TRANSCRIPT

  • New Core CurriculumFoundations of Scientific ProcessTheories and Scientific LawsScience vs. Pseudoscienceweek 2, class-1

  • Science is concerned with investigating and making sense out of the environment and trying to predict future observations.What ? Where ? How ? Why ? Movie Contact http://www.youtube.com/watch?v=SRoj3jK37Vc

  • Theory & Scientific LawTheory is defined as a broad, working hypothesis that is based on extensive experimental evidenceex. Plate Tectonics Theoryhttp://en.wikipedia.org/wiki/Plate_tectonicsWhen theory is around for a long time it is sometimes promoted to a Law of Nature of Scientific LawScientific Law describes what is happening in nature (how it is, not how it aught to be)

  • Science vs. Non-science vs. Pseudoscience

  • Pseudoscience: deceptive practice that uses the appearance or language of science to convince, confuse or mislead people into thinking that something has scientific validity when it does notExamples ?

  • Questions to Ask ?Scientists are healthy skeptics

  • PhrenologyFranz Gall(1758-1828)Famous AnatomistGall: So observed these facile memorizers and I noticed that they all had large and protruding eyes .Study of personality characteristics by measuring bumps on the head

  • The Theory of Phrenology: Assumptions 2. BehaviorBrain has different, distinct areas.Basic innate traitsDifferent areas responsible for different traits.b. The larger the brain area, the more prominent the trait.3. Connection

  • You need measurements to test a theory Bumps on skull(couldnt measure brain)

  • The Theory of Phrenology

  • The Theory of Phrenology: Pseudo-science popular in 19th century.

  • Senator Henry Clay(1777-1852)Reference appears in the Congressional Record in 1834.Clay suggested that the Presidents head should be examined by phrenologists and that they would find the organ of destructiveness prominently developed.

  • Wrong & too simplistic measures of brains activityThe Theory of Phrenology: Why it failed ?

  • Scientists are healthy skeptics

  • Arsenic-based bacteria: Fact or fiction?Steven Benner, a chemist at the Foundation for Applied Molecular Evolution in Gainesville, Florida told New Scientist:

    In order to measure the apparently modified DNA, it has to be put into a water-containing gel, which would rapidly dissolve any arsenic-containing chunks of DNA, but not those containing phosphorus. Since they found large chunks of DNA, it must contain phosphorus, not arsenic...
