Schematic in the context of "Circuit diagram"

The chronology of the Bible is an elaborate system of lifespans, "generations", and other means by which the Masoretic Hebrew Bible (the text of the Bible most commonly in use today) measures the passage of events from the creation to around 164 BCE (the year of the re-dedication of the Second Temple). It was theological in intent, not historical in the modern sense, and functions as an implied prophecy whose key lies in the identification of the final event. The passage of time is measured initially by adding the ages of the Patriarchs at the birth of their firstborn sons, later through express statements, and later still by the synchronised reigns of the kings of Israel and Judah.

The chronology is highly schematic, marking out a world cycle of 4,000 years. The Exodus takes place in the year A.M. 2666 (Anno Mundi, years since the creation of the world), exactly two-thirds of the way through the 4,000-year period: the construction of Solomon's Temple commences 480 years afterward—12 generations of 40 years each—and 430 years pass between the building of Solomon's Temple and its destruction during the siege of Jerusalem. The 50 years between the destruction of the Temple and the "Decree of Cyrus" and end of the Babylonian Exile, added to the 430 years for which the Temple stood, produces another symmetrical period of 480 years. The 374 years between the Edict of Cyrus and the re-dedication of the Second Temple by the Maccabees complete the 4,000-year cycle.

A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities.

A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are generally organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography in the metaphase of the cell cycle, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as one on photomicrographs as well unless the resolution is high enough to distinguish them. The study of whole sets of chromosomes is sometimes known as karyology.

A surfactant is a chemical compound that decreases the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. The word surfactant is a blend of "surface-active agent", coined in 1950. As they consist of a water-repellent and a water-attracting part, they are emulsifiers, enabling water and oil to mix. They can also form foam, and facilitate the detachment of dirt.

Surfactants are among the most widespread and commercially important chemicals. Private households as well as many industries use them in large quantities as detergents and cleaning agents, but also as emulsifiers, wetting agents, foaming agents, antistatic additives, and dispersants.

A free neutron refers to a neutron that is not part of an atomic nucleus. When embedded in a stable nuclide, neutrons have not been observed to decay. Free neutrons, however, decay with a mean lifetime of 877.75+0.50
−0.44 s or 879.6±0.8 s (about 14 min and 37.75 s or 39.6 s, depending on the specific measurement technique). This corresponds to a half-life of 611±1 s (about 10 min, 11 s).

The free neutron decays primarily by beta decay, with small probability of other channels. Considering the most common decay and only the stable resultant products the process may be described:

The Tube map (sometimes called the London Underground map) is a schematic transport map of the lines, stations and services of the London Underground, known colloquially as "the Tube", hence the map's name. The first schematic Tube map was designed by Harry Beck in 1931. Since then, it has been expanded to include more of London's public transport systems, including the Docklands Light Railway, London Overground, the Elizabeth line, Tramlink, the London Cable Car and Thameslink.

As a schematic diagram, it shows not the geographic locations but the relative positions of the stations, lines, the stations' connective relations and fare zones. The basic design concepts have been widely adopted for other such maps around the world and for maps of other sorts of transport networks and even conceptual schematics.
