Knowing Jeffrey for the past months has been quite a whirlwind of mind-bending experiences, ranging from politics and contemporary history to the nature of infinity to neural nets to international law — and to jazz, with Jeffrey joining in Valeria's patient efforts to introduce me to a musical genre I'd known nothing about.
