      Sir, you have summarized so nicely, the heave of sigh at the end of the lecture was so appropriate. Jokes apart, I don't think anybody has explained this weird stuff so artistically, I am amazed at your effort of making us to understand. No wonder you have chosen the name of channel as "Love of Physics" . Please post many more videos.

  • @ajaykulkarni576
    @ajaykulkarni576 9 หลายเดือนก่อน

    Great Work , this is very well done. Is it possible to take some real time use of this? Like how somebody uses this to find average postion and use that average position for a real application.

    • @MikeRicos
      @MikeRicos หลายเดือนก่อน

      My favorite example is a spectrum analyzer for audio. The longer you capture, the better you can pinpoint low-frequency content. If you want to catch really slow frequencies, you have to wait and collect more samples.
      This means there's a tradeoff-you're either focusing on when something happened (time) or what frequencies were present. It’s kind of like position and momentum being conjugate variables. The more you know about one, the less you know about the other.
      When I first realized that measurement in this context *requires* an integral (over time), it finally clicked for me.

      represents the velocity of the position_average of the system with time. It's more useful to us as it gives us an idea of how the wavepacket evolves with time.

    Instead of doing derivations which are already there in any standard textbook, i think you can better solve problems (for example, problems from JJ Sakrai). Also i didn't see Linear Vector Spaces in the playlist.

    • @Anna-sd4zl
      @Anna-sd4zl 3 หลายเดือนก่อน

      It's because this is a beginner level quantum mechanics no need for introducing vector spaces if we go by introducing vector spaces students need to know some prior functional analysis which isn't necessary for introductory quantum mechanics

    "The wavefunction contains information but does not have any physical significance".--Hmmm. I see the point you are making there, but not convinced it is true. This is kind of like saying the equation of motion in classical mechanics does not have any physical significance since classical mechanics is a special case of the more general quantum approach.

    • @FortheLoveofPhysics
      @FortheLoveofPhysics  9 หลายเดือนก่อน +2

      By that I mean, The wavefunction is not a physical quantity, but contains information about the average of various physical quantities like position, momentum etc (and later we will see, it also contains information about eigenvalues etc).
      In Classical mechanics however, the equations of motion reveal to us - solutions which are physical quantities, like position, momentum, energy etc
