Saw Paul Francis lecture,during the school of Astro@Maq.Uni,this Aug.
The sound that blew me away most was the "big-bang"or should i say C.M.B.?Anyway,brilliant,as you really do get a feel for the difference between
young & old pulsars,(&stars)instantly.Love to hear sol too.
Especially during a C.M.E. or @ solarmax. peak.
cheers
