Un des défis de l'agronomie est de mieux comprendre les variations inter et intra-parcellaires (ici mises en évidence par l'image satellitale fausses-couleurs) pour mieux adapter la gestion du sol et des plantes aux conditions pédogéologiques et contextuelles locales, ainsi qu'à leurs évolutions temporelles (photo : NASA Earth Observatory)[2]
English: These three false-color images demonstrate some of the applications of remote sensing in precision farming. The goal of precision farming is to improve farmers’ profits and harvest yields while reducing the negative impacts of farming on the environment that come from over-application of chemicals. The images were acquired by the Daedalus sensor aboard a NASA aircraft flying over the Maricopa Agricultural Center in Arizona. The top image (vegetation density) shows the color variations determined by crop density (also referred to as "Normalized Difference Vegetation Index", or NDVI), where dark blues and greens indicate lush vegetation and reds show areas of bare soil. The middle image (water deficit) is a map of water deficit, derived from the Daedalus’ reflectance and temperature measurements. Greens and blues indicate wet soil and reds are dry soil. The bottom image (crop stress) shows where crops are under serious stress, as is particularly the case in Fields 120 and 119 (indicated by red and yellow pixels). These fields were due to be irrigated the following day. See also Precision Farming (Feature Article on earthobservatory.nasa.gov).

This fused quartz sphere was manufactured for use in a gyroscope in the Gravity Probe B experiment. It is one of the most accurate spheres ever manufactured, deviating from a perfect sphere by no more than 40 atoms of thick­ness. Only neutron stars and the single-crystal silicon spheres used in the Avogadro Project are thought to be smoother.

Старая дева

Английская карикатура XVIII века.

The lady here you see display’d,

By some is styled an ancient maid,

But if her inward thoughts you’d view,

She thinks herself as young as you.

Леди, что видишь перед собой,

Старой девой назвал бы иной.

Сама же она сочтёт себя

Ничуть не старше тебя.

Ashton Court displays a profusion of architectural styles. Here various wings and juxtapositions display Strawberry Hill Gothic to the left, Italian Renaissance windows to the right, a Victorian Porte cochere in the centre, simple Tudor mullion and Gothic tracery windows, plus pseudo-medieval battlements and chaste English renaissance gables.
English: Ashton Court Mansion in Ashton Court Estate Ashton Court Estate was acquired by Bristol City Council in 1959, but the place has a long history. There is clear evidence of the ridged strips of Saxon fields, but with the coming of William the Conqueror the area was transferred into Norman ownership. In 1392 Thomas de Lyons was granted a licence to enclose his lands and make a park, the foundation of the modern one. During the 16th century Ashton Court was bought by John Smyth, a merchant from Small Street. He and his descendants gradually enlarged, rebuilt, remodelled and reconstructed various parts of the house. In 1939 it was requisitioned by the War Office, used in turn as a Transit Camp, RAF HQ and American Army Command HQ. The last Smyth owner died in 1946 and for 13 years the house, already in disrepair, lay empty. When the City Council bought the Estate much expensive work had to be carried out. Gradually considerable conservation and restoration has been achieved and is still continuing.

Goethe juge Beethoven : « Je n’ai encore jamais vu un artiste plus puissamment concentré, plus énergique, plus intérieur. (…) C’est malheureusement une personnalité tout à fait indomptée[2] ». Beethoven espérait beaucoup de sa rencontre en 1812 avec le poète, mais il n’y trouva qu’une indifférence calculée.

Alfred Jacob Miller - Sioux Indians in the Mountains - Miller en route to a Rocky Mountain Rendezvous In the spring of 1837, Captain William Drummond Stewart hired the Baltimorean Alfred Jacob Miller to accompany and record an expedition to the annual fur traders' rendezvous held in the foothills of the Rocky Mountains in what is now Wyoming.
English: In the spring of 1837, Captain William Drummond Stewart hired the Baltimorean Alfred Jacob Miller to accompany and record an expedition to the annual fur traders' rendezvous held in the foothills of the Rocky Mountains in what is now Wyoming. That autumn, the artist returned east with sketches and watercolors, which served as the basis for later paintings. Miller observed that Americans could find in their own country "a race of men equal in form and grace (if not superior) to the finest ideal ever dreamed of by the Greeks." With the financial assistance of Baltimore collector Robert Gilmor, Jr., Miller studied in Europe in 1832-33, where he was attracted to the works of the Romantic artists, particularly Decamps and Delacroix, as well as to paintings he saw in the Louvre Museum by Dutch 17th-century masters.

A fully deployed solar sail system at the NASA Glenn Research Center's Plum Brook Space Power Facility, the world's largest space environment simulation chamber, in Sandusky. The development of these sails has been critical for future robotic space exploration and the chamber will be featured in the upcoming motion picture "The Avengers".[58]
English: A 20-meter solar sail and boom system, developed by ATK Space Systems of Goleta, Calif., is fully deployed during testing at NASA Glenn Research Center's Plum Brook facility in Sandusky, Ohio. Blue lights positioned beneath the system help illuminate the four triangular sail quadrants as they lie outstretched in Plum Brook's Space Power Facility -- the world's largest space environment simulation chamber. The sail material is supported by a series of coilable booms, which are extended via remote control from a central stowage container about the size of a suitcase, and is made of an aluminized, plastic-membrane material called CP-1. The material is produced under license by SRS Technologies of Huntsville, Ala. The deployment, part of a series of tests in April, is a critical milestone in the development of solar sail propulsion technology that could lead to more ambitious inner Solar System robotic exploration.
