Chernobyl – Tschernobyl
Today marks the 30th anniversary of the nuclear catastrophe in Chernobyl.
McClatchy DC: Ruined Chernobyl nuclear plant will remain a threat for 3,000 years. “30 years since Chernobyl may seem like a long time, but it’s really just the start. Below reactor’s ruins is a 2,000-ton radioactive mass that can’t be removed. How do you protect a site for as long a time as Western civilization has existed?”
Radio Free Europe / Radio Liberty: The Chernobyl Disaster: How It Happened. “On April 26, 1986, a routine safety test at the Chernobyl nuclear power plant in Ukraine spiraled out of control. Follow the dramatic events that led to the world’s worst civilian nuclear disaster.”
Links via the 30th anniversary commemoration thread on MetaFilter, which contains more excellent links and interesting discussion, as usual: “This was the day, of course, when we learned we were wrong.“
I posted about Chernobyl on my weblog several times in the past: April 26, 2006, 20th anniversary; May 2, 2006, Artikel aus der Zeit; May 28, 2007; April 26, 2010; November 18, 2010.
Wildlife in Unlikely Places
Boston Globe: The Big Picture: Wild Chernobyl.
“What happens to the environment when humans disappear? Thirty years after the Chernobyl nuclear disaster, Reuters photographer Vasily Fedosenko documented booming populations of wolf, elk and other wildlife in the vast contaminated zone in Belarus and Ukraine. On April 26, 1986, a botched test at the nuclear plant in Ukraine, then a Soviet republic, sent clouds of smouldering radioactive material across large swathes of Europe. Over 100,000 people had to abandon the area permanently, leaving native animals the sole occupants of a cross-border “exclusion zone“ roughly the size of Luxembourg.”
(I thought the English word for Elch was moose, but it turns out that it’s the American species. The European species is called elk.)
Fundstück für Physiklehrer
Peter Lingemann hat auf seiner Homepage Uranmaschine.de alle möglichen Materialien und Quellen für Physiklehrer zusammengestellt, u. a. Experimente, didaktisches Material, Hilfreiches zum Einsatz von Geräten zur digitalen Messwerterfassung in der Schule…
Die Seite kannte ich schon länger, aber erst gerade eben habe ich realisiert, dass ich den Autor durch einen Artikel aus Praxis der Naturwissenschaften – Physik in der Schule kenne. Dort hat er einen Artikel zur Umgestaltung von Physikräumen veröffentlicht: Ohne Pult aber wieder mit Kreidetafel. Dieser hat mir weitergeholfen, als ich vor einiger Zeit mit meiner Physik-Fachschaft die Umgestaltung unserer Physikräume geplant habe, die im Rahmen der bereits laufenden Sanierung meiner Schule stattfinden soll. Für alle Physiklehrer lesenswert – der Artikel und Uranmaschine.de!
