Georges Charpak, Physics Nobel Winner, Dies at 86
Georges Charpak, who won the 1992 Nobel Prize in Physics for inventing a device to sift through the billions of hurtling subatomic particles liberated by collisions in atom smashers, opening the way for discoveries on the nature of matter, died on Wednesday in Paris. He was 86.
Leif R. Jansson/SCANPIX, via ReutersGeorges Charpak in 1992.
His death was announced by France’s research ministry.
Particle accelerators, popularly known as atom smashers, whip subnuclear particles like protons and electrons to high speeds and then force them to collide. The collisions generate a storm of particles flying in many directions. Some of these short-lived particles have not existed since the Big Bang created the universe nearly 14 billion years ago, and identifying them and charting their behavior have been principal goals of modern high-energy physics.
With his invention, the multiwire proportional tracking chamber, Dr. Charpak vastly improved the ability of physicists to measure and record what goes on inside particle accelerators. Earlier detectors, like the cloud chamber and bubble chamber (which, too, earned Nobels for their inventors) depended on taking photographs of the tracks left by particles as they emerged from collisions.
Dr. Charpak’s chamber, by contrast, used many minuscule wires to capture electric pulses, thus generating vastly more information. The data was instantaneously fed into a computer for interpretation. No longer did scientists have to scan thousands of photographs.
The invention meant that hundreds of millions of particles a second could be sensed, evaluated and recorded. It allowed scientists testing theories to search out the one particle in a billion for which they were hunting.
Two Nobel Prizes were awarded for identifying subatomic phenomena using Dr. Charpak’s device before he received his.
Other physicists used it to earn Nobel Prizes later. Variants of the device now contribute to the $10 billionLarge Hadron Collider put into operation this year at the European Organization for Nuclear Research, or CERN, in Geneva, where Dr. Charpak worked for decades. That project aims to explain the origins of the universe.
Leon Lederman, Dr. Charpak’s former boss at CERN and a winner of the Nobel physics award himself, said in an interview with NPR in 1992 that Dr. Charpak’s instrument worked by very indirect means.
“No one’s ever seen an atom, really,” Dr. Lederman said. Accordingly, he said, Dr. Charpak measured the infinitesimal electric impulses that particles leave as they race through one of his devices. Dr. Lederman compared the phenomenon to hearing a noise in the sky and looking up to see a contrail, then reasoning that an airplane had passed.
In a speech last year, Dr. Charpak (pronounced shahr-PUCK) said he was born on March 8, 1924, not Aug. 1 as officially recorded. His birthplace was a village in Poland that is now in Ukraine.
The family moved to Paris in 1932 when Dr. Charpak was 7. After France surrendered to Germany in June 1940, his family refused to wear the yellow star the Nazis demanded Jews wear. They obtained false identity papers under the name Charpentier.
As a teenager, Dr. Charpak became active in the French resistance to Nazi occupiers and was imprisoned by the pro-Nazi French government in 1943. In 1944, he was transferred to the Nazi concentration camp at Dachau, Germany.
In an article he wrote in 1994, Dr. Charpak said that at the first camp, in France, prisoners took two spoonfuls of the thin broth they received to give to “the weakest and sickest among us.” He wrote, “It was a gesture that gave us a sense of great dignity.”
After the war, Dr. Charpak became a French citizen and earned a bachelor’s degree in mining engineering from the École des Mines, then a Ph.D. from theCollège de France. While pursuing his doctorate, he worked in the laboratory of Frédéric Joliot-Curie, a Nobel Prize-winning physicist.
He joined CERN in 1959 and stayed until his retirement in 1991. He was part of a team that in 1961 determined that a particle known as the muon was not a separate particle of the nucleus, but just a heavy electron. In an interview in 2009, he called this his proudest accomplishment. In 1968, he invented the multiwire proportional tracking chamber, the device for which he won the Nobel.
After winning the prize, Dr. Charpak tried to apply its principles in biology and medicine. One of his first projects was to study electrical impulses in rats’ brains.
His research led to the development of a camera used by NASA to monitor astronauts’ hearts. He developed an X-ray machine that uses one-tenth the radiation of a conventional X-ray. He worked on ways to reprogram cancerous cells so they would no longer be malignant.
Dr. Charpak, who had earlier investigated using radiation to find subterranean minerals, recently developed a radon detector to help predict earthquakes. He was a strong advocate of nuclear power, which provides more than three-quarters of France’s electricity.
When he became alarmed that only 3 percent of French elementary schools introduced their students to science, he started a program in 1996 to encourage students to learn by doing their own scientific experiments. It spread to 12 other countries.
In 2004, Dr. Charpak joined with Henri Broch to write a jaunty, sardonic book titled “Debunked,” deriding ESP, telekinesis, Ouija boards and other phenomena they regarded as pseudoscience. They said astrology was inaccurate because the earth’s axis shifts, making heavenly signs inherently imprecise.
Information on Dr. Charpak’s survivors was not available. Published biographies say he had a wife and three children.
Asked what he planned to do with his prize money in 1992, Dr. Charpak absentmindedly replied that he had hoped to buy a pair of shoes that afternoon, but guessed he would not have time. He soon received gifts of shoes from all over the globe. |

"for groundbreaking experiments regarding the two-dimensional material graphene" Graphene – the perfect atomic lattice
A thin flake of ordinary carbon, just one atom thick, lies behind this year’s Nobel Prize in Physics. Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics.
Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.
Geim and Novoselov extracted the graphene from a piece of graphite such as is found in ordinary pencils. Using regular adhesive tape they managed to obtain a flake of carbon with a thickness of just one atom. This at a time when many believed it was impossible for such thin crystalline materials to be stable.
However, with graphene, physicists can now study a new class of two-dimensional materials with unique properties. Graphene makes experiments possible that give new twists to the phenomena in quantum physics. Also a vast variety of practical applications now appear possible including the creation of new materials and the manufacture of innovative electronics. Graphene transistors are predicted to be substantially faster than today’s silicon transistors and result in more efficient computers.
Since it is practically transparent and a good conductor, graphene is suitable for producing transparent touch screens, light panels, and maybe even solar cells.
When mixed into plastics, graphene can turn them into conductors of electricity while making them more heat resistant and mechanically robust. This resilience can be utilised in new super strong materials, which are also thin, elastic and lightweight. In the future, satellites, airplanes, and cars could be manufactured out of the new composite materials.
This year’s Laureates have been working together for a long time now. Konstantin Novoselov, 36, first worked with Andre Geim, 51, as a PhD-student in the Netherlands. He subsequently followed Geim to the United Kingdom. Both of them originally studied and began their careers as physicists in Russia. Now they are both professors at the University of Manchester.
Playfulness is one of their hallmarks, one always learns something in the process and, who knows, you may even hit the jackpot. Like now when they, with graphene, write themselves into the annals of science.
Graphene is an atomic-scale honeycomb lattice made of carbon atoms.

"for palladium-catalyzed cross couplings in organic synthesis"
Great art in a test tube
Organic chemistry has developed into an art form where scientists produce marvelous chemical creations in their test tubes. Mankind benefits from this in the form of medicines, ever-more precise electronics and advanced technological materials. The Nobel Prize in Chemistry 2010 awards one of the most sophisticated tools available to chemists today.
This year's Nobel Prize in Chemistry is awarded to Richard F. Heck, Ei-ichi Negishi and Akira Suzuki for the development of palladium-catalyzed cross coupling. This chemical tool has vastly improved the possibilities for chemists to create sophisticated chemicals, for example carbon-based molecules as complex as those created by nature itself.
Carbon-based (organic) chemistry is the basis of life and is responsible for numerous fascinating natural phenomena: colour in flowers, snake poison and bacteria killing substances such as penicillin. Organic chemistry has allowed man to build on nature's chemistry; making use of carbon’s ability to provide a stable skeleton for functional molecules. This has given mankind new medicines and revolutionary materials such as plastics.
In order to create these complex chemicals, chemists need to be able to join carbon atoms together. However, carbon is stable and carbon atoms do not easily react with one another. The first methods used by chemists to bind carbon atoms together were therefore based upon various techniques for rendering carbon more reactive. Such methods worked when creating simple molecules, but when synthesizing more complex molecules chemists ended up with too many unwanted by-products in their test tubes.
Palladium-catalyzed cross coupling solved that problem and provided chemists with a more precise and efficient tool to work with. In the Heck reaction, Negishi reaction and Suzuki reaction, carbon atoms meet on a palladium atom, whereupon their proximity to one another kick-starts the chemical reaction.
Palladium-catalyzed cross coupling is used in research worldwide, as well as in the commercial production of for example pharmaceuticals and molecules used in the electronics industry.
Richard F. Heck, American citizen. Born 1931 in Springfield, MA, USA. Ph.D. 1954 from University of California Los Angeles (UCLA), CA, USA. Willis F. Harrington Professor Emeritus at University of Delaware, Newark, DE, USA.
Ei-ichi Negishi, Japanese citizen. Born 1935 in Changchun, China (former Japan). Ph.D. 1963 from University of Pennsylvania, Philadelphia, PA, USA. Herbert C. Brown Distinguished Professor of Chemistry at Purdue University, West Lafayette, IN, USA.
