University Policy Statements in Your Syllabus (#1) • UNIVERSITY NOTICE REGARDING PERSONAL CONDUCT: The University at Stony Brook expects students to maintain standards of personal integrity that are in harmony with the educaNonal goals of the insNtuNon; to observe naNonal, state, and local laws and University regulaNons; and to respect the rights, privileges, and property of other people. Faculty are required to report disrupNve behavior that interrupts faculty’s ability to teach, the safety of the learning environment, and/or students’ ability to learn to Judicial Aﬀairs. University Policy Statements in Your Syllabus (#2) • ACADEMIC INTEGRITY SYLLABUS STATEMENT: Each student must pursue his or her academic goals honestly and be personally accountable for all submiVed work. RepresenNng another person's work as your own is always wrong. Any suspected instance of academic dishonesty will be reported to the Academic Judiciary. For more comprehensive informaNon on academic integrity, including categories of academic dishonesty, please refer to the academic judiciary website at hPp://www.stonybrook.edu/uaa/

What is science? • Trying to understand the world through observaNon and experimentaNon • Modern science: the ScienXﬁc Method – see next slide The scienNﬁc method What is science? • If it’s not testable, it’s not science • If results are not independently repeatable, they are not accepted • Natural processes are testable. Supernatural ones are not. – => Supernatural explanaNons are not part of science. Two types of experiments • ComparaNve – Compares an outcome of interest in natural condiNons with diﬀerences in measurable variables • see example on upcoming slide • Controlled – One variable is manipulated by invesNgator, all others are controlled – Tests the eﬀect of the manipulated variable on a variable outcome of interest (the response variable) • see example on upcoming slide a controlled experiment research by Tyrone Hayes and colleagues a comparaNve experiment research by Tyrone Hayes and colleagues InducXve vs. deducXve methods • InducNon: from the speciﬁc to the general – ObservaNons and experiments on speciﬁc instances are assumed to apply to most or all instances: generality – General conclusion is made from the weight of evidence (o\en staNsNcal) of many observaNons/experiments – Sadava text: Hayes et al. used inducNon to formulate possible answers to the quesNon: “What is causing frog developmental abnormaliNes?” • DeducNon: from the general to the speciﬁc – A series of premises which lead to a conclusion that must be true if all the premises are true • Premises are seen as general “laws” • Conclusion is for a speciﬁc case of interest – Sadava text: Hayes et al. used deducNon to formulate predicNon based on the hypothesis: “Atrazine exposure causes frog developmental abnormaliNes.” A well designed experiment: • can potenNally provide support or falsify a hypothesis • the best experiments provide support for a speciﬁc hypothesis in exclusion of most or all other hypotheses – these are fairly rare – many experiments provide evidence for or against hypotheses but also indicate that the hypothesis is too simple • system is more complicated than originally thought falsiﬁcaNon • frog atrazine experiment – atrazine in the environment was associated with feminizaNon of male frogs • ‘correlaNon’ is not ‘causaNon’ • laboratory experiment would have falsiﬁed the hypothesis of atrazine causing the anomalies if there was no diﬀerence between treated and control frogs – a hypothesis is only scienNﬁc if it has the potenXal of being rejected by observaNon or experiment What is a scienNﬁc theory? • It’s not a hunch or speculaNon • A set of interrelated, well‐tested hypotheses that is supported by a large body of observaNonal and experimental data. – Theories are not absolute truth ‐ they can always be reﬁned and augmented. – Important: ScienNﬁc theories are always open to new tests. – Hypotheses and theories are accepted and rejected based on weight of evidence What is a theory? •
• Atomic theory GravitaNonal theory Quantum theory Much of biochemistry and human medicine is based on well established theoreXcal frameworks – These are always evolving • EvoluNonary theory • Solid scienNﬁc theories lead to: – Smarter and more expansive hypotheses and research programs (new knowledge) – Useful and reliable technology (e.g. disease therapies) "Nothing in biology makes sense except in the light of evoluNon.” ‐Theodosius Dobzhansky (1973) www.pbs.org/.../06/ 2/image_pop/l_062_04.html "If evoluNon is a play, then ecology is the stage upon which it is performed." ‐Marston Bates (1960) http://hbs.bishopmuseum.org/dipterists/images/bates-m.gif ...
