Biology studies the variety of life (clockwise from top-left) E. coli, tree fern, gazelle, Goliath beetle

Biology (from Greek Βìο meaning life and Λoγος meaning the study of) is the study of life. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. However, together they address phenomena related to living organisms (biological phenomena) over a wide range of scales, from biophysics to ecology. It is concerned with the characteristics, classification, and behaviors of organisms, how species come into existence, and the interactions they have with each other and with the natural environment.

Many of the subdisciplines of biology, such as botany, zoology, and medicine are ancient. However, biology as a unified science first developed in the nineteenth century, as scientists discovered that all living things shared certain fundamental characteristics and were best studied as a whole. Today biology is one of the most prominent scientific fields. Over a million papers are published annually in a wide array of biology and medicine journals[1], and biology is a standard subject of instruction at schools and universities around the world.

As such a vast field, biology is divided into a number of subdisciplines. The old division by type of organism remains with botany encompassing the study of plants, zoology the study of animals, microbiology the study of microorganisms, and other similar disciplines. The field is also divided by the scale being studied: molecular biology looks at the fundamental chemistry of life; cellular biology looks a the basic building block of all life the cell; Physiology looks at the internal structure of organism; and ecology looks at how various organisms interrelate.

Geography


Geography (from the Greek words Ge (γη) or Gaea (γαια), both meaning "Earth", and graphein (γραφειν) meaning "to describe" or "to write"or "to map") is the study of the earth and its features and of the distribution of life on the earth, including human life and the effects of human activity.[1] A literal translation would be "to describe the Earth". The first person to use the word "geography" was Eratosthenes (275-195 BCE). Four historical traditions in geographical research are the spatial analysis of natural and human phenomena (geography as a study of distribution), area studies (places and regions), study of man-land relationship, and research in earth sciences. [2] Nonetheless, modern geography is an all-encompassing discipline that foremost seeks to understand the world and all of its human and natural complexities-- not merely where things are, but how they have changed and come to be. It is said to be the "mother of all sciences" and "the synthesizer of knowledge." As "the bridge between the human and physical sciences," geography is divided into two main branches, human geography and physical geography.[3]

Isosceles Triangle


 [ Invalid Attachment ]






An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length b and the remaining side has length a. This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg).

A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal. Another special case of an isosceles triangle is the isosceles right triangle

Mammary gland


Mammary glands are the organs that, in the female mammal, produce milk for the sustenance of the young. These exocrine glands are enlarged and modified sweat glands and are the characteristic of mammals which gave the class its name.

Palmer micrometer

http://le.talou.free.fr/images/palmer.jpg

Micromètre ou palmer.
Capable de mesurer une côte extérieure avec une précision de l'ordre du 100ème de mm, il comprend un corps en demi cercle (1), supportant à l'une de ses extrémités une enclume fixe (2) et à l'autre extrémité une douille cylindrique fixe, filetée te graduée en mm (3). Sur cette douille est visser une broche mibile (4) supportée par un tambour, gradué avec 50 divisions (5).
Comme un pied à coulisse, il est possible d'immobiliser la broche à l'aide d'un système de blocage (66), pour faciliter la lecture.

A l'exception de l'attention portée au serrage de la pièce, la précaution principale d'utilisation consiste à ne pas commettre d'erreur de lecture. En effet, il faut deux tours de vernier (5) pour "couvrir" 1 mm.

Le micromètre d'intérieur ou jauge micrométrique est identique ou palmer et permet de mesurer une cote intérieure. Même principe et précaution d'utilisation.
