“We have given you, O Adam, no visage proper to yourself, nor endowment properly your own, in order that whatever place, whatever form, whatever gifts you may, with premeditation, select, these same you may have and possess through your own judgement and decision […] We have made you a creature neither of heaven nor of earth, neither mortal nor immortal, in order that you may, as the free and proud shaper of your own being, fashion yourself in the form you may prefer.”
Oration on the Dignity of Man – Giovanni Pico della Mirandola

CO2 in the biosphere

published on 5.12.2019

At 464ºC Venus is the hottest planet in the Solar System, although it is twice as far from the Sun as Mercury. This extreme temperature is due to an atmospheric composition with 96% CO2, which causes an infernal greenhouse effect. On the other hand, the Earth has 0.04% of CO2 and an average temperature of […]

Lithium, a strategic element

The functions of the feather

published on 7.11.2019

Birds use feathers to fly, to keep warm and to communicate. Humans give them the same use. We improve the aerodynamics of arrows and badminton balls with feathers, fill quilts and down jackets and decorate ourselves and dress with plumes. We are plumiferous learners.

Chestnut Party and astronomy

published on 31.10.2019

The Catalan Chestnut Party and the Christian All Saints’ Day, the Halloween of the Anglo-Saxons, the Sanheim of the Celts, and the Roman Pomona festival are the same celebration with different appearance. The diversity of autumn products we consume during these days, with very diverse geographical origins, is further evidence of the syncretism of traditions. […]

Colors to highlight

published on 10.10.2019

The combination of striking colors in nature is technically known as “aposematism” and it is used by animals as a warning signal to keep predators away. It is present in the spectacular South American frogs of the genus Dendrobates, secretors of a potent cutaneous venom. Yellow and black wasps and red and black heteroptera are […]
