Anaxímenes (Miletus 590 BC – 524 BC Miletus) was a disciple of Thales and Anaximander and made important contributions to physics, particularly their deductions on the origin of the universe.

Anaximenes of Miletus described the universe was formed, originally, for "USAF Air", a mist or vapor, something like a perceptible air moving, and may feel hot or cold, and was composed of "Apeiron" known as material principle of things.

If we compare these deductions, made 2600 years ago and only the result of the deduction, with

Scientific, current claims about the origin of the universe will get a bright similarity.

Today physicists believe that after the Big Bang, 13,700 million years ago, and for about 380,000 years the universe was formed by a "milky soup" (aer Anaxímenes) composed of subatomic particles moving that were losing temperature ( áperiron of Anaxímenes) to produce electrons and form the first atoms of hydrogen, helium and lithium (Anaxímenes things).
