Best of Futurology Episode 8: Inventions of The Future (Documentary)
An invention is a unique or novel device, method, composition or process. It may be an improvement upon a machine or product, or a new process for creating an object or a result. An invention that achieves a completely unique function or result may be a radical breakthrough. Such works are novel and not obvious to others skilled in the same field. History shows that turning the concept of an invention into a working device is not always swift or direct. Inventions may also become more useful after time passes and other changes occur.
An invention can serve many purposes. These purposes might differ significantly and may change over time. An invention, or a further-developed version of it, may serve purposes never envisioned by its original inventor(s) or by others living at the time of its original invention. As an example, consider all the kinds of plastic developed, their many uses, and the significant growth this material invention is still undergoing.
