Ótica e a visão humana

Optics consists in the study of interaction of light with physical systems. The human vision is a product of the interaction of light with the eye (a very peculiar physical system). Here we present a basic study of the relationship between the optics and human vision, including: - The fundaments and physicals properties who characterize the light and the colors and the characteristics of the incidence mediums. - The basics laws of geometrical optics, based in the rectilinear propagation of light in the form of a light ray, in the independence of light rays and in the principle of reversibility of the light beams. This principle is present in the process of image formations in lenses and mirrors and applied in the study of image formation in the human eye. - The refraction and reflection laws and types of lenses, who permits the construction of optics devices for the study of physical universe, and the appliances to correct vision diseases. - Presents the human vision process as consisting in the reception of light (electromagnetic radiation in the zone of wavelength visible to us) through the eye and the sending of information obtained by the retina to the brain where it is interpreted. The vision involves a biophysical relation between the light and the biological structure of the eye who is constituted by cornea, iris, crystalline and retina. Analyzes is made of how some parts of the eye performs a function in the reception and sending of information of the images to the brain

As decisões de investimento e a instabilidade financeira

Initially, the text handles the theories of ancient classical and changes with the emerging of the debates of the schools of economic of Keynes and Kalecki. Over the years, from 1930 onwards, investment theories were debated and modified by various schools of economic thought. One of the debates that stands out in this work are the theories of Minsky that will bring new reformulations to Keynesian theory and a greater focus on psychological factors as determinants of investment decisions. Through financial instability hypothesis Minsky explains how the decisions to invest and the access to credit cause instability to financial system. Finally the work will show how access to credit is material when companies decide to invest and how these investments are often handled due to information asymmetries in the market. The financial institutions seek to maximize their profits while dribbling moral hazard and adverse selection, and thus the government needs to intervene once in a while as a regulator to maintain the solvency of the system
