PREFACE: COMMEMORATING THE LIFE AND
TIMES OF ART BERGLES (1935 – 2014): HE
PEDALED FAR AND WIDE, MADE ADIFFERENCE . . . AND THE TRAIL IS ANENRICHING LEGACY

aneka-samshayo_chchhedi, paroksh_ārthasya darshakam |sarvasya lochanam shāstram, yasya nāsti andhaiva saha ||– Hitopadesh, 1:101
This verse in Sanskrit from the opening chapter of the Hitopadesh translates as follows: the resolver of many doubts and misgivings, the revealer of things, ideas, andunderstandings that are not obvious or are invisible, is the eye of knowledge gained
from learnings of sciences from the shāstra2 (or a compendium of knowledge), without which one is blind or ignorant. From very ancient times it was acknowledgedthat scientific inquiry, whether through “mental explorations” (theoretical and analytical constructs) or careful and extensive laboratory experimentations, is the true “eye”
through which to see things through and to bring sustainable order in the affairs ofmankind. We celebrate the spirit of this opadesh in the published pages of this special
issue of the Journal of Enhanced Heat Transfer. These papers are not just contributions dedicated to the memory of the late Professor Arthur E. Bergles (1935 – 2014);
they are current and state-of-the-art research reports on a variety of topics that havewide-reaching impacts in the field of enhanced heat and mass transfer. Some of these
1 Hitopadeśa, a collection of fables and tales written in Sanskrit in both verse and prose, is considered

to have been written by Narayan Pandit (~8th century), perhaps under the patronage of a king named
Dhavalachandra, and is considered to be both an independent treatment of and influenced by another ancient collection of stories and fables from India (or Bhārat), The Panchatantra (~600 BCE or much earlier,since the fables have roots in long-lost oral history traditions). The word hitopadesh or hitaopadeśa, is acombination of two root words, hitah and opadesh, and it literally means: words and verses (opadesh oropadeśa) that are beneficial (hit or hitah) to mankind.
2 A shāstra is a collection of findings of and inquiries in a field of study (science, arts, philosophy, etc.).
For example, rasāyana shāstra refers to chemistry, ganita shāstra refers to mathematics, khagola shāstra
refers to astronomy, artha shāstra refers to economics and/or political science, chhanda shāstra refers tostudy of poetry and its structure, and nāTya shāstra refers to the art and science of theater, among others.

papers are reviews and others are new investigations, and it is hoped that the readers
will find the presentations and results of different inquiries to be both insightful andpointers to new directions and quests of hitherto unanswered questions.
Widely disseminating scientific information (of course, with the implied assumption that written work will be read and assimilated), connecting community members
in order to create intellectual synergy, and guiding others have been passionate lifelong
endeavors for Art Bergles. On a very personal note, he was instrumental in connecting
me with Professor Frank Kreith, which led me on another journey of learning. This
collaboration resulted in the co-authorship of the 7th edition of his classical (and perhaps the first) heat transfer textbook, Principles of Heat Transfer (Cengage Learning,Stamford, CT, 2011). A particularly happy reunion event was a photo-op celebration(Fig. 1) during the promotion of this book at the American Society of MechanicalEngineers (ASME) International Mechanical Engineering Congress and Exposition(IMECE) in November 2011.

It is believed, as has been succinctly and poetically articulated in the following
verse in Sanskrit (which is also taken from one of the many ancient Hindu texts, orshāstras) that knowledge acquisition or learning is made up of four synergistic parts:āchāryāt pādamādatte, pādam shishyah swamedhayā |sa-brahmachāribhyah pādam, pādam kālakramena cha ||Journal of Enhanced Heat Transfer

Commemorating the Life and Times of Art Bergles

In essence, one-fourth is acquired from the āchārya (guru or teacher), one-fourthfrom the inquiring application of one’s own intellect, one-fourth from assimilationand interaction with peers, and one-fourth from passage of time and experience. And
who is an āchārya? One whose values and conduct (ācharana) are worth emulating,and thus we imbibe learning from the role model of an āchārya. For me, and I believe
for many others in our community, Art Bergles embodied and eminently exemplified
all this; he was indeed a selfless mentor, sage, both a teacher and a peer, and a friend.
It is ardently wished that Art’s legacy will be celebrated by not only the readings ofthe published work in these multiple issues of the memorial volume of the Journal of
Enhanced Heat Transfer, but also that they will invigorate future advancements in thefield of enhanced heat and mass transfer.
