70% of users do not think yourself without the Internet. This, according to HAKER.ru show results of an international consulting and auditing company Synovate.
In the survey on market media and advertising, 8600 respondents participated from around the world.
Physicists have found that drops of liquid is subject to customary laws of friction. Article scientists appeared in the journal Physical Review Letters, and its brief cites Physical Review Focus.
Traditionally, friction is proportional normal component of reaction force support. In fact, this means that, for example, heavy box to pull on the surface harder than light. As it turned out, if the liquid comes to a totally different situation.
In the study researchers also include a few drops of oil volume mikrolitramy a special mechanical arm that revolved around some axis. Thus scientists can change the angle of arm and speed (which allowed researchers to control the different forces acting on the drop).
Behavior of liquid znimalasya located next to the camera.
Scientific managed to show that the icecap of Mars may be liquid water. It is reported by New Scientist, scientists published a paper in the journal Icarus.
As part of research scientists interested in a "greenhouse effect".
Sunlight penetrating through the surface ice, heats the particles present in her soil.
Physics were able to identify so-called hyralnyh metamaterialov reverse the Casimir effect, ie these materials vidshtovhuyutsya convergence of nanometers at a distance. Research article appeared in the journal Physical Review Letters, and its summary is given in the press release Eymsa Laboratory, whose staff participated in the work.
Mathematicians have set a new record density packing tetrahedra. Article scientists published in the journal Nature, as it appears in the brief press release on the University of Kent, whose staff participated in the work.
Dense packing problem - one of the oldest unsolved mathematical problems. A simple formulation of the following: a fixed region of space to fill in as you can in terms of number of major figures. In this respect, the volume occupied by the figures for primary and called the packing density.
Scientists have found about how olfactory in dogs. Researchers working with animals of several species, created a computer model of the dog nose. Results of published in Journal of the Royal Society Interface. Short of them writes portal SCIENCENOW.
