Much of what we believe the product of modern science, was known to mankind even in ancient times, but subsequently, for whatever reasons, forgotten. Moreover, as the science of the different human cultures developed very different way than ours, in the surviving monuments can be hidden knowledge, not yet known to us.
Today we know that the pharaohs were put in pyramids science, origin and methods which we do not know. We find there the number “PI”, the exact calculation of the duration of the solar year, the radius and the weight of Earth, distance from the earth to the Sun, astronomical law of the precession of the equinoxes, the magnitude of the degree of longitude, the actual direction to the North and probably many other, not yet deciphered data.
The debate is about tenths, however, the building of pyramids shows the technique that remain completely incomprehensible to us. This is an artificial mountain weighs 6.5 million tons. Blocks up to 12 tons weight of each fitting to each other with polumillimetrovy accuracy. Most often there the most flat idea: Pharaoh had an enormous number of slaves. It remains to explain the manner in which was solved the problem of placement of these huge crowds? Continue reading
The concept of “ancient art” first appeared in the XV century in Italy, when in combat with thousands of years of Church tradition of the middle ages argued new, is permeated with faith in the beauty and value of human culture of the Renaissance.
Its creators turned to the wonderful creations of Ancient Greece and Ancient Rome. This great civilization of the ancient world they called the ancient (from the Latin word “antiquus” – “ancient”). Subsequently, the term “antique art” firmly entrenched in European culture.
Masterpieces, created by talented masters of the ancient world, for several centuries inspired poets, composers, playwrights and artists all over Europe, and today continues to give us artistic pleasure and to serve as a norm and unattainable model.
Artistic heritage of Ancient Greece and Ancient Rome – architecture, sculpture, painting, decorative-applied and jeweller art is striking in its richness and diversity. In it a clearly expressed aesthetic views, moral ideals and tastes, typical of the ancient civilization that ended the long history of the ancient world. The creators of ancient culture were the ancient Greeks called themselves Hellenes and their country Hellas. Continue reading
Construction of underground metro stations is one of the technically challenging and labour-intensive industries of modern construction with relatively high material and financial costs.
The volume and scope of work at the station is determined by the type and number of facilities included in the station complex. These facilities are designed for boarding, disembarking and transfer of passengers (station tunnels and distribution facilities, escalator tunnels with suspended cameras engine room, underground and surface halls, connective and transitional passages), the organization of movement of trains (traction-secondary substation, circulating devices and stubs) and for compliance with appropriate sanitary-hygienic conditions (ventilation shafts, tunnels, chambers and kiosks, toilets and drainage pumping chambers).
In addition to constructing tunnels and chambers for different purposes, at stations is a large amount of construction, installation and finishing works. These include the construction of the in-tunnel structures (passenger platforms, trackside devices, catwalks, stairs, office space, cable channels, foundations under escalators, etc.), installation of waterproof umbrellas and architectural design of passenger buildings, installation of escalators equipment, traction-secondary substation, ventilation and drainage installations,sanitary units, lighting.
