Fahrrad: Wundermaschine der Mobilität
100 Kilokalorien reichen einem Radler, um etwa fünf Kilometer zurückzulegen. Ein Auto schafft mit dieser Energie allenfalls 85 Meter. In der Stadt ist das Fahrrad auf Strecken bis fünf Kilometer das schnellste Verkehrmittel der Wahl - und es schenkt Fahrern dabei Freiheits- und Glücksgefühle. 30 Prozent der Autofahrten ließen sich durch das Fahrrad ersetzen.
Bicycle for the Mind
I read a study that measured the efficiency of locomotion for various species on the planet. The condor used the least energy to move a kilometer. And, humans came in with a rather unimpressive showing, about a third of the way down the list. It was not too proud a showing for the crown of creation. So, that didn’t look so good. But, then somebody at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle. And, a man on a bicycle, a human on a bicycle, blew the condor away, completely off the top of the charts.
And that’s what a computer is to me. What a computer is to me is it’s the most remarkable tool that we’ve ever come up with, and it’s the equivalent of a bicycle for our minds.
