It is considered one of the oldest foods and most appreciated beverages of the world - chemical remains were found on fragments of a more than 4.000 old jar, the Mesopotamians guaranteed its purity by death penalty and the old Egyptian considered it an essential part of the afterlife - the preferred drink of the gods of the Vikings - and today of geologist, known also as beer.Geologists love beer for a simple reason: it makes you think a lot about geology…(and as a popular side-effect it is tasty)...

Time for a new epoch? - the Anthropocene

The notion that the influence on earth's systems by humankind is so great that this phase of earth's history needs a proper name is not new, already in 1873 the Italian geologist Antonio Stoppani suggested the term Anthropozoic , in 1879 the American geologist Joseph LeConte discusses in his textbook the Psychozoic and in 1927 the French philosoph Édouard Louis Emmanuel Julien Le Roy adopts the Noosphere from Russian mineralogist Vladimir Vernadsky to denote the third epoch of earth - after the inanimate geosphere and animate biosphere the epoch of human thought has begun...

The discovery of the ruins of ice: The birth of glacier research

"It has already been said, that no small part of the present work refers to the nature and phenomena of glaciers. It may be well, therefore, before proceeding to details, to explain a little the state of our present knowledge respecting these great ice-masses, which are objects of a kind to interest even those who know them only from description, whilst those who have actually witnessed their wonderfully striking and grand characteristics can hardly need an inducement to enter into some inquiry respecting their nature and origin." James, D...
