Because geodetic point coordinates ( and heights ) are always obtained in a system that has been constructed itself using real observations, geodesists introduce the concept of a geodetic datum: a physical realization of a coordinate system used for describing point locations.

Because political science is essentially a study of human behavior, in all aspects of politics, observations in controlled environments are often challenging to reproduce or duplicate, though experimental methods are increasingly common ( see experimental political science ).

Because the stars were all born at roughly the same time, the different properties of all the stars in a cluster are a function only of mass, and so stellar evolution theories rely on observations of open and globular clusters.

Because of their lack of interaction with normal matter, they would be dark and invisible through normal electromagnetic observations.

Because the observations are independent, this can be written as

Because the observations are independent, the pdf can be written as a product of individual densities

Because the quantum efficiency of Hubble's detectors is quite low at 300 nm, the noise in observations at this wavelength is primarily due to CCD noise rather than sky background ; thus, these observations could be conducted at times when high background noise would have harmed the efficiency of observations in other passbands.

Because the wavelengths at which the images were taken do not correspond to the wavelengths of red, green and blue light, the colours in the final image only give an approximate representation of the actual colours of the galaxies in the image ; the choice of filters for the HDF ( and the majority of Hubble images ) was primarily designed to maximize the scientific utility of the observations rather than to create colours corresponding to what the human eye would actually perceive.

Because of difficulties in researching Iriomote cats in the wild, observations of Yon are currently the best example of the cats ' natural behavior.

Because light from hydrogen atoms in distant galaxies may reach the earth after having traveled across space for billions of years, in effect one can do such observations covering periods of time almost all the way back to the Big Bang, and they showed that the laws of physics had always been the same.

Because the many observations created a heavy workload, the payload

Because the galaxy has a high surface brightness and relatively large angular size, it is an ideal target for amateur astronomy observations.

Because the plot in Stravinsky's ballet chronicled the doomed antics of an animated puppet, it would have reflected his observations on the mechanical aspects of human behavior and appealed directly to the satirist in him.

Because cartographers usually made their observations far away from the mountainous remote areas and also because the Dent d ' Hérens is sometime hidden behind the Dent Blanche thus less visible, the latter received the name.

Because ones memory is affected by the associations, judgments, suggestions, penetrate into every one of our observations and taint out memory and our recollection of events.

Because it is so much easier to make observations of the contact patch without the tire in motion, it is more common to conduct studies of the static contact patch.

Because gamma rays and X-rays cannot penetrate Earth's atmosphere, direct observations must be made from space.

Because the costs and logistics of expanding Earth observations are daunting for any single nation, linking systems together through international cooperation also offers cost savings.

Because of lack of observations of the blue whale at that time, Melville asserts inaccurately that the sperm whale is the largest creature on Earth.

: Because many writers have uncritically repeated stereotypes shared by their sources, biases and prejudices have taken on the status of objective observations, including the idea that the Germans and British were the only belligerants in the Mediterranean after Italian setbacks in early 1941.

Because of its elliptical orbit, the spacecraft spent part of each day in the Van Allen belts, during which time science observations suffered from higher background noise.

Because the data are entered directly by participants into the Tucson Bird Count web site, results are publicly available on-line with little delay after observations are made.

Because Bright's speeches were so much a part of him, there are long and numerous quotations, which, far from making the biography diffuse, help to give us the feel of the man.

Because God is what He is, the laws of the universe, material and spiritual, are what they are.

Because, honey, I thought silently, there are plenty of desert islands in every marriage -- long periods when you're hopelessly stranded, together.

Because administration of the forest highway system is a responsibility of the Secretary of Commerce with maintenance provided by the States and counties, this Development Program for the National Forests does not include estimates of the funds needed to maintain the forest highway system nor to construct the additions to it that are needed.

Because they are `` minority '' exercises and have but a limited appeal they soon find themselves in the limbo of the forgotten.

Because of this, it would appear inevitable that an increasing percentage of strategic missiles will seek self-protection in mobility -- at least until missile defenses are perfected which have an exceedingly high kill probability.

( Note: Because of light leakage from one ultraviolet source to another, the lights are switched by a commutator-like assembly rotated by a synchronous motor.

Because of their location, on the edge of the feed lot, fence-line bunks are not in the way of mechanical manure removal.

Because agricultural activities are seasonal and the areas of production and harvest of many foods are widely scattered geographically, and because of the high cost of transporting bulk food items any substantial distance to a central processing location, the use of large central processing stations, where low-cost radiation facilities approaching the megawatt range might be utilized, is inherently impracticable.

Because electrical forces ( the charge-excess ) are far more powerful than gravitation, the surface hydrogen atoms would shoot away from the sphere.

Because the levels themselves are random variables, some assumptions and the method of contrasting the treatments ( a multi-variable generalization of simple differences ) differ from the fixed-effects model.

Because constitutional claims are of great magnitude, appellate courts might be more lenient to review the claim even if it was not preserved.

Because of the ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates.

Because of its simplicity, star hopping is a very common method for finding objects that are close to naked-eye stars.

Because CCD imagers are linear, image processing may be used to subtract away the effects of light pollution, which has increased the popularity of astrophotography in urban areas.

Because all clades are represented in the southern hemisphere but many not in the northern hemisphere, it is natural to conjecture that there is a common southern origin to them.

Because of their biological significance, amino acids are important in nutrition and are commonly used in nutritional supplements, fertilizers, and food technology.

Because of their relatively large mass, + 2 electric charge and relatively low velocity, alpha particles are very likely to interact with other atoms and lose their energy, so their forward motion is effectively stopped within a few centimeters of air.

Because of the tortuous terrain in places, villages and towns in the mountains — to which travel via motorized vehicles are of little use — are still located in the high Andes of Argentina, Bolivia, Peru, and Ecuador.

Because Ambrosius and Vortigern are shown in the Historia Brittonum as being in conflict, some historians have suspected that this preserves a historical core of the existence of two parties in opposition to one another, one headed by Ambrosius and the other by Vortigern.

Because of its elevation and distance from the coast, the Australian Capital Territory experiences four distinct seasons, unlike many other Australian cities whose climates are moderated by the sea.
