Reduction in Physics: Your turn

  1. Apr 24, 2004 #1
    Physicists are often taught to refine a complicated situation into basic laws and parameters. Here you are to think of a real-world situation and reduce it in terms of progressively simpler models while retaining fundamental physics. Try to improve on each other's examples, or introduce an example of your own. E. g.,

    1. The trajectory of a thrown ball.

    2. The trajectory of a thrown ball without friction.

    3. The trajectory of a thrown ball orbiting the Earth without friction.

    4. The trajectory of a thrown ball, collapsed to a singularity, orbiting the Earth, also collapsed to a singularity, without friction.

    5. The trajectory of a thrown ball, collapsed to a singularity, orbiting the Earth, also collapsed to a singularity, without friction and in a universe void of any other matter.

    6. The trajectory of a thrown ball, collapsed to a singularity, orbiting the Earth, also collapsed to a singularity, without friction and in a spherical universe void of any other matter.

    7. The trajectory of a thrown ball, collapsed to a singularity, orbiting the Earth, also collapsed to a singularity, without friction and in a spherical universe void of any other matter and quantum effects.

    8. The trajectory of a thrown ball, collapsed to a singularity, orbiting the Earth, also collapsed to a singularity - both now coalesced - without friction and in a spherical universe void of any other matter and quantum effects.
