Einstein became a full professor at the German Charles-Ferdinand University in Prague in April 1911, accepting Austrian citizenship in the Austro-Hungarian Empire to do so.[79][80] During his Prague stay, he wrote 11 scientific works, five of them on radiation mathematics and on the quantum theory of solids.	./cache/en-wikipedia-org-9012.html	./txt/en-wikipedia-org-9012.txt
