These are websites I found bookmarked on my mom's old laptop.  Hope they help:

• Ancient Egyptian Math Problems
  
• Computer History Museum
• Counting Board Abacus
  
• History of the World in 100 Objects
• Illustrated History of Computers
• NOVA - Ancient Computer
• NOVA - Time Travel

I also found these books and papers scattered around her bed.  They are way over my head:

• A "Complex" Theory of Consciousness
• Black holes and time warps: Einstein's outrageous legacy 
  
• The relation between quantum mechanics and higher brain functions: Lessons from quantum computation and neurobiology
