I find it funny the youtube's arm race for Jonathan blow clips

[@gtgunar]

Well it tookm something as great as geometric algebra for John to say something positive. Not gonna lie it has worth the wait.

[@4.0.4]

I think Jon isn't a very good teacher, but that's probably just because he's doing it impromptu and thinking while he goes.

Jonathan Blow explains Instant Radiosity algorythm.

[@Roxor128]

Little mistake near the end there: the i, j, and k of Quaternions are not equivalent to e1, e2 and e3, but to e12, e13 and e23. It's a scalar plus a bivector, not a scalar and a vector.

[@Matt23488]

I didn't even know geometric algebra was a thing until just now.

[@user-lz1yb6qk3f]

It's all great but quaternions i j k are equivalent to e12 e23 e31 basis bivectors not basis vectors like you have wrote

[@Contemplative05]

Thanks Blow for supplementing my vector calculus course learning lol

[@APaleDot]

Jon Blow knows geometric algebra? based.

[@APaleDot]

Which stream is this from?

[@sudgylacmoe]

As the resident "RUclips geometric algebra guy", while I'm glad it's getting more coverage, this video sadly does what many people (including me at first) do: present the geometric product only between two vectors purely algebraically, providing no geometric intuition or applications. I tried to rectify this somewhat in my addendum to the swift introduction, but it seems the damage has already been done, and there are still way more people that watch just the swift introduction and not the addendum.

[@PRIMARYATIAS]

Eric Lengyel just released a new book about Geometric Algebra. Just saying... maybe people here would like to checkout.

[@KilgoreTroutAsf]

I misread "Jonathan Blow explains algebraic geometry" and chuckled for a moment

Could we have the link for the full discussion? stream | vod

[@coAdjointTom]

For many moons I've been wondering if Jon/Casey etc. were aware of Geometric algebra

[@antronixful]

A little correction: Maxwell originally formulated electrodynamics using quaternions. Then it got replaced by the cringe vector calculus we all use in physics. Also, the reformulations using different algebras is something used in modern physics to tackle different problems. For example, there are many reformulations of general relativity using other algebras (including geometric algebra sometimes), because is easier to adopt other terms that might be overview using the classical formulation, like the torsion terms and even electromagnetic terms (in a spacetime equation).

[@xyzg34]

What stream is this taken from? Is it all about math?

[@Wiipodicus]

this rocks

[@tempname8263]

Aww, you got it kinda wrong.
