  Joseph Priestley, FRS (13 March 1733 (O.S.) – 6 February 1804) was an 18th-century English theologian, Dissenting clergyman, natural philosopher, chemist, educator, and political theorist who published over 150 works. In “Experiments and Observations on Different Kinds of Air,” he reviews experiments with gases. A common theme in this work is measuring the volumes of gases held in glass tubes, and their increase or decrease when exposed to other substances. He also tests the effects of gases on mice, plants and insects.  
  Priestley demonstrated that fixed air (now known as CO2) can be produced from several reactions including alcoholic fermentation, combustion and a mixture of oil of vitriol and chalk (sulfuric acid and calcium oxide). He also showed that it is soluble in water, and that its toxic effects can be reduced when agitated in water. In other experiments, he showed that combinations of gases can mix to form a smaller volume than the sum of both separate gases, as when he combined common air (atmospheric air) with nitrous air (nitric oxide, NO).  
  For some experiments, Priestley tests whether the properties of gases change when stored. He finds that inflammable air (hydrogen, H2 or a mixture of hydrocarbons) becomes less flammable but retains its toxic properties. 
  Also interested in electricity, Priestley tests the effects of gases on sparks. While he finds that gases are generally good insulators, he also finds that some gases change the colors of electric sparks. He also discovers that some mixtures of air explode in their entirety, while others must be combined with common air in order to burn.  
  Priestley uses several terms common to the study of natural philosophy, or chemical experiments as known today. Some of the terms are parts of obsolete theories or are old names for chemicals now given standard names. To better understand Priestley's observations, the following terms are defined according to their present names. here

  The Theory That Would Not Die -...

  Bayes' rule appears to be a straightforward, one-line theorem: by updating our initial beliefs with objective new information, we get a new and improved belief. To its adherents, it is an elegant statement about learning from experience. To its opponents, it is subjectivity run amok.In the first-ever account of Bayes' rule for general readers, Sharon Bertsch McGrayne explores this controversial theorem and the human obsessions surrounding it. She traces its discovery by an amateur mathematician in the 1740s through its development into roughly its modern form by French scientist Pierre Simon Laplace. She reveals why respected statisticians rendered it professionally taboo for one hundred and fifty years—at the same time that practitioners relied on it to solve crises involving great uncertainty and scanty information, even breaking Germany's Enigma code during World War II, and explains how the advent of off-the-shelf computer technology in the 1980s proved to be a game-changer. Today, Bayes' rule is used everywhere from DNA decoding to Homeland Security.Drawing on primary source material and interviews with statisticians and other scientists, The Theory That Would Not Die is the riveting account of how a seemingly simple theorem ignited one of the greatest controversies of all time.

  A Brief History of a Perfect Future 
  What if, instead of trying to predict the future, we could just pick the one we want—and then invent it? Well, we can. 
  Think of the wealth of technological resources already available to us. The computing power in that smartphone in your pocket could have guided 120 million Apollo-era spacecraft to the moon and back. A gigabyte of memory cost $300,000 in the 1980s—today, it costs a fraction of a penny. Now, try to imagine 2050, when your computing devices will be a million times more powerful or available at one-millionth of today’s prices. 
  In this deeply researched and compelling book, the authors do the imagining for you, describing seven so-incredible-as- to-be-almost-magical capabilities that will be available by 2050 in computing, communication, information, genomics, energy, water, and transportation. You may finally get that flying car, have ample water even in a desert, and be treated for disease through microscopic robots in your bloodstream. 
  Drawing on their decades of experience helping major organizations formulate strategies for innovation, the authors demonstrate how to use combinations of those seven capabilities to imagine “perfect” futures, whether that means reversing climate change, resolving today’s disinformation crisis, or living 20 years longer. This book paints visions of how the world could—and should—look as we pass the planet on to future generations. 
  We can use those visions to start inventing a perfect future—today.

  In the Herbarium - The Hidden...

  Collections of preserved plant specimens, known as herbaria, have existed for nearly five centuries. These pressed and labeled plants have been essential resources for scientists, allowing them to describe and differentiate species and to document and research plant changes and biodiversity over time—including changes related to climate.Maura C. Flannery tells the history of herbaria, from the earliest collections belonging to such advocates of the technique as sixteenth-century botanist Luca Ghini, to the collections of poets, politicians, and painters, and to the digitization of these precious specimens today. She charts the growth of herbaria during the Age of Exploration, the development of classification systems to organize the collections, and herbaria's indispensable role in the tracking of climate change and molecular evolution. Herbaria also have historical, aesthetic, cultural, and ethnobotanical value—these preserved plants can be linked to the Indigenous peoples who used them, the collectors who sought them out, and the scientists who studied them.This book testifies to the central role of herbaria in the history of plant study and to their continued value, not only to biologists but to entirely new users as well: gardeners, artists, students, and citizen-scientists.
