Occasionally, you may come across one or two bumblebees in the cold season, when you are turning over sods in your garden, but you have to be a really keen observer to see them at all.

Another way to state this is that the emitting object may have a transverse velocity with respect to the observer, but any light beam emitted from it which reaches the observer, cannot, for it must have been previously emitted in such a direction that its transverse component has been " corrected " for.

The anthropic principle is often criticized for lacking falsifiability and therefore critics of the anthropic principle may point out that the anthropic principle is a non-scientific concept, even though the weak anthropic principle, " conditions that are observed in the universe must allow the observer to exist ", is " easy " to support in mathematics and philosophy, i. e. it is a tautology or truism

The Australian Outback is full of very well-adapted wildlife, although much of it may not be immediately visible to the casual observer.

In other cases the forces may be distributed among a large number of members, as in a truss, or not clearly discernible to a casual observer as in a box beam.

CRTs have also been used as memory devices, in which case the visible light emitted from the fluoresecent material ( if any ) is not intended to have significant meaning to a visual observer ( though the visible pattern on the tube face may cryptically represent the stored data ).

The total Doppler effect may therefore result from motion of the source, motion of the observer, or motion of the medium.

In studies of this type, the researcher may gather detailed field notes as a participant observer or passive observer.

In military applications black powder also produces thick smoke as a byproduct, which may give a soldier's location away to an enemy observer.

Kant distinguished things as they appear to an observer and things in themselves, " that is, things considered without regard to whether and how they may be given to us ".

There are exceptions within subjectivism however, such as ideal observer theory, which implies that moral facts may be known through a rational process, and individualist ethical subjectivism, which holds that moral facts are merely personal opinions and so may be known only through introspection.

A moral rationalist may adhere to any number of different semantic theories as well ; moral realism is compatible with rationalism, and the subjectivist ideal observer theory and noncognitivist universal prescriptivism both entail it.

In particular, a phenomenon that appears purely electric to one observer may be purely magnetic to another, or more generally the relative contributions of electricity and magnetism are dependent on the frame of reference.

* To the casual observer there may be no visual difference between veneers of natural and manufactured stone.

According to informal tradition, O stars are called " blue ", B " blue-white ", A stars " white ", F stars " yellow-white ", G stars " yellow ", K stars " orange ", and M stars " red ", even though the actual star colors perceived by an observer may deviate from these colors depending on visual conditions and individual stars observed.

* Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion.

Harsanyi claimed that his theory is indebted to Adam Smith, who equated the moral point of view with that of an impartial but sympathetic observer ; to Kant who insisted on the criterion of universality and which may also be described as a criterion of reciprocity ; to the classical utilitarians who made maximising social utility the basic criterion of morality ; and to ‘ the modern theory of rational behaviour under risk and uncertainty, usually described as Bayesian decision theory ’.

Radar may give a warning before there is any visual evidence of a tornado or imminent tornado, but ground truth from an observer can either verify the threat or determine that a tornado is not imminent.

One of the questions raised by the author concerns the objectivity of the sociologist: how may one study an object that, from the very beginning, conditions and relates to the observer?

The principal surviving literary sources are Dio Cassius ( a contemporary and sometimes first-hand observer, but for this reign, only transmitted in fragments and abbreviations ), Herodian and the Historia Augusta ( untrustworthy for its character as a work of literature rather than history, with elements of fiction embedded within its biographies ; in the case of Commodus, it may well be embroidering upon what the author found in reasonably good contemporary sources ).

Such a " Conversation for Action " can describe a situation in which an external observer ( such as a computer or health information system ) may be able to track the ILLOCUTIONARY ( or Speech Act ) STATUS of negotiations between the patient and physician participants even in the absence of any adequate model of the illness or proposed treatments.

Blacksmiths are credited with magical powers in many parts of the world, and it is significant that the Boudas are workers in iron and clay ; in the Life of N. Pearce ( i. 287 ) a European observer tells a story of a supposed transformation which took place in his presence and almost before his eyes ; but it does not appear how far hallucination rather than coincidence must be invoked to explain the experience.

This takes place over the western horizon in a brief period between sunset and moonset, and therefore the precise time and even the date of the appearance of the new moon by this definition will be influenced by the geographical location of the observer.

An observer sitting on the ( drifting ) perijove will see the moons coming into conjunction in the same place ( elongation ).

Despite the presence of an EU observer mission, canceled ballots and illegal voting took place, the majority of which in RPT strongholds.

However, this meeting took place after George W. Bush had become the President of the United States and had rejected the Kyoto Protocol in March 2001 ; as a result the United States delegation to this meeting declined to participate in the negotiations related to the Protocol and chose to take the role of observer at the meeting.

Typically, an observer from our world will journey to another place or time and see one society the author considers ideal, and another representing the worst possible outcome.

Although marked by magnificent festivities, at the time they took place the alliances were not seen as politically important, not even by the Imperial ambassador Jehan de Scheyfye, who was the most suspicious observer.

The severity of an omen is assessed based on its position with respect to the observer, its direction in respect to the observer, the time of its observation, the speed of the omen, the sounds heard during the omen, and the place where an omen is observed.

To calculate the visibility of a celestial object for an observer at a specific time and place on the Earth, the coordinates of the object are needed relative to a coordinate system of current date.

Suppose, for example, that one observer examines the properties of a hydrogen atom on Earth, the other — on the Moon ( or any other place in the universe ), the observer will find that their hydrogen atoms exhibit completely identical properties.

where Δt is the time interval between two co-local events ( i. e. happening at the same place ) for an observer in some inertial frame ( e. g. ticks on his clock ), this is known as the proper time, Δ < var > t '</ var > is the time interval between those same events, as measured by another observer, inertially moving with velocity v with respect to the former observer, v is the relative velocity between the observer and the moving clock, c is the speed of light, and

A less careful observer may think that they were not hereditary, but almost always their succession took place according to feudal rights of inheritance, utilizing the relatively high number of heiresses.

A transit of Earth across the Sun as seen from Mars takes place when the planet Earth passes directly between the Sun and Mars, obscuring a small part of the Sun's disc for an observer on Mars.
