Physics Book Big Ideas Simply Explained And Perceptions Of A Renegade Mind By David Icke Thomas Booth by Thomas Booth 978–1–4654–9102–2 instant download after payment.

Full Working copy of DK Physics Book Big Ideas Simply Explained from Pages 1 to 336
but someone attached a full copy of a different book,
Perceptions of a Renegade Mind by David Icke
onto the end from Pages 337 thru to 850 in an attempt to get it a wider audience
See Wikipedia entry on David Icke at https://en.wikipedia.org/wiki/David_Icke
Many would regard his ideas as conspiracy theory and on the fringe, but they are valid to a certain audience.
Quality copy of both books is excellent especially the smaller filesize of the DK book (10MB) compared to the other copies that are 100MB+
Ideally if someone has the software I'd split the book into two separate books and repost both as the quality is great, but David Icke would only appeal to a niche audience but should have a right to publish in the interest of free speech for all and inclusiveness of all options.  Just not everybody's cup of tea!!!...
Hope this helps... :)))
PS Keep up all the Good work at the Library
