In meteorology, virga is an observable streak or shaft of precipitation that falls from a cloud but evaporates or sublimes before reaching the ground. At high altitudes the precipitation falls mainly as ice crystals before melting and finally evaporating; this is often due to compressional heating, because the air pressure increases closer to the ground. It is very common in the desert and in temperate climates. In North America, it is commonly seen in the Western United States and the Canadian Prairies. It is also very common in Middle East and North Africa. Virga can cause varying weather effects, because as rain is changed from liquid to vapor form, it removes heat from the air due to the high heat of vaporization of water. In some instances, these pockets of colder air can descend rapidly, creating a dry microburst which can be extremely hazardous to aviation. Conversely, precipitation evaporating at high altitude can compressionally heat as it falls, and result in a gusty downburst which may substantially and rapidly warm the surface temperature. This fairly rare phenomenon, a heat burst, also tends to be of exceedingly dry air. Virga also has a role in seeding storm cells whereby small particles from one cloud are blown into neighboring supersaturated air and act as nucleation particles for the next thunderhead cloud to begin forming. Virga can produce dramatic and beautiful scenes, especially during a red sunset. The red light can be caught by the streamers of falling precipitation, and winds may push the bottom ends of the virga so it falls at an angle, making the clouds appear to have commas attached.
The spectacular Medici fountain in the Jardin du Luxembourg in Paris. Long ago in Sicily... Galatea was a sea nymph, a Nereid, who lived by the island inhabited by the Cyclops Polyphemus, son of Poseidon, who was deeply in love with Galatea. However Galatea liked the young shepherd Acis, son of Pan. Galatea and Acis used to mock Polyphemus's songs of love for Galatea. Polyphemus caught them sleeping on a grassy hill, and killed Acis by crushing him under a huge rock. Acis's blood formed a stream beneath the rock. Galatea turned it into a river and named it after him.The story of Acis and Galatea was told by Ovid in Book III of his Metamorphoses, and it is also the subject of a 1732 opera by Georg Friedrich Händel. - Frank da Cruz
Digital radiography is a form of X-ray imaging, where digital X-ray sensors are used instead of traditional photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also less radiation can be used to produce an image of similar contrast to conventional radiography.Instead of X-ray film, digital radiography uses a digital image capture device. This gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving for over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display of the image. - Wikipedia~
Agave americana, also called century plant, maguey or American aloe, is a species of flowering plant in the family Agavaceae, originally from Mexico but cultivated worldwide as an ornamental plant. It has since naturalised in many regions and grows wild in Europe, South Africa, India, and Australia. The misnamed century plant typically lives only 10 to 30 years. A monocarpic succulent, it has a spreading rosette (about 4 m (13 ft) wide) of gray-green leaves up to 2 m (6.6 ft) long, each with a spiny margin and a heavy spike at the tip that can pierce to the bone. When it flowers, the spike with a cyme of big yellow flowers may reach up to 8 m (26 ft) in height. Its common name likely derives from its semelparous nature of flowering only once at the end of its long life. The plant dies after flowering, but produces suckers or adventitious shoots from the base, which continue its growth.
I was in Paris, at the Opera Garnier, one of the most beautiful buildings in the entire world, lining up the perfect shot of that stunning facade. i was standing behind my tripod, cable release in hand. Just as I was about to trip the shutter, another photographer stepped into the frame to take a portrait of her friend. Realizing that the building was still going to be there a few minutes later, I instantly attempted to channel Henri Cartier-Bresson. This image is my homage to the great master.
Halfway through the Grand Canyon (north side of Colorado River), at Toroweap Valley, with Toroweap Lake (a playa lake), an outcrop, or point overlooks the West Grand Canyon section. It is the site of the Hurricane Fault-(of Hurricane Cliffs, of Arizona/Utah), the west fault, of the Uinkaret Mountains-(Mount Trumbull Wilderness). An eastern fault section separates here, and goes north into Utah, passing the west side of the Kanab Plateau.The Toroweap Overlook lies above the erosion resistant Tapeats Sandstone, near its west terminus in Grand Canyon. Southeast, across the river The Esplanade-(a regional section) is created, upon the erosion resistant Esplanade Sandstone, a resistant member of the Supai Group, (a unit above the Tapeats, but occurs on both the downside block, and upside block in the south side of the canyon, Colorado River); (The Esplanade is just upstream, with the Toroweap Fault forming its west flank). The Toroweap Overlook was visited in the 1800s by original photographers of the Grand Canyon.

Three Disarming Young Ladies These three stunning figures are part of a much larger group of statuary and architectural elements which were removed from the Parthenon in Athens, Greece, by Thomas Bruce, the seventh Earl of Elgin, the British Ambassador to the Ottoman Empire in the early nineteenth century. They now reside in the British Museum, in London.

The Roman Forum (Latin: Forum Romanum, Italian: Foro Romano) is a rectangular forum (plaza) surrounded by the ruins of several important ancient government buildings at the center of the city of Rome. Citizens of the ancient city referred to this space, originally a marketplace, as the Forum Magnum, or simply the Forum. It was for centuries the center of Roman public life: the site of triumphal processions and elections, venue for public speeches, criminal trials, and gladiatorial matches, and nucleus of commercial affairs. Here statues and monuments commemorated the city's great men. The teeming heart of ancient Rome, it has been called the most celebrated meeting place in the world, and in all history. Located in the small valley between the Palatine and Capitoline Hills, the Forum today is a sprawling ruin of architectural fragments and intermittent archeological excavations attracting numerous sightseers. Many of the oldest and most important structures of the ancient city were located on or near the Forum. The Roman kingdom's earliest shrines and temples were located on the southeastern edge. These included the ancient former royal residence, the Regia (8th century BC), and the Temple of Vesta (7th century BC), as well as the surrounding complex of the Vestal Virgins, all of which were rebuilt after the rise of imperial Rome.
