The first time machines mogged mathematicians? 1976.

Proof of the ‘Four Colour Problem’ is announced, the work was aided by computer. Mathematicians lost their minds.

“God wouldn’t let the theorem be proved by a method as terrible as that!” - Herbert Wilf, University of Pennsylvania

“the present proof relies in effect on an Oracle, and I say down with Oracles! They are not mathematics” … - Paul Halmos, UC Santa Barbara

“if the solution involves computer verification of special cases . . . such a solution does not belong to mathematical science at all.” - Frank Bonsall, University of Edinburgh

“Admitting the computer shenanigans of Appel and Haken to the ranks of mathematics would only leave us intellectually unfulfilled.” - Daniel Cohen, Hunter College NYC

“not only is no proof to be found in what they published, but there is not anything that even begins to look like a proof… …It is the most ridiculous case of ‘The King’s New Clothes’ that has ever disgraced the history of mathematics” - George Spencer-Brown, Cambridge University

Our recent study about Non-Random Patterns in Adverse Life Events is "groundbreaking" according to Science Magazine. Of course it is, first author and project lead was the amazing @KyraCEvers :

Theory matters in psychological science — but where does theory in psychology currently stand?

We’re inviting psychological researchers for our survey to share their views on the state of theory.

@drmichaellevin @Yang_Supertramp Learning & developing with(in) a growing body, exploiting redundancies of reality through a limited sensory array, emergent coordination of multi-scale interactions, these seem to be overlooked as properties of intelligent agents

A massive discovery in neuroscience: fMRI signals don't always match true neural activity. In ~40% of cases, signals increased where activity actually decreased. This challenges the core assumptions of tens of thousands of studies.

New paper with Rineke Bossenbroek:

Lifelines of young people with a history in residential care: A qualitative investigation from a complex systems perspective https://t.co/pfHpaDYwpw

In which we identify patterns of change in life histories of adolescents in residential care.

Quantum mechanics has gone from a theory in test to becoming the foundation of new technologies.

@warrenmansell @IntuitMachine Interesting,, in what way is this different from direct perception, tau guidance as explanations for coordination by perception?

Philosophers who use Gödel's incompleteness theorem to make claims about "fundamental limits of human knowledge" have made a category error. It's about axiomatization, not epistemology. 1/

A plea for more rigorous theoretical guidance in clinical Early WS studies:
1) must depart from a point attractor
2) EWSs appear before the critical transition
3) EWS variables align with system destabilization

It must be some kind of holliday, another paper (also lead by @CUI_Jingmeng) out now!

This one is all bout the kind(s) of tipping we could be observing in clinical time series data!

Ik weet niet precies welke wanden @MichaWertheim gisteren heeft doorbroken in Nijmegen, maar ik werd vanochtend dus zwetend wakker op de tribune in cultuurhuis De Lindenberg.
