Embracing technology in less developed nations
Scott McLeod, J.D., Ph.D., is an Associate Professor of Educational Leadership at the University of Kentucky. He also is the Founding Director of the UCEA Center for the Advanced Study of Technology Leadership in Education (CASTLE), the nation’s only academic center dedicated to the technology needs of school administrators, and was a co-creator of the wildly popular video series, Did You Know? (Shift Happens). He has received numerous national awards for his technology leadership work, including recognitions from the cable industry, Phi Delta Kappa, and the National School Boards Association. In Spring 2011 he was a Visiting Canterbury Fellow at the University of Canterbury in New Zealand. Dr. McLeod blogs regularly about technology leadership issues at Dangerously Irrelevant and Mind Dump, and occasionally at The Huffington Post. He can be reached at scottmcleod.net.
The mission of the One Laptop per Child initiative begins:
"Most of the nearly twobillion children in the developing world are inadequately educated, or receive no education at all. One in three does not complete the fifth grade.\n\n
The individual and societal consequences of this chronic global crisis are profound. Children are consigned to poverty and isolationjust like their parentsnever knowing what the light of learning could mean in their lives. At the same time, their governments struggle to compete in a rapidly evolving, global information economy, hobbled by a vast and increasingly urban underclass that cannot support itself, much less contribute to the commonweal, because it lacks the tools to do so."\n\n
I have been talking with collegues lately about the future of education and technologies that will fuel change. The question is usually how will advances in technology such the Nokia N800, a Wi-Fi Internet tablet which includes VoIP support and WiMax which enables long range wireless broadband access change society in less developed nations? Will these tools along with initiatives like the One Laptop per Child change education in less developed nations?\n\n
I read a lot of work by naysayers who claim that less developed nations simply do not have the capacity to embrace such technologies. I agree if we restrict our discussion to a physically tangible ICT environment...but wireless technologies change the game. For starters, simply look at how many developing nations now have more cell phones than landline telephones. When I was recently in Cambodia I had cell phone access everywhere! Even in rural areas 6 hours away from any major town I always had good reception and never had a dropped call. There is promise if planners and policymakers think outside of the box.\n
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Protected animals are feared to be headed for the black market.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
