### SAGES FIRST & UNIVERSITY SEMINARS

#### FSCC 100. Life of the Mind

This four credit-hour course provides an introduction to various dimensions of academic life. It will be characterized by intense yet open-ended intellectual inquiry, guided by reading from primary as well as secondary sources, and will include practice in written and oral communication in small groups. Each seminar is led both by a faculty member and a writing co-instructor. The goals are to enhance basic intellectual skills of academic inquiry, such as critical reading, thoughtful analysis, and written and oral communication; to introduce basic information literacy skills; to provide a foundation for ethical decision-making; to encourage a global and multidisciplinary perspective on the learning process; to facilitate faculty-student interactions; and, in the most general sense, to provide a supportive common intellectual experience for first-year students at Case. This seminar is about finding our themes, both as individual writers, and as a class. Authors Gladwell, Foer and Sandel will provide the initial grist for our mill. Students will make as many choices as is feasible in setting the direction of the course. (*offered in fall 2011 by P. Kernan*)

#### FSCC 100. Life of the Mind

This four credit-hour course provides an introduction to various dimensions of academic life. It will be characterized by intense yet open-ended intellectual inquiry, guided by reading from primary as well as secondary sources, and will include practice in written and oral communication in small groups. Each seminar is led both by a faculty member and a writing co-instructor. The goals are to enhance basic intellectual skills of academic inquiry, such as critical reading, thoughtful analysis, and written and oral communication; to introduce basic information literacy skills; to provide a foundation for ethical decision-making; to encourage a global and multidisciplinary perspective on the learning process; to facilitate faculty-student interactions; and, in the most general sense, to provide a supportive common intellectual experience for first-year students at Case. (*offered in fall 2009 by J. Ruhl and P. Kernan*)

#### FSNA 103. Energy and Society

This four-credit-hour course provides an introduction to collegiate writing and to various dimensions of academic life, but will focus on the critical appreciation of the world of energy. Currently, most of the world runs on non-renewable resources; this course is designed to help students develop viewpoints about these issues, and to express themselves in a clear, coherent way. The class will involve both literacy and numeracy, and students will learn to become comfortable handling some of the quantitative measures of energy use. The class will be characterized by intense yet open-ended intellectual inquiry, guided by reading, lectures and discussion, and will include practice in written and oral communication individually and in small groups. (*offered in fall 2012 and previous falls since 2005 by P. Taylor, G. Chottiner & J. Ruhl, fall 2013 -2015 by P. Taylor*).

#### FSNA 124. The Challenge of Sustainability

This four-credit-hour course provides an introduction to collegiate writing and to various dimensions of academic life, but will focus on the critical appreciation of the challenges we face in transitioning – or failing to transition – to a sustainable society. Climate change, along with increased development and population, are altering the natural environment we live in and rely on. This course will review some of the current and future impacts of these changes, and explore alternate paths forward and how they might be forged. The class will involve both literacy and numeracy, and students will learn to become comfortable handling some of the quantitative measures relevant to sustainability issues. The class will be characterized by intense yet open-ended intellectual inquiry, guided by reading, lectures and discussion, and will include practice in written and oral communication. (*offered in fall 2010, 2014, 2015 by J. Ruhl*)

#### FSNA 138. Light

This course explores Light, otherwise know as visible electromagnetic radiation. We will examine what light is in its various forms; how it is created and detected; how we perceive it; and how it has influenced our evolutionary development, our technological, artistic, and religious cultures, and our conceptions of space and time. Students will discuss topics suggested by the course readings and by exposure to the many scientific activities, historical artifacts, and artistic works on the CWRU campus and at other local institutions that involve light in a significant way. (*initial offerings in fall 2012 & 2014 by K. Kowalski, approved as a regular offering*)

#### USNA 228. Time

This seminar course will explore the nature of time from many stances, including those of Psychology, Biology, Technology and Philosophy. Yet time is central to Physics, and in Physics we will orient our explorations of time. Our understanding of time has sharpened a great deal in the last few centuries, the most obvious markers being Newton’s Absolute time, which remains entrenched in modern culture, and its subsequent physical overthrow by Einstein’s relativity. Given the physical primacy of Einstein’s time, many questions arise: How malleable is the concept of time? Is there a fact of time? Can the present be defined? The past? The future? The successes of modern Cosmology lead us to ask: Was there a beginning of time? Will time end? The symmetry of fundamental physical laws with respect to the direction of time, counterpointed by asymmetric phenomena, lead to: Is there a master arrow of time? Is the flow of time an illusion? In this course we will investigate what “Time” is telling us about the natural world and ourselves. (*offered in spring 2013, 2015, 2016 by P. Kernan*)

#### USNA 263. Reading and Writing Science

This seminar will examine the ways in which science is communicated to the non-scientist public. The goals are to teach the students to be critical consumers (readers, viewers, and/or listeners) of science as it appears in the public sphere, and to teach the students how to write about science for non-scientists. The course is co-taught by a scientist with experience writing for and speaking to the public, and by a science journalist. Students will engage with popularized science in a variety of formats–including newspaper and magazine articles, radio and television news and talk shows, television documentaries, internet postings, public lectures and popular books. We will make particular use of University Circle opportunities, such as public lectures both at CWRU and at neighboring institutions (e.g. the Explorer series at CMNH)–attending the lectures and, if possible, interacting with the speakers as a class. Several local or visiting science authors will be invited to participate in class discussions on their books. We will pay particular attention to how scientific stories are told in “the media”, through weekly examinations of science news stories. In relation to all these forms of communication, we will learn to ask who the author(s) is/are, how his/her/their training and relation to the story, as well as other factors, affects how the story gets told, and how to interrogate authorial claims. We will also practice writing science stories, with each student producing at least one piece for possible publication through university internal communications channels, and perhaps, ultimately, for distribution to external news organizations. (*offered in spring 2012 by G. Starkman*)

USNA 288C. Physics for Future Innovators & World leaders

We live in an increasingly technological society. Advances in technology improve our lives in countess ways, but they sometimes produce problems and challenges that are so complex that the average business or political leader cannot understand them–and therefore cannot make effective decisions to address them. Whether the problem is what to do about climate change, how to identify investment-worthy energy sources, how to provide sufficient and sustainable food and energy to the world’s population, or how to determine if an investment trend is a dangerous bubble, we will find better solutions if we have leaders who have an adequate understanding of basic physical principles and how physical “laws”–such as conservation of energy, exponential growth and decay, and gravity–can dictate the sagaciousness or feasibility of various solutions and applications. This course is designed to equip students with that knowledge. Using very little math, we will consider how an understanding of basic physical principles related to energy, force, space, electromagnetism, waves, and exponential growth can help us make sense of some of our most pressing technological problems. In addition, we will also examine issues related to the social uses of technology, including realistic timelines for technological development, incremental versus radical improvements, rapid estimation, identification of need, cost-benefit analysis, identifying spin in news reports, intellectual property rules, and ethical citation of sources. Class time will consist of group discussion, student presentations, and “Fermi Problems” (complex, creative problem solving with order-of-magnitude estimations). (*offered in spring 2012, 2015, 2016 by E. Caner*)
