Jean-Paul Sartre is sitting at a French cafe, revising his draft of Being and Nothingness. He says to the waitress, “I’d like a cup of coffee, please, with no cream.” The waitress replies, “I’m sorry, Monsieur, but we’re out of cream. How about with no milk?”
(Remember: coffee with no milk tastes a lot worse than coffee with no cream!)
…and they shall beat their swords into plowshares, and their spears into pruning hooks: nation shall not lift up sword against nation, neither shall they learn war any more.
Organisation can emerge from chaos in complex systems made of relatively simple parts. This mathematics of emergence helps understand networks in the brain, structures in societies, and how groups of fireflies can flash in sync without requiring a leader to keep the beat. These animations show one mathematical model where runners running round a track can synchronise to the same pace with no leader. Each runner runs at their own pace, but adjusts it slightly if they feel they are slower or faster than their perceived average. [This can be succinctly written as a set of simple differential equations]. In the top row, each runner is more strongly coupled to the group than the bottom row. [The two animations on the right are the same as the ones on the left, except the camera is rotating with the group.] [more] [code]

Concluding a roaringly successful #pholenge12
We have concluded this years’ Christmas photo-challenge (#pholenge12 or #pholenge) and I have to say I’m overwhelmed by the enthusiasm and participation of all! A big THANK YOU for the great photos and for mutually motivating us to take more, better, more interesting photos! You can see the full group pool on flickr as well as a sole ranger on google+. As they say: I’m not aware of any other participants… :)
Surely at this point some statistics are in place? So here we go:
We’ve had 12 participants with a total of 128 photos submitted over course of the 16 days of the challenge, with the geo-tagged ones coming from 7 UN recognised countries (Spain, UK, Slovakia, Austria, Hungary, France and Italy). The three most active participants were iYaiza (17 photos - more than one a day! :), JoanSo2 (16) and JoanU (15) and the three most ‘liked’ photos are shown below, shot by Uergevich (11 likes), nannikn (9 likes) and again Uergevich (9 likes) - some foul play here since both are household flickr names with large fan bases :)
Finally, just because #pholenge12 is over, doesn’t mean you cannot continue submitting photos - looking forward to seeing more!
So once again thank you very much to all!
PS: If you have 3.14 minutes, I’d appreciate your thoughts on the following 3 questions:
- Would you do this photo-challenge again?
- If yes, would you do something differently?
- Would you have wanted more/less communication from the management?
