Chemist And Physicist

Ahmad Hassan Zewail, were a chemist and physicist, born in Damanhur, Egypt, east of Alexandria, in 1946. He studied at Alexandria and Pennsylvania universities, and then moved to California, where he joined the California Institute of Technology in 1976. His research has been in the development of ultra fast lasers and electrons for studies of dynamics in chemistry and biology, and he received the 1999 Nobel Prize for Chemistry for his studies of the transition states of chemical reactions using femtosecond’s spectroscopy.

Femtochemistry is the branch of chemistry in which chemical reactions are detected as they occur and the reaction times are measured. Femtochemistry gets its name from the fact that these times are measured in femtoseconds. One femtosecond is one-millionth of one-billionth of a second. This number is written out as a decimal point followed by 14 zeros and a 1. Scientists believe that no chemical reaction can take place more rapidly than this.What would a soccer match on TV be without "slow motion" revealing afterwards the movements of the players and the ball when a goal is scored? Chemical reactions are a similar case. He was able to follow chemical reactions in the greatest detail has prompted increasingly advanced technology. Ahmed H. Zewail, has studied atoms and molecules in "slow motion" during a reaction and seen what actually happens when chemical bonds break and new ones are created. [pic]
He was the winner of the Nobel Prize for Chemistry because of his find of

    In 1931, he was also elected president of the Institute of Physics. Ernest was offered the chair at Manchester University in 1906 and he did accept the offer, so he moved to Manchester’s new laboratories. Rutherford was luckily enough to be rewarded with the Nobel Prize in 1908, in Chemistry for his work on the transmutation of elements and the chemistry of radioactive material. In the year 1919, Ernest became the Director of the Cavendish Laboratory at the University of Cambridge. Ernest had won the Marlborough Education Board scholarship to Nelson College in 1877. The element Rf was named Rutherfordium in honor of Rutherford. In 1895, Ernest was awarded an Exhibition of 1851 Science Research Scholarship. He was also knighted in the New Year’s Honors list for 1914. Ernest became a member of the Order of Merit in the New Year’s Honors list for 1925. In 1916, Rutherford was awarded the Hector Memorial Medal. He was awarded a research fellowship and when he was awarded it, it allowed him to attend graduate school at University of Cambridge’s Cavendish Laboratory. He had won the only available Senior Scholarship for mathematics. In 1898, Rutherford was rewarded the opportunity to become a physics professor at McGill University in Montreal and he accepted the offer. In 1904, Rutherford had his first book “Radioactivity”…

    At some point, as he recalled in one interview, he was given a textbook on crystallography with a suggestion to read it. “I do not need to read it, I teach this book, I know what is in it” – he replied. But he was eventually distanced by many colleagues and brutally criticized by highly prominent chemists. Despite that, he ultimately stood by his discovery and fought for the…

    Linus Pauling is said to be one of the most significant scientists to have ever lived. Given Pauling’s wide array of accomplishments, ranging from winning the nobel peace prize to solving complex atomic structures, it is easy to see why he has earned the respect of so many in the scientific community. Pauling was born on February 28, 1901 in Portland, Oregon. Even as a young boy he took interest in science; a friend introduced him to a toy chemistry set, and instantly young Linus was hooked and began conducting basic experiments in his basement. Pauling’s interest in chemistry never subsided, in fact he excelled in chemistry throughout his high school and college career (“Biographical Information”).…

    Hassan would be able to tell that the larger skeleton in the sarcophagus was female by the position of the coccyx bone. The coccyx bone at the bottom of the vertebrae points inferiorly in females. This allows for the passage of a baby through the birth canal. The coccyx of a male skeleton would point anteriorly and the opening in the pelvic area would be less than that of a female.…

    Frederick Sanger was first awarded the Nobel prize in Chemistry in 1958 for showing how amino acids join together and form insulin. This discovery lead the way to analyzing any protein in the body. Sanger won his second Nobel prize in Chemistry in 1980 for inventing a way of reading the letters that make up the genetic code. This ended up leading to the development of biotechnology drugs, and was the starting point for the discovery decades later of decoding the whole human genome.…

    In the 1920s, he studied in the area of unified field theories, continuing to work on the quantum theory. Einstein won the Nobel Prize for Physics in 1921 "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect." In the photoelectric effect, electrons are emitted from liquids, solids or gases when they absorb energy from light. Electrons emitted in this manner can be called photoelectrons. Einstein also contributed to statistical mechanics by his development of the quantum theory of a monatomic gas.…
