bofh: note that we use operator* for the application of a bivector to a vector, because they're morally just matrices
<egg>
so we use * for the cross product in a way :-p
<egg>
(but for the inner product we use InnerProduct, because that's *not* composition/multiplication, unless you identify a vector with the corresponding linear form)
<bofh>
oh I assume we're not working in a Hilbert space?
<egg>
bofh: we are tbh
<egg>
bofh: it's just that I find it morally wrong to write the inner product like matrix multiplication
<egg>
whereas it is natural to do so for the "cross product" between a bivector and a vector
<bofh>
oh in that case just (ab)use Riesz Representation to view it as vector-vector multiplication of a vector with the dual of another vector
<egg>
(between vectors, yielding a bivector, it is Wedge, not * of course)
<bofh>
okay good
<egg>
bofh: which means that the above formula is just a classic computation of angular acceleration

egg: so why is it called the portmanteau theorem? Does it pack two theorems into one?
<soundnfury>
("When _I_ state a theorem", said the egg, "it proves precisely what I want it to prove - nothing more, nothing less.")
<egg>
soundnfury: apparently it's not known why it bears this name
<egg>
also I didn't know the name, because I haven't learned stats in french
<soundnfury>
also, google translates porte-manteau as "coathanger", which makes me sad
<soundnfury>
because portmanteau is a loanword, which is a calque, which is a loanword.
<egg>
soundnfury: yes, it's pretty transparent, it's coat-bearer (or a coat-wearer or a coat-holder or something, porter translates to many things)
<soundnfury>
yes but a porte-manteau is a kind of luggage or valise. A coathanger is a bit of bent metal. These are not the same concept.
<egg>
soundnfury: nono, it's not luggage, it's a coat rack
<egg>
soundnfury: and the bit of bent metal is a cintre
<soundnfury>
egg: ok, in that case we mangled it when we stole it
<soundnfury>
because in English, the meaning of "portmanteau" is (at least according to Wiktionary) "A large travelling case usually made of leather, and opening into two equal sections"
<egg>
soundnfury: clearly that's because you needed to get away quickly when you stole the word; a coat rack would have been too cumbersome
