Radó Von Kövesligethy
Radó von Kövesligethy (in Hungarian usage, Kövesligethy Radó) (1 September 1862 in Verona, then Austrian Empire – 11 October 1934 in Budapest, Hungary), was a Hungarian physicist, astronomer and geophysicist. Kövesligethy developed a spectral equation for black body radiation for the continuous spectra of celestial bodies which had the following properties: the spectral distribution of radiation depends only on the temperature, the total irradiated energy is finite, the wavelength of the intensity maximum is inversely proportional to the temperature. His work was published in 1885 in Hungarian and in 1890 in German, 15 years before the work by Planck and eight years before Wien's work on black body radiation). Using his spectral equation, he estimated the temperature of several celestial bodies, including the Sun. He also formulated laws to establish the epicenters of earthquakes. He was an assistant to Loránd Eötvös. In 1895, he was elected as a corresponding member ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Béla Harkányi
Béla Harkányi (Baron) (; 11 April 1869 – 2 January 1932) was a Hungarian astrophysicist. Harkányi was first to determine the temperatures (in 1902) and the diameters (in 1910) of individual stars other than the Sun. Biography Harkányi was born in Budapest in a prosperous noble family. His parents were Károly Harkányi and monostori Emilia Vörös. From 1895 the family held the title of Baron. After finishing secondary school and three years of undergraduate studies in Budapest, Béla Harkányi went on to study one year in Leipzig, then in Strasbourg (teachers: F. Kohlrausch, E. Cohn, H. Kobold), occasionally visiting major astronomical institutes in Germany and the United States, including Lick Observatory. He obtained his PhD in 1896 at the Royal Hungarian University of Sciences in Budapest. Next he spent two years at the Observatory of Paris with postgraduate studies, attending, among others, Poincaré's university lectures. In the first half of 1899 he worked in t ...

19th-century Hungarian Physicists
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was Abolitionism, abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems an ...

Scientists From Verona
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hungarian Academy Of Sciences
The Hungarian Academy of Sciences ( , MTA) is Hungary’s foremost and most prestigious learned society. Its headquarters are located along the banks of the Danube in Budapest, between Széchenyi rakpart and Akadémia utca. The Academy's primary functions include the advancement of scientific knowledge, the dissemination of research findings, the support of research and development, and the representation of science in Hungary both domestically and around the world. History The origins of the Hungarian Academy of Sciences date back to 1825, when Count István Széchenyi offered one year's income from his estate to establish a ''Learned Society''. He made this offer during a session of the Diet in Pressburg (Pozsony, now Bratislava), then the seat of the Hungarian Parliament. Inspired by his gesture, other delegates soon followed suit. The Society’s mission was defined as the development of the Hungarian language and the promotion of sciences and the arts in the Hungarian l ...
