    Notes: [Auszug] THIS book tells the story of the rapid growth of research in physics in the National Research Council laboratories in Ottawa before 1953. They began in 1929. Like the National Bureau of Standards in the United States and the National Physical Laboratory in the United Kingdom, they became the home ...

    Notes: [Auszug] "NUCLEAR power is complicated, but not that complicated. The basics are fairly simple. Anyway it's not just a question of techniques or economics. It's about the kind of society we want for ourselves and future generations". It really is strange the way nuclear power is inflated into the position ...

    Notes: [Auszug] THIS is a very welcome book - for what it provides, what it suggests and what it makes possible. What it provides is a classification scheme and history of frictional electrostatic machines, devices which constituted the first important electrical invention. Together with the Leyden jar, they made ...

    Notes: [Auszug] Interpreted under the assumption of ionisation equilibrium, the X-ray spectrum of Pup A consists of two components which have temperatures of 13 and 2.5 x IO6 K (rf. 2). Therefore, if ionisation equilibrium indeed holds, the low-temperature plasma should emit [Fe xiv] 5,303 A photons as observed in ...

    Notes: [Auszug] The technique of recombining DNA from a foreign source into a host organism could have harmful consequences only after a sequences of events, if at all. An organism must escape from the containment facility, there must be another living system present, the living system must become infected, and ...
