Short Definition:

A usually massive iron-black mineral that consists of an oxide of iron and titanium and that is a major titanium ore.


Detailed Definition:

Ilmenite is named after the Ilmenski mountains in Russia, where the mineral was first discovered. It is slightly magnetic, which means that magnets can be used to separate it from other minerals in sand deposits. Ilmenite is also a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. Also, it is a black iron-titanium oxide with a chemical composition of FeTiO3. 


Etymology:

Named after Ilmen Mountains in Russia +‎ -ite in 1827. 

The suffix –ite is used to form nouns denoting rocks or minerals, from Latin -ītēs, and from Ancient Greek -ῑ́της.


Sample Sentences:

"Ilmenite is an economically important and interesting mineral."

"Ilmenite is the most important ore of titanium and the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics."

Definition:

Rapid expansion of the universe at its early stages of development (at around 10-36 seconds after the Big Bang).

The Inflation Theory was developed in 1980 by Alan Guth, Andrei Linde, Paul Steinhardt, and Andy Albrecht and attempted to account for phenomena that could not be explained by the Big Bang Theory (the Horizon Problem, the Flatness Problem and the Monopole Problem). Nowadays, the Inflation Theory is considered to be an extension of the Big Bang Theory.

Short Definition:

Light with wavelength from 800 nanometers to 1 millimiter.

Detailed Definition:

Electromagnetic radiation with wavelengths ranging from 800 nanometers to one millimeter. It is next to the red end of the visible spectrum, hereby the name. Also called IR, it is a kind of electromagnetic radiation that has qualities like both a wave and a particle, the photon, and propagates energy and momentum as well as exerting radiation pressure.

Etymology:

Infrared comes from Latin: infra, which means below.

Sample Sentence(s):

To keep an eye on workplace activities, they used infrared cameras.

Without disturbing the bats, an infrared camera records them.

Initial mass function (IMF)

Plot initial mass function with different alpha values

Short Definition:

The initial mass function (IMF) describes the distribution of stellar masses as a large cluster of stars is newly formed and is based on an average from stars in our Milky Way.

This function is useful for understanding the formation of stellar systems and their evolution. In most cases, the initial mass function is shown with a logarithmic scale.

Derailed Definition:

The initial mass function shows few massive stars which are more massive than the sun, while sun-sized stars are more abundant and stars that are smaller than the sun are quite common (this trend does not continue linear the smaller they get):

The function can be described by using the following law:

IMF = constant x m^(-α)

where m = initial star mass and α = slope of the logarithmic plot.

Until this point in time, it is not certain if the IMF varies in extreme situations and if the calculation based on our Milky Way can be unconditionally applied to other galaxies.


Etymology:

initial - Latin initialis ("initial, incipent, of the beginning")

mass - old French masse (" lump, heap, pile; crowd, large amount")

function - Latin functionem (" a performance, an execution")


Sample sentences:

There are different curve forms of the initial mass function based on the way the alpha and the constant are calculated.


Translation:

French: fonction de masse initiale

German: Anfangsmassenfunktion

Polish:początkowafunkcjamasy

Swedish: funktion för dem ursprungliga massan

Definition:

A research facility that was launched in 1998, is orbiting around the Earth and is operated by multinational groups of astronauts sent regularly by five space agencies participating in the project – NASA (the USA), Roscosmos (Russia), ESA (Europe), JAXA (Japan) and CSA (Canada).
