Jonathan Verner — Coloring metric spaces: A report from the oracle

“I will present a short and elegant argument, due to S. Shelah, showing how one can construct a metric space $X$ of size $2^\omega$ such that for any countable metric space $K$ and any countable coloring of $X$ there is a monochromatic scaled copy of $K$ in $X$”.
