This is the third in a sequence of 3 videos I made about kinetic energy and its relationship to confinement, etc. It is posted first because originally the other two are delayed due to upload problems. Actually, it might be fine to start with this one. The first two are pretty focused on calculating expectation values, whereas this one is more focused on considering and discussing the nature of momentum, KE and confinement and how they may be related. In it we examine the nature of a electron state (mixed state) in which the degree of confinement varies with time. The comment section below would be a great place for any questions or thoughts you have about this important subject. Sometimes I am not sure if many people actually view these videos, and whether or not I should continue to make more. So if you do I would appreciate knowing that. Just even a short comment or a vote in the poll would be appreciated.
PS. Here is the 1st video from the sequence I made on Tuesday.
The 2nd video from the sequence about momentum, KE and confinement (part2) is embedded below.
I recommend watching the 1st 10 minutes or so of this video, and then perhaps skipping ahead to part 3. After about the 10 minute mark this one gets into a pretty tedious calculation. Part 3, on the other hand, (which is up above in this post) focuses more on relationships and meaning and less on detailed calculation. Part 3 may be more interesting.
Agreed, I have found the videos to be very helpful because of how concise they are. Thanks for making them!
ReplyDeleteprofessor I think if you click on the color wheel you can use any colors that aren't in boxes on the palate. there is a black dot that you can click and drag to whichever color you want to use.
ReplyDeleteYou also made an error calculating the (negative) second derivative. You only distributed the negative to the first term but the other two terms with $x^2$ and $x^4$ did not have a sign change.
Watched the video, helps with reviewing the importing topics in class
ReplyDeleteReally good videos, doing the calculations along with the video is great practice
ReplyDeleteDefinitely helpful, great to work along with!
ReplyDeleteYou're not late, Jezus53. I appreciate the feedback! any from everyone else too!
ReplyDeletei watched 1&3 so far. They were helpful and interesting. Thanks!
ReplyDeletereally late but i watched them and they help a lot!!!
ReplyDeleteI'm glad. Hopefully they will help you for the midterm.
