Before The Big Bang
Laura Mersini-Houghton 2022
523.1 MER Beaverton Library

Cosmology can be strange, Communist Albania was stranger. This book takes a strange path through both, but arrives at worthwhile insights. The book mixmasters time sequences like many modern books, I will try to unmix it here.
Biography
- xi Albania 3M people, before 1991 the "North Korea" of Europe
- xii mother's workplace had English books
- xiii economist father Nexhat Mersini (no citations or biography found) new algorithm for inverting very big sparse matrices
- 03-4 math or physics? did both
17 1991 Feb university student hunger strike, 100s of miners walked 50 miles to Tirana, overthrow government
- 19 170K-300K left via foreign embassies, almost all students
- 01 1991 Oct US Embassy opened, Cultural Center
- 35 Professor Bardulla, different solution to exam
- 01 1994 bachelor's degree physics, grad school elsewhere
- 01 1994 Jan, Tirana's Mother Teresa Airport to Fulbright Scholarship U Maryland, arrival paralyzing blizzard
- 05 200 physics grad students, 3 women
07 large bookstore in Bethesda ( Second Story Books?)
21 Masters degree at UMD, 1997-2000 UW-Milwaukee for PhD, Leonard Parker
- 50 1992 Met economist Jeff Houghton in Albania
- 51 1993 Dec meets LM at Zurich, flies to US with her
- 38 1994 Jan, UNC Chapel Hill
- 61 2000 Doctorate UW-Milwaukee, focus on cosmology
Philosophy of Science
- xix childlike curiosity endures, neoteny
- xx benefits/justification, Faraday's "you will tax it someday"
Cosmology
- xvii we are part of a multiverse, with cross-talk to other universise due to quantum entanglement, predicting observables
06 Penrose: universe likelihood less than 10(-101e123)
07 Hawking and Penrose singularity theorem 8-14 argument from entropy, big bang VERY ordered?
- 15 foreshadow wrong question, different explanation
25 1922 Alexander Friedmann expanding universe
26 Gamow hot big bang / 27 Helium-sized initial universe too big for uniformity
- 29 Universe not closed or open, geometrically flat
- 33 author believes cosmic inflation theory incomplete
62 standard model, universe expands to blueberry size, particle wavelength increases, energy decays into light and other particles, reheating (misnomer)
63 Big Bang Nucleosynthesis, helium and other elements, 4 minutes
63 380KY, photons decouple into Cosmic microwave background CMB
