About physicsportals.net:

There is a multitude of interesting Internet portals to physics. Remarkably, services of a number of German portals to physics almost ideally complement each other.
 
However, the strong points of a portal are not always immediately obvious.
 
The aim of physicsportals.net is to bring out,
 
which portals exist,
 
what services the individual portal offers and
 
what information need the individual portal meets.
 
Thus, physicsportals.net presents an user-friendly entry point to physics information and services bringing together resources of different type and origin.
