This course develops a planetary perspective on the evolutionary processes that shaped Earth throughout history. We will examine why Earth is habitable, that is, why any kind of life can live on it, we will discuss the unique influences that biological processes and atmosphere/ocean systems have on each other, and we will review current notions of climate change, including evidence for the influence of human activities on it. This interdisciplinary treatment of Earth and its sister planets will encourage students to think about how science and engineering must be applied to today's challenges if humankind is to have a promising future on (and off) this planet. PTYS 170A1 is a Tier I Natural Science course in the University's general education curriculum. This course is co-convened (cross-listed) with ASTR 170A1.
Spring 2019 Undergraduate Courses
The Universe and Humanity: Origin and Destiny (3)
The Universe And Humanity: Origin And Destiny places Earth and humanity in a broad cosmic context. Topics range from the Big Bang cosmology to human consciousness with emphasis on the events and evolutionary processes that define the physical universe and our place in it. PTYS 170B2 is a Tier I Natural Science course in the University's general education curriculum. This course is co-convened (cross-listed) with ASTR 170B2.
Our Golden Age of Planetary Exploration (3)
PTYS 206 emphasizes the part of the universe that is within reach of direct human experience and exploration. We will review current understanding of the contents of our Solar System and emphasize the processes that unite all of the planets and smaller bodies, such as tectonics, weathering, cratering, differentiation, and the evolution of oceans and atmospheres. The course will build on this knowledge to understand humankind's motivation to explore beyond our Solar System, especially to search for planets around distant stars and to look or listen for evidence of life elsewhere in the Universe. PTYS 206 is a Tier II Natural Science course in the University's general education curriculum. PTYS 206 is cross-listed with ASTR 206. Course requisites: Two courses from Tier One, Natural Sciences.
Astrobiology: A Planetary Perspective (3)
We will explore questions about the origin, evolution, and future of life on Earth and the possibility of life arising independently elsewhere in the Universe. We will examine what it means for a planet to be habitable, both in terms of basic necessities for living organisms to function and environmental limits to their ability to survive. Finally, we will review different approaches for searching for life within the Solar System and beyond using direct and remote sensing techniques. PTYS 214 is a Tier II Natural Science course in the University general education curriculum. PTYS 214 is cross-listed with ASTR 214 and GEOS 214. Course is equivalent to ASTR 202 (students may not receive credit for both courses).
Life on Mars: Fact and Fiction (3)
Life on Mars is likely to be a scientific "hot topic" for the rest of your life. After this class, you should have a good understanding of what planetary scientists think about the chances of life on Mars, why they think that, and how current and future spacecraft missions plan to address that. In addition, since life on Mars has been the subject of some classic science fiction for more than 100 years, with no signs of letting up, you should understand how that science fiction relates to science. My real goal is that as the current debate resolves itself, and as spacecraft explore Mars during the next few decades, you'll understand what's going on and which claims are important, and that as you read or watch science fiction dealing with Mars, you'll appreciate how it relates to past and present science and sci-fi. PTYS 342 may not be applied toward the PTYS undergraduate minor.
Physics of the Solar System (3)
Survey of planetary physics, planetary motions, planetary interiors, geophysics, planetary atmospheres, asteroids, comets, origin of the solar system. Prerequisites: PHYS 142 or 251. PTYS 403 is a required course for the PTYS Minor. Equivalen to ASTR/GEOS/PHYS 403.
