My favorite fun facts about the Sun, from the top of my head: *If you had a shield or something to hide from the light, you could actually go inside the atmosphere of the Sun without being fried. The density of the atoms up there is ridiculously low. But if you are not lucky and you catch one of those wanderer super hot atoms you’ll be instantly disintegrated :) ...
This is another quick idea I came up some days ago. I´d love to program this, but got no time... can you help me? A parser to plot the profession breakdown on biographies of people in Wikipedia, along History. The point would be to see a graph that, over time, shows which professions were more dominant for people that went into History (or, quite different in the Internet era, those that are Wikipedia worthy). ...
Exactly three years ago I defended my PhD in Goettingen, Germany. Today is my birthday as Doctor. Around then I had then an offer to work at best place in the world in my field, which I accepted. I also had an invitation to interview with McKinsey and was drafted for the astronaut election process. It was a great moment. Today I am unemployed. So What? I am where I am because I chose so. Pursuing your goals is not easy, but no one told me it would be. Achieving what I have, from where I started was not easy. By all means. What I am doing now is a hard step I knew I had to do. A difficult decision two years in the making. I studied science because I love science. And Technology. But most of all, how these help people be better. I studied science all the way up to earn a PhD and then also worked at a satellite and rocket facility. But something was missing. Something so important it drove me off the official path: People. As amazing, challenging and interesting as my research was, it lacked connection with the real world, with people. ...
Last Friday the US State Department hosted its 5th Tech@State, where technologist and diplomats unite to pursue goals in education, health, and welfare worldwide. The topic for this year was Open Source Software. All sessions are available in Ustream. I would especially recommend the one by Maccon Phillips, Dr. Linton Wells and Jeremy Allison. The feeling is that the model has changed. It is not anymore about hiring a company to provide a closed product and give support until they stop providing service or a new one is needed. The model now is to open the data, let everyone access as much information as possible. Anyone can then build (open) products that the agencies can evaluate and use. Every agency has now the power to create such open competitions. Agencies are keen to use open source software, as they realize it has many more benefits and fewer problems. They typically hire a company to adapt the product and provide service. The extra mile comes when they liberate the improvements for everyone to use, when they adopt the winning apps on competitions, when everyone can be engaged in the innovation, and everyone benefits from it. ...
This [free as pdf] NAP book is a report from the 2008 NRC Board of Atmospheric Sciences workshop: “Progress and Priorities of U.S. Weather Research and Research-to-Operations Activities”. Despite the chaotic nature of Weather, scientist are currently able to measure (nowcast) and predict (forecast) weather with unprecedented accuracy. Almost certainty within hours, and maybe a week at best with 50% chance. But: Do we need to improve our capabilities? Can we? The report says yes. What can we do? Once we have the forecast of an impending weather event, are we acting accordingly upon predictions? The report says not really. The U.S.A. has the world´s most sophisticated and well-developed weather forecast infrastructure. The federal government also spends, annually, $5 billion in research and operations only in NOAA, and $6 billion for a dedicated agency on disasters (FEMA). Academia and private partners are also tightly involved. Only the generation of weather forecasts costs overall $5 billion annually, but its benefits are (quoted on the book as) 6 times the cost. Despite these impressive benefits on paper, there is much room for improvement. ...
The video above shows the map of the Sun from 2007 to 2010. The map calculates the image as if neither the Sun or the Earth rotated, leaving thus a black region that corresponds to the section of the Sun that can´t be seen from Earth. But they do rotate, so the black region shifts in time. The interesting bit is that the solar features remain in place. This allows us to see that certain features survive several months and are indeed recurrent. ...
[vimeo https://vimeo.com/9182869 w=600] What you see here is the world response to the earthquake humanitarian crisis in Haiti. What you see here, each flash, is someone, somewhere in the world, going into OpenStreetMap.org, looking at aerial/satellites images, identifying features and adding them to the free map. If you want to learn, here I screencasted one of my edits back then as part of the Crisis Camp. After just 12 hours, and over the following days a large number of additions to the map are made with many roads (green primary, red secondary) added. Also many other features were added such as the blue glowing refugee camps that emerge. ...
My good Estonian friend Birgit Oidram had to do a small study, for the University of Malta, about the different perception of creativity as seen by an educator and a scientist. Interesting topic. I felt very honored when she called me and asked me to be ’the scientist’ in her study. We had our interview via Skype back in May. Today she sent me the end result. This is how she closes the study. I cannot agree more: ...
In 2005, in the context of rapid global changes at the time, Congress asked the National Academies to answer this: What are the top 10 actions, in priority order, that federal policymakers could take to enhance the science and technology enterprise so that the United States can successfully compete, prosper, and be secure in the global community of the 21st century? What implementation strategy, with several concrete steps, could be used to implement each of those actions? The Academies make independent, objective, and nonpartisan advice with high standards of scientific and technical quality. It stands on the credibility of more than 900 reports, many times biting the hand that feeds them. Sure enough they came up with these top action and recommendations , together with an excellent +500 pages report with a very strong rationale and the tough challenges ahead if not followed: “Without a renewed effort to bolster the foundations of our competitiveness, we can expect to lose our privileged position.” [Last phrase of the Executive summary] This was in 2005. So, what happened? This post is about what the NAS did 5 years later in lieu of the recommendations it produced, and what was done with them. ...
-Background and authorship info- Part of the Mirzayan fellowship was to propose topics on which to write a policy paper. This is the topic I submitted and 10 other fellows joined. This is the result of 2 weeks of work. Some of the authors requested their authorship to remain internal to NAS. Therefore, I am not including names besides mine. Also you will note many similarities with my individual brief, in which I concentrated into the subtopic of Crowdsourcing development. ...
