Model 1 is patterned after the system employed under the Montreal Protocol.

Here you see four gray tiles on your left, seven gray tiles on the right.

The thermal tiles fall off.

Puzzle game based on hexagonal tiles

Complete the puzzle by matching numbered tiles

And all the tiles match up again.

The four blue tiles on the left are gray.

Disassemble a pile of tiles by removing matching pairs

This is literally the colored sequence of those tiles.

The seven yellow tiles on the right are also gray.

And we like to draw these tiles as little squares.

So, these tiles would make a complicated, self assembling checkerboard.

Where do you get lumpy tiles? Well, of course, you don't.

Clear the screen by removing groups of colored and shaped tiles

Because if they put tiles on top, it's just going to crash.

All right? Whereas on the right, the two tiles look nearly the same.

We're going to turn to another technology, called algorithmic self assembly of tiles.

We've got bubbles going up there, then suds at the top with lumpy tiles.

Here is a DNA origami rectangle, and here are some tiles growing from it.

It was work actually by Lionel Penrose, father of Roger Penrose, the tiles guy.

So if you affix some wires and switches to those tiles rather than to the staple strands, you affix them to the tiles then they'll self assemble the somewhat complicated circuits, the demultiplexer circuits, that you need to address this memory.

Then one Saturday we went to his village to visit, and his mother showed us a beautifully patterned basket made of dyed raffia that his brother had made.

That is your perceptual reality. The physical reality is that those two tiles are the same.

Whereas on the right, the information is consistent with those two tiles being under the same light.

Try to end up with the tiles in numerical order, with the space in the bottom right

We have two identical tiles, on the left, one in a dark surround, one in a light surround.

Here's the DNA origami, and what we can do is we can write 32 on both edges of the DNA origami, and we can now use our watering can and water with tiles, and we can start growing tiles off of that and create a square.

Notice that on the left the two tiles look nearly completely opposite one very white and one very dark.

Her crossing the fragmented tiles, faltering at the step to the street, droning, not looking at me, Can you help me?

He just lay in the hospital bed, and, kind of, stared at the polystyrene ceiling tiles for a really long time.

And he is a world expert in performing The Ursonate, which is a half an hour nonsense poem by Kurt Schwitters, written in the 1920s, which is half an hour of very highly patterned nonsense.

So, what we've done is we've succeeded in making something much bigger than a DNA origami by combining DNA origami with tiles.

But I get a lot of toilets, and so you just dispatch a toilet with a hammer, and then you have lumpy tiles.

And we put down those little floor tiles, and then I went onto eBay and bought 150 pounds of Lego which is insane.

It was started by Erik Winfree, and what it does, it has tiles that are a hundredth the size of a DNA origami.

And the point of this, if you didn't catch that, is that tiles are a kind of molecular program and they can output patterns.

So, you can come up with a set of tiles that when they come together, form a little binary counter rather than a checkerboard.

I'm not going to change those tiles at all, but I'm going to reveal the rest of the scene and see what happens to your perception.

You zoom in, there are just four DNA strands and they have little single stranded bits on them that can bind to other tiles, if they match.

This was just a proof of principle he did of tiles that interact magnetically, where you write a code, much like protein folding, that specifies their structure.

Without food security, individuals can have no chance of achieving social mobility. That is why we are investing in our fellow citizens by means of a conditional cash transfer program, called Pantawid Pamilya in Tagalog, which is patterned after Brazil s Bolsa Familia.

But if we use a little computation we use origami, plus some tiles that count then we can get away with using 100, 200 or 300 DNA strands.

I've kept the tiles I've kept the floors I've kept the trunking I've got in some recycled fridges I've got some recycled tills I've got some recycled trolleys.

You can see here in this time lapse video that the sun, as it moves across the surface, as well as the shade, each of the tiles moves individually.

Not finding a way to bring him in because of the multitude, they went up to the housetop, and let him down through the tiles with his cot into the midst before Jesus.
