Déluge
Brok3n Engines
Let us make the World’s largest catamaran. We will join two submarines, side-by-side, with steel girders. We will connect them with Cat6 cables, and hack the nav software to make them swim side-by-side. Our dogs will live in the left submarine, and our cats in the right, until we decide to switch. Then we will sail around the world and visit the tops of all the seamounts. (Skipping active volcanoes, of course.) Our WiFi password will be 2NotYe110w, but we may still sometimes listen to Beatles songs. Après le déluge we will make our pilgrimage to drowned Fuji-san. Then we will visit Banff and see the Rockies again. Perhaps some of the campgrounds will still be open. We will check them out in stereo through our periscopes. If any mountaintop still rises above the waves, we will camp on the beach and surf. Lake Louise will be gone, alas. The Athabasca Glacier, as well. You win some, you lose some. Doves and hawks, crows and vultures will we succour. Dulce et decorum est vivere.
Cover
The cover image is a phase portrait of
\(\begin{align*}
f(z)&=\frac{1}{z-f_0}\sqrt{\frac{e_2-z}{e_1-z}}\sqrt{\frac{e_4-z}{e_3-z}}\\
e_1&=-1-0.3i\\
e_2&=1-0.3i\\
e_3&=-1+0.3i\\
e_4&=1+0.3i\\
f_0&=-2
\end{align*}\)
The portrait is rotated 60°.
A phase portrait is a visualization of a complex function introduced by Elias Wegert in Visual Complex Functions: An Introduction with Phase Portraits. If you don’t see the equations or see only some strange code-like stuff, it may be a problem with your eReader. In this case your simplest solution is the PDF format or to read the story on substack.
