“A theory is not some hunch, or half-baked idea that you come up with while taking a shower, or being under the influence of something or other. A theory, as scientists understand the meaning of the word, is a scientifically tested principle or body of principles that incorporates and explains a significant body of evidence.” Wallace Tucker Slide 46: Loosely we say, oh that just your theory (opinion)…In science theory is not an opinion…an opinion in science is a tentative explanation-hypothesis… Slide 52: An observation is what we experience through our senses and our sense extenders. If circumstances are the same and all observers experience it (available to all whether you are Chinese or Canadian) it then becomes a fact. Slide 53: In astronomy we need to be aware of our observational position. Behavior that we see with our eyes in our backyard does not match the view we see in our mind’s eye-the view as an angel in heaven. Slide 54: Observations require an explanation. Often multiple explanations are advanced. Hopefully one idea/explanation will emerge as “truth”. Rigorous testing and checking of the tentative

explanations is the next step. How do we know what we know…In astronomy experiments often can be difficult if not impossible to perform. No one was around to directly observe the formation of the Solar System but many clues are available to us to mentally recreate the origin process. Slide 55: Not too long ago it was hard to imagine rocks falling from clouds. Slide 56: Doubt powers the process of science… Slide 59: Even though we may be diligent and have almost all the information we still might not be absolutely certain that our theory is true. Yet many explanations are accepted because of the high probability that they are correct even though some puzzle pieces are missing. In the puzzle it is highly likely that the young girl is sitting on her bed with her cat. But it might also be true that she is sitting in solitary and that the unusual shape of the puzzle piece just completes the general background of her room Slide 60: Police officers are not always on the scene when a crime is committed. Likewise a scientist must assemble the clues into a convincing case before it is generally accepted. Slide 66: This is a big step to take. Some cultures revere Nature and their traditions would not allow such separation. Slide 67: Newton’s work allows us to call this place Uni verse (oneness). There was a time when it was thought that fossils were placed in the rock to test one’s faith. Einstein allows us to be an optimist about our circumstances-we have a chance. Like Galileo he reminds us that the mind is a beautiful gift that has been given to us. To not use it would show a lack of appreciation for such a grand gift. Popper restates Strobel’s thought, “Without room for doubt, there would be no room for self-correction”… Slide 68: Reasonable assumptions… Slide 70: Compared to me, the Amish of southeastern Minnesota live in a more ecological harmony with Earth than I do. I also know that they would not build the Mayo Clinic or Hubble Space Telescope.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
