I think PF is a very excellent physics BBS, there are many enthusiastic and professional friends to explore the magic of physics together, every physics lover is willing to contribute to the development and expansion of PF according to their ability, persistence is victory!
The road to science is full of unknown, I think it is important to adhere to the spirit of seeking truth from facts, in the exploration of the road should be bold assumptions, relax restrictions, absorb more and more physics enthusiasts, such as: UFO power, perpetual motion, anti-gravity and other aspects.
