A private website treats my current activities. 
I store my papers at an e-print archive.
I use docs.com to promote my papers.
To investigate the foundations and the lower levels of physical reality Hans started in 2009 a personal research project that in 2011 got its current name,"The Hilbert Book Model Project".
The Hilbert Book Model is a purely mathematical unorthodox and controversial model of the foundations and the lower levels of the structure of physical reality.
