Urak ez du 0°C-tan zertan izoztu
Berriki egindako esperimentuan, Utah-ko Unibertsitateko (AEB) ikerlari talde batek ura –48ºC-ko tenperaturan egoera likidoan mantentzea lortu zuen. Hortik behera ura bat-batean izoztu zen, baina nola lortu zuten tenperatura horretan ura egoera likidoan egotea?
Ura 0ºC-tik behera egoera likidoan mantentzen dena, kasu ugari topa ditzakegu naturan; lainoan, adibidez, inguruko airearen tenperatura gradu askotan negatiboa izanik ur-tantak topa daitezke. Gakoa uraren purutasun-mailan datza, hau da, uretan normalean dauden ezpurutasunek (gatzak, hondarrak, eta abar) eragiten dute urak 0ºC-ren inguruan izoztea. Zenbat eta ur puruagoa izan orduan eta izozte-puntu baxuagoa lortuko da; Utah-ko ikerlariek –48ºC-tan finkatu dute, oraingoz, izozte-tenperatura.
Ez dirudi aplikazio praktiko izugarririk izango duenik saiakera honek, baina gutxienez, hobeto ulertuko dugu zergatik, batzuetan, euri-urak lurra ukitzean bat-batean izozten diren.
From linguistics or glotophobia and, of course, hatred against Basque, we have often seen our Basque become the dandruff of all sticks. Last of all, the president of Kutxabank, Anton Arriola, has been shaking our language and giving us galantas.The President of Kutxabank,

Do not look for this connection from Ezkio or Altsasu, let alone crossing the Ebro River through Castejón. The connection, or rather the connections, between the Basque Y and the AVE of Navarre is already a reality. It is these links in the plural that should concern us and... [+]
Don't make a fuss, don't confront, don't victimize... and obey. As oppressed subjects, in this case as Basques, we talk, how many times have we had to listen to them? Ironically, two years ago, at the Euskalale Independentiston Meeting, Esne Arzallus said: "We have arrived here,... [+]
