A. H. Zewail. Voyage Through Time: Walks of Life to the Nobel Prize, American University in Cairo (AUC), Cairo, 2002; so far in 17 languages and editions: English, French, German, Spanish, Romanian, Hungarian (in press), Russian, Arabic, Chinese, Korean, Bahasa Malaysian, Indonesian, Hindi; and 4 editions. For detailed reviews of this book see, for example, articles written by W. Sibbett, B. V. McKoy and C. A. McKoy, and M. Chergui.

For this journey on the road to the Nobel prize, I have been asked several times to write a biography, or at least a biographical summary of my life. I declined these invitations. I was of the opinion that a traditional biography should represent a lifetime of work and experience and much effort and time are needed to do it well. In July of 1997 while on a trip to Cairo this strong feeling softened to a more moderate one. I was stimulated to ask a few questions by two books I was reading, one titled A History of Knowledge by Charles van Doren and the other Making Waves by Charles Townes. How did I acquire knowledge? Why did I become a scientist? What are the forces that have determined the walks of my own life? What are the meanings of faith, destiny, and luck? In the attempt to answer such complex questions, I began to sketch my thoughts....

D. L. Smith. Coherent Thinking, Eng. Sci. 62, 7 (1999)

At 5:40 in the doggone morning on Tuesday, October 12, Ahmed Zewail got a phone call. But it wasn't a wrong number or a particularly ambitious aluminum-window salesman—it was the Royal Swedish Academy of Sciences informing him he had won the 1999 Nobel Prize in chemistry. The citation reads, in part, that Zewail "is being rewarded for his pioneering investigation of fundamental chemical reactions, using ultra-short laser flashes on the time scale on which the reactions actually occur"...

A. H. Zewail. Franklin's Vision, Speech at the Annual General Meeting of the American Philosophical Society in celebration of the Franklin Tercentenary, Philadelphia, Pennsylvania, April 27, 2006.

On this special occasion of the Tercentenary, I am especially delighted to speak in honor of a polymath and an American icon, Benjamin Franklin. Since his death in 1790, Franklin has been revered, memorialized, and made into an educational, financial, and political icon. Through his collective work this sage has climbed to the apex of human endeavor in the sciences, public service, and statesmanship in international relations. Such great heights for a man of wit and wisdom are reached by very few in the world, both then and now...

A. H. Zewail. Light and Life, Ninth Rajiv Gandhi Science and Technology Lecture, Rajiv Gandhi Institute for Contemporary Studies, Bangalore, India, October 17, 2002.

Scientific research is the subject of this lecture, but I wish to focus here on one of its pillars—the value of curiosity-driven research and its impact on our life, the life of the "haves" and "have-nots". For this scientific endeavour, I will demonstrate my point from the study of one phenomenon that has occupied the thinking of humans throughout history—it is the phenomenon of light. What is light?

A. H. Zewail. Time's Mysteries and Miracles: Consonance with Physical and Life Sciences, Albert Einstein Public Lecture, IIT, New Delhi, India, October 22, 2002.

Ever since the dawn of history, humans have been the benefactors of time's miracles, but at the same time they have been baffled by time's mysteries. More than six millennia ago, the philosophy and measurement of time occupied the minds of scholars in the land of Bibliotheca Alexandrina, and, even today we struggle with the meaning of time. In this overview, I present some concepts and techniques developed in the science and technology of time, and an exposé of some of the mysteries and miracles that are in harmony with physical and life sciences...

A. H. Zewail. It is Possible, One Hundred Reasons to be a Scientist, 2nd ed., ICTP, Trieste, 2005, p. 260.

On the banks of the Nile, the Rosetta branch, I was born in Damanhur, the "City of Horus", only 60 km from Alexandria. In retrospect, it is remarkable that my childhood origins were flanked by two great places—Rosetta, the city where the famous Stone was discovered, and Alexandria, the home of ancient learning...

J. S Baskin and A. H. Zewail. Freezing Atoms in Motion, J. Chem. Educ. 78, 737 (2001).

The concept of the atom, proposed 24 centuries ago and rejected by Aristotle, was born on a purely philosophical basis, surely without anticipating some of the 20th century's most triumphant scientific discoveries. Atoms can now be seen, observed in motion, and manipulated...

J. S. Baskin and A. H. Zewail. Freezing Time—In a Femtosecond, Sci. Spectra 14, 62 (1998).

With ultrashort pulses of laser light, it has become possible to observe physical, chemical and biological changes with a resolution of femtoseconds, 15 orders of magnitude faster than the human heart beat, reaching the scale of atomic motion, spatial and temporal...

A. H. Zewail. The Birth of Molecules, Sci. Am. 263, 76 (1990).

In 1872 railroad magnate Leland Stanford wagered $25,000 that a galloping horse, at some point in stride, lifts all four hooves off the ground. To prove it, Stanford employed English photographer Eadweard Muybridge. After many attempts, Muybridge developed a camera shutter that opened and closed for only two thousandths of a second, enabling him to capture on film a horse flying through the air. During the past century, all scientific disciplines from astrophysics to zoology have exploited high-speed photography to revolutionize understanding of animal and mechanical motions that are quicker than the eye can follow...

M. Gruebele and A. H. Zewail. Ultrafast Reaction Dynamics, Phys. Today 43, 24 (1990).

With new laser techniques and with gas phase and molecular beam experiments, it is now possible to determine the ultrafast motion in isolated chemical reactions: chemistry on the 10^-13-second time scale...

A. H. Zewail. Laser Selective Chemistry: Is It Possible?, Phys. Today 33, 27 (1980).

With sufficiently brief and intense radiation, properly tuned to specific resonances, we may be able to fulfill a chemist's dream, to break particular selected bonds in large molecules...

D. Baltimore and A. H. Zewail. We Need a Science White House, Wall Street Journal, April 17, 2008, p. A18.

Tomorrow Hillary Clinton, Barack Obama and John McCain should have been going toe-to-toe in a televised science debate. All three were invited by a bipartisan group of Nobel laureates and other scholars called ScienceDebate 2008 to step on stage at the Franklin Institute in Philadelphia and explain how they will ensure that America continues to dominate the sciences. Leading in scientific research and advancement is an essential element to our future prosperity, health and national defense...

A. H. Zewail. We Arabs Must Wage a New Form of Jihad, Independent, August 24, 2006.

The cataclysmic wars in Lebanon, Palestine, and Iraq have uncovered the reality of Arab unity and plight, and the collective conscience of international society. It is abundantly clear that the Arab people must themselves build a new system for a new future. The current state, as judged by a low GDP, high level of illiteracy, and deteriorating performance in education and science, is neither in consonance with their hearts and minds nor does it provide for their political, economic, and educational aspirations...

A. H. Zewail. The West and Islam Need not be in Conflict, Independent, October 24, 2006.

Five years after September 11, we must ask, can western wars solve the so-called global conflict with the Islamic world? The answer, in my opinion, is no. A far better state of world peace would be achieved if the West would make a serious commitment to the just resolution of conflicts, and be genuinely involved, using a fraction of war costs, in building bridges to progress and peace with an understanding of the profound role of pride and faith in the lives of Muslims...

A. H. Zewail. The Future of Our World, 5th U Thant Distinguished Lecture, United Nations University, Tokyo, Japan, April 15, 2003.

Over the last century, our world has experienced at times a "beautiful age" with promises of peace and prosperity, but then some imposing forces changed the entire landscape. History reminds us of recurrences, and the current state of the world is not so different that we may ask—what political and economic forces cause such disorder in a world seeking prosperity through globalization and revolutionary advances in technology? Here we will address the need for a rational world vision that must take into account developments in the population of the have-nots and dialogues of cultures. It is a vision of economic, political, religious, and cultural dimensions in world affairs. Only with such a vision can we shape a bright future for our world...

A. H. Zewail. Dialogue of Civilizations: Making History Through a New World Vision, UNESCO Public Address, Paris, France, April 20, 2002.

The 2002 UNESCO conference, "Science et la quête du sens" in Paris, was devoted to science and the quest for meaning; the English title, "Science and the Spiritual Quest", emphasizes the spiritual dimension, a realm beyond science. Similarly, this chapter, which is based on my lecture given at the conference, is concerned with dimensions beyond science—our human existence in civilizations and cultures that may or may not be in a state of clash...

A. H. Zewail. Science in the Developing World, TWAS Newslett. 14, 23 (2002).

I am pleased to have this opportunity to share with you some personal reflections on current issues which I believe may well be at the core of world peace and stability. Science education and development through science are the subject of my presentation, and I thought I would use my personal journey through two cultures, one currently developing and the other developed, to address issues of concern and what should be done to achieve progress...

A. H. Zewail. Science for the Have-Nots, Nature 410, 741 (2001).

Only a fifth of the population enjoys the benefit of life in the 'developed world', and the gap between the haves and have-nots continues to increase, threatening stability. According to the World Bank, of the 6 billion people on Earth, 4.8 billion live in developing countries, 3 billion live on less than US$2 a day, and 1.2 billion live on less than $1 a day, which defines the absolute poverty standard; 1.5 billion people do not have access to clean water...

The Ahmed Zewail Foundation for Knowledge and Development was established through the American University in Cairo as a non-profit, non-political organization with the purpose of disseminating useful knowledge. The Foundation currently provides prizes for young people who "demonstrate extraordinary commitment to the pursuit of scientific inquiry and the affirmation of humanistic values". In addition, at the Opera House one prize is given annualy for outstanding achievements and creativity in the arts.
