Introduction

There are still some minor issues with the page:

1. Correct the references in the 3rr block.
2. Correctly implement the footnote command (see Readme) in the 5th block
3. Correct the references in the paragraph after the plotted graphs. The section starts with " More recently, a distinction between aleatoric and epistemic uncertainty has also been ....".
4. Reference what you mean by Section 3,4 and 5 in the paragraph after Figure 2.1
5. Correct the false reference: "(cf.\ Fig.\ \ref{fig:image})" . This is probably due to two images not correctly being represented on the page. See the error message when building the book.
6. Fix "{numref}Table-image" under Figure 2.2
7. Correct some typos in the Quantum Mechanics example like: "antoher", "quautm" The remaining part looks good!
