The document discusses nanotechnology and how it allows working at the nanoscale level. It describes how nanotechnology could be used in areas like cosmetics, dentistry, medicine, vehicles, and computers. It also discusses potential risks of nanotechnology like health risks and environmental risks due to the small scale and lack of knowledge. The document advocates for using both empirical scientific research along with philosophy to forecast and evaluate implications of nanotechnology through informed imagination.

3. Scientists Scientists : empirical research and discovery of facts about nature Philosophers: forecasting and evaluating the implications Informed imagination Use the scientific method Use experiences to confirm hypotheses and theories How do we explain natural phenomena?

4. Philosophers Scientists: empirical research and discovery of facts about nature Philosophers : forecasting and evaluating the implications Informed imagination

5. Philosophers Scientists: empirical research and discovery of facts about nature Philosophers : forecasting and evaluating the implications Informed imagination Love of wisdom Big Questions: What is knowledge? What is truth? What does it mean to exist? What does it mean to be right or wrong, good or bad? What does it mean to be beautiful?

16. If Legos Were the Size of Atoms The advantages of working at the nanoscale Greater control and flexibility building from the ground up Special properties at the nanoscale

17. If Legos Were the Size of Atoms Increase flexibility and control but ... How many would you need? How would you see them? How would you work with them?
