TOK Essay 4. “That which is accepted as knowledge today is sometimes discarded tomorrow.” Consider knowledge issues raised by this statement in two areas of knowledge. Knowledge is formed from different ways of knowing‚ with different language‚ perception‚ reason and emotion‚ a same issue can be interpreted differently by different person or group. From a personal level perspective‚ due to the difference in their background‚ culture and experience etc‚ a person’s knowledge is often different with

Fawzi Abdelgani Ahmad . Experiment 1: Experimental Uncertainty (Error) and Data Analysis Jan/30/2013 PRELAB: 1. Do experimental measurements give the rule value of a physical quantity? Explain. No. Statistical methods are used to establish the deviations in the measurement. 2. Distinguish between random (statistical) error and systematic error‚ and give an example of each. Random errors are caused by unknown and unpredictable changes in the experiment like mechanical

To determine the heating and cooling curve of water Design: What we are going to do is investigate the phase changes and what the heating curve of water is. We are going to do this is by heating up 100ml of water on a Bunsen burner then adding ice cubes. Use a thermometer to measure the temperature every 30 seconds until it reaches a plateau. Hypothesis: As more time passes‚ the temperature of the water increases. Independent variable: Time Dependent variable: Changing water temperature

Some of her 3 major achievements were that she and her husband won a Nobel Prize‚ She discovered 2 new elements‚ and the first forms of cancer treatment using radiation. Marie and her husband‚ Pierre‚ won a Nobel Prize in physics in 1903. In the book it says‚”Although 1903 was only the third year the awards were made‚ they were already regarded as a great honor….With their award‚ Becquerel and the Curies were immediately identified as three of the world’s greatest scientists

He also developed the three laws of motion. These laws are what have formed modern physics. Newton also worked in optics where he studied white light and discovered the color spectrum. These experiments with light were what first made him famous. Newton may have been well known for his work in gravity and light but he made many other

The Influence of Science Today Science: “the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.” (Dictionary.com). New things are discovered each day of the year. Some of these discoveries are small‚ and some are major things that affect how people live today. Sir Isaac Newton was a scientists who influenced scientists today. Because of his influence on society‚ his discoveries

Have you ever considered the possibility that the fundamental makeup of our universe is something completely different from what science has led us to believe? Perhaps our world isn’t made up of protons‚ electrons‚ atoms‚ and molecules‚ and that all of our theories of quantum mechanics and macro/microphysics turn out to be incorrect. Perhaps we were created for a greater (or smaller) purpose than we are aware of. How would you react if you were to learn that our universe is nothing as we thought
