Programmable Matter

Programmable matter is matter which has the ability to change its physical properties (shape, density, moduli, conductivity, optical properties, etc.) in a programmable fashion, based upon user input or autonomous sensing. Programmable matter is thus linked to the concept of a material which inherently has the ability to perform information processing.


Conformationally Programmable Molecules

Programming a molecule, in this case a chain of carbon and nitrogen atoms as is found in proteins, by specifying rotational behaviour of individual covalent bonds as a function of time. The key is to have the first bond fixed and stationary then consider the many possibilities for specifying all the other bonds. In real life the angles between succesive bonds is not uniform or even stable but in mathematics it is standard practice to start with the simple case and work up to the more complex cases, so for now we will look at uniform angles (109.5 degrees) and bond lengths.

Geometric Properties of Freely Rotating Carbon Chains Fixed at One End

The geometric properties of the free end of a programmed carbon chain have some remarkable properties suggesting a built in code for life as we know it. Here is a recent example of the output of one such molecular program...
