An observation of a transit of Venus requires a huge range of auxiliary beliefs, such as those that describe the optics of telescopes, the mechanics of the telescope mount, and an understanding of celestial mechanics, all of which must be justified separately.

His principal nonphilosophical interest, arising from his observation of trolley cars beginning at an early age, is in what now is called light rail transit.

" In the 13th century, the Maragha astronomer Qotb al-Din Shirazi identified this observation as the transit of Venus and Mercury.

The first observation of a transit of Mercury was on November 7, 1631 by Pierre Gassendi.

That is, information is inevitably lost in transit from source to observation.

In 1873, he took a job with the Alvan Clark and Sons Company producing telescopes in Cambridge, Massachusetts, which then came under contract with the U. S. Navy to conduct observations of the transit of Venus on December 8, 1874, resulting in Tainter being sent with one of its observation expeditions to New Zealand.

The cost of growing mammalian cell cultures is high, so research is underway to produce such complex proteins in insect cells or in higher plants, use of single embryonic cell and somatic embryos as a source for direct gene transfer via particle bombardment, transit gene expression and confocal microscopy observation is one of its applications.

The Mohring effect is the observation that, if the frequency of a transit service ( e. g., buses per hour ) increases with demand, then a rise in demand shortens the waiting times of passengers at stops and stations.

The RATAN-600 is primarily operated as a transit telescope, in which the rotation of the earth is used to sweep the telescope focus across the subject of observation.

It was built on the suggestion of the astronomer Thomas Hornsby, who was occupying the Savilian Chair of Astronomy, following his observation of the notable transit of Venus across the sun's disc in 1769 from a room in the nearby Radcliffe Infirmary.

Another observation used in favor of the geocentric model at the time was the apparent consistency of Venus ' luminosity, which implies that it is usually about the same distance from Earth, which in turn is more consistent with geocentrism than heliocentrism.

* Venus Express — ESA probe sent for the observation of the Venus's weather ( 2005 )

After Galileo's observation of the phases of Venus in 1610, most cosmological controversy then settled on variations of the Tychonic and Copernican systems.

Lewis's description of Perelandra's environment and rotation period is, of course, inconsistent with the actual conditions on Venus, but astronomical observation at the time of writing of the novel had not yet positively determined this to be the case.

His deduction of the rotational period of Venus was based on the observation of its surface using a 2. 6 " ( 66mm ) 100 foot focal length aerial telescope.

The observation over such long periods of time has never been done in previous missions to Venus, and is key to a better understanding of the atmospheric dynamics.

* Owen Gingerich-Empirical proof and / or persuasion — lecture on Galileo's observation of the phases of Venus from a renowned historian of science

all is seen and felt and experienced, the observation is sharp and the imagination lively.

His own testimony is that he has read very little in the history of the South, implying that what he knows of that history has come to him orally and that he knows the world around him primarily from his own unassisted observation.

It is as if we, in our center of human observation, from time to time penetrate more deeply into the unknown.

What is exposited by this observation is not the inherent prejudices of Englishmen but the Anglophobia of Brooks Adams.

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

The best way to determine the correct figure ( in captives ) is by direct observation of pairs isolated from birth, a method that produced surprising results: maturing of a male Indian python in less than two years, his mate in less than three ; ;

The importance of knowing in what chemical forms the hormone may exist is accentuated by the recent observation that there exists an abnormally long-acting TSH in blood drawn from many thyrotoxic patients ( Adams, 1958 ).

Knowledge that thousands of school districts are involved and observation that school desegregation has occurred in only a handful in 1959-1960 leads to a conclusion that desegregation-from-court-order is slow.

This observation is of interest not only to students of Homeric poetry but to students of Anglo-Saxon poetry as well.

This explanation is attractive, but is vitiated at least in part by the observation that Cynewulf, though he used kennings in the traditional manner, was a literate man who four times inscribed his name by runes into his works.

It is a view which even a minimal effort at observation would immediately contradict.

First of all, and this has been calculated by observation, the universe is expanding -- that is, the galaxies are receding from each other at immense speeds.

Participant observation is one of the foundational methods of social and cultural anthropology.

A range of astronomy software is available and used by amateur astronomers, including software that generates maps of the sky, software to assist with astrophotography, observation scheduling software, and software to perform various calculations pertaining to astronomical phenomena.

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.

Two blocks west of the Old Town is the Kuchlbauer Brewery and beer garden featuring the Kuchlbauer Tower, a colorful and unconventional observation tower designed by Viennese architect Friedensreich Hundertwasser.

This has cooled it down to approximately 1 K, as deduced by astronomical observation, which is the lowest natural temperature ever recorded.

Perhaps Grothendieck's deepest single accomplishment is the invention of the étale and l-adic cohomology theories, which explain an observation of André Weil's that there is a deep connection between the topological characteristics of a variety and its diophantine ( number theoretic ) properties.

The aim of these exercises is to develop higher levels of consciousness through meditation and observation.

" The organ of observation and the observed thought process are then identical, so that the condition thus arrived at is simultaneously one of perception through thinking and one of thought through perception.
