For this session, we started by discussing the characteristics of scientific observations and experimentation, on the other hand, we conversed on the place of theories and models in science and society. We started the discussion with a little historical knowledge, learning about the Greek philosophers, Plato (429 -347 BC) and Aristotle (384 -322 BC), considered scientists dating back to the 5th century BC.

Get an original essay Plato and Aristotle were two of the most influential philosophers in history and, Aristotle was in fact a student of Plato, Aristotle who was influenced by Plato, managed to find many flaws in Plato's theories which pushed him to criticize most of the work of Plato. However, both philosophers based their theories on the same four widely accepted beliefs; that knowledge must be about what is real, the world experienced through the senses is what is real, knowledge must be about what is fixed and immutable/immutable, and the world experienced through the senses is not fixed and immutable/immutable. Aristotle was the first to understand the importance of empiricism, which is knowledge derived from investigation, observation and experimentation and which can be verified. Continuing the lesson, we discussed the role of observation, which is not only an integral part of any scientific experiment, but is also the central element of the scientific method, therefore, to improve the observation process, some tools were invented, for example example microscope, cameras, etc. There was a little debate between quantitative and qualitative to see which we believed was best. In my opinion, the quantity would be the best of both, but it would depend on the situation or context in which it was used. We moved on to the topic of experimentation which was defined as a test or trial that produces evidence that can be used to test a hypothesis. We looked at a famous scientist, one who discovered and was able to completely describe the circulatory system in the body, William Harvey (1578-1657), considered a pioneer of modern embryology. Harvey studied blood flow from veins to arteries, through the heart and lungs, as well as showing valves in the veins. This topic was very exciting for me because as a child I always wondered how the body worked. A controversial topic we discussed then was the difference between theory and law, while a theory would be defined as a general statement that would correctly explain all experimental observations on such behavior and properties of a wide variety of objects and a scientific law would be defined as a statement of fact and are expected to be true, meaning that the same result would occur. I had the opportunity to learn about Newton's theory of universal gravitation. Please note: this is just an example. Get a custom article from our expert writers now.
