Balade d'hiver, couleurs d'automne (La Petite Collection) by Henry David Thoreau

By Henry David Thoreau

Henry David Thoreau ne s’est jamais contenté d’admirer l. a. Nature. Depuis sa retraite au milieu des bois, à Walden en 1845, jusqu’à ses longues promenades dans les forêts de l. a. Nouvelle-Angleterre, il n’a ecu de cesse de l. a. parcourir. Jour après jour, il a scrupuleusement consigné dans son Journal, dont « Balade d’hiver » (1846) et « Couleurs d’automne » (1862) sont tirés, chaque détail observé au cours de ses tours et los angeles moindre edition du paysage.

Sensible aux saisons du déclin, périodes propres à los angeles méditation, ce philosophe de los angeles nature s’emploie à décrypter les signes d’une harmonie universelle au sein de laquelle l’homme doit trouver sa position.

Banded Iron Formations: BIF From the beginning of the Archaean (around 3800 Ma) we find increasing accumulations of a peculiar rock type. BIF or Banded Iron Formations are sedimentary rocks found mainly in sequences older than 1800 Ma. The bands are alternations of iron oxide and chert (Fig. 14), sometimes repeated millions of times in microscopic bands (Fig. 15). 13 This fossil is Primaevifilum, from the Apex Chert in the Warrawoona rocks of Western Australia, dated about 3465 Ma. A photograph down a microscope a) shows a rather blurry outline, which caused unnecessary vicious criticism suggesting that it was not a cell and not a fossil.

A shield of perhaps 10 m (30+ feet) of water might have been needed to prevent damage to a normal early cell by UV radiation. However, the early evolution of the stromatolitic way of life by cyanobacteria may have been a response to UV radiation. With light (and UV) penetrating only a little way into the mat, bacteria were able to live essentially at the foodrich water surface without damage from UV. Cyanobacteria were not just existing at Warrawoona: they were already modifying their microenvironment for survival and success.
