LEAD-IN

 

1. Basic nanomachines are already in use. Nanobots will be the next generation of nanomachines. Advanced nanobots will be able to sense and adapt to environmental stimuli such as heat, light, sounds, surface textures, and chemicals; move, communicate, and work together; conduct molecular assembly; and, to some extent, repair or even replicate themselves.

 

These are nanobot prototypes that might be created. List as many imaginative uses for them as you can think of, justify your ideas.

WORD STUDY

 

3. Translate the following definitions and memorize the terms:

 

nanotechnology (n) - technology that deals with dimensions and tolerances of less than 100nanometers, esp. the manipulation of individual atoms and molecules;

 

semiconductor (n) - an intermediate between a metal and an insulator (germanium, silicon) that has an electrical conductivity that increases with temperature;

 

detect (v) - to find something or discover that it is present somewhere by using equipment or making an investigation;

 

performance (n) - the capabilities of a machine or product; manner or quality of functioning; scale (n) - a ratio of size in a map, model, drawing, or plan; an established measure or

 

standard;
