Some atoms are unstable and will undergo radioactive decay. When this happens, they emit ionizing radiation are often transformed into another element. This article explains how to calculate rates of radioactive decay. Atoms which are prone to radioactive decay are known as radionuclides. Radionuclides can occur naturally, or can be man-made â such as during the fission process in a nuclear reactor.
Sir Francis Drake with his new heraldic achievement, with motto: Sic Parvis Magna, translated literally: Thus great things from small things (come). The hand out of the clouds is labelled Auxilio Divino, or With Divine Help.
Re: definition of Magna please. I'm not sure, but i think Magna means greater and Parva means lesser. Magna i'm almost sure due to Magna Carta - Great Charter. I think these prefixes were introduced by the Normans - thats why they are usally only found in the south and in some parts of the Midlands.
