Ioan-Ioviț Popescu
Ioan-Iovitz "Iovitzu" Popescu (October 1, 1932 – 22 December, 2023) was a Romanian physicist and linguist, emeritus professor at University of Bucharest, Faculty of Physics, and member of the Romanian Academy. In the field of physics, he is best known for his work on gas discharges and plasma physics, as well as his collaborations with Denisa Popescu in laser spectroscopy. He also had pioneering contributions in the field of gamma-ray lasers with Carl B. Collins and Silviu Olariu. As of 2006, the focus of Iovitzu Popescu's work had shifted towards the field of linguistics, in cooperation with leading linguist Gabriel Altmann. Early life Iovitzu Popescu was born in Burila Mare village, Mehedinți County. He is the son of Dumitru Popescu and Elvira (''née'' Iovitz). In 1951 he graduated from Traian High School in Turnu Severin.

Laser Spectroscopy
Spectroscopy is the field of study that measures and interprets electromagnetic spectra. In narrower contexts, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Current applications of spectroscopy include biomedical spectroscopy in the areas of tissue analysis and medical imaging. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated wit ...

Physical Review A
''Physical Review A'' (also known as PRA) is a monthly peer-reviewed scientific journal published by the American Physical Society covering atomic, molecular, and optical physics and quantum information. the editor was Jan M. Rost ( Max Planck Institute for the Physics of Complex Systems). History In 1893, the '' Physical Review'' was established at Cornell University. It was taken over by the American Physical Society (formed in 1899) in 1913. In 1970, ''Physical Review'' was subdivided into ''Physical Review A'', ''B'', ''C'', and ''D''. At that time, section ''A'' was subtitled ''Physical Review A: General Physics''. In 1990, a process was started to split this journal into two, resulting in the creation of '' Physical Review E'' in 1993. Hence, in 1993, ''Physical Review A'' changed its statement of scope to ''Atomic, Molecular and Optical Physics.'' In January 2007, the section of ''Physical Review E'' that published papers on classical optics was merged into ''Physical ...

Atomic Spectroscopy
In physics, atomic spectroscopy is the study of the electromagnetic radiation absorbed and emitted by atoms. Since unique elements have unique emission spectra, atomic spectroscopy is applied for determination of elemental compositions. It can be divided by atomization source or by the type of spectroscopy used. In the latter case, the main division is between optical and mass spectrometry. Mass spectrometry generally gives significantly better analytical performance, but is also significantly more complex. This complexity translates into higher purchase costs, higher operational costs, more operator training, and a greater number of components that can potentially fail. Because optical spectroscopy is often less expensive and has performance adequate for many tasks, it is far more common. Atomic absorption spectrometers are one of the most commonly sold and used analytical devices. Atomic spectroscopy Electrons exist in energy levels (i.e. atomic orbitals) within an atom ...

Meanwhile, an apprentices' school was founded in 1872.Pruna, p. 3 The two institutions had shut down by 1883, when their furniture and books were used to establish a new gymnasium. The first years were difficult: the school was located in several rented buildings and in the old town hall; there were a maximum of four teachers for nearly 80 students.Pruna, p. 4 A permanent building, designed by Alexandru Săvulescu, was approved in 1890.
