    Notes: [Auszug] Observation of the rotational brownian motion of a very fine wire immersed in a gas led to one of the most important ideas of equilibrium statistical mechanics. Namely, the many-particle problem of a large number of molecules colliding with the wire can be represented by just two macroscopic ...

    Notes: [Auszug] ...Biocatalysis underpins some of the oldest chemical transformations known to humans, for brewing predates recorded history. The Sumerians, for instance, produced at least 19 different types of beer. This practical art was the fuse for the explosion in understanding of organic and biological ...
