Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The charged particles polarize the molecules of that medium, which then turn back rapidly to their ground state, emitting radiation in the process. The characteristic blue glow of nuclear reactors is due to Cherenkov radiation.
Cliostraat, Open-air school for the healthy child, Amsterdam, NL, by Jan Duiker.
Though open-air schools –which emphasized welcoming, flexible spaces and access to plenty of fresh air and sunlight– from earlier in the century had been largely focused on serving sickly children, this school was for the healthy.
By deploying large windows, cantilevered concrete structures, and steel frames, Duiker designed a compact building flooded with light and air. Of his design, the architect said, “Modern techniques enable us to keep the material used in the building to a minimum and to heat these almost entirely open spaces without any difficulty so that children need only wear the lightest clothing, as is medically recommended.”
