Industrial Revolution
1870-1900) • Period of time when the face of industry changed dramatically. • Lasting impact on the economies of the world and the lives of the person. Introduction of inventions that made the life of people easier.
Lab-on-a-chip
A number of researchers are currently working to develop what they call a "lab-on-a-chip." - These small devices will be able to take one of your body fluids (like blood or saliva) and analyze it to determine whether you are likely to develop specific diseases or health conditions, without ever visiting a doctor. - One way this might work is that every day at breakfast you would breathe into a straw and the chip would see if your susceptibility for any problems or exposures to dangerous chemicals has increased. - Such daily monitoring might help to find future conditions very early and perhaps make treatments more successful. - Some of these devices are currently available, but scientists are working to make even smaller designs that can screen for many more diseases with a faster response time.

Systems (lab on a chip)
- The chip won't work by itself—it will have to be patched into a computer that can process the data. - Someone, most likely a corporation in this case, will have to build a database that can translate the data into a usable form. - And ultimately, the lab-on-a-chip does not do much good unless there is a medical system that can cure the disease, alleviate the symptoms, or address the problem. - How do we want this data to be used and distributed?
Values shape how technologies are both developed and adopted
- Values also shape what scientists and engineers do. - A combination of different values can motivate people to become scientists and engineers. - They may do it because they find it fun. - They may do it because they think they can make a lot of money at it. - And they may do it because they hope to make the world a better place through innovation. - Their work, in turn, has an impact on values— sometimes well beyond their knowledge.
Impacts of Nanotechnology
1. Faster, smaller, and more powerful computers that consume far less power, with longer-lasting batteries. - Circuits made from carbon nanotubes could be vital in maintaining the growth of computer power, allowing Moore's Law to continue. 2.

Changed geology
Every time we destroy a patch of rainforest, this changes the future of Earth's geology. • We have transformed more than 50 per cent of Earth's land area for our own purposes. • Deforestation, farming, drilling, mining, landfills, dam-building and coastal reclamation are all having widespread effects on sedimentary processes. • Disrupting how layers of rock are laid down, which will be detectable thousands of years in the future.
Values shape how technologies are both developed and adopted.
Every time we make a decision about technology or science, we are making a values decision. - When we choose what to study, what to buy, or how to use a technology we are deciding what is most important to our families, in our jobs, and for our communities. - In this process—whether we are conscious of it or not—we look at the possibilities, reflect on our values, and then change the world—even if it is in a very small way. - This is perhaps most easily seen in the decisions we make as consumers. When we buy technologies, we are often motivated by our goals, hopes, and dreams. • We buy a hammer because we want to fix our house without having to pay an expensive contractor. • We buy a computer so that our children can be better prepared for school.
Paleolithic Age
Everyone worked to find food, because it was the key to the group's survival. • Some scientists believe that an equal relationship existed between Paleolithic men and women. • Some evidence suggests that some men and women may have hunted in monogamous pairs. • This means that a man and a woman worked together to find food for themselves and their children. • Such groupings became the first families.
Stone Age (Paleolithic Age)
Historians call the early period of human history
