Dido Dido (which is a question independent of whether or not she ever met Aeneas) can be associated with evidence for the historicity of others in her family, such as her brother Pygmalion and their grandfather Balazeros. Both of these kings are mentioned, as well as Dido, in the list of Tyrian kings given in Menander of Ephesus's list of the kings of Tyre, as preserved in Josephus's "Against Apion", i.18. Josephus ends his quotation of Menander with the sentence "Now, in the seventh year of his [Pygmalion's] reign, his sister fled away from him and built the city of Carthage
DIDO (nuclear reactor) DIDO (nuclear reactor) DIDO was a materials testing nuclear reactor at the Atomic Energy Research Establishment at Harwell, Oxfordshire in the United Kingdom. It used enriched uranium metal fuel, and heavy water as both neutron moderator and primary coolant. There was also a graphite neutron reflector surrounding the core. In the design phase, DIDO was known as AE334 after its engineering design number. DIDO was designed to have a high neutron flux, largely to reduce the time required for testing of materials intended for use in nuclear power reactors. This also allowed for the production of intense beams of neutrons
