Reality is Not What It Seems

The Journey to Quantum Gravity

Carlo Rovelli 2017 . Cedar Mill 503.143


Idea is that spacetime is quantized, connection graphs between nodes at Planck scale. "Big bang" is "big bounce"

  • p059 Maxwell's equations: dF = 0, d*F = J (?? divergence and curl of "field" ?? )
  • p157 John Wheeler audio

  • p182 "time does not exist" at the Planck scale, time is relational at large scale
  • p220 Possible loop quantum gravity prediction of background radiation spectrum


Seven Brief Lessons on Physics

Hillsboro 530 Rovelli 2016


Quick fluff ... page 48 shows "bounce" from prior phase. Would that bounce homogenize the universe ... instead of inflation?


There Are Places in the World Where Rules Are Less Important Than Kindness

West Slope Library 500 Rovelli 2018


Sorta interesting essays, literary mostly

  • Aristotle the Scientist; not as wrong as Galileo's attacks. Light objects do fall slower ... in air

  • Vladimir Nabokov, Lolita and lepedopterist
  • Newton's alchemy - notes but not publication. Not secrets, instead nothing found convincing
  • Copernicus / 1977 youth movement / Brecht Galileo / Dante universe model / Statistical Outliers
  • Bruno de Finetti subjective probability

  • Does Science Need Philosophy? dismissing philosophy is not science, but philosophy

  • Other Minds (Octopus)

  • Chandrasekhar, hard work more important than intelligence
  • When Einstein learned of his errors, he changed his mind
  • Archimedes "The Sand Reckoner", method to express very large numbers (largest named number was myriad, 10,000
  • Inequality, Rousseau / Ancient Wars / Politics / National Identity / Darwin / Curie
  • Lemaître ... cosmology closest to religion
  • Giacomo Leopardi wrote History of Astronomy age 15, poet

  • Lucretius De rerum natura | David Lewis, plurality of worlds

  • Naturalism | Nāgārjuna

  • Mein Kampf - fear of being weak

  • Black Holes: Einstein and Schwarzchild / Hawking and Heat / Collapse (and time dilated quantum rebound?)
  • Kip Thorne and gravitational waves | Hawking radiation | Roger Penrose | Baby Jesus and presents; peace instead?
  • Global Warming | Churchill and Science | Infinite Divisibility of Space, Zeno's (false) paradox
  • Ramon Llull | Are We Free? (we don't know how to know)

  • LSD | Why I am an Atheist (mystery is) | Hadza people

  • A Day in Africa | The Festive Season is Over | This Short Life Feels Beautiful To Us ( COVID )
