a person often is in possession of the compass?In fact, not everyone has it even just.But surely many people have been cases where it was necessary to quickly navigate in unfamiliar terrain.No matter for what reason: whether the person was lost during the campaign, whether it is necessary to predict where it will be sunset in order to impress your other half overlooking the flooded with golden light a city, whether it's idle interest - in any case, this skill neverIt will not be superfluous.So, how to identify the part of the world without a compass?It is necessary to understand the following ways.
If it happens in the natural surroundings, you need to find a long straight stick.The bigger, the better.Then you need to stick it in the ground.At the end of the resulting shadows to make a mark.Then wait ten or fifteen minutes - the shadow will move a certain distance.Make a new mark.Connect it with the
To determine the points of the compass by this method requires a sunny day and the usual hours with arrows.Should "aim at" the hour hand at the sun.Then divide the angle between it and the number 1 (if winter) or 2 (if summer) half.The resulting segment will form a north-south line.However, if the clock is not present, you can do without them: either use their imagination, or draw a face on the ground.
If the compass is not, but a man has managed to get lost at night, and he has good vision, he can use the following method.First of all, you need to find the North Star - it is at the end of the "handle" Ursa Minor.If this had some difficulties at first, you can find the Big Dipper.From the two extreme stars (so to speak, the right "bucket wall") to mentally draw a straight line, and a few times on it to measure the distance between two extreme points of the notorious.The fifth raze (approximately) straight points to Polaris.Then nothing complicated - if you stand to face her, would come north.
Since the southern hemisphere do not see any Big Dipper or the North Star, have to settle for another constellation.It is necessary to find the Southern Cross.This constellation of five stars, four of which (the brightest) to form a cross-shaped structure.After two stars forming the long axis of the cross, it is necessary to hold an imaginary length of which must be four times longer than the distance between the above two stars.From the end of the segment we draw a line perpendicular to the ground.She will point to the south.Another way - to wait until the long axis of the cross itself will "look" perpendicular to the ground.
If needed to determine the points of the compass, while in the apartment, and have access to the World Wide Web, just enough to take advantage of services such as, for example, GoogleMaps or Yandex.It should find your home (or your current location).Next, navigate to the map, which is always marked sides of the world, it is very easy.
can simply use their own observations.Again, it is best to be guided by the sun.For example, remember that the sun is always moving across the sky from east to west.So the case for small - to note in the morning, where the sun rises, or vice versa, in the evening - where sunset happens.Actually, not necessarily even this - watching the movement of the sun a certain period of time, with proper eye estimation is quite easy to predict where it has risen and which sits.However, we must not forget that this method is quite inaccurate, and in cases where undesirable errors, it is better to use other ways.
Finally, mention should be made about the other natural landmarks that allow you to determine the points of the compass.For example, normally moss grows on the north side;branches of the trees on the north side are growing rarer nests are usually arranged on the south side;Mushrooms tend to grow on the north side of the tree.Another good indication - birds.In the fall, they fly north in the summer - in the south.
