  • Bollire una società

    Bollire una società

    Here is how to boil a frog. Place the frog in a pan of tepid water. Raise the temperature so gradually that the frog does not realize it is being cooked. It may even fall into a stupor, as a person might in a hot bath. Eventually it will die. According to experiments done in…

  • Controproducenti

    Sadly, malaria is making a comeback in many parts of the Third World, due partly to insecticide-resistant mosquitoes and partly to complacency and political disintegration. Irrigation projects such as dams, reservoirs, and irrigation canals often work well in temperate climates. However, in tropical regions, they may backfire. They create large bodies of stationary water that…

  • Fluttuazioni

    We tend to think that the farther back we go in history, the dirtier and less hygienic people were, and so the higher the level of infectious disease. This is broadly true if we restrict ourselves to the last 1,000 years of Western civilization. However, if we consider the broader sweep of human history, the…

The valuable tree for the lumber industry was the white pine. Spruce and fir were considered “weed species.” Eventually, however, the stands of virgin…

  • I limiti dell’ingegno

    Historical evidence would indicate that very few key inventions have been made by men who had to spend all their energy overcoming the immediate pressures of survival. Atomic energy was discovered in the laboratories of basic science by individuals unaware of any threat of fossil fuel depletion. The first genetic experiments, which led a hundred…

  • Falsa competizione

    Rodney Heitschmidt and Jerry Stuth point out that “[h]umankind has historically fostered and relied upon livestock grazing for a substantial portion of its livelihood because it is the only process capable of converting the energy in grassland vegetation into  an energy source directly consumable by humans.” Nineteen billion metric tons of vegetation are produced by…

  • Cori, cori, ma ‘ndo cori?

    Un’aggiunta a quanto già calcolato. Prendiamo una distanza qualsiasi tra quelle elencate: A1 da Orte a Caserta Nord, lunghezza percorso 242,4 km. Prendiamo una tabella che dia un’idea dei consumi di un’auto di una certa cilindrata, che sia quindi capace di raggiungere i 150 km/h: ad esempio, una berlina da 1800 cc. Leggiamo che il…
