The wheel, a round invention
The wheel is one of the most important inventions of Humanity, a true icon of mobility. It was invented approximately 6,000 years ago in the Middle East, and in parallel it was also invented in Mesoamerica 3,500 years ago, but pre-Columbian civilizations only used it in toys. Initially it was solid wood, later the spokes […]

The wool under the microscope
Wool is a natural tissue produced by some mammals. Humans generally take advantage of sheep. In the Iberian Peninsula, the two best known sheep breeds are churra and merina. The first is very good at producing meat and milk, while the second is a good wool producer. If we mixed both races we would obtain […]
CO2 in the biosphere
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
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
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. […]
