Hi,

Disclaimer: I don't know what I am talking
about. But I like the vibe behind connecting
topics. So here we go:

How it started:

Gabriels Horn
Gabriel's horn, also called Torricelli's trumpet,
is the surface of revolution of the function y=1/x
about the x-axis for x>=1. It has infinite
surface area but finite volume.

How its going:

FINITE TIME BLOWUP FOR NAVIER–STOKES
or every positive viscosity, we construct a solution
of the three-dimensional incompressible Navier–Stokes
equations that starts from rest and develops unbounded
velocity in finite time while maintaining uniformly
bounded kinetic energy

Hava Fun everbody!

Bye
