Academic Miscommunication in Physics
Scott C. Scharlach
Academic Miscommunication (AM) is the phenomenon of a professor's expectations, beliefs, or goals in the classroom differing from those of the students. In this study, a survey was…
The Hyperbolic Tangent as an Educational Tool for Teaching Variable Acceleration
Scott C. Scharlach
This paper presents an approximate analytical solution to the Falling Astronaut Problem by means of the hyperbolic tangent, and it explores the educational opportunities presented…
Pedagogical Implications for the Falling Astronaut Problem
Scott C. Scharlach
This paper outlines a deceptively complex problem in classical mechanics which the paper names the "Falling Astronaut Problem," and it explores a method for teachers to implement t…
An Optical Analysis of Sunspots as Predictors of Geomagnetic Storms
Matthew Shelby, Scott Scharlach, Petar Matejic +2
Although a variety of phenomena may create a geomagnetic storm on Earth, the most severe geomagnetic storms arise from solar activity, and in particular, coronal mass ejections (CM…
The Kinematic Distance to NGC 6309
Scott C. Scharlach, Colton G. Morgan
We report an updated value for the distance to the planetary nebula NGC 6309 (the Box Nebula). The distance is found through two Kinematic Distance Methods (KDMs): the system of tw…
