If I was a spherical human in a perfect vacuum, this is the kind of stuff I'd spend my time on all day.
-
"Just shy of infinite" is a very funny phrase.
-
I feel like this channel is the epitome of the idea that anything in the world can be interesting if you look at it from the correct angle!
-
I love this channel, because it doesn't assume the audience knows nothing like most science channels, but it still explains everything clearly in case you don't.
-
For a while you've been making videos that are honestly some of my favorite on the entirity of youtube! They're niche but interesting and engaging which I find so impressive. They're also sneakily educational which is wonderful. Thank you for the incredible works.
-
Great video! Fun fact, the magnets don't bounce infinitely many times due to the air's viscosity... There is a cutoff for a critical Stokes number (and another characteristic elastic number) for which particles approach one another without rebounding.
-
Once again you've managed to create an absolutely captivating video about a topic that most people never really think about. I love the pacing of your videos and how you manage to connect two seemingly unrelated concepts in unexpected ways.
-
I love your video topics. They are simultaneously so disconnected, unpredictable and somehow still carry similar „vibes“. I hope you will be able (want to) continue to explore such unique topics.
-
My greatest accomplishment in life will be when I can understand everything being said in physics videos like these. I understood about half of the video so I’m getting closer.
-
As a kid I once accidentally found two oddly-shaped magnetic rocks while goofing around in my neighbors’ backyard, and I loved them, and they made a similar sound. Sadly I’ve since lost them but I have never forgotten them.

Congratulations on the 100k!
-
Something about this video hit different. They usually feel like you are here to teach me something neat, but this time we were on an adventure to calculate the physics of a random part of life! It was so much more engaging!
-
As an engineering student my first thought after realizing that the force is inversly proportional to the inverse of the distance, was "Just approximate with a linear function", so when you said you're gonna assume constant force it just got better.

What is the sound of two buzzing magnets? -- ancient bird proverb
-
I absolutely love your videos because they're this wonderful combination of niche topics with eloquent explanations and amazing visualizations! Nothing else on YouTube can come close to these! Thank you!
-
It would be interesting to use those frequency curves to synthesize an audio clip, and see if it sounds like the real magnets.
-
rarely do I watch a math video where I feel the math as much as I hear it. This just FEELS right as you go through explaining it.
-
Just discovered your channel: love it. You elaborate with simple but clever and effectice animations, and you explain the math behind it without dumbing stuff down too much but pacing it enough that its entertaining even to people who aren't here the check or recreate your work.
-
As many said, your videos are amazing. One thing I have to mention is about your video on music. The part where you explained why and how certain harmonies sound good for us has a special meaning to me. I experienced this before watching your video, while messing around with sound. Your explanation was kind of a miracle to me.

I used to have a pair of those magnets as a kid that i haven't thought about in almost 2 decades. Amazing video as always, and thanks for the blast of nostalgia!
