Two Physics Carnivalas!

There is a second physics carnival being launched!
The first one is monthly Panta Rei (the 3rd edition will be on September 28rd), focusing on heat and flow.
The new one is called Philosophia Naturalis, with a broader theme of everything to deal with physical science and technology, and the inaugural edition is now up on Science And Reason.
The two carnivals appear to have very different concepts so it does not look like they will compete against each other.
