A
very, very short explanation of when it all happened
OVERVIEW
This comprehensive review of the past from the Big
Bang 13.7 billion years ago to today, covers:
- Physical history of
the cosmos
- Biological history
of life
- Cultural history of
humans
All three are intimately connected. Humans affect the biology and climate
of the world such as through the spread of agriculture and industrialization.
Ice Ages and asteroids hitting the earth strongly affect biology (e.g. the end
of dinosaurs).
Chapter 1 covers the brief period when the cosmos started.
Each chapter thereafter covers a period 3 times as long as the next
chapter. Thus the second chapter covers the period from 13.7 billion years ago
(Gya) to 4.56 Gya. The third chapter covers from 4.56 Gya to 1.5 Gya, and so on
to 1910. The last 3 chapters cover
the immediate past, followed by an epilog about the future and a postscript on open issues.
The
Chapters are further grouped into major
topics:
-
Physical
-
Biological
-
Pre
Human
-
Oral
History
-
Recorded
History
-
Modern
This approach of using factors of 3 allows the whole 13.7 billion years to
be covered in 22 chapters, placing emphasis on what is most meaningful to us.
Changes are slowest in physics, faster in biology and fastest in culture.
