Sir Karl Raimund Popper was an Austrian–British philosopher, academic and social commentator. One of the 20th century's most influential philosophers of science, Popper is known for his rejection of the classical inductivist views on the scientific method in favour of empirical falsification. According to Popper, a theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can be scrutinised with decisive experiments. Popper was opposed to the classical justificationist account of knowledge, which he replaced with critical rationalism, namely "the first non-justificational philosophy of criticism in the history of philosophy".

Migmatite is a composite rock found in medium and high-grade metamorphic environments, commonly within Precambrian cratonic blocks. It consists of two or more constituents often layered repetitively: one layer is an older metamorphic rock that was reconstituted subsequently by partial melting ("neosome"), while the alternate layer has a pegmatitic, aplitic, granitic or generally plutonic appearance ("paleosome"). Commonly, migmatites occur below deformed metamorphic rocks that represent the base of eroded mountain chains.

HSwMS <i>Ehrensköld</i> (11)

HSwMS Ehrensköld (11), was the lead ship of her class of destroyer in the Swedish Navy during World War II. Together with the sister ship HSwMS Nordenskjöld (12), she constituted the Ehrensköld class, which, with its size and speed, was a major step in the Swedish destroyer fleet. Initially, Ehrensköld had pennant number 11, which was later changed to 1. In 1951-1952, the ship was converted to frigate, and then received the pennant number 71. She was decommissioned in 1963 and was sold for scrapping in 1973.

Lumbriculus genitosetosus was described by Holmquist in 1976 from almost 2,000 individuals collected in Northern Alaska. Initially, Holmquist revived the genus Thinodrilus for L. genitosetosus, Lumbriculus inconstans and Lumbriculus ambiguus on the basis of the Lumbriculus-species having only one pair of vas deferens and sperm funnels per atrium, whereas the Thinodrilus-species have two ; this division is, however, not generally recognised today, even if Thinodrilus may be a valid subgenus.

In solid mechanics, the Johnson–Holmquist damage model is used to model the mechanical behavior of damaged brittle materials, such as ceramics, rocks, and concrete, over a range of strain rates. Such materials usually have high compressive strength but low tensile strength and tend to exhibit progressive damage under load due to the growth of microfractures.
