Two examples

The Pantheon – Rome

Then the recipe for Concrete was lost

We need bundles of nanotubes

Defects will not propagate among the straws

We need to make them meters long

Man’s greatest Enemy

2.7 million deaths this year

The embargo on DDT has condemned 2.7 million (mainly children) to death this year

Bio-Nano approaches DNA manipulation

We need to make them meters long

We need bundles of nanotubes
