earth

From Middle English erthe, from Old English eorþe, from Proto-West Germanic *erþu, from Proto-Germanic *erþō (“dirt, ground, earth”) (compare West Frisian ierde, German Low German Eerd, Dutch aarde, Dutch Low Saxon eerde, German Erde, Danish, Swedish and Norwegian jord), related to *erwô (“earth”) (compare Old High German ero, perhaps Old Norse jǫrfi), from Proto-Indo-European *h₁er- (compare Ancient Greek *ἔρα (*éra, “earth”) in ἔραζε (éraze, “to the ground, to earth”), perhaps Tocharian B yare (“gravel”).
Probably unrelated, but of unknown etymology, is Old Armenian երկիր (erkir, “earth”). Likewise, the phonologically similar Proto-Semitic *ʔarṣ́- – whence Arabic أَرْض (ʔarḍ), Hebrew אֶרֶץ (ʾereṣ) – is probably unrelated.

tellurian

[tʰəˈlɝː.iː.ɨ̃n]

From Latin tellūs (“earth, ground; the globe, planet Earth; country, land”), ultimately from Proto-Indo-European *telh₂- (“ground, bottom”), + -ian (suffix meaning "from, related to, or like" when forming an adjective, or "one from, belonging to, relating to, or like" when forming a noun).

It certainly appears difficult to reconcile with known facts the opinion maintained by [Carl] Linnæus and by [Thomas] Pennant, which is, indeed, a very prevalent one, that all the tribes of tellurian animals now existing have descended from a stock that was preserved in the ark of Noah.

But both from experiment and from our first principles, which remain to be more especially explained in our theory of the tellurian vortex, it is evident, that the north magnetic pole moves round the north tellurian pole, sooner than the south magnetic pole moves round the south tellurian; and this is because the distance of the two from the centre of the vortex is not similar, and because also of the spiral contorsion of the vortex.

Gaia

Borrowed from Ancient Greek Γαῖᾰ (Gaîă, “Gaea, the Earth personified as a goddess”), from γαῖᾰ (gaîă, “the Earth”), probably related to γῆ (gê, “earth, land; country”).
Sense 1 was coined by the British scientist, environmentalist, and futurist James Lovelock (1919–2022) in his book Gaia: A New Look at Life on Earth (1979), at the suggestion of the British novelist, playwright, and poet William Golding (1911–1993): see the quotation.

[page 1] As I write, two Viking spacecraft are circling our fellow planet Mars, awaiting landfall instructions from the Earth. Their mission is to search for life, or evidence of life, now or long ago. This book is also about a search for life, and the quest for Gaia is an attempt to find the largest living creature on Earth. […] [I]f Gaia does exist, then we may find ourselves and all other living things to be parts and partners of a vast being who in her entirety has the power to maintain our planet as a fit and comfortable habitat for life. […] [page 11] We have since defined Gaia as a complex entity involving the Earth's biosphere, atmosphere, oceans, and soil; the totality constituting a feedback or cybernetic system which seeks an optimal physical and chemical environment for life on this planet.

1979, J[ames] E[phraim] Lovelock, “Introductory”, in Gaia: A New Look at Life on Earth, Oxford: Oxford University Press, →ISBN, pages 1 and 11:

If we are all—from the lowliest microorganism to the largest whale—a part of Gaia, then we are all potentially important to its well-being. Therefore, the ecologists who deplore the elimination of a species are not merely appealing to our sentiment. They are warning us, often without knowing it, about a blind and dangerous tinkering with the mechanism of the world. It is not enough just to regret the extinction of a whale, or even of the smallpox virus. When we delete one of these from Gaia's catalog, we may have destroyed part of ourselves. We are also a part of Gaia.

1980 July, James E. Lovelock, “Living Planet Earth”, in Omni, volume 2, number 10, →ISSN, →OCLC, page 124, column 3:

In fact Planet Earth can be seen as an active participant in the creation of its own story, a living being now given the name Gaia, a name from Greek mythology for the goddess of earth. […] The very ability to perceive of the earth as living, as Gaia, is an indication of the expansion of consciousness that humanity as a whole is experiencing.

Having recognised the Gaian phenomenon I would like to explain where I think Gaia comes from and ask for how long this Gaia phenomenon has persisted on the surface of the Earth. And then I would like to raise some of the objections to the Gaia hypothesis.

sublunary

PIE word
 *upó
The adjective is a learned borrowing from Late Latin sublūnāris (“sublunar, sublunary”) + English -ary (suffix meaning of or pertaining to forming adjectives). Sublūnāris is derived from Latin sub- (prefix meaning ‘below, beneath, under’) + lūnāris (“of or pertaining to the moon, lunar”) (from lūna (“moon”) (ultimately from Proto-Indo-European *lewk- (“bright; to see; to shine”)) + -āris (suffix forming adjectives denoting a pertaining to or relationship)). By surface analysis, sub- + lunary.
The noun is derived from the adjective.

geoid

From German Geoid (“geoid”), analysable as geo- + -oid.

The problem of the form and dimensions of the sea level surface of the earth has been one of peculiar difficulty. The combined efforts of the ablest mathematicians of the past two centuries, supplemented by the most laborious and costly geodetic measurements have yielded us the first approximation only to the complete solution. […] This spheroid, or reference ellipsoid, as it is sometimes called, has its minor axis coincident with the earth's axis of rotation and is usually regarded as sensibly fixed in position and dimensions. With respect to it the actual sea surface or geoid must be imagined to lie partly above and partly below by small but unknown amounts, the determination of which, if possible, will constitute a second approximation to the figure of the earth.

In an earlier paper at Berkeley last year [Durbin, 1963], I suggested correlations between the local crust and the corresponding geoid undulation.

This paper deals with the accuracy of a geoid computed using local gravity data supplemented by a global potential model. Local gravity can only correct the global model for wavelengths less than about one third of the dimension of local data, so any longer wavelength errors in the global geoid remain in the local model.

Earth-grazing

How many [orbital periods] are there in a year for an Earth-grazing satellite? Since the time of Sputnik (October 4, 1957), it has been familiar that a satellite in a low orbit revolves about the Earth in about 90 minutes. That period would be 84 minutes for the hypothetical Earth-grazing satellite.

The ‘Earth grazing’ asteroid Hermes was photographically discovered by [Karl Wilhelm] Reinmuth on October 28th 1937. It came to within nearly 500 000 miles (800 000 km) of the Earth which is less than double the distance that separates the Earth from the moon. On October 30th 1937 Hermes, which was of the 8th magnitude, sped path the Earth at an angular pace in the sky of 5° per hour, so fast that its distance could not be deduced by using the usual mathematical methods. Instead it had to be calculated from its parallax as seen from two different observatories. It was ‘lost’ in 1937.

It and the Earth were supposed to have a parallel concentric movement; it was an idea devised to spare the Earth, which was supposed to perform around the central fire a planetary revolution in 24 hours, from having also to execute a movement of rotation, and, indead, represented no doubt the opposite hemisphere, or the antipodal half of our planet.

1852, Alexander von Humboldt, Cosmos: Sketch of a Physical Description of the Universe:

For the later Pythagoreans the world was made up of four elements: earth, water, air, and fire; the universe had a spherical earth traveling around in a circle once every 24 hours (instead of rotating); there was an invisible central fire, with the sun reflecting light from it; and in order to have exactly 10 major bodies in the universe, there was stipulated an antiearth, visible only from the back of the earth.

1972, Dietrich Schroeer, Physics and its fifth dimension: society, page 63:

As for the planet high up to the right in the sky, I have not managed to ascertain whether it is a product of the Pythagorean Antiearth, or of the sentiment laid in my soul by the radiation of Planck's 'Black Body'

1992, Alberto Savinio, Alberto Savinio: paintings and drawings, 1925-1952, page 112:

Directly opposite the oikoumene was the "antichthones," or "opposite land," or "antiearth," also called the "periocci." It corresponded to the quarter of the globe North America occupies, and its night and day were the reverse of the oikoumene.

1998, Ronald H. Fritze, Travel Legend and Lore: An Encyclopedia, →ISBN, page 17:

(historical) A hypothetical twin planet to earth, proposed by the Pythagoreans, which cannot be seen from earth.


antiearth

If particles that originally occupy a box which is 20RE long in the earth-antiearth direction and 10Rf wide perpendicular to the neutral sheet leak out of a slit of 4Rf wide with a speed of 400 km/s, it takes 800s before all the particles are lost.

1984, Edward W. Hones, Magnetic Reconnection in Space and Laboratory Plasmas:

The Rx antenna has a single hinge line and during launch the reflector dish is restrained against the antiearth panel by two hold-down points.

1985, STAR, an Abstract Journal - Volume 23, Issues 5-8, page 628:

Overview of LUCE The optical part of LUCE (LUCE-O) is installed on the plane of antiearth direction of OICETS for wide visibility of the geo-stationary satellite, ARTEMIS.

1995, Free-space Laser Communication Technologies:

One thought that much of curricula currently taught, including math and science, could be construed as antiearth, and that students need to feel they are being affected personally in order to be mobilized to action.

1992, Building A Shared Vision For Environmental Education, →ISBN, page 99:

They see these manifestations of a patriarchal biased mentality as antifeminist, antihuman and antiearth.

1995, Michael E. Salla, Walter Tonetto, Enrique Martínez, Essays on Peace: Paradigms for Global Order, →ISBN, page 80:

We were at a similar historical point at the turn of this century. The hesitation stage. A passing phase. On the side of the old, the Cassandras of the National Idea. On the new, us! Unreasonable wanderers in an antibody era, antiearth, antiflesh, hiding ourselves out of timidity, joyous because we were desperate, at home with our bodies, but without borders, ironic because unsure, nostalgic not of the past that is no more, but for a future that could be.

Opposed to or destructive of the earth and things native to the earth.

overview effect

overview effect (plural overview effects)

Coined by writer Frank White to describe the experience of astronauts when they see the Earth from space.

The transcendental change of perception when one can view the Earth, or any other planetary object, within the universal context.


there is no Planet B

Coined by British comedian and writer Rob Newman in 2006, in his stage show There Is No Planet B: A history of the world backwards. In 2007, Newman performed a song called No Planet B at Heathrow Climate Camp, after which activists painted the phrase on placards, first at the Heathrow Climate Camp, and then at COP15 in Copenhagen. The phrase was later popularized by British researcher and writer Mike Berners-Lee in his 2019 book There Is No Planet B: A Handbook for the Make or Break Years. It is a play on words based on the phrase "there is no plan B".
