As you may already know, scientific knowledge is extremely necessary for the evolution and development of human beings and the society we know. This is because scientific knowledge promotes the creation of increasingly efficient technologies that improve our lives in several aspects. In addition, it allows several phenomena that happen in the universe to be explained in a coherent way and with scientific data. All of this is accomplished through research managed by scientists. These scientists need to have some characteristics for scientific knowledge to be established. Among these characteristics we can mention a curious, questioning and rational nature.
