Luminous Intensity › Definition and Meaning
The phenomenon of light from the viewpoint of its measurement is studied in the discipline known as photometry. In this framework, the light intensity indicates the amount of light that is perceived (the scientific term used is the luminous flux).From a mathematical parameter, the light intensity is something that can be measured, for which the unit known as candela used. In this sense, remember that light has different measurement units (lumen, lux, lumen per watt and others) and each used to measure some aspect of light. Not to forget that light is a form of energy, particularly electromagnetic energy.
The light intensity in different areas
The apparatus used to measure the light intensity is the light meter, which operates using a sensor that detects changes in light intensity. The light meter can record a series of data, which refer to the measurement of light in a given space. Such measurements are necessary to determine if the light used is appropriate. For example, in a classroom light intensity at different points (on the board in the location of the teacher and in the area for students) it should be established, since it would make sense that a place in the classroom was in penumbra while another space had a significant presence of light.The example of the light intensity in the classroom allows us to remember that the presence of light is decisive in all kinds of activities. Think of a covered sports arena where spectators and athletes need adequate visibility. In this case, the light intensity determines the development of any activity undertaken in that space.
Decorators know that the light intensity is a staple, it has effects on the colors on the self - perception of space or in connection with personal feelings that occur in a particular location. The role of lighting in the decor is first order. Normally you try to make the most of natural light and artificial light is a secondary option. Naturally, the interior space artificial light has a role. Thus, the light intensity affects many different ways: creating a climate specific, providing an optical effect or serving a specific purpose. In any case, the light intensity must be associated with a particular function in each case.
In the world of decoration speaking of the language of light. If intense energy is transmitted. If excessive is very likely that an effect of fatigue occurs. And if the light is warm is quite possible that a relaxation effect is created.

Belie that is related to birth defects, allergies, tumors and, generally, with any health problems to humans or animals. To prove it is a safe product recalls in Europe it is widely used in public gardens and private sphere.Moreover, transgenic companies argue that there is no relationship between agrochemicals (such as glyphosate) and transgenic products.
Against glyphosate
The reviews are very diverse and are based on a number of arguments. Alternative Scientific studies demonstrating a causal link between glyphosate and a range of health problems (related to autism, Parkinson's, obesity, allergies, cancer, etc.). It is considered that there is a close relationship between glyphosate and genetically modified products. Moreover, some groups claim that at present there is a global experiment to impose the use of this herbicide. While glyphosate should be labeled, products related to it are not, which raises suspicions and fears.conclusion
The two opposing positions highlight the existence of two concepts: 1) those who accept the official information as necessarily true and 2) those who understand that behind the glyphosate perverse economic interests hiding and is being put into danger the health of millions of people around the world.The two opposing views remind us that there is another similar dilemma: those who understand climate change as a natural phenomenon against those who attribute it to human action. When two visions are so opposed and irreconcilable citizens it is at a crossroads of difficult solution.
