Transcript of Emergence 2


"Emergence is the way complex systems and patterns arise out of a multiplicity of relatively simple interactions"

David Tinker-
"A system may be said to possess "emergent properties" when
(a) it is composed of a collection of entities,
(b) it has global properties, ...
that arise from additive combinations of local interactions among the entities."
Stephen Hawking -
"The 21st century will be the century of (emergent) complexity"
Everything breaks down
Falls apart
Living things grow old and die...
Many People think that the Laws of Nature tell us that
But what about...
The Emergence of Life
The Complexity of Life
Is this rare and miraculous...
or could it be that Complexity is inevitable...
following natural laws we have
yet to discover.
Or more simply...

It's Order that we wouldn't expect
We understand order when there is a conductor...
Order is intuitive to us when it comes from the Top-down
We understand order when there is a General
Simple rules for the Birds
- Stay close to other birds
- Not too close
- Stay away from predators!
Complex behavior of the flock emerges

The whole is more than the sum of it's parts
It's organized from the Bottom-Up
But what about...
Human brain: 100 Billion Neurons, each connected to 10 000 others!
Modern computer chips have about 500 million transistors, each connected to 10 others at most
Arthur Samuel
Wrote a checkers program in the early 1950's

Out of the interations of transistors following
Samuel's simple rules...

Emerged not only the complexity to play checkers

But to learn from it's opponents.
Can anyone think of any other examples of emergent behavior?
Emmergence aims to study how complex patterns
can arise from the interactions of simpler parts
Sand, water, birds, transistors, neurons, humans
Meandering Rivers
Logic, Learning
Closing Point:

Life is more than emmergence of complexity...

The Universe spontaneously creates complex patters
on its own.

Life arose when an emergent pattern came to be that could
replicate itself, and the replicated patterns could compete for survival.

Whenever we look at life, we are looking at emergence.
