The Miura fold
, a type of rigid origami
that works by folding flat, rigid sheets with hinges, has a number of uses. For instance, It's great for folding a map, because Interdependence of folds means that it is very difficult to reverse them and the amount of stress place on the map
, and can be used on solar panels that need to be folded and unfolded by automation
, as deployment only requires one motor, and to transport materials for telescope lenses that originally would be too big to fly into space
. Here's one schematic for duplicating the Miura fold
(PNG), and a simplified version
(YouTube). More information and fun with scientific origami

Judgmental maps of cities/areas
including Los Angeles (featuring “botoxed cougars in luxury condos”), Northern Virginia (including “closeted Hispanic husbands”), Richmond, VA (where one finds the “scary Walmart”), Memphis (where there are “people proud, yet ashamed, to be from Memphis"), Chattanooga (see “rich white people & gnomes”), Nashville (one part is “gentrified to a great level of inconvenience”), Phoenix, San Antonio, and “Canada, prolly.”

Tencent Maps - Look at some of the remotest parts of China. While some of the off-the-beaten-path images on Tencent Maps are actually static panoramas, other more quirky routes offer full coverage for mile after mile, as seen on the Li river in Guangxi province where you can cruise on a boat amidst the famous karst peaks that don’t look like any other hill or mountain range you’ve ever seen before.

A single mom, Nicole just completed a degree in early childhood development at the local community college. She has been patching together part-time work around her studies and Joe’s schedule. Until 2009, Nicole and Joe lived in a poor neighborhood in Baltimore. Now they’re in Columbia, Md., half an hour away by car, but a world away in terms of opportunity.
At Joe’s former elementary school in Baltimore, 97 percent of the students are low income, and 97 percent are African-American. His middle school in Columbia is one-third low income, with white, Asian, Hispanic and multiracial students making up just over half the population.
In their old Baltimore neighborhood, Nicole says, she saw a man get shot in the leg in front of a corner bar as she held baby Joe in her arms.

Over the course of nearly 20 centuries, millions of East Africans crossed the Indian Ocean and its several seas and adjoining bodies of water in their journey to distant lands, from Arabia and Iraq to India and Sri Lanka.
Called Kaffir, Siddi, Habshi, or Zanji, these men, women and children from Sudan in the north to Mozambique in the south Africanized the Indian Ocean world and helped shape the societies they entered and made their own.
Free or enslaved, soldiers, servants, sailors, merchants, mystics, musicians, commanders, nurses, or founders of dynasties, they contributed their cultures, talents, skills and labor to their new world, as millions of their descendants continue to do. Yet, their heroic odyssey remains little known.
The African Diaspora in the Indian Ocean World traces a truly unique and fascinating story of struggles and achievements across a variety of societies, cultures, religions, languages and times.
