This article presents the results of a comparative study of two groups of learners--group 1 (25 non-science students) and group 2 (25 A-level physics students). It explores the extent to which their feelings and emotions in conjunction with their knowledge about nuclear energy impacts and influences their views and feelings about the use of nuclear energy as an alternative source of energy. The findings reveal that after exposure to learning about topics in nuclear energy the non-science students were more accepting and open in respect of the use of nuclear energy than the science students. In fact, over 80% of the non-science students indicated that they would support nuclear energy as a viable alternative energy source while only about 45% of the physics students said that they would.
