FILMS

At the moment, there are different options to do in the free time, for example watch a film: some people prefer to watch films at home, while other people prefer to go to the cinema, both options are good, but I will compare find the really differences: advantages and disadvantages.

Firstly, currently the technology gives us the possibility of buying a home theatre that of simulating a cinema, the sound and the video are very similar to cinema, that is why this reason that some people prefer to watch films at home, the two options are the families plan, then it is an important similarity because we are in family.

On the other hand, the economic difference is relevant, at home you do not spend money while that the cinema you should buy tickets and food, then the option to go to cinema is more expensive than to watch a film at home, but in some times is better to go to cinema, because despite paying be in a different place, services and things you change the environment.


In summary, but options are good, depending on the objective, choose the best options, you should remember some aspects: money, environment, free time and the family.

The low quality of the education in Colombia

Nowadays the education plays an important role in the formation of each one of the persons, nevertheless we see that the education is not taken by the importance that is deserved, but on the contrary it is an aspect to the one that does not give itself the necessary attention, it is for this that Colombia appears in the last three positions between 57 countries and with a puntaje very lower than that of the first one, Finland. A time ago, in an international test of the same type, Colombia had occupied the position 44 between 45. These numbers do a severe question to the educational Colombian model.

The global information shows that the most developed countries and with better distribution of money they have the highest results, the slow advance of Colombia in distribution of the money, The unequal distribution of the revenue and of opportunities reduces the educational quality, you cause for which one presents the low quality of the education in colombia.


Other one of the big faults of the educational system is that from the Cologne it has predominated over the belief of which the qualit education must center in a privileged sector, at present, the presence of the students of strata 5 and 6 is practically Void in the public schools. These students prefer to lose the subsidy and study in private schools where they pay highly costly pensions; The same thing happens with the executives of the colleges, which there prefer the students of high strata who pay major matriculations and can be formed by minor efforts.

Finally is confirmed the theory of which the principal determinants of the school performance are the cultural tradition, the distribution of money and the environment; The solution of the educational quality is in an integrated system, in which the students of different strata are present at the same schools. In general terms, it considers to strengthen the public education, to create the conditions of location and transport in order that the students of different strata could go to the same classrooms and open the possibility of giving scholarships that 1 and 2 assure a minimal presence of the strata.

Resonant magnetic Imaging MRI and Food Preservation Processes,



Along the years they have left discovering and creating new inventions that have been useful to the society and that they also have from all over the world changing the life of people, some of the big discoveries are: resonant magnetic Imaging MRI and Food Preservation Processes, discovered for: Paul Lauterbur, Peter Mansfield and Lloyd Augustus Hall.

Paul C Lauterbur and Peter Mansfield was the inventors of resonant magnetic Imaging MRI, while Paul C Lauterbur was located in New York, in the state university as ` chemistry professor, Peter Mansfield was in Nottingham, England, Paul wrote to paper on to new imaging technique which has termed zeugmatography (from the Greek zeugmo meaning yoke or to joining together). Lauterbur imaging experiments moves science from the it sails dimension of NMR spectroscopy to the second dimension of spatial orientation - the foundation of MRI. While further developed the utilization of gradients in the magnetic field. There is showed how the signals could be mathematically analyzed, which made it possible to develop to useful imaging technique. Peter Mansfield also showed how extremely fast imaging could be achievable. This grants a scholarship me technically possible within medicine to decade later. Being these two investigations what you/they would take to the creation of a team of great help for the doctors, the illnesses and the community.


On the other hand, An industrial food chemist, Lloyd Augustus Hall revolutionized the meatpacking industry with his development of curing salts for the processing and reserving of meats. There is developed to technique of "flash-driving" (evaporating) and to technique of sterilization with ethylene oxidizes which is still used by medical professionals today.


Finally, we see that the famous inventors before mentioned they have created or discovered inventions that have been from an or another way contributions to the medicine and the same society, as well as there are differences among their location and perhaps the time, these they have been able to leave a base for future creations.

INVENTORS OF RADIO AND TV

When we do comparison we find differences and similarities with regard to the aspects and spoken topics, the case of the inventors is not the exception, each of the differences are a relevant part of the careers, Guglielmo Marconi and Paul Nipkow They are some examples of the famous inventors, they were those who invented the radius and the television respectively.Firstly, Guglielmo Marconi, demonstrated the viability of communication of radio. He sent and received his first sign of radio in Italy in 1895,while Paul Nipkow developed a technology of disc of draft to transmit pictures on the cable in 1884 called the disc Nipkow, the anuses of the first tests were different, but these inventors were the first ones in discovering these inventions.In other place, Nipkow's system was left early in TV's history for the electronic systems developed by posterior inventors, while Guglielmo in 1899 he directed the first wireless sign across English Channel and two years later it received the letter "S", cabled of England to the Newfoundland. This was the first message of guessed right transatlantic radiotelegraph in 1902 and This was the first system of exploration of electromechanical TV himself.Finally, these two inventors gave significant contributions, the discoveries of them were the base for the today technology, even if Nipkow desert of the discovery his beginnings were very important for the posterior inventors.

PHONE AND CELLULAR

The communications are an important part nowadays in the society through that we live, inventions like the telephone and the cellular form a part of each of the habitants of certain community, it( is because of it that is interesting to know about its inventors: Antonio Meucci (creator of the telephone) and Dr. Martin Cooper (inventor of the cellular one)Martin Cooper born in Chicago, Illinois is considered the father of the mobile phone. Cooper is the CEO and founder of ArrayComm, a company that works on researching smart antenna technology and improving wireless networks, and was the corporate director of Research and Development for Motorola , Antonio Meucci was born in 1808 and studied design and mechanical engineering in the academy of Florencia's fine arts. Meucci I design a primitivedevice in order that the communication was easier in the Theatre della Pergola.In other hand, Bell Laboratories, introduced the idea of cellular communications in 1947. But Motorola and Bell Labs in the sixties and early seventies were in a race to incorporate the technology into portable devices. Cooper, now 70, wanted people to be able to carry their phones with them anywhere. While he was a project manager at Motorola in 1973, Cooper set up a base station in New York with the first working prototype of a cellular telephone, the Motorola Dyna-Tac. After some initial testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public. But, on the contrary, Meucci did not have so good luck as Cooper, In the decade of 30s transfer to Cuba to deepen its knowledge in treatments to calm ailments with electrical shocks and was there where it discovered the possibilities of transmitting sounds through copper cables. Thinking about the potential of this new discovery, about 1850 transfer to Staten Island near New York to be developed and to perfect this technology. In 1860 his invention it was published in a newspaper for the Italian community that already circulated in New York and for 1862 tapeworm but of thirty models of his €œteletrofono€? and it had installed in his house, ensure communications with his wife who suffered of arthritis and hardly she could move. With the purpose of to collect money for materials, Meucci sold its prototypes to $6 dollars. But it was not possible to secure $250 dollars to him to patent his €œTelégrafo Parlante€. The unique thing that could do with the money that it had, was to leave a notification of renewable pending patent to a year and sadly three years later, it did not secure $10 dollars to renew it.finally, we see that these two inventors had great ideas but to one of them by the lack of money the recognitions were not made him in time, years later was that the necessary accreditation occurred.

INVENTION: Invention or invention is an object, technique or process which own novel characteristics. It can be based on some idea, collaboration or previous innovation and the process of the same at least requires the knowledge of a concept or existing method that can be modified or be transformed into a new invention. Nevertheless, some inventions also represent an innovating creation without antecedents in the science or the technology that extends the limits of the human knowledge. Sometimes legal protection to an invention by means of a patent can be granted.

INVENTOR: The word " inventor" it comes from the Latin verb invenire, invent-, to find. (To see the section creative personality in the Inventive article). The phrase " the necessity is the mother of invención" , it discusses essentially that, the deficiency of resources leads to the invention, whereas a school of the opposite thought argues that only with an excess of resources these results are obtained. Nevertheless, at the moment the inventive process by the reference to one of them cannot be understood simply of these perspective. In general terms although the inventiveness usually responds to a necessity, it is not dismissable that from a rich atmosphere in resources new experiences arise that generate inventions.

SCIENCE: The science (of the Latin scientia ' conocimiento') it is the systematized, elaborated knowledge by means of observations, reasonings and tests methodically organized. Science is worth of different methods and techniques for the acquisition and organization of knowledge on the structure of a set of facts accessible objectives and from several observers. The application of those methods and knowledge leads to the generation of more objective knowledge in the form of concrete, quantitative and provable predictions referred to observable facts pasts, presents and futures. Frequently those predictions can be formulated by means of reasonings and structure like rules or universal laws, that give account of the behavior of a system and predict how this system in certain circumstances will act.
