Karol Olszewski
Karol Stanisław Olszewski (Polish pronunciation: ; 29 January 1846 – 24 March 1915) was a Polish chemist, mathematician, and physicist. Together with Zygmunt Wróblewski, in 1883 he was the first scientist in the world to liquify oxygen and nitrogen. Life and career He was born in 1846 in Broniszów. He was a graduate of Kazimierz Brodziński High School in Tarnów (I Liceum Ogólnokształcące im. Kazimierza Brodzińskiego). He studied at Kraków's Jagiellonian University in the departments of mathematics and physics, and chemistry and biology. He carried out his first experiments using a personally improved compressor, compressing and condensing carbon dioxide. Olszewski defended his doctoral dissertation at Heidelberg University, then returned to Kraków, where he was made ''profesor nadzwyczajny'' (associate professor). In 1883, Zygmunt Wróblewski and Karol Olszewski were the first in the world to liquefy oxygen, nitrogen and carbon dioxide from the atmosphere in a ...

Hydrogen
Hydrogen is a chemical element; it has chemical symbol, symbol H and atomic number 1. It is the lightest and abundance of the chemical elements, most abundant chemical element in the universe, constituting about 75% of all baryon, normal matter. Under standard conditions, hydrogen is a gas of diatomic molecules with the chemical formula, formula , called dihydrogen, or sometimes hydrogen gas, molecular hydrogen, or simply hydrogen. Dihydrogen is colorless, odorless, non-toxic, and highly combustible. Stars, including the Sun, mainly consist of hydrogen in a plasma state, while on Earth, hydrogen is found as the gas (dihydrogen) and in molecular forms, such as in water and organic compounds. The most common isotope of hydrogen (H) consists of one proton, one electron, and no neutrons. Hydrogen gas was first produced artificially in the 17th century by the reaction of acids with metals. Henry Cavendish, in 1766–1781, identified hydrogen gas as a distinct substance and discovere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marian Danysz
Marian Danysz (March 17, 1909 – February 9, 1983) was a Polish physicist, Professor of Physics at Warsaw University. Son of Jan Kazimierz Danysz. In 1952, he co-discovered with Jerzy Pniewski a new kind of matter, an atomic nucleus, which alongside a proton and neutron contains a third particle: the lambda hyperon In particle physics, a hyperon is any baryon containing one or more strange quarks, but no charm, bottom, or top quarks. This form of matter may exist in a stable form within the core of some neutron stars. Hyperons are sometimes generically re ... (). Ten years later, they obtained a hypernucleus in excited state, and the following year a hypernucleus with two lambda hyperons.

Jerzy Pniewski
Jerzy Pniewski (Polish: ; June 1, 1913 – June 16, 1989) was a Polish physicist, professor at the University of Warsaw and a member of the Polish Academy of Sciences. He is best known for discovering the hypernucleus together with Marian Danysz in 1952. Life and career Pniewski was born in 1913 in Płock, Congress Poland. He studied mathematics and physics at the University of Warsaw. He served as Director at the Institute of Experimental Physics of the University of Warsaw between 1953–1958 and 1962–1975 and subsequently as Head of the Department of Physics from 1975 to 1981. In the 1950s, he enabled his physics students to work at CERN, who were officially unable to participate in this project due to political reasons at that time. His contributions to science are in the area of subatomic experimental physics, in particular nuclear physics. In 1952, he co-discovered the hypernucleus with Marian Danysz. The discovery was made with the use of a nuclear emulsion pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marian Smoluchowski
Marian Smoluchowski (; 28 May 1872 – 5 September 1917) was a Polish physicist who worked in the territories of the Austro-Hungarian Empire. He was a pioneer of statistical physics and made significant contributions to the theory of Brownian motion and stochastic processes. Smoluchowski graduated in physics from the University of Vienna in 1895 before becoming a '' privatdozent'' at the University of Lemberg three years later. In 1913, he was appointed the chair of the Faculty of Experimental Physics at the Jagellonian University in Kraków. He is known for the Smoluchowski equation, Einstein–Smoluchowski relation and Feynman–Smoluchowski ratchet. Life He was born in 1872 into an upper-class family in Vorder-Brühl, near Vienna, to father Wilhelm and mother Teofila (née Szczepanowska). He attended the prestigious Collegium Theresianum and subsequently studied physics at the University of Vienna (1890-95). In 1895, he obtained his doctorate based on his disser ...

X-ray
An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays. Roughly, X-rays have a wavelength ranging from 10 Nanometre, nanometers to 10 Picometre, picometers, corresponding to frequency, frequencies in the range of 30 Hertz, petahertz to 30 Hertz, exahertz ( to ) and photon energies in the range of 100 electronvolt, eV to 100 keV, respectively. X-rays were discovered in 1895 in science, 1895 by the German scientist Wilhelm Röntgen, Wilhelm Conrad Röntgen, who named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . X-rays can penetrate many solid substances such as construction materials and living tissue, so X-ray radiography is widely used in medical diagnostics (e.g., checking for Bo ...

Wilhelm Röntgen
Wilhelm Conrad Röntgen (; 27 March 1845 – 10 February 1923), sometimes Transliteration, transliterated as Roentgen ( ), was a German physicist who produced and detected electromagnetic radiation in a wavelength range known as X-rays. As a result of this discovery, he became the first recipient of the Nobel Prize in Physics in 1901.Novelize, Robert. ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th ed. 1997. p. 1. Biographical history Education Röntgen was born in Lennep on 27 March 1845 to Friedrich Conrad Röntgen, a German merchant and cloth manufacturer, and Charlotte Constanze Frowein.
