    1. Control rods are usually used in control rod assemblies (typically 20 rods for a commercial PWR assembly) and inserted into guide tubes within a fuel element. A control rod is removed from or inserted into the central core of a nuclear reactor in order to increase or decrease the neutron flux, which describes the number of neutrons that split further uranium atoms. This in turn affects the thermal power, the amount of steam produced and hence the electricity generated.

    1. The Sun's high circulation was made possible by its use of steam-powered printing presses. Such presses, which had only recently become available, allowed papers to print tens of thousands of copies at a cheap rate, thereby broadening their readership and turning them into a medium of truly mass communication. In addition, the Sun used an innovative means of distribution that further broadened its reach — newsboys who sold issues on the street, shouting out the headlines for everyone to hear. The Sun was the first paper anywhere to use newsboys to sell copies. It had started using them in 1833, less than two years before the moon hoax, so their presence on city streets was still a relatively new part of the urban environment.
