<p>The article calls attention to a distinction in English between the terms ‘engineering science’ and ‘engineering sciences’ (singular and plural): the former appearing to be broader and denote educational programs that include more than technical engineering, the latter to be a collective noun for diverse engineering sciences such as mechanics, statics, dynamics, electronics, et al. Furthermore, it calls attention to a professional society and journals dedicated to engineering science in the singular, briefly reflects on personal interaction with the Department of Engineering Science at Pennsylvania State University, and selectively dips into historical-philosophical literature. The article also provides reflections on ‘engineering wonder’.</p>
