Through the boundaries of classical physics: quantum mechanics properties of light are shown

In physics there are two categories: classical physics and quantum physics. In classical physics, an object such as a car or a ball, has a position and velocity. This is how we classically see our everyday world. In the quantum world, objects can also have the position and velocity, but not at the same time. Not merely because we do not know the position and velocity, but, both of these things did not exist simultaneously. But how do we know if they do not exist simultaneously? And where is the border of two worlds? Researchers have discovered a new way to answer this question.Light on quantum mechanics"Our goal is to use quantum mechanics in new ways. It is important for us to know if a system does not behave can have a classical explanation. On this side, we first examine the light, "said Eran Kot, a PhD student in the research team, Quantum Optics at the Niels Bohr Institute University of Copenhagen.Based on a series of experiments in quantum optics lab, they examine the state of the light. In classical physics, light has electric and magnetic fields as well."What our study shows is the light can have a magnetic field and electric field, but not simultaneously. We then give a simple proof that the classical principle of breaking experiments. It can be said that if we show that the quantum properties of light, and we can expand this to other systems as well, "said Eran Kot.Classical mechanics and non-classicalThe purpose of this study is to understand the world fundamentally, but there are also practical challenges to exploit quantum mechanics in a broader context. For the light it is not surprising that it behaves quantum mechanically, but other methods are also being developed to study other systems."We are trying to develop quantum computers of the future and we therefore need to understand the limits where something behaves quantum mechanically and when he behaves mechanically classic," said professor of quantum physics, Anders S Sorensen, explaining that quantum computing should be composed of systems with non-classical properties .News source: University of Copenhagen.Reference journal:Eran Kot, Niels Grønbech-Jensen, Bo M.

Found, Giant Deer Shaped Stone Structures

Motif is a huge stone stretching over 275 meters. Starting from the furthest point in the northwest to the southeast. 

A man named Alexander Shestakov accidentally found a giant motifs made ​​of stone (geoglyph) form of deer on the Russian soil. The findings are then forwarded to the scientists that eventually led to the excavation led by Stanislav Grigoriev of the Russian Academy of Sciences Institute of History & Archaeology.

This giant motif located near Lake Zjuratkul, in the Ural Mountains, northern Kazakhstan. It looked like a deer with a muzzle, four legs and two horns. Even the satellite images of Google Earth in the year 2007 shows a tail. However, this form is more unclear in recent photographs.

Without counting the tail, a huge stone motif stretches along 275 meters. Starting from the furthest point in the northwest to the southeast. This is the same stretch of double-wide American football field. This motif is facing north and can be seen from the ridge of the hills nearby.

"This motif looks white and a little shine when compared to a background of green grass," wrote Nikolai Grigoriev and Menshenin, of the State Centre for Monument Protection, as reported in the journal Antiquity Thursday (11/10).

Research indicates if geoglyph is the product of the megalithic culture. In addition, the team led by Grigoriev discovered that the motive is very complicated.

However, there is more to the excavations carried out in this geoglyph because it feared it would ruin motif. Added to this is if geoglyph this is not the first in the Ural region, as also found hundreds of other megalithic sites in adjacent locations.
