This corresponds to a speed of around 0. 05 c. There is surprisingly small variation around this energy, due to the heavy dependence of the half-life of this process on the energy produced ( see equations in the Geiger – Nuttall law ).

German brass making crucibles are known from Dortmund dating to the 10th century AD and from Soest and Schwerte in Westphalia dating to around the 13th century confirm Theophilus ' account, as they are open-topped, although ceramic discs from Soest may have served as loose lids which may have been used to reduce zinc evaporation, and have slag on the interior resulting from a liquid process.

To maintain the momentum of the perceived commercial interest in this new investment opportunity, in 1983, the Government itself granted eleven interim franchises for new broadband systems each covering a community of up to around 100, 000 homes, but the competitive franchising process was otherwise left to the new regulatory body, the Cable Authority, which took on its powers from January 1, 1985.

At high redshift imaging around individual radio sources ( in this case AGN ) has been used to detect proto-clusters ( clusters in the process of forming ).

This process came to its natural conclusion with the development of the first empires around the 24th century BC.

Wells's novel revolves around an ( unspecified ) invention that accelerates the process of radioactive decay, producing bombs that explode with no more than the force of ordinary high explosive — but which " continue to explode " for days on end.
