Ahmed Zewail, the Egyptian inventor

on 2:30 PM
Ahmed Zewail

World femtosecond .. Ahmed Zewail was on 21 October 1999 day unique to Egypt when he got d. Ahmed Zewail, the Nobel Prize in Chemistry to become the first scientist to Egyptian and Arab to win the Nobel Prize in science for his discovery of Vmto again and enter the whole world in a new era not Human not expect to comprehend it.

He was born Zewail Damanhour city and province of the lake in 26 \ 2 \ 1946, was born to the family of an Egyptian simple father was a working observer technical health Desouk, which is the only brother of three girls (ma'am), employee of the City Council Desouk and married her cousin, Salah Zewail and (arrows) education and education, married and living in the center and Glynn (grace) servant of unity in the local Desouk and his family were driven to the success of this young age I have written on the door of his room d. Zell and Ahmad from childhood experiences being a simple household appliances.



Has received Zewail his primary education in the city of Desouk and obtained certificates of primary and junior high school Renaissance and earned a secondary school Desouk where the transfer of his father to work and then joined the Faculty of Science, Alexandria University and he earned a bachelor's in 1967 cum laude with honors and received a Master of Science in spectra in 1969, Ahmed Zewail, and then traveled to the United States to earn a doctorate from the University of Pennsylvania in 1974 and worked during this period, a lecturer and a fellow researcher in the same university and then worked at the University of Caltech in California.



The comment Zewail, saying when I came to America and became a professor in one of the greatest American universities - Caltech - who was appointed in the year 76 after I got my PhD and the degree of Fellow from the University of Berkeley for two years, and in 78 they gave me the degree to stay at the university for a lifetime, while this degree does not grant the holder before the passage of five years, and gave me a university professor does not forget the bowling - was Linus Pauling have earned two Nobel Prizes in chemistry and peace - and this has become one of the youngest scientists are not elected to the Academy of American science and the meaning of this they did not give me a chance only, but also the appreciation of the who helped me scientifically.



Still Zewail currently employs Kostama of physical chemistry at the California Institute of Technology, USA (Caltech) and retains his nationality by Egyptian American citizenship acquired years ago and this award becomes Zewail No. 91 to win the Nobel Prize in chemistry since the establishment of this award, as it is one of the rare scientists who have won this award where the individual has been the practice to involve more of the world to win the award in every branch of science.


He received Zewail before winning a Nobel many degrees has made a Fellow of the University of Berkeley in 1975, then served as an assistant professor of the nature of the chemical at the California Institute of Technology in Pasadena in 1976 until 1978 and then Associate Professor of Chemical Physics in the same institute until 1982, then served as professor of the nature of the chemical 1982 until now and in 1981, was awarded the Outstanding Chemistry Research Corporation (NRC) in Belgium and chosen by the American Society for the nature of the fellowship in 1982. In 1981 won a prize and NASA during the years 1982 and 1984 was awarded the National Foundation of Sciences and was awarded the King Faisal in Nature in 1989 and the award of Hoechst 1990 and in the same year was chosen personal Egyptian-American, as awarded by the University of Oxford Honorary Doctorate in 1991.


In 1993, awarded by the American University in Cairo and a doctorate in science was finally granted a scarf Nile in 1994. D have been nominated. Ahmed Zewail for the Nobel Prize more than once, and Dr. "Ahmed Zewail" a group of devices registered in his name and four scientific books, and more than 250 scientific papers in the areas of laser.



On Tuesday, 21 October 1999 won the Egyptian scientist Dr. Ahmed Zewail, the Nobel Prize in Chemistry to be able to control the movement of atoms within the molecules during a chemical reaction by rapid laser technique has expressed the Royal Swedish Academy of Sciences has been honoring d. Zewail a result of the enormous revolution in the chemical sciences through the pioneering research in the field of chemical reactions and the use of lasers, where a research d. Zewail to the birth of the so-called chemistry Alvmto seconds and the use of cameras to monitor high-speed chemical reactions and quickly Alvmto seconds. Have confirmed the merits of the Swedish Academy awarded the prize to Ahmed Zewail said that this discovery has revolutionized the science of chemistry and related sciences, as the research carried out by allowing us to understand and predict the interactions that task.




But is worth mentioning that Dr. Zewail has entered into the world of laser in a manner adverse to the contrary, everyone was all scientists studying molecules Althamha once each, and they created something new and the properties of a new energy research, but d. Zewail has to know the movement of molecules from birth or Althamha others, and such a process takes only a few seconds and had to be to find a way to intervene to find out what is happening in less than a second using a laser and camera very precise enable Dr. Zewail filming what is happening in chemical reactions record time is a million billionth of a second and the proportion of this period to the equivalent rate per second per second at the age time to 32 million years.




The practical utility of this unit reached by Dr. Zewail back to the possibility of using laser Kmkroscop surgeons shows the picture so that is done in the most critical times in the least period of time and thanks to the research of Dr. Zewail is the development of the factor of time to see things, whether internal or external speed and one millionth of a billionth of a second has been dubbed Alvmto and on this basis possible for the first time to see the invisible particles that cause diseases.


And this is the third time that go where the prize Nobel to Egypt, where he previously obtained by the late President Anwar Sadat for his efforts to bring peace in 1979 and then won by Naguib Mahfouz in literature in 1988 and thus the world's great Egyptian Dr. Ahmed Zewail is the third Egyptian, which raises the his head high, but this time in chemistry. The Egypt celebrated Dr. Zewail at all levels of scientific, literary and artistic, but the Egyptian people's joy by great joy has Henih President Hosni Mubarak on this achievement and sent him a congratulatory telegram soon as he received the Nobel Prize, saying (I am pleased to congratulate one of the sons of Egypt Endowed by winning the Nobel Prize in Chemistry of Egypt will be among the first for the second time in the international arena honors and celebrates their children for starting and educational progress) and the President expressed his wishes for success and excellence Zewail. It also gave him a medal in his honor during a ceremony held in Cairo, was presented his award by Dr. Ahmed Zewail of Egypt, saying (dedicate awards for Egypt, which gave me a lot and will not forget its bid and said that I am proud of the first Egyptian and Arab to win the award in science).



Have been able to d. Zewail to change in the history of science during the filming of a chemical reaction that takes only a moment than a million billionth of a second, change this science of modern chemistry, after peace scientists for the past fifty years the picture approximate developed by the "Max Born in:" Robert Oppenheim, "the so-called moment of transition continues, during which chemical bonds of molecules and associating molecules other material and generates about a new part of any new material and through his creation of the camera Molecular able to portray the process of interaction that occurs at a time such as one second in the film take his 32 million years.



Among the most prominent awards also award "Max Planck" the highest award flag German value, and the award for "Wish" and the award of Benjamin Franklin American, which has already been obtained by Professor Albert Einstein and Madame Curie discovered radium and the Wright Brothers have received Zewail in the city of Houston in the presence of President Carter and President Gerald Ford and more than a thousand guests, dignitaries, as happened Zewail on many honorary degrees and membership of most of the forums and gatherings of the major scientific in the world, and was selected in 1988, is the No. 18 most influential people in the United States and Egypt met with Dr. Zewail very welcome since the eighties.


The increased interest in him and honored in the nineties the generosity of President Mubarak, giving him the Medal of Science in Holiday science, and has issued a mail stamps mail in his name and image of one category of 20 cents and the second category of the pound, and was awarded the University of Alexandria, an honorary doctorate was also his name on the Salon Opera, and in his hometown has held an unprecedented celebration after being awarded the Benjamin Franklin, in the three governorates of Alexandria, Behera, Kafr El-Sheikh province and launched the world's Egyptian name of the lake on a street in Damanhur. On the occasion of honor said Zewail before the audience after he and Sam tribute from President Hosni Mubarak (I'm glad the tribute, this time from the country I was born and that I am one among those who are celebrating through postage stamps bearing the pyramids and Tutankhamen and Queen Nefertiti)
