Phlogiston theory

Phlogiston theory The phlogiston theory states that the every combustible substance on this planet contains phlogiston. When a combustible substance is burned, phlogiston is released into the air. The people behind the phlogiston theory believed that the whenever a substance sets on fire, the fire gives off phlogiston. The phlogiston was believed be the kind of gas which causes fire. Without phlogiston, the combustible substance won’t be able to set on fire. In the late 1660’s a scientist named as Johann Joachim Becher tried to explain the phlogiston theory. He thought that the every substance which is present on this planet has a different kind of earth. For each earth substance…

philosophical and scientific problem that has been debated since ancient Greece. The pursuit of discerning between the way things are and the way they appear to be is one driven by the human desire to understand. Appearances can mask reality and skew one’s perception of reality. A group of early Greek philosophers and teachers, known as the Sophists, proposed that reality did not exist, and if it did, it was beyond human comprehension. They believed in relativism and sought to solve practical…

accurate, so it’s the investigators job to be able to discover out what information given is actually valuable. One of the most important and reliable way to find information is through physical evidence, whether its blood, fingerprints, or even remains. This ties in with the scientific method because once the evidence is found, forensics comes into play to find out whose blood, fingerprints or remains belonged too. Even though records can be a form of physical evidence, it can be seen in a…

this observational study is to gain perspective of the various theories of development that were taught in class. Also, to help the observer understand that observational research is complex and difficult to describe a five-year-old female child objectively. The observation took place in the child’s home for one hour while her parents were present during the study thus, the mother can sign the permission slip. Descriptive information The child observed was 5 years old named Kerly Lopez, she is…

but broadly explaining what Instrumentalism is, but it should first be noted that there are multiple types of instrumentalism. Instrumentalism is a: “broad pragmatist attitude towards ideas or concepts in general, the distinctive application of that label within the philosophy of science is to positions that regard scientific theories not as literal and/or accurate descriptions of the natural world, but instead as mere tools “ or ‘instruments’ for making empirical predictions and achieving…

Based on the observation, the inquirers craft a hypothesis to explain their views. Ideally, a scientific experiment tests the hypothesis to try to control the results of experimental variables; there is only a single element in a time of change in the case of the experiment so that the results will be based on the effect of this single variable that can be measured or otherwise observed. And analysis of experimental results show that the null hypothesis may be mistaken, and thus, in this case,…

Two theories which were believed in previous time periods were the Hippocratic theories and the theory of ovist preformationism. The Preformation’s and Hippocratic theories were used in the late seventeenth to early eighteenth centuries to explain how organisms develop from embryos as well as how characteristics are transferred from parent to offspring. Both theories explained these mechanisms partially correct with some explanations still see to be true today. On the other hand both theories…

In this paper, I will examine Brenda Medina’s story known as Hell and How I Got Here through a criminological angle. I shall summarize Medina’s story, present a simplistic format of the theories I believe were in play in her story, and then connect those theories with her story. Additionally, I want to note that I will only disclose the theories that I consider to have been the most prominent in Medina’s story, since, there is a large number of theories that can rationalize what happened; but…

scientists use their sense perception in order to create their theory. Researchers use inductive reasoning to "make generalizations from specific observations." (Staff, Live Science. "Deductive Reasoning vs. Inductive Reasoning." LiveScience. TechMedia Network, 10 July 2012. Web. 4 Mar. 2015.). Inductive reasoning also allows for the researcher or scientists to create hypothesis or theories based on their senses (such as sight, hearing, or touch). An example of a scientist using passive…

relationship between theories and the world to which theories meant to apply? Are there ultimate truth which can be obtained through a series of scientific validation and falsification? Is critical relativism appropriate for scientific research (marketing or consumer research in particular)? Those are some critical questions raised by this week’s readings that centered on the topic of rationality and relativism. Several authors provide different insights on answering those above questions as…
