NASA-Ames Research Center has produced an online simulation game called AstroVenture that allows kids to try to design a habitable planet. After they pick half a dozen parameters, the game tells them whether humans could live there or not.This is a cute feature that, with caveats, could be useful for parents and teachers. The main problem is that it is too simplistic. The planet-construction dialog asks what kind of star you want to put your planet around, how close to the star, how big it is, whether it has water and a few other things. These are fine and good, but not enough. It doesn’t discuss many other factors that could be show-stoppers: crustal composition, type of atmosphere, place in the galaxy, eccentricity of the orbit, size and distance of moon, and much more. Still, kids may be surprised to find how few of their choices actually work. Of course, the Astrobiology folks behind AstroVenture want kids to learn early how to speculate about life in outer space. They want to help kids exercise the power of imagination and speculation, since these are prerequisites for Darwin Party membership later. All that aside, learning that only a small subset of possible planets are even in the ballpark for life is a worthwhile lesson. For junior high and older, use this in conjunction with the film The Privileged Planet.(Visited 8 times, 1 visits today)FacebookTwitterPinterestSave分享0
– This October 30th, join fellow South Africans as we celebrate the spirit of Ubuntu and launch #GivingTuesdaySA in partnership with Brand South Africa.#GivingTuesdaySA is a global day of giving that harnesses the collective power of individuals, communities and organisations to encourage philanthropy and to celebrate generosity worldwide. Following the widely recognised shopping events Black Friday and Cyber Monday, this year’s #GivingTuesdaySA will take place on November 27th and will kick off the giving season by inspiring people to collaborate and give back.Laura Parker, Executive Director for Boys & Girls Clubs of South Africa, and the Global Lead for #GivingTuesdaySA, shared: “I volunteered to get involved in the movement as it’s a pervasive idea that brings the social sector together towards a common goal. Not only does it speak to what non-profits really need, which is funding to support their critical, ongoing operations, but it also celebrates and recognises organisations and individuals who already give.”Founded in 2012 by the 92nd Street Y – a community and cultural center in New York City − #GivingTuesday has inspired millions of people to give back and support the causes they believe in. Over $300 million was raised online to benefit a tremendously broad range of organisations, and much more was given in volunteer hours, donations of food and clothing, and acts of kindness in 2017.“We are incredibly inspired by the way the #GivingTuesday community has embraced this concept for a worldwide movement,” said Henry Timms, founder of #GivingTuesday and Executive Director of 92Y. “As we prepare for November 27, we’re energised and encouraged by the community’s generosity. The levels of creativity, effort and the quality of the new ideas people have contributed and shared are phenomenal.”Terry Pheto, Kabelo Mabelane & Danny Koppel, Brent Lindeque, and Bokang M Tshabalala have all offered their giving stories, in support of #GivingTuesdaySA. They share how they support initiatives and give hope through Save the Children South Africa, the Shout Foundation, the Good Things Guy, and the Bokang Montjane Foundation respectively.Added by Toni Gumede, Strategic Relationship Manager from Brand South Africa: “We are excited to launch this movement in South Africa as it speaks to active citizenship, mobilising individuals around social causes, and has a collaborative value system built into it, which is directly tied to our values as an organisation, and to who we are as South Africans.”The Nelson Mandela Foundation also expressed its support of #GivingTuesdaySA as the ethos of the movement ties firmly in with the centenary celebrations.For more details about the #GivingTuesdaySA movement and/or to set up interviews, please contact:Ntombi NtanziTel: +27 11 712 5071Email: [email protected] www.givingtuesdaysa.org or www.brandsouthafrica.comSocial Media: @GivingTuesdaySA @BrandSouthAfrica @PlayYourPart
Your dream client has seen your kind before. They’ve seen the new salesperson come in full of excitement and ambition. They’ve seen that salesperson work like the devil to build consensus around a deal. They talked a great game, and they did a wonderful job selling themselves and their company.Then it came time for the execution. The salesperson was nowhere to be found, and all of the calls for help went to people they’d never even met. Sometimes the execution on the original sale went okay, and the salesperson was present. But then he had the business, and there wasn’t any reason to show his face or spend time with them anymore. Complacency set in, and it was followed closely by dissatisfaction. A dissatisfaction that went unnoticed until it was too late.Now you’re here, all full of piss and vinegar. You look familiar. You sound familiar. It conjures up memories of promises made and not kept. The promises are new coming from you, no doubt, but they sound the same. You can see that your dream client contacts are incredulous. It’s written all over their faces.And so your dream client contacts begin to ask themselves this question: “How long before you too disappear?”Where will you be when the bullets start flying?What is your plan to go from quarter to quarter, from project to project, continually finding ways to help your dream client?What is your plan to keep from growing complacent and to help keep your client from growing complacent?How do you and your dream client contacts continue to work together to go from success to success, always pushing the boundaries out a little further and helping each other grow?Why should your dream clients believe that you are any different than those that have come before you, those that made the sales they needed to make and slowly faded away, never to be heard from again?Sales is a fashion business. Every season you have to release a new line. You have to find something new and interesting to show your clients. And it must be something that makes a difference for them and their business. If you are going to be relevant, you can’t disappear. If you are going to earn your place as their strategic partner, you have to maintain a presence.Don’t disappear.

When announcing the signings of nine recruits who will be coming to Ohio State as members of the men’s track and field team next season, OSU interim coach Ed Beathea said he believes the future of the team he is coaching is bright. “This is the best recruiting class we have put together in my time at Ohio State,” Beathea said in a press release. OSU will welcome a broad range of recruits in its incoming class. The class includes five athletes from Ohio, but also adds four out-of-state recruits. Among the class are three distance runners, two sprinters, one hurdler, two throwers and one multi-event athlete. Donovan Robertson, a hurdler from Berea, Ohio, headlines the class. Robertson, the 2011 Ohio Gatorade Track and Field Athlete of the Year, has many accomplishments to his name. This year, Robertson set the indoor national record in the 60-meter hurdles, completing the event in 7.57 seconds. Robertson is also the defending state outdoor champion in the 110-meter hurdles and 300-meter hurdles, and was named to the 2011 USA Today All-USA track and field team. Beathea said he recognized the significance of signing Robertson. “Donovan is one of the most talented signees in OSU history,” Beathea said in the press release. “He will have an instant impact on our conference and the country.” The group of in-state recruits is also highlighted by distance runners. Steven Weaver, from Napoleon, was the 2011 Division II state champion in the outdoor mile run and in cross country. The team also added Nicolas Pupino of Copley and Jordan Redd of Fairborn. Jack Kincade from Hilliard is the fifth in-state recruit in the class. Kincade scored 6,243 points in the decathlon last season, which was the sixth-best decathlon score among all high school athletes nationwide in 2011. OSU also lured four recruits from farther east to come west. Champ Page, a sprinter from Marlboro, Md., is a six-time Maryland state champion. Page finished the 2012 indoor season with times that ranked second nationally in the 300-meter dash with 33.93 seconds, third in the 500 meter with 63.71 seconds, and 11th in the 400 meter with 48.28 seconds. Justin Burke, a sprinter from Virginia Beach, Va., is a two-time defending outdoor state champion in the 100-meter dash, as well as in the 200 meter and 400 meter. Two throwers will also come to the Buckeyes from other states. Joseph Velez, from Providence, R.I., is joined by javelin thrower Billy Stanley from South Park, Pa. Assistant coach Kevin Mannon praised both incoming throwers. “(Velez) has the ability to make an immediate impact on the Big Ten and NCAA championships in 2013,” Mannon said in a press release. “Billy has already thrown a mark that can score at the Big Ten championships, so we expect him to be a major player for us in 2013.”
