They&#x27;ve been used elsewhere in physics for ages: well before geometric algebra in its current form was developed. (I first encountered them in the Petrov classification of spacetime structures.) So it&#x27;s a bit awkward to see &quot;bivector.net&quot; as a label for geometric algebra resources. (And they&#x27;re not alone: the Wikipedia article on bivectors reads as if geometric algebra is the only context where bivectors are meaningful, too.) In fact, I&#x27;ve recently written a paper[]…</p><p><a href="https://hackerpaper.kaipfister.de/p/2207.03560/">Paper and discussion history</a>. A mention is not an endorsement.</p>physics.ed-ph
