Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

Wanda Diaz Merced studies the light emitted by gamma-ray bursts, the most energetic events in the universe. When she lost her sight and was left without a way to do her science, she had a revelatory insight: the light curves she could no longer see could be translated into sound. Through sonification, she regained mastery over her work, and now she’s advocating for a more inclusive scientific community. "Science is for everyone," she says. "It has to be available to everyone, because we are all natural explorers."
We’re building an artificial intelligence-powered dystopia, one click at a time, says techno-sociologist Zeynep Tufekci. In an eye-opening talk, she details how the same algorithms companies like Facebook, Google and Amazon use to get you to click on ads are also used to organize your access to political and social information. And the machines aren’t even the real threat. What we need to understand is how the powerful might use AI to control us — and what we can do in response.
Right now, billions of neurons in your brain are working together to generate a conscious experience — and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we’re all hallucinating all the time; when we agree about our hallucinations, we call it "reality." Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.
Aleks Krotoski asks if we are haunted by our technology, or are we haunting it?
So much of our experience of technology can feel a bit like being haunted. It starts like any good ghost story with the just mildly unsettling; things aren’t were you left them or seem to have moved on their own within our devices. Its a creepy feeling that leaves you unsure about what to believe. Our understanding of how much of technology works is so limited that when it starts to behave out of the ordinary we have no explanation. This is when we start to make very peculiar judgement’s; "why did you do that" we plead, as if some hidden force was at work.
For some these feelings of being haunted by our technology can develop into full blown apparitions; keen gamers frequently experience Game transfer Phenomena where they literally see images of their game play in the real world, an involuntary augmented reality. While the hallucinations aren’t necessarily distressing in themselves the experiences can leave individuals questioning their sanity.
The coming internet of things will bring problems of its own; smart locks that mysteriously open by themselves for example as if under the influence of some poltergeist. Aleks herself has had the experience of digital ‘gas lighting’ (a term drawn from an Ingrid Bergman movie of a woman being driven mad by husband) when her partner logged on to their home automation system remotely and started to mess with the lights while Aleks was home alone. As one commentator puts it in a reworking of the old Arthur C. Clarke quote "any sufficiently advanced hacking is indistinguishable from haunting."
And as our devices and appliances increasingly start talking to each other bypassing us altogether who’s to say we, like Nicole Kidman’s character in The Others, haven’t become the ghost in the machine.
Machine intelligence is here, and we’re already using it to make subjective decisions. But the complex way AI grows and improves makes it hard to understand and even harder to control. In this cautionary talk, techno-sociologist Zeynep Tufekci explains how intelligent machines can fail in ways that don’t fit human error patterns — and in ways we won’t expect or be prepared for. "We cannot outsource our responsibilities to machines," she says. "We must hold on ever tighter to human values and human ethics."
Social media has changed the game for history, says Brian McCullough. Just think of all of the rich, first-hand data those posts and tweets and photos will provide to future historians.
Brian McCullough is creator of the Internet History Podcast, an oral history of the internet and its key players. Now an expert on this largely unchronicled time period, Brian is currently writing an actual book on the subject: How the Internet Happened, due to be published in fall 2017 by Liveright/WW Norton.
The TED Residency program is an incubator for breakthrough ideas. It is free and open to all via a semi-annual competitive application. Those chosen as TED Residents spend four months at TED headquarters in New York City, working on their idea. Selection criteria include the strength of their idea, their character, and their ability to bring a fresh perspective and positive contribution to the diverse TED community.
The O’Reilly Bots Podcast: Conversational interfaces for the Internet of Things.
In this episode of the O’Reilly Bots Podcast, I speak with Tom Coates, co-founder of Thington, a service layer for the Internet of Things. Thington provides a conversational, messaging-like interface for controlling devices like lights and thermostats, but it’s also conversational at a deeper level: its very architecture treats the interactions between different devices like a conversation, allowing devices to make announcements to any other device that cares to listen.Coates explains how Thington operates in a way analogous to social media; in fact, he calls it “a Twitter for devices.” Just as people engage with each other in a commons, devices chat with each other in Thington’s messaging commons. He also discusses the value of human-readable output and the challenges involved in writing human-understandable scripts.

Tim Urban knows that procrastination doesn’t make sense, but he’s never been able to shake his habit of waiting until the last minute to get things done. In this hilarious and insightful talk, Urban takes us on a journey through YouTube binges, Wikipedia rabbit holes and bouts of staring out the window — and encourages us to think harder about what we’re really procrastinating on, before we run out of time.
Food is more than nourishment. It’s a source of pleasure — and guilt — and an agent of change. This episode, TED speakers explore our deep connection to food, and where it’s headed.
