Finally!!! This was my Eureka moment. I've studied Fourier Series and Transformation multiple times during my bachelor's and masters in computer science and each time I only learned the technique and not _why_ and _how_ it's used. This is the best explanation and intuitive explanation of Fourier Series and Transformation I've ever encountered. Thank you so much Jade! You must've researched really hard to come up with the examples and simpler words to explain this. Thank you once again ♥️

When ever I watch one of Jade's videos i feel like I am watching and adult version of Playschool (an Australian kids educational TV show) there is a level of enthusiasm and 'you can do this' that comes through that is so wonderful. I often get lulled into a false sense of security and zone out and then have to go back and re-watch remembering that I'm not quite as smart as she makes me feel. Jade I love everything about the way that you do what you do it must take a mountain of work so thank you so much.

Being a telecommunication engineer I perfectly know how Fourier transforms are ubiquitous, as they are necessary for signal processing an electronic communications. But it is fundamental also for buildings and mechanics because the analysis in the frequency domain allows to understand how materials and systems behave under given inputs. I think nowadays it is as essential as basic math operators like +, -, /, *, etc....

This concept blew my mind the first time I learned about it at uni. Until then, I had never realised, or even considered you could transform from one domain to another. I'm now an audio engineer, it's astonishing how ubiquitous, useful and practical the Fourier transform is in the field. I liked the tie in to real world algorithms at the end. I would like to see a video about different sorting algorithms if possible! My personal favourite is the radix sort.

Calculus in general does that, when you think about it. Like with simple kinematics: you can describe an object's motion in terms of position, or take the derivative to describe that same motion in terms of velocity, or take the derivative one more time to describe that same motion in terms of acceleration.

My favourite usage, and indeed my introduction to, the Fourier Transform is in Mersenne primality testing. The most computationally expensive part of some primality tests is a squaring of a very large integer. By representing the digits of the number as time-series array, taking the fourier transform, squaring the individual elements (this step can be done massively parallel, hello GPU computing!), and then transforming it back, we have effectively squared the original number in a fraction of the time.

Fourier series works mainly on `periodic' functions. Aperiodic functions are treated as periodic functions with their periods tending to infinity. In this case, the Fourier series (in the form of summation) takes the form of integration, which is known as the Foruier transform.

I first learned of it back in the early 1990s when I was using a "granular synthesizer" that would let you draw a picture and then it'd convert that into sound. It took over 20 years for some software to duplicate that synthesizer. BTW, my wife and I bought your t-shirts and we love them. Keep up the good work.

Fourier series & transform are incredibly powerful instrument that can be used in most of our aspects of life. While it's actually not perfect - as it doesn't provide the best possible solution (unless you're ok with applying more and more sine-waves to infinity) it's surprisingly powerful in practical terms. One (of the many) curious things about it, is that it's in the core of Heisenberg Uncertainty Principle (HUP). That's can be very confusing to most people, as most think that HUP is actually related to something physical in the nature of the quantum particles (I thought so too until not long ago) and one of the most popular explanations is that you can't measure a property of a quantum particle w/o interacting with it and affect its other properties in doing so. But this isn't at the core of the problem - it's a practical measuring problem (that we might not ever be able to solve), but doesn't actually say much about the nature of the quantum particles - ie what they do while we're NOT observing them. ... anyway the solution to this problem is still a mystery, and we might never find it (many scientists have already given up, and prefer to "shut up and calculate" what they can), but the current truth about HUP is that physicists are using Fourier series & transform as a tool for their measurements and the uncertainty is actually embedded in the HUP itself - it's a limitation of our Math Tool (no matter that it's indeed really, really powerful otherwise)! It's not necessary limitation of the universe (at quantum level)! That's pretty much the same question - Did we discover Math or did we invent it? - but with quantum physics seasoning :) While in most cases it's not practical to wonder about the philosophical aspect of a given field of science, it's extremely important imho that it's never ignored completely, as most people start to believe that what Math is telling us is what Universe actually IS ... which might be the case sometimes, but isn't really necessary true. Math is like a keyhole and if we sometimes see things take keyhole-shape (as we're looking thru it) doesn't mean that we're seeing the whole picture and that it's indeed their real shape.

Great video! One neat trick to solve for series is to consider the derivative or integral of a series that is easier to find. For example, once you have the square wave series, you can trivially solve for a triangle wave, by doing the simple integral of each sin term. That’s because a triangle wave is the integral of a square wave.

Nicely done, Jade. I was introduced to, and began using Fourier Transforms in the 1970's. One of the things I learned is that one does not need the basis vectors to be orthogonal provided they are non-degenerate. As long as each basis vector cannot be described in terms of any other basis in the set, one can still get an absolute description of the phenomenon! When one is examining Complex space, this trick can sometimes massively increase the number of signals that are actually observed. (fyi, Real life detectors simply cannot see spectral lines that have a non-zero imaginary component.) This technique was used to double the observables in early MRI spectra.

Great video and it certainly will help to get a better or more intuitive understanding of Fourier Series and its Transform function. One thing I would like to add though, is that is isn't just a tool. It also has a very real-word importance in (physical) systems. Whenever a transient signal travels through a system, its ability to propagate or sustain itself will depend on how that system responds to it. In physical systems, electronics being a particular important one, signals with different frequencies will face a different resistance/impedance. Those who ever watched a high-frequency digital square wave on an oscilloscope may have noticed that it wasn't quite square. Instead having oscillations around each vertical rise and fall of the signal, similar to the reconstructed square and saw-tooth waveform in this video's animations. This is because real-life systems (including measuring equipment) have a specific frequency response (and often a different one for each individual frequency). Specifically in electronics, sufficiently high frequencies won't make it through a system (often because the physics of the system can't keep up with the rate of change). It is these high frequency components in a Fourier Series that enable signal to have sharp corners (rapid non-gradual changes). That is what makes an ideal square or saw-tooth wave (or essentially anything with sharp corners on a time-graph) impossible to exist/survive in a real-life (electronics) system. It is not just that the Fourier Series and Transform are useful tools, it is also the relationship between transient signals and their frequency components that determines how they will propagate through real-life systems. While I took electronics as an example, there are plenty of other systems for which the same principle hold.

Concept of Fourier transform (not necessarily all the math) is something that should be way sooner and more widely. Understanding it for a first time was for me a beautiful mind-bending journey.

I read how Fourier did the is initial work . Pretty amazing with all the data came to on paper and from there he developed the transform

Speaking of JPEG, radio engineers figured out that BW TV had a lot of unused bandwidth between the harmonic peaks. (3.57959... MHz and phase shift color info, along with the R-Y, G-Y, and B-Y...allowed the BW TVs to see either BW or colorized BW.)

My absolute favorite mathematics from college to solve complex audio and radio frequency problems. We did it by hand no computer used.

Just wow 😱😱😱 I was searching for past few months now on how integration of function multiplied with exponential will give the Fourier series. Thank you so much ma'am 👏👏

I learned about all the mathematics behind that in university, did some manual calculation and also software implementation back then but never had to do it myself afterwards (thanks to people who did the implementation in places where I could just use it). It was cool to revisit this after... OVER 15 YEARS???? 😱

Very good the way it mixed up the intuitive and simple explanation about the matter with the maths jargoons and formalism. Connected different subjects and captured the hole picture in awesome way. Really congrats

I have worked with an spectrum analyzer arduino code library before. I now understand why the algorithm is multiplying data to a series of numbers which seems correspond to a sine wave. Very good video! Keep it up! Thank you 😊

Oh man I used this transform in my mass spectrometry research. I had to program it because I can't math that. We built a dual ion gate that alternated gates opening with a voltage and we could block ions of various drift times and calculate the cross section surface area of proteins in various confirmations. I like to adhere various species to the surface of the protein probing it's external amino acids.

I love you so much! The way you explain things is breathtaking! You take complicated topics and explain them so easily with simple words - Richard Feynman would be proud of you, that's for sure! Myself, I want to thank you. You help me understand a lot of things that I will be needing/need for my studies. And it's so much fun to watch your videos!
