Смерть — когда все мысли можно очертить окружностью с радиусом Шварцшильда.

Смерть — это когда все мысли вписываются в радиус Шварцшильда.

Сейчас меня занимает мысль на сколько корректно говорить "вписываются в радиус"... А ты что думаешь по этому поводу, юзернейм?

Телескопы на воздушных шарах, проект «Stratoscope»

http://en.wikipedia.org/wiki/Stratoscope

The Stratoscopes were two balloon-borne astronomical telescopes which flew from the 1950s to the 1970s and observed in the optical and infrared regions of the spectrum. Both were controlled remotely from the ground.

Stratoscope I possessed a 12 inch (30.48 cm) mirror and was first flown in 1957. It was conceived by Martin Schwarzschild and built by the Perkin Elmer Corporation. A small secondary mirror focussed the image from the primary into a 35 mm movie camera, which captured the images on film. Schwarzschild used the telescope to study the turbulence and granulation in the Sun's photosphere.

Stratoscope II, a 36 inch (91.4 cm) reflecting telescope, flew from 1963 to 1971. The gondola it was mounted on weighed 3.5 tons. It studied planetary atmospheres, the atmospheres of red giant stars, and galaxies. On early flights of Stratoscope II, photographic film was used, but this was soon replaced by television detectors.
