What that means is prepping my outfit, (Laughter) prepping options, trying to figure out what I'm coming behind and going in front of.

Before I start that, just so you know, each time we go to a place, we don't have authorization, so we set up like commandos -- we're a group of friends who arrive there, and we try to paste on the walls.

A lot of kids these days like to play games, but now they want to make them, and it's difficult, because not many kids know where to go to find out how to make a program.

So the wish was pretty simple: we just put up a website and you can send us your photo for whatever you believe in or whatever you want to fight for; we'll send you back your photo in large format, wherever you are in the world.

I had no idea what I was doing, I had no idea where I was going, but at some point, I stopped -- when to keep going would seem like I was going too far.

The visualization you see forming behind me is called Collusion and it's an experimental browser add-on that you can install in your Firefox browser that helps you see where your Web data is going and who's tracking you.

So I'm not going to go through the whole details of the study because actually you can read about it, but the next step is observation. So here are some of the students doing the observations. They're recording the data of where the bees fly.

On the other hand, when our minds wander, they're unconstrained. We can't change the physical reality in front of us, but we can go anywhere in our minds.

Today I'm going to show you an electric vehicle that weighs less than a bicycle, that you can carry with you anywhere, that you can charge off a normal wall outlet in 15 minutes, and you can run it for 1, 000 kilometers on about a dollar of electricity.

So they're modular reactors that are built essentially on an assembly line, and they're trucked anywhere in the world, you plop them down, and they produce electricity.

Well, in this case, this spherical magnet acts like a 3D pixel in our space, which means that both computers and people can move this object to anywhere within this little 3D space.

I was really struck by the symphony of subtle sounds all around me in the city that you can hear and work with to understand where you are, how you need to move, and where you need to go.

Similarly, just through the grip of the cane, you can feel contrasting textures in the floor below, and over time you build a pattern of where you are and where you're headed.

And when I interviewed her about that experience some years later -- she's a poet and psychotherapist named Maggie Robbins -- when I interviewed her, she said, "I was singing 'Where Have All The Flowers Gone, ' over and over, to occupy my mind.

That allows sort of a warrantless wiretapping, mass surveillance of the entire country's phone records, things like that -- who you're talking to, when you're talking to them, where you traveled.

LP: Well, I guess, in thinking about where we're going -- you know, why is it not done? -- a lot of it is just computing's kind of a mess.

And then I suddenly realized that it absolutely didn't matter where I was going, or where I had come from because we are all essentially permanently displaced people.

I ventured on my two-year, 27, 000 mile journey to learn where, why, and how white people are fleeing, but I didn't expect to have so much fun on my journey.

Since September the 11th, when my work on Islam suddenly propelled me into public life, in a way that I'd never imagined, I've been able to sort of go all over the world, and finding, everywhere I go, a yearning for change.

By definition, it means the particles are essentially locked into place and must push back instead of getting out of the way, but water is liquid and flows easily.

Rather than simply swishing by all the teeny, tiny molecules, now every single water molecule is like another person you have to push past to get anywhere.

I made a vow that from now on, every time one of my children asks me to play, no matter what I'm doing or where I'm going, I say yes, every single time.

It can take a second for an email to go around the world, but it can take days or weeks for money to move through the banking system across a city.

And she's right. Every time you go there, you know that if you actually need critical care -- critical care of any sort -- if you have an accident -- of which there are many, there are accidents everywhere -- where do they go?

When I go back home -- and I do all kinds of things, I teach, I train -- but I catch one of these things, or I'm chronically ill with one of those, where do they go?

What she said and what I've learned from others is that we do not make the so-called decision or choice to die by suicide in the same way that we choose what car to drive or where to go on a Saturday night.

So, it's fairly easy -- If you say I'm going to be really good at one specific route, that's one thing, but it should be able to go, really be very good, certainly once you enter a highway, to go anywhere on the highway system in a given country.

(Applause) Those simple capabilities mean that people can go almost anywhere on earth, on any kind of terrain.

Every couple of years, I head off to wherever the moon's shadow will fall to experience another couple minutes of cosmic bliss, and to share the experience with others: with friends in Australia, with an entire city in Germany.

All you need is a wearable computer, a pair of smart glasses, and you can take your emails and your spreadsheets with you wherever you go.

Then you zoom in to the state level, and you can begin to tell who's got leukemia, how did they get leukemia, what kind of leukemia do they have, what shifted from what place to what place.

They live in a three-dimensional world where there is no difference in energy between going this way, that way, that way or that way.

Over interdimensional radio, your engineers explain that the robot can teleport into the alternate universes you’re trapped in, but it’ll do so completely at random.

Without a restoration story that can tell us where we need to go, nothing is going to change, but with such a restoration story, almost everything can change.

So we're going to look at some maps of the past, the present and some maps you haven't seen in order to get a sense of where things are going.

And so we have to understand not only why tech's important, where it's going, but also, very importantly, when -- the timing is everything.

So, what I'm going to tell you today, is a little bit of why I think that's the case, and then go out of my comfort zone and tell you where I think it's going, where a new approach -- that we hope to push forward in terms of treating cancer.

And the best part is that, while you use a costly non-stick pan, you eat the so-called Teflon or Teflon-like material because after some time the stuff disappears. Where has it gone?
