Hi Dr. E.K.!
If we can measure the zeroth no time point, is their a way to multiply the Laplacian to show a function for the existence of an anti time equation in higher dimensionality? Mind blowing segment at 1:43&:44 seconds.
Thank you.🙏🏻

"[...] the Laplace transformation provide a method to EASILY solve differential equations [...]"
Every day I'm called Dumb in a different way
w/o initial conditions it makes them super easy, video didn't even break into all the electrical and mechanical uses it has. These videos provide excellent intuition.
Understanding the proof of something is way different than actually using it. The proof of a Laplace Transform is very abstract. Using the transform, however, is very easy. I am an electrical engineer and Laplace Transforms make solving circuits very simple.
I know that feeling
Good one. 40 years ago I learned this, but not used it. So I am as Dumb as you are. ;-)
@ebulating Easy for average University students. It may not be easy, for example, for Elementary school students.
Fantastic, I have no idea what I just saw.

Not only love the fact that all stuff is well visualised but also that every important information is both speaken and written for people who learn faster with their ears and for those who learn faster with eyes.
Great job
Thanks. Glad you liked my video.
Mathematicians in the past could only dream when they see this.
i just wonder how anyone came up with all this in the first place
those computers in hands of old mathematicians are no different than infinity stones with thanos
I agree. Only true badass mathematicians like Gauss and Euler would have been able to imagine this in their brains. It faaaaaaaaaaaaaar exceeds normal imagination skills. It’s like the difference between the distance earth to Moon versus earth to ☀️
@@ShahedVideo for such beautiful math someone needs poet mind and super awesome spatial imagination skills (for the inventing of such).
But with lots and lots of experiments I’m sure you would find some important new concepts too, not just people like Euler or Gauss.

sucks, change the explanation and remove the music
Hey, what playlists do you use for your videos? I would love to use them for studying!
It's beautiful... It's just corrupted by flawed computations of the base ten number system... so close.
@@jamesharbaugh5732 where
@@Stevobulfer it's inherent in computing as base ten needlessly creates irrational numbers with infinite decimals that must be rounded and denies division by zero to set a constant lower limit much like plank's constant. Out of all real numbers all are divisible by one as any number divided by one is an identity. Half of numbers are even or divisible by two, a third are divisible by three but this creates an infinite sequence with 1/3 because ten does not have a prime of three. 1/2 =.5 1/5 =.2, 1/4 = .25, 1/25 = .04... I try you can continue the mirroring effect of inverse exponental primes moving by decimal place. Pi is a perfect denominator as a circle has infinite slopes from n/0 to equality at n/n to n/0 and cycling through the four subplanes with infinite divisibility (like a pi chart, pun)... you just need to put absolute values on the Pythagorean theorem to better define i and render locality for more polarized locations. I could ramble on and I know you won't listen or care... It's nothing the video creator did... It's just built into the system. Base 60 was better but not perfect, a notional pi fraction would be and could bind infinity as well as introduce some cool number logic.
I used the Laplace Transform as a tool in my college classes, not knowing what it was really about. Finally, I understand what it really means. Thank you!
Glad my video was helpful. Thanks.
Fantastic. It really helps put equations into perspective when you can visualize the graph form through time. Wish we had today's computing power back in the early 90s... mathematics would have been more entertaining and easier to visualize back then.
Even though we have it i found this randomly on my own because our teacher just writes stuff on white board or shows some presentations with equations. nothing else. the subject is called cybernetics i was finally getting excited for some fun but got math 2 instead.
This videos are pure gold, I don't know how people used to learn this without youtube and stuff like this.
Thanks for the compliment about my videos.
Just in case anyone is curious, the music is: Liszt's Hungarian Rhapsody No. 2

Today, I have a Masters degree in science. Came here to thank this channel. It has taught me so much more about maths and physics than last 10 yrs of formal eduction and, also made numbers therauptic for me. Much much much LOVE. THis channel is literally a GEM of UA-cam!!!💓💓💓
Thanks for the compliments. I am glad my videos have been helpful and that you have enjoyed them. And congratulations on your Master's Degree.
Love your videos. This one way over my head, but I have learned a lot from the simpler ones. Thanks.
Excellent. Beautiful graphics. I hadn't thought about this stuff for decades. It brought it back to me in the most beautiful way.
Thanks for your time invested furthering our understanding and knowledge, Eugene Khutoryansky. Appreciate Kira Vincent's excellent and engaging speaking voice.
Thanks for the compliments.

One thing Eugene taught me is that sine wave is not that 2d wave which we are taught, but actually circular motion moving with time. So powerful and elegant concept to know!
Thank you so much☺
Thanks.
Careful. The spiral you are seeing is actually two sinusoidal waves being added together according to Euler's Identity: e^(iwt) = cos(wt) + i sin(wt)
In order to get a flat sine wave from those complex exponential spirals, you need to add a positive and negative version so they rotate in opposite directions like this: 2 cos(wt) = e^(iwt) + e^(-iwt)
@@AlphaCrucis The 2d sine wave is a projection of this spiral. Even Euler's formula gives a point on a unit circle in complex plane. e^(iwt) is actually a point on a unit circle that changes w.r.t. time. Now if you think that this point not only rotates but also moves out (or goes into) the plane of rotation with increasing time, you get this 3d spiral.
When you add the conjugate of e^(iwt) to itself, only the real component of the complex point remains; the sum is twice the real component of e^(iwt). So it appears that only x coordinate is changing and there is no rotation. But there is rotation, just that it is confined to one dimension. So my point was that the sine wave we are taught is what we see when this spiral is plotted on a flat 2D surface like screen or paper. Maybe we can confirm it with holography.
In fact, I believe in higher dimensions like quaternions, this would relate with direction cosines. In two dimensions, sine and cosine are direction cosines of a point.
This is a great animation.
It's for the first time, I found such a lucid explanation of Laplace Transform.
If you haven't seen them yet, I highly recommend his videos on the wave function and Fourier transform.
Damn, this almost brings a tear to my eyes. Definitely a sight to behold.
Thanks for the compliment.
You sure it's not the Liszt piece you're reacting to? This one has had that effect on me before.

I try my best. Hope you like my music
Excellent video! I really appreciate understanding these concepts on a more intuitive and deeper level, and this video definitely helps to achieve that so thank you.
you are doing soooo great not just well , the creation of videos ,the knowledge needed for those videos , I've watched some and you are astonishing me every time, good luck
Math is awesome. Good job La Place! Got me through electrical engineering without being a math whiz.
Wow men ! This is just crazy. I can not imagine how much time you have taken to make this incredible video. Honestly, it is amazing. I am just very curious to see what is going next, when you will want to explain transfer function and laplace transform together.
First time I saw this video when I was in K-12, I had no idea what you were talking about.
But this is the second time I watch it as a 2nd year engineering student, your video has been of great help.
This video is so helpful. Being able to visualize different functions in 3D gave the lightbulb! Thx
This is amazing and motivational to continue learning math. Thank you for awesome work!
I have subscribed to your channel and I truly believe that this is going to become one of the best channels ever. Ever. Just keeping work on your videos and you never know where you will be in a few years. Cheers! Btw, what do you do? Are you a teacher?

Amazing to see how easily this video explained the subject.
Of course, I haven't understood a bit.
Arguably the most important math/physics channel on UA-cam. Thank you so much Eugene.
Thanks for the compliment.
I really wish if more videos like this were made for the more basic and fundamental concepts in mathematics.
This will bring more viewers and help those who already know the basics to understand it even better with the 3D animations.
I also have videos on basic topics, in addition to videos on topics like this one.
really cool video as usual Eugene.
Glad you liked it. Thanks.
Just in time for my class on transforms! Thanks again Eugene!
Currently taking Process Dynamics and Controls where we use Laplace transforms on the daily..This video has given me some spine bone chills!
This is really beautiful, thanks! I appreciate the deep understanding necessary to create 3D visualizations
Thanks.
I have always thought about similarity between laplace transform and fourier transform. This video is so descriptive. Thanks a lot
Fourier is a subsection of Laplace
thank you eugene...for your videos..i am so happy while watching it...when my prof said...i could'nt understand at all......and your animation quality has also increased.
Another amazing video thank you! I just took control systems and math physics for my electrical engineering degree last semester and had a very hard time conceptualizing the different system responses, makes way more sense now!
Thanks.
Laplace had a level of genius right up there with Gauss, Maxwell and Richard Feynman!
nobody is as genius as gauss.. all the other people you mentioned combined are far inferior to gauss' genius
True but you didn't mention euler and that's understandable because he is from another dimension
Lagrange is the real beast
Y'all know your geniuses alright xD

Wow. Haven't learnt what Laplace transform is but now that I've seen this, I think I got an idea! Great job! Love the cheery music going on in the background haha
I love everything about these videos. The subject, the visuals, the captions, the music--it's perfect!
Thanks. I am glad you like my videos.
Music... perfect... as I expected it to be.
Amazing, I'm really excited after watching the visualization. The Laplace transform is useful for analyzing continuous function, yet it can not be used for discrete signals which need z-transform to analyze. Can you make the 3D video for explaining z-transform? Thanks a lot.
Dear Eugene
Your channel and your videos get the maximum number of responses in shortest time.
It's my third comment that too before 24 hours of it's posting.
But you know I am dumbfounded.
Lost my words for the appreciation of your videos.
What ever they are.
These videos will be greatly appreciated by future engineering students.
And as I always say keep seeing physics.
Sincere regards.
Thanks.
Very nice video! I have already taken a course on Fourier transforms, but not yet on Laplace transforms, so I did in fact learn something useful from this video. Keep up the excellent work, Eugene.
Thanks.
This was completely amazing, you just opened my eyes. I'm so grateful for this.
Greetings from Panama.
Thanks.
those of us undertaking electrical engineering in the last century would have benefitted vastly if these visualisations existed then
8:35 Computer says: forget it, this is too complex, not calculating the dots anymore 😂
Lolz
COMPLEX you say?! :)))
These videos you make are both such wonderful tools for learning, and are just beautifully made.
Thanks for the compliments.
Brilliantly simplified, elegantly illustrated! Superb, as always!
Thanks for the compliments.
You are awesome! Could you continue this video series with a video on transfer functions? O would appreciate It a lot
Thanks. A transfer function is just the Laplace Transform of the unit impulse response.
Dear Eugene Khutoryansky , your videos are brilliant .... its a real contribution to Maths & physics ......Keep going..... I use your methods to teach in my class rooms people like them..... you have inspired many people through your brilliant imagination and knowledge..... thank again for explaining Laplace in your own style.... Hats OFF
Thanks for the compliment and I am glad that you like my videos.
I've always wanted a visual representation of the Laplace transform. Thank you so much!
You are welcome and thanks.
your 3d works are wonderful, thanks a lot. keep making more videos.
This is better than undergraduate engineering class of MIT and Stanford together
Thanks.
the MUSIC is poorly chosen, Bach's sonata would have been SO much better. In fact the music completely destroys the understanding. How could he have been so callous! How could he not have paid attention to the music. It's so wrong. (LOL).
I did not know that a class at MIT was so deficient.
Nice humble brag
USAss is so crap
Hi Eugene,
I am a retired EE, it has been 40+ years since I studied Laplace transforms.
I enjoyed the video and yet it is still mysterious as well as wonderful.
I would enjoy seeing applications like multipole LRC circuts solved in this manner,
as well as the duals in mechanical Mass/Spring/Damper systems.
For extra credit - adding an amplifier to make a notch filter would be interesting.
---Also what programming language did you use to create the video and is the
code open source?

This is exactly a clean explanation of the Laplace transform. The video doesn't simplify it it to make it user friendly. This video describes it in all the details.
This is a video that must be in every classroom because it doesn't dodge the problem by intuitive explanations. Math is exactly this, complexity and the analysis of behavior.
This is an outstanding video that fully describes what is going on.

Это просто потрясающе! Подобные визуализации должны стать частью образовательной программы!
да, согласен.
Когда то, безуспешно изучая верхнюю мать- еë-матику, я игрался в Maple V рисуя графики простейших алгебраических и тригонометрических функций.
Не скажу что в школе учили плохо, у нас была замечательная, влюблённая в предмет математики преподавательница.
Но, только появление персонального компьютера и дисплея в моей жизни смогли визуально растолковать закономерности и зависимости в формулах.
Я начал "чувствовать" поведение функций типа cos 2x или e^sin(x^2).
Успехов не достиг, но уважением к предмету проникся. 8)
I am grateful for your existence.
Thanks. :)
Another wonderful video that explains a concept at its core. Thank you very much, Eugene! What made the video worthwhile are the graphics along with the explanation. Yes, I had to watch a couple of parts two times to follow you but that is because I haven't dealt with the Laplace Transform in a while and also because when I studied it I didn't have your wonderful videos that helped me visualize how the functions were actually being generated. Yes, I passed all the tests and did very well on my finals...but I didn't quite understand what was at the core of the Lapace transform.
Thanks for the compliment about my video. Yes, passing the tests and actually understanding the concepts are two very different things. Our education system focuses on the wrong things.
@@EugeneKhutoryansky 🎩 off for this cool admitting of facts concerning our education system! Like this we can finally make up to half the population love our subject! 😎 🥂
Yet another beautiful video! This is art Eugene! Keep up the good work! I suggest a video about microwaves in Transmission lines,standing waves, impedance matching, etc. Thank you!
Thanks. Perhaps you have already seen it, but I have a video on transmission lines at ua-cam.com/video/ozeYaikI11g/v-deo.html

Nice visualisation in 3d. Amazing to watch and learn the concepts. Took some ideas from your channel for my class videos. Thanks and keep posting 😃😃
There is only one other channel I've come across here in youtube that does animations like this, 'Welch Labs: Imaginary Numbers are Real".
I wished you did a calculation at the end to show how this is used to make sense of a nasty differential equation where you transform and invert to solve. Great job.
Eugene i remember when i was like the only 1 watching your videos. Im so proud.
is that all about Laplace Transform ? I still didn't get it , when the part 2 be released ?

I always wondered, what the hell is it for me to learn this? I studied food engineer degree I didn't know where I could apply this. I finally see and understand what works. Incredible as I can now give me an idea of how fascinating mathematics is with this vídeo. Greetings from México.
Pure genius, beautiful graphics. Although I understood only about 5% of the material. Now I know just how little I know.
Every electrical engineer is familiar with these concepts, sadly 😢
Nothing interesting except the classic music
Hungarian Rhapsody yeah!
But of course.
This is very enlightening, now it got me wondering if we could create a transform even more general than Laplace, where not only the amplitude of the sines can vary but also their frequency, like the summation of infinitely many frequency modulated signals, but that sounds a little crazy
2nd year physics student here, only used them for solving ordinary differential equations so far. Never seen them visually represented before
Nice visual effects . But please take the time to explain what you're talking about, otherwise its just as another comment says: colours with music

Thanks.
thank you so much! your videos explain fundamentals very well
I couldn’t follow this. Something is missing. Like what is being transformed to what.
there are 2 functions here, A function which takes some time value(I'll call this f(t)), and outputs a value for some input of time. Then there is its "Laplace transform", which shows the "frequency" of f(t), given some complex number s(I'll call this function F(s)). However, there are 2 different transforms this video goes over, the first transform the video explains is the transformation from F(s) to f(t), the second one is from f(t) to F(s).
somehow the video doesnt actually show how the calculation is transformed. thats what i actually miss in those videos. without previous fourier and some math books i wouldnt know what she tries to show. with a real equation going over all the animations would be more interesting. so its only showing the two parts.
@@DarthZackTheFirstI the video literally showed both of the integrals you need and explained every term.
