  1. 2103-390 ME Exp and Lab I • Knowledge Why Knowledge? Is knowledge useful? Example 1: I “know” that I can fly, so I jump off the third floor of Engineering Building 3 and flap my limbs. Example 2: I know that things fall down, so I try not to drop my glass.

  2. Question: What is (propositional) knowledge? Question: What is (propositional) knowledge? Activity: Class Discussion Who cares?

  3. Knowledge: JTB Model Some guys say that there are 3 necessary conditions Justified True Belief but they are not sufficient. Some terminology used in logic 1. Justification 2. Truth 3. Belief

  4. Why Justification? • Why Truth? • Why Belief? Is our belief justified? to an extent such that we can appropriately make decision and act on it (and accept the consequence)

  5. Question of Question: How can we find out …?

  6. Question of Question: How can we find out …? Question: How much is g in m/s2? Question of Question: How can we find out how much g is in m/s2?

  7. Question: How much is a drag force on a car moving at 140 km/h? Question of Question: How can we find out how much a drag force on a car moving at 140 km/h is? Activity: Class Discussion

  8. Guide for The Course (Propositional) Knowledge: • Knowledge is a statement(about something) • that we have a reasonable justification • to believe that it is reasonably true. Justification = Justification Method + Supporting Evidence

  9. Guide for Experiment There must be a reasonable justification (justification method= appropriate experimental method and/or justifying theory +supporting evidence= experimental evidence/data) to support a claim of a statement (= statement:experimental-results/conclusions) as being “reasonably true” before a claim statement can be considered/accepted as provisional knowledge (= statement:experimental-results/conclusions).

  10. Brief Structure of An Experiment

  11. Some Qualifiers in Experimentation Observation - Ask the Right Question / Critical Thinking / Creativity 4) Clear, Concise, and Convincing/Justified Conclusions 3) ConvincingSupporting Evidences / Experimental Results 2) ConvincingJustification Method 1) Clear and ConciseProblem Statement / Question 5C = Clear, Convincing, Coherent, Concise, and Consistent

  12. Report: Conclusions What are conclusions? Conclusions are convictions based on evidence. From The American Institute of Physics: AIP Style Manual, Fourth Edition: http://www.aip.org/pubservs/style/4thed/toc.html
