I am a software engineer at a rocket company. There was a bug discovered in the code having to deal with interpreting rocket orientation in some simulation code originating from a mistake in the quaternion math. Despite having a physics degree, I was not at all familiar with quaternions so I turned to the internet for guidance. Your videos on quaternions helped me understand them enough to discover the mathematics mistakes and derive the correct formulae. Just thought you'd like to know this video helped launch rockets :)

I don't say this lightly: Your videos and especially these interactive videos will pioneer the future of education. I'm often disappointed in our school system ( here in germany but probably applies for other countries as well). Schools don't use the potential of modern media thereby being inefficent and wasting the stundent's time and undermine their curiousity. As a teacher I try to work against that but get caught in the same fatigue rather often. But being confronted with new topics this way I become like a child again in the best sense : I'm curious and full of wonder. And it's fun to learn something new. I have regained hope that school can be like that most of the time for future generations of students.

I just did the interactive thing and I feel genuinely enlightened lol. As a hobby gamedev, quaternions have probably been the topic I've avoided most. Like all other topics I feel like I've been able to at least learn something about, but quaternions have always escaped me. I left it to "confusing computer math stuff I can't understand" and just used the functions that convert to and from euler angles. I saw another one of your videos, possibly a livestream, where my mind was blown by the simplicity of using cos(x) + i*sin(x) to represent 2d rotation, but seeing it apply to quaternions, where i just gets replaced with an axis for it to work in 3d is even more mind-blowing. I feel like I actually understand quaternions now, even enough to actually use them too. I cannot express the shear amount of confusion I went through trying to learn about them at first before giving up. This is the by far the best explaination and especially visualization ive seen for them! Awesome work!

@haniyasu82366 жыл бұрын
Well, no, physics almost never concerns itself with specific orientations and so almost never needs quaternions specifically (just like it basically never uses rotation matrices), but when putting the ideas of physics into a computer, they *do* become important and very much help tremendously (just like they do in animation) Furthermore, there are a fair bit of quantities that make a *significant* amount more sense if you think of them using Geometric algebra instead of classic vector algebra. For instance, angular velocity and momentum both are usually done as single numbers when in 2D but somehow magically become vectors in 3D, and while usually not relevant, this system has no good way of being extended into 4 or higher dimensions. However, if you instead think of them as quantities in a _planar_ direction and represent them as Bivectors, it all makes so much more sense. Angular momentum is a "scalar" in 2D, because there is _only_ planar direction, and so all angular momentums must be scalar multiples of that one plane; and it's a "vector" in 3D because every plane (and thus bivector) can be represented as its normal vector. In fact, this even makes angular momentum in 4D make sense (once you look at the math) and even explains some of the really weird results there (like how you can have two completely independent rotations happening at the same time).
@abhimanyupallavisudhir60076 жыл бұрын
@Anvil What you're saying about bivectors is correct, but the formalism of *geometric algebra* in particular is not the best way to understand them -- the right formalism is tensor algebra (which is indeed exactly how you represent rotational things like angular momentum and cross products in real physics), where "bivectors" are just antisymmetric rank-2 tensors. As for two independent rotations happening at the same time, I don't think anybody regards that as particularly weird and unintuitive. You have four dimensions, each rotation only affects two of them. Of course you can do two at once -- it's just like how you can do two scalings at once in R2, for instance.
@haniyasu82366 жыл бұрын
@Abhimanyu Pallavi Sudhir Yes, I am aware that geometric algebra (or rather Clifford algebra) is just a tensor algebra where the square of a vector is a particular quadratic form. Additionally, I'd definitely agree with you that Geometric algebra is not the end all be all of math and physics. Hell, it can't even do general linear transformations. However, as a formalism, I really don't think it's much of a stretch to say that it makes some things more sense than the default 3D + cross product system, and honestly, it's way more intuitive than tensors. But of course, while I have found in my experience that GA makes things way simpler, there will always be things like moment of inertia that like to defy simplification. (Furthermore, full disclosure, I am definitely not a physicist. I tend to work with physics simulations in particular way more than doing theoretical and high level physics, so it very much may be that in your use case, tensors work significantly better) Also, yes, in hindsight the two rotations at once makes perfect sense, but it's one of those things that is surprising to someone who hasn't seen it before and has only worked with 2D and 3D using only the cross product and very little abstract formalism.

BTW - it just goes to show you that you don't necessarily need to know all there is to know to move forward in math, for example, I wrote the math library that includes quaternions and matrix multiplications, points vectors etc. that's at the core of both Maya and AutoCAD, both of which are exposed to 3rd party developers via the API, so if you made a call to such a function, then I wrote, named, designed etc. that code, you're calling. I've taught many folks about quaternions, but NEVER with the insight I've gained from your work Grant! Thank you!

When describing multiplication by complex numbers, I suddenly understood why you have to halve the angle you want to rotate by! It all makes sense when you consider what happens to an angle defined by the centre of a circle and two points on that circle when you replace the centre with another point on the perimeter!

Unrelated, but your 3d visualizations have gotten better! rewatched the essence of linear algebra series, and the 3d there was stuttery and had unsightly arrows. Very happy to see a creator self-improve

Finally, I can make heads and tails of this! Thank you!

I will exam on Analytical Mechanics tomorrow and getting stuck to make sense of the orientation of rigid body with quaternions! Thank you so much for the video! Really very helpful!

That's simply amazing: learning linear algebra and at the same time have the possibility to "touch" it...

What a great idea to make an even more intuitive way to understand complex things like quaternions! I have an exam on robotics and this was all very abstract for me. You're interactive video's really helped me get this topic on a whole new level. Thanks al lot!! Ps I'm always a big fan of you're video's to really understand the meaning of complex mathematics!

THANK YOU!!!!! I've been trying to figure out quaternions for a long time now. This demonstration really helped! Keep up the good work!

This is really exceptional! Explorable videos are the best educational tool I've ever seen so far in my life. And they are potentially perfect to use in many more topics. GREAT!!

That new intro mesmerized me

This seriously helped me understand the concept after I was drowning trying to visualize quaternions on my own.

I swear to god I've tried understanding quaternions 4 different times now I think. after watching this video for the 5th time IT JUST CLICKED! it makes so much sense, I was wondering if I really had to think in 4 dimensions but wow it can be thought of so much easier than that!

I went through the entire interactive video series, and I gotta say, if I could pause your ordinary youtube videos and mess around with the parameters currently being graphed on screen to better understand what the thing is I'm actually looking at, it would be spectacularly helpful.
