The of invoking the notion of “purpose” is to emphasize the irrelevance of the traced by such a system en route from an arbitrary initial to its . In a synthesized system whose inner workings are known, this irrelevance has no significance. This irrelevance becomes highly significant, however when the analytic problem, the machine identification problem, cannot be solved, because, for instance, it is trans-computational in the sense that with known algorithms the number of elementary computations exceeds the age of the universe expressed in nanoseconds.

Is persistent anxiety and depression in childhood a one-way road to adverse outcomes in adulthood? nationalelfservice.net/?p=1730

In her latest blog, Laura Hankey summarises a longitudinal study using ALSPAC data that explored associations between anxiety, depression, and comorbid anxiety/depression in childhood and adverse outcomes in young adulthood.

The backward for clearly show how the air is trapped in the broad circulation of the anticyclone, descending as if in a swirl and heating.

@IvanSanchez wow, looks like you're onto something big here. I assume these trajectory animations would also work correctly around the date line?

Today European Space Agency ()'s constellation which measures Earth's magnetic field 🧭, celebrates 9 years since launch.

We used Swarm data to study . We first linked Swarm data to of migratory birds:
movementecologyjournal.biomedc

Then we developed new models of :

This is the first time anyone used data on real geomagnetic conditions to do this! And it could not have happened without Swarm.

Quick shout-out for an important and relevant to the moment paper in Trends in Cognitive Sciences:
'Trajectories of resilience and mental distress to global major disruptions' by Sarah K.Schäfer

2 key points:
1. 'Resilience is the most common response identified in most studies for most respondents'
2. 'Negative mental health consequences appear more significant for younger adults and less so for older adults.'
