The wildest thing about chaos theory is even the microscopic smudges on the mirrors caused by your fingers when you made them would also be a variable that causes a significant change later on because it affects the reflection/diffraction of the laser. This would be in addition to the variable change in the angle. That’s chaos for you
@Orange Jello
Butterflies are troublemakers.
Plus the natural curvature of the tubes, plus the placement, plus whatever particles are in the air...
@Orange Jello Those bastards !
Life, uh, finds a way.
@@infinitytoinfinitysquaredb7836 says Android on bridge of the Raza !
"I've some flexible mirrors and some toilet paper rolls"
I've never been so excited about science 😄😁
I need both!
You do realize that the term "flexible mirror" is an Oxymoron !? ;)
Cool
Now you will
@@blinded6502 plz explain?
you always find the coolest ways to demonstrate things
110th like🥳🥳
True
@have a nice day 😘 yeah coz thats all about being all knds of "special"
Uh this idea was pulled from someone else's video he just took it and made his own irl
Demonstrate black hole in your home 😁
You should definently try this experiment with adding one of those Lego multiple gear machines (that do full spin in 100 years) to slightly change direction of laser
That's an amazing idea
bro 300 iq
Or just do a timelapse of a single full rotation!
@@RJiiFin it won't complete all 100 gearbox in a lifetime. It will be complete when the universe ends.
That's a gear reduction
Next time use a smoke machine for the laser path, great video!
@have a nice day 😘 bot
This was my first thought! Maybe we'll see many lines crossing!
Oh, no, then we would have… smoke and mirrors!
@@tamask001 but this also causes even more scattering
It might just diminish the light instead of scattering because of the quantity of redundantly contacted particles... What if, depending on what the fog was made of, it culminated into plasma and ignited! Hehe.
Because the beam has width, wouldn’t using mirrors with a larger diameter reduce the resulting 360* result? Giving you a closer result to the computer simulation.
Yes but you'd also need larger movements of the laser to achieve a similar effect, though still probably worth. Do bear in mind that the mirrors aren't ideal mirrors either, there's going to be scattering and some diffraction even then.
IF you would hit the border of a cilindrical mirror, a refraction would happen making it spread again
@@BlaxeFrost-X yes I agree with you that is why I used the word “reduce”. And not eliminate.
The spreading effect would probably multiply so much that it might not even make a difference. Worth testing out though.
Set up an experiment and do the science ! Record it all. Who knows, you may find some new thing that getz your name on it.
I've been subscribed to Nils Berglund for several months; it's crazy to see a crossover like this since Nils's channel isn't huge or anything
It has blown up on RUclips shorts for some reason. I've loved those animation for months too so this crossover is wild.
I was here since years
NileRed? They have over 2 million subs.
@@MisterMister5893 no, I'm talking about Nils Berglund, the person whose video this experiment is based on. His name is shown and also spoken out loud. It's also in the description. I guess you just skipped to the end or something?
@@Fatso-to-fit I wasn't talking about the Action Lab channel, I was clearly talking about the Nils Berglund channel, whose video this is based on. Are you saying you've been subscribed to him for years? He put out some barely-viewed videos 6 through 8 years ago, but then had a gap of about 5 years until he started uploading videos again 5 months ago. Are you saying you were one of his original subscribers from when he first started uploading videos?
Thanks for trying the experiment irl. Have you tried using fewer cylinders, maybe 3 or 4? It might give a more localized spot.
Thanks for making your video
Your video was incredible
bots?
At the end of the video he showed that after just two cylinders the beam had spread out to nearly 180°
Dude doesnt even read his comments to know the guy who he took this experiment from - stopped by to comment lol 😆
You could repeat the experiment angling the light source upwards slightly, and then each strata of height would represent the distance travelled before finally emerging from the mirror maze. You can see this effect in your video, but it could be made more pronounced.
Ooh now thats my kind of cool
You should use Fog so that we can see the whole path of the laser
good idea!
Old TheActionLab: Haha cool science thing!!
Modern TheActionLab: I am going to cause a tornado across the world...
tornados will occur anyways. thanks to the unpredictable nature of the butterfly effect, there will probably no way to determine the initial cause :-D
Why can't butterflies just mind their own business and quit effecting things
Why do you have internet access
"All simulations carried out simultaneously." That sounds similar to the idea of a quantum computer.
Aren't we all in a Simulation? Heard of Matrix?
LOL I was going down to write that ..
@@GMishx egg
Technically this shows the power of optical computation more than anything else, I think.
In this context, it would be more like the idea of parallel processing with lots of CPU cores, rather than any quantum effect.
You should have made the cylinders with a much wider radius to reduce the spreading at each hit & used different color/width lasers.
No, you
Where would he find such large toilet paper rolls?
At a store for GIANTS?
@@PowerScissor one could just use whole rolls of paper towels or toilet paper.
@@PowerScissor There are other things that are cylinders besides toilet paper rolls
@@hakrj12 exactly 😂👍
What's very interesting are the bright streaks in a few places. Those would represent the input angles for which the exiting beam only moves slowly.
Or alternative, just spots on the walls that get hit from multiple different exit locations and angles.
@@TiagoTiagoTyup. You got the real answer.
I'm 52 and I enjoy every video you make. Thank you for what you do. I learn a lot.
Brilliant as ever…if you point the laser down at a slight angle then you should get a series of horizontal bands. Each band would be indicative of the number of reflections. This would separate much of the dispersion we saw on this video. I’d love to see if it works!
Hey @the action lab! I have a question. Is it possible to dry a wet cloth in a vacuum? When the pressure decreases, then the boiling temp. Of the water will also decrease right? So will the water in the cloth get evaporated in a vacuum? Can I use the vacuum chamber to dry my clothes instantly? Also, would you mind making a video on it? :P
I have a vacuum chamber and I've tried drying mushrooms with it and it doesnt work very well and it takes days of constantly releasing the air and re vacuuming it than releasing and so on for it to work but it does seem to make it so no bacteria will grow but I think freeze dryers are probably the only way that a vaccum is gonna dry something very well!
It will evaporate quicker at first, but due to the evaporation it will cool down (the hotter molecules will leave it, while the colder ones stay in there) This will go on until it wont evaporate that quickly any more and then it will dry slower again
@@GoldenBoy-et6of you should add heat source such as infra red light or other light might work. Because in vacuum, all heat transfer execept radiation is gone. While evaporation require heat, initially the item dried will drop in temperature until the rate of evaporation also go down to equalize the heat absorbed. You may use heating surface, but the heating contact area may be reduced when the item wrinkles as it loses water. Freezing before vacuum drying is just a way to maintain the form factor and integrity of the item dried.
@@GoldenBoy-et6of did you try putting the mushrooms under a lamp? Good luck with your drying
I think an issue is that the moment any water evaporates it becomes a gas, which then adds pressure, meaning you'd constantly have to be pumping air out of the vacuum chamber, meaning your vacuum pump would constantly be sucking in water vapor which probably wouldn't be good for it.
There’s got to be a way to use this as a premise for a functioning cloaking device, like from Star Trek. Somebody needs to figure out mathematically how to arrange the cylinders in order to maintain the effect while having a large open space in the middle.
We could use genetic or evolutionary algorithms to evolve such a pattern of mirrors that cloaks anything within them. Would actually be relatively simple, since the only parameters that would need to be verified would be the positions and dimensions of the cylinders.
@@R2Bl3nd do it
@@Chris-io2cs why not, might be a fun little project
What's a cloaking device?
@@sudarshandas4270 Cloaking device is a science fiction idea for creating the illusion of invisibility by reflecting light around an object so that the observer sees what’s behind the object rather than the object itself.
5:52 is such a good visual demonstration of what you were just explaining about the width of the laser causing the 360° spread effect.
So you could also see someone behind those cylindrical mirrors even if you don't directly see them.
You can see something, but since light rays are scattered disorderly, it would not make any real image.
This is cool to see and would’ve been really awesome with a mist of some sort to see the path of the beam viewed from directly overhead.
See, this is why even if time travelling was possible, the butterfly effect wouldn't allow you to change the timeline into a desired one. Even one single particle you interact with would change everything.
Good this traveling back in time is impossible we can only manipulate time to slow down or speed up we cannot reverse time as time is the rate of the universe which we perceive relative to everything
Like which egg and sperm get randomly fertilized. Tiny differences in position affecting who even gets born.
This would be fun to do with artificial fog as your “screen” instead of your white panel. This would hopefully enable to get a clear view of the reflections from a zenith viewpoint and give you more options for the light source position.
In effect the simulation was correct, just not accurate to reality, irony: the butterfly effect effected the real life experiment, as in there was an unexpected result, very nice
When watching this I was thinking about how one could have a laser which only outputs a beam that's the same height and width as a photon. That way you could guarantee that the laser beam would always travel in a completely straight line I think. Not sure if that technology exists though.
@@R2Bl3nd We can do that, but you won't be able to see where it hits. It won't produce enough light for the human eye to see.
@@SlimThrull humans can detect single photons though, if it was a continuous stream of them surely it'd be easy to see. It could be just as bright as a regular laser but just smaller. A bunch of light concentrated into a small area wouldn't be invisible.
@@R2Bl3nd Even assuming we could, the photon hitting the container won't necessarily hit your retina. Even with minor scattering from the atmosphere this would occur often enough. Add to that the fact that the container is going to reflect them in fairly random patterns to begin with and the likelihood of you actually seeing that photon becomes pretty close to zero.
While our eyes can detect a single photon, they generally won't fire a nerve unless 5 to 9 photons hit within less than a tenth of a second. So, no we can't detect a single photon by itself. We can however detect 5-9 if they all hit within a tenth of a second.
Edit: Clarity.
The simulation can just used multiple point lights right next to each other to be a bit more realistic
I thought this guy was just some dope at first. His voice sounds like he's not serious and just doing random things as a joke. But now I see he's the real deal and his passion for science is amazing. It turns out he has a PhD is science or something. I hope he ends up being remembered as a real inspirational educator like the Curriosity Show men and not forgotten as just another RUclips content creator.
Don't judge a book by its cover
Amazing illustrations of the butterfly effect!
The fact that you utilize so many different aspects of science in your experiment / videos is remarkable to say the least thank you for this content so much as I feel it will be a standard and Future science teachings in my mind!
the experiment needs a non returning source ,maybe shooting small BB' s out of a gun and seeing where the pellet bounces off and hits the exterior wall would be better
these just keep getting better and better
*With enough information EVERYTHING could be predicted*
*If you think about it, everything is predetermined since the big bang*
@Batata zy I believe calling something "random" is a placeholder because we cant predict it or understand it yet
@Batata zy interesting
Could it measure the gravitational effect of lets say my hand if the lasse was actually my hand ?
(gravitation bending light)
I say yes but you won´t have the instruments to measure such a slight change. We are talking about a millionth of an arcsecond presumably if not less
@@sikliztailbunch Hmmm, okay, kinda dissapointing, what about the moon though? would the light move depending on day/night?
@@yaykruser Since light is affected by gravity, I guess so. But since we as humans do not really feel a difference between day and night in terms of gravitation, I guess even that would make a barely measureable difference. Keep in mind that even a planet bends a ray of light just very slightly. It takes a very big amount of very condensed mass to bend a ray of light significantly. A black hole for example.
On the other hand, it depends on how far the light ray goes. Research facilities use lasers over very far distances to measure even slight gravitational changes. We are talking tens of miles.
Your channel name should be the 'best explanation lab', because the way you just explain and give examples it becomes easy for us to understand it. Love your videos sir
Finally, a use for buying all that bog roll in lockdown.
Using the lexicon "bog roll" means you're british and possibly northern,
I *just* saw this video. And then i see you replicating it in real life. Thank you for actually doing Experiments on the things the people want to see
Ahh so this is like that pathfinding in **insert game with NPCs**
Definitely the best video of describing the butterfly effect!
i must say that this is middly infuriating that he bought empty toilet paper rolls instead of keeping the used ones :{
We should cancel culture his channel, and call his boss
@@jamescollier3 hmm how about send him 9trucks full of toilet paper ?
Angle: Changes 🤏 much
Laser beam: Haha go brrrrrrrrrr
I’m at 4:30 and think the simulation didn’t account for the defusing of the laser (getting slightly wider the further it goes).
The simulation has only taken a single beam of photons.
That pendulum experiment really astonishing
Please stop testing the physics engine. My FPS irl had dropped a tonne lately.
Spread out the tubes and make them larger diameters
Would love to see this effect with some smoke!
Awesome! And now I'm ready to encounter the super-shortened / vertical version months from now.
That double pendulum video superposition reminded me of that experiment in which a lot of metronomes running at the same tempo, self sinchronized when put all together in moving board... could we achieve the same effect with double pendulumns?
my friend and i did this one night in my room when we were playing with lasers. we shined them at round things and a glass bottle on the table to see the light spread out.
Really needed a top-down view like the simulation to appreciate the path and deviations the laser took
Coolest thing to me is the fact that wheb it goes 360° you can actually see different lines, corresponding to different reflection patterns
In fact the best demonstration is the different height all the splits of the beams come out at, showing the beam was not level and the further up or down the different levels shows that particular part of the beam traveled further than the parts that hit the wall closer to the level of the original beam at its entry height.
Perhaps would have made a more illustrative effect with a bit of smoke? Also perhaps space the mirrors out more, and use less of them, adding one at a time, then wiggling the laser round. As you add more tubes, you'd see the effect become more and more chaotic.
i moved out and year after that i was invited to a beach by friend family because they were visitin the town i live in and at the beach there was this marine rescue team stand and i quicky took a picture about the stand and didnt think about it anymore that day. few days later i read what the stand said and there was a time and adress to a recruiting event. i went there and joined the crew and now thats third of my freetime and its absolutely amazing hobby (i like to be able to work in cold, heavy rain, hunger, dark and big waves). i would call that a butterfly effect
in fact you can see even better on your experiment, a change just the size of the laser (a few mm) can drastically change the outcome. The little changing of the start conditions of the photons trough the thickness of the lazer made them end up trough the hole 360º of possibilities.
This is one of the coolest things I've seen, and it's essentially just paper rolls, tin foil and a laser pen! Kudos to you!
Great demo of refraction, reflection and defusion too.
Go/Weichi is another fantastic example of the butterfly effect; the first few moves set the path for the whole game, and a mistake in the opening is often not felt until the endgame.
This could make a very pretty lamp. Wouldn't be bright enough to read, but definitely nice to look at
These need to be so much longer 🙌 love the videa. Thank you for sharing 🙏
Such a cool experiment. Would love to see it in ultra slow motion to see if it can capture the laser light bouncing around.
amazing! 👍 its just the sum of angular movement.... just one angular displacement whil projecting it far, makes huge difference.... and here you are adding several ones.... one of the best ways to explain the butterfly effect.
I wonder if you could minimize the effect of the beam width by using much larger cylinders (55-gal drums might be a bit extreme, but you get the idea). I'd also love to see what a fine dry ice fog would do to to show the beam's path as it changes..
I need this as ambient lighting for my room. Imagine the cylinders and lasers ceiling mounted and programming the laser to slowly sweep across with the clock. Every minute you will have a totally different pattern along the top of your walls.
Actually the fact the beam spreads out so much is really proving the butterfly effect.
At each moment the resulting illuminated area represents the spectrum of all the possible landings that originate from each infinitesimal point emitted from the light source.
Some zones end up being brighter than others because the chance of a starting point to end up there is higher.
I did not know that the guy from "that 70's show" was this smart, he grew up to be pritty handsome to
This and insanely slow Lego gearing videos would be a perfect marriage.
My uncle worked with darpa and OSS for 40+ years and he said they experimented with reflective spheres and lasers back in the 1970’s to make a defensive shield for incoming missiles. He said basically think of the most advanced thing you can imagine and then go forward 50 years into the future and that’s what they’re working on. They have technology so advanced that right now if china or Russia etc started a war, darpa could unleash an artificial intelligence computer that flows/feels through the atoms of the air and could all at once explode chinas bombs while blacking out their power inside their entire country at the same time.
It’s like Japan not understanding what a nuclear bomb is and then all of a sudden they’re missing entire cities.
I just want to say i totally appreciate you for doing these experiments and showing people how the world around us works and exposing people to concepts of science they would otherwise never know anything about 😁
This channel does the coolest things.
Use bigger cylinders with proportionally bigger gaps. Making the environment bigger should “reduce” the scatter effect. Also try adding smoke, could be interesting. Great bids as usual!
spread the mirrors out a little! with them so close together, it’s no surprise that diffusion ends up making a 360 of light; i’m sure the tolerance is tight, but it’s worth a shot :) i might have to build this one at home just for giggles. Thanks for the excellent videos, as always! cheers!
You should've put fog or smoke around it, would have been cool to see what the light was actually doing.
you seem like a kid playing around and i love that
You can try a collimator to narrow the beam.
Also proper cyllindrical glass mirrors by spraying mirror chemicals onto regular glass rods.
And a more regular spacing, all to achieve maximum fidelity to the mathematical model.
Great explanation. I recommend adding haze or fog to your experiment. That should allow you to show the complete path of the laser.
Do you think there is a slight bit of diffraction in the mirrors and not just the width of the laser that has width?
Can you do that simulation but with a “wave generator” pattern instead of a laser? I wonder if you would get the 360 right of light output.
*The only one teacher I love the most*
Not only are the mirrors flawed due to fingerprints and smudges that will alter the results, each one has an edge where the end of the wrap is, and paper tubes are rarely perfectly round or consistent from one tube to the next.
I don't know why but that just sounds like the best entrance to a video I'm going to be doing experiments with lasers and cylindrical mirrors that's just fucking awesome
I feel that the orientation of the mirrors need to have a wider and more consistent spacing. In the simulation, the space is wide enough that once the beam hits the first mirror, the beam is able to travel past mirrors, before hitting one on the incident angle. Right now, your beam is hitting multiple mirrors and scattering.
Completely unexpected conclusion. Very cool!
There are actually three effects at play here that conspire to create the width of the beam.
The laser isn't a perfect point source, and is emitted multiple (many) photons wide. The laser isn't perfectly coherent and very slowly diverges (like a tenth of a degree at most) and scatters off the air.
And even if it were a perfectly coherent point source and the experiment were in vacuum, the fact that photons themselves have a width (because Heisenberg, among other things) and the atoms in the mirror inherently form a lattice somewhat akin to the cylindrical mirrors in miniature, plus a few other quantum considerations, will always introduce some small degree of scattering.
This is a great representation of the focus of the conscious mind and where it will lead your life if you simply change your focus.
That is a really cool visual effect.
that was super cool! i bet a fog machine like they use at a club or minibar would make the beam super visable! or even some vapor from an ultrasonic fogger!
Means minor positive changes in our life can make us successful in future...
And same thing is true for negative changes...
So, it's our decision what to choose.
Great experiment! The only thing I can say to add is the notion that some influencing factors (mirrors) are small while others are big. Also consider how these factors in real life change second to second, so they should be in continuous motion. To duplicate anything under those circumstances further exacerbates the impossibility of such.
The image produced by the experiment reminded me of a gravitational lens image.
Just a small suggestion, try filling the room with smoke and spacing the cylinders a little bit apart and getting a top down shot, I think that would really show the path of the kaser changing clearly
Again, my man is really challenging the physics of the simulation we live in
Very nice presentation!
And when you think that some physicist continue trying to prove it's not possible to have hidden variables that can generate random looking outcomes ...
Team up with Nils for some wave propagation experiments!!
I usually like your videos however I really loved this.
Nice background tunes..❤
Brilliant vid yet again 👍
Yoooo a Nils Berglund shoutout hell yes
I'm fairly confident you manifested every possible reality in a single physical plane here...
Even if the laser had a very narrow beam, the natural flexibility of the mirrors and the laser stand would spread out the beam.
Wow very interesting loved it
I was here
You could have used a fog machine to improve the effect, even so it’s very impressive
That was awesome, may I suggest setting the cylinders at different grid spacing to accommodate the width. Also hitting an interior cylinder first. And get a reflection from one to another.
