Pere Renom

“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

The pig, everywhere

published on 14 11 2019

November 11 is Saint Martin’s Day, traditionally the day of the pig slaughter. It is always said that the pig takes advantage of everything: we eat the fresh or cured meat in the form of hams or sausages, the skin and the fat in the form of crusts, but we also tan the leather, from […]

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. […]

Animal speed

On October 12, 2019 the Kenyan Eliud Kipchoge managed to break the 2h barrier and finish the marathon in 1h 59’and 40″. The athlete ran through an urban circuit in Vienna, and had the help of other 41 athletes that acted as pacemakers (called “hares” in many countries). He was able to maintain a stratospheric […]

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 […]

The story of the hand

published on 3 10 2019

The story of the hand goes back to the origin of terrestrial vertebrates, between 390 and 340 million years ago. In those times, some fish ventured to colonize the terrestrial environment and the first amphibians emerged. Those animals had 6, 7 and up to 8 fingers on each leg, but they ended up becoming extinct […]

Cows and climate change

published on 26 09 2019

The cow is a ruminant animal and has 4 stomachs: the rumen, the reticulum, the omasum and the abomasum. The first two have a rich community of microorganisms that ferment the vegetation in anaerobic conditions, that is, without the presence of oxygen. Some of these microorganisms, the so-called archaea or archaebacteria release methane gas. This […]

Edible flowers

published on 19 09 2019

In our usual diet we incorporate many more flowers than we think. Let’s look at an exemplary menu. Initially we will prepare a salad with zucchini flowers. We can also add raw broccoli. Broccoli is a perfect example of fractal structure. Mathematicians speak of fractality when they find a geometric pattern that is repeated at […]

Artificial teeth

published on 12 09 2019

The human denture is typical of an omnivorous animal, therefore, it is not specialized. If we compare it with the typical denture of two carnivores, a dog and a cat, we will see that both have very developed fangs. These teeth serve to kill the prey and tear the meat. Humans have incorporated meat into […]

Hexagons in nature

published on 5 09 2019

The street called “Passeig de Gracia” in Barcelona is partially paved with hexagonal tiles designed by Gaudí, and they have become so famous that are even exhibited at the MoMa in NY as the first example of industrial design. One of Gaudí’s most famous phrases was “to be original is to return to the origins”. […]
