pân- (#), sarâsar- (#), hamé- (#)
A prefix meaning "all, whole," used as a general formative (panorama; pantelegraph; pantheism; pantonality), and especially in terms implying the union of all branches of a group (Pan-Christian; Pan-Hellenic; Pan-Slavism).
From Gk. pan-, combining form of pas (neuter pan) "all, every," of unknown origin.
Pân- loan from Gk., as above.
A system for wide-field astronomical imaging developed and operated by the Institute for Astronomy at the University of Hawaii. Its goal is to survey the sky for moving or variable objects on a continual basis, and also produce accurate astrometry and photometry of already detected objects. It is situated at Haleakala Observatories near the summit of Haleakala in Hawaii. Pan-STARRS1 (PS1) was the first part of Pan-STARRS. The survey used a 1.8 meter telescope and a 1.4 Gigapixel camera to image the sky in five broadband filters (g, r, i, z, y). The PS1 consortium is made up of astronomers and engineers from 14 institutions and six countries. The survey was completed in April 2014. The Pan-STARRS Project is now focusing on building PS2.
Short for Panoramic Survey Telescope and Rapid Response System.
A thin, flat cake of batter fried on both sides on a griddle or in a frying pan (Dictionary.com).
From M.E., from pan "a usually broad, shallow, and open container for domestic use, as for cooking;" O.E. panne + cake, from M.E., from O.N. kaka "cake," cognate with M.E. kechel "little cake;" G. Kuchen;
Lavâš "a sort of thin flattened bread."
Fr.: modèle des crêpes
A model of galaxy formation in which regions of primordial gas as massive as clusters of galaxies began to collapse into thin sheets (pancakes). Within the pancakes, smaller regions of gas later collapsed to form individual galaxies.
Fr.: étoile en crèpe
A star strongly compressed due to the → tidal force of a → massive black hole. The intense → gravity of the → black hole pulls harder on the nearest part of the star, creating an imbalance. When the star penetrates the → tidal radius, first it becomes cigar-shaped, then the squeezing of the tidal forces flattens the star in its orbital plane to the shape of a → pancake. Next the star rebounds, and as it leaves the tidal radius, it starts to expand. A little further on its orbit the star finally breaks up into gas fragments. This flattening would increase the → density and → temperature inside the star enough to trigger intense nuclear reactions that would tear it apart (Brassart & J.-P. Luminet, 2008, Astron. Astrophys. 481, 259).
One of the inner moons of Saturn and the outer shepherd moon for the F-ring. It was discovered in 1980 from Voyager 1 photos and is also known as Saturn XVII.
In Gk. mythology Pandora was the very first woman who was formed out of clay by the gods. She was bestowed upon humankind by Zeus as a punishment for Prometheus' theft of fire. Entrusted with a box containing all the ills that could plague people, she opened it out of curiosity and thereby released all the evils of human life.
Fr.: vitre, carreau
1) One of the divisions of a window or the like, consisting of a single plate of
glass in a frame. A plate of glass for such a division.
M.E. pane, pan "strip of cloth, section," from M.Fr. pan, from O.Fr. pan "section, piece, panel," from L. pannum "piece of cloth, garment;" cf. Goth. fana "piece of cloth," Gk. penos "web," O.E. fanna "flag."
Poš, from Baluci poc "cloth, clothing," from puš-, pušidan "to cover, to wear," → envelope.
Fr.: 1, 2) panneau, caisson, pan; 3) invités, experts, tribune
1) A distinct portion, section, or division of a wall, wainscot, ceiling,
door, shutter, fence, etc., especially of any surface sunk below or
raised above the general level or enclosed by a frame or border.
M.E., from O.Fr. panel "a piece (of anything)," diminutive of pan "piece of cloth or the like," ultimately from L. pannus "piece of cloth." The sense of "a small group of people called on to discuss, judge, advice on a particular matter" is from 1570s.
Hypothetical super-continent that existed from about 300 to 200 million years ago. It has since broken up and the fragments have drifted to become the configuration of Earth's present-day continents.
From Gk. → pan- "all" + gaia, variant ge "earth, land, ground, soil."
Pânzam, from → pan- + zam, variants
zamin, zami "earth, ground," from Mid.Pers. zamig "earth;"
Av. zam- "the earth;" cf. Skt. ksam; Gk. khthôn, khamai
"on the ground;" L. homo "earthly being" and humus
"the earth" (as in homo sapiens or homicide, humble, humus, exhume);
PIE root *dh(e)ghom "earth."
The hypothesis that life exists and is distributed throughout the Universe in the form of "seeds" that develop in the right environment. The oldest record of this idea may be traced back to the ancient Greek philospher Anaxagoras, who lived in the fifth century B.C.
N.L., from Gk. panspermia "mixture of all seeds," from → pan- + -sperm, a combining form of sperma "seed" + -ia a noun suffix.
Pân-dâne-vari, sarâsar-dâne-vari, from pân-, sarâsar-, → pan-, + dâné "seed, grain" (Mid.Pers. dân, dânag "seed, corn," Av. dânô- in dânô.karš- "carrying grains; an ant," Skt. dhânâ- "corn, grain," Tokharian B tâno "grain," cf. Lith. duona "corn, bread") + -var suffix of possession, variant -ur (Mid.Pers. -uwar, -war; from O.Pers. -bara, from bar- "to bear, carry") + -i noun suffix.
1) The doctrine that God is the transcendent reality of which the
material universe and human beings are only manifestations: it
involves a denial of God's personality and expresses a tendency to
identify God and nature.
1) kâqaz; 2) vetâr (#)
1) A thin sheet made from fibrous material (wood pulp, rags, straw, etc.)
suitable for writing or printing on.
From M.E. papire, from L. papyrus "paper," from Gk. papyros "any plant of the paper plant genus," may be of Egyptian origin.

âyene-ye sahmi (#)
Fr.: miroir parabolique
A concave mirror that has the form of a paraboloid of revolution.
Fr.: orbite parabolique
An orbit whose overall shape is like a parabola; it is the limiting case between an elliptical orbit (eccentricity less than 1) and a hyperbolic orbit (eccentricity larger than 1). The speed necessary to form a parabolic orbit is known as the escape velocity.
Fr.: vitesse parabolique
The speed necessary to form a parabolic orbit around a gravitational center. It is also the minimum speed necessary to escape from the gravitational pull of a body.
A solid formed by the revolution of a parabola about its axis.
