Thanks, but wikipedia_en_all_nopic_2023-12.zim is still 56 GB, whereas the BZ2-compressed Wiki2Touch archives are only about 14 GB for the latest (and only 8 GB for an archive from 2012 which I'm using).
I think a great caution should be used with modern physics and chemistry - it may be a way to get yourself killed for sorcery.
But if you want to say alive then I'll recommend including few books about creating modern medicine from scratch - like creating aspirin from willow bark and penicillin from molded bread.
