Scientific objectivity‚ according to Louise Antony and Thomas Kuhn‚ is fundamentally unattainable because of the human epistemological condition. The open-mindedness‚ or freedom from existing notions‚ that pervades almost all definitions of “objectivity” is inherently uncharacteristic of the human mind‚ and Antony explains that scientific reluctance to entertain new‚ controversial hypotheses is one manifestation of this innate mental road-block. When scientists view data that contradicts the central

Negative Commercial Influences on Scientific Research In the past over 20 years‚ the pace of innovation is accelerating. Links between science‚ technology and business are numerous. It is no secret that these links are increasing in number and extent. Both governments and business assert that this close relationship is generally positive for science and technology on the one hand and society on the other. However‚ there is growing evidence that this relationship brings with it a range of detrimental

Throughout the story “The Repairman‚” several scientific devices of varying accuracy are presented. The author describes and uses some that use plausible science‚ but the facts and possibilities of each are not important to the story as a whole. The varying devices are described just enough to propel interest in the story‚ but most of the actual scientific plausibility has to be inferred from context. In the story‚ hyperspace travel is presented in a way that explains itself to a degree‚ but in

The Research Method Case Scenario A. The research scenario question I choose that could be studied using the scientific method is question 1: How much do reading scores change from the beginning of the school year to the end of the school year? “Scientific method is an approach to knowledge that relies on collecting data‚ generating a theory to explain the data‚ producing testable hypotheses based on the theory‚ and testing those hypotheses empirically” (Morris & Maistro‚ 2012‚ pg 8).

3/22/2013 Lab 1- The scientific method In this lab I am learning about the steps of the scientific method and how it can be applied to daily life. In my first exercise I analyzed data presented to me in a table (table 2) on fish population in relation to the amount of dissolved oxygen ( ppm ) in the water. The patterns indicate that when more dissolved oxygen (ppm) is present in the water‚ the number of fish observed increases. In developing a hypothesis for this theory‚ I have decided that if

Scientific Revolution and Enlightenment in Europe With the emergence of the scientific revolution in Europe in the 16th and 17th centuries‚ modern sciences like physics‚ mathematics‚ astronomy‚ biology and chemistry transformed the view of the society and its nature. Advances in scientific thought brought about changes in the way man perceived and made sense of his surroundings‚ thereby fostering immense changes in traditional beliefs and thought systems‚ and more so in religion. From the advent

What is meant by the term scientific benefit? Scientific benefits are the benefits in terms of knowledge and understanding gained from scientific research which provides explanations of and explanations for complex phenomenon and behaviour. This can be applied to real life in the form of treatments or such‚ for example Robertson and Robertson’s study provided scientific benefit in that it was discovered how important a child’s attachment to their Mother is. Using psychological knowledge and research
