Si impara a riciclare la carta. La maestra Laura della scuola Rudolf Steiner di Origlio insegna la tecnica a un gruppo di genitori, nonni e amici delle elementari di Cuasso. Ci si ritrova tutti insieme sabato 2 marzo con tutto l’occorrente per provare a realizzare fogli di carta da vecchi giornali. Al termine della mattinata il gruppo è pronto per insegnare ai bambini, classe per classe.
I thought "boy you know you're a bike nerd when you mistake an "Element" shirt for one that says "Clement Tubulars."
On the other hand, it's a dead-on copy of the Clement script.
Irony? Or piracy? You decide. www.yellowjersey.org/strttyel.jpg
Actinium (Ac) is # 89 on the Periodic Table of Elements. Elemental actinium is a silvery-gray metal. Thirty-four isotopes of actinium are known - all are radioactive. Three occur naturally in trace amounts as decay products in radioactive minerals: actinium-225, actinium-227, and actinium-228.

Carbon (C) is # 6 on the Periodic Table of Elements. It forms by late-stage nuclear fusion in certain types of stars. Elemental carbon takes various forms that range from a soft, dark silvery-gray, metallic-lustered material to a very hard, variably-colored, adamantine-lustered material. The former is the mineral graphite and the latter is diamond. Fourteen carbon isotopes are known - three occur naturally. Carbon-12 is common, carbon-13 occurs in low abundances, and carbon-14 is a natural, radioactive variety that occurs in trace amounts.
Seen here are graphite (= cube), diamond & raw diamond, graphene, carbon nanotubes, and buckminsterfullerene (C-60).
