2 10….PRINTING PRESS The printing press made it possible to possible for the mass spread of books. The printing press was an agent of change because it made the mass production of books possible – circulating information and ideas farther than anyone at the time could have imagined. The printing press was invented by Johannes Gutenberg in the 15 th century. 1. Summary 2.3.8.9.7.6.5. 4. 10.

3 9. Refrigeration What and why: Refrigerators have significantly impacted the availability and storage of food, prolonging the storage of foods, especially fresh food. This increases our breadth for food choices, our diets, and our eating habits. When: The early 20 th century. Chemical refrigerants became widespread in the 1920s.

4 IEOR 190G: Patent Engineering 8. First Commercial Lightbulb @ 2015 ERIC QUACH. All rights reserved. 4 Thomas Edison 1879 Lightbulb transmit electricity through a wire with high resistance. Patent filed for light bulb categorized as “a carbon filament or strip coiled and connected to platina contact wires”. Paved way for infrastructure that provided electricity to every house and business. Today there are several choices of light bulbs available, from incandescent to fluorescent to LED.

5 Steam Engine  First patented by Jerónimo de Ayanz y Beaumont in 1606.  Popularized with introduction of rotary motion by James Watt in 1781.  Spurred Industrial Revolution, leading to massive increases in productivity.  Leads to global population and resource consumption explosion of the 19 th and 20 th centuries.  Supplanted by the Internal Combustion Engine and Electric Motor for rotary power generation in early and mid 20 th century.

8 4. Personal Computer An modification to mainframes and microcomputers that allowed these computational devices to enter family and individual use. Improved data storage, processing, and transmission capabilities, bringing more power and convenience to individuals. Almost ubiquitous in developed nations, with many variants (e.g. smartphones, tablets) becoming popular in developing nations as well.

10 2. MOBILE PHONES In the past decade, mobile phones have rapidly changed today’s society. Mobile phones made information and communication even more accessible, and changed rapidly changed society and economic structures. Now, many companies are built around mobile devices – such as mobile applications. Cell phones have also shaped the nature of relationships and the way people relate to one another. They have also influenced journalism, child development, and many other aspects of life. Mobile phones were invented by the Bell Laboratories in 1946. 1. Summary 2.3. 8. 9.7.6.5.4.10.

11 1. The Internet Connects billions of users worldwide (social networking and emails), starts public movements and campaigns Allows access to articles, videos, research papers, music, and more! Allows sharing of data between friends over long distances, allows expanded search for job opportunities Many businesses are based solely upon the Internet May purchase services or items online, may advertise store sales Theglobeandmail.com
