    Lurking in my recent research readings, this is a problem at the intersection of middle school geometry and quantum chaos …

  • FW’s Notebook #0 – Opening and Big CIRCLE GEODESICS

    Putting the iPad to the same good use, but publicly.

    Summer is beginning, and my first three years of formal college education has come to an end. During this period, I have perfected the skills of Googling for good questions and solutions on a variety of subjects, *rarely* for homework, and for self-study.

    It’s time to contribute too. New physics / maths blog posts in handwritten formats coming weekly. If there’s time to spare LaTeX things are possible as well.

    Question #0

    Q0. Show that the shortest path between two points on a sphere is the big circle.

     a familiar exercise.

  • For Trees

    What’s left is long buried:

    Roots in the dark,
    stories dissolving—
    pressure in every vesicle,
    between the soil
    and all the sky reachable.

    They were the stage,
    the actor,
    the playwright.

    A barren terrace
    slowly grows its cover;
    shuffling sunshine
    weaves the shape.

    What’s left is long buried:
    lumber from the hill—
    to build,
    for fuel,
    material ideal.

    I pray
    to the storm,
    to the fire.

    I pray
    to the axe,
    to the hand,
    to the eyes.

    Be kind
    to the souls of a giant,
    to the bones of time.
