Splitting Definition and 259 Threads

Wood splitting (riving, cleaving) is an ancient technique used in carpentry to make lumber for making wooden objects, some basket weaving, and to make firewood. Unlike wood sawing, the wood is split along the grain using tools such as a hammer and wedges, splitting maul, cleaving axe, side knife, or froe.

    Calculating Magnetic Splitting: delta E and Visible Lines

    For a field of 15 T, I calculated the magnitude of the splitting, which was 1.391E-22 J (this is delta E), i.e. delta E = |e| / 2m hbar B_z (m2 - m1) where m2 and m1 are the m_l levels. In order to determine the spacings for the visible lines on the absorption spectra, will that just be...

    Splitting and stepping down voltage

    I'm currently attempting to design a circuit that can step down an 18.5V lipo battery into independent voltages of 12V and an indeterminate number of 5V lines, which will be powering various pieces of equipment. At this point I'm still pretty much in the early conceptual stages, so I'm not too...

    Understanding Vacuum Rabi Splitting in QED Cavities

    I am studying a little about QED in a cavity. I don't really understand Vacuum Rabi splitting. The way I see it, it is the effect on a cavity's transmission spectrum of an atom (or quantum dot) inside the cavity. Well, this leads to two questions: 1) why is the cavity's transmission spectrum...

    How Does Partial Fraction Decomposition Apply to Laplace Transforms?
