The book “the Age of man. The world we created”

Hello! We got a wonderful new Diane Ackerman:


image People “have mastered 75% of the land surface has created a lot of truly marvelous industrial and medical inventions, he has covered the entire planet”. Nature is not a temple but a workshop, we populated the biosphere of our favorite species of plants and animals, many of which are invasive; we even altered the climate, threatening our own existence. However, we are aware of their own destructive tendencies and can boast of stunning creative achievements. We collect the DNA of vanishing species in a “frozen ark”, teaching orangutans to go with iPads, creating a high-tech wearable devices and even artificial species that may someday surpass us. The author Diane Ackerman, has a rare gift available to explain advanced science readers-professionals, arranges an amazing tour through the surrounding new reality introduces to a lot of people that determine the development of modern science, with ideas that in our eyes determine the vector of development of civilization, and perhaps save her.

About the leftist movements and the future


The experience of left movements in Latin America tells us that without serious consideration of the psychological and economic issues the social revolution in the modern world impossible. Dreams and theories (Marxist, or national liberation) is not enough. Attempts social preobrazovania society rests in the reproduction of the human type, who need the conversion, which is ready to fight for it and to protect and develop. This appears to be a common feature of collapsed or passed to the defense of left-wing projects from the Soviet Union to Venezuela.

Rolled metal

Rolling:


Before rolling of iron applied to the rolling of nonferrous metals — lead, tin, copper, coinage, alloys, etc. the earliest document (picture with description) that characterize the device for rolling of tin left by Leonardo da Vinci (1495). Until about the late 17th century, the actuator of the rolling mill was manual, in the 18th century water. The industrial rolling of iron began in the 18th century, Rolling mills were used to produce roofing iron, flattening ladle blanks in strip or sheet, of division forged bands lengthwise into smaller profiles of square or rectangular cross section.
At the end of the 18th century to drive the rolling mills began to use steam engines; rolling becomes one of the three main parts of the production cycle of metallurgical plants, gradually displacing less efficient method of forging. To this period belongs the industrial rolling mill with grooved rolls, constructed in 1783 by the Court Velikobritaniya); rolling mills gradually differenciate to crimping, sheet and varietal. In 30-40-ies of the 19th century in connection with rapid development of Railways in different countries start laminating the rails. In 1856-57 in Saarland (Germany) installed the first mill for rolling large beams. In 1867, Bedson (UK) built a continuous wire mill. In 1885 the brothers M. and R. Mannesmann (Germany) invented a method of rolling seamless pipe in rolling mill with obliquely arranged rollers. In 1886 edenborn V., and C. Morgan (USA) used high-speed wire coiler with axial feed. First, the shear (design B. Edwards) established in 1892 in the United States. In 1897 to drive rolling mills successfully applied motor (Germany). In 1906 in the city of Trinec started up a rolling mill with a reversible motor. The principle of continuous hot rolling of sheets found practical application in 1892 in the town of Teplice, where he was set to semi-continuous mill. Shirokopolosnoi the first continuous sheet mill was built in 1923 in the United States. Beginning of cold rolling sheets applies to the 80-th years of the 19 century; cold rolling of tubes developed in the 1930s in the United States.

IBM and Samsung have developed 11-nm STTMRAM memory

This month, IBM celebrated the 20th anniversary of the development of magnetoresistive random access memory with random access (MRAM). Initially, the goal was set in the control cell by means of an electromagnetic field. The project is now transformed into the development of memory cells recording information by using the transfer torque of the spin electron. This type of memory has received the name of STTMRAM (spin-transfertorqueMRAM).
