Technology, Engineering, and ScienceTechnology is SocietyHistory of Technology

What is Technology?

� The word technology comes from the Greektechnología, an 'art', 'skill' or 'craft' and -logía, the study of something.

Science

� Science is the reasoned investigation or study of phenomena, aimed at discovering enduring principles among elements of the phenomenal world by employing formal techniques such as the scientific method .

Engineering

� Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often (but not always) using results and techniques from science.

Technology

Technology is often a consequence of science and engineering — although technology as a human activity precedes the two fields.

� Science might study the flow of electrons in electrical conductors.

� This new-found knowledge may then be used by engineers to create new tools and machines, such as semiconductors, computers,

Technology and Society

As technology changes, society changes� hunters and gatherers (stones) � simple agricultural (plow) � advanced agricultural (water wheel) � Industrial (industrial revolution) � Information (internet)

Invention vs. InnovationFirst of its kind

Modifications and changes to the first

Continuous changes and improvements

Paleolithic (2.5 million –10,000 BC) STONE AGE

� The earliest stone tools were crude, being little more than a fractured rock.

� Tool use remained relatively unchanged for most of early human history.

Neolithic through Classical Antiquity (10,000BC – 300AD)COPPER / BRONZE / IRON AGES

� Advances in agriculture, tools, and energy.

Medieval Technology

� Medieval technology saw the use of simple machines, such as the wheelbarrow, windmills and clocks.

Renaissance Technology

� The Renaissancebrought forth many of these innovations, including the printing press

Early Machines

Early Flight

Trebuchet

Industrial Revolution

� A period of great technological discovery, particularly in the areas of agriculture, manufacturing, mining, metallurgy and transport, driven by the discovery of steam power.

� Technology later took another step with the harnessing of electricity to create such innovations as the electric motor, light bulband countless others

Modern Technology –20th Century

� In physics, the discovery of nuclear fission has led to both nuclear weapons and nuclear energy.

Modern Technology –20th Century

� Computers were also invented later miniaturized with transistors and integrated circuits, with the creation of the Internetresulting after.

Positive and Negative Impacts

Cell Phone: Ability to speak from any location

Using phone at movies!Upsetting to others!!

Talking while driving!Dangerous!!

Texting or talking on the Phone, ignoring the people around you!Rude!!

Technological Ethics

� Ethics: Having to do with right and wrong.� Advances in technology have created

Ethical dilemmas.

Cloning a sheep

May lead to…

Cloning humans

Altering DNA

THEN WHAT!

May lead to

Unexpected mutations

Technology vs. Science Fiction

� Science fiction is a genre of fictiondealing with the impact of imagined innovations in science or technology.

� Often dealing with the fears of new and unexplored technologies.
