On the Sea Islands along the coasts of South Carolina and Georgia, a painful chapter of American history is playing out again. These islands are home to the Gullah or Geechee people, the descendants of enslaved Africans who were brought to work at the plantations that once ran down the southern Atlantic coast. After the Civil War, many former slaves on the Sea Islands bought portions of the land where their descendants have lived and farmed for generations. That property, much of it undeveloped waterfront land, is now some of the most expensive real estate in the country.
But the Gullah are now discovering that land ownership on the Sea Islands isn’t quite what it seemed. Local landowners are struggling to hold on to their ancestral land as resort developers with deep pockets exploit obscure legal loopholes to force the property into court-mandated auctions. These tactics have successfully fueled a tourism boom that now attracts more than 2 million visitors a year. Gullah communities have all but disappeared, replaced by upscale resorts and opulent gated developments that new locals — golfers, tourists, and mostly white retirees — fondly call “plantations.”
Faced with an epic case of déjà vu, the Gullah are scrambling for solutions as their livelihood and culture vanish, one waterfront mansion at a time.

Every Google search, OKCupid date, and Netflix recommendation, and even the items and prices you see at the grocery store is uses massive amounts of data. Algorithms of increasing complexity make sense of this ever-expanding mountain of data, and are helping us achieve unprecedented insights into medicine and other fields, create even more powerful computers, and much more. Watch scientists James Fowler, Steven Strogatz, Andrew Lo, and Seth Lloyd crunch the numbers in "Go Figure: Predicting the World With Math," part of the Big Ideas series from the 2014 World Science Festival.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

From a bee’s hexagonal honeycomb to the elliptical paths of planets, symmetry has long been recognized as a vital quality of nature. Einstein saw symmetry hidden in the fabric of space and time. The brilliant Emmy Noether proved that symmetry is the mathematical flower of deeply rooted physical law. And today’s theorists are pursuing an even more exotic symmetry that, mathematically speaking, could be nature’s final fundamental symmetry: supersymmetry. Join some of the world’s preeminent scientists to explore the core role symmetry plays in our unraveling of nature’s deepest secrets—and catch a glimpse of profoundly important symmetries that may be awaiting us just over the horizon.

This is one of several films made at Imperial College London in conjunction with ICI. The entire film, except for a short end sequence, was shot in the laboratory of Professor Eric Laithwaite at Imperial College London. This is one of many examples demonstrating electromagnetic forces and in particular the linear induction motor for which Eric Laithwaite was famous. Many of what he called his 'toys' are seen, these are models that help demonstrate the concepts and forces of electromagnetic induction etc.
This was currently the best transfer from 16mm film that we had of this unique engineer in his 'work place', but for a better quality version please now go here: https://youtu.be/CmKF72CPR0s
