The sunstone, a translucent crystal composed of minerals known as Iceland calcite, may have been ayır surprisingly successful ve in finding directions because it separates the polarization of the light passing through it. This is an argument that is considered to be directly related to the discovery of the rare sun in the North Atlantic Ocean in cloudy weather.
The Vikings do not use a magnetic compass to find directions at sea, and are even thought to have no information about the compass.
According to optical physicist Dénes Száz, the lead author of the study published in the Royal Society of Open Science , several Viking settlements established in Greenland after the 10th century seem to have been created with the help of the crystal sunstones.
According to Száz, it was shown by computer simulations that the Vikings could control the position of the sun every 3 hours, which could have sailed to the shores of the Greenland, ie to the west.
On the other hand, the Vikings who control the position of the sun much more rarely, if they have lost their lives by disappearing at sea, they may have been dragged to the south (the Canadian coast) by kidnapping Greenland.
Száz said, ın According to the archaeological finds, we know that the Vikings were in North America centuries before Columbus. But what we don't know is whether the Vikings have reached the North American shores as a result of a mistake, or they've gone on exploratory expeditions before the colonies in Greenland. Fakat

Mystery of the Viking Sunstone

In the new study, Száz and co-author, Gábor Horváth, conducted 36,000 computer simulations in the North Atlantic to find out the estimated routes that Viking ships could follow by following the sunstone.
The research is actually a study of many semi-transparent crystals such as Icelandic calcite, based on studies focused on measuring human errors in previously constructed and monitored routes, investigating whether a bright one or only two images are present, depending on the polarization.

According to Száz, it is not a proven fact that the Vikings used the sunstone, but actually proved to be of archaeological finds. This information is entirely in the 13th century. Describes an Icelandic epic written by Olaf ( referred to as the former Izlenadacada sólarsteinn ) to find the position of the sun on cloudy and foggy days.
Vikings are thought to have used a non-magnetic solar compass to measure the angle of the sun at noon. As a result, they could be directed to a fixed line in the direction of latitude, ie from Norway to west - to Greenland.
But since the North Atlantic has cloudy and foggy weather in the majority of the year, the sun cannot be seen for days or even weeks.
According to a hypothesis put forward by the Danish archaeologist Thorkild Ramskou in 1967, the Vikings, by turning the sunstone into the sky on cloudy days, were able to determine the position of the sun, depending on where the images or sparkles in the crystalline fell.

Simulated sea cruises

According to computer simulations, especially when the observations are taken every 3 hours and at noon, the position of the sun in Viking voyages can be determined even on cloudy days.
According to Száz, the simulations show that the Vikings, who have remained loyal to the observation charts, may have reached the shores of the Greenland from Norway in three or four weeks. Arasında If the direction-finding period is 1, 2 or 3 hours, we have shown that the probability of finding the intended direction is between 80 and 100 percent, bulma says Száz.
The research also showed that the Vikings, who never do sun observations or do it every 6 or more hours, tend to sweep Greenland away, moving southwardly.
If the Vikings, who had joined the expedition, were not destroyed because of thirst, hunger or storm in the sea, and they were dragged south, they went straight to the shores of Labrador and Newfoundland, Canada, says Száz.
The computer simulations used in the research focus on the climate change, the types of minerals that can form the sunstone and the point that the year takes into account the periods of Norway - Greenland flights.
In the study to be carried out in the future, it is stated by Száz that the simulations will include factors such as the effect of lightning, ocean currents and variable wind.
