A vital substance to our development as a civilization

Glass is silicon dioxide. It formed naturally out in a desert somehow long ago. It was found in King Tut’s tomb. Glass begets (or at least, enables) this series of events:

  1. Glass is beautiful → glass is valuable
  2. Glass is valuable → Glassmaking becomes popular
  3. Glassmaking is dangerous → glassmakers are concentrated together
  4. Glassmaker concentration → glass innovations
  5. Glass innovations → clearer glass
  6. (unrelated: Johannes Gutenberg’s printing press is invented) → people realize they’re all far-sighted
  7. People have reason to correct far-sightedness + glass innovations → glasses are invented
  8. Glasses are invented → Microscopes & telescopes are invented
  9. Microscopes and telescopes increase human capacity for knowledge acquisition → further human understanding of sciences
  10. Glass + Metallurgy → mirrors are invented
  11. Mirrors become popular → people develop a sense of self unlike they had before
  12. Mirrors enable the invention of “perspective” art

— glass as a tool —

  1. Glass strands are found to be incredibly strong → fiberglass is created
  2. Ultra-clear glass + glass strands → Fiber-optic cables are possible & transcontinental internet is possible
