What is & isn’t science

  1. 1. What Is & Isn’t Science? Ref: Dr. Bruce Railsback Department of Geology, University of Georgia jschmied©2012
  2. 2. What is Science? Science is theconcerted human effortto understand, thehistory of the naturalworld & how the naturalworld works. jschmied©2012
  3. 3. What does Science use as the basis of all scientific understanding? Science uses observable, physical evidence as the basis of all scientific understanding.
  4. 4. How is Science http://www.physorg.com/news84027776.htmlDone? a. Science is done through observation of natural phenomena, b. and/or through experimentation … that tries to simulate natural processes under benjaminsternke.typepad.com/.../f_madscience.jpg controlled conditions. jschmied©2012
  5. 5. 2 Types of Science: Type 1: Observational Science Example 1a An ecologist studying the distribution of Pitcher Plants in a wetland.Example 1b An Ecologist studying the growth rate of Mink in an island ecosystem.jschmied©2012
  6. 6. Observational ScienceExample 2• A geologist examiningthe fossils in an outcrop.jschmied©2012
  7. 7. Observational Science Example 3 • An astrophysicist photographing distant galaxies to determine the formation of the Universe.jschmied©2012
  8. 8. Observational Science Example 4 • A climatologist sifting data from weather balloons on weather patterns.jschmied©2012
  9. 9. http://www.cdc.gov/niosh/mining/images%5CChemistryLabSRL.jpg 2 Types of Science Type 2: Experimental ScienceExample 1A chemist observes therates of one chemicalreaction at a variety oftemperatures to seewhat patterns emerge. http://portal.techhigh.us/Teachers/chapariana/PublishingImages/chemistry%20lab.jpg
  10. 10. http://www.nytimes.com/2007/05/15/science/15cern.html?fta=y Type 2: Experimental ScienceExample 2• A nuclear physicistrecording the results ofbombarding a particulartype of matter with to seewhat patterns emerge. http://www.nytimes.com/imagepages/2007/05/15/science/15cern_slidetwo.html
  11. 11. http://www.contractlaboratory.com/www/images/people/scientist_crystal.gif Type 2: Experimental ScienceExample 3• A biologist observing thereaction of a particular tissue tovarious stimulants isexperimenting to find patternstoo! jschmied©2012 http://www.kidsbiology.com/images/biologist-2.jpg
  12. 12. http://www.gbrmpa.gov.au/__data/assets/image/0008/17648/biologist.jpg What are all scientists attempting to do? Observing andExperimenting in order to detect patterns in nature.jschmied©2012 http://asunews.asu.edu/files/images/Algae.jpg
  13. 13. www.puzzlehouse.com/astronomer.htm Two things in common amongst all scientists: 1. Making & recording observations of nature or of simulations of nature, in order to learn more about how nature works. 2. Showing that old ideas are wrong and developing new ideas may better explain nature.jschmied©2012 http://cache.eb.com/eb/image?id=93353&rendTypeId=4
  14. 14. What Isn’t Science? Science Isn’t ArtArt is the attempt to express an individuals feelings or ideasabout something in a way that others find beautiful, graceful, or pleasing jschmied©2012
  15. 15. http://www.punaridge.org/doc/teacher/method/Default.htm What Isn’t Science? Science Isn’t ArtScience is the attempt to make public and, repeatable conclusionsabout the natural world. http://www.punaridge.org/doc/teacher/method/Default.htmjschmied©2012
  16. 16. What Isn’t Science? Science Isn’t Technologymadassgamers.com• Science doesnt make things.Scientists generate knowledge.• Engineers use scientificknowledge to generatetechnology. iphone5unlock1.com jschmied©2012
  17. 17. What Isn ’t Science? Science is often confused with Truth and Certainty. It ’s just not so… Science Isn ’t Truth • Most scientists seek Truth; they dont know or generate Truth .Ref: Dr. Bruce Railsback, Department of Geology, University of Georgia jschmied©2012Sheldon F. Gottlieb, Ph.D. Department of Biological Sciences, University of South Alabama
  18. 18. What Isn ’t Science? Science Isn ’t Certainty • Scientists use evidence to propose and test theories, knowing that future evidence may change, revise, or even reject todays theories.Ref: Dr. Bruce Railsback, Department of Geology, University of Georgia jschmied©2012Sheldon F. Gottlieb, Ph.D. Department of Biological Sciences, University of South Alabama
  19. 19. http://academics.hamilton.edu/asian_studies/home/TempleCulture.html What Isn’t Science? Science Isn’t Religion • Science and belief systems are very different, in what they try to do and in the approaches each use to accomplish their goals. jschmied©2012Ref: Dr. Bruce Railsback, Department of Geology, University of Georgia www.christchurchstellarton.ca/Sheldon F. Gottlieb, Ph.D. Department of Biological Sciences, University of South Alabama
  20. 20. http://commons.wikimedia.org/wiki/Main_Page What Isn’t Science? Science Isn’t Religion Science seeks to explain the origin, nature, and processes of the physically detectable universe. http://blog.baliwww.com/wp-content/photos/palasari_church_1.jpg Science’s underlying assumptions are tested and retested using observable physical evidence.Ref: Dr. Bruce Railsback, Department of Geology, University of GeorgiaSheldon F.

  21. 21. The Three Basic Questions Science Asks…. http://evolution.berkeley.edu/evosite/nature/I3basicquestions.shtml #1 What’s there: The astronaut picking up rocks on the moon, The nuclear physicist bombarding atoms, The marine biologist describing a newly discovered species, The paleontologist digging in promising strata, are all seeking to find out…..http://starchild.gsfc.nasa.gov/Images/StarChild/sp “What’s there?”ace_level2/aldrin_big.gif jschmied©2012
  22. 22. The Three Basic Questions ScienceAsks…. http://evolution.berkeley.edu/evosite/nature/I3basicquestions.shtml #2 - How does it work? A geologist comparing the effects of time on moon rocks to the effects of time on earth rocks, The nuclear physicist observing the behavior of particles, The paleontologist studying the locomotion of an extinct dinosaur, all are asking….. “How does it work?” jschmied©2008
  23. 23. The Three Basic Questions Science Asks…. http://evolution.berkeley.edu/evosite/nature/I3basicquestions.shtml #3 How did it come to be this way? Each of these scientists tries to reconstruct the histories of their objects of study. Whether these objects are rocks, elementary particles, marine organisms, or fossils, scientists are asking, “How did it come to be this way?”jschmied©2012
