An Upper Limit for the Electron Antineutrino Mass from Tritium β-Decayed into a thin layer of carbon. The neutrino mass determined is consistent with zero with an upper limit of 18 eV/c., which includes instrumental and statistical uncertainties as well as uncertainties due to energy loss in the source and the final electronic states. This result is in contradiction tAffable 发表于 2025-3-26 02:58:34

G. Gelminied by the spirit of Dr. Janusz Korczak, a well-known pediatrician in charge of an orphanage in the Warsaw Ghetto. Although he had repeated offers to leave the Ghetto and flee to the safety of the Aryan side of Warsaw, Korczak denied each opportunity, refusing to abandon the orphans. During the depor
