As it has turned out, however, the excessive enthusiasm in the first instance and the loss of hope in the second were both wrong responses.

The word `` binomial '' means `` of two names '' or `` of two terms '', and both usages apply in our work: the first to the names of the two outcomes of a binomial trial, and the second to the terms P and Af that represent the probabilities of `` success '' and `` failure ''.

second, that both actual and pending desegregation is, with few exceptions, the product or result of court order.

In the East abbots, if in priests ' orders and with the consent of the bishop, were, as we have seen, permitted by the second Nicene council, AD 787, to confer the tonsure and admit to the order of reader ; but gradually abbots, in the West also, advanced higher claims, until we find them in AD 1489 permitted by Innocent IV to confer both the subdiaconate and diaconate.

Individuals will arrive at both everlasting homes during Judgment Day, which commences after the Angel Israfel blows the trumpet the second time.

Hippolytus of Rome ( d. 235 ) is commonly considered to be the earliest antipope, as he headed a separate group within the Church in Rome against Pope Callixtus I. Hippolytus was reconciled to Callixtus's second successor, Pope Pontian, and both he and Pontian are honoured as saints by the Roman Catholic Church with a shared feast day on 13 August.

During this period he also completed two woodcut series, the Great Passion and the Life of the Virgin, both published in 1511 together with a second edition of the Apocalypse series.

Atomic absorption spectrometry was first used as an analytical technique, and the underlying principles were established in the second half of the 19th century by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff, both professors at the University of Heidelberg, Germany.

The second monochromator does not have an exit slit ; hence the spectral environment at both sides of the analytical line becomes visible at high resolution.

* The division of both poems into two distinct phases-a first half Odyssean phase of wandering and adventuring in a different land and a second half Iliadic phase upon taking leadership in a new kingdom and fighting a terrible enemy there.

The players change ends at the start of the second game ; if the match reaches a third game, they change ends both at the start of the game and when the leading player's or pair's score reaches 11 points.

He scored both goals in his second game as England beat Portugal 2 – 1 in a friendly at Wembley ; and overcame obvious nerves on a return to Belgrade to play his third match against Yugoslavia.

With these innings he became the second player to score two Test triple centuries, the second player to score two career quadruple centuries, the only player to achieve both these milestones, and regained the distinction of being the holder of both the record first-class individual innings and the record Test individual innings.

On the second day of battle, most of both armies had assembled.

" The Lita Grey affair was soon forgotten, but Chaplin was deeply affected by it: the stress of the ordeal turned his hair white, and both his second wife and The Circus received only a passing mention in his autobiography.

If a visible output was needed, a second tube with a phosphor coating was used as a display device.

By adjusting the intensity of the first field, it was possible to arrange it so that the luminosity of the phosphor had decayed to exactly match that of the second field, so that the two appeared to be at the same level and the film camera captured both. This method came to be preferred.

Once the plasma is fully flowing ( less than one second ), the plasma strips away the outer electrons from the mercury, sending them into the phosphor, which produces photons in the proper spectrum for tanning.

The 780 had a 21 inch CRT with a long persistence ( 2 second, nominal ) P7 phosphor.

Two astigmatic image surfaces correspond to one object plane ; and these are in contact at the axis point ; on the one lie the focal lines of the first kind, on the other those of the second.

His first aerodynamic experiments, an investigation of the air resistance of surfaces, was carried out by dropping the surface to be investigated together with a measuring apparatus down a vertical cable stretched between the second level of the Eiffel Tower and the ground.

The elements of the second homology of the del Pezzo surfaces are mapped to various BPS objects of different dimensions in M-theory.

This type of multiple texturing enhances the surfaces of objects with a second texture that shows material detail.

The paper explores the assemblies of second order hyperbolic surfaces as they are used throughout the design composition of the Sagrada Família Church building .</ ref > In his later designs, ruled surfaces are prominent in the nave's vaults and windows and the surfaces of the Passion facade.

As a result, two spectrally dissimilar lights or surfaces may produce a color match for one observer but fail to match when viewed by a second observer.

Enriques surfaces give examples of complex manifolds that have Ricci-flat metrics, but their canonical bundles are not trivial so they are Calabi – Yau manifolds according to the second but not the first definition above.

* May 23 – First flight of the second and last Grumman X-29, American experimental aircraft that tested a forward-swept wing, canard control surfaces, and other novel aircraft technologies.

The uniformization theorem implies a similar result for arbitrary connected second countable surfaces: they can be given Riemannian metrics of constant curvature.

The second includes all surfaces with vanishing Euler characteristic: the Euclidean plane, cylinder, Möbius strip, torus, and Klein bottle.

For Riemann surfaces, Rado's theorem implies that the surface is automatically second countable.

For general surfaces this is no longer true, so for the classification above one needs to assume that the surface is second countable ( or metrizable ).

In each of these cases, the transfer of q occurs as it passes through two surfaces, the first S < sub > 1 </ sub > and the second S < sub > 2 </ sub >.

Only the pitcher's mound, the home plate area, and cutouts around first, second and third bases had dirt surfaces.

Attaching bricks to one another to form walls and surfaces also reflects a second definition of modularity: namely, the use of standardized units that physically connect to each other to form larger compositions.

The sign of the second fundamental form depends on the choice of direction of ( which is called a co-orientation of the hypersurface-for surfaces in Euclidean space, this is equivalently given by a choice of orientation of the surface ).

Her avant-garde design was so radical that she and a selection of other applicants were asked to submit revised designs for a second round of competition — which she again won with " a sleek and dazzling complex of sharp lines and surfaces that she compared to an ' inverted necklace '".

They are the surfaces which, 5 times a second, lock the gear train of the watch and then transfer power to the balance wheel.

The solution of Lüroth's problem shows that for algebraic curves, rational and unirational are the same, and Castelnuovo's theorem implies that for complex surfaces unirational implies rational, because both are characterized by the vanishing of both the arithmetic genus and the second plurigenus.

In the second century, when Herodes Atticus recast an inherited villa nearby as a great landscaped estate, the natural grotto was formalized as an arched interior with an apsidal end where a statue of Egeria once stood in a niche ; the surfaces were enriched with revetments of green and white marble facings and green porphyry flooring and friezes of mosaic.
