Tip 1: How to understand the complex laws of physics

Physics is not an easy science, and understand it laws often it is quite difficult. If we realize that physics is inextricably linked with living nature, and learn to draw a parallel between physical concepts, theories, definitions and nature, it is easier to understand even such a complex subject as physics.

Instructions

Start learning physics With the simplest laws of nature, for example,"The dependence of the gravitational force on the square of the distance", and try to represent it geometrically. Refer to the special literature designed to facilitate your understanding of physical laws. To such books it is possible to carry: "Entertaining physics" Perelman J., "We discover the laws of physics. Mechanics »Gendenshtein LE, Kurdyumov ML, Vishnevsky EI and "Science and the amazing. How a person understands nature. "Weiskopf W.

Understand that the laws of physics are certainThe rules by which the world lives. If you realize that scientists are only exploring the principles of life on Earth, the laws of physics will become more accessible to your understanding. Feel that around you reigns a secret order at all levels of the universe. When you want to solve the riddles of nature, you will become interested in physics. With the desire to get knowledge to study the laws will be easier. Learn to appreciate the work of researchers, because without them, progress in science would not be possible. Be inquisitive. Start thinking in the direction of studying the work of technical devices, which we are used to take for granted. You will see that a whole new world will open before you. The laws of physics are used in many cases. She explains why you can not add water to the boiling oil, why on the horizon we see the twinkling of the stars, for what reason the water, flowing out of the bath, twists, why the whip snaps. It is very useful to learn to see the physical laws in life.

Try to see how the laws of physics helpExplain what is happening around, generalize some facts and predict the future. Behind the physical formulas are hidden laws that even nature itself does not dare to violate. Living in a simpler world from the point of view of understanding, knowing why these and other phenomena occur, and what can be expected in different cases, you will feel more confident. Once you are asked the next question about the causes of a phenomenon, find the answer to it with the help of physics. Such discoveries as the electromagnetic field, the relativity of time and space, the mechanical theory of heat, the definition of an expanding universe, help to understand many facts.

Tip 2: Which tires are better in winter: spikes or velcro

To make the right choice, you shouldto familiarize with the features of each of these types of tires, to find out how they behave on the road in conditions of snow porridge, ice or mud. Knowing the structure and quality of rubber will allow you to decide which tires to buy.

Talk about what kind of coverage for tiresuse in the period of snow and ice, a lot. Every experienced car owner has his own opinion on this score, which he considers solely authoritative. Sellers of the goods can tell so much about its unique properties that it is right to revise the laws of physics and chemistry. Therefore, the best counselor is an objective analysis and your own mind. To understand what tires are better, you first need to understand why the ice is slipping. The reason for this is the water film, which arises from the force of friction and heating. Unlike the summer period, when the tire also gets into the wet environment, but quickly dries up, in winter, a layer of ice is formed on the surface of the rubber. The relief of the tread is smoothed out, it becomes harder and it is more difficult for it to catch on the unevenness of the road.

About "Velcro"

In fact, these tires do not have that property,which brings the association from their name. "Velcro" is nothing more than competent marketing. They do not stick and nothing sticks to them, they are ordinary frictional (without spikes) tires, but slightly improved for movement in the cold season. Manufacturers of non-studded tires make rubber from a mixture with additives of quality plasticizers. It becomes softer, which allows the wheel to better repeat the unevenness of the road. In "Velcro" this principle of patency of the tire is used: they are softer than the studs and they squeeze liquid out of the depressions faster, preventing it from freezing.

About the "thorns"

Protector of modern studded tires -multilayer. To ensure that its blocks are harder, and the area in contact with the road is soft, the inner layer is made rigid and the outer one is plastic. Externally, all studded tires seem to be the same, but in fact there are different protectors. They have one thing in common: spikes are made of more rigid rubber than the inner layer of the tire.

Operational issues

On the conditions of ice, an indisputable advantagespiked: they know how to "bite" into the ice, strengthening the grip on the road. But where there is no ice, the spikes do not allow the rubber to tightly press against the road surface, thereby reducing the area of much needed contacting. If in the region of residence the frost is more than -20, then the ice on the roads becomes very strong and the efficiency of the studs decreases, since they can not stick to it anymore. In this case, the optimal choice - "Velcro", because they to improve contact with the road does not interfere. At high frosts, such tires start to work better, because the water film does not practically arise from the heating of solid ice. For this reason, the coefficient of friction increases. But during the thaw again the advantage behind the "spikes". Given the region of residence, weather and road conditions, every car enthusiast should decide for himself which tire choice will be optimal for him.

Tip 3: How to improve your memory

It is very important for a person to be guided ina huge flow of information, to be able to systematize it and remember what it needs, so it needs a good memory. And it can not only be trained, but also reasonably used.

There are some ways that will help to develop memory and make fuller use of its capabilities:

1. Learn to find what you need in memory.

When you need to remember something, it's best not totry to reproduce something concrete, memorized, and remember ideas, options, or something close to what needs to be remembered. This well trains memory, because it leads to an active state of neural connections, directly related to the idea you need.

2. Correct information processing.

It's like stringing beads on a string - whennew knowledge as it were "attached" to the already existing, they fall on them as a basis. And if you remember one element from this chain - you can play the rest. The main thing here is not to learn, but to understand the information and attach it to the already available information.

3. Study of different subjects.

When a person studies several subjectsat the same time - he is able to track the interrelations between them, and he develops a whole picture of the world. After all, the laws of economics, for example, work in many spheres of life, like the laws of physics. Realizing this, it's easier to remember the most complicated things.

4. Find the answer yourself.

When a person takes up an unknown job andfinds a solution on its own - it acquires an invaluable experience in generating ideas and independently searching for a way to solve a particular problem. This inspires confidence in their strength and trains the brain.

5. Analysis and assessment of what is happening.

While working on the project, it's useful to distract the task for a while and analyze the progress of the work by answering the questions:

What was done successfully?
What can be improved?
What is the conclusion from this?

It is very effective every day to conduct a short analysis of the day with the help of these questions - this greatly increases the efficiency of the work. And the ability to analyze for the development of memory is simply necessary.

6. Association for memorization.

Each association has its own, so you need to choose something that will help you to remember complex things. It can be colors, smells, poems, memories or something else.

7. Make sure everything is understood correctly.

Do not be afraid to ask again - did you understand thatessence of information. Often it may seem that everything is clear, and later there are many questions and incorrect interpretations of knowledge. Therefore, it is better to ask again, than to receive distorted information that will enter the data bank of your memory.

Tip 4: How to translate idioms

The idioms of any foreign languagetranslation of special difficulties, since they can not be translated directly. The interpreter needs to carefully approach the translation of idioms in order to correctly convey the meaning to the reader or listener.

Instructions

Idioms are phraseological phrases,present in most languages. In an idiom, in most cases, you can not rearrange words, add new ones, or remove existing ones. Its translation does not depend on the aggregate values of all the words of the expression. That is, translate the idiom according to words will not work, there will be no meaning in the resulting expression, or it will be distorted. To translate an idiom it is possible only on its initial value inherent in all this phrase entirely.

For the correct translation of the idiom it, first of all,must be recognized in the text or speech. If some expression seems strange in meaning, it looks unnatural in context, violates the laws of language, physics, or simply does not translate - there is a high probability that you have an idiom in front of you. For the translation of idioms there is a large number of phraseological dictionaries, both paper and electronic. The erudition of an interpreter will also help in this case, but if you do not know the exact meaning of the idiom, it is better to turn to reliable sources, otherwise there is a risk of misunderstanding and translation of the expression.

When translating idioms, you need to pay special attention toon the context, since many idioms look very similar to ordinary expressions. For example, a phrase such as "go out with" can be translated as "go out with someone to walk", and how to "roll up your sleeves."

After recognizing the idiom it follows the mostadequately convey in the text or speech. To do this, one must have in-depth knowledge of not only a foreign language, but also a native one, and feel the language well. Let us assume that the same idiom in written and oral speech can be transmitted in completely different ways. And even if it's only a written text, you need to be especially careful with the style when translating idioms. Thus, in the text describing the life of people in the 19th century, the idiom will be translated differently than in a modern novel intended for teenagers.

For the correct translation of idioms, one must look atthe meaning of this expression for a foreign language, it is well to understand the importance of this idiom in the life of native speakers. Then, if not equivalent, then the closest idiom or expression in the target language should be selected. They can differ widely among themselves by language means and even be different in intonation and the way they are reported. But the semantic coloring of the original and translated expressions should be similar.

The translation of idioms is one of the most difficultmoments in a foreign language. If it is impossible to correctly convey the meaning of the idiom, or its analogs are not in the target language, it is possible to skip it in translation, provided that the author retains the style of the text and the meaning of the expression.
