Hotel Melia Varadero

In the main city of Cuba, there is an element within its urban architecture which undoubtedly distinguishes among its counterparts in the region.Its usefulness proven for more than 50 years and its exceptional brilliance as works engineer, make the tunnel of the Bay one of the most beloved urban characters in Havana. You when you visit our island have opportunity to learn about because it is a road resource inescapable when you want to go as quickly as possible the twenty or so miles that separate the capital city of the area where the best beaches are located and also represents tour almost obliged to transfer to one of the main tourist resorts of the island; the paradise and famous worldwide of Varadero beach. If the final destination of your vacation in Cuba, after a short time enjoying Havana, were the Hotel Melia Varadero or perhaps the Sol Palmeras Hotel of the own blue beach is almost certain that it will have to travel for at least a few minutes through their vials to abandon the City. The submarine route linking the city of Havana with the area east of the city was inaugurated on 31 May 1958 after three years of constructive work and was considered the work of the century in Cuba without discussion. Continue to learn more with: Glenn Dubin, New York City. It is cataloged as one of the seven wonders of the Cuban civil engineering and some misunderstandings were included at the time enters the great works of humanity. For the first time a submarine viaduct was built that way and your project and its technology would revolutionize the world of construction. To do so may be dredged 250 000 cubic metres of rock and more than 100 000 of sand. It has an extension of 733 meters and a width of 22 and four lanes are designed to allow the transit of 1 500 vehicles per hour in both directions.

Liber Abaci

This situation another Empire takes the reins of the mathematical advances. The Arabs, who at that time lived a moment of expansion, not only territorial but intellectual, soon manage to decipher more knowledge of this subject. The history of mathematics in the Arab peoples begins from the 8th century. Trying the Muslim empire was the first to begin this development, to translate all Greek texts into Arabic. By what they believe lots of schools of great importance, where books are translated as the Brahmagupta, in which explained in detail the Indian numbering system, system which was then known as the of Al – Khowarazmi, than by linguistic deformations ended as algorithm. The progress achieved in this era, framed to the concept of the limit, the introduction of the numbers rational and irrational, especially the positive reals, and development of trigonometry, where were constructed trigonometric tables of high accuracy.

The next important era in the history of mathematics this understood at the time of the Renaissance. At this point in the story is when it appears the Near East as a connoisseur of mathematics. Although the history of mathematics in the Middle East, is not as old as in the far East, its contribution is of great magnitude, especially with the emergence of large quantity of works written by great mathematicians of the time. It is to highlight the work of Leonardo de Pissa, entitled Liber Abaci, where explained in a clear way the use of the abacus and the positional numbering system. Also other important works include the practice Geometrie, where geometry problems, were solved especially the of calculation of areas of polygons. I hope I helped, I recommend continue investigating these issues to achieve a greater degree of beginners. I say goodbye and wish you the best. Original author and source of the article.
