A markdown list in `report.md` breaks compilation

In the #Introduction section I had a paragraph with text. Compilation is broken if a list like this is added:

```
1. The changes of position and velocity as given by Newton's laws of motion.
2. The stresses as given by the elasticities and motions, also taking into account the
osmotic pressures as given from the chemical data.
3. The chemical reactions.
4. The diffusion of the chemical substances. The region in which this diffusion is possible is given from the mechanical data.
```

although that's valid markdown.

It should be maybe indicated which is the valid subset of markdown that works?
