Magic Magnetic Balls Defy Physics #SoME3
When rotating two tubes with ball magnets inside something very counterintuitive happens: The balls roll up against gravity. This video tries to explain the physical mechanism behind this phenomenon.

Difference between a Saxophone and a Clarinet #SoME2
Просмотров 52 тыс.2 года назад
Saxophones and Clarinets have many things in common, but the sound of these instruments is different. But what is actually the difference between a Saxophone and a Clarinet? It's not the material, not the curviness and it has noting to do with the placements of the holes. 0:00 - Introduction 02:51 - The Flute / Open-Open Pipe 05:13 - Closed-Open Pipe 06:16 - Comparison 07:57 - Solution 10:54 - ...

    First glaring mistake: comparing plastic clarinets to saxophones. While plastic clarinets are good, plastic saxophones that can make any notable sound do not exist. Also, the Tarogato is NOT A WOODEN SAXOPHONE. It’s a completely different instrument.

    So why does a saxophone sound nothing like a flute?

    • @pascal_pauli
      @pascal_pauli 9 месяцев назад

      The saxophone doesn't sound like a flute because the amplitudes of different harmonics are different for the two instruments. The flute does not have so many strong overtones and is somewhat comparable to a sine wave. The saxophone has more overtones with different amplitudes. I guess the main reason is the sound creation through the different mouthpieces.

    I like your video, however, I want to point out a caveat about the second law. It is commonly misunderstood that entropy means the same thing as disorder. You definitely could get the configuration of the LOL pattern regardless of which direction time is going. The second law does not say that order decreases over time. It is simply a statistical statement which applies in both time directions, where if you increase the volume of possible states for a set number of particles the number of possibilities increases. Therefore the entropy of the universe should actually stay the same because the universe is not actually becoming more volume us in space-time because the space-time itself is stretching not appending more.

    You pulled that apart well. I have over 20 years of screaming that right-hand rules are mnemonic devices and do not belong in explanations of cause. Look at the real CAUSE of the gyroscopic effect. Angular momentum is a math analogy that indirectly gets the right answer but leads you away from the cause. Spin velocity and tilt velocity are perpendicular vectors that will not affect each other. The gyroscopic effect is a collection of several effects, and one in particular, the causal accelerations, are something you've never seen. My video was a hasty zoom meeting presentation, so it's not about production quality. ruclips.net/video/Sip_9ew2RjA/видео.html

    Can you lube the tubes and see how that changes the speed they climb the tube by lowering friction

    • @pascal_pauli
      @pascal_pauli 9 месяцев назад

      That should work. We tried the opposite way by roughening the surface of the tubes with sandpaper. If roughened, the balls were even able to push a small weight. This was not possible with the previous smooth tubes. But I haven't tested the use of lube but I guess it should do the same.

    I'm curious how this translates to the human voice? 1) what type of pipe are we like, if any? We are able to produce all the harmonics, is that because we're like a cone? 2) are the harmonics we produce caused via addition of sines converging (like these instruments) or from the pattern of the vocal fold "wave"? In more technical words, are human harmonics caused by the pattern of the air pressure in TIME DOMAIN, or by a convergence of perfect sine waves in the FREQUENCY DOMAIN?

  • @kevincrotty826
    @kevincrotty826 Год назад

    So a saxophone has a closed mouthpiece, so it should have one open end (like a clarinet), but since it conically expands it effectively has two open ends (like a flute). The gross generalization I take from this is that conically expanding bore adds one the the number of openings. Obviously, the next question is: what does a standing wave in a tube with three open ends sound like? What is the sound of the flutophone, aka flaulto sax? Looks like the experiment has already been performed, and the results are not promising: ruclips.net/video/EN9BBYIp0OM/видео.html
