Join a physicist, a neuroscientist, and a linguist as they explore the deep enigmas of time. Time feels like it flows, but does it? Time seems to have a built-in direction, from past to future, but is that real or merely a quality imposed by the human brain? Time on earth elapses at a uniform rate, so why does the human experience of time seem so varied? How do various neurological afflictions change the perception of time? And underneath it all, how does human language impact our ability to think about time and fully experience its rich and mysterious contours?

PARTICIPANTS: Lera Boroditsky, Dean Buonomano

Mathematical mysteries have challenged humanity’s most powerful thinkers and inspired passionate, lifelong obsessions in search of answers. From the strangeness of prime numbers and the nature of infinity, to the turbulent flow of fluids and the geometry of hyperspace, mathematics is our most potent tool for revealing immutable truths. The event was a vibrant tour to the boundaries of the mathematical universe, and explore the deep puzzles that have been solved, the masterminds who powered the breakthroughs, and the towering challenges that have shaken the confidence of some of today’s most accomplished mathematicians—even as they enlist new ways to pursue mathematical truths.

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.

Probability is the backbone of science, but how well do you understand it? Odds are, not as well as you think; it is a surprisingly subtle concept that is often misunderstood, sometimes even by professionals who use it to guide crucial and far-reaching decisions. In this program, experts from technology, physics, medicine, and programming explore the slippery side of probability and the powerful role it plays in modern life.

Can the spooky world of quantum physics explain bird navigation, photosynthesis and even our delicate sense of smell? Clues are mounting that the rules governing the subatomic realm may play an unexpectedly pivotal role in the visible world. Join leading thinkers in the emerging field of quantum biology as they explore the hidden hand of quantum physics in everyday life and discuss how these insights may one day revolutionize thinking on everything from the energy crisis to quantum computers.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

Brass casting, making pottery and firing it, wood carving, spinning, weaving, stamping adinkra cloth, dyeing with indigo, smelting and forging iron, and more. From Burkina Faso, Cape Verde, Ghana, Nigeria.

THIS IS A DEMONSTRATION. THIS IS HOW THEY DID IT TWO CENTURIES AGO. NOW THEY BUY THEIR IRON IMPORTED FROM CHINA, JUST AS WE DO. Smelting iron from ore by a smith family in West Africa. The only complete, high quality video of iron smelting in Africa. Making charcoal, digging ore and flux, building the kiln, firing the kiln, sacrifices, smelting the iron, forging the iron into tools. With Chinese subtitles. A CULTURAL RECREATION !! THIS WAS DONE FOR ME TO FILM. THEY DO NOT SMELT IRON LIKE THIS ANYMORE.

This video is about African pottery forming and firing.

Videos and photos of pottery techniques in several communities in southwest Nigeria.

This video demonstrates the five major techniques used by potters in Burkina Faso, Ghana, and Nigeria. The techniques include concave mold, convex mold, coiling, direct pull, and hammer and anvil. You can see Bwa, Jelly, and Mossi potters in Burkina Faso, the Ashanti potters in Kumasi Ghana, and Igbo and Yoruba potters in Nigeria. In addition there are two detailed videos of pottery firing.
