An Etymological Dictionary of Astronomy and Astrophysics
English-French-Persian

Of an approach or study that integrates content, data, methods, tools, concepts, and theories from two or more disciplines or bodies of specialized knowledge in order to advance fundamental understanding, answer complex questions, and solve problems that are too broad or complex for a simple approach. See also → multidisciplinary and → transdisciplinary (Thompson Klein, J. 2010, Creating Interdisciplinary Campus Culture, John Wiley and Sons, Inc.).

→ inter-; → disciplinary.

1a) The sense of curiosity about or concern with something or someone.
1b) Something in which one is interested.
1c) A right, share, or claim in a business or property.
2) To engage or excite the attention or curiosity of.

M.E., from M.L. from L. interest "it concerns," from M.L. interesse "compensation for loss," noun use of L. interesse "to concern, make a difference, be of importance," literally "to be between," from → inter- "between" + esse "to be," → entity.

Andarast, coined (Adib-Soltani) on the model of the L. word, as above, from andar "between," → inter-, + ast variant hast "is, exists," → entity.

Having an interest in something; having the attention engaged; being affected or involved.

P.p. of → interest.

Inspiring interest, holding the attention.

Adj. from → interest.

1) General: A surface regarded as the common boundary of two bodies, or two parts of a system, whether material or non-material.
2) Astro.: The intersection zone between a hot → H II region and its → associated molecular cloud.
3) Chemistry: The area where two immiscible phases of a dispersion come into contact.
4) Computers: A mechanical equipment or logical program that communicates information from one system of computing devices or programs to another.

→ inter- + → face.

Physics: To cause → interference.

Interfere, from M.Fr. entreferer "to strike each other," from entre, → inter-, + ferir "to strike," from L. ferire "to knock, strike."

Andarzadan, from andar, → inter-, + zadan "to strike, beat," from Mid.Pers. zatan, žatan; O.Pers./Av. jan-, gan- "to strike, hit, smite, kill" (jantar- "smiter"); cf. Skt. han- "to strike, beat" (hantar- "smiter, killer"); Gk. theinein "to strike;" L. fendere "to strike, push;" Gmc. *gundjo "war, battle;" PIE *g^when- "to strike, kill."

The phenomenon occurring when two or more waves of the same → frequency having a constant → phase difference traverse simultaneously in the same region of a medium and cross each other. In the region of superposition, the the resulting wave intensity is different from the sum of intensities due to individual waves at that point. This phenomenon proved the validity of the wave theory of light. See also → constructive interference, → destructive interference, → interference fringe, → Young's experiment, → wave theory of light.

Interference, from → interfere + -ence a noun suffix equivalent to -ance, corresponding to the suffix -ent in adjectives.

Andarzaneš, verbal noun of andarzadan, → interfere.

A filter that uses the phenomenon of optical interferences between plane-parallel semi-transparent reflectors to transmit light selectively over a narrow wavelength band.

→ interference; → filter.

One of the alternating bright or dark bands produced by optical interference.

→ interference; → fringe.

→ order of interference.

→ interference; → order.

A wave pattern that results when two or more waves interfere with each other, generally showing → interference fringes. In acoustics, the interference pattern appear as the effect of → beats.

→ interference; → pattern.

1) Physics: A device that divides a beam of light into a number of beams and re-unites them to produce → interference. → Fabry-Perot interferometer; → Michelson interferometer.
2) Astro.: An arrangement of two or more separate telescopes placed at some distance from one another, each one receiving electromagnetic radiation (optical, infrared, or radio) from a celestial object and brought together to form an interference pattern.

Interferometer, from interfer, → interfer, + -o- a connective/euphonic infix + → -meter.

Andarzanešsanj, from andarzaneš→ interference + -sanj, → -meter.

Of or relating to → interferometry.

→ interferometer; → -ic.

A system of several telescopes coupled together in a particular configuration to carry out → interferometry.

→ interferometric; → array.

An observational technique based on principles of → interferometry.

→ interferometric; → technique.

1) The technique and study of the → interference phenomenon produced by → coherent electromagnetic waves.
2) Astro.: An observational technique that uses the interference phenomenon to substantially increase the → resolving power of telescopes.

Interferometry, from interfer, → interfer, + -o- a connective/euphonic infix + → -metry.

Of, existing, or occurring in the space between galaxies. → intergalactic absorption, → intergalactic cloud, → intergalactic matter , → intergalactic medium , → warm-hot intergalactic medium.

→ inter-; → galactic.

→ Absorption features in the spectra of bright sources like → quasars attributed to a tenuous matter filling the medium between galaxies.

→ intergalactic; → absorption.

→ Intergalactic matter in the form of clouds.

→ intergalactic; → cloud.

Very low density material found indirectly in the space between galaxies. → intergalactic absorption.

→ intergalactic; → matter.
