Long observation has taught Mason that most landscape can be reduced to three essential planes: a foreground in sharp focus -- either a light area with dark accents or a dark one with lights ; ;

One of the advantages of this method is that the `` pill '' can remain in the patient for several days, permitting observation under natural conditions.

Whenever the observer's learning process ( which may be a predictive neural network-see also Neuroesthetics ) leads to improved data compression such that the observation sequence can be described by fewer bits than before, the temporary interestingness of the data corresponds to the number of saved bits.

Target acquisition can take many forms, it is usually observation in real time but may be the product of analysis.

In other armies an ' authorised observer ' ( for example, artillery observation team or other target acquisition element ) can order fire units to engage.

In the latter case a battery observation team can order fire to their own battery and may be authorised to order fire to their own battalion and sometimes to many battalions.

The city can be viewed from its high observation floor.

The historic interest of the rotating bucket experiment is its usefulness in suggesting one can detect absolute rotation by observation of the shape of the surface of the water.

Classical physics draws a distinction between particles and energy, holding that only the latter exhibit waveform characteristics, whereas quantum mechanics is based on the observation that matter has both wave and particle aspects and postulates that the state of every subatomic particle can be described by a wavefunction — a mathematical expression used to calculate the probability that the particle, if measured, will be in a given location or state of motion.

Chemical kinetics experiments can then be carried out in a " pump-probe " fashion using a laser to initiate the reaction ( for example by preparing one of the reagents by photolysis of a precursor ), followed by observation of that same species ( for example by laser-induced fluorescence ) after a known time delay.

The rabbis recognize a positive value to the yetzer hara: one tradition identifies it with the observation on the last day of creation that God's accomplishment was " very good " ( God's work on the preceding days was just described as " good ") and explain that without the yetzer ha ' ra there would be no marriage, children, commerce or other fruits of human labor ; the implication is that yetzer ha ' tov and yetzer ha ' ra are best understood not as moral categories of good and evil but as selfless versus selfish orientations, either of which used rightly can serve God's will.

For example, the methodology attempts to determine the cognitive capacity of animals through observation without the necessity that this observation be regulated or controlled as in an experiment ; however, behavior in an experiment can be interpreted using the methodology.

is a philosophy which holds that reason and observation of the natural world, without the need for organized religion, can determine that the universe is the product of a creator deity.

For Deists, human beings can only know God via reason and the observation of nature, but not by revelation or supernatural manifestations ( such as miracles ) – phenomena which Deists regard with caution if not skepticism.

Garner and Rosen say that a common definition of " natural property " is one " which can be discovered by sense observation or experience, experiment, or through any of the available means of science.

Early conceptions of ecology, such as a balance and regulation in nature can be traced to Herodotus ( died c. 425 BC ), who described one of the earliest accounts of mutualism in his observation of " natural dentistry ".

* Embedding, biological specimens – after dehydration, tissue for observation in the transmission electron microscope is embedded so it can be sectioned ready for viewing.

Melodic intonation therapy was inspired by the observation that individuals with non-fluent aphasia sometimes can sing words or phrases that they normally cannot speak.

Using the following observation, one can create a recursive algorithm that computes x < sup > n </ sup > for an integer n using squaring and multiplication:

Autocorrelation can be visualized on a data plot when a given observation is more likely to lie above a fitted line if adjacent observations also lie above the fitted regression line.

To him also is due the isolation of the elements yttrium, beryllium, and titanium, the observation that " silicium " ( silicon ) can be obtained in crystals, and that some meteoric stones contain organic matter.

Alertness in humans can be determined by many kinds of verbal and non-verbal tests ; activity in animals by observation, for example of wheel-running in rodents.

For a statement to be questioned using observation, it needs to be at least theoretically possible that it can come in conflict with observation.

Following observation of the fact that the reaction rates of supposedly identical reaction mixtures prepared on the same filling manifold and exposed under identical conditions often differed by several hundred per cent, a systematic series of experiments was undertaken to see whether the difficulty could be ascribed to the method of preparing the chlorine, to the effects of oxygen or moisture or to the effect of surface to volume ratio in the reaction tubes.

Milman Parry rigorously defended the observation that the extant Homeric poems are largely formulaic, and was led to postulate that they could be shown entirely formulaic if the complete corpus of Greek epic survived ; ;

The concept that matter is composed of discrete units and cannot be divided into arbitrarily tiny quantities has been around for millennia, but these ideas were founded in abstract, philosophical reasoning rather than experimentation and empirical observation.

* Article 7 – Treaty-state observers have free access, including aerial observation, to any area and may inspect all stations, installations, and equipment ; advance notice of all activities and of the introduction of military personnel must be given ;

In one such theory, put forward by Sir E. B. Tylor, early humans initially, through mere observation, recognized what might be called a soul, life-force, spirit, breath or animus within themselves ; that which was present in the body in life and absent in death.

Of special historical interest is the observation of Abbahu in regard to the benediction " Baruk Shem Kebod Malkuto " ( Blessed be the Name of His glorious Kingdom ) after the " Shema ' Yisrael ," that in Palestine, where the Christians look for points of controversy, the words should be recited aloud ( lest the Jews be accused of tampering with the unity of God proclaimed in the Shema '), whereas in the Babylonian city of Nehardea, where there are no Christians, the words are recited with a low voice ( Pesahim 56a ).

Euan MacKie, recognizing that Thom's theories needed to be tested, excavated at the Kintraw standing stone site in Argyllshire in 1970 and 1971 to check whether the latter's prediction of an observation platform on the hill slope above the stone was correct.

However, from ground level, this sunset would be obscured by a ridge in the landscape, and the viewer would need to be raised by two meters: another observation platform was needed.

Shielded as they were from observation by a slight fold in the land, their commander, Brigadier-General Van Pallandt, ordered the regimental colours to be left in place on the edge of the plateau to convince their opponents they were still in their initial position.

Cranmer's work of simplification and revision was also applied to the Daily Offices, which were to become Morning, and Evening Prayer ; and which he hoped would also serve as a daily form of prayer to be used by the Laity, thus replacing both the late medieval lay observation of the Latin Hours of the Virgin, and its English equivalent, the Primer.

The 1928 revised forms of Matrimony and Baptism were quite widely adopted, but those of other rites tended not to be ; the consequence, in practice, being very wide variation in liturgical practice from parish to parish, with very few churchmen adhering consistently to the strict observation of either the 1662 or the 1928 forms of worship.

However none of these " alternatives " has the same breadth of explanation as inflation, and still require inflation for a more complete fit with observation ; they should therefore be regarded as adjuncts to inflation, rather than as alternatives.

The characterization is epitomized by an observation made by President Ramón Barros Luco ( 1910 – 1915 ), reputedly made in reference to labor unrest: " There are only two kinds of problems: those that solve themselves and those that can't be solved.

If this is a true observation, it may be expected that the audience which both demands and consumes this emphasis itself is more receptive to personalized, dramatic accounts of social phenomena.

One approach to understanding this process would be to study behavior through direct observation.

The theory of errors may be traced back to Roger Cotes's Opera Miscellanea ( posthumous, 1722 ), but a memoir prepared by Thomas Simpson in 1755 ( printed 1756 ) first applied the theory to the discussion of errors of observation.

The idea can be traced to Roger Bacon's observation that all languages are built upon a common grammar, substantially the same in all languages, even though it may undergo in them accidental variations, and the 13th century speculative grammarians who, following Bacon, postulated universal rules underlying all grammars.

Sometimes the dress she wears exhibits a rosetta pattern over each breast, an ancient leonine motif, which can be traced to observation of the shoulder-knot hairs on lions.

Contour lines may be either traced on a visible three-dimensional model of the surface, as when a photogrammetrist viewing a stereo-model plots elevation contours, or interpolated from estimated surface elevations, as when a computer program threads contours through a network of observation points of area centroids.

Since it is considered that the planar range extends through negative and positive infinity, close observation shows the appearance of two parallel or mirror planes in the sense that if the slope of one plane is traced, the co-plane can be seen to be bypassed or skipped, though in actuality the co-plane is also traced from the opposite perspective.

The origin of this observation is traced back:

The interest in sol-gel processing can be traced back in the mid-1980s with the observation that the hydrolysis of tetraethyl orthosilicate ( TEOS ) under acidic conditions led to the formation of SiO < sub > 2 </ sub > in the form of fibers and monoliths.
