In 2013, the world learned that the NSA and its UK equivalent, GCHQ, routinely spied on the German government. Amid the outrage, artists Mathias Jud and Christoph Wachter thought: Well, if they're listening ... let's talk to them. With antennas mounted on the roof of the Swiss Embassy in Berlin's government district, they set up an open network that let the world send messages to US and UK spies listening nearby. It's one of three bold, often funny, and frankly subversive works detailed in this talk, which highlights the world's growing discontent with surveillance and closed networks.

From rockets to stock markets, many of humanity's most thrilling creations are powered by math. So why do kids lose interest in it? Conrad Wolfram says the part of math we teach -- calculation by hand -- isn't just tedious, it's mostly irrelevant to real mathematics and the real world. He presents his radical idea: teaching kids math through computer programming.

Basketball is a fast-moving game of improvisation, contact and, ahem, spatio-temporal pattern recognition. Rajiv Maheswaran and his colleagues are analyzing the movements behind the key plays of the game, to help coaches and players combine intuition with new data. Bonus: What they're learning could help us understand how humans move everywhere.

As quantum computing matures, it's going to bring unimaginable increases in computational power along with it -- and the systems we use to protect our data (and our democratic processes) will become even more vulnerable. But there's still time to plan against the impending data apocalypse, says encryption expert Vikram Sharma. Learn more about how he's fighting quantum with quantum: designing security devices and programs that use the power of quantum physics to defend against the most sophisticated attacks.
