Before entering the dark room is to close my eyes for a few seconds, promised little adaptly to darkness. If this is not feasible, then at least to narrow the leading eye.It is clear that the human eye has a high development of the nervous parts, perfect optical system and various muscle devices that allow you to create the eyes and turn the adjustment optical device. This gives the person the ability to capture a wide range of visible light stimuli, the intensity of which may vary in 10 milliarder.Taking into account this, psychologists and physiologists different countries intensively studied Read more [...]
One of the principal characteristics in the spinning - this sensitivity. Sensitivity is dependent on the characteristics of all - build, test, ring material. This parameter must be prochuyat and feeling comes with experience. Tackle should be balanced. The overall sensitivity of the rod depends on the granularity of the material used. Higher module - those higher sensitivity spinning.
Each manufacturer of spinning uses in the manufacture of graphite grade forms, for example IM 8. The more graphite in the form, so it is more sensitive, and means that you can feel even the most cautious Read more [...]
Scientists predict global cooling by the end of the XXI century
on March 26. The forecast of continued climate warming is not justified, says the Chairman of the joint scientific Council of Earth Sciences RAS academician Nikolay Dobretsov.
According to him, evidenced by the changes in ice conditions in the Arctic.
«At least the ice was in 2007, in 2008-2011 and, apparently, in 2012, the ice began to grow again, you can see for yourself on a cold winters — in the Arctic cold again. So what we are waiting for a continuous warming — it is already obvious that this is Read more [...]
Would we climate in the period when the dinosaurs died out? Do we want to know what happens when the greenhouse gases pumped into the atmosphere at an unprecedented rate?As recent events have shown, even the World Bank would like to understand the trajectory of global warming. There are several ways, but most rely on indicators such as the climate sensitivity. The method of crude, but simple: a doubling of the atmospheric concentration of carbon dioxide average global temperature increases to a certain value.
The Intergovernmental Panel on Climate Change (IPCC) suggests that it is 2-4,5? C Read more [...]
Before entering into a dark room is to close your eyes for a few seconds, a small adaptptsiya guaranteed to darkness. If this is not possible, then at least screw up leading eye.
It is known that the human eye has a high development of the neural elements, perfect optical system and a variety of muscle device allowing the eye rotation and adjustment of their optical system. This gives a person the ability to capture a huge range of visible light stimuli, the intensity of which can vary 10 mlrd.raz.
With this in mind, psychologists and physiologists different countries actively investigated patterns Read more [...]
