A better description of resonance

A very intuitive example is a children's swing set. If you've ever been a child you'll know you can give yourself a tiny amount of speed by leaning forward or backward on the swing, and you can gain more speed by alternating with precise timing. If your timing is off (not resonant) you'll lose speed instead, but by making your small disturbances at the swing's resonant frequency you keep accumulating more and more energy.

Someone should make a book of 'Steve Mould Quotes'. E.g. -"I can smell percentages" -"It is a guitar, i'm just massive"

Thank you for repaired speakers. When you blown into a bottle, my speakers oscillated so strong, that something happened with connectors and I have stereo again, really.

Every time I watch you I’m astounded by how slowly you speak but how much clear, useful info you’re giving in every sentence. Apart from the awesome info you give, I’m paying almost more attention to how good you are and conveying the knowledge so I can get better myself.

Small thing: The perceived frequency is actually the loudest resonant frequency - this just so happens to almost always be the lowest one, but it isn't always. In a clarinet (I think?) it is possible to create sounds where the loudest resonant frequency is not the lowest.

When I was much younger I used to do a lot of cave exploring. One thing I always enjoyed doing was finding the resonant frequency of the cave passage I was in. It was usually a low wet long crawlway or canyon. It was normally a fairly low frequency, like when you clear your throat. When I would find it, it would greatly amplify and rumble down the passageway. Lots of fun, but sometimes it unnerved the people I was with.

I always liked the statement my physics prof told me in my honours year. Resonance is the frequency at which maximal energy transfer occurs from the extremal driving force into the system.

I am 70 and have been playing music since I was 3. Now, I play touch/velocity-sensitive wavestation keyboards...and I found this presentation utterly fascinating.

"Yes, this is a guitar, I'm just massive". I love you Steve

I remember my High School chemistry teacher did the Rubens Tube! It's so cool :D

i always really hated my math and science classes in high school--it never felt like i understood what was going on, which made me very anxious, which only made learning more difficult. not only does this channel make science concepts intuitive and easy to learn, but i also find myself arrested by the loveliness of the language of science. somehow steve's very plainspoken explanations feel beautifully and comfortingly poetic. im in grad school now for something non-STEM but watching these videos makes me forget my science-related fear and feel like an excited kid again in the best way. i feel intellectually nurtured and inspired :) thank you, steve!!!!!

That tube is wonderful. I’ve never heard of it and it is the coolest visualization for standing waves I could ever imagine. Thank you sir.

Seriously great explanations and super well presented! I saw one of your TED talks where you said you were more like the poor uncle of a teacher.. I see you more as the guy we come to when the teachers and resources provided to us lack the passion and ability to describe in a way we can understand... the guy behind the screen, building the passion that teachers take credit for. The guy that blows white noise into a students head and causes the passion for science and the world around them, to become the antinode of their lives. You rock Mr Mould!

"It is a guitar, actually. I'm just massive."

Thank you Steve. The best video I have ever seen on Youtube. Your way of explanation is not only far superior but also highly logical which helps the propagation of knowledge through many man-made barriers.

I have not seen a better explanation of resonance than this. This is amazing. This kind of experimental equipment is found in very few labs.

Your description of understanding entropy was absolutely amazing. Now I know much more about entropy than before and that is thanks to you! I wish I had a teacher like you in the schools I went.

This needs to be a larger series and more people should be watching it.

I am amazed by the clarity of thought and explanation. We need more teachers like these

Our physics teacher showed us this in class last year! It was a beautiful sight with all the classroom lights switched off
