Whether you are a university professor, researcher at a think tank, graduate student, or analyst at a private firm, chances are that at some point you have presented your work in front of an audience. Most of us approach this task by converting a written document into slides, but the result is often a text-heavy presentation saddled with bullet points, stock images, and graphs too complex for an audience to decipher-much less understand. Presenting is fundamentally different from writing, and with only a little more time, a little more effort, and a little more planning, you can communicate your work with force and clarity. Designed for presenters of scholarly or data-intensive content, Better Presentations details essential strategies for developing clear, sophisticated, and visually captivating presentations. Following three core principles-visualize, unify, and focus-Better Presentations describes how to visualize data effectively, find and use images appropriately, choose sensible fonts and colors, edit text for powerful delivery, and restructure a written argument for maximum engagement and persuasion. With a range of clear examples for what to do (and what not to do), the practical package offered in Better Presentations shares the best techniques to display work and the best tactics for winning over audiences. It pushes presenters past the frustration and intimidation of the process to more effective, memorable, and persuasive presentations.

In recent decades, we have witnessed an explosion in the number of visual images we encounter, as our lives have become increasingly saturated with screens. From Google Images to Instagram, video games to installation art, this transformation is confusing, liberating and worrying all at once, since observing the new visuality of culture is not the same as understanding it. Nicholas Mirzoeff is a leading figure in the field of visual culture, which aims to make sense of this extraordinary explosion of visual experiences. As Mirzoeff reminds us, this is not the first visual revolution; the 19th century saw the invention of film, photography and x-rays, and the development of maps, microscopes and telescopes made the 17th century an era of visual discovery. But the sheer quantity of images produced on the internet today has no parallels. In the first book to define visual culture for the general reader, Mirzoeff draws on art history, theory and everyday experience to provide an engaging and accessible overview of how visual materials shape and define our lives.

Ada Lovelace, the daughter of Lord Byron was born in 1815 just after the Battle of Waterloo, and died aged 36, soon after the Great Exhibition of 1851. She was connected with some of the most influential and colourful characters of the age: Charles Dickens, Michael Faraday, Charles Darwin and Charles Babbage. It was her work with Babbage that led to her being credited with the invention of computer programming and to her name being adopted for the programming language that controls the US military machine. Ada personified the seismic historical changes taking place over her lifetime. This was the era when fissures began to open up in culture: romance split away from reason, instinct from intellect, art from science. Ada came to embody these new polarities and her life heralded a new era: the machine age.Reissued to coincide with the bicentenary of Ada's birth, The Bride of Science is a fascinating examination of an extraordinary life offering devastating insight into the seemingly unbridgeable gulf between art and science, the consequences of which are still with us today.
