light by very massive astrophysical objects (gravitational lensing). This phenomenon cannot be produced in a terrestrial experiment but it can be observed in many places in the sky.” 3. What is a scientific model and what must the model be able to do to be useful? See #2 above. It has to work and be consistent with the observed facts. In time the celestial sphere model of our ancestors was replaced with a more accurate model. Although obsolete such a model works well today for navigators on the high seas. Inaccurate but useful language still persists and conveys meaning. Every day we say it is a beautiful sunrise. Often different models (hypotheses) compete till a theory emerges by the scientific selection process. Competing hypotheses define the boundaries and frontiers of science. 4.How can an incorrect scientific theory still be considered a good scientific theory? See #3 above 5.*What distinguishes a scientific truth from a religious truth? Observations that must be available to all combined with experiments and peer reviews are essential ingredients that separate science as a way of knowing from religious truths. Also key is that a scientific explanation requires that it must be

possible in principle to be proven false. This last point negates an explanation that involves the supernatural. Nobel Prizes have been won by scientists of many faiths. To do science takes faith that maybe there is a rational explanation for this universe we find ourselves as participants. As Martin Luther King, Jr. says, “Faith is taking the first step even when you don't see the whole staircase.” Thoughts from others… Faith is knowledge within the heart, beyond the reach of proof. — Khalil Gibran Where faith commences, science ends. Both these arts of the human mind must be strictly kept apart from each other. Faith has its origin in the poetic imagination; knowledge, on the other hand, originates in the reasoning intelligence of man. Science has to pluck the blessed fruits from the tree of knowledge, unconcerned whether these conquests trench upon the poetical imaginings of faith or not. — Ernst Haeckel Science without religion is lame; religion without science is blind.-Albert Einstein 6. In what way can scientists use astronomical observations to find the correct explanations for physical events here on the Earth? We are a part of Nature not apart (isolated or separate) from it. This class will illustrate many “down to earth” examples of how what we learn “out there” applies to a better understanding of the operation of our planet. In part this class can be thought of as an “owner’s manual” for we earthlings. The week 1 assignment-Astronomy Applications highlights some direct technological innovations that have impacted our daily lives. 7.*How do we know that the laws of physics on the Earth are the same throughout the rest of the universe?

    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.
