Theodore von Kármán (1881–1963) was a Hungarian-American mathematician, aerospace engineer and physicist who worked in aeronautics and astronautics. He was responsible for crucial advances in aerodynamics characterizing supersonic airflow. The human-defined threshold of outer space is named the Kármán line in recognition of his work. This 1959 photograph shows von Kármán (left) joined by United States Air Force and NASA officials while inspecting two missile models used in the high-velocity, high-altitude wind tunnels at Arnold Air Force Base. The missiles shown are the AGARD-B and the Atlas Series-B.

The Alpine ibex (Capra ibex), also known as the steinbock, is a species of goat that lives in the Alps of Europe. Its closest living relative is the Iberian ibex. They have brownish-grey coats and sharp hooves adapted to steep, rough terrain. Found at elevations as high as 3,300 metres (10,800 ft), they are active throughout the year, primarily feeding on grass in open alpine meadows. Adult males, which are larger than the females, segregate from them for most of the year, coming together only during the breeding season, when they fight for access to the females using their long horns. The Alpine ibex has been successfully reintroduced to parts of its historical range, but all individuals living today descend from a population bottleneck of fewer than 100 individuals from Gran Paradiso National Park in Italy. The species has few predators and is not threatened, but it has very low genetic diversity. (Full article...)
