After that from 1866 to 1879 he spent several years in Le Havre, where his father was at that time first deputy. Meanwhile, Rolland developed an extreme passion for mathematics to such an extent that his health suffered and he was forced to give it up and take a break. He continued to live in Le Havre and after the death of his father there he got to know a pharmacist who studied mushrooms using the book by Julius Vincenz von Krombholz, Krombholz.

1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pleurotus Cornucopiae
''Pleurotus cornucopiae'' is a species of edible fungus in the genus ''Pleurotus'', It is quite similar to the better-known ''Pleurotus ostreatus'', and like that species is cultivated and sold in markets in Europe and China, but it is distinguished because its gills are very decurrent, forming a network on the stem. Naming The species name means "of the Cornucopia" (horn of plenty), which is appropriate since the mushrooms are edible and sometimes take on a shape similar to a drinking horn. The original definition of this species, or basionym, was made by Jean-Jacques Paulet in 1793 as ''Dendrosarcos cornucopiae''. At a time when most gilled mushrooms were lumped into genus ''Agaricus'', Paulet invented genus ''Dendrosarcos'', later Latinised to ''Dendrosarcus'', for those having an excentric or missing stipe. In fact those fungi have not been found to be a closely related group, and today the name only has historical interest, though the taxonomic rules imply that it still ne ...
