Finite von Neumann algebra
In mathematics, a finite von Neumann algebra is a von Neumann algebra in which every isometry is a unitary. In other words, for an operator V in a finite von Neumann algebra if , then . In terms of the comparison theory of projections, the identity operator is not (Murray-von Neumann) equivalent to any proper subprojection in the von Neumann algebra.

Unitary operator
In functional analysis, a unitary operator is a surjective bounded operator on a Hilbert space that preserves the inner product.
Non-trivial examples include rotations,  reflections, and the Fourier operator.
Unitary operators generalize unitary matrices.
Unitary operators are usually taken as operating on a Hilbert space, but the same notion serves to define the concept of isomorphism between Hilbert spaces.
Obrador (surname)
Obrador or Obradors is a surname. Notable people with the surname include:

Andrés Manuel López Obrador (born 1953), president of Mexico

Fernando Obradors (1896–1945), Spanish composer

Jacqueline Obradors (born 1966), American actress

Manuela Obrador (born 1971), Mexican politician

Rafael Obrador (born 2004), Spanish footballer

Fernando Obradors
Fernando (Ferran) Jaumandreu Obradors (1896–1945) was a Spanish composer.

Obradors was taught piano by his mother, but taught himself composition, harmony and counterpoint. He became conductor of the Gran Canaria Philharmonic Orchestra, and later taught at Las Palmas Conservatory. Between 1921 and 1941 he wrote four volumes of arrangements of classic Spanish poetry, "Canciones clásicas españolas".

He is best known for the song cycle which is volume one. One of the poems, "La casada infiel", was written by his friend Federico García Lorca. Although he wrote many works for the theatre, none have held their place in the repertoire. His orchestral work "El Poema de la Jungla" is inspired by The Jungle Book stories by Rudyard Kipling. Many of his contemporaries left Spain to find fame in France, but Obradors remained true to his Catalan roots. His first surname is sometimes split into two Catalan names – Jaume Andreu.
Terbium acetylacetonate
Terbium acetylacetonate is a coordination compound with the formula Tb(C5H7O2)3. This anhydrous acetylacetonate complex is often discussed but unlikely to exist per se.  The 8-coordinated dihydrate Tb(C5H7O2)3(H2O)2 is a more plausible formula based on the behavior of other lanthanide acetylacetonates.  The dihydrate has been characterized by X-ray crystallography. Upon attempted dehydration by heating under vacuum, other hydrated lanthanide tris(acetylacetonate) complexes decompose to give oxo-clusters.  The complex can be prepared from terbium salts, acetylacetone, and a base such as ammonia.

3 NH3 + 3 Hacac + Tb(NO3)3 → Tb(acac)3 + 3 NH4NO3

It reacts with 5-[(2-thiophene methylene)amino]-8-hydroxyquinoline (L) by heating in acetonitrile/dichloromethane solution to obtain light yellow [Tb(acac)4(L)6(μ3-OH)2]·CH3CN crystals. It can be used in the preparation of some optical materials.

Dichloromethane
Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula CH2Cl2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar and miscible with many organic solvents.

Hans Reichenbach
Hans Reichenbach (/ˈraɪxənbɑːx/; German: [ˈʁaɪçənbax]; September 26, 1891 – April 9, 1953) was a leading philosopher of science, educator, and proponent of logical empiricism. He founded the Gesellschaft für empirische Philosophie (Society for Empirical Philosophy) in Berlin in 1928, also known as the "Berlin Circle". Carl Gustav Hempel, Richard von Mises, David Hilbert and Kurt Grelling all became members of the Berlin Circle.

In 1930, Reichenbach and Rudolf Carnap became editors of the journal Erkenntnis. He also made lasting contributions to the study of empiricism based on a theory of probability; the logic and the philosophy of mathematics; space, time, and relativity theory; analysis of probabilistic reasoning; and quantum mechanics. In 1951, he authored The Rise of Scientific Philosophy, his most popular book.

Philosophy of mathematics
Philosophy of mathematics is the branch of philosophy that deals with the nature of mathematics and its relationship to other areas of philosophy, particularly epistemology and metaphysics. Central questions posed include whether or not mathematical objects are purely abstract entities or are in some way concrete, and in what the relationship such objects have with physical reality consists.

Major themes that are dealt with in philosophy of mathematics include:

Reality: The question is whether mathematics is a pure product of human mind or whether it has some reality by itself.

Logic and rigor

Relationship with physical reality

Relationship with science

Relationship with applications

Mathematical truth

Nature as human activity (science, art, game, or all together)

Foelsche crater
Foelsche is a partly buried impact structure (or astrobleme), the eroded remnant of a former impact crater. It is situated about 85 km southeast of Borroloola in the Northern Territory, Australia, and named after the nearby Foelsche River. Although little of it is exposed at the surface, and no crater shaped topography is evident, the circular nature of the feature is obvious on aeromagnetic images, a factor that led to its discovery.

Aeromagnetic survey
An aeromagnetic survey is a common type of geophysical survey carried out using a magnetometer aboard or towed behind an aircraft. The principle is similar to a magnetic survey carried out with a hand-held magnetometer, but allows much larger areas of the Earth's surface to be covered quickly for regional reconnaissance. The aircraft typically flies in a grid-like pattern with height and line spacing determining the resolution of the data (and cost of the survey per unit area).
