New techniques
Various new technologies are being used to make complex phenomena visible that would otherwise remain invisible to the human eye. For example, there are techniques to visualise sound waves, heat waves and stress patterns in materials.
These technologies are not yet impacting our normal everyday lives, but state-of-the-art hospitals are already using infrared cameras to measure heat and determine the course of blood vessels in humans. These blood vessels are then projected onto the body so that nursing staff are able to pinpoint the exact spot where a medical drip or injection can be administered. In this way medical blunders can be minimised yet further.
