In this gallery there are no pictures of beer. If you want to see a beer, go to a bar. Here only the beauty of yeast S. cerevisiae is shown. Why?, you may ask. Perhaps the answer lies in the words of Jules Henri Poincaré: “The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful. If nature were not beautiful it would not be worth knowing, and life would not be worth living.”
