"Mistaking planning for strategy is a common trap. "
A small army of landmine-detecting rats is to be redeployed in Mozambique in a push to meet a deadline to have the country declared free of mines this year.
Belgian non-governmental organisation Apopo trains African giant pouched rats to sniff out the explosives in landmines by conditioning them to associate the scent with rewards of food.
The rats undergo nine months of training, learning to sniff out the explosives in old landmines buried underground. They scratch the ground to alert their handlers to mines.
The rodents are quick learners and easy to work with, according to Alson Majanzota, leader of one of Apopo’s rat handling teams. The animals can check 200sq m of land for mines in 30 minutes; a human armed with a metal detector could take up to three days to do the same job, he adds.
"You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete. "
A Guide to Different Kinds of Parallel Universes
These days it often seems that if a theory has loose ends, its dangling threads are surreptitiously tied together out of view within the hidden fabric of a parallel universe. While some researchers recoil from introducing unseen aspects to a theory, others find that the invisible knots create an irresistibly pretty package.
Depending on one’s taste, there are so many types of parallel universes to choose from—alternative cosmos galore. If extra dimensions are not your thing, maybe bifurcating timelines would work. If an endless array of gigantic bubble universes seems intimidating, then perhaps a nursery of baby universes is more endearing. While there is not yet a GPS device or app to navigate through the cartography of scientifically sanctioned parallel possibilities, perhaps this guide to all things alternative will help.
Vacant city lots and buildings are often used as starting points for cultural innovations. Over the course of the transformation of the postindustrial city, public space has become an exciting laboratory for interdisciplinary cooperation between artists, architects, urban planners, and landscape architects.
