What constitutes proof? How has evidence and truth evolved/changed as society has progressed? Use examples to illustrate how the truth can be questioned as new ideas arise. Evidence is fundamental in science. It plays a role in proving the hypothesis. But what can be a piece of evidence? Aside from this, some “truths” or evidence once accepted by the world may be changed as society advances. The evolution of truth and evidence can be driven by a variety of factors. In this essay, part one will focus on what is considered evidence in science, how evidence and truth have changed following the paradigm shift cycle, and illustrate the factors that have caused the truth to be contested with different examples. to prove a statement. Scientific evidence will be focused on this trial. Scientific evidence can be used to support or reject the scientific hypothesis. Evidence is often found by different scientific methods. Based on various scientific methods, scientific evidence can be mainly divided into two types: observational evidence and experimental evidence. Observational evidence plays an important role in scientific discovery. This type of evidence is produced by perceptual sensations like hearing, seeing, touching, smelling, and tasting, with the help of certain instruments like the microscope, telescope, and stethoscope (Bogen, 2009). The most common example of using observational evidence may be when Galileo used the telescope to observe the four satellites of Jupiter in 1610. This may be a piece of observational evidence in astronomy. In medicine, observational study means that researchers obtain evidence by observing the condition of the exposed patient...... middle of article ......omas S. (1957). The Copernican Revolution.
