Bio-mimetics From Wikipedia, the free encyclopedia

“Biomimetics (also known as Bionics, biognosis, biomimicry or bionical creativity engineering) is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology”

"taking design ideas from nature"

“Biomimetic refers to human-made processes, materials, devices, or systems that imitate nature.”

In 1959 Feynman gave his famous after-dinner talk describing molecular machines building with atomic precision

“There's Plenty of Room at the Bottom”

“The portal motor for bacteriophage f29 compresses the DNA 6,000 times its normal volume," says Bustamante. "This generates an internal pressure of about 60 atmospheres, which is about ten times that in a champagne bottle.”

Socio-political models: Examples: Bioregional Democracy

(political borders conform to natural Eco-regions rather than human cultures or the outcomes of prior conflicts)

Natural Capitalism: (Biomimicry is also the second principle of Natural Capitalism)

Genetic Algorithm

Does Nature always do an optimized job?

IKARUS Syndrome

Sub-optimality in Nature

Diversity: Many ways to the same function

Complexity:Many things to be weighted

Interact & Enjoy !!

The field of Bio-mimetics is the abstraction of a GOOD design from nature.
