Physicists studying complexity theory call a sudden shift from one network structure to another a phase transition. Make a few small changes in the links between a few nodes, and suddenly the whole network structure is different.

The Minister may be trying to achieve some form of tipping point of his own with his network reviews, but as I have pointed out, I ain't ever going to vote for Labour under its current management. And I am trying to do my level best to convince all around me to follow suit. And if everyone against school closures does so as well, we may reach our own tipping point and save our schools!
