      “if the fundamental constants change” LOL

        well actulay some did change a (litle) bit.

        Wenn the BIMP change a defenition of a SI unit , then this can result in a “change” of a constant

        Some constants may not be constants at all.

        Some are – like the speed of light in a vacuum, but that’s by definition of the unit. A second also is constant because it’s fixed by the number of transitions between hyperfine states of Cs.

        Other constants aren’t so static – some of them have changed, and it’s likely others may change – what see as “constant” is merely “slowly changing”.

      Hi Dave,

      If it can be used as I think it can you can use it for spectroscopy or gamma ray spectroscopy. Pretty nice find!

        Though if you say it’s only got discrete signal inputs then I withdraw my comment :)

      This looks like it would be perfect for creating the famous double slit experiment.

      This box seems full of surprising gears!
