Tractors, from the mule to the microchip
Since its inception agriculture had several technological revolutions, which have always gone in the direction of saving effort and increasing efficiency: animal traction, mechanization, precision and interconnection. Only robotics is lacking, and the farmer will not have to move a single finger to work in the field. The following spoke: Jordi Terrazas, Equibru, Joan and […]
Tempus fugit
Time is an unattainable dimension. We live within the time from birth, and it structurates our lives. We have learned to measure it with nanosecond precision in atomic clocks, but we are still experiencing it subjectively. Einstein showed that time is relative and, apparently, on a cosmic scale could be slowing down until stop it. […]
The engine wide
What makes a car “has nerve” as a Formula 1? ABS, ESP … What do these acronyms? When the first car was manufactured? What does an engine inside? The reporter Pere Renom rides a motor piece by piece, visits the SEAT testbed and get a practical lesson in safe driving circuit.
Gaudí and the natural forms in the Sagrada Família
To better understand the relationship between the architecture of Gaudi and the nature, the biologist Pere Renom climbs the canopy of a beech forest over 40 meters high and compare the structure with that of the central nave of the Sagrada Família, designed like a forest of stone. The hyperboloid domes topping the nave are […]
Undressing the laundry
The perfect laundry is a challenge for physics, chemistry and for the reporters of Quèquicom, who learn the best tricks to get an immaculate clothes. How is it possible that the soap used to clean fats, is in fact obtained from fats? What is the difference between soap and detergent? How to use the bleach?
The bicycle: a perfect machine
“Quèquicom” explains why the bicycle is a perfect machine. Consumes 40 times less than the car, and its manufacturing saves 100 times energy. It is also the fastest urban transport in distances of less than 8 km. And in addition, cycling is a healthy pleasure.
