La matière selon Aristote


"Au contact d'une chaise, Aristote, Newton; Einstein et Bohr éprouveraient sans doute les mêmes sensations. Mais leur conception de ce qui compose cet object quotidien serait fort différente. Retour sur 2500 ans d'évolution dans la connaissance de la matière."
Román Ikonicoff,

Note: Pour Aristote, une chaise, comme tout objet matériel, est composé de quatre éléments: eau, terre, feu et air.

The concept of universities

I have always liked the concept of universities as they were in Ancient Greece, where folks who had something cool to say would just come and say it. It wasn't about recognition; the impetus was the thought that you were resonating with ideas. Donald E. Knuth

Charting culture

Note:  This animation distils hundreds of years of culture into just five minutes. A team of historians and scientists wanted to map cultural mobility, so they tracked the births and deaths of notable individuals like David, King of Israel, and Leonardo da Vinci, from 600 BC to the present day. Using them as a proxy for skills and ideas, their map reveals intellectual hotspots and tracks how empires rise and crumble. The information comes from Freebase, a Google-owned database of well-known people and places, and other catalogues of notable individuals. The visualization was created by Maximilian Schich (University of Texas at Dallas) and Mauro Martino (IBM).
