Interesting facts about construction — part 1
Who built the pyramids
Disputes over the authors of the pyramids continue to this day. Many versions from the official to the extraterrestrial excite the minds of researchers. Despite this, today it is possible with a high degree of probability to assume with whose hands the construction of the pyramids was carried out. Egyptologists rarely change their established point of view. But the version based on the works of Herodotus that slave labor was used during the construction has already been revised. At the moment, it is believed that the pyramids were built by the main population of the country, which was a kind of labor service. Not far from Giza, a necropolis was found with, as is expected, the tombs of architects, foremen and rather poor burials of ordinary workers. Also, a large complex for the production of food for feeding workers has been excavated. The nature of the buildings and the remains and other finds allow scientists to argue that slaves were not used in the construction of the pyramids.
A country where you shouldn't invest in real estate
In most countries, buying a property is a great investment. Its value is steadily growing, allowing not only to preserve, but also to increase its capital. However, in Japan, things are completely different. From the very first day of construction, Japanese buildings begin to fall in value, lose half their value in the first 10 years, and almost completely depreciate in 25 years. Here the house is a consumer product, not an investment. This is due to the following features. Urgent mass construction after the end of World War II left behind a large number of houses of extremely poor quality, which formed a negative perception of old buildings among the population. In addition, ever-changing seismic safety regulations, new technologies and materials are leading buyers to choose new, safer homes. This feature is a continuation of the long-formed Japanese mentality of fleetingness - any building can be destroyed by the elements in a matter of seconds. Even the most important shrines in Japan are regularly updated and rebuilt. An additional factor is that it is much easier to get a bank loan to build a new home than to buy an old one.
Why is the Pentagon so shaped
Oddly enough, but in the pentagonal form there is no mysticism, sacred meaning or symbolism. Everything is pretty prosaic and utilitarian. Initially, a site in the suburbs of Washington, which had the shape of an irregular pentagon, was chosen as the site for the construction. It was assumed that the building would be adjacent to the intersection of roads, the intersection angle of which was 108 degrees, which exactly corresponds to the angle of the pentagon. The architects tried to harmoniously fit the office complex into the existing structure of the district, laying a regular pentagon in the base of the building. But after a while, President Roosevelt ordered to move the building almost a kilometer so that it did not block the view of the city from Arlington Cemetery. And, since the project was already in development, it was decided to move the construction site, leaving the appearance of the headquarters of the US Department of Defense unchanged.
