Excerpt from The Biological Relation of Aquatic Plants to the Substratum The observations of hoppe-seyler, then, show that the upper layers of the water of the lake to a depth of 2 meters are practically satu rated with oxygen, not only where larger aquatic plants are growing, but where there are no such plants. These plants can therefore have no practical effect in increasing the oxygen content of the superficial layer Of water. Since his observations show further that in no part of the lake, even at great depths, and in other situations destitute of larger aquatic plants, is there more than a small quantity of uncombined carbon dioxid present, it is clear that the larger plants are not essential for the removal of this gas from the water. It is removed rather as a free gas, by the formation of carbonates. The statement, however, that the larger aquatic plants can not be regarded as essential for the furnishing of oxygen to the animals of a lake or for the removal of carbon dioxid injurious to those animals must be understood as applying only to lakes of considerable size - not to small ponds nor to standing aquaria.

How capitalism first promoted fossil fuels with the rise of steam power The more we know about the catastrophic implications of climate change, the more fossil fuels we burn. How did we end up in this mess? In this masterful new history, Andreas Malm claims it all began in Britain with the rise of steam power. But why did manufacturers turn from traditional sources of power, notably water mills, to an engine fired by coal? Contrary to established views, steam offered neither cheaper nor more abundant energy—but rather superior control of subordinate labour. Animated by fossil fuels, capital could concentrate production at the most profitable sites and during the most convenient hours, as it continues to do today. Sweeping from nineteenth-century Manchester to the emissions explosion in China, from the original triumph of coal to the stalled shift to renewables, this study hones in on the burning heart of capital and demonstrates, in unprecedented depth, that turning down the heat will mean a radical overthrow of the current economic order.

The seashore has long been the subject of fascination and study - the Ancient Greek scholar Aristotle made observations and wrote about Mediterranean sea urchins. The considerable knowledge of what to eat and where it could be found has been passed down since prehistoric times by oral tradition in many societies - in Britain it is still unwise to eat shellfish in months without an 'r' in them. Over the last three hundred years or so we have seen the formalization of science and this of course has touched intertidal ecology. Linnaeus classified specimens collected from the seashore and many common species (Patella vulgata L. , Mytilus edulis L. , Littorina littorea (L. )) bear his imprint because he formally described, named and catalogued them. Early natural historians described zonation patterns in the first part of the 19th century (Audouin and Milne-Edwards, 1832), and the Victorians became avid admirers and collectors of shore animals and plants with the advent of the new fashion of seaside holidays (Gosse, 1856; Kingsley, 1856). As science became professionalized towards the end of the century, marine biologists took advantage of low tides to gain easy access to marine life for taxonomic work and classical studies of functional morphology. The first serious studies of the ecology of the shore were made at this time (e. g.

Herbert Simon's classic work on artificial intelligence in the expanded and updated third edition from 1996, with a new introduction by John E. Laird. Herbert Simon's classic and influential The Sciences of the Artificial declares definitively that there can be a science not only of natural phenomena but also of what is artificial. Exploring the commonalities of artificial systems, including economic systems, the business firm, artificial intelligence, complex engineering projects, and social plans, Simon argues that designed systems are a valid field of study, and he proposes a science of design. For this third edition, originally published in 1996, Simon added new material that takes into account advances in cognitive psychology and the science of design while confirming and extending the book's basic thesis: that a physical symbol system has the necessary and sufficient means for intelligent action. Simon won the Nobel Prize for Economics in 1978 for his research into the decision-making process within economic organizations and the Turing Award (considered by some the computer science equivalent to the Nobel) with Allen Newell in 1975 for contributions to artificial intelligence, the psychology of human cognition, and list processing. The Sciences of the Artificial distills the essence of Simon's thought accessibly and coherently. This reissue of the third edition makes a pioneering work available to a new audience.
