Nanotechnology for All - Nature's Nanotechnology (Talk 4)

While we are just understanding and applying our knowledge of atomic and molecular systems (developing NT), nature has been doing this for billions of years.  Through evolution, nature has reached a state of perfection and has assembled highly complex bio-technological systems.  Many of our technological advances have come about by copying what nature has already done quietly by generating little waste and with great efficiency.

Nanotechnology for All-The Digital Revolution (Talk 5)

The modern connected world has come about due to the digital revolution over the past 100 years or so.  Before the understanding of electro-magnetic waves and the experiments of Hertz to establish their existence, communication was very limited - it was slow and only local.  Computers made a tremendous difference to the way we process information - given boost by the discovery of transistors in 1947.  Miniaturization has proceeded relentlessly since then and we are truly in the nanotechnology regime now.

It all started with Fleming...

The integration of electronic devices with biology is something that I want to address in a separate blog.  Progress in this direction has been spectacular and what the future impact of intelligent robots, artificial intelligence will be on our civilization is somewhat uncertain.
