In Memory of Amar G. Bose, MIT Professor and Founder and Chairman of the Bose Corporation: It was a privilege being your student—and members of the next generation of Deitels, who heard our dad say how your classes inspired him to do his best work. You taught us that if we go after the really hard prob- lems, then great things can happen. Harvey Deitel Paul and Abbey Deitel A01_DEIT3397_02_SE_TP.fm Page 5 Monday, July 7, 2014 8:26 AM
