On June 6,the world paused to observe a momentous occasion: the first transit of Venus between the Earth and the Sun in more than a century. Through that observation, astronomers could calculate the size of the solar system —but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Overcoming incredible odds and political strife, astronomers from Britain, France, Russia, Germany, Sweden, and the American colonies set up observatories in the remotest corners of the world, only to be thwarted by unpredictable weather and warring armies. Fortunately, transits of Venus occur in pairs; eight years later, they would have another opportunity to succeed. Chasing Venus brings to life the personalities of the astronomers who embarked upon this complex and essential venture and paints a vivid portrait of the collaborations, the rivalries, and the volatile international politics that hindered them at every turn. Thanks to these scientists, neither our conception of the universe nor the nature of scientific research would ever be the same. Andrea Wulf was born in India and moved to Germany as a child. She lives in London, where she trained as a design historian at the Royal College of Art. She is the brightest star in the night sky and visible even on a clear day. Some saw her as the harbinger of morning and evening, of new seasons or portentous times. In British astronomer Edmond Halley published a ten-page essay which called upon scientists to unite in a project spanning the entire globe — one that would change the world of science forever. On 6 JuneHalley predicted, Venus would traverse the face of the sun — for a few hours the bright star would appear as a perfectly black circle. The only problem was that the so-called transit of Venus is one of the rarest predictable astronomical events. Transits always arrive in pairs — eight years apart — but with an interval of more than a century before they are then seen again. Only once before, Halley said, inhad an astronomer called Jeremiah Horrocks observed the event. The next pair would occur in and — and then again in and Halley was sixty years old when he wrote his essay and knew that he would not live to see the transit unless he reached the age ofbut he wanted to ensure that the next generation would be fully prepared. By choosing to write in Latin, the international language of science, he hoped to increase the chances of astronomers from across Europe acting upon his Chasing Venus: The Race to Measure the Heavens. The more people he reached, the greater the chance of success. It was essential, Halley explained, that several people at different locations across the globe should measure the rare heavenly rendezvous at the same time. They came together in the spirit of the Enlightenment. The race to observe and measure the transit of Venus was a pivotal moment in a new era — one in which man tried to understand nature through the application of reason. This was a century in which science was worshipped, and myth at last conquered by rational thought. Man began to order the world according to these new principles. The Swedish botanist Carl Linnaeus classified plants according to their sexual organs, and in Samuel Johnson imposed order upon language when he had compiled the first English dictionary. Slowly the workings of nature became clearer. Humankind believed it was marching along a trajectory of progress. Observation, enquiry and experimentation were the building blocks of this new understanding of the world. With progress as the leading light of the century, every generation envied the next. Whereas the Renaissance had looked back upon the past as the Golden Age, the Enlightenment looked firmly to the future. Until the early seventeenth century man had observed the sky with his naked eye, but technology was slowly catching up with the reach of his ambitions and theories. Astronomy had changed from a science which mapped stars to one which sought to understand the motion of planetary bodies. As astronomers gazed at the stars, they were no longer in search of God but of the laws governing the universe. By the time Halley called upon his fellow astronomers to view the transit of Venus, the universe was regarded as running like a divinely created clockwork according to laws which humankind had only to comprehend and compute. But man still lacked the knowledge of the actual size of the solar system — an essential piece of the celestial jigsaw puzzle. Already in the early seventeenth century Kepler had discovered that by knowing how long Chasing Venus: The Race to Measure the Heavens took for a planet to orbit the sun, the relative distance between the sun and the planet could be calculated Chasing Venus: The Race to Measure the Heavens longer it took a planet to orbit the sun, the further away it was. From this he had been Chasing Venus: The Race to Measure the Heavens to work out the distance between the earth and the sun relative to the other planets — a unit of measurement that became the basis for calculating comparative distances in the universe. The only problem was that no one had as yet been able to quantify that distance in more specific terms. Eighteenth-century astronomers had a map of the solar system, but no idea of its true size. Without knowing how far the earth really was from the sun, such a map was all but useless. Venus, so Halley believed, was the key to unlocking this secret. Chasing Venus: The Race to Measure the Heavens the brightest star in the sky, Venus became the perfect metaphor for the light of reason that would illuminate this new world and extinguish the last vestiges of the Dark Ages. Not only had he spent one and a half hours in a diving bell submerged almost twenty metres deep in the Thames, he had also undertaken three expeditions to the South Atlantic as the first European to map the southern night sky with a telescope. Halley was asking his future disciples to embark on a project that was bigger and more visionary than any scientific endeavour previously undertaken. The dangerous voyages to remote outposts would take many months, possibly even years. Astronomers would be risking their lives for a celestial event that would last just six hours and be visible only if weather conditions permitted it. In preparation for it, scientists would need to secure funding for the best telescopes and instruments as well as for travel, accommodation and salaries. They would have to convince their respective monarchs and governments to support their individual efforts and would have to coordinate their own observations with those from other countries. Nations locked in battle would have to work together in the name of science for the first time ever. Each observer would have to add his or her observations to the pool of international data. No single result would be of any use without the others. In order to calculate the distance between the sun and the earth, astronomers would have to compare the figures and consolidate the different data into one definitive result. Timings obtained Chasing Venus: The Race to Measure the Heavens the world using a disparate range of clocks and telescopes would somehow have to be standardised and made comparable. The transit of Venus observations were to be the most ambitious scientific project that had ever been planned — an extraordinary undertaking in an era when a letter posted in Philadelphia took two to three months to reach London, and when the journey from London to Newcastle was six days. It took a great leap of the imagination to propose that astronomers should travel thousands of miles into the Chasing Venus: The Race to Measure the Heavens far north and south, laden with instruments weighing more than half a ton. Their idea of calculating exact distances in space was a bold concept too, considering that clocks were still not accurate enough to measure longitude precisely, and there was as yet no standardised measurement on Earth: an English mile was a Chasing Venus: The Race to Measure the Heavens length from a mile in German-speaking countries — which also varied between northern Germany and Austria. In France alone there were Chasing Venus: The Race to Measure the Heavens, different units of measurement — which varied even between neighbouring villages. In light of this, the idea of merging hundreds of observations taken by astronomers across the world to find one common value seemed outrageously ambitious. The scientists, who were to leave their observatories in the learned centres of Europe to view Venus from remote outposts of the known world, made for strange adventurers too. At first sight they might not have looked like heroic explorers, but as they chased Venus across the globe they did so with extraordinary intrepidity, bravery and ingenuity. On 6 June and again on 3 Juneseveral hundred astronomers all over the world pointed their telescopes towards the sky to see Venus travel across the sun. They ignored religious, national and economic differences to unite in what was the first global scientific project. This is their story. Excerpted by permission of Alfred A.

Like a nonfiction National Treasure with myriads of Nicholas Cages darting around—in a good way. Enlightening Enlightenment In the late 18th century, European astronomers scurried about the globe measuring the transit of Venus, hoping, at last, to learn the size of our universe. Until this busy narrative, Wulf had turned her eyes more earthward with three previous outings about gardens The Founding Gardeners: The Revolutionary Generation, Nature, and the Shaping of the American Nation, etc. Their calculation—transit-derived—was quite close. More than pages of Chasing Venus: The Race to Measure the Heavens matter reveal the sturdy research undergirding the lively narrative. An authoritative, engaging study of plant life, accessible to younger readers as well as adults. A neurobiologist reveals the Chasing Venus: The Race to Measure the Heavens of the natural world through stories of plant migration. He smoothly balances expansive historical exploration with recent scientific research through stories of how various plant species are capable of migrating to locations throughout the world by means of air, water, and even via animals. They often continue to thrive in spite of dire obstacles and environments. One example is the response of plants following the Chernobyl nuclear disaster. Mancuso also tracks the journeys of several species that might be regarded as invasive. Even without actual photos and maps, it would have been beneficial to readers to include more finely detailed plant and map renderings. Jahren transcends both memoir and science writing in this literary fusion of both genres. Both of these early influences engrossingly combine in this adroit story of a dedication to science. The heroes in this tale are the plants that the author studies, and throughout, she employs her facility with words to engage her readers. We learn much along the way—e. We are each given exactly one chance to be. Each of us is both impossible and inevitable. Every replete tree was first a seed that waited. This is her story, after all, and we are engaged beyond expectation as she relates her struggle in building and running laboratory after laboratory at the universities that have employed her.
