Chemical element of metals. Cu comes from Cuprum, Fe comes from Ferrum, Ag from Argentum. The symbols were not followed by a period (full stop) as with abbreviations. Later chemical elements were also assigned unique chemical symbols, based on the name of the element, but not necessarily in English. For example, sodium has the chemical symbol 'Na' after the Latin "natrium". The same applies to "W" (wolfram) for tungsten, "Fe" (ferrum) for iron, "Hg" (hydrargyrum) for mercury, "Sn" (stannum) for tin, "K" (kalium) for potassium, "Au" (aurum) for gold, "Ag" (argentum) for silver, "Pb" (plumbum) for lead, "Cu" (cuprum) for copper, and
CU Spaceflight offer to do so, hoping to raise the profile of engineering and aerospace in particular. During the 2007 Cambridge Science Festival, CU Spaceflight launched their Nova 5 balloon in front of a large crowd. CU Spaceflight CU Spaceflight is a student-run Cambridge University society founded with the aim of achieving cheap access to space. It is supported by the Cambridge-MIT Institute. The project was founded in the summer of 2006, with the specific goal of launching a rocket into space for less than GBP£1000. As of November, 2007, CU Spaceflight has launched five uncrewed high-altitude balloons, of which two were
