:" The man, an admirable magistrate, with an aristocratic comportment and a romantic look, who once was one of the most handsome boys of his time, had transformed himself, in half-a-dozen months, into an old, curved and pathetic man ...

This church was chosen for several reasons: ( 1 ) Like other baths in Rome, the building was already naturally southerly oriented, so as to receive unobstructed exposure to the sun ; ( 2 ) the height of the walls allowed for a long line to measure the sun's progress through the year more precisely ; ( 3 ) the ancient walls had long since stopped settling into the ground, ensuring that carefully calibrated observational instruments set in them would not move out of place ; and ( 4 ) because it was set in the former baths of Diocletian, it would symbolically represent a victory of the Christian calendar over the earlier pagan calendar.

" Its changes in colour would allow determining the sun's position ( azimuth ) even through an overcast or foggy horizon.

The majority of mission sanctuaries were oriented on a roughly east-west axis to take the best advantage of the sun's position for interior illumination ; the exact alignment depended on the geographic features of the particular site.

On the back of the mater there is often engraved a number of scales that are useful in the astrolabe's various applications ; these vary from designer to designer, but might include curves for time conversions, a calendar for converting the day of the month to the sun's position on the ecliptic, trigonometric scales, and a graduation of 360 degrees around the back edge.

When used this way, a navigator will from time to time measure the sun's altitude with a sextant, then compare that with a precalculated altitude based on the exact time and estimated position of the observation.

Flowers open in response to light intensity ( often opening only in direct sunlight ), and the entire inflorescence is also helitropic, moving in response to the sun's position in the sky.

However, when the chapel was connected to the main hall a further 60 years later, the angle of connection was less than 90 ° because of the solstice change in the sun's position over the years.

Knowing these will enable the observer to be more precise when determining the cardinal directions from the sun's position, particularly in the early morning or late afternoon.

The moment of the sun's closest approach to the horizon coincides with its passing due north at the observer's position, which occurs only approximately at midnight in general.

Attenborough visits the Sahara to illustrate a species that makes the longest overland journey of any insect: cataglyphis, an ant that uses the sun's position to enable it to return to its nest in a straight line.

Roughly every 2, 150 years the sun's position at the time of the vernal equinox will have moved into a new zodiacal constellation.

The sun's position is taken as the ascendant of the chart and equal sized houses of 30 degrees each are used ; or alternatively, the sunrise chart can be used, with the sun's position at sunrise at the latitude in question taken as the ascendant.

The term Mezzogiorno first came into use in the 18th century and is an Italian rendition of meridies ( Latin for ' south ', because of the sun's position at midday in the Northern Hemisphere ).

The majority of structures, indeed whole villages, were oriented on a roughly east-west axis to take the best advantage of the sun's position for interior illumination ; the exact alignment depended on the geographic features of the particular site.

The majority of mission sanctuaries were oriented on a roughly east – west axis to take the best advantage of the sun's position for interior illumination ; the exact alignment depended on the geographic features of the particular site.

A new dynamic shadow system was added to move the location of a shadow which was dependent on the sun's position for weather changes.

Because individuals with albinism have skin that entirely lacks the dark pigment melanin, which helps protect the skin from the sun's ultraviolet radiation, their skin can burn more easily from overexposure.

The flow is powered by the million-degree temperature of the sun's corona, for which no generally accepted explanation exists yet.

The sun's rays enters into the atmosphere of Nigeria more intense than it does during the presence of the Tropical continental airmass, which contained dust ( in form of haze ) that reduced the intensity of the sun.

The glass roof extends down to the ground which give the conservatory a distinctive appearance and helps to maximise the use of the sun's energy.

Bernal wrote in 1929, " A form of space sailing might be developed which used the repulsive effect of the sun's rays instead of wind.

The reason for this temperature difference is the absorption of the sun's energy occurs at the ground which heats the lower levels of the atmosphere, and the radiation of heat occurs at the top of the atmosphere cooling the earth, this process maintaining the overall heat balance of the earth.

The valley is surrounded by mountains, while its surface is mostly flat and devoid of plants, and of which a high percentage of the sun's heat is able to reach the ground, absorbed by soil and rock.

Microclimates exist, for example, near bodies of water which may cool the local atmosphere, or in heavily urban areas where brick, concrete, and asphalt absorb the sun's energy, heat up, and reradiate that heat to the ambient air: the resulting urban heat island is a kind of microclimate.

The English noun Sunday derived sometime before 1250 from sunedai, which itself developed from Old English ( before 700 ) Sunnandæg ( literally meaning " sun's day "), which is cognate to other Germanic languages, including Old Frisian sunnandei, Old Saxon sunnundag, Middle Dutch sonnendach ( modern Dutch zondag ), Old High German sunnun tag ( modern German Sonntag ), and Old Norse sunnudagr ( Danish and Norwegian søndag, Icelandic sunnudagur and Swedish söndag ).
