My most fundamental piece of theory

I am returning, for a while, to what seems to be my most fundamental piece of theory, which I developed in my article ‘Settlement by Energy – Can Renewable Energies Sustain Our Civilisation?’. I take on studying two specific cases: United Kingdom and Saudi Arabia. They are two very different social environments. Read more at , or at

Making my brain dance to a slightly different tune

This is one of those putting-order-in-things updates. I am carefully reviewing the distinctions I have nailed down, so far, in my business plan for the EneFin project. From a different angle, I am progressively wrapping my mind around developing educational content for the next academic year. Read more at

And so I ventured myself into the realm of what people think they can do

I carry on reviewing the literature pertinent to behavioural economics and behavioural experiments regarding economic decisions. I am prancing a bit between Charles Darwin, Thorstein Veblen, and Gerd Gigerenzer. Read more at , or at

The dashing drip of Ketonal, or my fundamental questions for the New Year

I am in a mood for asking fundamental questions. This is how I see business, and this is how I apprehend my life: by figuring out what are the best questions to ask. Read more at , or at

Deux intelligences alternatives

J’applique un réseau neuronal de plus en plus élaboré à l’étude de l’efficience énergétique. J’en suis arrivé au point où je peux dire en toute confiance : si nous imposons à une structure intelligente des conditions logiques différentes, elle va se développer dans des directions complètement différentes. Au-delà de ma recherche sur l’énergie, je me pose de plus en plus souvent des questions fondamentales. Si nous changeons les assomptions logiques de notre civilisation, où est-ce que ça peut nous mener ? Lisez plus sur

What can be wanted only at the collective level

I am entering a phase in my work, when I need to combine science writing with preparing new online content for the new academic year of teaching. This update is a good illustration thereof: a little bit of science and a little bit of teaching ideas. Read more at

The perfectly dumb, smart social structure

I am experimenting with an artificial neural network, in order to give some depth to my thinking about the emergence of new social roles in cities, and about the role of cities as cradles for new social roles. I simulate the behaviour of a social structure in the presence of an external disturbance, e.g. rapid technological change, pandemic etc. Besides the easily predictable, alternative scenarios of social change, two really surprising observations emerge out of that experiment. Firstly, when social cohesion looses up, some social roles tend to disappear, but they kick back into existence shortly after. Secondly, and more generally, social roles do not really disappear under the impact of external stressors: they rather go dormant and can come back. Read more at

Did they have a longer breath, those people in the 17th century?

Here comes an update when I go freestyle intellectually, and I digress a bit on one of my favourite readings, ‘The Perfect Merchant’, or ‘Le Parfait Negociant’ in its French original, written and published by Master Jacques Savary in 1675, when d’Artagnan died. Read more at
