Alastair Graham Walter Cameron was born in Winnipeg on June 21, 1925, and died in Tucson on October 3, 2005. As a boy his interests ran to science fiction and away from sports. His father was head of the biochemistry department at the Manitoba Medical College; at the age of four Cameron addressed all men as “Doctor,” which he later said was an early example of forming a hypothesis based on limited data.His mother raised him by herself. Working his way through a private high school he became a bookie, taking bets from fellow students, and did quite well. In about 1941 he made a bet with a classmate that man would land on the Moon by the year 1970. Years later the classmate asked Cameron how he had known when the Apollo Program would take place. He replied that he had extrapolated the speed of transportation to the time when that speed would exceed that needed to escape from the Earth.He majored in math and physics at the University of Manitoba, and for his physics Ph.D. at the University of Saskatchewan, where he devised a new method to determine nuclear cross sections. He went on to apply nuclear physics to the origin of the chemical elements, or nucleosynthesis, in stars. In 1955 he married Elizabeth “Betsy” MacMillan. Betsy called Cameron “Alastair,” but in the scientific community he was known only as “Al.”After the Ph.D., Cameron spent two years at the Ames Research Center of the U.S. Atomic Energy Commission. While there he read that the astronomer Paul Merrill had observed a feature in the spectrum of a red giant star that corresponds to the chemical element technetium (Tc). Technetium has no stable isotopes; it was discovered in 1937 only after bombarding molybdenum with energetic particles; hence its name, derived from the Greek for “artificial.” Given the fact that technetium decays rapidly into other elements, Cameron reasoned that it must have been created in the star where Merrill found it. Cameron found this discovery “very exciting” because it provides a clue to the origin of the heavy elements in the Universe. Having never studied astrophysics before, Cameron immersed himself in the literature. In 1954 he relocated to the Chalk River Laboratory of the Canadian Atomic Energy Project, where he calculated cross sections for the many nuclear reactions that occur in the interiors of stars when the temperature is high enough for collisions between charged nuclei to overcome the electrical repulsion between them.The temperature at the center of the Sun is 14 million degrees, high enough to allow the conversion of hydrogen into helium, but not high enough for the reactions that ultimately lead to the creation of elements as heavy as Tc, that require hundreds of millions of degrees.While Cameron was working on nucleosynthesis, other theorists calculated that the Sun would run out of hydrogen in 5 billion years, at which time the temperature in its core would begin to rise, and the Sun would become a red giant star of the type that Merrill observed to contain Tc. Surprisingly, when stars run out of one nuclear fuel, their cores get hotter, not cooler, and then new fuels that react only at higher temperatures kick in. In red giant stars the helium produced earlier is reacting to form even heavier elements.Cameron predicted what elements are produced and in what quantities. He found that indeed technetium is produced along the way, explaining Merrill’s observation. In order to be found in the atmospheres of the Sun and other stars, and in solid bodies such as planets and meteorites, new elements have to first be ejected from the parent star into space where they contaminate interstellar matter destined to form new generations of stars and planets. Thus the full understanding of nucleosynthesis involves the formation of stars and planets, as well as the ejection of heavy elements into space by red-giant winds and supernova explosions. Undaunted by the challenge, Cameron plunged into a full range of theoretical astrophysics.Cameron published his papers on nucleosynthesis in 1957. Experts attribute the birth of the field of nuclear astrophysics to those papers, together with one by a group at Caltech led by William Fowler published the same year. Fowler, an experimentalist, won the Nobel Prize in 1983 for his work in the field, and in his Nobel Lecture credited the independent work of Cameron.In 1961 Cameron moved from Chalk River to the newly formed Goddard Institute for Space Studies in New York City. There he supervised graduate students at Columbia, New York University, and Yale. He taught regularly at Yale, where his students compiled his notes into a monograph that is highly regarded, but unfortunately, was never published. In 1973, upon the founding of the Harvard-Smithsonian Center for Astrophysics (CfA) at 60 Garden Street, Cameron was appointed to a professorship in the Department of Astronomy at Harvard. He also accepted a position as associate director of CfA for Planetary Science, a field to which his interests were increasingly turning because of the continuing discoveries of anomalous abundances of isotopes in meteorites. His model of the Solar Nebula, a disk of gas and dust formed at the time of the origin of the Sun 4.5 billion years ago, provides quantitative temperatures that theorists use in their studies of planet formation.During this period, Cameron is reported to have given a seminar at Caltech covering the entire history of the Sun and planets, from the collapse of an interstellar cloud to the coagulation of dust to form the solid cores of the planets. When asked what he did on the seventh day, Cameron replied, “I rested.”An important result of Cameron’s work was his conclusion that the main product of the buildup of the observed high abundance of the elements near iron in the periodic table is not iron per se, as had been assumed, but radioactive nickel 56. His idea was verified many years later by a NASA spacecraft.In 1982 Cameron became the chair of the Space Science Board of the National Academy of Sciences, which advises NASA on its science program, and at Harvard he served six years as chair of the Department of Astronomy. During this period he also organized annual conferences to bring together astrophysicists and planetary scientists to enhance collaborations between their different specialties.He then decided to attack a long-standing theoretical problem in planetary physics: the origin of the Moon. The Apollo Program had found that unlike the Earth, the Moon has no iron core, but is composed solely of the same material as the mantle of the Earth. At the time theorists could not explain this fact. Cameron proposed that the Moon formed from a disk of debris orbiting the Earth, much as the Solar Nebula orbited the Sun. But where could the debris have come from? Cameron proposed that it was material ejected from Earth’s mantle when a Mars-sized body collided with the Earth early in the history of the solar system. That would explain the Moon’s composition, but how would the debris reach the distance of the Moon? Cameron attacked this problem head on, acquiring faster computers for his office in order to model the collision event. He finally succeeded in showing that such a collision would result in a disk of the correct mass, as well as the angular momenta of the Earth and Moon that are observed today. Cameron’s theory is now the accepted one for the origin of the Moon.Cameron received honors from many scientific societies, among them the Petrie Prize of the Canadian Astronomical Society, the NASA Distinguished Service Medal, the Smith Medal of the National Academy of Sciences, the Hess Medal of the American Geophysical Union, the Leonard Medal of the Meteoritical Society, the Bethe Prize of the American Physical Society, and the Henry Norris Russell Lectureship of the American Astronomical Society—the highest honor an astronomer can receive.Upon his retirement from Harvard in 1999, Cameron accepted an appointment at the Lunar and Planetary Laboratory of the University of Arizona in Tucson. There he and Betsy lived in the Academy Village, a non-profit organization devoted to life-long learning. Sadly, Betsy, his loving wife of forty-six years, died in 2001; they had no children. Those of us who were lucky enough to know Al Cameron well remember him as an exceptionally talented and dedicated scientist, a wise counselor, and a witty person. Few are those who cross one’s path with all of these qualities; Al Cameron was one of them.Respectfully submitted,Alexander DalgarnoJames MoranDimitar SasselovPatrick ThaddeusFriedrich ThielemannGerald WasserburgJohn WoodGeorge Field, Chair

The Senator Versus Coal FacebookTwitterLinkedInEmailPrint分享The coal industry — responsible for much of the CO2 pollution driving climate change — is dying, and State Senator Loni Hancock, D-Berkeley, wants to help bury it. Hancock, whose district encompasses much of the East Bay, from Rodeo to San Leandro, has spent the last half year drafting legislation designed to prevent millions of tons of coal from being transported by train through the East Bay and exported from a marine terminal that is to be built in Oakland near the foot of the Bay Bridge. Hancock also wants to block any future coal export schemes in the state.Hancock made a last ditch effort to convince Utah’s lawmakers that subsidizing an Oakland coal terminal is unwanted and risky. “I strongly oppose your bill to invest $53 million in Utah taxpayers’ money to build a coal-export terminal in California,” Hancock wrote in a March 2 letter to Utah Senator Adams. “Environmental groups from Oakland and the Bay Area strongly oppose the transport of coal and are working together to stop the project.”Hancock also informed Adams of her four anti-coal bills that will be considered by the California Senate in April. “I would think that Utah residents would also question whether their hard-earned tax dollars should be going to build a railroad and port terminal in another state instead of promoting sustainable economic development in Utah,” she wrote.Some Utah lawmakers raised Hancock’s criticisms during debates in the Senate and House of Representatives last week, but Adams’ $53 million coal subsidy was approved by both houses and will likely be signed by Governor Herbert.Hancock said the use of public money is a bad investment in a “dying industry” and can only result in environmental damage and economic losses. She said it appears that the coal industry is attempting to use public money to stay afloat, because private investors have all but abandoned coal.“Institutional investors are pulling out of coal,” said Tom Sanzillo of the Institute for Energy Economics and Financial Analysis, a think tank that promotes renewable energy development. “The industry isn’t collapsing, it has collapsed.”
Critics argue the law discriminates against Muslims and violates the spirit of India’s secular constitution.Hundreds of thousands of people have taken part in protests since December.Earlier this week, the office of the UN High Commissioner for Human Rights said it intended to approach India’s Supreme Court about the citizenship law. Topics : Iranian Supreme Leader Ayatollah Ali Khamenei urged India on Thursday to “confront extremist Hindus” and “stop the massacre of Muslims”, adding to the international fallout over deadly Hindu-Muslim violence in New Delhi.At least 44 people were killed and hundreds injured in the worst communal riots in the Indian capital in decades, triggered by clashes between supporters of a new citizenship law and those against it.”The hearts of Muslims all over the world are grieving over the massacre of Muslims in India,” Khamenei said in a tweet in English, just days after New Delhi rebuked Iran’s foreign minister for commenting on the same issue. “Iran condemns the wave of organized violence against Indian Muslims,” Foreign Minister Mohammad Javad Zarif tweeted on Monday, in response to which New Delhi summoned the Islamic Republic’s ambassador and lodged a protest.”We do not expect such comments from a country like Iran,” ministry spokesman Raveesh Kumar said in a statement later.The citizenship law provides non-Muslims from Afghanistan, Bangladesh and Pakistan a fast track to Indian citizenship.Prime Minister Narendra Modi’s Hindu nationalist government says this is required to help minorities from those mainly Muslim countries.
“The OPSG is in a unique position to help EIOPA and other European institutions to reach the best possible outcomes.”Leppälä is the second secretary general of PensionsEurope to chair the OPSG, following Chris Verhaegen’s term as the group’s inaugural chair, when the organisation was known as the European Federation for Retirement Provision. The OPSG, which met on 28 April for the first time since 21 new members were named, also elected Bernard Delbecque as deputy chairman during its meeting, the EIOPA press office confirmed to IPE.Delbecque was appointed to the OPSG earlier this year.He is director of economics and research at the European Fund and Asset Management Association (EFAMA), which in the past has been a propronent of a pan-European personal pension product – an idea now championed by the European Commission as part of its Capital Markets Union proposals. Matti Leppälä, secretary general at PensionsEurope, has been elected chair of the European Insurance and Occupational Pensions Authority’s (EIOPA) pension stakeholder group (OPSG), succeeding Philip Shier.Leppälä, who has been with the European industry group since 2011, was previously the OPSG’s deputy chair, serving under Benne van Popta and Shier, following the former’s resignation mid-term in 2015.“I am honoured to chair the OPSG for the coming term of two and a half years,” Leppälä said in a statement.“The role of occupational pensions and other private pensions is increasingly important for good pensions in Europe.

Facebook Twitter Google+ Published on April 16, 2017 at 10:33 pm Contact Andrew: email@example.com | @A_E_Graham A steady din carries through Drumlins Tennis Center on game days. The faint hum from dozens of fluorescent lights, the chatter of fans and coaches and the steady rhythm of “thwacks” coming from each court as a rally ensues all contribute to the noise.When a rally subsides and a point is won, it’s often punctuated by the hollers and screams of a Syracuse player, especially when they speak multiple languages.“Half the people on the team have a specific thing they always say,” said Gabriela Knutson, a Czech Republic native.Six different players for Syracuse (7-12, 4-8 Atlantic Coast) are fluent in at least one language other than English. That offers players a unique avenue to express emotions and vent aggression without fans, opponents, and most importantly, officials, catching on to what they are saying. Three players — Knutson, Anna Shkudun and Masha Tritou — admitted that they use the mask of other dialects to let the occasional, or frequent, curse word fly.“It just feels great you know,” Greece native Tritou said. “I’m taking it out of my system and I just feel more relaxed after that, and I’m like, ‘OK, now, play.’”AdvertisementThis is placeholder textOf all the multilingual players, Shkudun is the most vocal. The Ukrainian native alternates between English, Russian, and Ukrainian. It gives her a chance to vent her frustrations of missing a shot long or planting a return in the net without letting the whole venue know quite what she’s saying.But she knows it’s not entirely a secret.“It’s cool that no one really understands,” Shkudun said, “but at the same time, some people can guess.”While Shkudun, Tritou and Knutson all admitted to cursing, none divulged what they say.Codie Yan | Staff PhotographerWhat they all did convey is even though they can say almost whatever they please, it is almost never directed at their opponent. Cursing is reserved for themselves. Tritou does it often, Knutson and Shkudun each a little bit here and there. Libi Mesh, who grew up in Israel, said she tries not to, and checks herself carefully when she feels emotions are reaching a boiling point.“I try not to say bad stuff on the court,” Mesh said. “… I could, but I try to avoid it.”Knutson is far less worried about controlling her language, and she knows that there are many things said in Czech that would otherwise have her holding her tongue in English.“I think it comes naturally at that point,” Knutson said.Besides the obvious ability to curse, players often bellow far more tame, words and phrases.Of all the things players shout, Shkudun’s “v kort,” which is roughly Russian for “play inside the court,” is probably the most specific.One phrase that bridges all speech patterns and cultures on the team is the classic, “come on!” Shkudun and Tritou can be heard yelling it in Russian as “davai” while Mesh opts between Russian and the Hebrew alternative of “kadima.” Tritou — who speaks Dutch, Greek, Russian and English — will occasionally blurt it out in Dutch as “kom op.”Knutson often shouts “legs” in Czech to herself, accompanied by an open palm to her thigh. Her mother, Ilona, used to urge her on as a child, encouraging use of her lower body. Knutson’s Czech iteration of legs, “nohy,” is closely related to Shkudun’s Russian rendition of “nogi.” Mesh’s Hebrew version, “raglaim,” stands out.“Whatever happens,” Mesh said, “whatever language comes out, it’s what comes out.”SU head coach Younes Limam stresses body language with his team, and their actual language plays a role in that. Limam want his players to mask any nerves or discomfort by getting fired up and giving an occasional yell or shout. Similarly, if a player wins a big point, he wants them to celebrate it and own the moment.As for the swearing, Limam doesn’t get involved.“I try not to know,” Limam said. Comments
