Isaac Elishakoff. Isaac Elishakoff is an Israeli-American engineer who is Distinguished Research Professor in the Ocean and Mechanical Engineering Department in the Florida Atlantic University, Boca Raton, Florida. He is a figure in the area of mechanics. He has made several contributions in the areas of random vibrations, solid mechanics of composite material, semi-inverse problems of vibrations and stability, functionally graded material structures, and carbon nanotubes.

He has over 610 journal papers,  Authored, co-authored, edited, or co-edited 32 books  and has given over 200 national and international talks at conferences and seminars.

His selected lectures on (a) Elastic Stability, (b) Vibration Syntheses and Analysis and (c) Intermediate Strength of Materials are available on the internet.

In 2024, Elishakoff has been selected for the world-renowned "Theodore von Kármán Fellowship". The Kármán Fellowship is an award established in 2005 by the Aachen University of Technology (RWTH Aachen) in Federal Republic of Germany to honor the work of the physicist and engineer Prof. Theodore Von Karman (1881-1963) world renowned aeronautics expert and first director of the Guggenheim Aeronautical Laboratory at the California Institute of Technology. Each year, world-class scholars in the field of science and technology are selected and supported through this fellowship. Elishakoff's host was the Department of Continuum Mechanics. Prof. Elishakoff gave two presentations : (1) "Resolution of the 20th century conundrum in Elastic Stability", and a public lecture (2) "Scientific and Personal Stories about Theodore Von Kármán, Stephen Timoshenko, Paul Ehrenfest, and Walter Vincenti."

In 2021, Elishakoff received the Blaise Pascal Medal in Engineering from the European Academy of Sciences, “to recognize an outstanding and demonstrated personal contribution to science and technology and the promotion of excellence in research and education.” He was simultaneously elected as a Fellow of the European Academy of Sciences. At the award ceremony he lectured on “Uncertainty Analysis in Engineering: From Blaise Pascal and Pierre Fermat to Modern Times.”

Career 
Elishakoff was the Frank M. Freimann Visiting Chair Professor, at the University of Notre Dame, United States in 1985/86 and Henry J. Massman Jr. Visiting Chair Professor, at the same university in 1986/87.

He became a Fellow of American Academy of Mechanics, in 1991 ("For outstanding achievements and pioneering contributions in random vibrations”.) and was Visiting Professor, Sapienza University of Rome, Rome, Italy in 2005, 2010, 2017.

He is a Foreign Member of the Georgian National Academy of Sciences (“For seminal contributions to the theoretical and applied mechanics”) since 2010, a Member of the European Academy of Sciences and Arts since 2011 and a Fellow, ASME  since 2011.

He received the Worcester Reed Warner Medal from the American Society of Mechanical Engineers in  2016.; established in 1930, it is one of the society awards with the longest history. In 2019 he was awarded the William B. Johnson Inter-Professional Founders Award “In recognition for a lifetime achievement of accomplishments in applied mechanics research and instruction which affect world-wide advancement of business, culture, and learning”, by the Engineers Council.

Passion for Teaching: Response to Stephen Colbert 

Here is a quote on the quadratic formula from I Am America (And So Can You!) by Stephen Colbert:

“Let’s try a little experiment. Look at this equation:

What you are feeling right now, is your body rejecting an idea that is trying to make you learn it. Don’t fight the confusion. That’s just your mind scabbing over in a desperate attempt to protect you from that unnatural commingling of numbers and letters up there. You can’t add it, and you can’t read it. Useless.”

Elishakoff wrote an extensive response to Mr. Colbert’s statements. Likewise, he described differential equations of love in order to promote  love of differential equations by undergraduate students. As of December 1, 2024, these papers have been downloaded 18,087 times. With J. N. Reddy, Elishakoff has written on solving quadratic equations without resorting to quadratic formula. He also writes educational papers

History of Science

Elishakoff is interested in the history of science. In recent years he published several articles about Stephen P. Timoshenko (1878-1972), author of numerous textbooks In applied mechanics. The article “ Stepan Prokofievich Timoshenko and America” became one of the most downloaded articles of The Journal of Applied Mathematics and Mechanics, also known as Zeitschrift für Angewandte Mathematik und Mechanik or ZAMM, during years 2018/19.
