(MBM) • Feb 1 Introduction. Plans for the course. Placing the human in a geological context. (MBM) • Feb. 8 Introduction to basic physical concepts: force, work, angular momentum, energy and power. Units for measurements. (MBM) • Feb. 13 Introduction to mechanical systems. (FHA) • Feb. 15 Introduction to basic chemical concepts: atoms and molecules, oxidation and reduction, energetics of reactions, and properties of materials. (MBM)

  8. Lecture Schedule • Feb. 22 Work and energy in pre-industrial society: wind, water and animals. (FHA) • Feb. 27 Wood, the primary energy source for pre-industrial societies. Introduction to the carbon cycle – how solar energy is transformed to chemical energy in the form of biomass; how wood was used and how civilizations rose and fell depending on its supply. (MBM) • Mar. 1 The age of steam. Properties of water. The first steam engine, its operational properties, applications and short-comings. (MBM) • Mar. 6 The beginning of the industrial age and the mechanization of textile production. (FHA) • Mar. 8 The first textile factory in the US. The Waltham system and the development of Lowell – the first Industrial City in the US. (FHA)

  9. Lecture Schedule • Mar. 13 Watt’s perfect engine. (FHA + MBM) • Mar. 15 Mechanization of the steam engine - flywheels, gears, linkages, valves, and motive power for boats, railroad and the generation of electrical power. (FHA) Mar. 20 Midterm Exam • Mar. 22Emergence of coal as a primary fuel. The origin of coal, how it was used, and the associated environmental costs. (MBM) Spring Recess – March 25 ~ April 2 • Apr. 3 Coping with urbanization. The challenge to supply cities with clean water, disposal of sewage and to cope with disease. How these issues were addressed in some major cities. (FHA) • Apr. 5 Introduction to scientific principles underlying electricity and magnetism. (MBM)

  10. Lecture Schedule • Apr. 10 Technological applications of electricity: Morse, Edison, Tessla, and Westinghouse. (FHA) • Apr. 12 Electrical devices: telegraph, lights, motors and refrigeration. (FHA) • Apr. 17 Emergence of oil as a primary energy source. (MBM) • Apr. 19 The internal combustion engine: Otto, Diesel, Daimler and Ford. (FHA) • Apr. 24The airplane: from the Wright brothers to the 747. (FHA) • Apr. 26 Nuclear power. What is it? What are its problems and prospects? (FHA + MBM) • May 1 Manufacture of critical materials: iron, steel and cement. Chemical and energy considerations. (MBM) • May 3 Retrospective and prospective. (FHA + MBM)

  11. Earth Events • Earth forms from a spinning mass of gas and dust composing the original solar nebula: 4.6 billion yr BP • Differentiation into core, mantle, crust, ocean, atmosphere occurs soon thereafter

  16. Earth Events • Oldest preserved rocks show indicatives of simple prokaryotic life forms – bacteria and blue-green algae • More complex life forms, eukaryotes, develop 1.5 billion yr BP. Fusion of cells from pre-existing prokaryotes?

  17. Earth Events • A further billion years elapse before appearance of first multi-cellular animals – flat, pancake shaped, soft-bodies organisms named for a region in Australia when their fossils were first detected – the Ediacara fauna. • Profusion of life forms detected soon thereafter in the Burgess Shale, discovered by C.D. Walcott in the Canadian Rockies in 1909 • Vascular plants, 445 million yr BP • Life spreads from ocean to land, 440 million yr BP

  18. Earth Events • Amphibians, 300 million yr BP • Massive extinction, 225 million yr BP. As much as 96% of all existing life forms eliminated. • Mammals develop 160 million yr BP • Dinosaurs eliminated in second major extinction event 65 million yr BP • Homo erectus, 1.7 million yr BP • Homo sapiens, 150 thousand yr BP

  19. Earth Events • Migration of humans around globe, 50 thousand yr BP • First humans reach Americas, 20-30 thousand yr BP • Development of agriculture and domestication of animals, 10 thousand years ago in the Fertile Crescent – Jordan, Israel, Syria, Iraq, Turkey • Industrial Revolution, 250 years BP

  20. Earth Events 4.5 4 3 2 1 0 (billion yrs BP) • Burgess Shale • Eukaryotes • formation of Earth • Prokaryotic 5 4 3 2 1 0 (100 million yrs BP) • amphibians • mammals • Vascular plants • Life expands to land • extinction eliminates dinosaurs • mass extinction

  21. Earth Events 2 1 0 (million yrs BP) • homo erectus 200 150 100 50 0 (thousand yrs BP) • Homo sapiens • human migrates • Humans reach Americas

  22. Earth Events 30 20 10 0 (thousand yrs BP) • Humans arrivals in Americas • development of agriculture 1000 750 500 250 0 (yrs BP) • Industrial Revolution
