Archelaus (philosopher) Archelaus (philosopher) Archelaus (; ; fl. 5th century BCE) was an Ancient Greek philosopher, a pupil of Anaxagoras, and may have been a teacher of Socrates. He asserted that the principle of motion was the separation of hot from cold, from which he endeavoured to explain the formation of the Earth and the creation of animals and humans. Archelaus was a philosopher of the Ionian School, called "Physicus" from having been the first to teach natural philosophy at Athens. This statement of Diogenes Laërtius, is contradicted by Clement of Alexandria, but the two may be reconciled by supposing that Archelaus
Citroën TUB were actually produced, and production of them formally ceased in December 1941. About 100 models were transformed by Fenwick in 1941–1942 to be powered by an electric engine. Probably only about 1,740 of the vans were produced, most of them being the earlier 1628 cc TUB version which may appear a poor return for the effort that Citroën committed to the project. Nevertheless, when normal life began to return after the war Citroën were quick off the mark in 1946 with the Citroën H which was in many ways a slightly larger and less aggressively light-weight version of the TUB.
