The compass is the most valuable invention, but at hand it is kept only the units of us. And if it was even lucky to be in an unknown area with a wonder-device, he can show the direction of the magnetic north, and not accurate. And then additional information from physics and natural science will be useful.
1
Watch over the sun throughout the day. It always gets up in the east, it comes in the West. Accordingly, turning the face to the east, you will get the West behind your back, on the right hand - south, and on the left - north.
2
With solar weather, it stick to the ground to a smooth stick, preferably high. A few hours before noon and some time after it, measure the length of the shade, which the stick throws away. At the moment when the shadow is the shortest, the sun will be in the zenith and the shadow will indicate the exact direction of the south. So, on the back of the north, right - west, left - east.

If you have a watch, turn the dial so that the short arrow pointing at the sun. Carry out a segment of an imaginary center hours to 12 digits, then the resultant angle mentally divide in half. This line indicates the south. In an area where summer time is translated by one hour, the segment should be connected to the number 1, but only in the months of real time timing.

Night orient in space will help the starry sky. Find the Big Dipper. The two stars that make up the far side of the handle of the bucket, connect direct. Set aside five more distance in the direction of the tail of Ursa Minor - and get to the North Star. It was she who shows the north.

The compass function can perform a needle. Throw her about the magnet to transfer it a magnetic field. If there is no such subject near, but there are scissors, quickly cut the air, and then sweeten the needle about metal tips. Next, lubricate the needle with vegetable oil or put on it a piece of foam, lower the design into the water. It will accommodate exactly along the North-South line, but to determine which of the two sides is the North, will have to be using additional methods.

Modern technologies will help find the right direction. There are special mobile applications for mobile phones, such as Smart Compass, where after simple settings information about light sides is displayed. When accessing the Internet, you can use the programs like Google Maps. Find your location here or refer to the nearest settlements, and the map will show the terrain in the usual format: at the top - North, below - the south, right - east, left - west.

Indicate on the sides of the world also some features of the surrounding nature:
moss grow well on the northern part of the slopes, stumps, stones;
the anthill stands south of the nearest tree or bush;
with sultry weather on coniferous trees, more resin from the south side;
snow melts rather on the southern hillside;
in the summer, near the soil elevation is woeful in the north;
migratory birds in the spring fly to the north, and in the fall - in the opposite direction;
mushrooms are more worst on the northern part of the tree;
on the mountain in the southern region, the northern slope is covered with beech, fir, fir, and the southern - pine and oak.
If the side of the light is required to determine especially accurately, use several methods at once from the above. Be sure to need additional verification data obtained from nature observations.
