amazing

The depiction of the lips is incorrect. The lips should not pout and protrude into the cup of the mouthpiece. They should be vertically aligned as should be the teeth. However, you are quite correct in indicating that the sound is not created by buzzing. Unfortunately, most brass teachers steadfastly adhere to the buzzing principle.

Great performance, and lovely piece! Top it of with a good video and performance, this is very impressive and engaging

Hahahah this is awesome!

Beautiful.

Hi Mark, This video was an excellent intro for me to learn of a tool to visualize sound on a timeline. I am doing an art piece that demonstrates ordinary sound over about five minutes. Is there a transcription tool that might be printable? Or a certain graph paper? Appreiciate your knowledge and teaching skill. Maybe you can point me to another of your videos for developing my concept. Thanks you.

We never got to see what you were referring to when talking about the wavelengths in the tube. 🫣🫣🫣

We didn’t hear the playback … alas.

Although from a certain perspective it might be considered aesthetically unpleasing, it gets the job done in a very approachable manner. Are you redoing the whole series? I would want to give some advice, if you have a bar, and want people to come to it because you don't have any visitors, investing a large amount of money into it can be scary, because there is no guarantee you'll get it back. Then I want to present to you the fact that if you have something to offer which isn't being offered anywhere else, you have the advantage of having no competition, but competition can and will see what's going on and want a piece, if you just invest into making your bar (which is already offering an exclusive service) beautiful, you only invest big once, and after you'll never have to invest in making it beautiful again, so people will experience what you produced as something higher value just because the structure was made to last, and the beauty in that is that you will never have to invest in it again, so in the long term it's cheaper for you and those who are aesthetically minded will have to adapt to new found beauty and you'll get a larger and larger crowd just because you fully commited to your goal. Again, at first you'll feel exposed for your commitment to something very different, but eventually you'll find traction. Kind regards, Arthur!

Delightful introduction! I thought there was a nice balance of humour and explanations, and look forwards to seeing more in the series :)

OKaaay Not signing up for this class

And just think, Einstein said Time is like distance, he traveled periodically!

Fabulous! 26:24 ❤

Playing louder with more air without changing the speed of the air is the amateur flute player’s dilemma. ☺️☺️

12:15 Doesn’t multiplying the rate of change of velocity (-9.8m/s) by 2 (for 2 seconds) imply that the velocity downwards is steady; and not increasing (accelerating)? Shouldn’t it be squared?

I freaking appreciate this, very intuitive explanation, and very important, because rarely someone talks about this when explaining the physics of flute, I really appreciate it! This will help a lot with making my own 3D printed air instruments!

Hi. I'm confused as to why < psi_a | psi_b > does not just = 0.... are they not orthogonal?

I'm an incoming engineering freshman at UBCO, and I've been looking at your videos to get a head start. Just wanted to say that you seem like a really cool prof, and I wish I had you first year! (-:

😂

😊

Wow! You got a great thing going! 😊

Cool! 😂

Brilliant demonstration!

Are you dutch?

Spacetime is everything. Everything is spacetime.

Nice metaphor of how you were hot on the trail of a theory of quantum gravity, but ended up proving the simulation hypothesis instead! Great job, Dr. Van Raamsdonk! 😆

Hi Mark, I just came across your Physics of Music series while researching the specifics of how a glissotar works. Could you make a video about this instrument and the physics of it? I feel like it's an interesting instrument, but there seems to be a lot of misinformation about its invention, I think it would make a great video. Thanks!

Could you please tell how to obtain this graph? Is it a predefined availabke software or did you make the program yourself?

What reference do you recommend for this segment? Griffiths' description of H2+ ion is a bit lackluster.

In the world of electric guitars the mass of the strings at standard pitch is a correlation to ones manhood. Not the most scientific bunch :)

If you are ever interested in getting help from a video editor, i would be very honored to be it! Lots of potential!

How did you add the epsilon in the first place?

Thank you for doing this series! Just a small note, but as far as I can tell, this is the only CZcams video of this series that doesn't start with the series title "Physics of Music 68:", so at first I didn't realize it was part of the same series.

Dear. Prof. VanRaams , Thanks for this. Thank you for providing this. I never got the chance to go to MIT , to HARVARD, or BERKLEY. I can say though these videos allow me to learn new concepts. I have been following big questions like "What is Time" "What is our universe" "What is quantum mechanics and General relativity". So ten years ago I went on a rampage because I do not want to die not knowing what all this is? I followed Prof. LenSusk and he lead me to you. I started following your talks and have learn a tremendous amount.

This is the most detailed class about the acoustic of instruments. Obviously you need a previous knowledge about standing waves and the harmonic series, but you explained it in such an objective way that is almost impossible to don't understand. Thank you from Brazil ;D

Helium voice was hilarious 😂

Watching this 2 hours before my exam, thank you!

It never felt worse when a course ended. The legendary Mark Van Raamsdonk made it so much fun and easier for me to actually understand this. As a physics enthusiast and an engineering student, this video really gave me a motivational booster to do something like the huge interferometers. Thanks a lot for sharing the story!!!

Not the duck!!! RIP duck :(

NICE! Thx

@ 9:06 The physical argument behind this math explanation is that m can be the excited state. Because at t = 0 there isn't any excitation yet, the excited state m must be empty. Don't get lost in math! We just had a whole generation of physicists who got lost that way ;-)

@ 1:53 "Afterwards" the H-atom is only in one of its states, not in a superposition of states. The superposition principle is nothing but a theoretical tool, not a part of observed reality. @ 9:41 This suggests that between 'Start' and 'Finish' the atom can be in a different state. It can't. By the way, only the atom gets excited, not the electron. A common misconception. If, some day, we find that the electon has an internal structural, then it can probably be excited too. Nevertheless, a very nice introduction.

awesome stuff, this basically means that our ears do a fourier transformation!

this is perfect, real G indeed

Nice presentation thankss

The lips don’t close. There is ample proof of this when we review endoscopic video.
