Brebeneskul (, ) is a peak in the Chornohora region of Ukraine, with height of 2,035 meters above sea level. The second highest peak of Ukraine.
Solar energy
Solar concentrating technologies such as parabolic dish, trough and Scheffler reflectors can provide process heat for commercial and industrial applications. The first commercial system was the Solar Total Energy Project (STEP) in Shenandoah, Georgia, USA where a field of 114 parabolic dishes provided 50% of the process heating, air conditioning and electrical requirements for a clothing factory. This grid-connected cogeneration system provided 400 kW of electricity plus thermal energy in the form of 401 kW steam and 468 kW chilled water, and had a one-hour peak load thermal storage. Evaporation ponds are shallow pools that concentrate dissolved solids through evaporation. The use of evaporation ponds to obtain salt from sea water is one of the oldest applications of solar energy. Modern uses include concentrating brine solutions used in leach mining and removing dissolved solids from waste streams. Clothes lines, clotheshorses, and clothes racks dry clothes through evaporation by wind and sunlight without consuming electricity or gas. In some states of the United States legislation protects the "right to dry" clothes. Unglazed transpired collectors (UTC) are perforated sun-facing walls used for preheating ventilation air. UTCs can raise the incoming air temperature up to 22 °C (40 °F) and deliver outlet temperatures of 45–60 °C (113–140 °F). The short payback period of transpired collectors (3 to 12 years) makes them a more cost-effective alternative than glazed collection systems. As of 2003, over 80 systems with a combined collector area of 35,000 square metres (380,000 sq ft) had been installed worldwide, including an 860 m2 (9,300 sq ft) collector in Costa Rica used for drying coffee beans and a 1,300 m2 (14,000 sq ft) collector in Coimbatore, India, used for drying marigolds.
Western Wall
The Western Wall is considered holy due to its connection to the Temple Mount. Because of the Temple Mount entry restrictions, the Wall is the holiest place where Jews are permitted to pray, though the holiest site in the Jewish faith lies behind it. The original, natural, and irregular - shaped Temple Mount was gradually extended to allow for an ever - larger Temple compound to be built at its top. This process was finalised by Herod, who enclosed the Mount with an almost rectangular set of retaining walls, built to support extensive substructures and earth fills needed to give the natural hill a geometrically regular shape. On top of this box - like structure Herod built a vast paved esplanade which surrounded the Temple. Of the four retaining walls, the western one is considered to be closest to the former Temple, which makes it the most sacred site recognised by Judaism outside the former Temple Mount esplanade. Just over half the wall's total height, including its 17 courses located below street level, dates from the end of the Second Temple period, and is commonly believed to have been built around 19 BCE by Herod the Great, although recent excavations indicate that the work was not finished by the time Herod died in 4 BCE. The very large stone blocks of the lower courses are Herodian, the courses of medium - sized stones above them were added during the Umayyad era, while the small stones of the uppermost courses are of more recent date, especially from the Ottoman period.
Great Wall of China
One of the most striking sections of the Ming Great Wall is where it climbs extremely steep slopes in Jinshanling. There it runs 11 km (7 mi) long, ranges from 5 to 8 m (16 ft 5 in to 26 ft 3 in) in height, and 6 m (19 ft 8 in) across the bottom, narrowing up to 5 m (16 ft 5 in) across the top. Wangjinglou (t 望京樓, s 望京楼, Wàngjīng Lóu) is one of Jinshanling's 67 watchtowers, 980 m (3,220 ft) above sea level. Southeast of Jinshanling is the Mutianyu Great Wall which winds along lofty, cragged mountains from the southeast to the northwest for 2.25 km (1.40 mi). It is connected with Juyongguan Pass to the west and Gubeikou to the east. This section was one of the first to be renovated following the turmoil of the Cultural Revolution.
Han dynasty
Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds.
Bessemer process
A system akin to the Bessemer process has existed since the 11th century in East Asia. Economic historian Robert Hartwell writes that the Chinese of the Song Dynasty innovated a ``partial decarbonization ''method of repeated forging of cast iron under a cold blast. Sinologist Joseph Needham and historian of metallurgy Theodore A. Wertime have described the method as a predecessor to the Bessemer process of making steel. This process was first described by the prolific scholar and polymath government official Shen Kuo (1031 -- 1095) in 1075, when he visited Cizhou. Hartwell states that perhaps the earliest center where this was practiced was the great iron - production district along the Henan -- Hebei border during the 11th century.
Celluloid
The first celluloid as a bulk material for forming objects was made in 1855 in Birmingham, England, by Alexander Parkes, who was never able to see his invention reach full fruition, after his firm went bankrupt due to scale - up costs. Parkes patented his discovery after realising a solid residue remained after evaporation of the solvent from photographic collodion.
Modern history
Worldwide prosperity changed dramatically with the onset of the Great Depression in 1929. The Wall Street Crash of 1929 served to punctuate the end of the previous era, as The Great Depression set in. The Great Depression was a worldwide economic downturn starting in most places in 1929 and ending at different times in the 1930s or early 1940s for different countries. It was the largest and most important economic depression in the 20th century, and is used in the 21st century as an example of how far the world's economy can fall.
Lath and plaster
Lath and plaster is a building process used to finish mainly interior walls and ceilings in Canada and the United States until the late 1950s. After the 1950s, drywall began to replace the lath and plaster process in the United States.
Wang Chong
Wang Chong (; 27 – c. 100 AD), courtesy name Zhongren (仲任), was a Chinese meteorologist, astronomer, and philosopher active during the Han Dynasty. He developed a rational, secular, naturalistic and mechanistic account of the world and of human beings and gave a materialistic explanation of the origin of the universe. His main work was the "Lunheng" (論衡, "Critical Essays"). This book contained many theories involving early sciences of astronomy and meteorology, and Wang Chong was even the first in Chinese history to mention the use of the square-pallet chain pump, which became common in irrigation and public works in China thereafter. Wang also accurately described the process of the water cycle.
Mount Whillans

Crystal Island
Crystal Island is a future building project in Moscow, Russia that is planned to have around 2,500,000 square meters (27,000,000 square ft) of floor space and a height of 450 meters (1,476 ft) designed by Norman Foster. At these dimensions upon completion it would be the largest structure (in floor space) on earth. The architectural firm behind the design is Foster and Partners.
Great Wall of China
The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east - to - west line across the historical northern borders of China to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe. Several walls were being built as early as the 7th century BC; these, later joined together and made bigger and stronger, are collectively referred to as the Great Wall. Especially famous is the wall built in 220 -- 206 BC by Qin Shi Huang, the first Emperor of China. Little of that wall remains. The Great Wall has been rebuilt, maintained, and enhanced over various dynasties; the majority of the existing wall is from the Ming Dynasty (1368 -- 1644).
Pretoria (ship)
Pretoria, an American schooner barge, was one of the largest wooden ships ever constructed. She was 103 meters (338 ft) long, had a beam of 13.4 meters (44 ft), and 7 meters (23 ft) in depth. She was built by James Davidson in West Bay City, Michigan, for use on the Great Lakes.
Walls of Jerusalem
The Walls of Jerusalem (Hebrew: חומות ירושלים) surround the Old City of Jerusalem (approx. 1 km²). In 1535, when Jerusalem was part of the Ottoman Empire, Sultan Suleiman I ordered the ruined city walls to be rebuilt. The work took some four years, between 1537 and 1541.The length of the walls is 4,018 meters (2.4966 mi), their average height is 12 meters (39.37 feet) and the average thickness is 2.5 meters (8.2 feet). The walls contain 34 watchtowers and seven main gates open for traffic, with two minor gates reopened by archaeologists.
Arenal Volcano
The eruptions of May 7, 1998 damaged two square kilometers and destroyed a 400 by 100 meter area of green forest in the vicinity of Arenal Volcano. A fissure, 500 meters long and 10 meters deep, was opened up in the wall of the crater and all the material slid down the side of the volcano.
Cerro Fábrega
Cerro Fábrega is a mountain in Bocas del Toro Province of western Panama. It has a height of 3,335 meters (10,942 feet).
John Augustus Just
Dr. John Augustus Just (January 9, 1854 – September 13, 1908) was a German-born chemist and inventor. He is best known for his investigative work into recovery of precious metals from their ores and for completing the process for evaporating milk. For his scientific achievements, he was awarded a medal by the committee celebrating Berthelot's 50th anniversary.
