Theremin
The theremin (; originally known as the ætherphone/etherphone, thereminophone or termenvox/thereminvox) is an electronic musical instrument controlled without physical contact by the performer (who is known as a thereminist). It is named after its inventor, Leon Theremin, who patented the device in 1928. The instrument's controlling section usually consists of two metal antenna (radio), antennas which sense the relative position of the thereminist's hands and control oscillation, oscillators for frequency with one hand, and amplitude (Loudness, volume) with the other. The electric signals from the theremin are amplifier, amplified and sent to a loudspeaker. The sound of the instrument is often associated with wikt:eerie, eerie situations. The theremin has been used in movie soundtracks such as Miklós Rózsa's ''Spellbound (1945 film), Spellbound'' and ''The Lost Weekend (film), The Lost Weekend'', Bernard Herrmann's ''The Day the Earth Stood Still (soundtrack), The Day the E ...

Ivan Pavlov
Ivan Petrovich Pavlov ( rus, Ива́н Петро́вич Па́влов, , p=ɪˈvan pʲɪˈtrovʲɪtɕ ˈpavləf, a=Ru-Ivan_Petrovich_Pavlov.ogg; 27 February 1936), was a Russian and Soviet experimental neurologist, psychologist and physiologist known for his discovery of classical conditioning through his experiments with dogs. Education and early life Ivan Petrovich Pavlov, the first of eleven children, was born in Ryazan, Russian Empire. His father, Peter Dmitrievich Pavlov (1823–1899), was a village Russian orthodox priest. His mother, Varvara Ivanovna Uspenskaya (1826–1890), was a devoted homemaker. As a child, Pavlov willingly participated in house duties such as doing the dishes and taking care of his siblings. He loved to garden, ride his bicycle, row, swim, and play gorodki; he devoted his summer vacations to these activities. Although able to read by the age of seven, Pavlov was seriously injured when he fell from a high wall onto a stone pavement. As a resul ...

X-ray Crystallography
X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their crystallographic disorder, and various other information. Since many materials can form crystals—such as salts, metals, minerals, semiconductors, as well as various inorganic, organic, and biological molecules—X-ray crystallography has been fundamental in the development of many scientific fields. In its first decades of use, this method determined the size of atoms, the lengths and types of chemical bonds, and the atomic-scale differences among various mat ...

Max Laue
Max Theodor Felix von Laue (; 9 October 1879 – 24 April 1960) was a German physicist who received the Nobel Prize in Physics in 1914 for his discovery of the diffraction of X-rays by crystals. In addition to his scientific endeavors with contributions in optics, crystallography, quantum theory, superconductivity, and the theory of relativity, Laue had a number of administrative positions which advanced and guided German scientific research and development during four decades. A strong objector to Nazism, he was instrumental in re-establishing and organizing German science after World War II. Biography Early years Laue was born in Pfaffendorf, now part of Koblenz, Germany, to Julius Laue and Minna Zerrenner. In 1898, after passing his '' Abitur'' in Strassburg, he began his compulsory year of military service, after which in 1899 he started to study mathematics, physics, and chemistry at the University of Strassburg, the University of Göttingen, and the Ludwig Maximili ...

Ioffe Institute
The Ioffe Physical-Technical Institute of the Russian Academy of Sciences (for short, Ioffe Institute, russian: Физико-технический институт им. А. Ф. Иоффе) is one of Russia's largest research centers specialized in physics and technology. The institute was established in 1918 in Petrograd (now St. Petersburg) and run for several decades by Abram Ioffe. The institute is a member of the Russian Academy of Sciences. Present structure of the institute As of 2019, the Ioffe institute employed about 1500 people, around 1000 of whom were scientific researchers (including 560 with a PhD degree and 250 with a Doktor Nauk degree). Most of the research staff members are top graduates of the St. Petersburg (former Leningrad) universities. From 2013 until mid-May 2018 the Ioffe institute was under formal jurisdiction of the Federal Agency for Scientific Organizations (FASO Russia), now it is under jurisdiction of the established in May 2018 Ministry of Sc ...
