  • Instead of being “pointlike,” they are modeled by filaments of energy so tiny that there is no known way to observe them or even to prove they are real.

  • Next, identify pairs of canonical conjugate variables, such as coordinates and momenta for pointlike particles (Ch. 21.2), the angular variables φ and cosθ for spins, or whatever.

  • See p. 496, where this procedure is implemented for the case of a nonrelativistic pointlike particle.

    Are Changes Brewing and How Does the Mind Fit In?

  • We pretend that masses and electric charges are pointlike, which simplifies the calculation — we can specify the location of the object by saying it lies at point X.

  • (Section 13), all fundamental particles can be considered to be excitations of underlying non-pointlike entities in a multi-dimensional space.

  • Moreover, if our lens is not a massless pointlike event, it will also have its own differences in accelerations at the surface that will influence its interactions with infalling particles from the direction of Hyperion.

  • We would see quite a few pointlike and smearlike objects which would

    The Arrow of Time in Scientific American

  • Apparently the person on the street is sufficiently caught up with current thinking in high-energy physics to know that string theory — the idea that the ultimate building blocks of nature are quantized loops of string, not pointlike elementary particles — is our leading candidate for a theory that would, indeed, “explain everything.”

  • To be clear when I say not pointlike, I mean at least 1 dimensional or greater.
