Knowledge

Notes on the things I find worth understanding, grouped into a dozen areas. Each one has a frontier, and where that frontier runs out is where the Unsolved section takes over.

• Space — black holes, exoplanets, the James Webb telescope, the search for life
• Oceans and deep sea — deep-sea creatures, shipwrecks, marine tech
• Future technology — AI, robotics, quantum, fusion, brain interfaces, nanotech
• Mind and beyond — telepathy, telekinesis, teleportation, psychology
• Maths and science — relativity, quantum theory, fractals, DNA
• Philosophy and philanthropy — thinking clearly, and doing some good
• Ancient civilizations — lost cities, old engineering, open mysteries
• Inventions — the handful of ideas that reshaped everything
• Engineering wonders — bridges, towers, spacecraft, big projects
• Natural wonders — volcanoes, mountains, caves, weather
• Medical science — the body, genetics, the big breakthroughs
