Just some thoughts to get the page started.

     3There are many physical sources of randomness and each have their own advantages and disadvantages. On this page I will explore some of these issues as a step in the design of this project. At the moment I see two primary methods for potential use by HWRNG: 
     4 
     5* Electrical (thermal) noise generated in a resistor or semi-conductor device. 
     6* Ambient radioactivity or perhaps cosmic rays. 
     7 
     8Right now I'm inclined to go with a solution involving electrical noise. However, noise sources are not usually as random as one might think and require some kind of correction or compensation to become high quality random sources.

     10Radioactive sources emit particles randomly based on a fundamental quantum mechanical process. They may require less correction than a noise generator would. However, I do not wish to include a radioactive source inside the Generator component of this project. Yet ambient radioactivity is always present and could perhaps be tapped as a random information source.
