Lesson 1 Human Limitations
Technology is important in everyday life. Imagine life without technology.
What else can our senses and body allow us to do?
However, there are limitations to what humans can do.
We cannot hear or see things which are tiny, too soft or well-hidden.
We cannot fly or walk very fast or too far without the aid of technology.
Humans are able to overcome their limitations. Devices are used to overcome the limitations and problems faced by humans.
