I mean the world where advanced building materials means cement roofing tiles that are made by hand, and where, when you work 10 hours a day, you're still only earning 60 dollars in a month.

And we like to draw these tiles as little squares.

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

Jamaica has a considerable amount of industrial engineering, light manufacturing, including metal fabrication, metal roofing, and furniture manufacturing.

Fire integrates everything around it sun, wind, rain, plants, terrain, roofing, fields, and everything people do, and don t do.

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

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

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

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

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.

They are given accommodation in tiny enclosures made of tin roofing and little ventilation with more workers packed into such places than sardines in a box.

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

Gone, it seems, is the heyday of T shirts, toys, plastic flowers, tiles, hooks, springs, and the like.

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

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.

Concrete objectives

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

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

Selections from the series are printed and pasted unto tiles, which are then tacked on to walls and buildings throughout San Juan.

We are concrete.

THE CONCRETE REALITY .

THE CONCRETE REALITY .

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

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

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.

Migration is a concrete example.

So concrete, transparent and efficient.

Detailed, concrete, no bureaucratic speech.

What is the concrete reality ?

What is the concrete reality ?

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.

Yet no concrete action is taken.

Concrete steps have already been taken.

The concrete measures are summarized below.

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.

It is expected to consume 10 million metric tons of concrete, the government has pledged to use only domestically produced concrete.

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.

We can ask a very concrete question.

These goals were underpinned by concrete targets.

As such, it is a concrete category.

There are concrete examples of this scenario.

Take concrete, operational steps to improve communications.

We welcome those concrete and bold proposals.
