This thinker was a great astronomer, that is to say a man I practice, a scientist. Astronomy is a elevadamente worthy science. The denominated science of the stars, which studies the movements and the laws govern that them. We know great astronomical discoveries which were done by the Babylonians, and later by Chinese and the Egyptians. And especially by Such of Mileto, anaximandro and Pitgoras (S.I SAW AC) Aristotle and Aristarch de Samos (S IV AC), Tolomeo (S II DC) already in the century (XVI) Copernico who I affirm that the sun was the fixed center of the planetary system. In this route we found eminent astronomers, among them: Tycho, Brahe, Galileo, Newton, Kant, Laplace, Herschel. Which reflect in their theories a powerful Philosophical influence.
The physics and the philosophy own a so quiet relation that little it is perceived. This relation is originated in the primary elements of the scientific causes. Obsrvese that whenever we went to the experimental phase, we tried at all costs possible to reduce the perceptions of brings back to consciousness abstract, with the purpose of to elaborate a quantitative determinant of the material spheres that we analyzed actually. The deductions that form the universal representations of the abstract ones are reduced by mathematical and Metaphysical phases. Young person whoever who you are, escudria the lessons of your educational ones. And you do not allow that the fleeting things of life separates to you from your dreams.
Brndale to the society an excellent academic level, that your educational ones feel proud of you. It remembers that teaching is of the workings but worthy that they exist on the Earth face, you do not have in little to exerts those who it, Refutes the theories of your educational ones, as long as you make with respect and knowledge of cause. It evaluates your parents and you do not think that all your time belongs to him to the study, the geniuses do not form of extremist ways, contribyele to your society but first of all you are not mediocre.
Topic has naming: the work is replaced by electric motor muscles. It would like to tell about this new and innovative development of scientists, as an artificial electrical muscle. Those who are familiar with electrician and the basics of electricity, is well aware of the basic ways of converting electrical energy into mechanical motion. This is, first of all, electric motors of various types, principles of operation, type of power, etc. They have, by passing electric current through the inner windings, formed the electromagnetic fields to repel each other, thereby causing the rotation of moving parts. Such movements have rotational in nature, which often requires additional mechanisms for the conversion of translational. At the same time lost some of the energy, increasing energy costs.
Even the motors because of their construction and operating principle of efficiency is not ideal. There is another way to make forward movements by means of the same magnetic field. This is a retraction or repulsion in the electromagnet core. Disadvantages is also not ideal efficiency and the difficulty of a precise control of the action. Now let's see what can be replaced by an electromagnet and electric motor work in our time. This is an analogue human muscle, which runs on the same principle. As you should know from the lessons of biology, upon the momentum of the human nervous system to its muscles, there is a reduction of protein fibers. This eventually leads to simple muscle contractions (reduced length) and carry out some physical work.
This principle is very simple. But due to the fact that scientists are a long time could not create such an artificial material that would repeat the work of human muscles, this idea was in place and had no further development. In 2007, scientists from the University of North Carolina, announced that they have managed to create such an electrically conductive polymer on based on carbon nanotubes.
The level of mathematical knowledge that a student receives, directly depends on the skill of the teacher. Professional teacher, who is also very actively studying math, it is easy to find a common language with the pupil. Study the subject will turn into an interesting process where both parties are actively involved. Of course, the student with the teacher need fear no exams – and it is easy to pass the cse in mathematics, and centralized testing. But what if your high school teacher has been very weak? There is a way: You can organize extra classes, you can invite a tutor. But to such additional steps have brought maximum benefit, remember the simple rules described in this article. Errors – this normalnoIzbegayte overly harsh penalties for a wrong decision. Otherwise the student will be unable to perform even the simplest task for fear of making a mistake.
In such situations, children tend to "hack" stuff – sometimes literally, as it is written in a textbook. " The quality of knowledge in this case is substantially reduced, the new material poorly understood and, therefore, further study of mathematics is difficult. Focus on the achievements of the child, rather than its problems. Let the right decision task will be an occasion for joy. A complexity – it's one more reason to act, an occasion to try to find a solution. Encourage the "how" and "Why?" Always have a situation where the teacher after explaining the new material asks the question: "You all right? Any questions? "Usually in response to the class is silent.
