From the Greek "fusis" there is the word "physics". It means "nature". Aristotle, who lived in the fourth century BC, first introduced this concept.
"Russian" physics began with the presentation of MV Lomonosov, when he translated the first textbook from the German language.
Physics is one of the basic sciences of nature. In the world around there are constantly different processes, changes, that is, phenomena.
For example, a piece of ice in a warm place will startmelt. And the water in the kettle on fire boils. The electric current passed through the wire will heat it and even heat it. Each of these processes is a phenomenon. In physics, these are mechanical, magnetic, electrical, sound, heat and light changes, which are studied by science. They are also called physical phenomena. Considering them, scientists deduce laws.
The task of science is to discover these laws and study them. Nature is studied by such sciences as biology, geography, chemistry and astronomy. All of them apply physical laws.
Помимо обычных в физике используют и специальные words, called terms. This is "energy" (in physics it is a measure of different forms of interaction and motion of matter, as well as the transition from one to another), "strength" (a measure of the intensity of the influence of other bodies and fields on any body) and many others. Some of them gradually entered into colloquial speech.
For example, using the word "energy" in everyday life as applied to a person, we can evaluate the consequences of his actions, but energy in physics is a measure of learning in a variety of ways.
All bodies in physics are called physical. They have volume and shape. Consist of substances, which, in turn, are some kind of matter - this is all that exists in the universe.
Much of what people know is from observations. To study phenomena, they are constantly observed.
Let us take, for example, the fall of various bodies to the earth.It is necessary to find out whether this phenomenon differs in the fall of bodies of unequal mass, of different heights, and so on. Wait and watch different bodies would be very long and far from always successful. Therefore experiments are carried out for similar purposes. They differ from observations, as they are specially implemented according to a pre-compiled plan and with specific goals. Usually, in the plan, any guesses are built in advance, that is, hypotheses are put forward. Thus, during the experiments they will be refuted or confirmed. After considering and explaining the results of experiments, conclusions are drawn. So scientific knowledge is obtained.
Often, by studying any physical phenomena,perform different measurements. When a body falls, for example, measure height, weight, speed and time. All this is physical quantities, that is, what can be measured.
Measuring a value means comparing it with the same value that is taken as a unit (the length of the table is compared with the unit of length - by a meter or another). Each such quantity has its own units.
In all countries, they try to useunits. In Russia, as in other states, the International System of Units of SI is used (which means "international system"). The following units are accepted in it:
Often it is necessary to use units that are much larger than the commonly accepted ones - multiples. They are called with the corresponding prefixes from Greek: "deck", "hecto", "kilo" and so on.
Units, which are smaller than accepted, are called "bottom". To them, consoles from Latin are used: deci, centi, milli, and so on.
In order to conduct experiments, devices are needed.The simplest of them are a ruler, a cylinder, a roulette and others. With the development of science, new instruments are being improved, become more sophisticated, and new ones are appearing: voltmeters, thermometers, stopwatches and others.
In general, the instruments have a scale, that is, the dashed divisions on which the values are written. Before measuring, determine the price of division:
For example, two dashes with values of "twenty" and "thirty", the distance between which is divided into ten intervals. In this case the division price will be equal to one.
Measurements are performed more or less accurately. The permissible inaccuracy is called the error. When measured, it can not be greater than the division price of the instrument for measurement.
The accuracy depends on the division price and the correct use of the device. But in the end, in any dimension, only approximate values are obtained.
These are the main branches of science.It may seem that they are very far from each other, especially since most people are either theoreticians or experimenters. However, they develop constantly side by side. Any problem is considered by theorists and experimenters. The first case is the description of data and the derivation of hypotheses, while the latter check the theory in practice, conducting experiments and obtaining new data. Sometimes achievements are caused only by experiments, without the described theories. In other cases, on the contrary, it is possible to obtain results that are checked later.
This direction originated in the end of 1900,when a new physical fundamental constant was discovered, named Planck's constant in honor of the German physicist who discovered it, Max Planck. He solved the problem of the spectral distribution of light, which radiates heated bodies, while classical general physics could not do this. Planck hypothesized about the quantum energy of the oscillator, which was incompatible with classical physics. Thanks to it, many physicists began to revise the old concepts, to change them, resulting in the emergence of quantum physics. This is a completely new idea of the world.
The phenomenon of human consciousness in terms ofquantum mechanics is not entirely new. The foundation was laid by Jung and Pauli. But only now, with the emergence of this new direction of science, the phenomenon began to be considered and studied more widely.
The quantum world is multifaceted and multidimensional, it has many classical faces and projections.
Двумя основными свойствами в рамках предложенной concepts are superintuition (that is, getting information from nowhere) and managing subjective reality. In ordinary consciousness, a person can see only one picture of the world and is not able to view the two at once. Whereas in reality there are a lot of them. All this in aggregate is quantum world and light.
This quantum physics teaches us to see a new(although many Eastern religions, as well as magicians, have long possessed such a technique). It is only necessary to change human consciousness. Now a person is inseparable from the whole world, but the interests of all living things and beings are taken into account.
It is then, plunging into a state where he is able to see all the alternatives, he comes to enlightenment, which is absolute truth.
The principle of life from the point of view of quantum physics is for a person to, among other things, contribute to a better world order.
