Course Description:



We begin with a look at trends in technology from a historical perspective and proceed from early development through to present day including a look at where technology is headed. Key areas of technologies that we use in the technology program curriculum will be explored in more detail such as semiconductors, communications, computers, and lasers.

Video Descriptions:



Connections Volume 1: The Trigger Effect

Both the beginning and the end of the story are here. The end is our present dependence on complex technological networks illustrated by the NYC power blackouts. Life came almost to a standstill: support systems taken for granted failed. How did we become so helpless? Technology originated with the plow and agriculture. Each invention demands its own follow-up: once started, it is hard to stop. This segment ends in Kuwait, where society has leapt from ancient Egypt to the technology of today in 30 years.

Connections Volume 2: Death in the Morning

How did a test of goldís purity revolutionize the world 2500 years ago and lead to the atomic bomb? Standardizing precious metal in coins stimulated trade from Greece to Persia, causing the construction of a huge commercial center and library at Alexandria. This wealth of nautical knowledge aided navigators 14 centuries later. Mariners discovered that the compassís magnetized needle did not point directly north. Investigations into the nature of magnetism led to the discovery of electricity, radar and to the atomic bomb.

Connections Volume 6: Thunder in the Skies

A dramatically colder climate gripped Europe during the 13th century profoundly affecting the course of history for the next seven centuries. The changes in energy usage transformed architecture and forced the creation of new power sources. The coming of the Industrial Revolution, spurred on by advances in the steam engine, scarred England indelibly: but a moment in history later, gasoline-powered engines opened the way to the heavens.

Connections Volume 4: Faith in Numbers

Each development in the organization of systems (political, economic, mechanical, electronic) influences the next, by logic, by genius, by chance, or by utterly unforeseen events. The transition from the Middle ages to the Renaissance was influenced by the rise of commercialism, a sudden change in climate, famine and the Black Death, which set the stage for the invention of the printing press.

Connections Volume 5: The Wheel of Fortune

The power to see into the future with computers originally rested with priest-astronomers who knew the proper times to plant and harvest. The constellations influenced life spectacularly, particularly when the ailing Caliph of Baghdad was cured by an astrologer using Greek lore. His ancient medical secrets were translated and spread throughout Europe, ushering in an era of scientific inquiry. The need for more precise measuring devices in navigation gave rise to the pendulum clock, the telescope, forged steel and interchangeable machine parts-the basis of modern industrial system.
