His first " continuous tension – discontinuous compression " geodesic dome ( full sphere in this case ) was constructed at the University of Oregon Architecture School in 1959 with the help of students.

However, the data he used originated back to epoch B1875. 0, which was when Benjamin A. Gould first made the proposal to designate boundaries for the celestial sphere, a suggestion upon which Delporte would base his work.

The central atoms or ion and the donor atoms comprise the first coordination sphere.

Dyson is credited with being the first to formalize the concept of the Dyson sphere in his 1960 paper " Search for Artificial Stellar Sources of Infra-Red Radiation ", published in the journal Science.

The " One " is further separated into spheres of intelligence ; the first and superior sphere is objects of thought, while the latter sphere is the domain of thought.

His other reputed achievements include the discovery of Earth's precession, the compilation of the first comprehensive star catalog of the western world, and possibly the invention of the astrolabe, also of the armillary sphere, which he used during the creation of much of the star catalogue.

This was the first atlas to cover the entire celestial sphere.

In September 2002, researchers at the Los Alamos National Laboratory briefly created the first known nuclear critical mass using neptunium in combination with shells of enriched uranium ( U-235 ), discovering that the critical mass of a bare sphere of neptunium-237 " ranges from kilogram weights in the high fifties to low sixties ," showing that it " is about as good a bomb material as U-235.

In discussing the work of Pytheas, Strabo typically uses direct discourse: " Pytheas says ..." In presenting his astronomical observations, he changes to indirect discourse: " Hipparchus says that Pytheas says ..." either because he never read Pytheas ' manuscript ( because it was not available to him ) or in deference to Hipparchus, who appears to have been the first to apply the Babylonian system of representing the sphere of the earth by 360 °.

The Poincaré sphere was the first example of a homology sphere, a manifold that had the same homology as a sphere, of which many others have since been constructed.

It is, indeed, presented as the second part of the study of astronomy of which the Almagest was the first, concerned with the influences of the celestial bodies in the sublunar sphere.

He fashioned first an armillary sphere.

Redstockings co-founder Ellen Willis wrote in 1984 that radical feminism " got sexual politics recognized as a public issue ", " created the vocabulary … with which the second wave of feminism entered popular culture ", " sparked the drive to legalize abortion ", " were the first to demand total equality in the so-called private sphere " (" housework and child care ,… emotional and sexual needs "), and " created the atmosphere of urgency " that almost led to the passage of the Equal Rights Amendment.

The Borg sphere fires on the planet ; realizing that the Borg are trying to prevent first contact, the Enterprise crew destroy the sphere and send an away team to the Montana site where Cochrane is building his ship, the Phoenix, to look for survivors.

This formula was first derived by Archimedes, who showed that the volume of a sphere is 2 / 3 that of a circumscribed cylinder.

#: The first part is the usual definition of the sphere and determines it uniquely.

Consider now the acceleration due to the sphere of mass M experienced by a particle in the vicinity of the body of mass m. With R as the distance from the center of M to the center of m, let ∆ r be the ( relatively small ) distance of the particle from the center of the body of mass m. For simplicity, distances are first considered only in the direction pointing towards or away from the sphere of mass M. If the body of mass m is itself a sphere of radius ∆ r, then the new particle considered may be located on its surface, at a distance ( R ± ∆ r ) from the centre of the sphere of mass M, and ∆ r may be taken as positive where the particle's distance from M is greater than R. Leaving aside whatever gravitational acceleration may be experienced by the particle towards m on account of ms own mass, we have the acceleration on the particle due to gravitational force towards M as:

Even the knowledge that she was losing another boy, as a mother always does when a marriage is made, did not prevent her from having the first carefree, dreamless sleep that she had known since they dropped down the canyon and into Bear Valley, way, way back there when they were crossing those other mountains.

Life is further characterized, in antithesis to Piepsam, as animal: the image of a dog, which appears at several places, is first given as the criterion of amiable, irrelevant interest aroused by life considered simply as a spectacle: a dog in a wagon is `` admirable '', `` a pleasure to contemplate '' ; ;

In the first instance, `` mimesis '' is here used to mean the recalling of experience in terms of vivid images rather than in terms of abstract ideas or conventional designations.

This is the primary function of the imagination operating in the absence of the original experiential stimulus by which the images were first appropriated.

The first half of The Charles Men, ending on the climax of the battle of Poltava in 1709, is more dramatically coherent than the second.

He is, first and foremost, a defender of public morals, a servant of society.

The first of two possible variations on this theme is symbolized by Mickey Spillane's Mike Hammer.

Noting such evidence is the first step ; ;

So it is that we relive his opening statement in the first television address with the dramatic immediacy of the present.

and it is surely clear that the first of these is the result of the way in which the individual's command of language interacts with the other two.

The first thing to do is get her some money by a temporary but definite adjustment pending a final disposition of the case.

When I take over Taliesin, the first thing I'll do is fire you ''.

If `` Jack the Courtier '' is really to be taken as Swift, the following remark is obviously Steele's comment on Swift's change of parties and its effect on their friendship: `` I assure you, dear Jack, when I first found out such an Allay in you, as makes you of so malleable a Constitution, that you may be worked into any Form an Artificer pleases, I foresaw I should not enjoy your Favour much longer ''.

At this point a working definition of idea is in order, although our first definition will have to be qualified somewhat as we proceed.

`` History has this in common with every other science: that the historian is not allowed to claim any single piece of knowledge, except where he can justify his claim by exhibiting to himself in the first place, and secondly to any one else who is both able and willing to follow his demonstration, the grounds upon which it is based.

We saw it frequently afterward, but our suggestion for the very first encounter is near sunset.

Master Gorton, having foully abused high and low at Aquidneck is now bewitching and bemaddening poor Providence, both with his unclean and foul censures of all the ministers of this country ( for which myself have in Christ's name withstood him ), and also denying all visible and external ordinances in depth of Familism: almost all suck in his poison, as at first they did at Aquidneck.

The Ionian School of philosophers were the first natural philosophers ( φυσιολόγοι: physiologoi ) who tried to explain phenomena according to non-supernatural laws, and Pythagoras introduced the abstract mathematical-relations which formed the basis of the science of mathematics.

The concept of an abelian group is one of the first concepts encountered in undergraduate abstract algebra, with many other basic objects, such as a module and a vector space, being its refinements.

The first is focused on abstract mental functions of an intelligent mind and operates using symbols, and the second, which follows the neural and associative properties of the human brain, is called subsymbolic.

The middot seem to have been first laid down as abstract rules by the teachers of Hillel, though they were not immediately recognized by all as valid and binding.

Whilst Schwitters still created work in an expressionist style into 1919 ( and would continue to paint realist pictures up to his death in 1948 ), the first abstract collages, influenced in particular by recent works by Hans Arp, would appear in late 1918, which Schwitters dubbed Merz after a fragment of found text from the sentence Commerz Und Privatbank in his picture Das Merzbild, Winter 1918 – 19.

The book is divided into three parts reflecting this: the first on chess ( a game purely of abstract strategy ), the second on dice ( with outcomes controlled strictly by chance ), and the last on tables ( combining elements of both ).

Linear algebra first took its modern form in the first half of the twentieth century, when many ideas and methods of previous centuries were generalized as abstract algebra.

Thus, in the first twenty years of the 20th century many writers, thinkers, and artists broke with the traditional means of organizing literature, painting, and music ; the results were abstract art, atonal music, and the stream of consciousness technique in the novel.

These " modernist " landmarks include the atonal ending of Arnold Schoenberg's Second String Quartet in 1908, the expressionist paintings of Wassily Kandinsky starting in 1903 and culminating with his first abstract painting and the founding of the Blue Rider group in Munich in 1911, and the rise of fauvism and the inventions of cubism from the studios of Henri Matisse, Pablo Picasso, Georges Braque and others in the years between 1900 and 1910.

In 1911, Kandinsky painted Bild mit Kreis ( Picture With a Circle ) which he later called the first abstract painting.

The continuation of abstract expressionism, color field painting, lyrical abstraction, geometric abstraction, minimalism, abstract illusionism, process art, pop art, postminimalism, and other late 20th-century modernist movements in both painting and sculpture continue through the first decade of the 21st century and constitute radical new directions in those mediums.

While the first factor, which describes the bulk of the variation in a set of data, is more likely to represent something objectively real, subsequent factors become more and more abstract.

" He was the first to offer a combination of abstract entities of classical culture and Christian philosophy.

He was first to assign a fundamental place for algebra in our system of knowledge, and believed that algebra was a method to automate or mechanize reasoning, particularly about abstract, unknown quantities.

Some of Aristotle's Categories are included in Roget's first class " abstract relations ".

" The first is the fallacy of " reification ", which is " our tendency to convert abstract concepts into entities " such as the intelligence quotient ( IQ ) and the general intelligence factor ( g factor ), which have been the cornerstones of much research into human intelligence.

He is credited with painting the first purely abstract works.

Sadleir's interest in Kandinsky also led to Kandinsky's first works entering a British art collection ; Sadleir's father, Michael Sadler, acquired several woodprints and the abstract painting Fragment for Composition VII in 1913 following a visit by father and son to meet Kandinsky in Munich that year.

Subsequently, representations are gradually organized into logical structures which first operate on the concrete properties of the reality, in the stage of concrete operations, and then operate on abstract principles that organize concrete properties, in the stage of formal operations.

His first abstract works were made in 1917.
