Astronomy Winter School 2021
I have been giving an online lecture series on Cosmic Particle Acceleration at the Taiwan Astronomy Winter School on High Energy Astrophysics (see http://phys.cts.nthu.edu.tw/actnews/content.php?Sn=505 ) – a really nice experience during German Covid19 lockdown…and a very inspiring and well organized school…. the hybrid format allowed a large number of people from across the globe to attend.
