In chemistry, all the elements of a "sort through" in Mendeleev's table. In biology, all life is distributed by Carl Linnaeus in the genera, species, family, etc. In grammar, all words are neatly divided into parts of speech and the sentence. And that Physics? Only elementary particles in the twentieth century was laid in, and this has led to new discoveries. A routine physical quantities, which innumerable and enjoyed by millions of people in everyday life – for them the system is not. All known SR – is not a system, it is simply an international agreement on what units of measurements considered essential (kilogram, meter, second, and four more units), and all the rest is on them. Guide creation of the SI one: it was convenient and relatively cheap to measure. And when ordering must be guided by the laws of nature, even if it is inconvenient and expensive.

Now physics reminiscent of an army victoriously rushing forward and are gaining more and more new frontiers. But in the baggage of the army and its statutes carefully preserved all that was reached two and even three centuries ago, with the same names and with the same symbols. Although much has long been obsolete, needs to be revised in line with new developments. And then it becomes clear that the mass measured in kilograms, is the principal value only at the earth's velocity and terrestrial equipment. A-level velocities close to the speed of light, the same mass estimate is in units of energy.

But, perhaps, traces of the Big Bang can be found by looking in the distant past of the universe? Observational astronomy is now able to see objects placed on us by distance of more than 10 billion light years. These are objects that existed 10 billion years ago. According to the Big Bang theory the universe and the visible part of it, called Metagalaxy, then was much smaller and galaxy it would have placed much more closely than at present. But observations show that galaxies and their clusters in time and space are distributed fairly evenly and there is no evidence that the expansion of the Metagalaxy is explosive. You can calculate approximately how fast expanding Metagalaxy. The Hubble constant is about 100 km / sec. 1 Mpc (3 million), or 3 * 1019 km.

Imagine it’s an astronomical distance as a line length of 1 meter. Then, after 1 million years, this line will be longer than 0.1 mm after 1 billion years – 10 cm and only 10 billion years it will be twice as long. In nature it is difficult find examples of a slow process. The more difficult to call a speed burst. In fact, the galaxy is very slow crawl. But even for such a motion need enormous energy, which in space could just put a star. Emitting enormous amounts of energy, some of it can transform into a star field of spatial, vacuum.

You create their own look, you choose how you will see other members of virtuality. You can be simultaneously in many of the virtual. You can always break off without any loss of connection in virtuality and immerse yourself in another virtual. No problems so treplyuschih nerves in the outside world. Want to shoot – please shoot, make love – not a question, get together and discuss how an issue is not a problem.

With each passing hour things are not available in virtuality is becoming less and less. A man passes from the outside world, full of challenges and frustrations to the world of made-up rules which are much more liberal and that it can always be first all depending on any of its data. What is the outside world? This is what we see, feel, feel! Modern electronic devices can affect almost all organs of the human senses, simulating the reality of all better and better. It should be noted that such a symbiosis of man and machine is getting closer thanks to modern advances in electronics. To be unfounded, we consider two aspects in which the virtual moved beyond all: the game and love (sex). Games Here’s the real plague of the 21 century. Spending a lot of time man, they almost do not carry any payload other than satisfaction. Nevertheless, the logic is not there advantage of the human race. Games – a source of positive adrenaline is so lacking in today’s world.

No knowledge of the law – not an excuse. This statement applies not only to state laws, but also to the laws of life. The man who owns the laws of success, even after losing everything, soon will once again be "on a horse." Those who accidentally bought their goods again soon left with nothing. Successful from not successful, the person is different, first of all, the scale of the individual. Because someone who is not ready for it, even knowing all the secrets, and they will not apply and remain at the same place. Learn more about this with Euro Pacific Capital. Agree: the courage, take risks, make a move to take responsibility for the outcome of their actions, to correct the mistake and do the action – is not everyone can. How many secrets at once: to take responsibility, take risks, work, learn from mistakes … Learn more on the subject from Benjamin Wey Financial Times.

Like all well-known steps, and who makes them? And how many people realize that these simple steps and basic secrets lie? After all, these secrets are taught to every step, only few who make them. Who does not believe that everything is so simple, but some can not, for several reasons. That these reasons, we will contact you gradually and will deal on this blog, step by step. Every day, every minute we accept some decisions: what to read, with whom to communicate, what to do, etc. That our actions are responsible for the results that we have in life. One of the laws of the universe is responsible for success and not success in life says, what you did yesterday, brings you to what you have today.

Word balloon, sky, flying show the articulation of the lips.

While the boundaries of such a neighborhood does not specify I will not. Now, if a fraction of the speed of light set the speed point of L, then we can try to get a coordinate transformation. Legend speeds leave familiar (because you can keep in mind: V = c / n, where n – a number greater than 1, and c = 1. Now we use the postulates and conclusions of the special theory of relativity (SRT) and the requirement of orthogonality coordinate transformations. Orthogonality is required to maintain records of our species invariant – the interval. We've all properties are preserved for inertial reference systems (ISO)? Therefore, if the pseudometric (our interval) recorded in orthogonal coordinates, and the other pseudo-ISO must exist in orthogonal coordinates. Hence we can always compare the terms of the ISO in orthogonal coordinates.

This requires orthogonal transformations to the point of one of the orthogonal coordinate system were transformed into points of the other orthogonal coordinate system. The general form of transformation is written as a system linear equations. It’s believed that Euro Pacific Capital sees a great future in this idea. By analogy with the SRT, this system of equations is trivial transformation takes the following system of equations: acq '= Acq + Bx ax' = Ccq + Dx ay '= Ey az' = Pz, where c – speed of light, and a, A, B, C , D, P, E – the coefficients of the variables, and we look for them. For simplicity, we consider only the first two coordinates (this does not change the generality of the arguments).

The situation is exacerbated by the fact that being in this part of the river Kosi barrage Coastal levees did not stand the water pressure, and it broke on the surrounding area. In West Africa, about 150 thousand inhabitants of Benin, 45 thousand people in Niger and another 12 thousand people in Togo were forced to flee their homes because of floods caused by heavy rains. It is possible that these numbers could increase significantly, given that the rainy season here continues usually until the end of September. On the island of Bali, discussed ways to maintain the population sea turtle last week on the Indonesian island of Bali as part of the UN Environment Programme (UNEP) held a meeting of States Parties of the Memorandum of Understanding concerning the conservation of marine Turtles and their Habitats of the Indian Ocean and Southeast Asia. Representatives from some 30 countries discussed measures that will stop the rapid reduction in population of sea turtles in some regions. Despite the fact that over the past 40 years in many countries in southern Africa, an increase in the number of sea turtles, heavy-headed, in other regions such as Australia and Madagascar, the marine life were in danger of extinction.

Experts believe that the rapid development of human resources and marine coastline has a negative impact on changes in the natural habitat of turtles. Such activity limits their ability to reproduction. Nowadays, these animals were difficult to find a quiet secluded beach, where they can lay eggs and produce offspring. Another enemy of turtles is fishing – getting captured fishing nets, these animals As a rule, can not get out of their own and die. Many long-lived turtles often die as a result of the deprivation of their natural habitat. Scientists have shown that the behavior of the birds affected by global British Ornithologists warming as a result of long-term studies of birds came to the conclusion that because of global warming, some species of birds in the UK have begun to lay their eggs much earlier than was 40 years ago.

For example, under the impact of climate change, chickadees, finches and blackbirds have started laying eggs ahead of time and hatch them only to premature warming. As a result, the number of specimens of these species, compared with in 1970, halved and the number of water birds, in contrast, has increased. Ornithologists believe that birds have to adapt to climate change in order to survive. It turns out that birds are warning us of the consequences that may occur in connection with future climate change. Similar changes in behavior were found not only in birds but in mammals, insects and even plants. According to scientists, for crops of climate change pose a great threat, but some species of birds are quite capable to deal with them. Scientists fear that in addition to natural climate change, we are facing a sharp warming caused by human activity, which has a significant impact on the stability of climate on the planet as a whole. As a result of this change of behavior of birds, and as mammals, insects and plants will become even more pronounced. Breathing city air as harmful as smoking Scientists from Louisiana State University (USA) came to the conclusion that

It is important to mention that the thought processes are not detached from the metacognitive strategies as these require us to be aware of the tasks performed have a knowledge of procedures for its implementation and to check constant in order to identify whether the actions are in line with objectives. The observation i accomplice to identify the characteristics and stimuli of objects and situations through the senses and the integration of these into a whole that represents the mental image of the object, ie observation, in the first place of the meeting raw sensory data, and then, its content, ie what one has seen, heard, understood, felt, etc. The observation process is a process of permanent identification of the subject with its environment. There is an abstract level that refers to variables that are not, but that are predicted; note is talking about and how it has different levels: concrete, abstract, directly and indirectly. Visit Peter Schiff for more clarity on the issue. The individual learns through observation of their environment, guided by questions ranging from general to particular.

The description is the process used to represent objects, people or situations through written language, visual or verbal, is to list and orderly integration of the different qualities or properties that form the subject of an alert. The descriptions can be concrete or static when appointing only the components of a graph or situation point to point, without integrating the data and characteristics of what is observed. They are dynamic or more complex, as also set out actions and the characters are linked together, attributing emotions, ie when the construction of the description made so spun, this type of description is important for strengthening the level of understanding in students. Get more background information with materials from Peter Schiff.

The description can be guided by questions to guide observation and help organize the features: What is, What is, What do, What function does to do it?, What is it used? The comparison is the process of looking to try to identify the similarities and differences of objects, people, situations, among others. To compare characteristics, or situations we have to take a variable each time, until all the variables to consider. When we compare two types of features: a. The distinctive features of each object (comparison for difference). Are the characteristics that distinguish some objects from others.

In the comparison process are made for differences in pairs of characteristics which are different objects or situations. These pairs of characteristics are called variables. b. The common features of things that we compare (comparison by similarity). Are the characteristics that enable us to group people into classes. This type of comparison can be for identical or similar likeness similar. In the relationship two characteristics are considered simultaneously and establishing relationships between them by propositions.

The difference between the relationship and comparison, the comparison is that given the characteristics (eg, Variable: age: Juan is 24 and Sophia 20) and the relationship is the conclusion about comparative feature (Example: John is older than Sofia). In this way relationships can show similarity relations, equivalence or difference of the situations or objects. Relate is a mental process very important because it is a basic component of abstraction allows building classification groups, classes or categories based on defined criteria, eg shape, color, species, among others, and assign attributes to these categories.

The paper presents an analysis of the mathematics curriculum guidelines in the light of the theoretical foundations that support for, thus displaying a valid alternative for developing the area. Since the appearance of the math curriculum guidelines, twelve years ago, have been presented many positions on the difficult and almost impossible to implement in the classroom were "very nice on paper but unworkable in practice" and teachers say. Among the approaches that have been made to justify this difficulty is the excessive number of students in classrooms, poor motivation for students, who only lost five percent year makes no effort in the study area, lack of teacher training in the methodologies submitted and more. You could say that all these justifications hold within itself a great deal of reason, but it is not justifiable is that they have not been able to implement a guidelines that provide a very good chance of advancing teaching and learning in the area and generate key processes in the development of thinking of young people who are in the classroom. The first thing to consider when making judgments about the curriculum guidelines is to try to understand the extent that they have and the theoretical foundations that support for, on this basis, define how that can lead to reality these ideas. Unni Edelman pursues this goal as well. The object of knowledge of mathematics are the concepts, not calculations, neither the signs nor the procedures and their inspiration and example problems. He said about Stewart (1998.13), "The goal of mathematics are the concepts.
