Resumo - Scientific methods

    Since the origins of time, humans have thought how things were created. They made questions about them and found aswers, making new developments; building the science. Science studies the physical world. It has branches, like astronomy, botany, geology and zoology. However, each branch has its characteristics in the use of scientific methods. The method that scientists use allows them to collect and process information efficiently. Thales of Miletus tried to organize the knowledge of physical world. He studied the constellation, the sky, earthquakes and solar eclipses.
    To make a scientific method, the first thing to do is observate, as Thales did. Next step is to create a hypothesis, as Lucretius invented his one to write "The nature of things". But, just observating and coming up with a hypothesis isn't enough. There must be an evidence, as Newton found his discoverie. Using these steps, scientists learn more and make new discoveries about humanity.
