Principle Introduction to  Quantum  Mechanics 1st teaches you all the students, a way to do quantum physics, then provides them with a additional perceptive discussion of what it suggests that .Fundamental principles area unit lined, scientific theory given, and special techniques developed for offensive realistic issues. the book contain  Two-part coverage organizes topics beneath basic theory, associated assembles an arsenal of approximation schemes with illustrative applications. In short , This book is back-geared towards teaching the reader the way to “do” quantum physics and is that the ideal selection for newcomers or people who notice the issues in different books too difficult.  hence ,   if   your area unit  interested during this  book  and additionally wish to transfer   it  in   pdf  format    then   scroll    down  and   click on the ” download HERE ” image , you’ll send to  my drive   then you will download   it terribly simply from there.

David J. Griffiths received his Becholer of Arts degree in 1964 and PhD in 1970 from Harvard University. David had taught in many colleges some of them are Hampshire College, Mount Holyoke College, and Trinity College before joining the faculty at Reed College in 1978. In 2001–2002 David was visiting Professor’s of Physics at the 5 Colleges  of  UMass, Amherst, Mount Holyoke, Smith, and Hampshire, and in the spring of 2007 he taught Electrodynamics at college of  Stanford. Although his doctor of philosophy was in elementary particle theory, most of his research is in electrodynamics and quantum mechanics. David griffiths is the author or writer of over fifty articles and four books whose name are as follows  :
  1.  Introduction to Electrodynamics 
  2.  Introduction to Elementary Particles (2nd edition, Wiley-VCH, 2008), 
  3. Introduction to Quantum Mechanics (2nd edition, Cambridge, 2005), 
  4. and Revolutions in Twentieth-Century Physics (Cambridge, 2013).

Darrell F. Schroeter is a condensed matter theorist. He received his Bachelor of Arts degree ( BA) in 1995 from Reed College and his doctor of philosophy i,e PhD in 2002 from Stanford University where he was a National Science Foundation Graduate Research Fellow. Before joining the Reed College  in 2007, He taught at both Swarthmore College and Occidental College.
