sighted writes "In one of the more remarkable shots ever taken by robotic space explorers, the Opportunity Mars rover has been photographed by the Mars Reconnaissance Orbiter ." From the article: "Shown in the image are 'Duck Bay,' the eroded segment of the crater rim where Opportunity first arrived at the crater; 'Cabo Frio,' a sharp promontory to the south of Duck Bay; and 'Cape Verde,' another promontory to the north. When viewed at the highest resolution, this image shows the rover itself, wheel tracks in the soil behind it, and the rover's shadow, including the shadow of the camera mast. After this image was taken, Opportunity moved to the very tip of Cape Verde to perform more imaging of the interior of the crater."
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
