás a 19/20. század fordulóján az ipari építészetben
type: item
description: The gigantic technological development of the 19th century significantly changed the thinking of mankind and the people's attitude towards culture and art at the end of the century. Interestingly, there was also a change in the concept of form and shape in women's fashion, just as in the industrial architecture. This process of change played out in a few decades from the sometimes self-serving products that were designed purely based on formal aspects, through the adaptation in form to the opportunities and needs of the industry, to functionalism which utilized the new materials and technologies at maximum level. Rezumat Evoluţia stupefiantă a tehnicii din secolul al 19-lea, spre sfârşitul acestuia, a dus la schimbări radicale şi în privinţa gândirii, culturii şi artei umanităţii. Curios, schimbarea în formă poate fi surprinsă paralel atât în moda feminină cât şi în arhitectura industrială. Procesul de schimbare de la produsele elaborate deseori doar după criterii de forme lʼ art pour lʼart, prin cele care au luat în considerare posibilităţile şi pretenţiile industriei, până la funcţionalismul care adoptase la maximum materialele şi tehnologiile noi apărute, s-a derulat în doar câteva decenii.

A fejszámoló Bolyai Farkas
type: item
description: In his childhood, the Hungarian mathematician, Farkas Bolyai (1775–1856) was a very good mental calculator. He calculated the square and cube roots of 14-digit numbers without pen and paper. In his legacy we found an interesting, but a little bit mysterious manuscript on the cube roots. Fortunately, we understood this paper based on a Hungarian arithmetical book by Lőrincz Koretz (1805–1871). The author of this book was a piarist teacher in Hungary. This paper shows some examples based on the unknown József Farczádi Nagy’s calculations of the cube roots. Rezumat În copilărie, matematicianul maghiar Farkas Bolyai (1775–1856) a fost capabil să extragă rădăcini pătrate și cubice din numere de 14 cifre. În moștenirea sa am găsit un manuscris interesant, deși puțin misterios, despre extragerea cubică. Din fericire, descifrarea conținutului s-a reușit pe baza unei cărți de matematică a lui Lőrinc Koretz (1805–1871). Autorul acestui volum a fost un profesor piarist. Prezentul articol dicută câteva exemple bazate pe calculele necunoscute ale lui József Farczádi Nagy ale rădăcinilor cubului. Kivonat Bolyai Farkas (1775–1856) már gyermekkorában 14 jegyű számból is tudott fejben négyzet- és köbgyököt vonni. Hagyatékában egy érdekes, bár egy kicsit titokzatos kéziratot találtunk, amely a köbgyökvonásról szól. Szerencsére sikerült megfejtetni a tartalmát Koretz Lőrincz (1805–1871) egy számtankönyve alapján. E kötet szerzője kegyesrendi tanár volt. Dolgozatunk néhány példát mutat be Farczádi Nagy József köbgyökvonási módszeréről.

Ki volt a Budavári Alagút tervezője?
type: item
description: For the citizens the functionality of engineering constructions is more important than the identity of their designer. But who is the creator of an engineering construction? Is it the designer or the person who makes the plan, the intellectual work transformed into drawings, become reality? In fact, both of them are creators, but the plan is always a pre-condition of the building. The important question is whose name is remembered by the coming generations? Few people know that the designer of the Eiffel Tower (built in 1888-89) was not engineer Alexandre Gustave Eiffel (1832-1923) as many believe, but a young Alsatian-Swiss engineer working in the Eiffel Engineering Office, called Maurice Koechlin (1856-1946). He got his degree at the Zurich technical university, just as János Feketeházy who designed the majority of Hungary's bridges. Feketeházy was the designer of the Szeged downtown bridge as well, which was believed to be an Eiffel-design by the citizens for half a century, but he also designed the huge industrial complex in Budapest-Kőbánya which is known today as Eiffel-Hall, utilized by the Hungarian State Opera. According to many professional books on the topic, the Buda Castle Tunnel was built as the continuation of the Széchenyi Chain Bridge's track to make the Budapest-Déli railway station in Krisztinaváros (in Buda) easily accessible for anyone travelling from the Pest-side of the city. We know that the designer of the Chain Bridge (plans made in 1838-39) was the English engineer William Tierney Clark (1783-1852) and the construction works (cofferdam construction from 1839, bridge construction in 1842-49) were led by the Scottish engineer Adam Clark (1811-1866). We also know that after handing over the bridge to the public, Adam Clark returned to London, then after the construction of a few more bridges (Pirna, Leitmeritz, Wien) he settled down in Hungary. His last big work was the construction of the Buda Castle Tunnel (handed over on 30th April, 1857),…
