The lepton, plural lepta (Greek: λεπτόν, λεπτά), is the name of various fractional units of currency used in the Greek-speaking world from antiquity until today. The word means "small" or "thin", and during Classical and Hellenistic times a lepton was always a small value coin, usually the smallest available denomination of another ...
A bronze mite, also known as a Lepton (meaning small), minted by Alexander Jannaeus, King of Judaea, 103–76 BC and still in circulation at the time of Jesus [1]. The lesson of the widow's mite or the widow's offering is presented in two of the Synoptic Gospels (Mark 12:41–44 and Luke 21:1–4), when Jesus is teaching in the Temple in Jerusalem.
The name lepton comes from the Greek λεπτός leptós, "fine, small, thin" (neuter nominative/accusative singular form: λεπτόν leptón); [14] [15] the earliest attested form of the word is the Mycenaean Greek 𐀩𐀡𐀵, re-po-to, written in Linear B syllabic script. [16] Lepton was first used by physicist Léon Rosenfeld in 1948: [17]
The first issue of coins minted in 1954 consisted of holed aluminium 5-, 10- and 20-lepton pieces, with 50-lepton, 1-drachma, 2-drachma and 5-drachma pieces in cupro-nickel. 10-drachma coins of a brighter alloy were issued in 1959 and a silver 20-drachma piece was issued in 1960, replacing the corresponding banknotes.
ɒ n / M(Y)OO-on; from the Greek letter mu (μ) used to represent it) is an elementary particle similar to the electron, with an electric charge of −1 e and spin-1/2, but with a much greater mass. It is classified as a lepton. As with other leptons, the muon is not thought to be composed of any simpler particles.
The term lepton from the Greek λεπτός (meaning "Easy") may refer to: Lepton, one of the two classes of fermionic (matter) particles; Greek lepton, a small denomination of currency in Greece; Lepton, West Yorkshire, England; Lepton, a composition by Charles Wuorinen; Lepton image compression format, a computer file signature
The tau (τ), also called the tau lepton, tau particle or tauon, is an elementary particle similar to the electron, with negative electric charge and a spin of 1 / 2 .Like the electron, the muon, and the three neutrinos, the tau is a lepton, and like all elementary particles with half-integer spin, the tau has a corresponding antiparticle of opposite charge but equal mass and spin.
