    am i lonely?

    im not even sure i know what being lonely really is? am i happy? im not really sure. according to most that is clearly a sign i am not. but im just not sure.

     
  3. Dallas, TX -> San Francisco, CA -> Atlanta, GA -> Richmond, VA

    Reminds me how much I hate flying on planes, and not being able to drive a car.

    But damn if it hasn’t been worth it so far.

The hummingbird has long been admired for its ability to hover in flight. The key to this behavior is the bird’s capability to produce lift on both its downstroke and its upstroke. The animation above shows a simulation of hovering hummingbird. The kinematics of the bird’s flapping—the figure-8 motion and the twist of the wings through each cycle—are based on high-speed video of actual hummingbirds. These data were then used to construct a digital model of a hummingbird, about which scientists simulated airflow. About 70% of the lift each cycle is generated by the downstroke, much of it coming from the leading-edge vortex that develops on the wing. The remainder of the lift is creating during the upstroke as the bird pulls its wings back. During this part of the cycle, the flexible hummingbird twists its wings to a very high angle of attack, which is necessary to generate and maintain a leading-edge vortex on the upstroke. The full-scale animation is here. (Image credit: J. Song et al.; via Wired; submitted by averagegrdy)

    Doing analysis is like this: you sit and you think and you stare and nothing happens, and then all of a sudden, you write a paragraph. And that’s a month of research right there.

    Both direct sum and tensor product are standard ways of putting together little Hilbert spaces to form big ones. They are used for different purposes. Suppose we have two physical systems…. Roughly speaking, if … a physical system’s … states are either of A OR of B, its Hilbert space will be [a] direct sum…. If we have a system whose states are states of A AND states of B, its Hilbert space will be [a] tensor product….
    MEASURE SPACE   disjoint union  Cartesian product
    HILBERT SPACE   direct sum      tensor product
