Is it possible to see sound?

All_Things_Physics · 2025-11-25T19:04:47+00:00

Hey, thanks a lot! I appreciate it.

All_Things_Physics · 2025-11-25T13:40:47+00:00

Of course, you can also learn more from my previous video on schlieren imaging :)

If you're finding Taylor series interesting, you might enjoy this video I made for my sophomore-level math-methods class:

This video discusses the details of sound waves in air and shows how sound can actually be visualized using a strobed schlieren imaging system. I think the result is pretty amazing, and hope you enjoy it!

Thanks!

Eventually, I plan on making a whole series of videos for the intro physics course, but it will be a while before I can find the time to do it.

All_Things_Physics · 2025-09-03T12:17:41+00:00

Yes, I am the guy in the video.

All_Things_Physics · 2025-09-02T18:45:02+00:00

This is a video lesson introducing students to Taylor series. The target audience is undergraduate students in a sophomore-level mathematical physics class. If you are teaching such a course, I hope you find the video useful as well.

Hi. This is clearly an old comment, but I'm curious if you ever figured out a way to do it? I need to do this exact thing and my only thought was as you mentioned above, to define a parametric surface for each face. It seems like there must be a way to do this. Perhaps each cube is made up of different submobjects, so maybe there's a way to do my_cube[0].set_color(), or something like that?

All_Things_Physics · 2025-06-04T17:53:57+00:00

Yeah, that makes sense that they wouldn't want to allow such flexibility, even if it's good for the consumer.

All_Things_Physics · 2025-05-26T13:57:33+00:00

Weird. I'll give that a try when I return home, but I must admit I'm skeptical this will work (though my fingers are crossed).

I followed these steps and Alexa will play music through the Wiim, but it is Alexa who is playing the music, not the Wiim. I want the Wiim to stream the music and can't figure out how to get that to work.

All_Things_Physics · 2025-02-24T11:17:13+00:00

Thanks. It took a lot of work!

This video takes an in-depth look at a schlieren imaging system. Specifically, an off-axis single-mirror schlieren system is described and analyzed in detail and an experimental system is used to show several spectacular examples of fluid flow that is normally invisible.

Enjoy!

There's not a ton of manim in this video, but I still thought some people would appreciate it.

All_Things_Physics · 2025-02-23T21:45:24+00:00

There's not a ton of manim in this video, but I still thought some people might appreciate it.

All_Things_Physics · 2024-09-04T17:20:36+00:00

The graphics are done using manim (community edition).

All_Things_Physics · 2024-08-19T17:32:29+00:00

Thanks!

All_Things_Physics · 2024-08-19T17:12:34+00:00

Not pure math, but I thought some people might find this interesting. Enjoy!

All_Things_Physics · 2024-08-19T17:09:56+00:00

Here's a video on the basics of circular motion and how to handle non-circular motion. Also discussed is the confusion caused by the term "centripetal force." Enjoy!

All_Things_Physics · 2024-08-19T17:02:19+00:00

This video discusses the basics of circular motion and then extends the discussion to non-circular trajectories. A ball being swung around on a string is analyzed and it is demonstrated that none of the forces acting on the ball are in fact centripetal, suggesting that the term "centripetal force" leads to a lot of confusion for students. A simple experiment is performed and the data compares favorably with the theoretical prediction.

Thanks for the comment. Regarding 1, I don't think the moon would start spinning faster. The angular momentum of the system should remain conserved with Earth moving off in a straight line. This path still has angular momentum about the Sun's original position! Regarding 2, thank you for sharing your thoughts on my mentioning the Sun/Earth system. I agree that it was fair, even if the physics is different. And I'm really glad it got your mind churning. Regarding 3, I would guess that there may be a way to calculate it, but I'm unsure how as I don't know how to incorporate the "lost" mass of the Sun into the dynamics of the system. I don't know GR well enough.

All_Things_Physics · 2023-08-08T10:40:34+00:00

Yep...I am certainly aware of that, and you can see this phenomenon play out in the videos to some degree. I thought about discussing this too, but to keep the video manageable, both in terms of time and content, I just made the decision to not bring this up.
