Ptolemy's problem is to forecast where, against the inverted bowl of night, some particular light will be found at future times.

The distances of these points of light is a problem he cannot master, beyond crude conjectures as to the orderings of the planetary orbits viewed outward from earth.

The discovery of CP violation helped to shed light on this problem by showing that this symmetry, originally thought to be perfect, was only approximate.

Their answers to the problem were similar, with the United States developing the M56 Scorpion and the Soviet Union developing the ASU-57, both essentially air-droppable light anti-tank guns.

Brooks stopped teaching recently to " devote 100 % of his time on solving the problem as to why he needed to eat some type of food to keep his physical body alive and allow his light body to manifest completely.

One can solve this problem by granting some degree of moral relativism and accepting that norms may evolve over time and, therefore, one can criticize the continued enforcement of old laws in the light of the current norms.

In the case of light shining through small circular holes we will have to take into account the full three dimensional nature of the problem.

Demonstrating that the light itself is quantized, not merely its interaction with matter, is a more subtle problem.

The significant recoil of the M14 when fired in full-automatic mode was seen as a problem as it reduced accuracy, and in the 1960s it was replaced by Eugene Stoner's AR-15, which also marked a switch from the powerful. 30 caliber cartridges used by the U. S. military up until early in the Vietnam War to the much less powerful but far lighter and light recoiling. 223 caliber ( 5. 56mm ) intermediate cartridge.

* Although the mean speed of the electron in hydrogen is only 1 / 137th of the speed of light, many modern experiments are sufficiently precise that a complete theoretical explanation requires a fully relativistic treatment of the problem.

A common light trespass problem occurs when a strong light enters the window of one's home from the outside, causing problems such as sleep deprivation or the blocking of an evening view.

The method for best reducing light pollution, therefore, depends on exactly what the problem is in any given instance.

To explain stellar aberration in the context of an aether-based theory of light was regarded as more problematic, because it requires that the aether be stationary even as the Earth moves through it — precisely the problem that led Newton to reject a wave model in the first place.

The latter theory was not considered as correct, since it was not compatible with the aberration of light, and the auxiliary hypotheses developed to explain this problem were not convincing.

Not only were there rival machines with " down-stroke " and " frontstroke " positions that gave a visible printing point, the problem of typebar clashes could be circumvented completely: examples include Thomas Edison's 1872 electric print-wheel device which later became the basis for Teletype machines ; Lucien Stephen Crandall's typewriter ( the second to come onto the American market ) whose type was arranged on a cylindrical sleeve ; the Hammond typewriter of 1887 which used a semi-circular " type-shuttle " of hardened rubber ( later light metal ); and the Blickensderfer typewriter of 1893 which used a type wheel.

An additional problem occurs when light must pass through a very narrow aperture to illuminate the scene ( consider a darkened room, with a door slightly ajar leading to a brightly lit room ), or a scene in which most points do not have direct line-of-sight to any light source ( such as with ceiling-directed light fixtures or torchieres ).

In our problem, we know,, ( e. g. the position of a light source ) and, and we need to find.

For theodicies of suffering, Weber argued that three different kinds of theodicy emerged-predestination, dualism, and karma-all of which attempt to satisfy the human need for meaning, and he believed that the quest for meaning, when considered in light of suffering, becomes the problem of suffering.

The problem can be understood in terms of the relativity of simultaneity in special relativity, which says that different inertial reference frames will disagree on whether two events at different locations happened " at the same time " or not, and they can also disagree on the order of the two events ( technically, these disagreements occur when spacetime interval between the events is ' space-like ', meaning that neither event lies in the future light cone of the other ).

In his book Rude Kids: The Inside Story of Viz, the comic's creator Chris Donald claimed that the first legal action ever taken against Viz was initiated by a man who objected to the use of a picture of his house ( taken from an estate agent's catalogue ) in one of these photo-strips, and that the British tabloid newspaper Sunday Mirror tried to provoke media outrage over another photo-strip which, if taken out of context, could be misconstrued as making light of the problem of illegal drugs being offered to children.

But a problem quickly arose when determining the vibrational modes of light.

A laser could be used as a photon rocket engine, and would solve the reflection / collimation problem, but lasers are absolutely less efficient at converting energy into light than blackbody radiation is — though one should also note the benefits of lasers vs blackbody source, including unidirectional controllable beam and the mass and durability of the radiation source.

The problem in the policy officer's mind thus begins to take shape as a galaxy of utterly complicated factors -- political, military, economic, financial, legal, legislative, procedural, administrative -- to be sorted out and handled within a political system which moves by consent in relation to an external environment which cannot be under control.

The problem arises, if it does arise, when the educator has to make a choice or a decision within the area of his professional competence, but which bears some relation to the social structure.

Thus, the Commission acted with a sense of social responsibility within the area of its own convictions about the problem of government support to private education.

But Parker as the ultra-liberal minister within the pale of a church which had proclaimed itself the repository of liberality poses a different problem, which is not to be resolved by holding him up as the champion of freedom.

In summary, while we stress that constructive engagement between anthropology and the military is possible, CEAUSSIC suggests that the AAA emphasize the incompatibility of HTS with disciplinary ethics and practice for job seekers and that it further recognize the problem of allowing HTS to define the meaning of “ anthropology ” within DoD.

It would appear that the subsidizing of southern populations by the import of wheat from the north of the Empire temporarily overcame this problem, and it seems to have allowed economic recovery and a growing population within this region.

Note that the continuous crossover between the dilute and dense regimes of attracting pairs of fermions is still an open problem, which now attracts a lot of attention within the field of ultracold gases.

Another problem is seen in the lower average wages and family incomes within the region.

The extinction of the Dodo within only about a century of its discovery called attention to the previously unrecognised problem of human involvement in the disappearance of entire species.

For example, the problem of trisecting an angle with a compass and straightedge is one that naturally occurs within the theory, since the axioms refer to constructive operations that can be carried out with those tools.

The problem becomes even more severe on a cyclical basis when sunspot levels reach a maximum every 11 years and lower VHF band signals below 50 MHz can travel across the Atlantic Ocean or from coast to coast within North America on occasion.

In general, divisions within the church at Corinth seem to be a problem, and Paul makes it a point to mention these conflicts in the beginning.

The CCD sensor was shielded from radiation, a particular problem within the harsh Jovian magnetosphere.

In response to this problem, some LED lighting systems have been designed with an added heating circuit at the expense of reduced overall electrical efficiency of the system ; additionally, research has been done to develop heat sink technologies that will transfer heat produced within the junction to appropriate areas of the luminaire.

In 1941, the problem of frequency instability was solved by coupling (" strapping ") alternate cavities within the magnetron.

The authors claimed that within three or five years, machine translation would be a solved problem.

A major problem is gaining long-term adherence to therapy from people with osteoporosis with half not taking their medications and most discontinuing within one year.

Most household goods are exempt as long as they are kept or used within the household ; the tax usually becomes a problem when the taxing authority discovers that expensive personal property like art is being regularly stored outside of the household.

Cavalieri first used polar coordinates to solve a problem relating to the area within an Archimedean spiral.

Modern day clergy and practitioners within some religious movements have no problem classifying the religion's sacred stories as " myths ".

It has been proposed that the first problem could be resolved by making Easter occur on a fixed date every year, or alternatively on a Sunday within a fixed range of seven dates.

With disunity within the realm no longer a problem, the new king of England, Henry II, soon turned his attention to Wales.

* Examining the possibility of reducing the number of variables being considered within a problem ( the task of Dimension reduction )

Jerrum, Valiant, and Vazirani showed that every # P-complete problem either has an FPRAS, or is essentially impossible to approximate ; if there is any polynomial-time algorithm which consistently produces an approximation of a # P-complete problem which is within a polynomial ratio in the size of the input of the exact answer, then that algorithm can be used to construct an FPRAS.
