The low poly style make me focus easier on informations. Greatly prepared! This example with metal rod between earth and moon - I never thought about it from this perspective, very nice and I would love to see more. Maybe how the sound is propagates in space and interacting with obstacles? And the fact you are using the Blender 3D makes it even more interesting. Thank you.
O My God. This video was fabulous. This is how concepts should be taught at school. You are doing an amazing job at presenting your concepts. Secondly, correct me if Im wrong, but the distance the steel rod was pushed was lesser on the moon because some energy was lost on the way to the moon due to heat etc.
You're correct! Definitely, losses due to heat are one thing that would reduce the movement on the moon side. The other main one is compression and expansion.
Science is modern magic. It’s stuff like this that make life interesting to me. It’s also amazing chance that we happen to have ears to catch these sound waves. Looks like I’ve got to watch the ear video now
I was supposing that's how sound worked by using thought experiments. It seems my intuition was correct, however I did learn some things I had not thought of before. Thank you. Just wanted to make sure I was correct so I came to this video.
Wow unbelievable, way of concept clarification is stunning. This is how schools should actually teach but what they do is they make us a book worm who mugs up everything overnight and take examinations.
So I guess what I'm about to ask is part of the suspended factors, but I'm still curious: if sound doesn't travel indefinitely, because somewhere along the line the energy get's lost I guess, would the steel bar also not propagate the entire movement of pushing it upwards through to the moon? Would it bounce back or something?
So what would prevent the motion from reaching the moon would be the compression/elongation of the bar, which is represented by hooke's law en.wikipedia.org/wiki/Hooke's_law. Whenever any object gets a force applied to it- either pushing, pulling, or any force- some dimension of the object gets distorted. With small objects or small forces, it's a small distortion, but with an extra long bar, the 1 meter push or pull would be the amount the bar was distorted (elongated or contracted), and because the bar just changed its size the moon end wouldn't see any movement. However, if the motion were to reach the moon, the force would bounce back.
Thanks for watching them! Signal processing will definitely be a video one day, but first I gotta lay some more groundwork videos. One of the upcoming ones will be wifi, which is a good start for signals.
This nice video has reminded me the passage below; Id like to share this different point of view of truth: "If, for example, there is one point on a piece of white paper and two or three other points are jumbled around with it and then someone who already has numerous jobs tries to distinguish them, he will be confused; and if many burdens are loaded on a small creature, it will be crushed; and if numerous words issue from one tongue and enter one ear altogether at the same time, their order will be broken and they will be a muddle. Despite this being the case, I saw with complete certainty that with the key and compass of HE, although thousands of different points, letters and words had been put in each molecule -and even in each particle- of the element air, through which I journeyed in my mind, NEITHER THEY BECOME MİXED UP NOR DİD THEY SPOİL THEİR ORDER; and although they performed a great many different duties, these were carried out without being confused in any way; and although very heavy loads were laid on each molecule and particle, they bore them in order without lagging or displaying any weakness at all. And I saw that thousands of different words of all different sorts enter and issue with perfect order from what is in effect those MİNUTE EARS AND TONGUES without being mixed up and spoilt in any way, they enter those minute ears and issue from those tiny tongues, and by performing these extraordinary duties, each particle and each molecule declares through the enraptured tongue of its being and its perfect freedom, and through the testimony and tongue of the above truth: THERE IS NO GOD BUT HE, and: SAY, HE IS GOD, THE ONE, and travels among air-clashing waves like storms and lightning and thunder without in any way spoiling their order or confusing their duties. One duty is not an obstacle to another duty. I observed this and was utterly certain. That is to say, either every particle and piece of the air has to possess infinite wisdom, knowledge, will, and power, and the qualities for being absolutely dominant over all the other particles so that it can be the means of those functions being carried out, which is absurd and impossible to the number of particles, and no devil even could imagine it, or else, and it is self-evident to the degree of 'knowledge of certainty,' 'vision of certainty,' and 'absolute certainty' that the page of the air functions through the boundless, infinite knowledge and wisdom of the All-Glorious One, and is the changing page for the pen of Divine Power and Determining, and like a signboard for writing and erasing, known as a Tablet of Appearance and Dissolution, which has the function of the Preserved Tablet in the world of transformation and change. Thus, just as the element of air demonstrates the above-mentioned wonders and manifestation of Divine unity in only the duty of transmitting sound and shows the impossibilities of misguidance, so does it perform other important duties with order and without confusing them, such as transmitting subtle forces and energy, like electricity, light, and the forces of attraction and repulsion. At the same time as conveying these, with perfect order, it carries out duties essential for the lives of plants and animals, such as respiration and pollination. It proves in decisive fashion that it is a place of maximum manifestation of the Divine will and command..." Words - 174, by Said Nursi
That was an excellent, clear explanation! I now know the answer to the Q that led me here but wasn't directly discussed in the vid: Why does the shockwave from an atomic bomb travel at the speed of sound?
What is also really interesting is how wind affects the behaviour of sound waves. For instance sound heading down wind is curved downwards and sound heading up wind is curved upwards. I realized this after noticing where I live the sound from the ocean is able to head over about 1km of thick high trees and I can hear it almost crystal clear as if the beach is right next to me. I realized the sound couldn't possibly be getting through the trees so must have to be travelling over them and then curving down to where I am. When i looked into it I realized that this was actually scientifically accurate as to how wind affects the curve of the sound waves.
Started off as wtf is a steel rod doing here and almost left , but since I’ll look for different examples and materials as teaching aids , I continued to see what you were on about and the connecting of dots just hit me , well don on the explanation, the animation awesome too !
Glad you stuck around! I'm glad the dots connected by the end. It's a complicated topic that I feel a lot of students misunderstand- especially when they think a travelling sound wave moves across a room as a physical object moving in a sinusoidal motion.
I live next to a busy road and its seriously annoying. It makes more sense to know that each and every air particle between me and those vehicles is being violently dislodged and banging into its neighbour all the way into my ears!!! Its no wonder it 'feels' like I'm being attacked!
Those who don't understand why 1m didn't travelled instantly, its 1 m respect to 384000000 m... And thats the level of movement, springiness of medium which constitutes sound waves
It’d be crazy to see the math behind figuring out how quickly the force moves throughout the rod while also taking the varying temperatures into account
This is an amazing video, just like all the videos you make. I have a question. You say in this video - ………. and branches from this episode are what are sound waves, what are the different types of waves how do your ears perceive sound, what are frequency and loudness, if the sound is the movement of air particles, then what is wind isn’t that also the movement of air particles…………..? Where can I find these branches? Are these episodes still in the making?
What if i change angle of rod on earth? If rod is tilted by 45 degree on earth, will it take so much time to reach moon? If yes then how will the shape of rod hold up?! , it will be bent and will not be a straight rod. I understand everything is assumed, but I'm just curious.
Well, the angle change will definitely change the required distance so it will change the time. If the rod were able to bend, then it would be able to compress and expand. So the initial push from the earth would be 'negated' by compression and expansion.
atleast it isnt like my module here because, i would love to learn in a very advance version than just seeing teachers explain, i would love to hear this
This is an amazing video, just like all the videos you make. I have a question for you related to some of them. You say in this video - ………. and branches from this episode are what are sound waves, what are the different types of waves how do your ears perceive sound, what are frequency and loudness, if the sound is the movement of air particles, then what is wind isn’t that also the movement of air particles…………..? Where can I find these branches? How could I have access to them?
thanks a ton for the excellent video and deep explanation. I have several doubts. 1.I see that the way sound travels thru metal bar (by pushing atoms, which push subsequent atoms, so the disturbance travels very fast, though the atoms themselves do not move much) is very similar to how electricity travels thru a metal wire (by pushing electrons at one end, which push subsequent electrons, so the effect travels at extremely high speed, though electrons do not themselves move much). Why then, the former is at speed of sound ~5000m/s, while the later is speed of light ~300 million m/s?? 2. Sound wave needs a frequency, but Where does the concept of frequency fit in this experiment? Say i have a metal bar and i hit one end of the metal...then i am pushing atoms at that end and that push travels from atom to atom till the other end, so an ear/receiver attached to the other end hears a sound. But here there was no frequency, just a single hit. How come there's still a sound wave??? 3. "A metal bar. Force applied at one end, but there is push and pull alternately at some frequency". I think this is analogue of a sound wave or pressure wave of some frequency travelling thru a metal, which is when the metals oscillate about its position at same frequency. Is it? What about when there is no frequency of hit, i.e. 'single hit' case- Do the atoms return back to their position after being pushed to some distance (if so, at what frequency)?
4. How sound travels from metal to air? 5. Why electron wave is transverse (though the electrons are moving just like in this video, i.e. longitudinal, i.r. along the direction of wave propagation), whereas sound wave is longitudinal? 6. Electron wave(i mean, electromagnetic wave) exits from metal wire to air around itand we use antenna principle to enhance it. What about sound wave- how does it exit from metal/wood to air and what 'antenna' can aid that propagation?
If I use a 1 meter stethoscope then someone whispers on the chest-piece in some desibel as low as a whisper can be heard in 10 cm through the air, which one of these ways, a direct whisper in 10 cm through the air or the whisper through the stethoscope will sound or voice travel faster? Thanks anyway.

The way you help understanding with using visuals is one step above the learning material i have witnessed so far. Thank you for your education, it's a blessing.
Big deal, the higher you go the slower sound travels. You go high enough, and you could break the sound barrier at 1MPH.

Can there be a “drag”? Sinds you do it over such a long distance. And wave looks like energy, can’t you lose that energy or part of it along the way?
