Preface
Two professors of Geophysics Late Prof. Prabhat Kumar Bhattacharyya and
Late Prof. Amalendu Roy developed the courses on Potential Theory and
Electromagnetic Theory in 1950s for postgraduate students of geophysics in
the Department of Geology and Geophysics, Indian Institute of Technology,
Kharagpur, India. The courses had gone through several stages of additions
and alterations from time to time updating during the next 5 decades. Prof.
Bhattacharyya died in 1967 and Prof. Amalendu Roy left this department
in the year 1961. These subjects still remained as two of the core subjects
in the curriculum of M.Sc level students of geophysics in the same depart-
ment. Inverse theory joined in these core courses much later in late seventies
and early eighties. Teaching potential theory and electromagnetic theory for
aperiodof9yearsinM.Scandpredoctoral level geophysics in the same
department enthused me to write a monograph on potential theory bringing
all the pedagogical materials under one title Potential Theory in Applied
Geophysics. I hope that the book will cater some needs of the postgrad-
uate students and researchers in geophysics. Since many subjects based on
physical sciences have some common areas, the students of Physics, Applied
Mathematics. Electrical Engineering, Electrical Communication Engineering,
Acoustics, Aerospace Engineering etc may nd some of the treatments useful
for them in preparation of some background in Potential Theory. Every dis-
cipline of science has its own need, style of presentation and coverage. This
book also has strong bias in geophysics although it is essentially a mono-
graph on mathematical physics. While teaching these subjects, I felt it a
necessity to prepare a new book on this topic to cater the needs of the
students. Rapid growth of the subject Potential Theory within geophysics
prompted me to prepare one more monograph with a strong geophysics bias.
The areal coverages are different with at the most 20 to 30% overlap. Every
book has a separate identity. Students should go through all the books because
every author had his own plans and programmes for projecting his angle of
vision.
