Administrivia This is a 1 unit course. This is a 1 unit course. Unlike most science courses it is open for discussion. Unlike most science courses it is open for discussion. –There is no controversy over Newton’s Laws of Motion but there might be over Newton. Your participation is critical- take part!!!!! Your participation is critical- take part!!!!! Additional sessions: Additional sessions: –If there is interest we can meet on Thursdays, same time, for open discussions. Web site Web site =ISC =ISC6416 has outline, reading list, and write up that I prepared to introduce you to this subject.

Schedule Discussion of what is a culture, what is the Culture of Science, what are scientific ethics, what can go right/wrong – some comments on fraud and pathological science. Discussion of what is a culture, what is the Culture of Science, what are scientific ethics, what can go right/wrong – some comments on fraud and pathological science. How did science get started?

The Copernican Revolution and the Newtonian Synthesis The Copernican Revolution and the Newtonian Synthesis Scientific Controversies Scientific Controversies Conservation Laws, Thermodynamics and the Arrow of Time Conservation Laws, Thermodynamics and the Arrow of Time Electricity, Magnetism and Electromagnetics – Maxwell, Symmetry and Unification Electricity, Magnetism and Electromagnetics – Maxwell, Symmetry and Unification Measurement, Relativity, Einstein and Everything Else Measurement, Relativity, Einstein and Everything Else Quantum Mechanics – Part I Quantum Mechanics – Part I Quantum Mechanics – Part II Quantum Mechanics – Part II Quantum Mechanics – Part III Quantum Mechanics – Part III Five Experiments that Define Modern Optics Five Experiments that Define Modern Optics Time and the Past and Future Histories of the Universe Time and the Past and Future Histories of the Universe Magic Numbers Make the Universe: The Miracle of Stars and Why We Are The Modern World- We Owe it to Physics

More Stuff One evening, after we have discussed Scientific Controversies, we will view a dramatization of the trial in Pennsylvania over Intelligent Design and Science.

Some questions I hope to give you some material to think about such questions in this course. How old is the universe? How do we fit into the vastness of the universe? Are we important? Are we important in the grand scheme of the universe? Why do answers to these questions matter and what kind of answers are important? How big is it? How old is the solar system?

A definition Science is a method of interrogating reality, a cumulative process of testing new and more refined explanations, not an assertion of dry, unalterable facts. Science is a method of interrogating reality, a cumulative process of testing new and more refined explanations, not an assertion of dry, unalterable facts. It is a way of asking questions, not of imposing answers. It is a way of asking questions, not of imposing answers.

What is science? Common beliefs Common beliefs Common behaviors Common behaviors Common attitudes Common attitudes Common ways of thinking/seeing Common ways of thinking/seeing Common modes of living Common modes of living Common arts Common arts Common technologies/sciences/views of the world and universe Common technologies/sciences/views of the world and universe

Some say Science is the subject of what can be proven wrong. Science is the subject of what can be proven wrong. You can not disprove belief!!!! You can not disprove belief!!!!

How does science work? The two most important questions in science: The two most important questions in science: –What can I know? –How can I know it? Religion and science part ways over the first. Religion and science part ways over the first. –Religion thinks it can know why! –Science thinks it can know how! The answer to the second is what defines modern science. The answer to the second is what defines modern science. –Methodology matters as much as the question itself.

Progress in Science Scientists use data to form a model or paradigm and then Scientists use data to form a model or paradigm and then –Test it and test it again and again.  Here the methodology matters –The tests are either meaningful or not. –How do you know. –If anomalies are found that do not fit they  Modify the paradigm, or  Replace it.

Who is a scientist? All real scientists exist on the frontier. All real scientists exist on the frontier. –They deal with the unknown! –They develop tools to probe the unknown. –They explore in a disciplined manner. Scientists do not torture the data to find a result they Scientists do not torture the data to find a result they –torture the experiments to be sure the data is correct and meaningful.

Properties of science Experiments must be reproducible. Experiments must be reproducible. –If A gets a result at her lab then B must get the same result in his. The results must be expandable The results must be expandable –One must be able to:  Build on it.  Learn more from it.  Use it as a foundation to build new structures.

Properties of scientists Honest Honest Ethical Ethical Trustworthy Trustworthy Not biased Not biased … Examples of this gone astray are pathological science Examples of this gone astray are pathological science –Polywater –Infinite dilution –Cold fusion

Other examples Scientists whose bias clouds their science: Scientists whose bias clouds their science: –Creationist science –Intelligent design –Phrenology –Racial stereotyping –Extreme global warming

What is a Culture Common beliefs Common beliefs Common behaviors Common behaviors Common attitudes Common attitudes Common ways of thinking/seeing Common ways of thinking/seeing Common modes of living Common modes of living Common arts Common arts Common technologies/sciences/views of the world and universe Common technologies/sciences/views of the world and universe

Science affects culture Ideas Ideas Inventions Inventions Manners of thinking Manners of thinking Views of our place in the Universe Views of our place in the Universe Language Language Everyday life Everyday life

Culture affects science What science is conducted What science is conducted Where Where By whom By whom Conversion to technology Conversion to technology Utilization Utilization Diffusion of scientific knowledge Diffusion of scientific knowledge

An example Science affects culture Science affects culture –Manhattan project leads to nuclear weapons –Modifies how nations behave. –Results in no WW III (yet?) Culture affects science Culture affects science –Huge funding for atomic and nuclear science. –Scientists are lionized. –Eventually scientists become  Nerds, geeks, awkward, unpopular  Millionaires, Billionaires, sponsors of next generation of scientists

For fun- by next Tuesday Using what you know as scientists design Using what you know as scientists design an extraterrestrial, intelligent lifeform. What properties must it have, what capabilities, and what technologies would it have to have for us to realize that it was an intelligent lifeform. Note that here on earth we still can’t determine how intelligent some species might be.
