Galaxy formation is a complex, hierarchical, highly non-linear
process, which involves gravitational collapse of dark matter and
baryons, supersonic, highly compressible and turbulent flows of
gas, star formation, stellar feedback, as well as...
We explicitly construct an extractor for two independent sources on
$n$ bits, each with min-entropy at least $\log^C n$ for a large
enough constant $C$. Our extractor outputs one bit and has error
$n^{-\Omega(1)}$. The best previous extractor, by...
