Distinguished Professor is an Honorary title at many universities for faculty who are recognized by colleagues throughout the world as leaders in their fields The meaning of the word professor ( Latin: professor, person who professes to be an expert in some art or science teacher of highest rank) varies The University of Waterloo (also referred to as UW and Waterloo) is a comprehensive Public university in the city of Waterloo, Ontario Ontario (ɒnˈtɛrioʊ is a province located in the central part of Canada, the largest by population and second largest after Quebec Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page His research is mainly in the the field of quantum chemistry. Quantum chemistry is a branch of Theoretical chemistry, which applies Quantum mechanics and Quantum field theory to address issues and problems in Among other things, he is known (together with Jiří Čížek) for the introduction of coupled cluster (CC) theory[1] in quantum chemistry and the adaptation of the CC method to electronic systems. Coupled cluster ( CC) is a numerical technique used for describing Many-body systems Its most common use is as one of several quantum chemical He also invented the unitary group approach,[2] which is an efficient way of computing Hamiltonian matrix elements over spin eigenstates that appear in electronic correlation problems. Electronic correlation refers to the interaction between Electrons in a quantum system whose Electronic structure is being considered
Paldus was born in Bzí, Czech Republic. The Czech Republic ( ˈt͡ʃɛskaː ˈrɛpuˌblɪka short form in Česko ˈt͡ʃɛskɔ also called Czechia, In 1961 he received a PhD in physical chemistry at the Czechoslovak Academy of Sciences. In 1995 he became DrSc at the Charles University in Prague and in 2006 he became Dr. H. C. at the Comenius University in Bratislava. Following the invasion of former Czechoslovakia by Warsaw pact armies in August 1968, he left his native country and became associate professor at the University of Waterloo in Canada. In 1975 he was promoted to full professor. He retired from the University of Waterloo in 2001. In 1983 Paldus was elected Fellow of the Royal Society of Canada. The Royal Society of Canada ( Société royale du Canada) now known as the RSC Academies of Arts Humanities and Sciences of Canada ( SRC Académies des Arts Since 1984 he is a member of the International Academy of Quantum Molecular Science. The International Academy of Quantum Molecular Science is an international scientific Learned society covering all applications of quantum theory to Chemistry Josef Paldus (co)authored more than 290 scientific papers.
