Biography Dean Sieglaff Image
Dean Sieglaff received a Bachelor of Arts cum laude from Saint Olaf College, Northfield, Minnesota in 1988, where he majored in physics and mathematics. He received a Master of Arts and Doctor of Philosophy from Rice University, Houston, Texas, by 1993, for work in the area of experimental atomic collisions, particularly those involving atomic oxygen. Dean took a post-doctoral research fellowship with the Pacific Northwest National Laboratory, at the Hanford Nuclear Reservation outside of Richland, Washington, working in an analytical chemistry group in the area of electron-molecule physics and negative ion mass spectrometry. He also started teaching at that time as an adjunct faculty member of Columbia Basin College, Pasco, Washington. In 1995, he received an assistant professorship with the Department of Physics, Grove City College, Grove City, Pennsylvania. During his time at Grove City College, Dean continued to carry out atomic and electronic collisions research at Rice University′s Atomic and Molecular Collisions Group in the summers. In January of 2001, Dean moved to the San Francisco Bay Area to take an electron beam engineering job with the silicon valley-based KLA-Tencor Corporation, the world leader in semiconductor yield management. Called back to the life and work of professor in the liberal arts, Dean began a tenure-track associate professorship with the Department of Physics and Astronomy, Augustana College, Rock Island, Illinois in the fall of 2004. In the fall of 2008, Dean began a tenure-track associate professorship with the Department of Physics and Astronomy, Nebraska Wesleyan University, Lincoln, Nebraska.  Dean continues to work as scientific consultant and contract engineer with KLA-Tencor's ebeam division.  In the summer of 2013 Dean began a collaboration with Professor Timothy Gay in the Department of Physics at UNL to explore and improve techniques to create beams of spin-polarized electrons through collisions with optically pumped Rubidium atoms.

Dean has three sons Sander (age 15), Jonas (age 13), and Charles (age 11).

Fast Beams Laboratory Dean recently received a significant amount of equipment from Rice University for the experimental study of electronic and atomic collisions, which he is currently bringing to an operating state with the help of his students, in the hope of continuing and extending the world-class experimental measurements for which the Rice lab was well known. The lab is currently housed in Nebraska Wesleyan University's Olin Hall of Science, Room H.  Recent work in the lab is highlighted here.
Mathcad Mathcad is a technical calculation and math visualization application created in 1986 and currently sold by Parametric Technology Corp., an industry leader in engineering computing and modeling (and creator of Pro-E).  Mathcad is unique among its competitors in two respects.  First, it understands, converts, and reconciles physical units.  Second, it is intuitive and easy to use.  Both of these facts make it the perfect tool for introduction within all levels of undergraduate physics instruction.  We use Mathcad in introductory physics to help students solve and calculate.  We use Mathcad in upper level physics to help students visualize and explore advanced concepts.

VERY IMPORTANT:  To download file, DO NOT JUST CLICK ON IT.  In Firefox and Chrome, right-click Save Link As...  In IE, right-click Save Target As..., then save as type "all files," and change the file extension to "xmcd."  If you just click on it (in either browser), it will be interpreted as an XML file because it does have XML content.  If using Safari, or other, something similar to the above will have to be done.

A "starting point" sheet, which has preset formats for equations and text, can be found here.

A good general purpose Mathcad tutorial covering basic expression and variable definition, calculation (with units), symbolic solving, graphing, etc. can be found here (*.xmcd file, see above note).  It was created in Mathcad 13.

A  list of hints involving the use of Mathcad designed to avoid frustration can be found here (*.xmcd file, see above note).

A poster entitled "Using Mathcad to Promote Expert Problem Solving in Upper-Level Physics," presented at the New Faculty Workshop Reunion, November 5-6, 2010, at the American Center for Physics, AIP Headquarters, College Park MD, can be viewed here as a PDF.  The following is the abstract for that presentation:  Upper level physics courses have traditionally emphasized “pencil and paper” analytical problem solving.  Mathcad is a technical calculation platform that offers ease of use, incorporates physical units, and provides students the means to numerically simulate and visually explore the fascinating principles of advanced physics, with the overarching goal of testing and verifying their own analytical solutions by numerical means.  Examples will be presented from a broad spectrum of upper-level physics topics.

Eastridge Recreation Association I serve on the Board of Directors for the Eastridge Recreational Association (ERA), the primary function of which is to oversee the operation of the Eastridge neighborhood swimming pool at 830 Sunrise Road, Lincoln.  My local copy of the repair project site can be found here.
Growing in Faith Through the Lens of Science I am involved in a project at First Lutheran Church, Lincoln NE that is funded by the Scientists in Congregations project.  The goal is to support the healthy, beneficial coexistance of science and faith within our faith community, and within society as a whole.
