    That is why math is wrongly hated. More than 25 years back, when I was a student, not even one teacher bothered to take 10 minutes to break down this formula to us.

      Respectfully, I would wager a guess that the sequence in which you learned the necessary parts simply connected these same dots much more slowly. For example, if you took a person with only a rudimentary knowledge of arithmetic and tried to show them this, they would (rightfully) struggle greatly. There are a mountain of foundational concepts which build up to this. It is an unquestionably elegant result - as are almost all great theories. Relatively, quantum probability, etc. can each be summed up on a single page - but take years to fully grasp. You just happen to be at the point in your journey where a Taylor expansion, derivatives, exponentials, imaginary numbers, etc. aren't like a new language - and good on you for that!
      Lots of talented educators have sought a path around that and there are good reasons that no one has really found a better way yet. (We will likely agree that there are better and worse teachers!)
      Cheers!

    That equation always blows my mind. How can two transcendental numbers and an imaginary number combine to form an integer? Euler was a genius and my favorite mathematician.

      The universe is indeed mysterious. Also, think about how the circumference of a circle can never be an integer despite the possibility of an integer diameter, and yet the shape looks so complete. Let's not even go into all the crazy behavior of conics.

    I woke up in the middle of the night and couldn't get back to sleep. So, as usual, I began learning something new in mathematics. I find this time to be very productive in terms of absorbing new concepts. I came across this video and got curious. I am just a math enthusiast who is now retired and spends a fair bit of time catching up on mathematics. This made me truly understand why Euler is considered the greatest mathematician who ever lived. You made me appreciate the real beauty of Euler's formula. It felt like a detective story as I tried to stay ahead of you and guess what would come next. It was so much fun! You were quick, but I had no problem following along. Now, I kick myself for not pursuing this path earlier. At 67, it's not too late-at least for having some fun with mathematics. Keep up the great work, and thank you for taking me on this wonderful journey.

    If we make the square root of negative one or i, the imaginary unit, the field that represents the reference frame taking the measurement and place it above the stress energy tensor in Einstein’s field equations (Ruv - 1/2Rguv = 8piG) instead of an expectation value (^) of a probability distribution (from quantum mechanics), doesn’t that solve the measurement problem and quantize the time? The field, which could be called the time, measurement, conscious, or tachyonic field interchangeably is quantized by the reference frame taking the measurement and consciousness and those that have it becomes the metric the universe uses to measure or experience the time. Consciousness is the non-local universe and also the non-local hidden variable or “spooky action at a distance” that is collapsing the wave function of the energy system it is observing. Is this not the only way Einstein’s theories of relativity, quantum field theory based on the standard model of particle physics, evolution by natural selection, and Gödel’s incompleteness theorem can work and be compatible with each other? It is not a theory of everything but a step that has to be taken to understand ourselves better. The act of measurement is the same thing as the universe measuring itself. The tachyon, consciousness, and the imaginary unit all appear to have the same characteristics and relativity becomes the fundamental piece of quantum field theory being the quantization of this field, or time. The reference frame taking the measurement is simultaneously in the past, can anticipate the future, and take measurements in the present to take the time. It is not only there simultaneously but before anything that is moving through spacetime, including photons, making it faster than the speed of light. If you also look at the ‘beginning’ when all of the energy and time in the universe was condensed to a single reference frame, that is where the entanglement of all things happen, and this non-local reference frame (before time) measures itself to create the time. For a tachyon to measure itself or slow down to the speed of light, it would require an infinite amount of energy to do so, creating conditions similar to what we think of as the Big Bang. If this was the case, then everything (all energy) would fall under one wavefunction. Perhaps Euler’s Identity represents a moment in time (e^ipi + 1 =0) that can be derived from Einstein’s field equations through the imaginary unit i. Consciousness would then be something that does not emerge from spacetime but fundamental to it. Gravity becomes the curvature of this particle or energy, which we will call the tachyon, measuring itself and consciousness (the reference frames that have it) becomes the metric that the universe uses to measure or perceive the time. Simply there is no time without consciousness. Even if consciousness was emergent from spacetime, what configuration of particles, made of unconscious ingredients, creates a conscious one? Even if you figured out that a specific configuration of particles creates a conscious experience, how would you be able to verify that? You would have to be the experience itself, no? This relates to Gödel’s incompleteness theorem in which the fundamental truth can only be experienced not described by words or numbers. That which cannot be described by words or numbers is fundamental, it is assumed. Consciousness is fundamental. If consciousness is emergent, how did the universe know to assemble itself together in a specific structure that would inevitably lead to a conscious experience? What is the probability of that? That has to be zero, correct? How can the universe and spacetime work any other way if these theories are correct? The question I have is does this field choose which perspective of itself it wants to experience or is it random?

    • @DavidAKZ

    Will wait for the Fourier video but I noticed that in this video one counter-intuitive thing is explained via other (possibly even more) counter-intuitive thing because Taylor’s series are good for calculating value of functions with some degree of precision but it completely doesn’t explain what ratio of triangle’s sides has to do with adding powers divided by factorials, so that still looks like magic.
    In other words, there is still question, what comes first: powers of i or rotation of the θ. I think geometry comes first.

    Question I have is how many possible proofs of Euler's equation are there? My engineers gut tells me they will be few and far between and will likely map to and look similar to the Taylor series above, even if they are from out of another branch of mathematics. It aint calculus but there ain't no substitute for intuition as it sure sounds to me like Euler himself just found it just through fiddling and intuition!

    I understand this video and the previous one too, but why is e used so ubiquitously in other equations where we need an exponential, but are not concerned about oscillatory behaviour or the rate of change of the exponent?
    For example, in semiconductor physics, we can equate the carrier concentration at one point in space to another point in space by e^(the potential difference / thermal voltage). If carrier concentration is exponentially dependent upon potential, why does the exponent need to be e, and not any other constant like 2 or 3?

    Great video. Could you explain how the Taylor series was derived.

    Sir can you pls ans my qn ... If we calculate the divergence of vector r/r³ then it's zero ..but if we draw then we will see that there are outward facing vector fields present and where divergence can't be zero... Pls tell me if you can.. or make a video

    could you make a video about taylor series? where do they come from? your explanations are amazing and very easy to understand
