Automobiles, Airplanes, Mass Production, and Assembly-Line Progress
- This was largely due to the adoption by industry of the technique of mass production, the system under which identical products were churned out quickly and inexpensively using assembly lines.
- Using the manufacturing assembly line system, in which individual parts or sets of pieces are added to a product at stations on a conveyor belt or other moveable line, entrepreneurs such as automobile tycoon Henry Ford were able to greatly increase productivity.
- Telephone lines were strung across the continent, and indoor plumbing and modern sewer systems were installed for the first time in many regions.

Eratosthenes' Experiment
- By Earth's gravity, the mass hung straight down; the line of the string established a "vertical" at that geographic location.
- To measure the angle of incident sunlight there Eratosthenes lowered a plumb bob suspended by a string deep into a well.

Aging and the Cardiovascular System

- As a result, Claudius was declared Emperor by the Praetorian Guard after Caligula’s assassination due to his position as the last man in the Julio-Claudian line.

Survival Needs
- While the development of tools, plumbing systems and food preservation have enabled modern man to live life with many creature comforts, the truth remains that the requirements for human survival are quite basic.

Iron Oxidation
- In the process, the bacteria produce a brown slime that builds up on well screens, pipes, and plumbing fixtures.
