The Red and the White Saar have their sources on Donon, less than distance apart. The source of the White Saar is near the town of Grandfontaine (Bas-Rhin department), and the source of the Red Saar is near the town of Abreschviller, (Moselle department). The confluence of the two rivers is near Hermelange (), south of Sarrebourg.
The Saar river, and its two source rivers, flow first through the Moselle department, in the Lorraine region; then, for a short distance, flow through the Bas-Rhin department, in the Grand Est region. From Sarrealbe to Sarreguemines, the Saar flows along the border with Germany. At Sarreguemines, the Blies river, the largest tributary of the Saar, flows into the Saar and its discharge rises from 20.9 m³/s to 41.5 m³/s.
From Sarreguemines, the Saar is (it is deep, wide and slow enough for a ship to pass). Then the Saar gets into German territory forming a narrow valley through the western Rhenish Massif. At its beginning in this region, it forms the famous Saar loop (German: "Saarschleife") at Mettlach.
After 246 km (129 km in France, and 117 km in Germany) the Saar flows into the Moselle river at Konz (Rhineland-Palatinate) between Trier and the Luxembourg border.
Grapes, to produce wine, are grown along the lower Saar, mainly between Serrig and Konz.
Some of the important tributaries of the Saar are:
Some towns and cities found along the river are:

Konz is a city in Germany. It is on the Moselle River.

Simple living
Simple living means to choose a lifestyle where you own fewer things and focus on what you need instead of what you want. People choose this lifestyle for many different reasons, often based on their views on health, economy, or philosophy, or because they want to protect the environment. Some people do it simply because it suits them better.
Some famous people who chose the simple living lifestyle are Francis of Assisi, Leo Tolstoy, Rabindranath Tagore, Albert Schweitzer, Mohandas Gandhi, and Henry David Thoreau. The Amish live simply by using only things that are described in the Bible.
Meteor burst communication
Meteor burst communication uses radio waves which bounce off the ionized trails made by meteors as they enter the earth’s atmosphere. It is also called Meteor scatter communication.
Meteors are lumps of rock which are floating about in space. There are always meteors which are entering the earth’s atmosphere. They normally burn up in the atmosphere. A few very large ones that hit the earth are called 'meteorites'. Most meteors are only tiny specks of dust. As they enter the atmosphere the heat made by air friction rips off electrons. This produces an ionized trail. This trail can reflect radio waves in the same way that a wire would.
The meteors that are used for meteor burst communication are between one thousandth and one hundredth of a gram. Meteors which are smaller than this are too weak to be used. Larger ones are not frequent enough.
The ionized trail can last for several seconds. During this time messages can be sent between two radio communication stations. The messages will be transmitted very fast: about 200 times as fast as with ordinary shortwave radio communication. A teletypewriter may type several lines of text during a meteor burst. The two stations that want to communicate will have to be ready all the time as they never know when the next burst of communication will come. They may have to use several meteor bursts before the whole message is received. The transmitters are often put on buoys in the sea.
Meteor burst communication was first widely used in the 1950s. It was particularly useful for military communications, because a receiver could not tell exactly which direction the message had come from. This was because the message was reflected on the way, so it did not travel in a straight line (i.e. in a simple great circle round the earth’s curve).
The use of communications satellites in the late 20th century has made meteor burst communication rare.
Hole
A hole is an empty space in a solid object, which can be flat.
It can also mean other things:
Spyware
Spyware is a category of software for computers. Spyware is malware that collects some data, usually without the computer users' knowledge. Very often, this data is then sent over the internet to someone else. Very often, this is used for marketing. Spyware can also be used to steal data from computers. One kind is a keylogger which can see whatever you are typing. Keyloggers can steal important information like passwords that you type.
The best protection is to get a program that protects against spyware. But be careful, many websites that claim to have them are actually spyware, not something to protect against it. This method of installing spyware is called a Trojan horse which is disguised as something useful but when it runs, its keystroke logging sees what keys you press. This makes it easy for the trojan operator to collect your passwords and important data and log into your accounts. Spyware tracks your computer and uses some of the things on it. This includes your files, your downloads, and usernames/passwords for websites and programs
There are spyware applications that are designed to enable users to spy on themselves rather than others. This is called myware. The term myware has mainly been applied to software applications in three areas: social networking, marketing and time tracking.
Vector space
A vector space is a collection of mathematical objects called vectors, along with some operations you can do on them. Two operations are defined in a vector space: addition of two vectors and multiplication of a vector with a scalar. These operations can change the size of a vector and the direction it points to. The most important thing to understand is that after you do the addition or multiplication, the result is still in the vector space; you have not changed the vector in a way that makes it not a vector anymore. A vector space is often represented using symbols such as formula_1, formula_2 and formula_3.
More formally, a vector space is a special combination of a group and a field. The elements of the group are called vectors, and the elements of the field are called scalars. Vector spaces are important in an area of mathematics called linear algebra, an area which deals with linear functions (functions of straight lines, not curves).
A vector can be represented graphically with an arrow that has a tail and a head. To add two vectors, you place the end of one vector at the head of the other one (see figure). The sum is the vector that goes from the tail of the first vector to the head of the second.
"Scalar multiplication" means that one vector is made bigger or smaller (it is "scaled"). Scalars are just numbers: if you multiply a vector by 2, you make it twice as long. If you multiply it by 1/2, you make it half as long.
The "vectors" don't have to be vectors in the sense of things that have magnitude and direction. For example, they could be functions, matrices or simply numbers. If they obey the axioms of a vector space (a list of properties a vector space needs to satisfy), you can think of them as vectors and the theorems of linear algebra will still apply to them.
There are some combinations of vectors that are special. A minimum set of vectors that—through some combination of addition and multiplication—can reach any point in the vector space is called a basis (of that vector space). It is true that every vector space has a basis. It is also true that all bases of any one vector space have the same number of vectors in them. This is called the dimension theorem. We can then define the dimension of a vector space to be the size of its basis.
Basis (linear algebra)
In linear algebra, a basis is a set of vectors in a given vector space with certain properties:
