PowerPoint PresentationSlide 2What is a Scientist?Who and What is Your Instructor?Big Problem:Let me illustrate this problemInformation Overload!How Much Info is There?Slide 9Slide 10How Does a Science Teacher Present a subject Given Such a Vast Amount of Information?Pledge: I will make every effort to present a balanced or at least both sides of a controversial arena in science, biology, ecology and the environment. But like every person, I am operating from a certain ‘worldview’ and I believe that you need to know what that worldview is. There is no such thing as “valueless teaching.”Slide 13What do I expect of You?Slide 15Lecture 1 Goals:Slide 17Operational ScienceSlide 19Scientific Reasoning (Propositional Logic)TermsSlide 22Example of InductionProblems with InductivismSlide 25Slide 26Example of DeductionDeductive ScienceExampleSlide 30DeductionHypothetico-Deductive MethodPrinciple of DeductionSlide 34Deductive Falsification (Conjectures and Refutations)Slide 36Example of Falsification from InductionProblems with FalsificationJudging H0’sSlide 40Science ValuesSlide 42Objectivism and Subjectivism result in at least three concurrent views of science…1- Scientific ImperialismScientific Imperialsim2- Postmodern RelativismSlide 473- GodismsApproximate Proportions of US population holding the 3 general philosophical views of Scientific InformationSlide 50Science: Research programsSlide 52Slide 53Slide 54Assignment: Learn the Presuppositions of ScienceLecture 1 Science: What is it wrap-upSlide 57Now playing: Mike and the Mechanics, “All I need is a Miracle”Lecture 1.1IntroductionLecture 1.1IntroductionWhom and what is your instructor?Whom and what is your instructor?Applied EcologistApplied Ecologist-Researcher?-Researcher?-Teacher?-Teacher?-Science & Agricultural PolicyExpert?-Science & Agricultural PolicyExpert?-Family Man-Family Man -Ph.D = Doctor of Philosophy,therefore, a philosopher? -Ph.D = Doctor of Philosophy,therefore, a philosopher?What is a Scientist?What is a Scientist?•publish scientific papers•belong to a scientific society •are married to, a nonscientist •watch news, documentaries, and movies on TV •spend 52 hours per week working •have an affiliation to an organized religion •play a musical instrument •spent 4.9 years in postdoc positions •travel to at least one scientific meeting per year •prepare a meal at home at least once per week •spend 10 hours per week lecturing and mentoring students •read fiction and nonfiction books •participate in sporting or athletic activities more than once per week •have lived in another country •watch a movie more than once per week, with comedies being the most popular genre •are motivated by innate curiosity •vote in national elections •spend at least one hour per day on the WebMore than 50% of the readers (The Scientist ) who responded to our surveys ...Who and What is Your Instructor?•Ph.D. = Doctor of Philosophy, therefore, a philosopher?•Research Scientist?•Life Science Teacher?•All Science??Big Problem:Big Problem:•What to teach?•How much to teach?Every teacher has a …Every teacher has a …Let me illustrate this problemLet me illustrate this problemEducation:BA- Pre-Med Biology, minor-Chemistry Trinity College, Deerfield, ILBioprocess Development- Abbott Laboratories, North Chicago, ILPh.D.- Cell and Molecular Biology-Microbiology, Michigan State UniversityInformation Overload!Information Overload!•I have over 125 credit hours of science classesI have over 125 credit hours of science classes•I have read a couple dozen science text booksI have read a couple dozen science text books•I have read about 1800 research papersI have read about 1800 research papers–3562 in my reference manager3562 in my reference manager–Only 230 in my thesisOnly 230 in my thesis•I go to scientific seminars >5x more than I go to the I go to scientific seminars >5x more than I go to the video store.video store. •I am familiar with less than 0.0000001 of the published I am familiar with less than 0.0000001 of the published scientific literature!scientific literature!How Much Info is There?How Much Info is There?•Michigan State’s Library (est.1955)Michigan State’s Library (est.1955)•Main library and 14 branchesMain library and 14 branches•4,000,000 volumes 4,000,000 volumes •28,000 serial subscriptions (in print and 28,000 serial subscriptions (in print and electronic form) electronic form) •5,000,000 items in microfilm and microfiche 5,000,000 items in microfilm and microfiche •200,000 maps 200,000 maps •40,000 sound recordings40,000 sound recordings That’s Nothing!That’s Nothing!In 1814 the entire collection was 3,000 books.
