OH:
"Bis ich da lange bei #Wolfram rumklicke, zieh ich mir lieber den #Bronstein ausm Regal."

"Es heißt #Bronschtein, sch, nicht EssTee!"

"Leck mich... #Bronstein!"

🤣😂

This is what 2 EUR and 10 EUR, respectively, get you on Amazon's used book section:
A manual of #chemical substances, which should be useful with my OHS studies.
And a #mathematics handbook that complements my good old #Bronstein handbook. The CD is still with it, by the way.

They fit right in with my #HarriDeutsch collection that I started around 1998 in university. 😊
