There are human beings with desires of a better world and with capacity to look to the future, even in the midst of the limitations of the time.
One of them was called Francisco José de Caldas, known, with all the merits, as The Wise Caldas and born in Popayán, in the then called New Kingdom of Granada.
At a time when dealing with science was inconceivable, Francisco José de Caldas conducted research on the most varied fields of knowledge.
Caldas invented the way to measure the height of the mountains from the boiling water. And although he never recognized the merits, this invention was later applied and explained in Europe by Humboldt, who had learned it from Caldas.
Caldas studied in Ecuador the fauna and flora, the climate, the geology, measured the main heights, drew maps, and made astronomical observations.
When independence broke out, he collaborated with the insurgents by melting cannons, and making gunpowder and ammunition.
Captured by the Spaniards and condemned to death, Caldas requested that they postpone his execution for three weeks to conclude a scientific investigation. To that, the Spanish chief replied:
"Spain does not need wise people."
The Wise Francisco José de Caldas was publishing, on a day like today, the first scientific weekly in the history of America. It was a day like today, January 3, 1808. And in its first editorial it said: "All our efforts are supported by love for this land, and are destined to expand the knowledge for a life worthy of our fellow citizens."
