About This Design

Equilibrium Points Tie

Equilibrium Points Tie

Are those the behaviours of linearised two-dimensional systems of differential equations in the neighbourhood of an equilibrium point on your tie or are you just happy to see me? Ha! That joke just never gets old. Source, sprial, and saddle (the "three s's" as our diffy-q prof used to call them). Technically, there's five behaviours if you differentiate (zing!) between spiral-in and spiral-out and between sources and sinks (and more if you include trivial solutions) but that made the design kinda crowded and you couldn't make out the glyphozoids very well because they were so small. When strangers on the bus point this out, it will give you practice in the six most useful words in all of mathematics: "Meh, it's just a sign flip." Addendum: Some of you have noted that we omitted centres. Feel free to view these as spirals with zero real part if it makes you feel better. And, yes, we're assuming the determinant of the Jacobian is non-zero here. And the eigenvalues are distinct. Jeez, ya nerdz. IT'S A TIE NOT A DISSERTATION.

I originally ordered 1 tie to test and ensure I liked it with the suits we had ordered! The tie came and it was perfect! We loved it! The colours were bright and the tie was beautifully made. I then ordered the 6 additional ties and the colours are slightly different. The 6 ties were a little less vibrant and the white background was slightly different! .
