Legends suggest each book covered a different field of advanced knowledge:

1. Psychology & Mass Influence – Understanding human behavior
2. Physiology – The limits of the human body
3. Microbiology – Life, bacteria, and disease
4. Alchemy – Transformation of matter (early chemistry ideas)
5. Communication – Advanced forms of language and signals
6. Gravity – Understanding forces of nature
7. Cosmology – Space, planets, and the universe
8. Light & Energy – Sources of power

These subjects were far ahead of their time, which is why they were allegedly kept secret.
