Ludvig Faddeev (1934 – 2017)

I saw from a friend's Facebook post that Ludvig Faddeev, known to me for his eponymous equations, died a couple of days ago.

Faddeev was a mathematician and physicist whose work is of great importance in few-body nuclear physics.  In particular, he developed a method for solving the quantum three-body problem that can be used when studying, e.g the triton or 3He, but also weakly-bound nuclei in which there is 2-neutron halo along with a strongly-bound core, such as 11Li. 

At this point I have to confess that I have never tried solving the Faddeev equation myself, though this blog post is tempting me to do so.  If someone reading would like to write a quick primer, then I'd be more than happy to post it here.
