Essay About Ahmed Zewail Death


Ahmed Hassan Zewail was born on 26th, February 1946 in Damanhour, and raised in Disuq. He is an Egyptian scientist and he is also a holder of the American nationality. He is a great hero which the entire humanity has rewarded him by choosing him for the Nobel prize, He had won the Nobel prize in chemistry on 1999 for his work in Femtochemistry*: Atomic-Scale Dynamics of the Chemical Bond Using Ultrafast Lasers. He is a professor in California Institute of Technology. He is the Linus Pauling Chair Professor Chemistry and Professor of Physics.

* Femtochemistry is the science that studies chemical reactions on extremely short timescales, approximately 10–15 seconds (one femtosecond, hence the name).

I admire this person because he has made a name for himself that all humanity will remember as the founder of The FemtoChemistry science. He became a great name to people in a short period of time, though he was still young he didn't spend his free time playing and hanging around like most boys his age, no, he practiced science. He lived through hard times but it was all painless and he never felt it, because he was honoured at the end with the Nobel prize on 1999.

He is just a simple Egyptian who had dreams to be great. And now he is great as he reached President Barack Obama's Presidential Council of Advisors on Science and Technology (PCAST). The council will talk about education, science, defense, energy, the economy, and technology.

Professor Ahmed Zewail. (

His family's dream was that he recieves a high degree abroad and return to become a university porfessor. On the door of his study room, a sign was placed reading "Dr.Ahmed", though he was still far from a doctor. his father lived to see that day all his life.

His uncle Rizk was a special character Zewail's life, He learned much from him: an appreciation for critical analyses, an enjoyment of music, and of intermingling with the masses and intellectuals alike; he was respected for his wisdom, financially well-to-do, and self-educated.

Zewail's interests were focused, reading, music, some sports and playing backgammon. He loved music, especially Um Kulthum, an Egyptian singer that rocked the world. She had a magical voice that was always in the background while he was studying mathematics and chemistry. In America, the only music He has been able to appreciate on this level is classical and some jazz. Reading was and still his real joy.

He graduated from the University Of Alexandria with a bachelor's and MS degree. He completed his PhD in The United States, at the University Of Pennsylvania. In 1999, Zewail became the third Egyptian to receive the Nobel Prize, before him was president Anwar Al-Sadat (1978 in Peace) and Naguib Mahfouz (1988 in Literature). He also received the Wolf Prize in Chemistry (1993) by the Wolf Foundation, the Tolman Medal (1997), and the Robert A. Welch Award (1997).

My hero receiving his Nobel prize. (

He was one of the original editors of the highly acclaimed Encyclopedia of Analytical Chemistry, which provides a much needed professional level reference work for the 21st Century. The Encyclopedia is the most comprehensive analytical chemistry reference available, covering all aspects from theory and instrumentation through to applications and techniques.

In 1999, he received Egypt's highest state honor, the Grand Collar of the Nile. In the late 1980s,it was impossible to study events that constitute a reaction. However, Zewail was able to view the motion of atoms and molecules using a method based on new laser technology capable of producing light flashes just tens of femtoseconds in duration.

Ahmed Zewail is my hero, he is a simple -but still great- person that worked hard all his life to rest in the end as one of the world's most famous professors. He has a great mind that inspired me to not only become Hajar Ahmed, but try and do my best to be Dr. Hajar Ahmed.

Ahmed H. Zewail, in full Ahmed Hassan Zewail, (born February 26, 1946, Damanhur, Egypt—died August 2, 2016, Pasadena, California, U.S.), Egyptian-born chemist who won the Nobel Prize for Chemistry in 1999 for developing a rapid laser technique that enabled scientists to study the action of atoms during chemical reactions. The breakthrough created a new field of physical chemistry known as femtochemistry. Zewail was the first Egyptian and the first Arab to win a Nobel Prize in a science category.

After receiving B.S. (1967) and M.S. (1969) degrees from Alexandria University, Zewail attended the University of Pennsylvania, where he earned a doctorate in 1974. Two years later he joined the faculty at the California Institute of Technology, and in 1990 he was selected as the school’s first Linus Pauling Professor of Chemical Physics. Zewail also served as a visiting professor at a number of institutions, including Texas A&M University, the University of Iowa, and American University at Cairo. He founded (2011) Zewail City of Science and Technology, a premier institute of technology in Cairo.

Because chemical reactions last only 10 to 100 femtoseconds (fs)—one femtosecond is 0.000000000000001 second, or 10-15—many believed it would be impossible to study the events that constitute a reaction. In the late 1980s, however, Zewail was able to view the motion of atoms and molecules by using a method based on new laser technology capable of producing light flashes just tens of femtoseconds in duration. During the process, known as femtosecond spectroscopy, molecules were mixed together in a vacuum tube in which an ultrafast laser beamed two pulses. The first pulse supplied the energy for the reaction, and the second examined the ongoing action. The characteristic spectra, or light patterns, from the molecules were then studied to determine the structural changes of the molecules. Zewail’s discovery enabled scientists to gain more control over the outcome of the chemical reaction, and it was expected to have many applications. Zewail also used elements of femtochemistry to invent a 4D electron microscope, with which operators were able to investigate the dynamics of atoms one billion times faster than they could with previous microscopes.

“With femtosecond spectroscopy we can for the first time observe in ‘slow motion’ what happens as the reaction barrier is crossed,” the Nobel Assembly said in its press release announcing Zewail as the winner of the 1999 prize for chemistry. “Scientists the world over are studying processes with femtosecond spectroscopy in gases, in fluids and in solids, on surfaces and in polymers. Applications range from how catalysts function and how molecular electronic components must be designed, to the most delicate mechanisms in life processes and how the medicines of the future should be produced.”
