Seven Application of the Theory of Relativity in Everyday Life

Since Albert Einstein formulated in 1905, the theory of relativity is considered as one of the most prominent theoretical physics in the whole of the 20th century. In general, this theory speaks of three basic laws of physics.

Firstly, there is 'absolute' that can be used as a reference or a frame of reference in determining things. Including when measuring the speed, momentum, and the passage of time experienced by an object. There are always things affect these conditions. Second, the speed of light is always the same, regardless of who or how fast the person is measured. Third, there is no faster than the speed of light.

The laws of physics are contained in the theory of relativity even this was to be found in everyday life. The theory of relativity is considered to have profound implications in our daily lives. Here are seven of the application of the theory of relativity in everyday life, quoted Livescience.com page:

electromagnetic
If you do a loop of wire and move it to the magnetic field, then you will produce an electric current. The particles are electrically charged influenced by the magnetic field, which forced the particles that change and move creating an electrical current. However, when the wire is not moved, the particles in the wire (electrons and protons) is no longer moving. The magnetic field also affects the particle considered. Nevertheless, there is still electricity flow are created. That is, no specific terms of reference which influence the emergence of the electric current.

Professor of Physics of the University Pomona, California, Thomas Moore, said the condition of Faraday's law asserts issue, stating changing magnetic field creates an electric current. '' This is the main principle of the electric generator. Anyone who uses electricity in daily life actually have felt the effects of relativity, '' said Moore.

Global positioning system (GPS)
The working principle of GPS uses satellites and ground stations are also considered to use the effects of the Theory of Relativity. To get the GPS location accuracy to users, the satellite will transmit the data to a ground station and then an earth station will forward it to the GPS device respectively. Level of location accuracy is due to the effects of relativity.

Satellites in space at a distance of approximately 20.300 km from Earth and moving at a speed of 10 thousand km / h. This causes the difference in 'time' between the earth with satellites, which reached 4 microseconds. Coupled with the effects of gravity, then the difference becomes 7 microseconds.

If there is no difference, then the effect will be felt dross. If there is no relativity, the GPS will mention the distance to the nearest fueling station reaches 0.8 km. In fact, the actual distance bia reached 8 km.

Golden yellow
Most metals sparkling seemingly because electron in the metal atom is beyond the 'orbit'. This is because electrons have different energy levels. While gold has a heavy atomic mass. So the electrons in it moving very fast and enough to increase the relativistic mass and length are exhibited significantly. As a result, the electrons around the atomic nucleus with a shorter distance.

Electrons that are outside the orbit of the atomic nucleus is finally absorbing and reflecting the colors that have a longer wavelength than blue. Yellow, orange, and red does have a longer wavelength than blue.

Gold does not corrode
Relativity in gold electron is also the reason why gold is not quickly corrode like metals in general. Gold being the only metal that has electrons are outside the nucleus. However, electrons are not easily react gold as the lithium and calcium. In addition, gold is also quite heavy electrons and close to the atomic nucleus. That is, electrons are outside the nucleus of the atom not being as electrons present in other types of metals.

Mercury is a liquid
Just like gold, merkurin also have a heavy atom. Electrons in mercury are also quite heavy and tend to be closer to the nucleus. Mercury also has a weak atomic bonding, so that the visible mercury melts at low temperatures while.

television tube
In the past several years, televisions and monitors still have a cathode ray tube. This cathode ray tube firing electrons into the phosphor surface with magnets. Each electron will form the color pixels on a television screen or monitor. This electron movement speed reaches 30 percent of the speed of light. At this point, the relativistic effects can be detected in the working principle of the televisions and monitors.

Light
Related to this, Moore had no explanation why light is also a proof of the theory of relativity. '' Not only the magnetic field, the light will not we know as
