Newsletter of the Department of Physics, University of Arkansas REFLECTIONS Volume X, Number 1 Summer 2002 UNIVERSITY OF ARKANSAS RECEIVES THE URSA WEB THE LARGEST GIFT TELESCOPE PROJECT IN HISTORY OF U.S. PUBLIC HIGHER EDUCATION Undergraduate Research Studies in Astronomy, or URSA, is a project funded by the National Science The University of Arkansas received a $300 Arkansas to realize its vision as a nationally Foundation, with matching support from the million commitment from the Walton Family competitive, student-centered research university University. The goal of the project is to enable all Charitable Support Foundation to establish and serving Arkansas and the world,” White added. undergraduate astronomy students to participate in endow an undergraduate honors college and The Walton Family Charitable Support research projects during each astronomy class they endow the graduate school. The gift is the largest Foundation was founded to support specific take. The hope is that this will foster an inventive ever made to a U.S. public university. The gift charities in the state of Arkansas by the family of research spirit in our students and lead to also ranks as the fifth largest ever made to an the late Sam M.
