Background

Since 2001, Dr. Kuehn has served on the faculty of Wisconsin Lutheran College, where he teaches both introductory and advanced courses in the Department of 物理 and operates a fluid dynamics reSearch laboratory. He also has an abiding interest in the history and philosophy of science, which he incorporates into an annual summer course on Apologetics: the Defense of the Christian Faith. 

Dr. Kuehn is a member of the American 理论物理ical Society, he is on the advisory council of the Wisconsin Space Grant Consortium, and serves as a regular referee for the Journal of Fluid Mechanics.  

He is married to Cindy and has four children: Eva, Annalise, Iona, and Anton, and is a member of St. John’s Evangelical Lutheran Church in Wauwatosa, Wisconsin.

教学

Dr. Kuehn teaches introductory courses on astronomy, mechanics, electricity, magnetism, and light. He also teaches advanced undergraduate courses on classical dynamics,rmal physics, 电子产品, and quantum theory. 

He recently published A Student's Guide through the Great 物理 Texts; this four-volume textbook provides students and interested lay-readers with a historical and technical introduction to physics and astronomy based on the reading and analysis of classic works by scientists such as Copernicus, 库仑, 傅里叶, 麦克斯韦, 和海森堡. More information on this book can be found online.

ReSearch Interests

In recent years, Dr. Kuehn has published scientific papers on acoustic imaging of Rayleigh-Benard convection, dynamics of fluid vortex rings, and a computational analysis of tidal instabilities on multi-moon planets. 

He is currently working on using high-speed photography to study the motion of very thin fluid membranes—such as soap films.  The aim of this reSearch is to gain a deeper understanding of nearly-two-dimensional fluid dynamics, which occurs naturally in geophysical and atmospheric contexts.

More information on Dr. Kuehn’s reSearch can be found on his website.
