Andrzej Sołtan
Andrzej Sołtan (25 October 1897 – 10 December 1959) was a Polish nuclear physicist. He also worked on spectroscopy in the band between far ultraviolet and X-rays. During his visit to Caltech in 1932–33, together with H. Richard Crane and Charles Christian Lauritsen, he discovered a method for producing neutron beams, by bombarding lithium or beryllium nuclei with accelerated deuterons. He was appointed professor at Warsaw University in 1947, a member of the Polish Academy of Sciences in 1952, and in 1955 he became the first director of the in Świerk, Otwock County near Warsaw, now known as the National Centre for Nuclear Research. He served as president of the Polish Physical Society between 1952 and 1955. He is buried (with his wife Marta, also a physicist) in the "Avenue of the Meritorious" of Warsaw's Powązki Cemetery. The institute where he worked was renamed the Soltan Institute of Nuclear Studies in 1982. References 1897 births 1959 deaths 20th-century Poli ...

Nuclear Physics
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields such as nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Powązki Cemetery
Powązki Cemetery (; ), also known as Stare Powązki (), is a historic necropolis located in Wola district, in the western part of Warsaw, Poland. It is the most famous cemetery in the city and one of the oldest, having been established in 1790. It is the burial place of many illustrious individuals from Polish history. Some are interred along the "Avenue of the Distinguished" – ''Aleja Zasłużonych'', created in 1925. It is estimated that over one million people are buried at Powązki. The cemetery is often confused with the newer Powązki Military Cemetery, which is located to the north-west of Powązki Cemetery. History Powązki Cemetery was established on 4 November 1790 on land donated by nobleman Melchior Szymanowski, and consecrated on 20 May 1792. Initially it covered an area of only about 2.5 ha. In the same year Saint Karol Boromeusz Church, designed by Dominik Merlini, was built on the northern edge of the cemetery. The catacombs were erected soon therea ...

Deuteron
Deuterium (hydrogen-2, symbol H or D, also known as heavy hydrogen) is one of two Stable isotope ratio, stable isotopes of hydrogen; the other is protium, or hydrogen-1, H. The deuterium atomic nucleus, nucleus (deuteron) contains one proton and one neutron, whereas the far more common H has no neutrons. The name ''deuterium'' comes from Greek ''Wikt:δεύτερος, deuteros'', meaning "second". American chemist Harold Urey discovered deuterium in 1931. Urey and others produced samples of heavy water in which the H had been highly concentrated. The discovery of deuterium won Urey a List of Nobel laureates in Chemistry, Nobel Prize in 1934. Nearly all deuterium found in nature was Big Bang nucleosynthesis, synthesized in the Big Bang 13.8 billion years ago, forming the primordial ratio of H to H (~26 deuterium nuclei per 10 hydrogen nuclei). Deuterium is subsequently produced by the slow stellar proton–proton chain, but rapidly destroyed by exothermic Nuclear fusio ...
