The full form of PUS is Public Understanding of Science. It’s used on Academic & Science ,Language & Linguistics in Worldwide

Public awareness of science (PAwS), public understanding of science (PUS), or more recently, public engagement with science and technology (PEST) are terms relating to the attitudes, behaviours, opinions, and activities that comprise the relations between the general public or lay society as a whole to scientific knowledge and organisation. It is a comparatively new approach to the task of exploring the multitude of relations and linkages science, technology, and innovation have among the general public.^[1] While earlier work in the discipline had focused on augmenting public knowledge of scientific topics, in line with the information deficit model of science communication, the discrediting of the model has led to an increased emphasis on how the public chooses to use scientific knowledge and on the development of interfaces to mediate between expert and lay understandings of an issue.

The need to raise awareness and a greater general understanding of science and technology is now irrefutable as we live in a world increasingly dominated by science and its applications. Sadly there is still a great deal of misunderstanding and ignorance of science and technology mirroring in many ways the continuing problems with the basic skills in literary, numeracy and information technology capability. I fully accept that many of the following issues have been aired before but hope this article will trigger further constructive debate on this important subject. Schools, colleges and universities have a major role to play in this endeavour but with the need to establish a culture of lifelong learning other agencies must be involved and that most certainly includes the media. I prefer to use the expression ‘general understanding of science and technology’ as opposed to ‘public understanding of science and technology’. The latter can reinforce the false demarcation between science and the public namely between a sect or guild of scientists and the stereotyping of the rest of the populace.
