Super cool fun fact: when the massive Tonga eruption happened last year or maybe the year before, i don't remember, the University of Idaho was doing some research recording how sound was affected by snowfall or something, and when they analyzed the data, they saw some irregularities in their soundwaves. When they amplified the audio and played it back, they realized they had recorded the eruption from the other side of the world, not once, not twice, but three times over. The sound reached them first by going East, then they picked up the same sound of the same eruption, this time heading west, and the third spike in the audio was actually the first one again, circling the earth and being picked up again minutes later.

I would've thought that another problem with Marconi's idea is that sound waves can cancel each other out, so the sound field, if you will, would gradually lose information.

@@ATinyWaffle Well, no actually; at least according to the Standard Model of Quantum Mechanics, all interactions between particles conserve information, so it is theoretically possible to reverse engineer every physical action just from a detailed model of the present. Marconi just didn't account for how energy can change state, so this wouldn't apply to sound in isolation.
You would only “loose information” if a copy or echo of that sound was 180° out of phase with the original. It’s that principle that noise cancelling headphones work from.
@@gaz0463 That would give you complete cancellation, but you can still have partial cancellation without a copy of the sound; it's all just pressure waves, at the end of the day.
Not to nitpick, but since qi as a show is founded on pedantic distinctions, I feel we have to point something out. When she asks if you can hear sound from the past, the unequivocal answer is absolutely yes. And the reason is because it takes time for sound to travel. That means that when a sound is made and when you hear it, a small amount of time has elapsed. The amount of time is proportional to the distance the sound travels. But all sound that you hear is from some unit of time in the past unless the sound you're hearing is made by your ears themselves. Much like a point Stephen Frye made once about seeing things in the past and how it takes time for light to travel as it is reflected from a mirror that you look into. So I was really hoping when she asked that question someone would say yes you can hear sounds from the past and then she would have to give it to them.
It's certainly not possible to hear sounds from the future - ie sounds that have yet to be created. The 'present' is so fleeting, given the nature of sound transmission it's not possible to hear sounds from the present. So that only leaves 'sounds from the past'.
You are absolutely correct. Every sound is from the past. The answer "sound travels forward" is also correct. It travels forward in both distance and time. If you were standing 332 M from a sound source, it would take one second before you would hear it.
Although to say it travels forwards is not strictly true. Light photons travel in the direction of emission, sound is far more like a ripple in a pond. It's dissipation in all directions means that the latitudinal pulsating energy has many more places to go and thus be lost in. This factor is why the concept of rewinding a space to reconstitute its vibrations to hear a long finished conversation simply cannot work in practice, there are simply too many factors with absorption and reflection of surrounding surfaces.
I'd imagine that sound that doesn't cancel out outright is essentially energy in the form of movement of its medium (usually air for humans). And as it is movement it will eventually convert to heat and dissipate into the body of whatever it is in.
There's got to be a cool sci-fi story in there somewhere what with the whole "inventing a machine sensitive enough to detect ancient sound." It doesn't need to be accurate to be interesting. Hmmm... might write one myself lol
I read a sci-fi short story years ago where they used a needle (or possibly a laser) to read the spiral grooves etched into an ancient ceramic pot that was turned on a potter's wheel; the sounds of horses hooves etc. Can't remember where I read it though, some sci-fi compilation.

He invented it successfully. But for some odd reason all he could hear was "Never gonna give you up Never gonna let you down Never gonna run around and desert you Never gonna make you cry Never gonna say goodbye Never gonna tell a lie and hurt you"
Technically, the science teacher lady was right. Sound does travel forward.... In time. It can't travel back in time. And it exists from a point in time, and decays over time, thus, it travels forward in time.
@dielaughing73 Well you can. Next time there's a thunderstorm do that thing where you count the seconds between seeing the lightning and hearing the thunder. We hear sounds from the past all the time. But normally we're talking *seconds* , not years and certainly not two millenia to listen in on Jesus. If you throw a pebble in a pond you can see the rings on the water spreading outward only up to a point, and it doesn't just keep going on forever. The waves will be absorbed and equilibrium restored. It's probably better that way because if we *could* listen far back in time, I'd argue that there have been a lot more farts than sermons on the mount, so you'd be listening a *lot* more to the former than the latter.
The only thing that bothered me about this is we didn't make the distinction between sound and radio waves. Radio waves are a form of light that travel (dependent on the medium it's travelling through) at the speed of light. Sound is nothing but a vibration and cannot travel faster than the speed of sound (dependent on the medium it's travelling through). If Jesus made the sermon via radio and we could travel faster than the speed of light, we could potentially catch up to the original transmission or the transmission could get reflected back to us. As all Jesus did was make some vibrations, these have dissipated long ago and could not possibly be retrieved as they do not exist anymore.
What bothers me is the fact that a so-called factual informative show like this would credit Marconi as the inventor of the radio. And I'm not saying that Marconi wasn't brilliant, but in actuality it was Nikolai Tesla that was the pioneer of radio.🤦♂️
That's an invitation to a big philosophical discussion about the definition of sound though. By the time it can loop around the earth it's usually referred to as a shockwave. I don't think a single tone can travel the earth and still be recognized with accuracy.
It should be noted that there are multiple factors that prevent ancient sounds from still being detectable. One was mentioned about dissipation over larger and larger volumes of air. Eventually the vibration of atoms based on temperature is of greater magnitude than the sound. A second is wave interference. Some waves combine to make a single stronger wave while others cancel each other out. In most situations this will end up being partial or intermittent disruption in the same way radio interference produces static in radio transmissions.
There are reflections off the boundaries between air layers with different ionizations. Just as with light incident on a boundary between any two media with dissimilar indices of refraction, both reflection and refraction take place.

(Maybe you have to have watched the episode where they're agonising about how to say 'Newfoundland' 'tho to really relish it)?
Sound is carried by vibration of molecules in the atmosphere and only a limited amount of energy can be transferred to the next molecule. If his theory was correct, then every single molecule in Earth's atmosphere would contain the vibrations from every single sound that has ever been made.
Pronunciation tip: it's neither 'NEWfoundland' nor 'NewFOUNDland'; we here pronounce it with stresses on both the first and last syllables, 'NEWfoundLAND' (like 'understand').
Sound gets weaker and eventually the sound wave loses information as the wave itself collapses to more basic (flatter) format. It stays around for some time but you cannot decode sound that has been around for too long. The only thing I am not sure about as if the wave length itself (frequency) also changes.
Does anybody else find it funny that they decided to cut sandi''s end of video bumper and make it so she's on a laptop that gets closed before she can read the book and say "well, come on, pick something!" I mean, it was kind of rude. lol.
She was my science teacher during GCSE for like half a year. I told her I'd seen her on tv and at first she denied it. Then she came by a few minutes later and asked what I'd seen her on.
They joke about the pronunciation of Newfoundland but come on! Sandi moments later says "new-found land". Which is like the grating sound of Americans over-pronouncing (the English, not the Alabama) "Birmingham". It's "new'fund'lund". The only regional difference should be American "noo" vs British "nyoo".
While the sound going around the earth as Alan said is not quite in keeping with reality, there have been instances where huge explosions have propagated soundwaves around the earth several times. The rotation of the earth had little to do with those feats, however. What he is implying is a bit like if you find out where the speed of earth rotation works out to be equal to the speed of sound in air. You could make the big noise in the counterrotational direction and it would kind of hover in place (ignoring that the earth both rotates AND moves around the sun which orbits the galaxy which hurtles around in intergalactic space) while the sound source speeds away by standing firmly on the ground and eventually the sound source would rotate back to the origin where the sound just arrives. 🤔 Hmmm 🤔 It may not be as insane as I first thought. I mean, there are a huge amount of variables that makes it not feasable as an experiment. But if we can use the mindset of mathematicians who calculate spherical cows... There might just be something to this conundrum.
I was going to say something like this, good description. I assume your thought experiment at the end is a joke, however I want to explore it. Remember the volcano in the South Pacific (I can’t remember exact name location) but it became the biggest explosion ever recorded from space. That blast could only be heard 7,500 miles away. Or roughly a third of the circumference of the earth. Now imaging making a speaker large enough and with enough power to amplify a voice to go further. Plus since noise is Omnidirectional and pressure waves follow the noise you would destroy everything within miles of the source in an instant. So unless you are Dr. Evil, I don’t think this will ever happen.
And you're wrong too! I love it when someone tries to be a smartypants and blows it! It's not "new fund LAND" it's "new f'n l'nd" - you know... like f'o'c'sle. That middle D is silent and the proper pronunciation is njuːfənˈlænd note the schwa and lack of D. You're welcome.

0:48 I know it's nitpick-y but that image of Jesus isn't Jesus because it's based on one of two paintings, one by michealangelo and one by Leonardo da vinci, both based on the (male) lover of the artist. One of these men that the modern image of Jesus is based on was the son of the Pope, and he ordered all images of a bronze-skinned Jesus to be removed and his son's image to be put in it's place. So, basically, the modern image of Jesus is based on two queer men and the real Jesus was middle Eastern
All sound that you hear is from the past. It took time to travel from the source to your ear. Conceptually, if you were far enough away and had a sensitive enough listening device you could hear a word spoken 2,000 years ago. But the sound medium needs to be is stable. Which the atmosphere is not. Works with light though.
QI loves bashing brilliant men of a certain hue. And nobody is going to convince me that men like the sound of their voice more than women like the sound of theirs.
To be clear, the comedians come up with their own jokes. Typically, in a spontaneous fashion, as the topics are discussed. QI is not, like, handing them scripts to read - "and here's where you need to say this to insult white men". And you're just wrong, by the way, as the joke was a gender-based gag, which had nothing whatsoever to do with race in any way... except that you saw the skin colour of the comedian making the joke and then mentally added a non-existent racial component... because you're a bit racist. Personally, as a cis-gendered white man, I appreciate having my pomposity pricked because I have a sense of humour and don't have any pretentious delusions that I somehow "own the world" to be owed anything by it, you self-important moron.
Consider the number of men working on the radio since it was invented, as well as narrators, commentators, motivational and public speakers, tv and media reporters, news readers, singers etc etc and you should be convinced. Just because they become mutes when the subject of relationships comes up is more an indicator of their inability to properly understand and their general confusion regarding that subject, rather than a dislike for the sound of their voice.
I like how the 'husband' joke got the same reception a wife joke would've got. I like the consistency, I hate how the British public are slowly losing their sense of humour.

It may not be as insane as I first thought. I mean, there are a huge amount of variables that makes it not feasable as an experiment. But if we can use the mindset of mathematicians who calculate spherical cows... There might just be something to this conundrum.
Spherical cows in a vacuum, at that.
I was going to say something like this, good description.
I assume your thought experiment at the end is a joke, however I want to explore it.
Remember the volcano in the South Pacific (I can’t remember exact name location) but it became the biggest explosion ever recorded from space. That blast could only be heard 7,500 miles away. Or roughly a third of the circumference of the earth.
Now imaging making a speaker large enough and with enough power to amplify a voice to go further. Plus since noise is Omnidirectional and pressure waves follow the noise you would destroy everything within miles of the source in an instant. So unless you are Dr. Evil, I don’t think this will ever happen.

It started jokingly... But halfway through I actually started to think it through... It may be possible.
@@Mnaughten601
I'm sure the biggest 'Dr Evil' - the 'great' USA - is exploring the possibilities.
Imagine the background noise if sound just kept going.
So remember kids, don't set your sound down randomly or it won't turn back up for 40 minutes or more! ^_^
It's NewfoundLAND!!
The eruption of Krakatoa was heard clearly three thousand miles away off the coast of India. It’s considered the loudest sound in recorded history.
Wrong both times. It's not "new FOUND lund" or "New fun lund." It's "new fun LAND."
I always thought it was nu-fee land
And you're wrong too!
I love it when someone tries to be a smartypants and blows it!
It's not "new fund LAND" it's "new f'n l'nd" - you know... like f'o'c'sle.
That middle D is silent and the proper pronunciation is njuːfənˈlænd note the schwa and lack of D.
You're welcome.
@@tomstamford6837 Yes, I'll agree with you about the d, my late-night typo. I don't agree about the schwa. I've never heard a Newfoundlander pronounce it that way. As for the rest of your comments, the less said, the better.
@@juliansmith4295 Are you also going to write off your lack of proofing to late nights judging by your reply?
I stand by the rest of my comment, you were in full smarty pants mode. If you can't accept that people will call you out on that, perhaps you shouldn't do it and avoid commenting on YT.
@@tomstamford6837 Wow. Pot, meet kettle.
Jesus as a white man 😆 I always thought that was hilarious.
And with blue eyes.

You know how white guys are - always horny for getting representation in their stories, even when it's not appropriate.
Why not? What colour do think he would be?

First lines -- Joe Lycett and Shazia Mirza -- men like to hear the sound of their own voice... LOLs.
She’s so awkward, it’s delightful
She's thick as a 2 short planks.
Is that Judas in the image just holding a dagger and being like "shit i can't believe i'm really gonna stab this guy"?
Lol flat is absolutley correct the answer of sound waves is just one fact
You would think they could have picked an example from history of someone we *know* existed. Oh well.
classic comedy
If you said something REALLY loud it would count as an explosion, so . . .
So sound works like....a handbag?
but isn't alan right? does sound travel or does the earth rotate? a volcano can be heard around the world when it erupts
That little joke at the start would have been cut and the person cancelled if she were a man saying it about women... makes you think huh, now that is quite interesting :D
Incorrect. Say "Newfoundland" like you'd say "underSTAND": "noof-un-LAND" -- Never "lund".
I think I understund you.
0:48 I know it's nitpick-y but that image of Jesus isn't Jesus because it's based on one of two paintings, one by michealangelo and one by Leonardo da vinci, both based on the (male) lover of the artist. One of these men that the modern image of Jesus is based on was the son of the Pope, and he ordered all images of a bronze-skinned Jesus to be removed and his son's image to be put in it's place. So, basically, the modern image of Jesus is based on two queer men and the real Jesus was middle Eastern
All sound that you hear is from the past. It took time to travel from the source to your ear. Conceptually, if you were far enough away and had a sensitive enough listening device you could hear a word spoken 2,000 years ago. But the sound medium needs to be is stable. Which the atmosphere is not. Works with light though.
I don't know.
Only a woman can get away with saying that without catching accusations of sexism.
Nope. Jack Dee made a very similar comment about women in an episode with Roni Ancona and got away with it just fine.
NewfoundLAND
~ eye caught a feesh dis big and fed it to a tow-zand wid sum bred - tell all ur frenz ~
if sound cant be heard from the past how dose nasa get sounds from space huh?
Poor girl was slaughtered for her joke. Then made the best comeback 😂
Marconi stole his invention.
Alan may be the funniest man ever. Or at least since George Gobel died.
And yet if a man said that joke about a woman at the beginning of the video, guarantee she would of had a hissy fit
Was she a science teacher in America? Would all makes sense then...
newfinLAND
No, it's not NOO-fund-lend. Most people in the US pronounce it that way, but Newfoundlanders pronounce it noo-fund-LAND.

New Found Land not newfenlnd
15 seconds in and its unwatchable, what is it with the BBC and man bashing?
QI loves bashing brilliant men of a certain hue. And nobody is going to convince me that men like the sound of their voice more than women like the sound of theirs.
And here we see the male ego in its natural habitat, too fragile to ever take a joke.
I think the correct thing to say here is 'triggered much?'
To be clear, the comedians come up with their own jokes. Typically, in a spontaneous fashion, as the topics are discussed.
QI is not, like, handing them scripts to read - "and here's where you need to say this to insult white men".
And you're just wrong, by the way, as the joke was a gender-based gag, which had nothing whatsoever to do with race in any way... except that you saw the skin colour of the comedian making the joke and then mentally added a non-existent racial component... because you're a bit racist.
Personally, as a cis-gendered white man, I appreciate having my pomposity pricked because I have a sense of humour and don't have any pretentious delusions that I somehow "own the world" to be owed anything by it, you self-important moron.
True
Consider the number of men working on the radio since it was invented, as well as narrators, commentators, motivational and public speakers, tv and media reporters, news readers, singers etc etc and you should be convinced. Just because they become mutes when the subject of relationships comes up is more an indicator of their inability to properly understand and their general confusion regarding that subject, rather than a dislike for the sound of their voice.
Strange that you chose not to mention Tesla. Makes me wonder about many other of your facts...
Oh man
They used to invite funny people to be on this show.
I like how the 'husband' joke got the same reception a wife joke would've got.
I like the consistency, I hate how the British public are slowly losing their sense of humour.
Political correctness - the killer of humour.
In Canada, I believe it’s either ‘new-FOUND-land’ or ‘NEW-FOUND-LAND’, not ‘NEW-fund-land’.
new fun LAND

She’s a victim of comedy, unfunniest guest they’ve probably had
