this is not ASPS main page. I’m not directly involved to the development of PNN. Everything you will find here is free material released online by ASPS. Even if you’ll find some formulas and concepts here I’m not a physicist , just a curious, so please be kind to any imprecision.
If you are interested in PNN development, please contact ASPS at:
In the links section you can find the links to the main ASPS related sites. The list is in continuous update.
This website is openly pro-PNN and supports ASPS in its decisions.
