Alex Dalgarno was a truly exceptional person and scientist. World renowned, he was widely considered the father of theoretical atomic and molecular astrophysics, a field that continues to thrive.Born in London, a fraternal twin, the last of five children of his parents, Alex described his childhood as happy and contented. He especially enjoyed playing soccer. At the end of his secondary schooling, he was invited to try out for the Tottenham Hotspur Football Club in London. This event morphed into the local legend that he then faced a critical decision about whether to pursue a career as a mathematician or professional footballer. He made the right choice and proceeded to gain a bachelor’s degree in mathematics at University College London, capitalizing on his exceptional mathematical skills and prodigious memory. When Alex was about to graduate, a chance encounter in 1947 with Sir Harrie Massey, future chair of the Physics Department there, persuaded Alex to switch to theoretical physics for his graduate work. He seized upon this opportunity to use mathematics to interpret experimental data and thereby to solve interesting physics problems.Alex completed his doctorate in 1951 and was offered his first professional appointment in Belfast by David, later to become Sir David, Bates. At about the same time, rocket flights were making direct observations of the physics and chemistry of the upper atmosphere. To understand these data, Alex developed analytical and numerical techniques for calculating results from an array of radiative and collisional processes. Alex’s forays into perturbation theory, applied to the study, for example, of line broadening and the direct calculation of atomic and molecular polarizabilities became enormously fruitful in those years. Much later, in the 1990s, after Bose-Einstein condensates became feasible, Alex’s methods found new utility in understanding the collisional properties of quantum matter at temperatures near absolute zero.After several long stays in the United States, Alex came permanently to Cambridge in 1967, having accepted a joint offer from Harvard as Professor of Astronomy and from the Smithsonian as Senior Scientist at its Astrophysical Observatory, then and still collocated with the Harvard College Observatory. It took little time for his extraordinary abilities to be appreciated. He was appointed Chair of the Department of Astronomy and served from 1971 to 1976, and, overlapping, Acting Director of the Harvard College Observatory from 1971 to 1973, with the last part of that period also as Acting Director of the Harvard-Smithsonian Center for Astrophysics. Alex also played an important role in the selection of George Field as its first director.Nationally, he was recognized by being appointed in 1973 as Editor of the Astrophysical Journal Letters, a post he served with distinction for almost 30 years. He solved the huge number of problems attendant to that position, always rapidly, justly, and fairly; he opined that not only did he learn a lot of astrophysics in this position but that he “learned still more about people.” Alex also could say more in fewer words than anyone we have ever known. He was both extremely brief and very clear in his communications, oral and written, with all colleagues and mentees.In the mid-1980s, Alex was concerned about the disappearance from the nation’s physics departments of atomic and molecular physics. He decided on a cure: the establishment of an institute for atomic and molecular physics that would train the best and the brightest as postdocs who would then populate physics departments and lead to continued vigor in atomic and molecular physics nationwide. He pursued this idea, gaining adherents, including the National Science Foundation, which funded the center here at Harvard. It has flourished now for almost 30 years.Not only his administrative contributions, but his research productivity, too, kept up a torrid pace; he published papers at an astonishing double-digit annual rate for many decades. In total, he published about 750 peer-reviewed scientific articles spanning his career of over six decades. There was hardly a subfield of aeronomy or astronomy to which Alex’s wide-ranging and fertile mind did not make an important contribution. The external world took notice and showered Alex with awards, such as the Davisson-Germer Prize of the American Physical Society in 1980, the Gold Medal of the Royal Astronomical Society in 1986, the Fleming Medal of the American Geophysical Union in 1995, and the Benjamin Franklin Medal of the Franklin Institute in 2013.Alex was also an enthusiastic and serious athlete for almost all of his life. His passions, after soccer as a youngster, were squash and tennis. Until the Radcliffe athletic center was built, Alex would join a carful of fellow squash players every day at noon and head for the Hemenway gym, where he had a different partner for each day of the week. In the summer, he could usually be found on the Observatory tennis court in the late afternoon. He kept up this pace into his 80s. When puzzled colleagues posed the obvious question—given his enormous administrative load and his deep involvement in research and with students, how could he find time to play so much squash and tennis—his answer was immediate: “I make it my top priority.”Alex’s personal life was more varied. His first marriage to Barbara Kane ended after 10 years; he and his wife had four children, Penelope, Rebecca, Piers, and Fergus, all of whom still live in the United Kingdom. A second marriage, to Emily Dalgarno, in the United States, also ended in divorce. He did have a companion for the last part of his life, Fern Creelan.Alex felt that his true scientific legacy was not his scientific publications, but the more than 100 graduate students and postdocs he had individually nurtured and mentored, who are now mostly very prominent members of the world’s scientific community and furthering the field that absorbed Alex’s passion.The world is unlikely to see the likes of Alex Dalgarno any time soon again.Respectfully submitted,Michael McElroyJames MoranHossein SadeghpourIrwin Shapiro, Chair At a Meeting of the Faculty of Arts and Sciences on Nov. 1, 2016, the following Minute was placed upon the records.

Tag: 上海后花园论坛 Is Creationism on the Decline? If So, Why?
A poll shows decreasing support for Biblical creationism. What factors are causing this?by Dr Jerry BergmanA new Gallup poll shows, for the first time since the poll on this subject began, “a notable decline in the percentage of Americans — including Christians — who hold to the ‘Young Earth’ creationist view that humankind was created in its present form in the past 10,000 years, evolution playing no part.”[i] According to the poll, taken in May, the portion of the American public taking the creation position now stands at 38%. Furthermore, fifty-seven percent accept the “scientific consensus that human beings evolved from less advanced forms of life over millions of years.”[ii] The poll reveals the largest factor in the shift is the jump in the number of Christians who see evolution as God’s way of creating life on Earth and continuing to shape it today.Vol. I (2011)A major reason for the result is, I believe from years of research on the behavior of Darwinians, the ghettoizing and outright persecution of out-of-the-closet persons who have scientific concerns about Darwinism. This has been well-documented in the United States and other countries.[iii] Former Assistant Secretary of State, Kim Holmes, concluded that college administrators “impose limits against Christian and conservative groups, enforcing a double standard of scrutiny” compared to non-Christians and liberals.[iv] For example, University of Michigan PhD Professor Marvin Olasky advises students who accept the creation worldview to face the fact that someMarxists, feminists, and other “-ists” are totalitarians who get pleasure out of making omelets by cracking student eggs. As a student, you’re in a position of weakness, so discretion in this instance may be valorous: Don’t take the course. If you have no alternative, hold on to all your papers and essay tests, and—when confronting totalitarians—tape what goes on in the classroom or in professor/student conferences. If you can’t win internally, you might be able to apply external pressure through conservative journalists.[v]Olasky adds that Christians and conservatives have been saying for decades that “the leftism of most college professors doesn’t matter … This year we’ve found that many have paid attention. The evidence: Socialist Bernie Sanders overwhelmingly won the votes of millennial college graduates.”[vi] Olasky’s new book Passing on the Right: Conservative Professors in the Progressive University in support of his conclusion, published by Oxford University Press, carefully documentsa sad picture of academic bias and conservative cowardice at major universities … quotations from numerous closeted right-of-center professors tell the story. Here are some: “I just bite my tongue. …I just deliberately lie. …I learned I should keep my mouth shut. …It is dangerous to even think [a conservative thought] when I’m on campus, because it might come out of my mouth. …[It’s] exhausting. …You’re not greeted, your greeting isn’t returned in the hall, graduate students are urged not to work with you.”[vii]Vol. II (2016)The fact is “Among academics, the pressure to conform is insidious… a 2015 report of the Foundation for Individual Rights in Education (FIRE) organization finds that policies severely restrict students’ right to free speech at over half of the 437 universities it surveyed.”[viii] The same is true of professors’ freedom of speech. Although exceptions occur, “conservatives who publish still perish.” What can a conservative or Christian professor do to survive?One solution is to hide as a graduate student to get a job, hide as an assistant professor to get tenure, hide as an associate professor to get a full professorship, and hide as a full professor to get an endowed chair. But that’s no way to live—and once you start it’s hard to stop.[ix]In another case, Professors Shields and Dunn quote a literature professor who observed that professorswho hide on the road to a full professorship have “fifteen years of acculturation into cowardice and furtiveness. Suddenly you’re 38 years old and now you’re going to be bold? It doesn’t happen. People … have kids. They’ve got bills to pay.… many [universities] don’t welcome conservative perspectives, and if they did, their socialist colleagues would harass them. Organizations with self-perpetuating boards of directors can readily become corrupt. Most university faculties are self-perpetuating.[x]The antagonism against Darwin Doubters is also clear in an article titled “The Twenty Greatest Blunders in Science in the Last Twenty Years.” One blunder the author lists is not to teach Darwinism as an undisputed fact. She defined evolution as progressing from molecules to man by natural selection favoring variations caused by damage to the genome (mutations). The article starts out by noting that, in 1995 Colorado students would no longerbe tested on evolution, Charles Darwin’s theory that, through an endless series of genetic mutations, we all developed from single-celled organisms. “I believe in divine creation,” said Clair Orr, Colorado’s Chairman of the state’s Board of Education.[xi]She added that, in view ofthe trend of treating all theories of how we got here [i.e. human origins] as equal, Marc Abrahams, of Annals of Improbability Research, has a suggestion: Why not teach the theory of Chonosuke Okamura, a Japanese paleontologist who became convinced that patterns of water seepage in rocks were “mini-fossils” and that life was descended from mini-horses, mini-cows, and mini-dragons. “It’s kind of like forming an evolutionary theory out of cloud formations,” says Abrahams.[xii]My response is that teaching other creation stories is an excellent approach because it allows students to contrast the Genesis account with the other creation accounts. Students will soon understand the enormous contrast between the two creation accounts and realize that Genesis does not contain mythical stories, such as turtles holding up the earth, nor creation by one god tearing another apart and creating the sun, moon and earth from the body parts as do some of the other creation accounts.[xiii] Genesis is a straightforward narration of the creation events, without any need for columns of turtles, body parts of gods falling to earth, and other fanciful elements common to pagan creation myths.[i] “Creationism support is at a new low.

Tag: 上海后花园论坛 Sanlam in R1.9bn Indian investment
“In terms of the agreement with Shriram, Sanlam will subscribe for an effective 26% interest in Shriram Capital through a cash contribution of R1.9-billion, while Sanlam’s 26% interest in both Shriram Life Insurance and Shriram General Insurance will also be transferred to Shriram Capital,” Business Day quoted Sanlam Group CEO Johan van Zyl as saying. Shriram Capital’s activities include commercial financing, retail financing, distributing wealth products and stock broking. It also has a majority holding in each of the life and general insurance joint ventures with Sanlam. South African financial services group Sanlam is to acquire a 26% stake in its Indian partner Shriram Capital for R1.9-billion, as part of of its strategy to to diversify both geographically and into broader financial services. “We are pleased to build on our already strong relationship with Shriram, which has developed through our involvement with the two insurance entities over the past five years.” “This investment is in line with the company’s strategy to diversify both geographically and into broader financial services,” he said in a statement last month. 21 September 2011 This includes potential consolidation in some markets as well as expansion into new countries, with Mozambique likely to be added in 2011. The transaction, which is still subject to approval from the various regulatory authorities, is seen as a way for Sanlam to more efficiently utilise its discretionary capital of R3.2-billion.

Van Zyl explained that a Sanlam investment in Shriram Capital better aligned the group’s interest with that of their Indian partner, and provided Sanlam with access to the strong growth and profit generating capacity of the financing entities.
Share Facebook Twitter Google + LinkedIn Pinterest Every job has its ups and downs, but Brett Cuthbert admits that it is hard to get too frustrated when surrounded by thousands of beautiful flowers — especially around the holidays with acres of poinsettias under glass. “If you’re having a bad day you can walk into the greenhouse and see flowers,” Cuthbert said. “You have to love what you do and being able to see flowers every day certainly isn’t bad.”Brett is part of the third generation to run Cuthbert Greenhouse, Inc., in Franklin County that specializes in wholesale production of a wide variety of plants. The greenhouse business was started in 1951 to supply starter plants for the family’s 30-acre farm near Groveport. The operation has grown to two locations with 13 acres under glass and a small retail market. They primarily sell to Kroger, Giant Eagle, Kmart and other large retailers in the Columbus area.“We try to stay within 150-mile radius around Columbus most of the time,” he said. “We do go outside of that some, but that gets us in all of Ohio out to Indiana, Pittsburg and West Virginia. We do not typically go into Michigan much.”Of course, Easter and Mother’s Day are vitally important to the business but there is not much more stunning than when the greenhouses are filled wall-to-wall with the holiday hues of popular poinsettias this time of year. They sell between 150,000 and 170,000 poinsettias a year in 4.5-inch, 6.5-inch, 8-inch, and 10-inch pot sizes, with the 6.5-inch size being the most popular.One of the most significant challenges with poinsettia production is anticipating what the newest trends will be in the quickly changing retail market.“We have to order our cuttings in February and trying to guess what the retailers want and how many they want the following Christmas can be tough. Will they switch something? It is not like manufacturing where they can tell you three weeks ahead of time and things can be changed,” Cuthbert said. “We place our initial order based on the previous year and then talk to customers about any changes they are considering. You have to have open communication with your customers to make sure you are supplying what they need. Sometimes it is a pure guess. Then, we always try to produce around 10% more than what we know we are going to need. Some of that extra production is due to plant loss that we will have and some is due to people wanting to change things. You need to sell everything you have grown, so you do not want to produce too many. It is a real balancing act.”Painted and glitter covered poinsettias are a recent trend for buyers.In general, the trends are fairly stable for poinsettias, but the details can change quite a bit with new varieties and shifting customer demand.“We buy un-rooted cuttings for three or four different reds and then we have marbles, pinks, whites and others. We usually have around 20 different varieties tailored around what is the best for us and what our customers want,” Cuthbert said. “Red is always the bulk of our poinsettias — around 75% of what we sell. I personally like the ones that are a little different.”White and pink poinsettias are increasingly popular because they are the most common colors for painting, which is a current trend.“We are doing more painting with floral paint and glitter. That is becoming more popular. It started five or six years ago and it has been growing more and more,” he said. “When we are painting them, it is on a white poinsettia 90% of the time. You can’t do it with spray paint. You have to use floral paint that lets the plants breathe. Floral paint has an alcohol base so a lot of it evaporates off. After you paint it and let it dry, you spray it with watered down glue and sprinkle the plants with glitter. It is a long drawn out process.”The cuttings for the poinsettias begin arriving in June and are started based on the desired end size and sale date of the plants.“After we get the cuttings we stick them in oasis to root them out for two to three weeks. Then we transfer the plant to a pot with our standard soil mix and wait until that roots out to the edge of the pots. To determine the number of bracts, which are the sets of colored leaves, you have to take a pinch off its top and that makes it fuller. If you pinch it too low you won’t have enough leaves. We do that around six weeks after we start them,” he said. “You have to grow the products to the correct specs for the customer. You have to make sure it is the right size with the right number of bracts. If it doesn’t meet those specs we leave it behind and we only sell the ones that meet the criteria. For an 8-inch pot, for example, you want at least 15 bracts. If you have too few it can hurt you. More is OK. An 8-inch pot and 10-inch pot have three plants and the smaller pots have two. You have to grow what the customer wants.”Poinsettias are among the more costly plants produced in the greenhouse due to the supplemental heat they require.“The poinsettia demand for us really depends on how many people are growing poinsettias. You have to heat all of these greenhouses and that cost often determines if people will grow them or not. We use natural gas for heat,” he said. “Poinsettias and the spring crops cost more to produce because of the heating costs we have.”The plants have to be carefully managed to maintain consistent quality.“When you water poinsettias you can’t get water on the leaves, so we have them on drip irrigation or ebb and flow bench irrigation where the water comes up from the bottom,” he said. “When you see a poinsettia you want a nice pristine leaf. Water leaves spots.“Insects can be a problem with poinsettias too. You just have to be diligent with them. White fly is the main pest. You just have to stay on top of it with your spray program. You can get botrytis if they sit wet. We have a fungicide in our soil medium to prevent problems with that. We always need to use new pots and fresh soil because you do not want to bring something in. When it gets to the store we can’t control it, so we need to do what we can to prevent problems after the plants leave here.”After months in the greenhouse, the sales season starts in mid-November as the plants assume their final hues.Water can leave unsightly spots on poinsettias.“Different varieties color up differently. Later varieties take longer to turn colors. You can also trick them with black cloth to give them shorter days and longer nights. They are photosensitive and that will make them turn faster if you need them really early. For most of them we don’t do that,” he said. “When they’re ready, we pull poinsettias one day and ship them to the store the next day. You don’t want a live plant sitting in a box for more than a few days.”The vast majority of the plants go to large retailers, but some are sold to smaller retailers, organizations and churches as well.“Fundraisers are really good for fall and Christmas so we do them with mums and poinsettias. We sell them at wholesale cost and then they can add $2 to $5 to them and raise money. Prices for us depend on the order size,” Cuthbert said. “We ship poinsettias until Dec. 24 when we take some to churches who want them for Christmas.”If they have too large of a supply, they can usually find someone who needs poinsettias and, likewise, when the Cuthberts come up short, they can usually find what they need.“The greenhouse industry is about friendly competition. If we need something we can buy it from somewhere else and if others need something they buy it from us. We help each other out,” he said. “Last year we ran short on 8-inch and 10- inch plants and we had to go to Cleveland to find them, but we have also had extra production where we have shipped to Texas in the past.”Cuthbert, his brother and cousin run the business with the help of up to nearly 50 seasonal employees at different points during the year. There are certainly challenges in keeping their market-savvy and budget-conscious retail customers happy, but even on the toughest days the Cuthberts have acres of reasons to smile.
