What is Reddit's opinion of Spectrum of Belief: Joseph von Fraunhofer and the Craft of Precision Optics (Transformations: Studies in the History of Science and Technology)?

From 3.5 billion Reddit comments

Mathematics is not science either, granted it is used by scientists but the two are separate disciplines. Yes scientists can also be mathematicians and vice versa, there is no brick wall separating the two disciplines

Science is the process of making hypothesis to understand the universe, and if they can be proven false they are dropped or changed into another hypothesis that works better. That is the process of science. Engineering uses those principles from the Scientists and apply them to real world problems.

I recommend another book https://www.amazon.com/Spectrum-Belief-Fraunhofer-Transformations-Technology/dp/0262527235

The author was my professor at college. This book lays out the confusing lines of difference between engineering and science. You are hardly the first who have confused this issue.
