The Manhattan Project may have never come to fruition if it wasn’t for that one German physicist: Otto Hahn. Hahn‚ working with Fritz Strassmann‚ discovered that when uranium was bombarded with neutrons a radioactive barium isotope was among the products. Hahn immediately realized the importance of this and told one of his colleagues (who had fled Germany due to nazi racial laws)‚ Lise Meitner‚ about his findings. Lise worked with her nephew Otto Frisch to replicate

important to know the intended use of the data. For soil classification purposes‚ a soil’s CEC is often measured at a standard pH value. Examples are the ammonium acetate method of Schollenberger and Dreibelbis (1930) which is buffered at pH 7‚ and the barium chloride-triethanolamine method of Mehlich (1938) which is buffered at pH 8.2. Such CEC measures can result in values very different from the CEC of
