What rocks can teach

first_imgTo Francis Macdonald, Harvard’s vast collection of gems, minerals, and rocks constitutes more than just a pretty face.The collections, showcased in a gallery at the Harvard Museum of Natural History, have long included the showstoppers: fantastic crystalline shapes of brilliant red, orange, and blue; semiprecious gems; and even meteorites, visitors to Earth from the distant asteroid belt.But Macdonald, an assistant professor of earth and planetary sciences, thought the venerable gallery should go beyond just “pretty,” incorporate more science, and tell more about the story of the Earth and the processes that created it.That sensibility is what drove a renovation of the Earth and Planetary Sciences gallery at the Harvard Museum of Natural History, one of the Harvard Museums of Science and Culture. Macdonald and museum officials felt it was time to link the beauty that has always been there more closely to the story of the Earth and to the work of faculty members in the Department of Earth and Planetary Sciences.Francis Macdonald, an assistant professor of earth and planetary sciences, thought the venerable Earth and Planetary Sciences gallery should go beyond just “pretty,” incorporate more science, and tell more about the story of the Earth and the processes that created it.“The data for these stories [about the Earth], we actually get from these stones,” said Macdonald, the lead scientist who helped to develop the new exhibits. The renovation was funded partly by the department and partly through a grant Macdonald received from the National Science Foundation.The renovated gallery, which opened early this month, includes new panels telling the history of the Earth, starting with plate tectonics and continuing along a timeline running down the east wall. The timeline features specimens for visitors to touch, including a sample of the oldest rock on Earth, a stone from a time when the planet was nearly entirely covered in ice, and samples illustrating the rise of life on Earth (though in keeping with the gallery’s geological theme, it is life turned to stone in the form of fossils).The renovation also saw the removal of several display cases in the center of the room to make space for an exhibit that will showcase the work of faculty members. Now, it represents Macdonald’s work in the Arctic, and includes a large relief map of the region with the ice removed, touchable so visiting schoolchildren can get a feel for the undersea ridges and ocean basins.The specimens on display are just part of a vast collection held by the Harvard Mineralogical and Geological Museum, which is one of three museums that make up the Museum of Natural History. The collection, used for both teaching and research, holds 300,000 specimens, including samples of nearly 600 meteorites and 1,000 gemstones.Associate curator Raquel Alonso-Perez said that the renovations included refurbishing the existing display cases and improving lighting. Officials reviewed the samples on display, replacing about half of the 3,000 specimens there, Alonso-Perez said, and dedicated one case to birthstones, which visitors often ask about.When asked about his favorite specimens, Macdonald turned from the more showy samples to those he has collected personally, which not only conjure memories of his field trips, but also help him to tell the scientific story of how today’s Earth came to be.“The idea is that the rocks are the data,” Macdonald said. “One of the [motivations] for me is showing that geology and mineralogy are active and alive.”The specimens on display are just part of a vast collection held by the Harvard Mineralogical and Geological Museum, which is one of three museums that make up the Museum of Natural History.

AFC will rise from derby blues, says Mbungo

first_img0Shares0000AFC Leopards head coach Cassa Mnungo watches on during the Mashemeji Derby against rivals Gor Mahia at the Kasarani Stadium on February 9, 2019NAIROBI, Kenya, Feb 10 – AFC Leopards tactician Cassa Mbungo is upbeat the club will recover from the current slump, their derby day 2-0 loss to arch rivals Gor Mahia at the Kasarani Stadium on Saturday afternoon seeing them slump only one point away from the relegation zone.AFC have lost five of their last six games and the Rwandese tactician only brought on board last week after the departure of Serb Marko Vasiljevic is confident he can turn around fortunes at the den. “We will do well, I have faith. We will work on our weak areas and especially now that we are almost going for the international break, I will have more time to work with the team and rectify the mistakes we made,” Mbungo said after his side’s loss to Gor on Saturday.He added; “Tactically we did some things right and we were okay, but we still have work to do. We conceded goals from set pieces and our defending was a bit naïve from them. But we will work in training and I will show them what to do in certain instances.”AFC have a tough run of fixtures awaiting them as Mbungo tries to lift the limping giants off the doldrums of relegation.They play Ulinzi Stars next weekend before facing Mathare United and Sony Sugar prior to the international break.AFC Leopards players hurdle together before the Mashemeji Derby against rivals Gor Mahia at the Kasarani Stadium on February 9, 2019With the transfer window also set to open, Mbungo has hinted that he might work on a few transfers though he says he believes in the squad currently at his disposal.“We need to strengthen the team and if I have an opportunity to do so then I will bring in some players. But first, we have to work with those we have because I think they are good enough and if we can work to improve them, we will have a good team,” he stated.He picked out the defense as a key area he needs to work on saying he is appalled by the number of goals his side is conceding.“In four games we have conceded nine goals and that is an area that we have to really work on. Also, we are not creating chances to score on the other end and this is also a concern. There’s a lot we need to work on,” the tactician stated.0Shares0000(Visited 1 times, 1 visits today)last_img read more

Arts festival celebrates turning 40

first_img24 April 2014South Africa’s National Arts Festival, held in Grahamstown in the Eastern Cape, is celebrating its 40th anniversary this year.The main programme will feature artists from 26 countries in more than 550 performances in theatre, dance, performance art and music, the festival said in a press release on Wednesday. It will include the work of 65 former Standard Bank Young Artist Award winners.The festival has commissioned nine music works, with musicians with more than 40 South African Music Awards and three Grammy Awards between them on the bill.They are also planning “an ambitious, sprawling ‘Creation of a Nation’ project across Grahamstown”.“It is a bold programme that veers between the extravagant and the intimate as it attempts to reflect on major milestones – of the festival, of the Young Artist Awards – which have been sponsored by Standard Bank for 30 years – and of South Africa, in our 20th year of democracy,” artistic director Ismail Mahomed said.The event, which contributes an estimated R349.9-million to the economy of the Eastern Cape each year, has become a touchstone for the state of South African art. “This year our artists have risen to the triple-anniversary challenge with some extraordinary proposals that we are excited to bring to life,” Mahomed said.Balancing the Main programme is the vast and exciting fringe, supported primarily by the National Lottery Distribution Trust Fund. “The fringe, also celebrating an anniversary as it is presented for the 35th time, continues to grow as South Africa’s biggest open-access platform. Hundreds of productions bring their talent to Grahamstown and fill theatres with their work across every conceivable genre,” Mahomed said.Straddling the Fringe and the Main is the increasingly popular Arena programme, which showcases the work of previous Standard Bank Ovation Award winners as well as award-winning work from other Festivals around the world – this year including the Amsterdam, Prague and the Adelaide Fringe Festivals.ThinkfestThe Thinkfest programme will feature a recording of two panel discussions by the BBC World Service for broadcast globally to the service’s estimated 180-million listeners.Winners of the Short Sharp Stories Award for fiction writing and the Arts Journalist of the Year award will be announced at the festival.‘Family fare’The Children’s Arts Festival and the Fingo Festival in Joza are just two of the initiatives which aim to reach out to families and younger audiences in the festival’s drive to create new and sustainable auidences.“We’re also featuring, on our Arena programme, one of the world’s best beatboxers – Tom Thum – in collaboration with musician Jamie MacDowell, which will appeal to the whole family,” Mahomed said.“We’re giving audiences the opportunity to think, reflect, celebrate, empathise, laugh and to look to the future through this year’s programme,” Mahomed said. “We’re proving that life begins at 40!”Bookings for the 2014 National Arts Festival open on 9 May and can be made online at www.nationalartsfestival.co.za.Programmes can be obtained through selected Exclusive Books and Standard Bank branches from the beginning of May.The National Arts Festival is sponsored by Standard Bank, The National Lottery Distribution Trust Fund, The Department of Arts and Culture, The Eastern Cape Government, City Press and M Net.Source: National Arts Festivallast_img read more

iPhone App Lets Soldiers Map Their Battlefields

Grange: I Will Always Love Seaga

first_imgThe Minister of Culture, Gender, Entertainment and Sport, the Honourable Olivia Grange, has paid tribute to the former Prime Minister, the Most Honourable Edward Seaga, who passed away today.Minister’s statement follows:“Some people make such a telling impact on people, communities and countries — and Edward Seaga was one of them.He was the kindest, most caring, most brilliant man I’ve ever known and I loved him dearly. It has been my greatest pleasure to learn from him and to work with him.He taught me to dine with kings and walk with beggars and to give respect to receive respect.Today on his 89th birthday, Jamaica and the world lost a great leader; and I have lost my teacher, my mentor and my friend.I give credit to Mr Seaga for much that I have achieved in my professional life.He saw great potential in me and invested his time and effort into helping me to rise and to contribute to the country that we both love.Mr Seaga loved Jamaica and our people. He understood the value of our culture and way of life in a way that few other people do. He dedicated his life to advancing Jamaica in every way; and we have become a cultural powerhouse because of Mr Seaga’s vision and service.All of us — especially those of us from West Kingston — are heartbroken today — he was ‘closer than a brother.’ But in this moment, we are also proud to have benefitted from, be associated with, and counted as family by Edward Seaga.And to us, he was and will always be family.Thank you for your service, Mr Eddie. Thank you for loving us and working so hard for each of us every day. Walk good. I will always love you.”last_img read more
