What are weather and climate? Most people think they know but if you ask people to explain the differences and similarities you're bound to get a range of answers. Weather affects not just our daily activities but other important aspects of society such as transportation, commerce, security and agriculture. Most people understand what weather is to some extent. Climate and climate change are concepts that evoke strong emotional responses from people but are less well understood. In this class, students examine fundamental issues such as the greenhouse effect, severe weather, and global weather patterns and how they relate to a changing climate. Instruction in the lectures will provide the basic knowledge needed to understand these issues. In the discussion sections, students will be divided into groups to address the implications of these topics through group projects.

Grad Meth: Reg, P-F, Aud
GenEd: DSNS
Credit only granted for: ASTR100, ASTR101, ASTR120, or ASTR130.
Take a tour of the universe! This course wanders through the night sky, learning about phases of the Moon and eclipses, and then stops by the different planets, moons, and small bodies within our solar system. After that, it's on to bigger things, with stops by the Sun and other stars, learning about how they live and die - possibly in supernovae! - before exploring the weird objects left behind, such as neutron stars and black holes. All of these objects are within our galaxy, the Milky Way, which is one of uncountable galaxies in the universe! A tour wouldn't be complete without thinking about where it all came from: the Big Bang. This course is for non-Astronomy majors and is mostly descriptive with some algebra and trigonometry.

Black holes are the most exotic prediction of Einstein's Theory of General Relativity and, amazingly, the Universe seems to manufacture these bizarre objects in copious numbers. As well as being the ultimate laboratory for studying the nature of space and time, they drive some of the most energetic and extreme phenomena known to astronomers (with quasars and gamma-ray bursts being just a couple of examples). In this introduction to the physics and astrophysics of black holes, we start by examining the basic physics of black holes, which fundamentally means understanding gravity. We then look at the nature of stellar-mass black holes and supermassive black holes. We will discuss the fairly recent realization that black holes may be crucial agents for regulating the growth of galaxies. Finally, we dive into the realm of theoretical physics and probe how black holes may provide a route for uncovering new laws of physics governing the structure of space and time.

HNUH
University Honors
HNUH248D
Biophysics of Language
Credits: 3
Grad Meth: Reg, P-F, Aud
GenEd: DSNS, SCIS
Cross-listed with: LING272.
Credit only granted for: HNUH248D or LING272.
Can my dog ask questions - and how would my cat answer? A traditional debate concerns whether language is a unique human faculty. While communication systems are common - cetaceans whistle and sing, songbirds and parrots are vocal learners, bees convey information about energy sources - the specific properties of human language, involving finite mental means to socially yield unbounded messages, have not been easy to find in other species. This course delves into the question of whether this quality is unique to humans. The only precondition to take it is the willingness to approach the matter scientifically, starting with notions from a Computational Theory of Mind. Students may bring to bear upon these questions insights from linguistics, psychology, neuroscience, molecular biology, etc., to debate how an abstract systematic behavior can arise within an animal brain, and what that says about evolution.
HNUH258C
Nature at Risk: Extinction, Consequences, and Strategies
Credits: 3
Grad Meth: Reg, P-F, Aud
GenEd: DSNS, SCIS
How should we prioritize among all the species at risk of extinction? This course will grapple with the complex and consequential process of extinction from biological, geographical, and mathematical perspectives. Core themes will include the 1) nature(s) of extinction risks, 2) potential consequences of different kinds of extinction, and 3) considerations involved in setting priorities. Students will explore, handle, and analyze relevant data (e.g., evolutionary trees, species occurrence records, population censuses) to better understand extinction processes. With the aid of AI-generated hypothetical species, we will investigate hidden biases, debate the consequences of our choices, and explore possible prioritization strategies.
HNUH 258C is the required Big Question course in the Conserving Biodiversity thematic cluster. Conserving Biodiversity courses will be offered through Spring 2026.
